Embodiment 1

[0047] The method for producing colored spinning yarn in the present embodiment may further comprise the steps:

[0048] 1. Spinning of A:

[0049] According to the product requirements, dye the cotton fiber of strip A to make the fiber reach the required black color. A small amount of mixing is carried out in several groups with white cotton at a ratio of 50% in color ratio. After the raw materials are mixed, in the cleaning process, the cleaning machine is FA002-FA035E-FA106-FA076-A092A, which further mixes various raw materials of different colors and properties and quantitatively forms them into rolls. The dry weight of cotton rolls is 420 g / m, lap length 37m. On the FA201B carding machine, the colored cotton laps are carded into slivers, and the raw sliver dry weight is 20.5 g / 5 m, and then doubled into 20.5 g / 5 m by the FA317 drawing frame.

[0050] 2. Spinning of B:

[0051] Select uncolored cotton for a small amount of mixing in several groups. After the raw mater...

Embodiment 2

[0086] 1. In the spinning step of A, the quantitative amount of A is 13 grams / 5 meters;

[0087] 2. In the spinning step of B, the quantification of B is 13 grams / 5 meters;

[0088] 3. The weight of final drawing frame in final drawing spinning is 13g / 5m;

[0089] 4. The roving weight in the roving process is 4.1 g / 10 meters; the twist coefficient is 80.

[0090] Others are the same as embodiment 1.

Embodiment 3

[0092] 1. In the spinning step of A, the quantitative amount of A is 26 grams / 5 meters;

[0093] 2. In the spinning step of B, the quantification of B is 26 grams / 5 meters;

[0094] 3. The weight of final drawing frame in final drawing spinning is 26g / 5m;

[0095] 4. In the roving process, the roving weight is 7.0 g / 10 meters; the twist coefficient is 120.

[0096] Others are the same as embodiment 1.

Abstract

The invention discloses a method for producing a colored spun yarn. Two raw material fibers in different colors are successively subjected to cotton grabbing, cotton blending, cotton slitting, coiling, cotton carding, first drawing and second drawing, and then are prepared into two merged strips, namely, a strip A and a strip B; the strip A and the strip B are subjected to a ail strip drawing process, a roving process and a spinning process, and then are prepared into the yarn. According to the method provided by the invention, a drawing frame device used for tail drawing is novel in structure; the distribution along the cross section direction of cotton strips after blending is uneven; the thickness change and the color change along the longitudinal direction of the cotton strips are obvious; the surface of a fabric made from the cotton strips is uneven; with the strip-shaped effect, the fabric has a three-dimensional color comparison effect.

Description

technical field [0001] The invention relates to the field of spinning technology, in particular to a drawing method for producing colored spinning yarn. Background technique [0002] Color-spun yarn is already a very popular product, while conventional color-spun yarn is basically the same color in the direction of the yarn length, and the fabrics woven from such yarns give people a monotonous visual effect. With the improvement of the living standards of the masses, the acceleration of the pace of life, and the increase of the pressure of life, people are more strongly uttering their own voices, showing their own personality, and reflecting their own existence. Therefore, those textiles that are different from others and embody individuality are favored by consumers. [0003] The function of the drawing frame is to improve the internal structure of the sliver, thereby improving the uniformity of its long segments, and at the same time reducing the unevenness of the weight,...
