Problems solved by technology

Because the fiber will carry a certain negative charge due to hydrolysis in the aqueous solution, it is difficult for the dye anion to penetrate deep into the fiber, so the dye uptake rate is not high enough and a large amount of electrolyte is required to promote dyeing. The dyeing wastewater contains high concentrations of dyes and salts. seriously pollute the environment

Embodiment 1

[0019] Select 100 kg of cotton loose fiber, after conventional scouring or pre-bleaching, put it into a bath ratio of 1:10, containing 18 g / L quaternary ammonium cationic etherification agent, 6 g / L caustic soda solution, and heat up to After soaking at 85°C for 50 minutes, wash with dilute acetic acid and water until neutral. Mix 10% / 20% / 40% / 60% / 85% cationic modified cotton with 90% / 80% / 60% / 40% / 15% bleached cotton fiber evenly and spin in normal style, it can be Cationic cotton yarns with a modified ratio of 10% / 20% / 40% / 60% / 85% were prepared, and were woven into white interstripe cloth incrementally according to the modified ratio (10:20:40:60:85). The white inter-stripe cloth should be dyed with brilliant blue reactive dye KN-R under neutral and salt-free conditions, and the fancy yarn inter-stripe cloth with blue shade effect can be obtained.

Embodiment 2

[0021] Select 100 kg of Modal loose fiber, after conventional scouring pre-treatment, put it into a bath ratio of 1:11, containing 15 g / L quaternary ammonium cationic etherification agent, 10 g / L caustic soda solution, and heat up to 65 °C After soaking for 60 minutes, wash with dilute acetic acid and water until neutral. Mix 20% / 40% / 70% / 95% cationic modified modal with 80% / 60% / 30% / 5% white modal and spin them in the style of slub yarn to get 20% / 40% / 70% / 95% cationic modal yarn with modified ratio (20:70:95:40) is woven into white interstripe cloth. The white interstripes should be dyed with red acid dye Erionyl under salt-free conditions, and the interstripes with fancy yarn slub effects of red shades can be obtained.

Embodiment 3

[0023] Select 100 kg of tencel loose fibers, put them into a bath ratio of 1:15, contain 20 g / L quaternary ammonium cationic etherification agent, 7 g / L caustic soda solution, heat up to 70 °C and soak for 80 minutes, then use dilute acetic acid and Wash to neutral. Mix 5% / 15% / 35% / 50% cationic modified tencel with 95% bleached cotton / 85% modal / 30% tencel and 35% cotton / 50% bleached cotton, and 50% of the modified tencel Tencel and 50% bleached cotton are spun in the AB yarn style, and the multi-fiber component yarn of cationic modal with a modification ratio of 5% / 15% / 35% / 50% can be obtained, and the modification ratio (15: 35:5:50) into white striped cloth. The white interstripe cloth should be dyed with yellow-brown direct dye D3G under neutral and salt-free conditions to obtain fancy yarn interstripe cloth with yellow-brown shade effect.

Abstract

The present invention discloses process of producing fancy yarn stripe cloth in tone-in-tone effect. The production process includes the first weaving of white stripe cloth with different cation modified yarns in different ratios and different styles, and the subsequent dyeing of the white stripe cloth. Through once dying, the white stripe cloth may be dyed into special tone-in-tone cloth, and thus produced fancy yarn stripe cloth in tone-in-tone effect is high grade material for making high grade underwear, T shirts, casual wear, etc.

Description

1. Technical field [0001] The invention relates to a method for making fancy yarn inter-stripes with the same color shade effect, more specifically, it relates to weaving cationic modified yarns with different proportions and different spinning styles into white interstripes according to the set sequence. Cloth, and then the method of dyeing the white striped cloth. 2. Background technology [0002] Cellulose fibers are usually dyed with anionic dyes, such as reactive dyes, direct dyes, acid dyes or soluble vat dyes. Because the fiber will be negatively charged due to hydrolysis in the aqueous solution, it is difficult for the dye anion to penetrate deep into the fiber, so the dye uptake rate is not high enough and a large amount of electrolyte is required to promote dyeing. The dyeing wastewater contains high concentrations of dyes and salts. Seriously pollute the environment. This can be improved by cationic modification of the cellulose fibers. [0003] Cellulosic fibe...
