Problems solved by technology

[0006] The volume resistivity of polymer polyester fiber at room temperature is as high as 10 13 Ω.cm, usually considered as an insulator fiber, for many years scientific and technological workers have used ordinary fiber-forming polymers as a matrix to develop conductive fibers of polymer materials by adding conductive substances, so that the fibers have conductive properties and at the same time Combined with the excellent processing performance of ordinary synthetic fibers, it becomes a functional fiber with spinnability; but the conductivity and fiber strength of polymer matrix conductive fibers are not as good as metal conductive fibers, and metal conductive fibers are too hard and lack elasticity. very limited in use

Abstract

The invention discloses a method for manufacturing conductive polyester fibers. The method comprises the following steps of: adding conductive materials including ATO conductive powder, superconducting carbon black, zinc oxide whiskers, potassium titanate whiskers and the like into polyester to prepare conductive polyester; and taking the conductive polyester as a skin layer to prepare polyester conductive fibers with other polyesters through a composite spinning technology. Through the method, the skin layer part of the fibers contains conductive substances, so that the fibers have excellent physical and processing performance of synthetic fibers while having conductivity, the resistivity of the polyester fibers can be greatly reduced, and the breaking strength of the fibers can also be improved.

Description

technical field [0001] The invention relates to a method for manufacturing conductive polyester fiber, including ATO conductive powder, superconducting carbon black, zinc oxide whisker (ZnO), conductive potassium titanate whisker (PTW) and other fiber manufacturing methods, belonging to functional polyester Fiber Manufacturing Technology. Background technique [0002] Polyester fiber is made of polyethylene terephthalate, and the trade name in China is polyester, which is currently the largest variety of synthetic fiber. Polyester fiber is an ideal textile raw material. Because of the high rigidity of the fiber macromolecular chain and high elastic modulus, the fiber is not easily deformed. It is easy to wash and dry; it also has good heat resistance, sun resistance and abrasion resistance, and can be used at -70-170 °C; in industry, high-strength polyester can be used as tire cords, conveyor belts, fire hoses, cables, Fishing nets, etc., can also be used as electrical ins...
