Description

{GLOVE FOR FINGER AREA CUTTING PREVENTION}

The present invention relates to a glove for preventing cuts in the finger area, in which the glove lining is knitted with soft yarn, but cut-resistant yarn is applied only to the finger area where accidents occur most frequently.

In general, gloves are a means of protecting the wearer's hands, and include general gloves and coated gloves. Coated gloves are gloves that are knitted with various yarns (fibers such as nylon yarn, cotton yarn, or polyester yarn) and coated with latex (natural rubber latex, synthetic rubber latex, or other synthetic resin latex) to provide wear resistance, tear strength, puncture resistance, slip resistance, breathability, and waterproofing functions.

However, the above-mentioned general gloves or coated gloves generally have the disadvantage of having poor cutting strength or accident prevention functions (e.g., accidents caused by sickles or knives, etc.), and research and development to supplement this has been actively conducted recently.

More specifically, as in Patent Documents 1 to 3, general cut-resistant gloves are manufactured by knitting the glove lining using cut-resistant yarn (e.g., tungsten yarn, high performance polyethylene yarn, liquid crystal polyester yarn, Kevlar, etc.).

However, conventional cut-resistant gloves, such as the above, have problems in that the fit, feel, breathability, and coating properties are inferior to glove linings woven with general yarns because the entire inner lining of the gloves is woven using cut-resistant yarns, and the product cost and work fatigue increase.

Patent Document 1: Republic of Korea Patent Publication No. 10-1890566 “Method for manufacturing gloves using tungsten filament and gloves” Patent Document 2: Republic of Korea Patent Publication No. 10-0767452 “Working Gloves with Enhanced Cut Resistance” Patent Document 3: Republic of Korea Patent Publication No. 10-2010-0012668 "Foam gloves coated with water-dispersible polyurethane resin having excellent water repellency and method for manufacturing the same"

The present invention is to solve the above-described problems, and the object of the present invention is to knit the inner lining of a glove with soft yarn, while applying cut-resistant yarn only to the finger area where accidents occur most frequently, thereby maintaining the wearing comfort, touch, grip, agility, coating properties, etc. due to the use of soft yarn, and lowering the product cost and work fatigue, etc., while implementing excellent cut resistance, etc., for the finger area where accidents occur most frequently.

The present invention provides a glove for preventing cuts in the finger area, characterized in that the glove lining (10) is knitted with soft yarn, and the finger area (20) of the glove lining (10) is knitted with cut-resistant yarn, as a means for solving the problem.

In addition, the present invention provides a glove for preventing cuts at the finger portion, characterized in that the lining of the glove is coated with a polymer having a high coefficient of friction, as a means for solving the problem.

The present invention has the effect of implementing excellent cut resistance, etc. for finger areas where accidents frequently occur, while maintaining the wearing feeling, touch, grip, agility, coating properties, etc., and lowering the product cost and work fatigue, etc. In addition, in the present invention, when a metal thread such as tungsten is used for the glove lining, there is the effect of implementing a touch function that operates an electronic device screen even when the glove is worn. In addition, when the polymer coating is done in an open cell form with breathability, there is the effect of implementing breathability.

Figure 1 is a drawing showing the structure of a glove for preventing cuts on the finger part according to the present invention.
Figure 2 is a drawing for explaining the location of the ulnar metacarpal point and the ulnar metacarpal point among the finger parts.

In order to achieve the above effects, the present invention relates to a glove for preventing cuts on a finger portion. It should be noted that only the parts necessary for understanding the technical configuration of the present invention will be described, and the description of other parts will be omitted so as not to distract from the gist of the present invention.

Hereinafter, the gloves for preventing cuts on the fingers according to the present invention will be described in detail.

The gloves for preventing cuts in the finger portion according to the present invention are characterized in that the glove lining (10) is knitted with soft yarn, and the finger portion (20) of the glove lining (10) is knitted with cut-resistant yarn.

Meanwhile, a knitting machine such as a U3 (manufacturer: Shima Seiki) can be used to knit using different yarns only in specific areas as described above, but it is not necessarily limited to this, and various knitting machines capable of knitting with the above-mentioned structure can be used.

In other words, it is possible to maintain the fit, feel, grip, agility, and coating properties of soft yarns, while lowering the product cost and work fatigue, and at the same time implementing excellent cut resistance, etc. for the finger areas where accidents frequently occur.

Here, the finger part (20) is preferably a single part or two or more parts among the parts including the thumb, index finger, middle finger, radial metacarpal point (see FIG. 2) or ulnar metacarpal point (see FIG. 2), as shown in (a) to (d) of FIG. 1, and is not limited to the parts mentioned above, but refers to a region including a surrounding area of the parts mentioned above, but is not necessarily limited thereto, and can be applied to the part where accidents occur the most depending on the characteristics of various tasks.

