Experimental Manufacture of Antistatic Synthetic Fibers

In this paper, the details and preliminary results of the investigations were presented for the use of copolymers of polyamides containing disulfide linkages, sulfhydryl groups and sulfonic acid groups as antistatic agents for nylon 66 filaments. Copoly hexamethylene (3,3'-dithiodipropio-adipo) amide (copoly-HDA) was synthesized from 3,3'-dithiodipropionyl chloride, adipoyl chloride and hexamethylene diamine by an interficial polycondensation method. Conditions for synthesis of the copoly-HDA were discussed. The copoly-HDA and nylon 66 chips were mined in several component ratios and then spun by wet spinning method. The resulting filaments were treated with reducing and oxidizing agents in order to make hygroscopic filaments, Electro-specific resistance of those and nylon 66 filaments were measured in order to discuss their antistaticity. Antistatic effects of copoly-HDA were recognized on those filaments at room temperature, which could be explained by assuming that the disulfide arrangements were made pseudo-conjugated double bond.
