Traditional vs. New Antistatic Technology

Today, electrostatic products have endangered all walks of life. The textile industry has also suffered from static electricity. Anti-static technology has also infiltrated the textile industry. This is an indispensable topic for the textile industry. We will introduce the contrast between the traditional anti-static technology and the new anti-static technology.

Traditional antistatic technology

Traditional methods for antistatic processing of textiles include:

1) Use antistatic fiber. Antistatic fiber has high hygroscopicity and equilibrium moisture regain, can absorb water molecules in the air, so that textiles have good antistatic properties, that is, it is not easy to generate static electricity, it is easier for the static electricity that has been generated to escape.
2) Apply antistatic agent. With the popularization and application of high-speed spinning and deformation processing equipment, it is easy for the yarn surface to accumulate friction to generate electrostatic charges, so antistatic agents must be added to the spinning oil agent. The antistatic mechanism is the same as antistatic fiber.
3) Stainless steel fiber blended. Using the good conductive properties of metal fibers, the static charges that have been generated are easily dissipated.
4) Organic conductive filaments inlaid or organic conductive staple fiber blends. The antistatic mechanism is similar to that of stainless steel and other metal conductive fibers, that is, it has the effect of easily causing the dissipation of charges. For organic conductive fibers, there are not only gray products using carbon black as a conductive material, but also white or nearly white organic conductive fibers with metal oxides and metal carbides as conductive materials.

New antistatic technology

In recent years, two types of conductive fibers have appeared and been promoted, which can be applied to the antistatic processing of textiles.
1) Silver-plated fibers or filaments. Since silver fibers have good antibacterial and conductive properties, textiles containing less silver plated fibers (about 1%) have antibacterial functions and good antistatic properties, which can be formed in fabrics when silver-plated fibers are used. Conductive network structure and this structure is relatively dense, it can also have a good electromagnetic shielding effect. For the antistatic function, due to the good conductivity of the silver fiber, the dissipation ability of the static charge is stronger than that of the organic conductive fiber, so in general, the antistatic effect is better than the organic conductive fiber.
2) Conductive polymer materials. Such as polyaniline, polypyrrole, polythiophene and so on. These conductive polymers have only begun to enter engineering applications in recent years. Nowadays conductive polymers can be made into fibers or paints, which have lower resistivity and can be used as a new type of raw material for antistatic processing of textiles.
