Abstract

The invention relates to a spinning method for improving the fiber carding straightening parallelism, belonging to the field of spinning processing technology. By adopting a hot-wet pretreatment and multi-level heat treatment mode, the method quickly reduces the modulus and rigidity of the fiber running online on a carding machine, improves the fiber carding straightening parallelism, reduces the fiber damage, improves the impurity removal efficiency of the carding machine, and reduces the noil generated by the flat strips of the carding machine. The method provided by the invention is particularly suitable for treating the textile fiber with high rigidity and elasticity.

Description

Technical field [0001] The invention relates to a spinning method for improving the straightness and parallelism of fiber carding, and belongs to the field of textile processing. technical background [0002] The straightness and parallelism of fibers is one of the important factors affecting yarn quality. One of the main functions of carding is to improve the straightness and parallelism of the fibers in the sliver. The increase in the straightness and parallelism of the fibers is beneficial to combing to reduce noil, which is beneficial to the stability of the fiber shift point during the drafting process, and to improve the yarn evenness. Evenness, yarn strength, yarn hairiness, and improvement of fiber straightness and parallelism are of great significance. [0003] Because the fiber itself has a certain degree of stiffness and hooks, in the process of carding on the carding machine, although the fiber is repeatedly transferred between the two needle surfaces and turned repeat...
