Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a glove with a functional hook-and-loop fastener that prevents slipping during wearing and prevents liquids such as water from entering the inside of the gloves during work. The present invention also relates to a method for manufacturing gloves with hook-and-loop fasteners that can be attached at low cost.

[0002]

2. Description of the Related Art Conventionally, a hook-and-loop fastener is adhered to the hem of household rubber gloves, and the hem of the glove is tightened according to the size of the wrist or arm to prevent water from entering the gloves during work. I'm out. For example, Japanese Patent Laid-Open No. 10-60713
In the gazette, a rubber glove is provided with a belt and a belt fitting,
A method is disclosed in which a belt fastener is passed through the belt metal fitting and a hook-and-loop fastener is adhered to the joint between the belt tip and the belt, and the mouth of the rubber glove is fastened with the belt after wearing the glove.

Further, in Japanese Utility Model Laid-Open No. 58-143817, a band-shaped stop band having a male portion of a surface fastener attached to one end is attached to one of the cuff portions of a glove, and a female portion of the surface fastener is attached to the other. A household glove with a cuff that can be tightened is disclosed.

Further, Japanese Utility Model Registration No. 3051667 discloses a method in which the insertion opening of the rubber glove is made slightly longer and wider than that of the conventional product, and a one-touch tape is attached, where it is tightly fixed to the arm.

In these conventional techniques, the gloves and the surface fastener are fused and joined by ironing or high frequency welding. Further, among the surface fasteners commercially available, there are those in which an adhesive is applied to the back side of the surface fastener in advance, or a material which can be adhered to an adherend with an iron or a high frequency welder is used. It is difficult to obtain sufficient mechanical strength when heat-sealed in such a technique.

Further, the high-frequency welding process is an adhesive technique which is frequently used for thermoplastics, but a natural rubber or synthetic rubber material cannot provide sufficient adhesive strength. Furthermore, in the pasting with the conventional high-frequency welder, it is necessary to pay attention to the safety management and the problem of radio interference.

Further, since the processing method is based on the dielectric heating principle, applicable materials are limited, and it is not suitable for natural rubber or synthetic rubber materials. A double-sided adhesive tape, which is used as a pressure-sensitive adhesive attached to the backside of the fiber, can also be used, but in this case it has only the adhesive strength of cellophane tape and has a long-lasting storage, washing and adhesive effect. I can't get enough.

In particular, as the thickness of the gloves increases, heat transfer is inferior due to the method using an iron or a high-frequency welder, and it cannot be manufactured or problems such as peel strength and running cost occur.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is a glove made of a soft material such as rubber having a hook and loop mixed type self-bonding surface fastener adhered to the hem portion of the glove. These are gloves with hook-and-loop fasteners that allow you to freely adjust the tightening condition of the hem, prevent slippage with one touch, improve fit and prevent water from entering.

FIG. 1 shows a schematic view of a glove with a surface fastener of the present invention. In the figure, the glove 1 has an elongated surface fastener 2 bonded to the hem portion of a glove body 3 made of a soft material along the glove inlet surface. After wearing the gloves with hook-and-loop fastener, as shown in FIG.
By partially folding back the hem part and joining the surface fasteners to each other, it is possible to fit the glove to the size of a wrist or an arm and prevent water from entering the glove from the outside during water work.

Here, the gloves are made of natural rubber, silicone rubber, urethane rubber, nitrile rubber, vinyl chloride, acrylic rubber, chloroprene rubber, butadiene rubber, styrene-butadiene rubber, polyethylene and other general soft materials, or these materials. A mixture is used. It is preferable that the 300% modulus of this soft material is 10 MPa or less. 300% modulus is 10
When it exceeds MPa, the fit property is poor, and it becomes difficult for the glove to follow the movement of the hand during work. Preferably, the soft material has a 300% modulus of 7 MPa or less.

In the present invention, the hook-and-loop mixed type self-joinable hook-and-loop fastener is used as the hook-and-loop fastener. FIG. 3 is a perspective view of a hook / loop mixed type surface fastener used in the present invention. The surface fastener 11 has a hook-shaped engagement element 13 and a loop-shaped engagement element 14 provided on a surface 12 of a base material 15 made of woven cloth, knitted cloth, resin sheet or the like. As the base material 15 made of woven cloth, knitted cloth, and resin sheet, one having a thickness of 0.2 to 2.5 mm is usually used. As shown in the drawing, the hook-shaped engaging elements 13 and the loop-shaped engaging elements 14 are provided in a row on the surface of the base material.
The columns 3 and 14 can be provided alternately in every one row or every two rows. When forming the hook-shaped engaging elements 13, it is usually preferable to provide the hook engaging elements 13 in two rows from the viewpoint of easy cutting of the loops or easiness of planting on the resin sheet. The hook engaging elements 13 and the loop engaging elements 14 may be arranged in parallel with each other in the longitudinal direction of the base material shown in FIG. 3 in addition to parallel arrangement, for example, parallel arrangement or staggered arrangement along the longitudinal direction of the base material. Various arrangements such as a circular arrangement can be adopted. Particularly, the parallel arrangement along the longitudinal direction of the substrate is the simplest in manufacturing.

