Problems solved by technology

However, in the preparation process of colored spinning yarn, the elasticity and friction coefficient of cotton are reduced after dyeing, boiling and bleaching, and the spinnability is reduced, so it is difficult to prepare high-count yarn.
In addition, the existing production process of colored spinning starts from cotton dyeing, first dyes the corresponding cotton according to each color, t

Example Embodiment

[0022] Example 1

[0023] A processing method for producing gray-blue colorful mercerized spun yarn with a raw material ratio of "5% yellow cotton + 5% red cotton + 90% natural cotton", including the following processing steps:

[0024] 1. Yellow cotton and red cotton dyeing

[0025] Dye yellow and red cotton respectively on the loose fiber dyeing machine, and ensure uniform dyeing by controlling the amount of dye, the amount of salt and alkali, and the fixing time. The dye concentration is 0.5-1% (owf), the salt dosage: 20-30g / L, the alkali dosage is 10-20g / L, and the time is 45min.

[0026] 2. Cotton blending

[0027] According to the weight ratio of 5:5:90, the yellow, red, and natural cotton are piled on the opener and mixed with cotton, so that the fibers of various colors are distributed in each part of the yarn.

[0028] 3. Spinning

[0029] The spinning process of carding, drawing, roving, spun yarn, and doubling should adopt a spinning process with light weight, slow spee...

[0038] Example 2

[0039] A processing method for producing red-purple colorful mercerized yarn with a raw material ratio of "8% blue cotton sliver + 92% boiled and bleached cotton sliver" includes the following processing steps:

[0040] 1. Blue cotton fiber dyeing

[0041] Dye blue cotton on the loose fiber dyeing machine, and ensure uniform dyeing by controlling the amount of dye, the amount of salt and alkali, and the fixing time. The dye concentration is 0.5-1% (owf), the salt dosage: 20-30g / L, the alkali dosage is 10-20g / L, and the time is 45 minutes.

[0042] 2. Natural cotton scouring and bleaching

[0043] Wash and bleach on the loose fiber dyeing machine, add 5.5g / l hydrogen peroxide, 1.5g / l 50% caustic soda, 1.5g / l multifunctional refining agent, temperature 98℃, time 45 minutes.

[0044] 3. Blending

[0045] According to the weight ratio of 8:92, the blue cotton and the boiled and bleached cotton are piled and mixed on the open-cleaner, so that the fibers of various co...

[0056] Example 3

[0057] A processing method for producing blue-black colorful mercerized yarn with a raw material ratio of "7% black cotton + 93% natural cotton", including the following processing steps:

[0058] 1. Black cotton dyeing

[0059] Dye black cotton on the loose fiber dyeing machine, and ensure uniform dyeing by controlling the amount of dye, the amount of salt and alkali, and the fixing time. The dye concentration is 0.5-1% (owf), the salt dosage: 20-30g / L, the alkali dosage is 10-20g / L, and the time is 45min.

[0060] 2. Cotton blending

[0061]According to the weight ratio of 7:93, the black cotton and the natural color cotton are piled on the open-cleaner to mix the cotton, so that the fibers of various colors are distributed in each part of the yarn.

[0062] 3. Spinning

[0063] Carding, drawing, roving, spun yarn, and doubling procedures should adopt a light weight, slow speed, and easy to transfer spinning process. Generally, the weight is controlled and the...

Abstract

The invention relates to a processing method for colorful mercerized spun-dyed yarns, which comprises the following steps: cotton dying, namely selecting a certain amount of cotton respectively and dying the cotton with various reference colors; cotton mixing, namely one or more types of cotton which is dyed with the reference colors is mixed with cotton with natural color according to the requirement and the proportion; spinning; mercerization; and yarn dying. In the working procedure of the cotton dying, a small amount of cotton is only dyed with a plurality of specific reference colors, yarns with different color systems can be combined freely by yarn re-dying, and manufacturers can prepare goods more conveniently and purposely, and accelerate the production flow of the spun-dyed yarns; in the working procedure of the cotton mixing, a small amount of the cotton dyed with the reference colors is mixed with a large amount of the cotton with the natural color so as to reduce the phenomena of reducing the spinnability possibly caused by cotton dying, and high count yarns can be spun; the working procedure of yarn dying is added after the spinning work procedure, and the yarns are dyed into various colorful spun-dyed yarns by dying; and the addition of the mercerization work procedures makes the colors of the spun-dyed yarns more colorful.

Description

technical field [0001] The invention relates to a processing method of colored spun yarn, in particular to a deep processing method of colored spun yarn with bright colors and fibers of various colors. Background technique [0002] Color spun yarn is generally a yarn made by mixing two or more fibers of different colors. The fabric made of color spun yarn has a hazy and natural color, which is very popular among consumers. However, during the preparation process of colored spinning yarn, the elasticity and friction coefficient of cotton are reduced after being dyed, boiled and bleached, and the spinnability is reduced, so it is difficult to prepare high-count yarn. In addition, the existing production process of colored spinning starts from cotton dyeing, first dyes the corresponding cotton according to each color, then blends the cotton, and then spins the yarn. It takes at least 40 days from cotton dyeing to yarn production. The time and long production cycle are not suit...
