Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing work gloves having a flexible coating made of a vinyl chloride resin layer on the outer surface of a fabric such as a knitted or woven fabric.

Conventional work gloves with a vinyl chloride resin layer are made by knitting or sewing fiber threads or knitted or woven fabrics, and then a vinyl chloride resin layer is applied and formed on the gloves. be able to.

Conventionally, the main method for manufacturing work gloves has been the dipping method, with some using the coating method.

In the dipping method, a fabric such as a knitted fabric or a woven fabric is immersed in a vinyl chloride resin paste, so if the intervals between the fiber threads 10 that make up the fabric are wide, as shown in Figure 1A, the vinyl chloride resin paste will soak into the liquid. Due to the pressure, it penetrates into the gap between adjacent fiber threads 10, and at the same time, it becomes entangled with fiber thread 1 and becomes integrated.

Therefore, the vinyl chloride resin layer 2 becomes thick, and the work gloves themselves become stiff and stiff with no elasticity.

Therefore, when using this immersion method, as shown in Figure 1,
It is common to use knitted cloth with densely spaced fiber threads 1, but in this case, the oil-based plasticizer that makes up the vinyl chloride paste penetrates into the fiber threads 1 of the knitted cloth, which causes the vinyl chloride resin paste to In order to guide the fiber threads 10 into the gaps between adjacent fiber threads 10, the vinyl chloride resin paste and the fiber threads 1 are entangled and integrated, and the vinyl chloride resin layer 2 becomes thick, making the work gloves hard and non-stretchable.

On the other hand, when using the coating method, since there is no hydraulic pressure for the vinyl chloride resin paste, the vinyl chloride resin paste can be applied even if the spacing between the fiber threads 1 is widened as shown in FIG. 1A.

However, in this case as well, as described above, the vinyl chloride resin paste is guided by the penetration of the plasticizer that is its component and enters the gap between the adjacent fiber threads 10, intertwines with them and becomes integrated.

As a result, the vinyl chloride resin layer 2 becomes thick, hard enough to be used as a work glove, and lacks elasticity.

In order to prevent this, it is necessary to use a vinyl chloride resin paste with a high viscosity of about 9,000 to 15,000 centipoise, but in this case, the vinyl chloride resin paste will penetrate into the gaps between the fiber threads 1. Since the degree is only slightly relaxed, the thickness of the vinyl chloride resin layer 2 does not decrease when viewed from the left, and the problem is not solved.

In addition, knitted or woven fabrics are packed with polyacrylic resin emulsion or polyvinyl chloride powder in advance, and then polychloride with a relatively high viscosity, for example, about s, ooo centipoise, is applied. A method of applying a vinyl resin paste or a method of dipping the knitted or woven fabric in the polyvinyl chloride resin paste is also known, but these methods also do not leave a polyvinyl chloride resin layer on the plugging layer. Due to the weighting, the above-mentioned drawbacks still cannot be solved.

As described above, work gloves obtained by conventional manufacturing methods have a thick vinyl chloride resin layer formed by intertwining the vinyl chloride resin paste and the fiber threads of fabrics such as knitted and woven fabrics, so they are suitable for working, for example. When used as personal gloves, they are hard and have no elasticity, and the tactile sensation when touching objects is dull, resulting in poor workability and increased hand fatigue.

The present invention was made in order to eliminate the drawbacks of conventional work gloves, and its purpose is to use vinyl chloride resin that is thin, has good elasticity and flexibility, and has a good tactile feel. The present invention provides a method for manufacturing a work glove having a flexible coating consisting of layers.

Hereinafter, this invention will be explained based on FIGS. 2 to 4.

First, to explain the structure, the method for manufacturing work gloves according to the present invention consists of the following two steps.

That is, (1) The outer surface of the knitted fabric glove 3 or the woven fabric glove 4 in which the distance between adjacent fiber threads 5 is 1.5 times or more and 4.0 times or less than the thickness of the fiber thread 5 is repellent. A first step of forming an oil-repellent layer 6 by applying an oil-repellent treatment with an oil-based oil repellent, such as a fluororesin or a silicone resin; The vinyl chloride resin paste is applied to cloth gloves 4 without pressure by dripping or spraying so as not to apply the liquid pressure, and then heated and melted to completely gel and cooled. A second layer forming a crosslinked layer 7 of vinyl resin.
It consists of a process.

Here, the oil repellent treatment is performed by spraying an oil repellent onto the gloves 3 and 4 or by immersing the gloves 3 and 4 in an oil repellent.

The oil repellent treatment is performed after the gloves 3 and 4 are put on the flat shape, but it may be done before the gloves are put on.

The oil repellency of the oil repellent layer 6 prevents the polyvinyl chloride resin paste, which has an oil-based plasticizer composition, from entering the gaps between the fiber threads 5. The crosslinked layer 7 of vinyl chloride resin is literally crosslinked to the fiber threads 5 of the gloves 3 and 4 to form a thin layer.

If the distance between the twisted fiber threads 50 exceeds 4.0 times the thickness, the weight of the polyvinyl chloride resin paste will become excessive, and the polyvinyl chloride resin layer 7 will become thicker. The limit is twice as much.

As explained above, according to the present invention, the crosslinked layer 7 of polyvinyl chloride resin is formed thinly, so it is stretchable and soft.

Therefore, the workability is improved when it is fitted and used.

In particular, since the crosslinked layer 7 is thin, the tactile sensation when touching an object is not as dull as in conventional products, so it is suitable for work using the hands.

In addition, since the crosslinked layer 7 of polyvinyl chloride resin is formed thinly, the amount of polyvinyl chloride resin consumed as a raw material can be reduced, and since the gloves 3 and 4 can have a wide spacing between the fiber threads 50, consumption can be reduced, and resource conservation can also be achieved.
