Problems solved by technology

This type of conductive fiber has attracted more and more attention. However, due to the conjugated structure of the conductive polymer main chain, it is difficult to process the fiber and has poor thermal stability. In addition, the polymerization monomer is toxic and the synthesis process is complicated. At present, still not widely used

Abstract

The invention provides sol type conductive polyester fiber. The polyester fiber comprises a polyester fiber body, a sol layer attached to the outer side of the fiber body, and a conductive layer on the outer side of the sol layer and in internal pores. According to the sol type conductive polyester fiber, the surface polarity of the polyester fiber is overcome; a polyester fabric is finished by adopting sericin; the antistatic property / conductivity of the polyester fabric is improved by doping of Fe<3+>; the sericin is doped with Fe<3+> and is finished on the fabric, Fe<3+> enters a sericin network, and then polypyrrole is grafted into a sericin network film, so that the number of conductive particles is increased, and the conductivity is improved; and a conductive material is permanently grafted in a manner of adhering a gel layer, and the mechanical property of the fiber is maintained.

Description

technical field [0001] The invention relates to functional fibers, in particular to a sol-type polyester fiber and a preparation method thereof. Background technique [0002] Functional fibers are endowed with various additional functions to ordinary fibers through spinning and post-processing methods, such as antibacterial, anti-ultraviolet, antistatic, anti-electromagnetic radiation, flame retardant, moisture absorption and other functions. Nowadays, the antistatic requirements for clothing and textiles in special workplaces and daily life are getting higher and higher. As one of the important materials to eliminate static electricity, reduce static electricity hazards, and realize static electricity protection, conductive fibers have become the world's research on functional fiber materials. hotspot. Human beings have started to develop conductive fibers since the 1960s. [0003] Conductive fibers are functional fibers that eliminate static electricity through electron ...
