Abstract

PROBLEM TO BE SOLVED: To obtain the subject gloves having good feeling to user and strengths by partially treating gloves made of fabric with an agent for promoting impregnation into a resin component, impregnating the gloves into the resin component and thickly applying the resin layer to only necessary parts. SOLUTION: An agent for promoting impregnation into a resin component is attached to necessary parts of gloves made of fabric by a method such as coating, spray, printing, etc., and gloves are immersed into the resin component such as NBR latex or vinyl chloride sol and dried. As the impregnation promoter, water (and an anionic surfactant, a nonionic surfactant, etc.) is used for the NBR latex and an organic solvent such as dioctyl phthallate is used for the vinyl chloride sol.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support-type glove and a method for producing the same, and more specifically, a support-type glove in which a large amount of a resin component is carried in a necessary portion to achieve both a feeling of use and strength, and a method thereof. Regarding manufacturing method.

[0002]

2. Description of the Related Art There are support type and non-support type gloves for household or work made of various kinds of rubber or vinyl chloride. Of these, support-type gloves are made of cloth knitted with a knitted fabric or the like, the surface of which is treated with rubber or a polymer substance.Because they are stronger than non-support-type gloves, they are widely used especially for work. ing.

Conventionally, as a support type glove, a cloth glove such as a seamless knitted fabric coated with vinyl chloride has been generally used and has been on the market, but recently, in addition to being excellent in oil resistance, it is excellent in piercing strength, And because it is lightweight, N
Support gloves using BR are also being provided as work gloves.

[0004]

However, the conventional support type gloves have their respective drawbacks, and none of them are sufficiently satisfactory. That is, in the case of an NBR support type glove, the NBR easily penetrates into the fibers of the cloth glove substrate with a normal NBR, and in some cases the back surface (inner side)
In some cases, an NBR layer may be formed, which is disadvantageous in that the flexibility is lower than in the case where vinyl chloride is used, the fingertip feel is poor, and there is a feeling of strangeness. In order to solve this drawback, there is a method of using NBR having poor permeability, but according to this method, the NBR and the cloth glove base material are separated from each other at the cuffs of gloves because of poor permeability of NBR into fibers. There was a drawback.

Also, in a support type glove using vinyl chloride, the thickness of the vinyl chloride layer with respect to the glove substrate is almost constant, so that there are cases where the required strength cannot be obtained. Therefore, there has been a demand for the development of a support-type glove in which the resin component is thickly attached only to a necessary portion and a simple manufacturing method thereof.

[0006]

Means for Solving the Problems As a result of intensive studies in view of the above problems, the present inventors have applied or dipped a resin component permeation enhancer to a portion of a cloth glove substrate to which the resin component is to be thickened, The present invention has been completed by finding that the permeation into the fiber layer increases the affinity with the resin component only in the fiber portion and the resin layer becomes thicker.

That is, the present invention provides a support type glove manufactured by partially treating a cloth glove substrate with a resin component permeation enhancer and then immersing it in a resin component, and a method for manufacturing the same.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION In order to carry out the present invention, first, it is necessary to partially coat or immerse a resin component permeation accelerator (hereinafter referred to as "accelerator") on a cloth glove substrate. .

As the glove base body to which the method of the present invention can be advantageously used, a sewn type glove using cotton or the like can be used, but a seamless type knitted glove can be sewn inside the glove. This is preferable because it eliminates the cost and improves the feeling of use, and the 20th to 50th knitting is particularly preferable.

On the other hand, the accelerator needs to be selected according to the type of resin component used on the surface of the glove. When the resin component is NBR latex or the like, water or a hydrophilic component and the resin component are vinyl chloride sol or the like. If so, it is necessary to use a lipophilic component. Examples of the hydrophilic component here include, for example, a solution in which an anionic surfactant such as alkylbenzene sulfonic acid or the like, a nonionic surfactant such as polyoxyethylene alkyl ether or the like is added to water,
As the lipophilic component, dioctyl phthalate (DO
P) and organic solvents such as diisononyl phthalate (DINP).

The above-mentioned treatment with the accelerator may be carried out only on the portion of the cloth glove base where the resin component is to be thickly applied. For example, in the NBR support type glove, the cuffs where peeling easily occurs may be mainly carried out. For vinyl chloride support-type gloves, for example, the fingertips, which are easily broken, may be mainly treated.

Examples of the method of treating the accelerator include coating, spraying and printing using a mold, and the accelerator can be adjusted to an appropriate viscosity and concentration as necessary.

In the support type glove of the present invention, the cloth glove substrate treated as described above after being attached to the mold or before being attached is dipped in a resin component liquid according to a conventional method, treated and dried. Is prepared by.

Of the resin components used for treating the fabric glove substrate, the NBR latex liquid has a surface tension of about 35 dyne / cm or more, especially 40 as compared with the ordinary latex liquid.
It is preferable to use those having a dyne / cm or more. The reason for this is that when a normal surface tension of 35 dyne / cm or less is used, the NBR latex liquid penetrates quickly into the fiber layer of the glove substrate, and the NBR glove is softened as a whole and solidified. This is because it can be lost.

In order to control the surface tension of the NBR latex liquid to the above range, it is necessary to adjust the kind and amount of the surfactant added to the latex liquid, and the surfactant for this purpose is particularly limited. However, for example, a fatty acid type surfactant or the like can be used.

For example, when potassium oleate is used as the surfactant, it may be added to the latex so that the soap cover ratio becomes about 70 to 90%. Alternatively, a commercially available high surface tension latex liquid, for example, Nipol 1562 (manufactured by Nippon Zeon Co., Ltd.) or the like may be used.

As described above, the cloth glove base material treated with the resin component is dried with hot air at about 60 to 120 ° C. for about 10 to 60 minutes after removing excess latex liquid as necessary, and then used as a support type glove. To be done.

In order to impart antibacterial and deodorant properties to the support type glove of the present invention, an antibacterial agent and a deodorant can be added to the resin component liquid. Examples of antibacterial agents that can be added include neocintol (manufactured by Shinto Paint Co., Ltd.),
Preventol BCM (manufactured by Bayer Co., Ltd.) and the like can be cited, and examples of the deodorant include Mizukanite (manufactured by Mizusawa Chemical Co., Ltd.) and the like.

Further, the support type glove of the present invention can be formed with a non-slip layer by treating it with a binder liquid containing an inorganic powder or an organic solid. This can also be performed by a conventionally known method.

[0020]

The present invention utilizes the difference in the penetrability of the cloth glove base material with respect to the resin component, which is caused by the partial treatment with the accelerator having a high affinity with the resin component. That is, the resin layer can be thickened only in a necessary portion of the above.
