Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work glove which can be used in a wide range of work such as housework, horticulture, light work such as handling precision parts, and cold work capable of withstanding use in extremely cold regions, and a manufacturing method thereof. In particular, a work glove and a work glove in which a foam layer of polyurethane resin is interposed between a glove material and a coating layer such as a synthetic resin or rubber covering the glove material to ensure flexibility suitable for the content of the work, and The present invention relates to a manufacturing method thereof.

[0002]

2. Description of the Related Art Conventionally, as is well known as a work glove, a surface layer of a fiber glove material is mainly coated with a coating material such as synthetic resin or rubber to improve oil resistance and durability. The gloves provided are widely adopted.

The work gloves of this type are coated with the above-mentioned coating material to increase the desired oil resistance, durability, etc.
Some of the synthetic resin itself of the coating material and additives, such as plasticizers, stabilizers, and viscosity modifiers, are adsorbed inside the threads of the glove material or penetrate into the space between adjacent threads. For this reason, there is a problem in that the flexibility of the work gloves configured is impaired, workability deteriorates, hand fatigue increases, and work efficiency decreases.

[0004]

As means for solving this problem,
Techniques for improving the composition of glove materials, coating materials, coating methods for coating materials, etc. have been developed. For example, Japanese Patent Publication Sho 58-4
In order to prevent the coating material from penetrating into the space between the adjacent fiber threads of the glove material, the method for manufacturing the work gloves related to No. 2281 requires the outer surface of the glove material to be repelled as a pre-process of the coating treatment. There is disclosed a processing technique for forming an oil repellent treatment layer that performs oil repellent treatment with an oil repellent agent such as a fluororesin or a silicone resin.

However, in the case of this processing technique, even if a fiber material having a uniform shape such as a cloth can be uniformly oil-repellent processed, a glove material such as a corner of a material or an overlapping material portion is used. It is difficult to apply uniform oil-repellent processing even to each part of the above, and if uneven processing is formed, there is a problem that the product becomes uneven, the product value decreases, and it becomes unusable.

In Japanese Patent Publication No. 4-7444, an acrylic emulsion or a urethane emulsion is applied to the outer surface of a glove body impregnated with a coagulant formed by dissolving an acid or the like and coagulated into a thin film. The first to dry this
Disclosed is a method for producing working gloves, which comprises a step and a second step in which a coating film of vinyl chloride paste is formed on the outer surface of a glove body and then cured.

However, this manufacturing method has the following problems. It is technically difficult to form a thin film of acrylic emulsion or urethane emulsion on the surface of the glove body. That is, low solids emulsions must be used to form thin films. If the solid content is low, the emulsion will penetrate between the fibers, and a thin film cannot be formed on the surface.In that case, the resin content will adhere to the periphery of the fibers, so a thin film will not be formed between the fibers. Instead, it becomes a hole-shaped blank part. For this reason, the emulsion capable of forming a film on the surface of the glove body has a high viscosity to some extent, the amount of adhesion increases, cannot be said to be a thin film, and its flexibility also deteriorates. In order to form a thin film using a coagulant, the adhesive strength between the thin film and the fiber is reduced, as in the above volatilization processing.
There is a problem of easy peeling. Even if the vinyl chloride paste coating and the thin film have good adhesion, the thin film and the glove body (fiber)
If there is a problem with the adhesiveness with, it will be difficult to achieve the purpose.

The present invention has been made from such a viewpoint, and an object thereof is to provide a working glove which can ensure particularly flexibility and has a low degree of fatigue, and a method for manufacturing the same.

[0009]

In order to achieve the above object, the working glove of the present invention has a foam layer of polyurethane resin formed so as to wrap a part or the whole surface of the glove material, and this foam is formed. It is characterized in that the surface of the body layer is coated with a coating layer such as synthetic resin or natural rubber.

Further, the glove material of the present invention is characterized by being a sewn or stretchable knitted glove made of a stretchable woven cloth, wherein the working gloves are outer gloves and are integrated inside the outer gloves. Alternatively, a sewn or stretchable knitted glove made of a detachable stretchable fabric may be configured as the inner glove.

Further, the method of manufacturing working gloves of the present invention is
A step of impregnating at least a part of the glove material with a polyurethane resin and foaming, and forming a foam layer of the polyurethane resin so as to include fibers of the glove material and between the fibers;
And a step of coating the surface of the foam layer with a coating layer such as synthetic resin or synthetic rubber.

[0012]

According to the work glove of the present invention, the fibers of the glove material are exposed to the outside due to the presence of the foam layer of the polyurethane resin in the foam state between and around the fibers of the glove material. The glove material itself does not lose its flexibility. When the surface of the foam layer in this state is coated with a synthetic resin or natural rubber coating material, the fibers of the glove material do not come into direct contact with the coating material, so that a working glove with high flexibility can be obtained.

Further, according to the production method of the present invention, the fibers of the glove material and the polyurethane resin are impregnated between the fibers, and this is foam-processed to form a sponge-like foam layer, which is adhered to the foam layer. Since it is sufficient to coat a coating layer such as vinyl chloride resin, which has good properties, peeling of the foam layer is eliminated,
In addition, the manufacturing method is simplified.
