Polyamide fibers composed of the polyamide and methods for producing thereof
Abstract
Abstract A POLYAMIDE CONSISTING OF A SUBSTANTIAL HOMOPOLYMER OF POLY-BIS(PROPOXY)ALKYLENE TEREPHTHALAMIDE HAVING THE RECURRING STRUCTURAL UNIT SHOWN BY THE FORMULA I -(NH-(CH2)3-O-(CH2)N-O-(CH3)3-NH-CO-1,4-PHENYLENE-CO)WHEREIN N IS A POSITIVE INTEGER OF 2 TO 4, HAS AN IMPROVED MODULUS AND ANISTATIC PROPERTY. THIS POLYMIDE CAN BE OBTAINED BY POLYMERIZING THE CORRESPONDING ETHERDIAMINE WITH TEREPHTHALIC ACID. A FIBER CONSISTING OF THE POLYAMIDE HAS AN EXCELLENT ANTISTATIC PROPERTY, SPINNABILITY HEAT STABILITY, MODULUS, STRENGTH, ELONGATED AND DYE RECEPTIVITY. THE MODULUS OF THIS FIBER CAN BE FURTHER IMPROVED BY DRAWING THE UNDRAWN FILAMENT AND SUUCCESSIVELY SUBJECTING THE DRAWN FILAMENT TO A HEAT TREATMENT UNDER TENSION.
