Description

[Detailed description of the invention] This invention is used to prevent ignition accidents caused by the generation of static electricity in the production and storage of flammable liquids, or to prevent falls caused by electric shocks caused by static electricity during work at high places such as construction sites. The invention relates to anti-static gloves worn as anti-static gloves.

Conventionally, vinyl gloves have been used as the gloves, but if the object being handled is electrically charged, spark discharge occurs when these gloves come into contact with the object, and at the same time, the glove receives a strong electric shock. Furthermore, even if the human body itself is electrically charged, the same result will occur if the human body touches a grounded object, and this will not prevent accidents. For this reason,
Recently, conductive fibers have been developed in which acrylic fibers are impregnated with copper sulfide to give them electrical conductivity.This fiber has both anti-static properties due to corona discharge and conductivity, so it has been used in gloves. It is practiced to weave it and wear it while it is in contact with the ground. However, the conductive fibers are expensive and have the disadvantage of significantly increasing the unit price of the gloves.

In contrast, in the present invention, the conductive fibers (cotton-like fibers) are added to non-conductive fibers such as raw cotton by 1 to 10% by weight.
%, preferably about 3 to 8%, and thoroughly stirred, this mixed cotton fiber is used to make yarn and knitted into gloves, and as shown in the drawing, the overall structure is a mesh fiber structure. It's getting old. As a result, the conductive fibers are dispersed in the non-conductive fibers, and form an interconnected network that is very loose or just about to touch each other, so that static elimination using corona discharge of the conductive fibers is difficult. It was found that the effect was fully exhibited throughout the glove and was comparable to conventional gloves made of conductive fibers.

In the present invention, as mentioned above, the conductive fibers are dispersed in the non-conductive fibers and are interconnected with the non-conductive fibers in a loose network. Therefore, gloves with a high static elimination effect can be obtained by using a small amount of conductive fiber. For example, 100% conductive fiber yarn and 100% cotton yarn
In the case of a blended yarn made of tightly twisted yarns, the resistance value (resistance value between the hand insertion part of the glove and the tip of the middle finger)
In order to obtain gloves with a resistance of 2.5 x 10 ⁵ Ω or less, it is necessary to increase the blending rate of conductive fibers to 30% by weight or more, but in the case of the present invention, the objective can be achieved with a blending rate of about 3% by weight. Can be done.

The drawing shows the glove of the present invention, in which four fingers are knitted in a bag-like manner in parallel, similar to ordinary gloves, using yarn made of non-conductive raw cotton mixed with a small amount of conductive fiber. The bag-shaped upper part 1 of the palm flap is knitted with the knitting width, then the bag-shaped lower part 2 of the palm flap 2 is knitted with the knitting width that includes the thumb, and then the wrist part 3 connected to this is knitted.
Elastic rubber threads are inserted into every other course and intertwined with knitting yarn, and the four courses at the mouth end are constructed by inserting elastic rubber threads into each course and knitting and intertwining them with rubber thread.

In addition, since the purpose of the glove of the present invention is to eliminate static electricity, the glove does not necessarily have a perfect shape; for example, the glove may have a shape in which the fingertips are cut off.

As a result of testing the above gloves, the resistance value was
It was 2.5×10 ⁵ Ω or less, so it could be considered a conductor in terms of static electricity, and in terms of current conductivity, instantaneous conduction occurred and instantaneous static electricity was removed. Furthermore, even when the device was actually worn and came into contact with a high-voltage generator, there was no spark discharge or electric shock, and static electricity was removed quickly.

As explained above, the present invention is capable of reducing the electric charge by the corona discharge of the conductive fibers contained therein, and since the whole is made of almost non-conductive cotton yarn, the conductive fibers can be reduced. The conductive fibers are surrounded by non-conductive cotton threads, so there is no risk of breakage, so they are strong and easy to wash, and can be produced at less than 1/10th the cost of conventional conductive fiber gloves. There are many advantages.

In addition to cotton, non-conductive cotton fibers include various other cotton fibers, such as nylon fibers, acrylic fibers, tetron fibers, acetate fibers, vinylon fibers, and cotton fibers. There are fibers, linen fibers, etc.
