Embodiment 1

[0019] The mandarin duck color spinning yarn of embodiment 1 "5% red / 10% blue"

[0020] Dyeing treatment of combed cotton sliver: first put the combed cotton sliver in a cage, add it to the scouring enzyme aqueous solution with a concentration of 1g / L, soak it for 20 minutes at a temperature of 50°C, wash the combed cotton sliver, and then The combed cotton sliver is dyed red and blue respectively with medium temperature reactive dyes. The dyeing process conditions for the red combed cotton sliver are as follows: the amount of red 3RS is 3% of the mass of the combed cotton sliver, the temperature is 60°C, and the dyeing process is The time is 45 minutes; the dyeing process conditions of blue combed sliver are: the consumption of blue RXN is 2.5% of the quality of combed sliver, the temperature is 60°C, and the coloring time is 45 minutes. The concentration of sodium chloride is 40g / L, and the concentration of sodium carbonate is 15g / L. The dyed red or blue combed cotton slive...

Embodiment 2

[0025] The alkali-resistant and mercerized mandarin duck colored spinning yarn of embodiment 2 "15% yellow / 80% gray"

[0026] Dyeing treatment of carded sliver: first put the carded sliver in a cage, add the scouring enzyme aqueous solution with a concentration of 2g / L, soak the carded sliver for 40 minutes at a temperature of 60°C, wash the carded sliver, and then use High-temperature reactive dyes dye carded cotton sliver into yellow and gray respectively. The dyeing process conditions for yellow cotton sliver are: the amount of yellow H-E4R is 4% of the mass of carded cotton sliver, the temperature is 80°C, and the coloring time is 55 minutes, the concentration of sodium chloride in the dyeing liquor is 60g / L, and the concentration of sodium carbonate is 20g / L; the gray cotton sliver dyeing process conditions are: the amount of yellow ESL is 0.8% of the mass of carded cotton sliver, and the amount of red ESL is 0.8% of the mass of carded cotton sliver. 1.2% of the mass of t...

Abstract

The invention belongs to the field of colored spun yarns and provides a production method of two-color spun yarns. The production method is characterized in that a dying process of fibers including: treating the fibers by scourzyme, regulating the temperature thereof to the dyeing temperature after washing the fibers, then dyeing and drying the fibers; drawing natural-colored fibers and fibers dyed in different colors respectively to form rovings in different colors, processing two rovings in different colors to be two-color colored fine yarns by means of sirospun spinning, and finally twisting the two-colored fine yarns to obtain two-colored spun yarns. By means of sirospun spinning, the two-colored spun yarns different in colors are realized by single yarn, the two-color spun yarns can be used for knitted fabric or woven fabric without being dyed, and the production method is free of pollution during use and color difference can be controlled to the greatest extent.

Description

technical field [0001] The invention belongs to the field of colored spinning yarns, and in particular relates to a method for processing two different colored spinning rovings into mandarin duck colored spinning yarns. Background technique [0002] Color spun yarn is made by fully mixing two or more fibers of different colors, and it is a yarn with unique color mixing effect. Fibers of different colors adopt a variety of mixed spinning methods to present natural and fashionable colors, soft and warm tones, and the woven fabrics have a hazy three-dimensional effect, and the spun yarns can be directly used for knitting without dyeing. fabric or woven fabric, use without pollution, and at the same time control the color difference to the greatest extent. The existing color spinning is generally processed by ring spinning, which is relatively fixed and mature, that is to process a hemp gray roving into a spun yarn, and then twist it into a single yarn, but this process cannot ...
