Soft cone spooling process applied to dyeing of cones of viscose filament yarns

Abstract

The invention discloses a soft cone spooling process applied to dyeing of cones of viscose filament yarns. Viscose filament yarns are divided into an inner viscose filament yarn layer, a middle viscose filament yarn layer and an outer viscose filament yarn layer to be spooled on a soft spooling tube to form a soft cone by a soft cone spooler. The end face of the soft cone is inclined at 50 DEG-90 DEG. In spooling, the intersection angle of each two viscose filament yarns is 6 DEG-8 DEG. A spooling arm on the soft cone spooler is perpendicular to a yarn guide roller under the pressure of 150-800g, and the density of the viscose filament yarns on the formed soft cone is 0.3-0.5g/cm<3>. According to the technical scheme and by optimizing and modifying the soft cone spooling process and parameters thereof, the moderate density of the soft cone formed by spooling can be guaranteed, the soft cone is fine in uniformity, and forming of the soft cone is stable.

Description

technical field [0001] The invention relates to a viscose filament dyeing process, more specifically, the invention relates to a loose tube winding process suitable for loose tube dyeing of viscose filament, which belongs to the loose winding dyeing technology in the printing and dyeing industry field. Background technique [0002] The loose tube is the loose winding, the viscose filament is wound on the loose tube, and the viscose filament is formed into a loose tube. , Dyeing, dehydration, drying, and tube forming. The key to the success or failure of loose tube dyeing depends on the density and uniformity of the loose tube formed by winding the viscose filament onto the loose tube. A stable loose tube formed in a package can make the dyeing liquor circulate better. No short-circuit channel is produced, so the research on the loose tube process is very important. [0003] The dye infiltrates into the pine tube in liquid form, the part with high density, the dye solution...

AI Technical Summary

Problems solved by technology

[0009] The present invention aims to solve the problem that the density of loose tubes in the above-mentioned prior art cannot meet the requirements of dyeing, resulting in uneven dyeing, overcomes its defects, and provides a loose tube winding process suitable for dyeing loose tubes of viscose filaments. The optimization and improvement of the winding process parameters of the loose tube makes the density and uniformity of the loose tube of the viscose filament wound out qualified, and the winding is stable and formed, so that the final dyeing is uniform
