Description

  The present invention relates to a non-slip processed glove and a method for manufacturing the same.

  Anti-slip gloves are used, for example, by workers in factories and the like, worn by workers during transport operations, and worn by drivers during driving.

  As this kind of non-slip processed gloves, for example, (1) one in which a plurality of convex parts made of rubber or the like are fixed in the form of dots on the outer surface of the palm region of a fiber glove body covering the wearer's hand. It is known.

  Further, (2) it is also known that a rubber or resin coat layer is provided in the palm region of a fiber glove body, and this coat layer has air permeability.

  Further, (3) it is known that a convex portion is fixed to the palm region of the outer surface of the knitted glove in the form of dots and a coat layer is applied to the palm region (Japanese Patent Laid-Open No. 2000-328328). And utility model registration No. 3004374). Japanese Patent Application Laid-Open No. 60-236737 discloses that a flexible resin film is deposited on the surface of the glove after the hard resin protrusions are scattered and adhered to the surface of the glove.

  Further, (4) a glove body provided with a coat layer and forming a convex portion on the outer surface of the coat layer is also known (see Utility Model Registration No. 3164008).

  However, (1) In the non-slip processed glove in which the convex portion is simply fixed to the palm region, when the object to be gripped is worn and gripped, a sufficient frictional force is exhibited in the convex portion. Since the fibers of the glove body are exposed between the convex portions, a sufficient frictional force cannot be obtained in this portion, and there is a problem that it is difficult to grip the object to be gripped.

  In addition, (2) Non-slip processed gloves with a coat layer in the palm area have a greater frictional force than non-processed fiber gloves, but when gripping objects such as cardboard However, there is a problem that a sufficient frictional force cannot be obtained and gripping is difficult.

  Further, (3) the anti-skid gloves described in JP 2000-328328 A, Utility Model Registration No. 3004374, and JP 60-236737 A have a convex portion. The convex part is buried in the coat layer. That is, for example, the non-slip processed glove described in JP-A-60-236737 uses a vinyl chloride base resin for both the hard resin protrusion and the flexible resin film, so that the hard resin protrusion protrudes from the flexible film. Without being buried in the flexible film. As described above, in these anti-slip gloves, the convex portions (projections) are buried in the resin, and as a result, a sufficient frictional force cannot be obtained, so that actual commercialization has not been achieved. Further, in the non-slip gloves described in Japanese Patent Application Laid-Open No. 2000-328328 and Utility Model Registration No. 3004374, the coat layer does not have air permeability. Has the problem of stuffiness. Furthermore, in the non-slip processed glove described in JP-A-60-236737, a flexible film is foamed to give air permeability, but the foamed part is broken in use. There exists a possibility that it may detach | leave and the process to foam is needed.

  Further, (4) In the non-slip processed glove described in Utility Model Registration No. 3164008, the convex portion is provided on the outer surface of the coat layer. The shape part tends to come off. For this reason, when it is used for a long period of time, there is a problem that the grip force is reduced due to the separation of the convex portion.

JP 2000-328328 A Utility Model Registration No. 3004374 JP-A-60-236737 Utility Model Registration No. 3164008

  The present invention has been made in view of these inconveniences, and can prevent a hand from becoming damp even if worn for a long time, and can exert a sufficient frictional force to reliably grip an object to be gripped. An object of the present invention is to provide a non-slip processed glove in which the convex portion is fixed to the glove body and is difficult to be removed, and the grip force is not easily lowered even when used for a long period of time, and a method for manufacturing the glove.

The invention made to solve the above problems is
A fiber glove body covering the wearer's hand;
A plurality of resin or rubber convex portions fixed to at least the palm region of the outer surface of the glove body,
The outer layer of the glove body is laminated on at least a region other than the convex portion of the palm region, and has a coat layer having air permeability,
In the anti-slip glove, the convex portion protrudes from the outer surface of the coat layer.

In the anti-slip glove, since the convex portion protrudes from the outer surface of the coat layer, the object to be grasped can be gripped by the portions of the plurality of convex portions, and the convex portion such as between the convex portions. Since the coat layer is provided in the other region and the fibers of the glove body are not exposed, the object to be grasped can be reliably grasped with a sufficient grip force.
Moreover, even if it wears for a long time, since a coat layer has air permeability, a hand is hard to get stuffy and it can wear comfortably.

