Description

  The present invention relates to a non-slip glove used in a field where grip properties are required.

Conventional gloves used in fields that require grip, such as assembly work and packing work, are made of synthetic rubber on the surface of fiber gloves made of natural fibers such as cotton and chemical fibers such as acrylic, polyester, and nylon. Those coated with natural rubber, polyvinyl chloride or the like are generally used. Using a rubber thread inserted into the wrist to improve fit and prevent slipping off (Patent Document 1), or using a glove base fabric, on the resin part formed on the outer surface There are some which exhibit the anti-slip effect by giving the same uneven shape as the uneven stitches of the fabric (Patent Document 2).

  However, as described above, a glove which forms a rubber or resin film on a fiber glove base material to prevent slipping has a problem that the greater the anti-slip effect of the film, the easier the hand slips on the inner surface of the glove.

  The present invention solves the above-described problems, and an object thereof is to provide an anti-slip glove that has a large anti-slip effect when grasping an object and that is hard to slip on the inner surface of the glove.

  In order to solve the above problems, the anti-slip glove of the present invention is characterized in that a foamed film of rubber or thermoplastic resin is formed on a fiber glove base material knitted with elastic fibers and non-elastic fibers. .

  Elastic fibers and non-elastic fibers are preferably used as 50d to 600d yarns. Moreover, it is preferable that the fiber glove base material (hereinafter referred to as fiber glove) is knitted using the elastic fiber in a ratio of 5 to 80% by mass as a whole or a finger part. As a result, the fiber glove has excellent followability, and even when the object is grasped, the hand does not slip on the inner surface of the glove, and the force of the hand can be efficiently transmitted to the glove. A foamed film of rubber or thermoplastic resin The performance of the film having a very large anti-slip effect can be exhibited sufficiently. It is appropriate to use such a fiber glove when the foamed film has a dynamic friction coefficient μK of 1.0 or more. The coefficient of dynamic friction is used as an index of the difficulty of slipping. The larger the value, the less slippery and the better the grip.

  It may be a filament yarn or a spun yarn. The thickness (fineness) is represented by “d” for the filament yarn and “count” for the spun yarn. In the present invention, the spun yarn or the like is also expressed in terms of denier. When the thickness is within the above range, the fiber gloves become thin, and the workability is good with a bare skin feeling. If it is thinner than this range, the glove cannot be knitted.

  As the elastic fiber, a fiber having a recovery property of 100% or more when stretched at 100% can be suitably used. For example, a polyurethane fiber having an elongation of 400-800% and a fineness of 15d to 500d can be used. . Polyurethane fibers having a fineness of 15d to 40d are preferred. The elastic fiber may be covered with a non-elastic fiber and used as a composite yarn.

  As non-elastic fibers, natural fibers such as cotton and wool and chemical fibers such as polyester and nylon may be used alone, or these natural fibers and chemical fibers are mixed with aramid, reinforced polyethylene, metal, carbon, etc. It may be used as a composite yarn. Those having low dust generation properties are preferred.

  Rubber used for forming the film is natural rubber, isoprene, chloroprene, acrylic ester, styrene-butadiene copolymer, acrylonitrile-butadiene copolymer, polyurethane, butyl rubber, polybutadiene rubber, silicone rubber, 10% by weight or less. These copolymers having a carboxyl-modified group or the like, or blends thereof.

  The term natural rubber includes not only natural rubber alone but also natural rubber-methyl methacrylate copolymer, epoxidized modified natural rubber copolymer and the like. The terms acrylic ester (rubber) are n-butyl acrylate, n-butyl methacrylate, iso-butyl acrylate, iso-butyl methacrylate, ethyl acrylate, 2-ethylhexyl acrylate, 2-ethylhexyl methacrylate, iso-propyl acrylate, iso- In addition to homopolymers or copolymers such as propyl methacrylate, copolymers containing acrylonitrile, methyl methacrylate, allyl methacrylate, N-methylolacrylamide, acrylic acid, methacrylic acid and the like are included.

  A well-known cross-linking agent, vulcanization accelerator, anti-aging agent, thickener and the like are added to the rubber. Further, in order to improve the grip strength, a foaming agent and a foam stabilizer are added to make the film into a foam structure, and mechanical foaming is preferably used in combination. As the foaming agent, alkyl monoamide disodium sulfosuccinate, potassium oleate, castor oil potassium, and sodium dodecylbenzenesulfonate can be used. As the foam stabilizer, ammonium stearate, peptide, alkyl dipropionate soda and the like can be used. Alkyl here is, for example, lauryl, octyl, stearyl. In addition, since the component distinction of a foaming agent and a foam stabilizer is generally not exact | strict, it may be what is called by any name.

