PROCESS FOR MANUFACTURE OF TEXTURED ELASTIC POLYAMIDE THREAD CHARACTERIZED BY LOW LINEAR DENSITY Russian patent published in 1994 - IPC

Abstract RU 2021396 C1

FIELD: textile industry. SUBSTANCE: this process includes such steps as stretching, texturing with false twist thermal fixation and knotless package winding. Texturing step prescribes using thread composed of five elementary threads by allowing it to pass through friction discs at speed of 1420 to 1460 m/min and carrying out thermal fixation at temperature of 135 to 140 C. Stretching coefficient is in range of 2.96 to 3.02. EFFECT: higher quality. 1 tbl
