DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a working glove provided with a lining and a rubber or resin film, and a method for manufacturing the same.

[0002]

2. Description of the Related Art Work gloves generally have a lining and a rubber or resin film provided on at least a part of the surface thereof. It is widely used for various works such as carrying work. The lining of work gloves is roughly classified into two types: a sewing type and a knitted (knitted glove) type. Of these, the lining of the former sewing type necessarily has a seam, and the stitch hits a finger, which significantly reduces the wearing feeling of the glove. In recent years, work gloves using a seamless knitted lining have been increasing.

[0003] However, knitting type lining (hereinafter, referred to as
"Knitted gloves". ) Has a coarser mesh than the sewing type lining. For this reason, when a rubber film is formed on the respective surfaces of the sewing type lining and the knitted glove under the same conditions, the so-called strike-through in which the rubber seeps out on the inner surface of the sewing type lining hardly occurs. The phenomenon that strike-through occurs remarkably on the inner surface of the glove and rubber is clogged in the mesh of the knitted glove is observed.

[0004] If strike-through occurs remarkably, a sense of incongruity occurs when gloves are worn, and if the mesh is clogged with rubber, the knitted gloves are hardened. Then, in order to solve such a problem, measures to reduce the degree of knitting of the knitted gloves or to increase or increase the number of yarns can be considered. However, in this case, since the entire knitted glove becomes hard, a similar problem of a reduction in wearing feeling is caused.

[0005] It is an object of the present invention to provide a knitted glove which is free from excessive strike-through when a rubber or resin film is formed on the surface of the knitted glove, and which has a flexible knitted glove and is excellent in wearing feeling and workability. To provide gloves and a method of manufacturing the gloves.

[0006]

Means for Solving the Problems and Effects of the Invention A working glove according to the present invention for solving the above-mentioned problem has a knitted glove on which at least a part of a surface is formed of a film made of a soft material, The knitted glove is obtained by eluting the yarn containing the water-soluble synthetic fiber from a glove knitted with the yarn containing the water-soluble synthetic fiber. According to the present invention, the knitted gloves can be made flexible, and furthermore, an excessive strike-through at the time of forming a film made of a soft material on the surface of the knitted gloves can be prevented, so that the wearing feeling of the working gloves can be improved. And workability can be maintained.

The knitted glove in the working glove according to the present invention is knitted by a blended yarn of a water-soluble synthetic fiber and a water-insoluble fiber, or a yarn made of a water-soluble synthetic fiber and a water-insoluble fiber. It is preferable that these are knitted together. Further, it is more preferable that the knitted gloves contain 30 to 70% of a water-soluble synthetic fiber.
The method for manufacturing a working glove according to the present invention includes forming a knitted glove with a yarn containing a water-soluble synthetic fiber, forming a coating made of a soft material on at least a part of the surface of the knitted glove, and then forming the knitted glove. Characterized in that water-soluble synthetic fibers are eluted therefrom.

According to the method for manufacturing working gloves according to the present invention, by forming knitted gloves with a regular knitting machine using a knitting machine, it is possible to prevent excessive strike-through from occurring when a film made of a soft material is formed. It is possible to impart flexibility to the knitted glove itself by eluting the water-soluble synthetic fibers after the film is formed. Although the work glove thus obtained is lined with a seamless knit glove, the work glove is flexible and has excellent wearing feeling and workability without a decrease in the wearing feeling and working feeling due to the strike-through.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The working glove of the present invention and a method for manufacturing the same will now be described in detail. For example, as shown in FIG. 1, the work glove 10 of the present invention includes rubber on a part of the surface of the knitted glove 11 (in FIG. 1, the finger 13, the palm 14 and the back of the hand (not shown)). And a film 12 made of a soft material such as resin. Also, work gloves 1
The knitted glove 11 of No. 0 is obtained by eluting the yarn containing the water-soluble synthetic fiber from the glove knitted with the yarn containing the water-soluble synthetic fiber.