Polyamide resin and polyester resin are most suitable for the base material 15 of the surface fastener. Further, it is also possible to use those having improved rigidity by reinforcing these resins with carbon fibers, aramid fibers, inorganic fibers and the like. On the other hand, in order to impart flexibility to the base material 15 of the one-sided fastener, a predetermined amount of a plasticizer may be mixed with the nylon resin or the polyester resin of the base material. The shape of the hook-shaped engaging element may be a corrugated shape, a barbed shape, or a partial loop shape. The dimension of the surface fastener may be, for example, 10 to 100 mm in width and 10 to 200 mm in length.

In the present invention, a cyanoacrylate adhesive is used to bond the glove body and the surface fastener.
Here, cyanoacrylate adhesives are trade names of Aika Aibon N-1092 (Aika Kogyo Co., Ltd.), Arteco M, MR, MX, W1000X (Arteco Co., Ltd.), Super Alpha (Oshika Shinko Co., Ltd.), and Quick Bond (Kansai Polymer Research Co., Ltd.). ), ThreeBond (ThreeBond), Cemedine, and Cemedine3000 (Cemedine), ThreeBond (ThreeBond), Aron Alpha (Toagosei), CyanoBond (Taoka Chemical Co., Ltd.), Hard Rock (Denki Kagaku Kogyo), etc. .

When the surface fastener is adhered to the gloves,
The adhered portion of the glove surface may be previously combined with conventional surface treatment techniques such as molten metal sodium, corona discharge, glow discharge, and plasma irradiation.

In the present invention, the step of adhering the surface fastener to the hem of the glove includes the following steps. (1) A cyanoacrylate adhesive is applied to the back surface of the base material of the hook-and-loop fastener. Here, the cyanoacrylate adhesive is usually applied to a thickness of 1000 μm or less. For example, a method of arranging a plate having a groove on the back surface of the base material of the hook-and-loop fastener and pouring the adhesive into the groove of the plate, or putting the adhesive in the syringe and pushing it out from the outlet of the syringe tip by pressure Apply. Alternatively, the application can be performed using a dispenser device to which the adhesive is automatically supplied.

(2) The back surface of the men fastener is brought into contact with the hem portion of the glove made of a soft material having an elastic surface to adhere the hook fastener to the gloves. In the manufacturing method of the present invention, by adopting a cyanoacrylate-based adhesive that has been conventionally unsuitable for adhesion to a soft material for bonding a surface fastener, it is possible to dispense a low-viscosity adhesive with a dispenser or the like. The bonding process can be easily automated and the manufacturing can be performed at low cost.

Examples Example 1 and Comparative Example 1 A hook-and-loop fastener (manufactured by Kuraray Co., Ltd.) was bonded to the hem portion of a medium-thick glove of Mamasayan under the trade name of Dunlop Home Products Co., Ltd. using Velcro (R). . Two types of adhesives shown in Table 1 were used. Example 1 is a cyanoacrylate, and Comparative Example 1 is a mixture of chloroprene rubber, phenol resin, cyclohexane, acetone and hexane. The evaluation of adhesiveness and the peel test were carried out by the following methods.

[0022]

[Table 1]

(1) Adhesion test The surface fastener was pulled by hand and observed for peeling with the surface fastener bonded to gloves. The case where the hook-and-loop fastener was peeled off was marked with X, and the case where it was not peeled off was marked with ◎.

(2) Peel Test A surface fastener having a width of 25 mm and a length of 150 mm was attached to a glove using the adhesive of Example 1. The bonded portion was 40 mm. Then, using a tensile tester, the sample was pulled at a pulling rate of 100 mm / min and the appearance of the TC peeled portion was observed. The aging conditions were 70 ° C. and 168 hours.

From Table 1, Example 1 had a sufficient peel strength before aging and maintained a satisfactory peel strength even after aging. On the other hand, in Comparative Example 1, sufficient strength for the peel test could not be obtained.

Example 2 When a surface fastener is bonded to a glove, a comb-shaped plate or a dispenser having a groove in advance is used, and the adhesive is poured into the groove to suppress variations in the amount of the adhesive and to efficiently apply the adhesive. . In particular, by applying a large amount of the adhesive, it was possible to suppress the phenomenon of suppressing the whitening phenomenon, the economic effect, and the phenomenon that the adhesive layer was bent and cracked after curing and drying due to an excessive coating amount.
