Abstract

The invention relates to a colored filament yarn spinning device for imitation cotton fabrics and a filament yarn processing method thereof, which comprises, from left to right, a front roller, a middle roller, a pressure roller and a rear roller, and the middle rollers are covered with leather The pressure roller and the apron are respectively wrapped with emery leather, the wrapping angle of the lower pressure roller and the filament is 45-90 degrees, the wrapping angle of the upper pressure roller and the filament is 0-45 degrees, and the upper pressure roller The mesh number of wrapped emery leather is greater than that of the wrapped emery leather of the lower pressure roller. The method is: feed the multifilament composed of polyester colored filaments with a specified ratio to the entrance of the spinning device, and the sliver passes through the rear roller, pressure roller, middle roller and front roller of the drafting mechanism of the spinning device in sequence. . The invention improves the ring spinning technology and spins the polyester filament yarn with cotton yarn feel, so that the product has the cotton feel and the durability and mechanical strength of chemical fiber, and can shorten the production time compared with the traditional cotton imitation long yarn process. processes and cycles.

Description

Technical field [0001] The invention belongs to the technical field of processing filament-like cotton fabrics, and particularly relates to a colored filament yarn spinning device for cotton-like fabrics and a filament yarn processing method thereof. Background technique [0002] The colored spun yarn produced by mixing and spinning in a specific process has a three-dimensional mixed color style due to the yarn containing two or more different colored fibers. Different from the traditional production method of "spinning first and then dyeing" in the traditional spinning process, the processing mode of "first dyeing and then spinning" of dyed yarn makes the fabric no longer need to be dyed and finished. In the production process, compared with traditional cheese dyeing and fabric dyeing products, dyed spun yarn products can shorten the processing procedure and reduce environmental pollution; in terms of product effect, due to the difference in shrinkage or coloration of various fi...
