JP7191008B2 - Antistatic clothing - Google Patents

Description

TECHNICAL FIELD The present invention relates to antistatic clothing containing conductive yarn in specific portions.

In recent years, due to the maintenance of air conditioning equipment, the indoor temperature is kept comfortable throughout the year. On the other hand, indoor humidity is often low in both summer and winter.
For this reason, heat-retaining clothing used in winter tends to accumulate static electricity in the clothing due to the activity of the wearer, which leads to discomfort due to static electricity discharge when the wearer is undressing.

As a method for reducing the discomfort caused by static electricity discharge, there are known antistatic post-treatments that make it difficult for static electricity to accumulate in clothing products, and methods in which conductive fibers or metal fibers are incorporated into the entire clothing product.
However, the function of antistatic post-treatment to clothing products deteriorates with repeated washing.
In the method of including conductive fibers or metal fibers in the entire clothing product, carbon black or the like is used as the conductive fibers, resulting in a gray or black color. It has a metallic luster. For this reason, when the color of the clothing product is light, the influence of the color of the conductive fiber and the metal fiber appears on the clothing product, which is not preferable.
Patent Literature 1 describes that by setting the number of meshes formed by conductive yarns to 70% or less of the total number of meshes, conductivity is generated in the planar direction of the conductive stretchable knitted fabric. However, since the conductive yarn is used throughout the garment, the color of the conductive fiber stands out if the color is light. For this reason, only dark colors can be used for clothing, and the clothing lacks attractiveness.
Patent Document 2 discloses a knitted fabric that is entirely or partially covered with a composite yarn covered with a synthetic fiber that has been rendered conductive by any one of plating, metal deposition, sputtering, and conductive paint. is described. However, since the color of the conductive fiber greatly affects clothing products, it is difficult to use it for general winter clothing such as sweaters.
Therefore, a method has been proposed to reduce the influence of the color of conductive fibers on clothing products by using conductive threads as sewing threads (Patent Document 3).

However, in the invention of Patent Document 3, since there is no conductive fiber in the body, the color of the conductive fiber does not affect the color of the conductive fiber. It has degraded product quality.

The object of the present invention is to use colored conductive fibers as part of the design in specific parts, so that most parts of the body can be used in light colors, and have antistatic performance and washing durability. to provide clothing that has
