Abstract:
PCT No. PCT/CH91/00177 Sec. 371 Date Apr. 7, 1992 Sec. 102(e) Date Apr. 7, 1992 PCT Filed Aug. 21, 1991 PCT Pub. No. WO92/03603 PCT Pub. Date Mar. 5, 1992.The process for making a polyamide filament having thermal and mechanical properties close to those of nylon 66 but without spherulites includes concentrating an aqueous solution of adipic acid-hexamethylenediamine salt containing from 1 to 10% by weight of epsilon -caprolactam and from 1 to 15% by weight of PA 6.HHT to form a condensed mixture; polycondensing the condensed mixture to form a polycondensed mass; and melt-spinning the polycondensed mass to form the polyamide filament. The process parameters are controlled to produce a polyamide filament consisting essentially of at least 80% by weight nylon 66 monomer, 1 to 10% by weight nylon 6 monomer and 1 to 15% by weight PA 6.HHT.
