SHAPE MEMORY TYPE POLYAMIDE AND PROCESS FOR PRODUCING POLYAMIDE FABRICS HAVING SHAPE MEMORY PROPERTY

摘要

Shape memory type polyamides are provided to produce polyamide fabrics which show a shape memory property and to ensure excellent restoring force. Shape memory type polyamides are prepared by adding polyfunctional carboxylic acid and polyfunctional amine during the polyamide polymerization using epsilon-caprolactam or hexamethylenediamine and adipic acid as main materials, wherein the total content of aromatic components introduced by the polyfunctional carboxylic acid and/or polyfunctional amine ranges from 0.4 mol% to 10 mol%, based on the main materials of the polyamide.