  In the anti-slip gloves, “the convex portion protrudes from the outer surface of the coat layer” means that the convex portion penetrates the outer surface of the coat layer and is exposed, and the outer surface of the convex portion is coated. This is a concept including a state in which the layer forming material covers, but the convex portion protrudes from the average interface of the outer surface of the coat layer. Further, the “palm area” means an area (including a finger) that is an inner surface when the object is grasped and extends from the wrist to the fingertip.

  Moreover, in the said non-slip processed glove, it is preferable that the root part of the convex part is impregnated in at least the surface layer of the glove body. Thereby, a convex part is firmly fixed to a glove body, and it can prevent exactly that a convex part separates from a glove body at the time of use.

  Further, in the anti-slip processed glove, it is preferable to adopt a configuration in which the material constituting the coat layer is impregnated in the glove body and the coat layer is exposed on the inner surface of the glove body. As a result, a sufficient frictional force acts between the inner surface of the anti-slip glove and the wearer's palm, and the anti-slip glove is accurately prevented from slipping from the hand when holding the object to be gripped. can do. In other words, if the fiber is exposed from the inner surface of the glove body without forming a coat layer on the inner surface of the glove body, the fibers on the inner surface of the glove body will be in contact with the palm of the wearer. Sufficient frictional force does not work between the two, and there is a possibility that the glove body may be displaced in the direction of detachment from the hand when the object is gripped. On the other hand, according to the configuration in which the coat layer is exposed on the inner surface of the glove body, the wearer's palm is in contact with the coat layer, and sufficient frictional force acts between the two. It is possible to accurately prevent the anti-skid gloves from slipping from the hand while gripping, and thus the object to be gripped can be securely gripped.

  Moreover, in the said anti-skid gloves, it is preferable that the material which comprises the said coat layer employ | adopts the structure which is non-permeable with respect to the said convex-shaped part. Thereby, in manufacturing the anti-slip glove, for example, after fixing the convex part to the glove body, when applying the material constituting the coat layer in the range including the convex part in the palm region of the glove body, It is difficult to form a coat layer on the outer surface of the convex portion. In other words, for example, when the convex portion and the coat layer are made of the same material or materials that easily adhere to each other (when made of a material having permeability), the outer surface of the convex portion is formed by the above-described method. There is a possibility that the coat layer is formed thick. On the other hand, even if the coating layer is not formed or formed on the outer surface of the convex portion due to the material constituting the coating layer being impermeable to the convex portion as described above. It becomes a relatively thin coat layer, and the object to be grasped can be accurately grasped by the plurality of convex portions.

  The above-mentioned “non-permeable” is sufficient if it is a material that does not penetrate into the convex portion within the time required for manufacturing as described above, and penetrates into the convex portion after a longer time than the time required for production. Even such materials are within the technical scope of “impermeable”.

  In the case of adopting the above configuration, the material constituting the convex portion contains a vinyl chloride resin or vinyl chloride-vinyl acetate copolymer resin as a main component, and the material constituting the coat layer is made of polyurethane as a main component. Including configurations can be employed. Thereby, the material which comprises a coat layer has non-permeability with respect to a convex-shaped part. In addition, it is possible to mix a plasticizer, a stabilizer, and the like with the material constituting the convex portion. In this case, the above-mentioned “main component” is the most resin component except for these blends. Means many ingredients. Similarly, the “main component” of the material constituting the coat layer also means the largest component among the rubber components.

  Moreover, in the said anti-slip | slipped glove, it is preferable to employ | adopt the structure by which the convex-shaped part is formed hollow. As a result, when the object to be grasped is gripped, the convex portion is easily deformed, and this deformation increases the contact area between the convex portion and the object to be grasped, thereby obtaining a sufficient frictional force. Become.

The present invention also provides:
Convex part forming step of coating a convex part forming material mainly composed of resin or rubber on at least the palm region of the outer surface of the fiber glove body covering the wearer's hand; and
A coat layer forming step in which a coat layer is formed on the outer surface of the glove body in a region other than the convex portion of the palm region so that the outer surface is lower than the convex portion;
The coat layer forming step
A coating layer material deposition step of depositing a coating layer forming material containing a resin or rubber as a main component and a solvent on the glove body;
And a porous process for extracting the solvent of the coating layer forming material deposited on the glove body.

