With the continuous improvement of anti-static requirements in industries such as electronics, semiconductors, and LCDs, the requirements for conductive fibers used in work clothes are becoming higher and higher. Conductive fibers are not yet clearly defined. Usually the resistivity is less than 107Ω. The fiber of cm is defined as a conductive fiber. Conductive fibers used in antistatic clothing should have appropriate fineness, length, strength and flexibility. They can be well blended with other common fibers, easily blended or interwoven, and have good resistance to friction, buckling, oxidation and corrosion. The ability to withstand the physical and mechanical effects of textile processing and use; does not affect the feel and appearance of the fabric; excellent electrical conductivity and durability.
The current varieties of conductive fibers are: metal fibers (stainless steel fibers, copper fibers, aluminum fibers, etc.), carbon fibers, and organic conductive fibers. The organic conductive fiber includes metal plating of ordinary textile fiber; carbon plating of common textile fiber; conductive fiber made of conductive material such as carbon black, graphite, metal or metal oxide mixed with ordinary high polymer or composite spinning; An organic conductive fiber made by directly spinning a molecule. These conductive fibers can be classified into three types: a conductive component uniform type, a conductive component coated type, and a conductive component composite type.
Metal fibers have good electrical conductivity, heat resistance and chemical resistance. However, for textiles, the metal fiber has small cohesion, poor spinning performance, limited color of finished products, and is mostly used for carpets and overalls fabrics. It is expensive when made of high-fineness fibers; carbon fiber has good electrical conductivity, heat resistance and chemical resistance. , but high modulus, lack of toughness, intolerance of bending, no heat shrinking ability, not suitable for textile use; organic conductive fiber made of polyacetylene, polyaniline, polypyrrole, polythiophene and other polymer conductive materials directly spinning The organic conductive fiber is difficult to spin, and the price is higher, and it is also difficult to use in the antistatic clothing fabric. From the current application experience, coated and composite organic conductive fibers are most suitable for the manufacture of permanent antistatic textiles.
