Abstract

The invention relates to a method for manufacturing light-color conductive polyester fibers. The method comprises the following steps of: adding conductive materials including ECP-20 conductive titanium pigment, ATO conductive powder, zinc oxide whiskers, potassium titanate whiskers and the like to prepare light-color conductive polyester; and preparing the light-color conductive polyester and other polyesters such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT) and the like into the light-color conductive polyester fibers in a mass ratio of (25-35): (75-65). The light-color conductive polyester fibers have good conductivity and durability, and particularly when the humidity is low, the light-color conductive polyester still has good and durable self-generating conductivity, so that the light-color conductive polyester fibers have great use in the fields of industry, civilian use and the like.

Description

technical field [0001] The invention relates to a method for manufacturing light-colored polyester conductive fibers, including the manufacture of conductive fibers such as ECP-20 conductive titanium dioxide, ATO conductive powder, zinc oxide whisker (ZnO), and conductive potassium titanate whisker (PTW). The method belongs to the 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, and has good heat resistance, light resistance and abrasion resistance, and can be used at -70 ~ 170 °C. Industrially, high-strength polyester can be used as tire cords, conveyor belts, fire hoses, cables, fishing ...
