Background
The textile material is an electrical insulator material, has high specific resistance generally, and is especially synthetic fibers with low moisture absorption performance such as terylene, acrylic fiber, polyvinyl chloride fiber and the like. Thus, during the textile process, there is intimate contact and friction between the fibers and the machine parts. Resulting in the transfer of charge to the surface of the object and the consequent generation of static electricity. The fibers with the same charge repel each other, and the fibers with different charges attract the machine parts, so that the sliver is hairy, the yarn hairiness is increased, the package forming is poor, the fibers are stuck on the machine parts, the yarn broken ends are increased, and a dispersive strip shadow is formed on the cloth surface. After the clothes are electrified, a large amount of dust is adsorbed, the clothes are easy to stain, and the clothes and the human body, the clothes and the clothes can also generate the phenomenon of winding or generate electric sparks. Therefore, the electrostatic interference affects smooth processing, the quality of the product, the wearability of the fabric, and the like. When the static electricity phenomenon is serious, the static voltage is up to thousands of volts, sparks are generated due to discharge, and fire disasters are caused, so that serious consequences are caused.
Therefore, the effective removal of static electricity in textile fabrics is a technical problem to be solved at present.
