Abstract:
A method of manufacturing textured yarn comprises providing a crimped yarn composed of numerous crimped and entangled together thermoplastic synthetic fibers, partially removing some of the crimp from the crimped yarn, heating and pressing together the resulting partially crimped yarn to contact the fibers at their mutually intercrossed locations with sufficient pressure and at a sufficient temperature to effect permanent transverse deformation of the fibers at their contact points, and terminating the heating and pressing to obtain a textured yarn composed of numerous fibers having longitudinally and randomly spaced transverse deformities. The yarn is initially crimped by false twisting and steam setting, and some of the crimp is removed from the crimped yarn to remove from 75 to 95 percent of the crimp.
Abstract:
AN IMPROVED SYNTHETIC TEXTURED YARN COMPOSED OF MORE THAN TWO KINDS OF THERMOPLASTIC SYNTHETIC FILAMENTS HAVING DIFFERENT FLEXURAL RIGIDITIES, TORSIONAL RIGIDITIES, FINENESS AND MIXING RATIOS. PARTICULAR DENFINITIONS IN THE RELATIONS AMONG THOSE FACTORS ASSURES REMARKABLY ENHANCED BULKINESS AND CRIMP RIGIDITY OF THE THE YARN COMPOSED OF THE FILA-
MENTS. DIFFERENCE IN THE CROSS SECTIONAL PROFILES OF THE COMPONENT FILAMENTS PROVIDES ADDITIONAL DEEP COLOUR EFFECTS TO THE TEXTILE FABRIC MADE OF THE TEXTURED YARN.