Meanwhile, the above soft yarn usually means a fiber having an elastic modulus of 150 cN/dtex or less and having a characteristic of being easily deformed by an external tensile force. Nylon, which is a soft fiber, has an elastic modulus of about 30 to 50 cN/dtex, polyester fiber has an elastic modulus of about 80 to 100 cN/dtex, and acrylic fiber has an elastic modulus of about 30 to 40 cN/dtex. As soft fibers, synthetic fibers can be used alone or in combination in the form of filaments or spun yarns from crimped or elastic yarns of nylon yarn, PET yarn (polyethylene terephthalate yarn), PB yarn (poly butylene terephthalate yarn), acrylic yarn, PE yarn (polyethylene), PP yarn (polypropylene), various natural fibers (cotton, hemp, ramie, bamboo, silk, wool fibers, etc.) or various man-made fibers (for example, viscose rayon, tencel lyocell, spandex, etc.), but are not necessarily limited thereto, and various yarns already known can be applied depending on the type of work or usage environment.

And, the above-mentioned cut-resistant yarn is formed by covering a cutting-resistant fiber as a test piece, and the above-mentioned cut-resistant fiber means a fiber having an elastic modulus of 250 cN/dtex or higher and which is not easily deformed by an external tensile force. HPPE (high performance polyethylene yarn) has an elastic modulus of 800 to 1000 cN/dtex, steel yarn has an elastic modulus of 250 to 500 cN/dtex, and Kevlar and carbon fiber have an elastic modulus of 1000 to 2000 cN/dtex. As for the cut-resistant fibers, organic cut-resistant fibers include carbon yarn, HPPE, aramid fiber, and arylate fiber, inorganic cut-resistant fibers include glass fiber, ceramic fiber, and metal cut-resistant fibers include steel yarn, tungsten yarn, and the like. Aramid fibers include para-aramid (Kevlar), meta-aramid (Nomex), and copolymerized aramid (Technora). Gloves knitted with the above-mentioned cut-resistant yarns, alone or in a covering, have cut-resistant properties, and in cases where excellent cut-resistant performance is required, a glove lining having cut-resistant properties of A5, A7, or A9 (measurement method EN 388) or higher can be knitted. In the present invention, the cut-resistant yarn is formed by using a cut-resistant fiber alone or a cut-resistant fiber as a core material covered with a covering yarn, and the covering yarn may be formed by covering alone, or may be formed by first covering and second covering, wherein the first covering and second covering are formed in opposite directions.

Here, the cut-resistant fibers used for the above examination may be organic cut-resistant fibers such as HPPE, aramid, and allylate, metal cut-resistant fibers such as steel and tungsten yarns, etc., used alone or in combination or mixed with soft yarns, and the covering yarn may be used alone or in combination in the form of filaments, crimped yarns, spun yarns, etc. from nylon, PET, acrylic, HPPE (high performance polyethylene yarn), or aramid, but is not necessarily limited thereto, and various cut-resistant fibers and covering yarns already known may be applied depending on the type of work or the usage environment.

In addition, when forming the cut-resistant yarn applied to the finger area, if a metal thread such as tungsten is used as the test material, a touch function that operates the electronic device screen even when wearing gloves can be implemented.

And, the present invention can be manufactured in the form of a coated glove by coating a polymer or latex on the glove lining (10) formed as described above, and in this case, considering the coating property and functionality of the glove lining (10), a polymer having a higher slip resistance than the glove lining (10), that is, a polymer having a high coefficient of friction, is coated on the glove lining (10), and the high coefficient of friction means a polymer having a coefficient of friction of 0.5 to 3.0 (friction coefficient test method; ASTM D 1894-14, dry friction coefficient), and the polymer may be used alone or in combination from among natural latex, synthetic latex, polyurethane, PVC (polyvinyl chloride), silicone, acrylic, thermoplastic elastomer, rubber or polyolefin, and the polymer may be used in a state of solution or dispersion in water. In addition, the coating of the polymer as described above can be applied in a breathable open cell form by dipping, spraying, screen printing, injection or film bonding methods, but is not necessarily limited thereto, and various polymers and coating methods already known can be applied depending on the type of work or usage environment.

Here, in the case of the dipping, the glove lining (10) is immersed and dehydrated in a coagulating solution (for example, a coagulating solution optionally containing 3 to 25 parts by weight of calcium salt and 0.0001 to 1 part by weight of a wetting agent (nonionic/ionic or other silicone-based surfactant) for 100 parts by weight of water), and the glove lining (10) containing the coagulating solution is immersed in a polymer and dried to form a coating layer on the surface of the glove lining (10). At this time, when coating a polymer on the glove lining (10) containing the coagulant as described above, the glove lining (10) containing the coagulant may be dipped in a polymer containing a crosslinking agent (for example, NBR (nitrile-butadiene rubber) latex) and heat-treated, or the glove lining (10) containing the coagulant may be coated on a polymer in an aqueous dispersion state that does not contain a crosslinking agent, and the polymer used may contain 5 to 40 wt% of water-based polyurethane, but is not necessarily limited thereto, and various methods and polymers already known may be applied depending on the type of work or the usage environment.

Hereinafter, the contents of the present invention will be specifically described through the following examples, but the present invention is not necessarily limited to the following examples.
