Problems solved by technology

However, the cotton fiber after traditional dyeing and finishing process contains more hydrophobic oil agents, which greatly reduces the hygroscopicity of cotton, so the hydrophilicity of ordinary cotton color spinning yarn is gener

example 1

[0020] Example 1 (original white)

[0021] Select 100 kg of cotton loose fiber, put it into a solution with a bath ratio of 1:8 at room temperature, scouring enzyme Novozyme 301L 1%, cellulase L 1%, penetrant 1%, adjust the pH to 4.8 with HAC, and treat it at 55°C for 20 Add 8 g / L caustic soda to raise the temperature to 90°C, soak for 30 minutes, neutralize with acetic acid and wash with water until neutral. After treatment, add 5% hydrophilic soft oil 3098, 3% penetrant JFC, adjust the pH to 5.5 with HAC, bath ratio 1:8, immerse at 60°C for 30 minutes, then directly dehydrate and dry. The cotton produced by this method feels fluffy, soft and smooth, and has excellent water absorption. The vertical wicking height of the fabric woven by using it exceeds 15cm in 30 minutes.

example 2

[0022] Example 2 (bleaching)

[0023] Select 100 kilograms of cotton loose fibers for use, and put it into a bath ratio of 1:15 and contain 1 g / liter of chelating dispersant WA solution (soft water effect) at normal temperature, scouring enzyme 301L1%, cellulase L, penetrant JFC 1 %, adjust the pH to 4.8 with HAC, add 10 g / L of caustic soda and 8 g / L of hydrogen peroxide after 30 minutes of treatment at 50°C, soak for 40 minutes, neutralize with acetic acid and wash with water until neutral. After treatment, add hydrophilic soft oil Shuanghong 3098 5%, penetrant JFC 3%, adjust pH to 5.5 with HAC, bath ratio 1:8, soak at 60°C for 30 minutes, dehydrate directly, and dry. The cotton produced by the method of the invention feels fluffy, soft and smooth, and has excellent water absorption, and the vertical wicking height of the fabric woven by using the method exceeds 15cm in 30 minutes.

example 3

[0024] Example 3 (whitening or dyeing)

[0025] Select 140 kilograms of cotton sliver loose fibers for use, and put it into a solution with a bath ratio of 1: 10 and 2 g / liter of chelating dispersant CT powder (soft water effect) at normal temperature, scouring enzyme 301L1%, cellulase L penetrating agent JFC 1%, use HAC to adjust the pH to 4.8, treat at 50°C for 40 minutes, add 10 g / L caustic soda at 80°C, soak for 40 minutes, neutralize with acetic acid and wash with water until neutral. After adopting conventional cotton loose fiber dyeing process, carry out post-treatment, add Ciba ULTRAPHIL DCW, penetrating agent is 3%, adjust pH to 5.5 with HAC, bath ratio 1:10, soak at 50°C for 30 minutes, dehydrate directly, and dry . The cotton produced by the method of the invention feels fluffy, soft and smooth, and has excellent water absorption, and the vertical wicking height of the fabric woven by using the method exceeds 15cm in 30 minutes.

Abstract

A treatment to make cotton fiber more hygroscopic .The process includes enzyme treatment on cotton fiber to enhance its smoothness and strength, dyeing on fiber, softening agent treatment to make it more hygroscopic and to lower its specific resistance. Cotton made by this process shows high quality such as softy, smoothy and hygroscopic. It is also time saving and energy saving.

Description

technical field [0001] The invention relates to a finishing method of high moisture-absorbing and perspiration-releasing cotton loose fibers, in particular to a functional finishing method of cotton fibers. Background technique [0002] With the improvement of people's life and the improvement of consumption level, fabrics must not only maintain the characteristics of anti-wrinkle, non-ironing, easy-washing, and quick-drying, but also have a bright and light appearance and comfortable wearing properties. However, there are primary cell walls on the surface of natural cotton fibers, and the cotton wax in the primary cell walls is the source of cotton's hydrophobicity; in addition to cotton wax, other insoluble salts belonging to pectin also promote unscoured cotton fibers. of hydrophobicity. The cotton fibers after traditional dyeing and finishing process also greatly reduce the hygroscopicity of cotton because they contain more hydrophobic oil agents, so the hydrophilicity ...
