Title:
METHOD AND EQUIPMENT FOR COMPOSITE SPINNING OF FILAMENT AND STAPLE FIBER, AND COMPOSITE YARN
Document Type and Number:
WIPO Patent Application WO/2020/097849
Kind Code:
A1
Abstract:
A method and equipment for composite spinning of a filament and a staple fiber, and a composite yarn (9). The equipment comprises: a filament tension control device (3) provided in front of a front roller (8) and configured to control the tension of a filament (1); and a filament position control device (4) provided between the front roller (8) and the tension control device (3) and configured to control the position of the filament (1), wherein the surface of the filament position control device (4) is provided with a grooved drum type trench, and the filament (1) is reciprocated left and right by means of the rotation of a guide wheel, or a yarn guide wheel (2) of the device can reciprocate and feed the front roller (8) in a dynamic form. Based on the filament tension control and the feeding cooperation effect at a dynamic position, in the resultant yarn, part of the filament is wrapped on the surface of the yarn, and part of the filament is buried in the yarn body, thereby forming a staple fiber and filament composite structure and a composite yarn (9). The composite yarn (9) processed using the method and equipment has strong cohesion of a filament and a staple fiber, significantly reduced yarn hairiness, and high strength; the knitted fabric thereof has excellent pilling resistance, weak wool-evoked prickle sensation, good handle, and stable dimension.
