Blended yarn spinning technology good in dyeing property

Abstract

The invention discloses a blended yarn spinning technology good in dyeing property. The technology comprises the following steps of blended yarn raw material selection, plasma treatment, bleaching, sizing, modal fiber dyeing, stentering, preshrinking, resultant yarn pretreatment, drafting and sizing. Compared with the prior art, the technology has the advantages that after modal fiber is dyed withdyeing liquor, the yarn has the super light fastness and the property of avoiding color change at high temperature and excellent washing fastness, coloring is easy, and the color is stable. Blended yarn obtained after wool fiber subjected to plasma treatment and the modal fiber are blended can be washed through a washing machine and dried through a roller and is good in fuzzing and pilling resistant property and high in hydrophilia. According to the spinning technology, not only is the dyeing property of the blended yarn improved, but also the blended yarn has the characteristic of the wool fiber, the product quality is improved, and the multi-function use requirements of people are met.

Description

technical field [0001] The invention relates to the field of spinning, in particular to a spinning process of blended yarn with good dyeing performance. Background technique [0002] The traditional all-wool yarn process can no longer meet the functional needs of consumers, but some chemical fibers such as polyester can increase the added value of existing products very well. For example, after the fiber is modified, the capillary phenomenon produced by the micro-grooves on the surface makes the sweat quickly migrate to the surface of the fabric and spread out through absorption, diffusion, transmission, etc., so as to achieve the purpose and effect of moisture-wicking and quick-drying. The fiber after aging only has the function of moisture absorption and perspiration, but does not have the advantages of natural wool, such as warmth retention, soft wool, good elasticity, strong heat insulation, good comfort, not easy to wrinkle, and soft hand feeling, so the scope of use ...