  In the non-slip glove manufactured by the manufacturing method, the coat layer has air permeability, so that it is possible to prevent the hands from being damp even if worn for a long time, and the convex portion and the coat as described above. A sufficient grip force can be exhibited by the layer, and the object to be grasped can be securely grasped.

  As described above, the anti-slip gloves can prevent the hands from getting damp even if worn for a long time, and can also hold the object to be grasped with a sufficient grip force. In addition, since the convex portion is fixed to the glove body and the convex portion is not easily detached, the grip force is not easily lowered even when used for a long period of time.

FIG. 1 is an electron micrograph corresponding to FIG. It is typical explanatory drawing which shows the modification of FIG. It is a flowchart which shows the manufacturing method of the anti-skid gloves of FIG. It is a schematic front view which shows the anti-skid | work glove which concerns on other embodiment of this invention. It is a figure showing the result of experiments, such as moisture permeability in Example 1. It is a figure showing the result of experiment, such as a dynamic friction coefficient in Example 1 and 2.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

  1 includes a fiber glove body 3 that covers the wearer's hand, and a plurality of convex portions 5 that are fixed to the palm region of the outer surface of the glove body 3 in a scattered manner. A coat layer 7 laminated on the palm region of the outer surface of the glove body 3 is provided.

  The glove body 3 is knitted into a glove shape with fibers made of wooly nylon or the like, and has air permeability. In addition, the thickness of the cloth of the glove body 3 can be about 0.6 mm, and is preferably 0.2 mm or more and 1.0 mm or less, more preferably 0.4 mm or more and 0.8 mm or less at the center of the palm. This is because if it is thinner than the lower limit value, the strength of the glove body 3 is insufficient, and if it is larger than the upper limit value, workability at the time of wearing decreases. In addition, this thickness can be made into the average value of the result measured in five places, for example using brand name "Dial Cygness Gauge DS-1211 (made by Niigata Seiki Co., Ltd.)."

  In addition, the fiber which comprises the glove body 3 is not limited to woolly nylon, and various fibers can be employed, such as polyester, cotton, rayon, acrylic, aramid, high-strength polyethylene, polyurethane, and the like. In addition to organic fibers, stainless steel and glass fibers can also be used. The fibers constituting the glove body 3 are preferably nylon or polyester long fibers for applications that do not want to generate dust. The fibers constituting the glove body 3 are made of para-aramid (paraphenylene terephthalamide, for example, “Kevlar (DuPont)”, high-strength polyethylene (for example, for applications requiring cut resistance) It is preferable to use a trade name “Dyneema (manufactured by Toyobo Co., Ltd.)”, a composite fiber containing a fine metal wire or glass fiber, etc. The fibers constituting the glove body 3 may be the above-mentioned various fibers alone or in combination. In addition, as a means for forming a glove shape, for example, seamless knitting without knitting can be adopted, but for example, a fabric constituting the upper part and a fabric constituting the palm part are sewn together. It can also be provided in a glove shape.

  Moreover, the sleeve part 3a of the glove body 3 has elasticity in the circumferential direction, and is thereby provided so as to be able to expand and contract in the radial direction. Further, the part of the glove body 3 closer to the fingertip than the sleeve 3a is also stretchable in the circumferential direction and provided so as to be expandable and contractable in the radial direction. Here, the sleeve part 3a has larger elasticity than the other part (the part on the fingertip side from the sleeve part 3a), and is provided so that the contraction state is smaller than the assumed wearer's wrist. Is preferable, and a higher fit can be obtained when worn.

  The plurality of convex portions 5 are formed over the entire palm region of the glove body 3. In the present invention, the convex portion 5 can be formed only in a part of the palm region, for example, can be formed only in the finger portion of the palm region, and other than the finger of the palm region. It is also possible to form only in the portion (flat portion of the palm region). Further, the plurality of convex portions 5 provided in the form of dots are arranged in a substantially uniform manner in the region where the convex portions 5 are formed (the entire area of the palm region).

  Each convex portion 5 is provided in a substantially circular granular shape when viewed from the front (when the palm region is viewed from the vertical direction). In the present embodiment, the convex portion 5 is provided with a diameter of about 2 mm, but the diameter of the substantially circular convex portion 5 is preferably 1.0 mm or more and 8.0 mm or less, and more preferably. Is from 1.5 mm to 5.0 mm. If it is smaller than the above lower limit value, it is difficult to obtain a sufficient grip force at the convex part 5, and if it is larger than the above upper limit value, the air permeability in the vicinity of the convex part 5 is lacking, and the wearer's hand is easily stuffy. Moreover, it is preferable that the area which the some convex part 5 occupies is 1% or more and 80% or less with respect to the area of the formation area of the convex part 5 (the whole area of a palm region), More preferably, 5 % Or more and 50% or less. This is because if it is smaller than the lower limit value, it is difficult to obtain a sufficient grip force in the convex portion 5, and if it is larger than the upper limit value, the breathability in the palm region is insufficient and the wearer's hand is easily stuffy.

