Spontaneously crimping synthetic composite filament and process of manufacturing the same
Abstract
Abstract A SPONTANEOUSLY CRIMPING SYNTHETIC COMPOSITE FILAMENT HAVING SILK-LIKE HAND FEEL AND SHEEN COMPRISES AT LEAST TWO SYNTHESIS POLYMERIC FILAMENTARY CONSTITUENTS WHICH ARE DIFFERENT FROM EACH OTHER AND ECCENTRICALLY INCORPORATED INTO A FILAMENT BODY AND HAS A FINENESS NOT EXCEEDING 2.0 DENIER. THE COMPOSITE FILAMENT IS MANUFACTURED USING A PROCESS COMPRISING (1) PREPARING A PLURALITY OF COMPOSITE STREAMS EACH OF WHICH IS CMPOSED OF AT LEAST TWO POLYMERIC CONSTITUENTS STREAMS ECCENTRICALLY INCORPORATED, (2) UNITING THE COMPOSITE STREAMS WITH A POLYMERIC STREAM INTO A COMPLEX CONJUGATE STREAM IN WHICH THE UNITING STREAM FILLS UP SPACES BETWEEN THE COMPOSITE STREAMS, (3) SPINNING THE COMPLEX CONJUGATE STREAM INTO A FILAMENT FORM, AND (4) REMOVING THE UNITING CONSTITUENT IN ORDER TO OBTAIN THE COMPOSITE FILAMENTS. THE INVENTION INCLUDES A COMPLEX CONJUGATE FILAMENT INTERMEDIATELY OBTAINED IN THE ABOVE-STATED PROCESS. THE COMPLEX CONJUGATE FILAMENT IS COMPOSED OF A PLURALITY OF COMPOSITE FILAMENTARY SEGMENTS AND A UNITING CONSTITUENT WHICH IS REMOVABLE.
