BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing work gloves.

[0002]

2. Description of the Related Art Conventionally, in order to prevent the back of the hand of gloves made of cotton fiber or synthetic fiber (hereinafter referred to as raw fabric) made of knitted cloth from being covered, the raw fabric is placed in a raw material solution of a rubber latex compound. It is widely known that working gloves in which other parts are covered by being dipped are resistant to stuffiness even after long-term use.

Such work gloves are generally dipped in a raw material liquid of a rubber latex composition with the palm of the hand facing downward and the back of the hand facing upward while the raw hand is put on the hand, and then heated and pulled up. However, when the raw fabric is made of cotton fiber, the oil content is removed by bleaching so that the raw material liquid does not penetrate deeply into the fibers and reach the inner surface of the raw fabric. Water-repellent treatment is applied, and even in the case of synthetic fibers, the raw material liquid is soaked deeply between the fibers so that it does not reach the inner surface of the raw material. On the surface of the glove at the immersion boundary line located on the liquid surface of the raw material liquid, the adhering raw material liquid makes a wavy trace. That is, at the end of the raw material liquid coating part on the back side of the hand and the palm side where the liquid pressure of the raw material liquid is less likely to be applied, the raw material liquid is repelled and the adhesion of the raw material liquid to the raw hand is poor, and the rubber at the immersion boundary line during use However, there is a problem that it is easily peeled from the raw material.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve such a problem, and the adhesion of the raw material liquid to the raw material at the immersion boundary line located on the liquid surface of the raw material liquid where the liquid pressure of the raw material liquid is less likely to be applied. It is an object of the present invention to provide a working glove in which the rubber at the immersion boundary line is hard to be peeled from the raw hand during use.

[0005]

In order to solve this problem, the present invention provides a first step of bleaching a cotton fiber glove made of knitted cloth, and a water repellent treatment of the bleached glove with a water repellent. And a third step of applying a penetrant to the surface of the glove including the immersion boundary line on the liquid surface when the glove is dipped in the raw material liquid of the rubber latex compound in the subsequent step and hydrophilically treating it. The gist of the present invention is to provide a method for producing working gloves, which comprises a fourth step of immersing the above-mentioned gloves in a raw material liquid of a rubber latex compound and then heating and vulcanizing. The present invention also relates to a first step in which a synthetic fiber glove made of a knitted fabric is subjected to a water repellent treatment with a water repellent agent, and a liquid surface when the glove is immersed in a raw material liquid of a rubber latex compound in a subsequent step. The second step of applying a penetrant to the surface of the glove including the immersion boundary line to make it hydrophilic, and the third step of immersing the glove in the raw material liquid of the rubber latex compound and then heating and vulcanizing it The gist is the method of manufacturing work gloves.

[0006]

With this configuration, the cotton fiber gloves made of knitted fabric are chemically white with the bleaching agent to remove the colored substances. At the same time, the oil content contained in the glove is also removed, and the entire glove becomes hydrophilic. After that, by treating with a water repellent, the surface of the fiber depleted of oil is covered with the water repellent, and the hydrophilic property of the entire glove is lost. Further, synthetic fiber gloves made of knitted fabric are treated with a water repellent agent in the same manner as cotton fiber gloves, so that the fiber surface is covered with the water repellent agent. In the next step, by applying a penetrant to the surface of the glove including the immersion boundary line on the liquid surface when it is immersed in the raw material liquid of the rubber latex compound in the subsequent step and hydrophilically treating it, the fiber at the immersion boundary line The surface has hydrophilicity. After that, by immersing the glove in the raw material liquid of the rubber latex compound and then pulling it up and heating it to vulcanize, the adhesion of the raw material liquid to the glove is increased at the boundary between the portion where the raw material liquid adheres and the portion where the raw material liquid does not adhere, It is possible to provide a work glove in which rubber is unlikely to peel off from the boundary during use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the following examples, a cotton fiber raw material made of knitted fabric was dipped in a raw material solution of a rubber latex composition with the palm facing downward and the back of the hand facing upward while the hand was covered. Then, a method for manufacturing working gloves, which is made by pulling up, heating and vulcanizing, will be described.