  In addition, the convex portion 5 is formed in a substantially semi-elliptical shape in which a cross-sectional shape (a surface obtained by cutting the palm region in the vertical direction) becomes narrower from the root portion toward the tip (outer surface side). And the base part of the convex-shaped part 5 is impregnated in the surface layer of the glove body 3. Thereby, the convex part 5 is firmly fixed to the glove body 3, and the convex part 5 can be accurately prevented from being detached from the glove body 3 during use. In addition, in the base part of the convex part 5 of FIG. 3, only the convex part 5 is illustrated and the glove body 3 is not illustrated. However, in this root part, not only the convex part 5 but also the glove body 3 is not illustrated. The fiber is present, that is, the root portion of the convex portion 5 enters the gap between the fibers of the glove body 3. Moreover, it is preferable that the base part of the convex-shaped part 5 has impregnated 50 micrometers or more from the surface layer of the glove main body 3, More preferably, it is 100 micrometers or more. This is because if it is smaller than the above lower limit value, the glove body 3 cannot be firmly fixed. The upper limit is the thickness of the glove body 3. Moreover, the case where the base part of some convex-shaped parts 5 of the some convex-shaped parts 5 is not impregnated in the surface layer of the glove main body 3 as mentioned above may be sufficient. However, of the plurality of convex portions 5, more than half of the convex portions 5 provided on the portion corresponding to the phalange (finger and flat finger base portion) are impregnated into the surface layer of the glove body 3 as described above. It is preferable that

  Moreover, the said convex-shaped part 5 is formed in the hollow, and specifically, it is preferable that the cavity part 5a is formed in the convex-shaped part 5 inside. Note that the hollow portion 5a may be formed in all of the plurality of convex portions 5, or may be formed in only some of the convex portions 5. However, it is preferable that more than half of the plurality of convex portions 5 are formed hollow in a portion corresponding to the phalange.

  The convex portion 5 is provided so as to protrude from the outer surface of the coat layer 7. In the present invention, the convex portion 5 can be provided so as to be exposed through the outer surface of the coat layer 7, but in this embodiment, the outer surface of the convex portion 5 is coated as shown in FIG. Although the thin film of the layer 7 is covered, the convex portion 5 is in a state of protruding from the average interface on the outer surface of the coat layer 7. Here, the protrusion height of the convex portion 5 compared to the outer surface of the coat layer 7 is preferably 0.02 mm or more and 0.50 mm or less, more preferably 0.04 mm or more and 0.40 mm or less. If the value is smaller than the lower limit value, a sufficient grip force cannot be obtained in the convex portion 5, and if the value is larger than the upper limit value, the convex portion 5 is likely to be broken when the object is gripped. In addition, it is in the range which this invention intends also when some convex-shaped parts 5 are not projecting from the outer surface of the coating layer 7 among several convex-shaped parts 5. FIG. However, it is preferable that more than half of the plurality of convex portions 5 provided on the portion corresponding to the phalange protrude from the coat layer 7.

  Moreover, the convex part 5 is comprised from resin or rubber | gum, and is formed so that elastic deformation is possible. Here, the convex part 5 is formed by the liquid convex part forming material adhering to the outer surface of the glove body 3 in the form of dots and solidifying.

  Conventionally known resins or rubbers can be used as the material of the convex portion 5, for example, natural rubber, nitrile butadiene rubber, silicone elastomer, acrylic rubber, acrylic elastomer, polyurethane rubber, polyurethane elastomer, etc. Although possible, it is preferable to employ a synthetic resin such as a vinyl chloride resin. By adopting a synthetic resin such as a vinyl chloride resin in this way, the volume change before and after solidification in the forming process is less than that of latex rubber, etc. ) Can be easily and reliably adjusted, and manufacturing can be easily and reliably performed.

