Functional terylene modified fiber mixed-color yarn and preparation technique thereof

Abstract

The present invention relates to a functional polyester modified fiber mixed-color spinning yarn and the preparation method thereof. The present invention discloses a functional polyester modified fiber mixed-color spinning yarn, which is characterized in that: the functional polyester modified fiber is in a honeycomb-shaped micropore structure, and the content of the functional polyester modified fiber is 35-100 percent. The present invention further discloses the preparation method of the functional polyester modified fiber mixed-color spinning yarn as well. The mixed-color spinning yarn of the present invention is good in the absorption property of perpendicular core and greatly superior to the indexes of equivalent fabrics under Invista standard. The corresponding products of the present invention is more comprehensive in comfort healthy nursing care to human bodies, good in product washability, durable in performance and all-around in bactericidal function.

Description

technical field [0001] The invention relates to a functional polyester modified fiber melange spinning yarn and a preparation method thereof. Background technique [0002] In the field of color spinning, because the fibers are dyed first and then spun, there are dyed polyester and natural polyester in the yarn and fabric. At present, polyester loose fiber dyeing, no matter domestic or imported disperse dyes such as Ciba, Klein, Desta, etc. , or high-performance special disperse dyes, neither can solve the color fastness of dyed textiles at 170 ° C low temperature setting, or 190 ° C ~ 210 ° C high temperature setting T / C, CVC fabric setting color fastness, sublimation fastness, dyed polyester and natural color polyester The obvious color change problem of the fabric caused by the heat transfer dyeing between the fabrics, generally can only maintain the color fastness of grade 4 or above at 150 ° C or below, but at this temperature, the dyed polyester fabric cannot be effec...

AI Technical Summary

Problems solved by technology

[0006] At present, there is no color-spun product of functional polyester fiber with honeycomb microporous structure on the market. During the exploration of the color-spinning process of this product, technicians found that when the fiber is blended with a high proportion or 100% pure spinning, because of its special The honeycomb structure leads to a large friction coefficient on the surface of the fiber, which is reflected in the poor spinnability of the upper machine after the fiber is dyed. The fiber is stuck on the cover plate on the carding machine, and the cotton is not cleaned by the cutting knife; the fiber is wound around the cylinder, and the sliver is lowered Unsmooth; Phenomena such as winding top rollers and rollers on the draw frame occur from time to time, making it difficult to obtain qualified color spinning products