  The thermoplastic resin used for forming the film is, for example, a vinyl chloride homopolymer or a copolymer with vinyl acetate. Add known plasticizers, stabilizers, thickeners and the like. Chemical foaming agents and microcapsules such as toluenesulfonyl hydrazide, PP'oxybis (benzosulfonylhydrazide), azodicarbonamide, azobisisobutyronitrile are used when thermal expansion is used to make the film into a foam structure. it can. A silicone-based foam stabilizer may be added for mechanical foaming.

Particles such as acrylic, urethane, natural rubber powder, EVA powder, PVC, NBR, talc, and calcium carbonate may be further added to the thermoplastic resin or rubber.
In order to form a film of these thermoplastic resins or rubber on a fiber glove, the fiber glove is put on a hand mold, a rubber compound or a thermoplastic resin compound is adhered by a method such as immersion or screen printing, and then cured. To do.

  The anti-slip glove of the present invention is produced by mixing a fiber glove base material, which is provided with a very anti-slipping film called rubber or thermoplastic resin foam film, by mixing elastic fibers. The hand does not slip on the inner surface of the glove, and on the contrary, the hand force can be efficiently transmitted to the glove, and the anti-slipping effect of the foamed film can be sufficiently exhibited. Therefore, grip properties are good.

Embodiments of the present invention will be described below. However, the present invention is not limited to the following embodiments.
When producing an anti-slip glove having a rubber film, the above-mentioned fiber glove composed of elastic fiber and non-elastic fiber is put on a hand mold, dipped in a calcium nitrate solution, and then dipped in a rubber compound. After drying for 10-20 minutes, a film is formed by curing at 120-130 ° C. for 40-60 minutes. A laminated film may be formed by immersing several times in a rubber compound having the same composition or a different composition. Reaching may be performed before or after curing. A thermal dipping method without using a calcium nitrate solution can also be used.

  When producing a non-slip glove having a film of thermoplastic resin, cover the above-mentioned fiber glove composed of elastic fiber and non-elastic fiber on a flat shape, and attach a resin compound on the surface in a convex shape by screen printing, A film is formed by curing at 110-150 ° C. for 10-20 minutes. It is also possible to use a method of forming a film by putting a fiber glove on a hand mold, immersing it in a thermoplastic resin compound, and curing it at about 190 ° C. for about 10 minutes.

Any film has a foamed structure (foamed layer), whereby the gripping force is improved and the dynamic friction coefficient μK becomes 1.0 or more. When heat-pressed, the grip effect is further improved. A heat press is a state in which rubber or a thermoplastic resin is slightly heat-set to be semi-crosslinked and gelled, using a metal or synthetic resin uneven plate, press pressure: 1 to 100 kgf / cm ² , Heat: It means to heat and solidify by applying about 60 to 300 ° C., resulting in a concavo-convex pattern. Although the film may have a laminated structure as described above, forming the foamed film directly on the fiber glove has a large anti-slip effect on the inner surface.

The bubble content of the compound at the time of foaming can be arbitrarily adjusted from 1% to 300% by a home mixer or a foaming machine. The bubble content can be measured by specific gravity, and the bubble content of the compound and the bubble content of the foamed layer after molding are almost the same value. It is preferable that 10 to 130 bubbles (or bubble marks) having an average diameter of 10 μm to 400 μm are included in the inner surface and the surface of the foamed layer per 1 cm ² . Rather than using only a chemical foaming agent, the number of bubbles increases when mechanical foaming is also used, and many bubble marks are opened on the surface of the foam layer. When there are many bubble traces, water and oil intervening between the glove surface and the object are absorbed and eliminated in the bubble traces, so that the anti-slip effect is more excellent.

  If hot pressing is performed with the concavo-convex plate as described above, the bubbles pressed by the convex portions of the concavo-convex plate are crushed to cause heat fusion, and the wear resistance strength is increased. The larger the number of bubbles, the greater the number of bubbles that are thermally fused. When the heat-sealed state is confirmed by a microscope, the bubble content in the concave portion of the foam layer is compressed to 10% to 90% of the bubble content in the convex portion. This heat-sealed state depends on the unevenness of the uneven plate and the pressing pressure. In order to increase the wear resistance strength, the surface of the foamed layer may be lightly pressed even at the inner bottom surface of the concave portion of the concavo-convex plate, but in that case, the bubble marks on the surface of the foamed layer tend to disappear. If the concave portion of the concave and convex plate is made large so that the convex portion of the concave and convex plate presses the surface of the foam layer but the inner bottom surface of the concave portion does not press the surface of the foam layer, bubble marks on the surface of the foam layer will be generated. It is difficult to disappear and has an excellent anti-slip effect.

An example of a non-slip glove is shown in FIGS. In the figure, 1 is a fiber glove, 2 is a foamed film with irregularities formed by hot pressing, 3 is a pressed location, and 4 is a bubble (scratch).
Hereinafter, the present invention will be described based on specific examples.