  Further, when a vinyl chloride resin is employed as the resin constituting the convex portion 5, a soft vinyl chloride resin can be employed, or a vinyl chloride resin or a vinyl chloride-vinyl acetate copolymer resin can be employed. Is possible. Specific examples of this resin include, for example, trade name PSM-30 (manufactured by Kaneka Corporation), trade name PSH-31 (manufactured by Kaneka Corporation), trade name PCH-843 (manufactured by Kaneka Corporation), and the like. .

  Moreover, it is also possible to mix | blend a conventionally well-known plasticizer, a stabilizer, a thickener, a pigment, etc. with the material of the convex-shaped part 5. FIG. Examples of the plasticizer include phthalate esters, adipate ester plasticizers, citrate ester plasticizers, benzoate ester plasticizers, polyester plasticizers, and acrylic copolymer plasticizers. .

  Moreover, it is preferable that the compounding quantity of a plasticizer is 90 to 180 mass parts with respect to 100 mass parts of resin, More preferably, it is 120 to 160 mass parts. If it is less than the above lower limit value, the convex part 5 becomes hard and sufficient gripping force by the convex part 5 cannot be obtained, and if it exceeds the above upper limit value, the convex part 5 becomes too soft and grips. This is because the convex portion 5 is likely to be broken during the operation.

  Further, the thickener is added to adjust the viscosity, and the viscosity of the material for constituting the convex portion 5 is V2 viscosity of 100,000 mPa · s or more and 1.5 million mPa · s or less in the BH type viscometer. It is preferable that it is 200,000 mPa · s or more and 1,000,000 mPa · s or less. If it is smaller than the above lower limit, the fluidity of the material becomes too high, and the convex portion 5 tends to become flat. On the other hand, if it is larger than the above upper limit value, bubbles are likely to be mixed into the material, and there is a possibility that a dent or the like may be inadvertently formed on the outer surface of the convex portion 5. In addition, when the masking plate provided with perforations in the portion corresponding to the convex portion 5 in order to dispose the material of the convex portion 5 in the form of dots in the glove body 3 is larger than the above upper limit value, The material of the convex portion 5 is difficult to flow into the perforations of the masking plate, and it may be difficult to form the desired convex portion 5.

  The coat layer 7 is laminated on the outer surface of the glove body 3 in a region other than at least the convex portion 5 of the palm region. In the present embodiment, the coat layer 7 is configured over the entire palm region including the convex portion 5. A liquid coat layer forming material is applied and formed by solidifying the material. In the illustrated example, not only on the palm region of the glove body 3 but also on the outer periphery of the back region (the region on the outer surface when the object is grasped and extending from the wrist to the fingertip) that is the back side of the palm region. 2 is formed as shown in FIG. 2, but the coat layer 7 is provided in a so-called spine shape that is not formed in the center of the upper region. In addition, although it is preferable that this coat layer 7 is not formed in the sleeve part 3a, even if the coat layer 7 is formed in the sleeve part 3a on a manufacturing process, it is in the range which this invention intends. For the purpose of protecting the hand, a coat layer may be provided from the fingertip to the indirect part of the base of the finger in the upper region.

  The coat layer 7 is provided in a porous state and has air permeability. Here, as the material constituting the coating layer 7, it is also possible to use mechanically foamed latex or vinyl chloride sol, or latex or vinyl chloride sol containing a chemical foaming agent. However, the mechanically foamed material has a high viscosity, the coat layer 7 becomes thick, and the convex portion 5 may be buried in the coat layer 7. Moreover, it is difficult to control the thickness of the foamed layer with a material containing a chemical foaming agent, and the convex portion 5 may be buried in the coat layer 7 as well. For this reason, it is preferable to employ a polyurethane solution for wet processing as the coating layer forming material. As a result, the desired coating layer 7 can be easily and reliably formed by dipping the polyurethane solution. That is, since the polyurethane solution for wet processing has a low viscosity, the coat layer 7 can be formed in a relatively thin layer, and the convex portion 5 is easily provided by protruding from the outer surface of the coat layer 7. When a polyurethane solution is used as the coating layer forming material, for example, a polyurethane resin for wet processing dissolved in DMF (N, N-dimethylformamide) can be used. For example, trade name Chris Bon 8006HVLD (manufactured by DIC Corporation) can be used.

