Fancy yarn and method of making the same

Abstract

The invention discloses fancy yarn and a manufacturing process thereof. The process comprises the steps of preparing rove-mercerizing the rove or mercerizing the rove and dyeing-drying the rove-spinning. According to the process, real mercerized fibers or mercerized dyed fibers can be produced conveniently through existing devices, the fiber strength of produced mercerized fibers or the fiber strength of produced mercerized dyed fibers is greatly improved, the spinnability of the fancy yarn is greatly improved, the produced fancy yarn is bright and full in color and high in dimensionality of the yarn, the problem that protein fiber yarn which is not alkali-resistant and mercerized fibers can not simultaneously exist in the yarn is solved, the additional value of cotton fibers is greatly improved, and the selection range of consumers is enlarged. The process is easy to implement and can be easily achieved through existing devices, and the probability and the guarantee are provided for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a pure cotton yarn and a manufacturing method thereof. Background technique [0002] Conventional fancy yarn is generally a yarn with special effects obtained by feeding two rovings of different raw materials or two rovings of different colors on the ring spinning machine through drafting and twisting. Generally, different raw materials are used in these yarns, such as acrylic fiber and cotton, polyester and cotton. In this case, the difference in coloring mechanism of different raw materials to dyes can be fully utilized to obtain different color contrasts under the same conditions. , to achieve the effect of fancy yarn, which is often called AB yarn. However, with the improvement of people's living standards, consumers are more inclined to choose natural fiber products, and pure cotton is still their first choice. [0003] There are generally two ways to produce ...

Problems solved by technology

The second method is to cationic modify the raw material of one of the rovings, prepare it into a roving and feed it into the drafting zone together with another ordinary cotton roving, and make it look normal on the surface after being drawn and twisted. This white yarn is the same as the yarn, but after dyeing, there will be differences in the adsorption of dyes between the cationic modified cotton fiber and the normal cotton fiber, and finally the yarn will show different shades of color, and the boundaries are clear

[0004] However, there are still some regrets in the above two methods. In the first method, the raw materials must be dyed, and then prepared into the required roving. After the cotton fiber is dyed, the wax on the fiber surface is removed, although it will be lubricated to a certain extent. However, since the strength will be reduced to a certain extent after dyeing, and the process of dyeing cotton loose fibers is relatively complicated, the production difficulty is significantly increased in the actual production process.

In the second method, although the raw material of one of the rovings is cationic treated before spinning, and the coloring difference between the cotton fiber after cationic treatment and ordinary cotton fiber is used to achieve the desired effect, the raw cotton of one of the rovings must be in the bulk. Cationic treatment at the fiber stage still needs to go through some necessary processes of dyeing cotton, which will still damage the strength of cotton fibers to a certain extent, and the cotton wax on the surface will also be removed, so the problems of method 1 also exist, and at the same time Cationic treated cotton fibers occasionally have a characteristic odor

[0005] Therefore, the above two methods not only have complicated processes, but also cause great damage to cotton fibers, have high requirements on the spinning process, and have poor spinnability.
