Description

Antistatic fabric

Technical Field

The utility model relates to a surface fabric, especially an antistatic surface fabric.

Background

Static electricity on human body is mainly caused by friction between clothes or between clothes and human body, because of different atomic structures of different materials, "charge amount" is different when wearing clothes made of different materials, for example, wearing clothes made of chemical fiber is easy to generate static electricity, while cotton clothes generate less static electricity. Static electricity poses certain danger to human body, so that it is required to eliminate static electricity carried by human body.

At present, the basic principle and method of fabric antistatic: 1) an antistatic finish is used; 2) a chemical modification method; 3) blended or embedded metal fibers. The action mechanisms of the former two methods are both to improve the moisture regain of the fabric and reduce the insulativity, thereby accelerating the electrostatic leakage. However, in a dry environment or after many times of washing, the antistatic effect is reduced or insignificant, and the antistatic ability is not durable. The third method belongs to an antistatic method with physical properties, but the elasticity of the yarn can be influenced after the metal fiber is blended or embedded, so that the elasticity of the fabric is influenced, and the hand feeling of the fabric is stiff.