[Coating Made of Soft Material] In the work glove of the present invention, the coating 12 made of a soft material is provided on at least a part of the surface of the knitted glove. Here, knit glove 1
At least a part of the surface of the knitted glove 11
(Ii) The finger part 13 and the palm part 14 of the knitted glove, (i)
ii) The finger portion 13, the palm portion 14, the back of the hand, and the like of the knitted glove (see FIG. 1). Also, the sleeve 15 of the knitted glove 11
The entire surface including

Examples of the film made of the soft material include those formed by using a rubber latex or a resin emulsion. Examples of the rubber latex include various conventionally known rubber latexes such as natural rubber (NR) latex, acrylonitrile-butadiene rubber (NBR) latex, styrene-butadiene rubber (SBR) latex, and ethyl methacrylate graft (MG) latex. No. Above all, NR latex and MG latex are suitable for improving the strength of the film and the flexibility of the working gloves.

The natural rubber (NR) latex is a so-called deproteinized natural rubber (treated in addition to various known natural rubber latexes such as a field latex and an ammonia latex) which has been subjected to a treatment for removing proteins in the latex. DPNR) latex. The rubber latex is compounded with a vulcanizing agent, a vulcanization accelerator, a vulcanization accelerating aid, and the like, and, if necessary, other additives.

Examples of the vulcanizing agent include sulfur; organic sulfur-containing compounds such as trimethylthiourea and N, N'-diethylthiourea. These can be used alone or in combination of two or more. . The amount of the vulcanizing agent is determined depending on the degree of pre-vulcanization and the amount of the vulcanization accelerator and the like, and is usually 0.1% based on 100 parts by weight of the rubber solid content in the rubber latex. It is set in the range of 1 to 5 parts by weight, preferably 0.5 to 2 parts by weight. Examples of the vulcanization accelerator include zinc N-ethyl-N-phenyldithiocarbamate (PX), zinc dimethyldithiocarbamate (PZ), and zinc diethyldithiocarbamate (E
Z), zinc dibutyldithiocarbamate (BZ), 2-
Zinc salts of mercaptobenzothiazole (MZ), tetramethylthiuram disulfide (TT) and the like can be mentioned.
These can be used alone or in combination of two or more. The compounding amount of the vulcanization accelerator is preferably adjusted to about 0.5 to 3 parts by weight based on 100 parts by weight of the rubber solid content of the rubber latex. Examples of the vulcanization accelerator include zinc white. The amount of the vulcanization accelerator is 0.5 to 3 parts by weight per 100 parts by weight of the rubber solid content of the rubber latex.
It is preferable to adjust to about parts by weight.

On the other hand, examples of the resin emulsion include a vinyl chloride resin emulsion and a urethane resin emulsion. The resin emulsion preferably contains a cross-linking agent in order to make the cross-linking property of the resin sufficient and to improve the strength of the glove. When the resin emulsion has a self-crosslinking property, the film can be formed without blending a crosslinking agent, but the blending of the crosslinking agent can further improve the strength of the glove.

Examples of the crosslinking agent include various conventionally known crosslinking agents used for processing polymers, such as zinc white, melamine resin and epoxy resin. The amount of the crosslinking agent is not particularly limited, but is preferably 1 to 10 parts by weight, particularly 1 to 10 parts by weight, based on 100 parts by weight of the resin solid content of the resin emulsion.
It is preferably 5 parts by weight. [Knitted gloves] In the working gloves of the present invention, knitted gloves are first knitted with yarns containing water-soluble synthetic fibers. Examples of the yarn containing a water-soluble synthetic fiber include a blended yarn of a water-soluble synthetic fiber and a water-insoluble fiber, and a mixture of a yarn made of a water-soluble synthetic fiber and a yarn made of a water-insoluble fiber.