Fiber gloves knitted from 20d polyurethane (elastic fiber) covered with 70d wooly nylon (non-elastic fiber) at 300 T / M and two wooly nylon 70d twin yarns (hereinafter referred to as first fiber) Gloves) were prepared. Also, a fiber glove made by knitting the whole with two woolly 70d twin yarns, and adding only one composite yarn covered with 300d / M of 70d wooly nylon with 20d polyurethane only on the fingers (hereinafter referred to as the second glove). Prepared fiber gloves). Moreover, the rubber compound of the following mixing | blending 1 was adjusted with the household automatic hand mixer so that bubble content might be 50%.

Put the first and second fiber gloves on the immersion mold, immerse each in a methanol solution of calcium nitrate, and immerse only the palm part (meaning one side including the finger part) in the rubber compound with 50% bubble content. The mold was released after heat setting at 75 ° C. for 10 minutes. Thereafter, one hand of the first and second fiber gloves was heat set at 120 ° C. for 20 minutes. The remaining one hand, the re put on the flat, 2 mm × 3 mm rectangle and a recess depth 0.5mm using an uneven plate was formed by 10 pieces / ^{cm 2,} 1kgf / cm ² on the palm, Hot pressing was performed at 180 ° C. for 5 seconds, and heat setting was performed at 120 ° C. for 20 minutes. It was confirmed by specific gravity measurement that the bubble content of the formed foamed film (one hand that was not hot pressed or the part that was not pressed during hot pressing) was equivalent to that of the compound.
(Example 2)

(Comparative Example 1)
A glove with a foam coating was prepared in the same manner as in Example 1 using a fiber glove knitted with two woolly 70d twin yarns and one 70d single yarn. However, the rubber compound of Formula 1 was prepared with a bubble content of 0% and 50%. The film was formed on the palm.
(Comparative Example 2)
A glove with a foam coating was produced in the same manner as in Example 1 using a fiber glove knitted with two 20th-hand cotton yarns. However, the rubber compound of Formula 1 was prepared with a bubble content of 0% and 50%. The film was formed on the palm.
(Evaluation)
Wearing each of the foam-coated gloves prepared in Examples 1 and 2 and Comparative Examples 1 and 2 and pulling the hand along the plate surface while pressing against the stainless steel plate with a constant load (about 3 kg), the inner surface of the glove Hand slip was evaluated. The results are shown in Table 1. Symbols in the table indicate ◎: not slipping at all, ○: not slipping, Δ: sliding slightly, ×: sliding.

  In addition, a test piece (63.5 mm × 63.5 mm) was cut from each palm part (portion with the foam coating) of the gloves with foam coating prepared in Examples 1 and 2 and Comparative Examples 1 and 2, and the coefficient of dynamic friction μK was obtained. Asked. This method is based on ASTM D1894. A test piece is attached to the moving weight of the friction coefficient measuring apparatus, the moving weight is run on a stainless steel plate at a moving distance of 130 mm at 150 mm / min, and the load therebetween is measured. The running resistance (dynamic friction coefficient) generated by the friction between the test piece and the stainless steel plate is calculated by the following equation. The results are shown in Table 1. It is evaluated that the larger the value of the dynamic friction coefficient, the greater the anti-slip effect of the rubber or thermoplastic resin film.

μK (coefficient of dynamic friction) = C / D
Here, C is the average load value (g) after the uniform running, and D is the mass 200 (g) of the moving weight.

上記の＜表１＞に示した比較例１、比較例２の結果から、使用したコンパウンドが同じときには、気泡含有量が多い方が動摩擦係数が大きくなり、気泡含有量も同じであれば熱プレスありの方が動摩擦係数が大きくなること、また動摩擦係数が大きいほど手袋内面で手が滑りやすいことがわかる。

From the results of Comparative Example 1 and Comparative Example 2 shown in <Table 1> above, when the compound used is the same, the larger the bubble content, the larger the dynamic friction coefficient, and the same bubble content, the hot press It can be seen that there is a larger coefficient of dynamic friction, and that the greater the coefficient of dynamic friction, the easier the hand slips on the glove inner surface.

  In Example 1 in which a foamed film was formed with the same compound (rubber) and bubble content (50%) as in Comparative Examples 1 and 2, the dynamic friction coefficient was almost the same as in Comparative Examples 1 and 2, but the hand on the inner surface of the glove The anti-slip effect is greatly improved by mixing elastic fibers with fiber gloves.

  In Example 2 in which a foamed film was formed of a compound (thermoplastic resin) different from Comparative Examples 1 and 2 and Example 1, the dynamic friction coefficient was that of the bubble content (50%) of Comparative Examples 1 and 2 and Example 1. Although it is somewhat smaller than that of Comparative Example 1 and 2, it is sufficiently larger than that of Comparative Example 1 and 2 (0%), but the hand does not slip on the inner surface of the glove, and elastic fibers are mixed into the fiber glove. The anti-slip effect is greatly improved.

  The anti-slip glove of the present invention is particularly useful for use in fields where gripping properties are required.
