AI Technical Summary

Problems solved by technology

The breaking strength of ordinary viscose fiber is smaller than that of cotton, about 1.6-2.7 cm / dtex, the elongation at break is 16%-22% higher than that of cotton, and the wet strength drops more, about 50% of the dry strength. The increase is about 50%, its modulus is lower than that of cotton, it is easy to deform under small load, and its elastic recovery performance is poor
Therefore, the fabric is prone to elongation and has poor dimensional stability

Embodiment 1

[0025] This embodiment is a colored blended yarn containing cashmere, the blended yarn includes 50% viscose fiber, 45% mercerized wool fiber and 5% cashmere fiber by weight, and the viscose fiber , mercerized wool fiber, and cashmere fiber, at least one of which is partially or completely dyed fiber, dyed and undyed viscose fiber, mercerized wool fiber, and cashmere fiber are mixed and spun through the spinning process into a colored blended yarn containing cashmere.

Embodiment 2

[0027] On the basis of Example 1, the preferred technical solution of the present invention is that the dyed fiber can dye the fiber into a single color, or it can still be colored, wherein the type and quantity of the dyed fiber account for the majority of viscose. The proportions of fiber, mercerized wool fiber and cashmere fiber in the total amount can be made into color codes according to the requirements of users, and then dyed according to the standard dyeing ratio of color codes.

Embodiment 3

[0029] The preferred technical solution of the present invention also provides a method for processing the colored blended yarn containing cashmere, which is used for processing the above-mentioned colored blended yarn containing cashmere, and the processing method includes the following steps:

[0030] The first step: the dyeing step, dyeing a part or all of at least one fiber of the viscose fiber, mercerized wool fiber, and cashmere fiber, and the type and proportion of the dyed fiber are determined according to the designed color code. set up. The color standard is based on the color required by the customer. First, design and manufacture small samples of A and B. After confirmation by the customer, a sample card is prepared according to the designed color ratio, and a small amount of raw materials are organized to be handed over to the dyeing unit for dyeing according to the sample card.

[0031] The second step: post-dyeing treatment, spray oily water on the dyed merceriz...

Abstract

The invention discloses a colored union yarn containing cashmere and a processing method thereof, wherein the union yarn comprises viscose fibers with weight ratio of 50 %, 45% lustre wool fibers and 5% cashmere fibers, wherein at least part of or the whole of one of the fibers is dyed, the dyed fiber and unfinished fibers are spun into the colored union yarn containing cashmere after mixing through spinning procedures. The process method comprises that dying the fibers, then spraying oil solution on the dyed fibers to stew for tens of hours, and mixing the fibers in different colors and different proportions after weighing, and installing the fibers on a spinning machine to be spun into the colored union yarn. The technical scheme of the invention can reduce the pollution of the dying process to environment, can enrich the color of the union yarn, and reduces the cost required by the finishing process after dying.

Description

technical field [0001] The invention relates to textiles and textile technology, in particular to a colored blended yarn containing cashmere and a processing method thereof. Background technique [0002] In the prior art, blended yarns are all selected from different fibers and spun by spinning machines, and the blended yarns after spinning or the cloth woven by blended yarns generally need to be dyed, and the existing dyeing technology generally needs to be dyed. The spun blended yarn or cloth is 100% dyed. This dyeing method not only wastes water, consumes electricity, but also pollutes the environment, and the cost of dyeing will be high. How to reduce the loss of blended yarn or cloth spun from blended yarn? The pollution caused by dyeing to the environment is a technical problem to be further solved. [0003] Mercerized wool and cashmere fibers have the characteristics of good elasticity, strong moisture absorption, good warmth retention, and not easy to stain, especia...
