Embodiment 1

[0028] Select 100 kg of cotton loose fiber, carry out high-temperature scouring and bleaching before dyeing, and then apply living radical indigo dye, 7% indigo CF-RN and 1% red CF-B (o.w.f, the weight of the fiber, the following are the same), using Dyeing process of reactive dyes, add salt (Yuanmingfen) and soda ash, the temperature is 60 ° C, wash to neutral after dyeing for 40 minutes, and finally add SC202 softener 3g / l and TD color fixing agent 3g / l to soften and fix color treatment to obtain indigo cotton; 50 kilograms of indigo cotton and 50 kilograms of white cotton are blended into AB yarn-style colored spinning; after the colored spinning weaves, 10 g / l potassium permanganate and phosphoric acid (1 : 1) Carry out the monkey treatment to obtain indigo blue denim fabric with partially exposed white and washed old style.

Embodiment 2

[0030] Select 100 kg of cotton loose fiber, carry out high-temperature scouring and bleaching before dyeing, and then apply reactive indigo dye, 8% black CF-G and 1% navy blue C-BR (o.w.f, weight to fiber), and adopt reactive dye dyeing process , add salt (Yuan Mingfen) and add soda ash, the temperature is 70 ℃, wash to neutral after dyeing for 55 minutes, finally add SC202 softening agent 4g / l and TD color-fixing agent 3g / l to carry out softening and color-fixing treatment, obtain Indigo black cotton; 80 kg of indigo black cotton and 20 kg of white cotton are blended to make ordinary mixed color hemp gray yarn; after color spinning and weaving, use 5g / l potassium permanganate and phosphoric acid (1:1) for general washing treatment to obtain a lighter toned, washed-in style black denim.

Embodiment 3

[0032] Select 100 kilograms of viscose bulk fiber for use, apply active radical indigo dye, 6% indigo CF-RN and 1% yellow CF-3R (o.w.f, weight to fiber), adopt reactive dye dyeing process, add salt (yuanming powder) and add Soda ash, the temperature is 50 ℃, after dyeing for 50 minutes, wash with water until neutral, finally add SC202 softener 3g / l and TD color fixing agent 4g / l for softening and color fixing treatment, to obtain indigo viscose; dye indigo viscose 15 kg, 60 kg of white viscose, 25 kg of white cotton, blended to make color-spun yarn with segment color style; after the color-spun yarn is weaved, use 12g / l potassium permanganate and phosphoric acid (1:1) for snowflake washing Indigo denim fabric with light and washed-out effect can be obtained.

Abstract

The invention discloses a making method of colored spun yarn supportive of being used for jean water-washing. The colored spun yarn with specific style is made from active indigo-series dyed fiber andcommon white fiber. Jean fabric with washed-old or locally-washed-white style can be obtained by adopting jean water-washing methods like common washing, snow washing, monkey washing and spraying decoration after the colored spun yarn is woven. The colored spun yarn made by the method is stable and controllable in color depth and color tone, high in friction color fastness and capable of servingas a prime raw material for processing jean knitted casual wear, children's jeans and jean woven garments.

Description

technical field [0001] The invention relates to a method for making colored spun yarn, more particularly to a method for making colored spun yarn that can be used for denim washing. Background technique [0002] Jeans, because of their simplicity, comfort and easy matching, have become a star product that will never leave the market throughout the year. In the prior art, the whole industry (cloth, warp yarn) basically chooses common indigo (reduced type) for denim indigo dyeing. First, the water-insoluble indigo is reduced to a water-soluble leuco with hydrosulfite, and then the warp yarn Or the cloth is padded, exposed to the atmosphere after being rolled out, and the leuco that is soluble in water after air oxidation becomes water-insoluble indigo, and mainly the surface is oxidized, and the dye is concentrated on the surface of the cloth or yarn. Therefore, the rubbing fastness is poor. Even if ordinary indigo is reduced to a leuco, the dyeing performance is very poor, ...
