Abstract

The invention relates to a method for manufacturing polyvinyl acetal conductive fibers. The method comprises the following steps of: adding conducting materials including ATO conductive powder, superconducting carbon black, zinc oxide whiskers, potassium titanate whiskers and the like into a fiber-grade polyvinyl alcohol spinning solution, and mixing, filtering and defoaming to prepare a conductive polyvinyl alcohol spinning solution; and ensuring that one part of the fibers becomes composite polyvinyl acetal conductive fibers containing conductive substances through a composite spinning technology. The polyvinyl acetal conductive fibers have low resistivity, high strength, durability and conductivity even the humidity is low.

Description

technical field [0001] The invention relates to a manufacturing method of polyvinyl acetal conductive fiber, which comprises fiber-grade polyvinyl alcohol (PVA), ATO conductive powder, superconductive carbon black, zinc oxide whisker (ZnO), conductive potassium titanate whisker The manufacturing method of conductive fibers such as (PTW) belongs to chemical fiber manufacturing technology. Background technique [0002] Polyvinyl formal fiber is obtained by spinning the fiber made of polyvinyl alcohol as raw material and treated with formaldehyde. It is called vinylon in China and vinylon in the world. The nature of vinylon is quite similar to that of cotton. It is called synthetic cotton, and its strength and wear resistance are better than cotton; vinylon filament is like silk, with good hygroscopicity. It is among the best in China; the specific gravity (1.26~1.30) is smaller than that of cotton, the thermal conductivity is lower, and the warmth retention is better; corrosi...