As a yarn made of a water-soluble synthetic fiber (hereinafter, referred to as "water-soluble yarn"), for example, a water-soluble vinylon yarn made of polyvinyl alcohol as a raw material can be used. Specifically, Kuraray Co., Ltd. brand name "Kuraron K-II" etc. is mentioned. The water-soluble synthetic fiber and the water-soluble yarn,
It is preferably one that dissolves in water at 10 to 100 ° C, preferably 50 to 100 ° C, more preferably 70 to 100 ° C. By setting the elution temperature of the water-soluble synthetic fiber in the above range, the water-soluble synthetic fiber and the water-soluble yarn do not dissolve in the rubber latex or the emulsion, and can be efficiently removed during post-processing. it can.

Examples of the water-insoluble fiber include various conventionally known fibers used for knitted gloves, such as cotton yarn, wool, acrylic fiber, polyester, and polyethylene. The gauge of the knitted gloves, the fineness of the water-soluble yarn or the yarn made of the water-insoluble fiber, and the like are not particularly limited, and may be appropriately set according to the use of the working glove. Generally, the thickness of the blended yarn, water-soluble yarn or water-insoluble fiber forming the knitted gloves is about 6 to 10 single yarns of 30th yarn, and 2 to 30 after elution of the water-soluble synthetic fiber. What is necessary is just to set about four.

When knitting a knitted glove with a yarn containing a water-soluble synthetic fiber, it is preferable that the stitches be packed as much as possible. If the degree of coarseness is rough at this stage, strike-through may occur significantly when a film made of a soft material is formed on the surface. Since the water-soluble synthetic fibers are dissolved and removed from the knitted gloves after the film is formed, even if the knitted gloves are knitted tightly, the flexibility of the knitted gloves in the final work gloves is sufficient. Is not impaired.

When knitting a knitted glove, the content of the water-soluble synthetic fiber in the yarn containing the water-soluble synthetic fiber is not particularly limited, but is usually 30 to 70% by weight, preferably 50 to 60% by weight. Set to% by weight. When the content of the water-soluble synthetic fiber is below the above range, there is a possibility that sufficient flexibility cannot be imparted to the knitted glove after the water-soluble synthetic fiber is eluted. Conversely, if the content of the water-soluble synthetic fiber exceeds the above range, the strength of the knitted glove after the water-soluble synthetic fiber is eluted may be insufficient.

[Manufacturing method of working gloves] The working gloves of the present invention include (1) preparation of knitted gloves, (2) formation of a film on the surface of knitted gloves, and (3) water solubility from knitted gloves. Manufactured by elution of yarn containing synthetic fibers. The knitted glove is formed from a yarn containing a water-soluble synthetic fiber as described above, and is preferably knitted by a blended yarn of the water-soluble synthetic fiber and the non-water-soluble fiber, or a water-soluble yarn. And a yarn composed of a water-insoluble fiber.

The coating made of a soft material is formed, for example, by the dipping method using the above-mentioned rubber latex or resin emulsion. That is, the coating is formed by placing a knitted glove on a glove mold and dipping the knitted glove in the rubber latex or resin emulsion together with the glove mold. After immersion, the film formed on the surface of the knitted glove may be dried and vulcanized (crosslinked) according to a conventional method. The film is formed by the above-mentioned immersion method,
(a) A so-called shower method in which rubber latex or resin emulsion is sprayed on knitted gloves. (b) A mold equipped with knitted gloves in thickened rubber latex or resin emulsion is dried while rotating to prevent dripping. (C) a so-called heat-sensitive method of immersing a rubber latex or resin emulsion imparted with heat-sensitivity,
(d) It can also be formed by an ordinary coagulation solution method or the like.
The formation of a film by these methods may be performed according to a conventional method.

After a film made of a soft material is formed on the surface of the knitted glove, the laminate of the knitted glove and the film is removed from the glove mold and immersed in water, or the reversely demolded laminate is removed. By spraying water or steam, the water-soluble synthetic fibers are dissolved and removed from the knitted gloves. Thus, the working glove of the present invention is obtained. The knitted gloves thus obtained are coarser with the elution of the water-soluble synthetic fibers,
It is highly flexible. In addition, a film made of a soft material is formed on at least a part of the surface, but the occurrence of strike-through is sufficiently suppressed,
Therefore, the mountability is good.
