Abstract: The present invention relates to a crimped polyester conductive filament, a manufacturing method and an application thereof. The crimped polyester conductive filament is obtained by subjecting a polyester conductive filament to a crimping deformation process, and has a crimp shrinkage of 15%-60% and a crimp stability of 40%-90%. The process of deformation processing is as follows: the conductive fiber protofilament is heated and plasticized by a deformed hot-box, cooled by a cooling plate, twisted and untwisted by a false twister, shaped, added with interlaced nodes, oiled, wound, inspected, and packaged. The crimped polyester conductive filament is beneficial to the subsequent blended weaving, or used alone for weaving, and can exhibit a soft human experience effect, and can be widely used in smart wear and other fields.

Abstract: The present invention relates to a crimped polyamide conductive filament, a manufacturing method and an application thereof. The crimped polyamide conductive filament is obtained by subjecting a conductive fiber with composite structure prepared by melt composite spinning process to a crimping deformation process, and has a crimp shrinkage of 15%-60% and a crimp stability of 40%-90%. The process of deformation processing is as follows: the conductive fiber protofilament is heated and plasticized by a deformed hot-box, cooled by a cooling plate, twisted and untwisted by a false twister, shaped, added with interlaced nodes, oiled, wound, inspected, and packaged. The crimped polyamide conductive filament is beneficial to the subsequent blended weaving, or used alone for weaving, and can exhibit a soft human experience effect, and can be widely used in intelligent sensing, smart wear and other fields.