First, the bleaching agent used in the first step of bleaching a cotton fiber raw material made of knitted fabric is an oxidative bleaching agent, 35% hydrogen peroxide 0.5% by weight, fluorescent dye 0. Three
Using a mixture of 1% by weight and 99.2% by weight of water, the mixed solution is heated to 80 ° C. and the cotton raw material is immersed for 20 minutes.

Second, the bleached raw material is treated with a water repellent agent for water repellent treatment.
Water repellents used in the process include metallic soap, silicone, paraffin emulsified oil, octadecyl ethylene urea, emulsions of polyhydric alcohol fatty acid ester, etc., one of which is dipped in water to mix the raw material. .

In the third step, the raw material after the water repellent treatment is applied to 80
It is dried at 60 ° C. for 60 minutes, and the original hand 1 is put on the hand mold 2 as shown in FIG. Then, in this third step, a penetrant is applied to the surface of the raw fabric 1 including the immersion boundary line on the liquid surface when the raw fabric 1 is immersed in the raw material liquid of the rubber latex compound in the subsequent process. An anionic surfactant (sodium dioctyl sulfosuccinate) is used as the penetrant, and a 1% aqueous solution is applied by spraying, and the prosthesis 1 is subjected to hydrophilic treatment. Specifically, the penetrant is applied to the back side of the proto-hand 1 in the range surrounded by the chain double-dashed line shown in FIG. 1, and the penetrant is applied to the vicinity of the wrist on the palm side.

In the fourth step, the stencil 1 is put on the hand mold 2 in a drying chamber to dry the penetrant adhering to the stencil 1, and the hand mold 2 is preheated to 80 to 100 ° C. Then
Then, as shown in FIG. 2, with the original hand 1 covered with the hand mold 2, the palm 3 faces downward and the back 4 of the hand faces upward.
It is dipped in the raw material liquid 5 of the rubber latex composition prepared at the mixing ratio shown in (1) and kept at about 30 ° C., and the raw material liquid is attached to the prosthesis 1 in the unlined state. After that, the raw fabric 1 is pulled up from the raw material liquid 5 and heated at a temperature of 100 to 120 ° C. to be vulcanized to complete the work gloves 6 shown in FIG. In FIG. 3, the shaded portion 7 is a rubber covered portion.

[Table 1] Natural rubber latex (solid content) 100 parts (weight) Stabilizer 0.3 part Sulfur 1 part Zinc white 1 part Vulcanization accelerator 1 part Anti-aging agent 1 part Pigment 1.5 parts Heat-sensitive gelling agent 1 By the way, in the above-mentioned examples, the bleaching process is performed by using the cotton fiber prosthesis made of the knitted fabric, but it is also possible to use the synthetic fiber prosthesis made of the knitted fabric. If you do not need to bleach. In the case of the synthetic fiber raw fabric, the fiber surface is covered with the water repellent by being treated with the water repellent as in the case of the cotton fiber raw fabric, and the same treatment may be performed thereafter.

[0013] Further, the raw material solution is soaked in the raw material liquid of the rubber latex compound so that the palm faces downward and the back of the hand faces upward while the raw hand is put on the hand mold. Although it is adhered, the same can be done when the raw material is dipped in the raw material liquid so that the fingertips face downward.

As the rubber latex used in the above embodiment, synthetic rubber may be used in addition to natural rubber.

[0015]

As described above, according to the present invention, a cotton fiber glove made of knitted cloth becomes a pure white because the colored substance is chemically removed by the bleaching agent. At the same time, the oil content contained in the glove is also removed, and the entire glove becomes hydrophilic. After that, by treating with a water repellent, the surface of the fiber depleted of oil is covered with the water repellent, and the hydrophilic property of the entire glove is lost. Further, synthetic fiber gloves made of knitted fabric are treated with a water repellent agent in the same manner as cotton fiber gloves, so that the fiber surface is covered with the water repellent agent. In the next step, by applying a penetrant to the surface of the glove including the immersion boundary line on the liquid surface when it is immersed in the raw material liquid of the rubber latex compound in the subsequent step and hydrophilically treating it, the fiber at the immersion boundary line The surface has hydrophilicity. After that, by immersing the glove in the raw material liquid of the rubber latex compound and then pulling it up and heating it to vulcanize, the adhesion of the raw material liquid to the glove increases at the boundary between the portion where the raw material liquid adheres and the portion where the raw material liquid does not adhere, It is possible to provide a work glove in which rubber is unlikely to peel off from the boundary during use.
