Embodiment 1

[0021] A kind of raw material ratio is " 5% yellow cotton + 5% red cotton + 90% uncolored cotton " the processing method of producing gray-blue multi-color spinning yarn, comprising the following processing steps:

[0022] 1. Dyeing of yellow cotton and red cotton

[0023] Dye yellow and red cotton separately on the bulk fiber dyeing machine, and ensure uniform dyeing by controlling the amount of dye, saline and alkali, and color fixing time. The dye concentration is 0.5-1% (owf), the dosage of salt is 20-30g / L, the dosage of alkali is 10-20g / L, and the time is 45min.

[0024] 2. Cotton blending

[0025] According to the weight ratio of 5:5:90, the yellow, red, and natural color cotton are piled up on the cotton opening and cleaning machine and mixed, so that the fibers of various colors are distributed in various parts of the yarn.

[0026] 3. Spinning

[0027] The process of carding, drawing, roving, spun yarn, and doubling should adopt the spinning process with light wei...

Embodiment 2

[0035] A processing method for producing reddish-purple multi-color spinning yarn with a ratio of raw materials of "8% blue cotton sliver bucket 92% boiled and bleached cotton sliver", comprising the following processing steps:

[0036] 1. Blue cotton fiber dyeing

[0037] The blue cotton is dyed on the bulk fiber dyeing machine, and the uniformity of dyeing is ensured by controlling the amount of dye, the amount of saline and alkali, and the color fixing time. The dye concentration is 0.5-1% (owf), the amount of salt: 20-30g / L, the amount of alkali 10-20g / L, and the time is 45 minutes.

[0038] 2. Natural color cotton boiled and bleached

[0039] Wash, boil and bleach on the loose fiber dyeing machine, add hydrogen peroxide 5.5g / l, 50% concentration caustic soda 1.5g / l, multifunctional refining agent 1.5g / l, temperature 98 ℃, time 45 minutes.

[0040] 3. Cotton blending

[0041] According to the weight ratio of 8:92, the blue cotton and the boiled and bleached cotton are p...

Embodiment 3

[0051] A processing method for producing blue-black multi-color spinning yarn with a ratio of raw materials of "7% black cotton + 93% natural color cotton", comprising the following processing steps:

[0052] 1. Black cotton dyeing

[0053] Black cotton is dyed on a bulk fiber dyeing machine, and uniform dyeing is ensured by controlling the amount of dye, saline and alkali, and color fixation time. The dye concentration is 0.5-1% (owf), the dosage of salt is 20-30g / L, the dosage of alkali is 10-20g / L, and the time is 45min.

[0054] 2. Cotton blending

[0055] According to the weight ratio of 7:93, the black cotton and the natural color cotton are piled up on the cotton opening and cleaning machine to mix the cotton, so that the fibers of various colors are distributed in various parts of the yarn.

[0056] 3. Spinning

[0057] The process of carding, drawing, roving, spun yarn, and doubling should adopt the spinning process with light weight, slow speed and easy transfer. ...

Abstract

The invention relates to a processing method for colorful 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; and yarn dying, namely according to the color matching, the spun yarns are dyed to reach the required colors. 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; and 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.

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 containing 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 suitable for the...
