How to distinguish the grade of anti-static fabrics
The progress of anti-static fabrics has given rise to various specifications and types of anti-static fabrics. We can roughly divide these antistatic fabrics into three major categories.
1. An anti-static fabric is a kind of anti-static fabric mixed with conductive fibers in general fabrics. This kind of anti-static fabric is now generally accepted and recognized because it is not affected by the environment where it is located. The antistatic properties of this antistatic fabric and the type of conductive fiber and the distribution of conductive metal, graphite, carbon black, etc. in the fiber can be divided into uniform conductive component type, conductive component covering type, conductive component bonded type and conductive component type. There are four types of ingredient mixes. Other laminated conductive fibers containing conductive components such as carbon black and graphite can be directly used for weaving filaments. By embedding a conductive filament at certain intervals (such as about 1.5 cm) in the warp yarns, a good result can be obtained. Anti-static effect, it is currently the best conductive fiber used to weave anti-static clothing.
2. The second type of antistatic fabric is to add antistatic agents, such as phosphate esters, sulfonates and other surfactants, or introduce third monomers into the polyester fiber or nylon polymer fiber. Get durable antistatic fibers. Since most antistatic agents in additives are surfactants that react or decompose when exposed to alkali, alkaline cleaning agents should be avoided when finishing or cleaning fabrics to prevent them from affecting the antistatic effect. This fiber is suitable for dust-free fabrics. Clothing, sterile clothing, and can also be used for civilian work clothes.
3. The third type of antistatic fabric is to use antistatic agent to perform resin finishing on the fibers of the fabric. After padding and baking, it adheres to the surface of the fiber fabric, so that the fabric has a certain Antistatic effect. At present, it is only used for general work clothes to remove common static electricity phenomena such as clothing adsorption on the body, spark discharge, and ash absorption.
Different classifications of anti-static fabrics are suitable for different working environments. They are mainly based on the protection standards for static electricity. Therefore, it is not necessarily a good choice of anti-static fabrics. It is better to choose the appropriate anti-static fabrics. of.
