Problems solved by technology

However, when treated with strong alkali and high temperature water, the reactive dyes in the dyed cotton will break bonds, hydrolyze or decolorize to varying degrees, and the dyes falling in the water will contaminate the white cotton components, resulting in the main color of the dyed cotton. Severe color cast or light color
Even if the lye concentration is reduced to the greatest extent under the premise of ensuring the solubility of polyester, or the mercerizing reactive dye with good alkali resistance is selected and supplemented with alkali-resistant color fixing agent, there are only different degrees of improvement, but the performance of color spinning The color is still fluctuating greatly, and the shade and quality are difficult to control, which restricts the promotion progress of hollow thermal cotton color spinning

Embodiment 1

[0017] Select 15 kilograms of Solucell fiber, 20 kilograms of cationic modified cotton, and 65 kilograms of white cotton, and blend them into AB yarn style core-spun yarn. The core-spun yarn is pre-treated with high-alkali solution at high temperature. The process parameters are: caustic soda 5 g / L, GSF5528 refining agent 1 g / L, liquor ratio 1:6, 95°C treatment for 40 minutes; pickling after alkali boiling For neutralization, the process parameters are: 3 g / L acetic acid, 40°C for 20 minutes; after dissolving the Solucell component, hollow cotton yarn is obtained. Then use ordinary yellow reactive dye 3RF to dye, and do not add salt and alkali in the dyeing bath, so that the hollow thermal cotton yarn with yellow and white mixed color effect can be obtained.

Embodiment 2

[0019] Select 18 kilograms of Solucell fiber, 15 kilograms of cationic modified cotton, and 67 kilograms of white cotton, and blend them into common core-spun yarns. The core-spun yarn is pre-treated with high-alkali solution at high temperature. The process parameters are: caustic soda 7 g / L, GSF5528 refining agent 0.5 g / L, liquor ratio 1:10, 98°C treatment for 45 minutes; pickling after alkali boiling Neutralization, the process parameters are: 2 g / L acetic acid, 35 ° C for 25 minutes; dissolve the Solucell component to obtain a hollow cotton yarn. Dyeing with ordinary red reactive dye 3BF, without adding salt in the dyeing bath, adding 5g / l soda ash, can get red and light red hollow thermal cotton yarn with mixed color effect.

Embodiment 3

[0021] Select 25 kg of Solucell fiber, 40 kg of cationic modified cotton, and 35 kg of white cotton, and blend them into a core-spun yarn in the style of the idea. The core-spun yarn is pre-treated with high-alkali solution at high temperature. The process parameters are: caustic soda 10 g / L, GSF5528 refining agent 2 g / L, bath ratio 1:8, 110°C treatment for 30 minutes; pickling after alkali boiling For neutralization, the process parameters are: 1 g / L acetic acid, 45°C for 15 minutes; after dissolving the Solucell component, hollow cotton yarn is obtained. The hollow yarn is bleached with hydrogen peroxide at high temperature, and then dyed with a brilliant blue reactive dye KN-R. No salt and alkali are added in the dyeing bath, and a hollow thermal cotton yarn with a brilliant blue and white mixed color effect can be obtained.

Abstract

The invention discloses a method for producing a colored spun yarn of hollow warm-keeping cotton. The method is characterized in that soluble terylene, cation modified cotton fiber, and common white cotton fiber are used to prepare core-spun yarn having a specific style, the above core-spun yarn employs high alkali lye for high-temperature pre-treatment, a soluble terylene component is dissolved,the hollow warm-keeping cotton yarn can be obtained, and the colored spun yarn style can be dyed by using a reactive dye. The hollow warm-keeping cotton has the advantages of stable and controllable color depth and colored light, the yarn is hollow, soft, fluffy and warm, and can be used as a good raw material for processing high-grade underwear, T shirt, and leisure wear.

Description

technical field [0001] The present invention relates to a method for manufacturing colored spun yarn, more particularly to a method for manufacturing hollow thermal cotton colored spun yarn. Background technique [0002] The traditional method of hollow thermal cotton color spinning is to mix soluble polyester with dyed cotton and white cotton and spin it into core-spun yarn, and then treat it with strong alkali at high temperature to completely dissolve the soluble polyester component in the yarn, leaving only The lower cotton component, so as to give the yarn hollow and warm properties. However, when treated with strong alkali and high temperature water, the reactive dyes in the dyed cotton will break bonds, hydrolyze or decolorize to varying degrees, and the dyes falling in the water will contaminate the white cotton components, resulting in the main color of the dyed cotton. Severe color cast or light color. Even if the lye concentration is reduced to the greatest exte...