  The coat layer 7 has an interface (outer surface) outside the outer surface (surface of the surface layer) of the glove body 3 in the region where the convex portions 5 are not formed (between the plurality of convex portions 5). It is provided to be located on the side. Specifically, the surface layer of the coat layer 7 located on the outer surface side of the outer surface of the glove body 3 is provided with a thickness of 0.23 mm (distance from the outer surface of the glove body 3 to the outer surface of the coat layer 7), for example. Yes. In addition, it is preferable that the thickness of the surface layer of this coat layer 7 is 0.05 mm or more and 0.80 mm or less, More preferably, it is 0.10 mm or more and 0.40 mm or less. This is because if it is thinner than the lower limit, it is difficult to form the surface layer of the coat layer 7, and if it is thicker than the upper limit, the wearer may be worried.

  Moreover, the coat layer 7 is exposed and provided on the inner surface of the glove body 3 by being formed by impregnating the glove body 3 with the coat layer forming material. That is, the coat layer 7 is provided on the surface that comes into contact with the palm of the wearer. The material constituting the coat layer 7 is also impregnated on the inner surface side of the glove body 3 where the convex portion 5 is formed (just below the root portion of the convex portion 5).

  The coat layer 7 is provided in close contact with the outer periphery of the buried portion of the convex portion 5. Here, the buried portion of the convex portion 5 is a portion of the convex portion 5 located on the inner surface side of the surface layer of the coat layer 7 (a portion where the convex portion 5 does not protrude).

  In addition, a vinyl chloride resin or a vinyl chloride-vinyl acetate copolymer resin is adopted as a main component of the resin material constituting the convex portion 5, and polyurethane is adopted as a main component of the rubber material constituting the coat layer 7. As a result, the main material of the rubber component constituting the coat layer 7 is impermeable to the convex portion 5. For this reason, the coat layer 7 is difficult to be formed on the outer surface of the convex portion 5, and even if formed, a relatively thin film (coat layer 7) can be formed.

Further, in the anti-slip glove 1, the moisture permeability between the outer surface and the inner surface on the palm side is preferably 1000 g / m ² · 24 h to 15000 g / m ² · 24 h, more preferably 4000 g / m. It is m ² · 24 h or more and 12000 g / m ² · 24 h or less. If it is smaller than the above lower limit value, there is a problem that the palm will be steamed if the wearer wears it for a long time, and if it is larger than the above upper limit value, the coat layer 7 becomes insufficient and sufficient grip force cannot be obtained. In addition, the said moisture permeability is a numerical value measured by JIS-L-1099A method (The moisture permeability test method of a textile product).

  In the non-slip processed glove 1 of the present embodiment having the above-described configuration, the convex portion 5 protrudes from the outer surface of the coat layer 7. Grip force acts accurately. In particular, since the convex portion 5 is provided so as to be elastically deformable, the convex portion 5 is accurately deformed during gripping, and this deformation increases the contact area between the portion of the convex portion 5 and the object to be grasped, Sufficient grip will be obtained. And since the convex-shaped part 5 is formed in hollow, the said deformation | transformation will occur easily more and it can obtain more sufficient grip force.

  Further, since the material constituting the coat layer 7 is impermeable to the convex portion 5, the coat layer 7 is hardly formed on the outer surface of the convex portion 5. For this reason, the coat layer 7 is not formed on the outer surface of the convex portion 5, or even if it is formed, the coat layer 7 is relatively thin. Therefore, when the object to be grasped is grasped, the convex portion 5 is accurately deformed. Easy and sufficient grip. Further, when the coat layer 7 is not formed on the outer surface of the convex portion 5, the object to be grasped and the convex portion 5 are in direct contact with each other, and the material (resin) constituting the convex portion 5 and the material to be covered are covered. A frictional force (grip force) is obtained between the gripped object and the object. Further, even when the thin coat layer 7 is formed on the outer surface of the convex portion 5, the coat layer 7 at this portion is thin, so that it may be peeled off during use and the convex portion 5 is exposed. As a result, a frictional force is obtained between the material constituting the convex portion 5 and the object to be grasped as described above. For this reason, the frictional force by contact with the raw material of the convex part 5 different from the coat layer 7 is obtained, and an accurate gripping force can be exhibited against various objects to be grasped.

