Polyolefin-polyamide composite filaments having an improved adhering property and a method thereof
Abstract
Abstract COMPOSITE FILAMENTS OF A POLYOLEFIN AND A POLYAMIDE WHICH ARE HIGHLY CRIMPABLE WITHOUT SEPARATION OR CLEAVAGE ARE PRODUCED BY THE CONJUGATE SPINNING OF (1) A MOLTEN FIBER-FORMING POLYAMIDE SELECTED FROM THE GROUP CONSISTING OF NYLON-11 NYLON-12, NYLON-11.10, NYLON-11.11 AND NYLON-11.12 AND (2) A MOLTEN FIBER-FORMING POLYOLEFIN SELECTED FROM THE GROUP CONSISTING OF POLYETHYLENE AND POLYPROPYLENE. THE CONJUGATE SPINNING RATIO OF THE TWO POLYMERIC MATERIALS WHICH ARE EMPLOYED TO FORM THE COMPOSITE FILAMENTS IS MAINTAINED BETWEEN 8:2 AND 2:8 RATIOS OUTSIDE SUCH RANGE INVOLVING DIFFICULTIES. ADDITIONALLY, IN USING HEAT TO EFFECT THE CRIMPING, THE TEMPERATURE IS MAINTAINED BETWEEN ABOUT 70* AND ABOUT 150*C.
