Problems solved by technology

[0005] The conventional spunlace dyeing method is paint dyeing, which is easy to operate, but has poor rubbing fastness and is rarely used in clothing.
However, due to the loose structure and poor strength of the spunlaced cloth, when the traditional overflow method, air flow method and continuous method are used for dyeing, due to the impact of large tension and large water flow, it is easy to be broken or have holes. therefore cannot be dyed by these methods

Abstract

A production method of a double-color thread comprises the following steps: firstly, preparing spunlace composite cloth with different fibers on an upper layer and a lower layer, slitting, and dyeing by adopting bobbin dyeing to obtain the double-color thread with different colors on front and back sides. The front side and the back side of the double-color thread produced through the production method of the double-color thread have different colors, a sweater woven by the double-color thread has the good color collision effect, the complex weaving process during weaving of the two threads is avoided, the weaving difficulty is reduced, the weaving efficiency is improved, and meanwhile, the spunlace composite thread is dyed through a bobbin dyeing method, so that the problem that the spunlace cloth is easy to break and hole in a dyeing process is solved.

Description

technical field [0001] The invention belongs to the field of textile engineering, and in particular relates to a production method of a two-color thread. Background technique [0002] Sweaters made of two-color threads are popular because of their unique color contrast effect. The sweater is usually knitted with two threads at the same time, the weaving process is relatively complicated, and the weaving is difficult and the efficiency is low. However, the traditional blended yarn is difficult to achieve a color contrast effect because the two fibers are evenly mixed in the yarn. [0003] Spunlace non-woven fabric is to spray high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength. The obtained fabric is spunlace non-woven fabric. Spunlaced fabric has the characteristics of high strength, soft hand feeling and good drapability. [0004] Spunlace composite fabr...