  In addition, it is generally considered that the coating layer 7 is made of the same material as the convex portion 5 or a material that is easily fixed to the convex portion 5 so that the convex portion 5 is not detached. However, when the coat layer 7 and the convex portion 5 are made of the same material, the coat layer is formed thick on the outer surface of the convex portion 5, and the convex portion 5 is buried in the coat layer 7. Cheap. In particular, when the coat layer 7 is provided in a porous state, the coating layer forming material has a high viscosity, so that the convex portion 5 is easily embedded in the coat layer 7 as described above. For this reason, the configuration in which the convex portion 5 protrudes from the coat layer 7 as in the anti-slip processing glove is an epoch-making configuration, and this configuration has an effect that an accurate grip force can be exhibited.

  Furthermore, since the base part of the convex part 5 is impregnated in the surface layer of the glove body 3, the convex part 5 is firmly fixed to the glove body 3, and the convex part 5 is detached from the glove body 3 during use. Can be accurately prevented. In particular, since the coat layer 7 is provided in close contact with the outer periphery of the buried portion of the convex portion 5, the detachment of the convex portion 5 can be prevented more accurately. Thus, since the convex part is firmly fixed to the glove body, the convex part is unlikely to be detached from the anti-slip glove, so that the grip force is not easily lowered even when used for a long time.

  In addition, since the coat layer 7 surrounds the outer periphery of the embedded portion of the convex portion 5 in this way, the convex portion 5 faces one end side of the fabric of the glove body 3 when the object to be gripped is gripped. While pulling up to the side, it is possible to regulate the movement of the root portion escaping from the palm of the wearer. That is, when the convex portion 5 is simply provided on the glove body 3 without providing the coat layer 7, a force is applied to the convex portion 5 in the palm plane direction (for example, fingertip direction) when the object to be grasped is gripped. If it acts, the convex part 5 will pull the one end side (sleeve side) part of the glove body 3 to be fixed to the outer surface side and the base part of the convex part 5 will move away from the palm. The force may not work. On the other hand, the anti-slip glove 1 is provided with the coat layer 7 in close contact with the outer periphery of the embedded portion of the convex portion 5, and the coat layer 7 is provided as compared with the case of the mere glove body 3. Since the obtained glove body 3 has high rigidity, the glove body 3 and the portion on one end side of the coat layer 7 are not easily pulled up to the outer surface side, and thus an accurate grip force can be exhibited. In particular, since the coat layer 7 is also formed on the inner surface of the glove body 3 where the convex portion 5 is formed (just below the root portion), the coat layer 7 not only surrounds the convex portion 5 but also the inner surface (lower surface). ), The separation of the convex portion 5 from the palm as described above can be prevented more accurately, and the gripping force can be exhibited accurately.

  The outer surface of the glove body 3 is provided with a coat layer 7 in a region other than the convex portion 5, and the fibers of the glove body 3 are not exposed. The gripping object can be securely gripped.

  Further, since the coat layer 7 is exposed on the inner surface of the glove body 3, a sufficient frictional force acts between the inner surface of the anti-slip glove 1 and the wearer's palm to grip the object to be gripped. In this case, it is possible to accurately prevent the non-slip processed glove 1 from slipping from the hand.

  Moreover, since the coat layer 7 has air permeability, the wearer's palm is hard to be stuffy, and in particular, since the coat layer 7 is formed in a spine shape, the wearer's hand is hardly stuffy.

  Next, although the manufacturing method of the anti-skid gloves 1 of the present embodiment having the above-described configuration will be outlined, the manufacturing method of the present invention is not limited to this. Moreover, in the following description of the manufacturing method, when it overlaps with the description of the non-slip glove, the description may be omitted.

  The manufacturing method of the present embodiment includes a glove forming step S1 for forming a fiber glove body 3 that covers a wearer's hand, and a convex portion forming material mainly composed of a resin in the palm region of the formed glove body 3. The coating layer 7 is formed so that the outer surface (average interface) is lower than the convex portion 5 in the palm region of the glove body 3 on which the convex portion 5 is formed, and the convex portion forming step S2 in which the convex portion 5 is formed. And a coating layer forming step S3 to be formed.

  The glove forming step S1 is a step of forming the glove body 3 by knitting into a glove shape with fibers made of woolly nylon or the like.

  In the convex portion forming step S2, a masking plate is placed on the palm region of the glove body 3 formed in the glove forming step S1, and the material constituting the convex portion 5 is filled in the perforations provided in the masking plate. Then, the glove body 3 is attached to the glove body 3, and then the masking plate is detached from the palm region of the glove body 3, and the glove body 3 to which the material of the convex section 5 is adhered is heated to attach the convex section 5 to the glove. This is a step of obtaining the main body 3. When the masking plate is lifted upward so as to be detached from the palm region of the glove body 3 as described above, first, the convex portion 5 that is in contact with the inner surface of the perforation in the material of the convex portion 5 inside the perforation of the masking plate. The outer peripheral portion of the convex portion 5 is lifted upward together with the masking plate, and further the masking plate is lifted, so that the outer peripheral portion of the convex portion 5 is detached from the masking plate. As a result, the outer peripheral portions are united to form the hollow portion 5 a inside the convex portion 5.

  The coat layer forming step S3 is applied to the glove body 3 and the glove body 3 is coated with a coat layer material application step S31 for applying a coat layer forming material containing a main component resin or rubber and a solvent. And a porous step S32 for extracting the solvent of the coating layer forming material.

  The coat layer material application step S31 is a step of covering the glove body 3 in a three-dimensional shape and immersing the palm region of the glove body 3 in the coat layer forming material.

  In the porous step S32, the glove body 3 is bathed in hot water for a predetermined time or more to replace the solvent with water in the coat layer forming material that has penetrated into the glove body 3, and then dried to make the coat layer 7 porous. It is a process of quality improvement.

  According to the said method, the said anti-skid glove 1 which has the said advantage can be manufactured.

  In addition, this invention can be implemented in the aspect which gave various change and improvement other than the said aspect.

  That is, in the said embodiment, although the point-shaped thing was demonstrated as the convex part 5, the shape of the convex part 5 is not specifically limited, It is employable for the convex part 5 of various shapes. For example, as shown in FIG. 7, it is within the range intended by the present invention to provide a plurality of elongated thin convex portions 5.

  Further, as described above, the material constituting the convex portion and the material constituting the coat layer are preferably selected so that the material forming the coat layer is impermeable to the convex portion. . Specifically, when a vinyl chloride resin is employed as the material constituting the convex portion, it is preferable to employ polyurethane rubber or polyurethane elastomer as the material constituting the coat layer. When a silicone elastomer is employed as the material constituting the convex portion, it is preferable to employ polyurethane rubber, polyurethane elastomer, natural rubber or nitrile butadiene rubber as the material constituting the coat layer. Furthermore, when natural rubber is employed as the material constituting the convex portion, it is preferable to employ polyurethane rubber, polyurethane elastomer or nitrile butadiene rubber as the material constituting the coat layer.

  Hereinafter, the present invention will be described more specifically with reference to examples. However, the present invention is not limited to the following examples.

Example 1

It was 700,000 mPa · s as measured with a BH viscometer (manufactured by TOKIMEC INC. (Currently Toki Sangyo Co., Ltd.)).

  A polyurethane resin for wet processing (trade name Crisbon 8006HVLD (manufactured by DIC Corporation)) was dissolved in DMF to prepare a coating layer forming material. The coating layer forming material was adjusted so that the concentration of the solid component was 10% by mass.

  A glove body was produced by knitting 280 denier wooly nylon using a 13 gauge glove knitting machine (trade name N-SFG (manufactured by Shima Seiki Co., Ltd.)).

  The glove body was placed in a flat shape, and a masking plate was placed on the upper surface of the glove body. As the masking plate, one having a thickness of 0.50 mm, a plurality of perforations, and an inner diameter of each perforation of 2 mm was used. And the said convex-part formation material was supplied from the upper surface of the masking board, and the convex-part formation material was filled into the perforation of the masking board. Specifically, the convex portion forming material was placed on the upper surface of the masking plate, and the convex portion forming material was poured into the perforations with a spatula. Thereafter, the masking plate was lifted upward and detached from the upper surface of the glove body. Then, by heating the flat mold at 180 ° C. for 10 minutes, the convex portion forming material adhering to the glove body in a scattered manner was solidified to form the convex portion.

  And the glove body in which the convex part was formed was removed from the flat mold, and this glove body was attached to a three-dimensional mold and immersed in the coating layer forming material. This dipping operation was performed so that the palm region of the glove body was immersed in the coating layer forming material, and the back region of the back surface of the palm region was not immersed as much as possible. Thus, the glove body in which the coating layer forming material penetrated into the palm region was immersed in a 50 ° C. water bath for 40 minutes. And after drying this glove main body for 30 minutes at 120 degreeC, the glove was extracted from the hand type | mold, and the non-slip processed glove of Example 1 was produced.
