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 at 55 °C After 20 minutes, add 8 g / L caustic soda and raise the temperature to 90°C. After soaking 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 pH to 5.5 with HAC, bath ratio 1:8, immerse at 60°C for 30 minutes, dehydrate directly, 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 kg of cotton loose fiber, put it into a solution with a bath ratio of 1:15 and containing 1 g / L of chelating dispersant WA (soft water effect), scouring enzyme 301L 1%, cellulase L, penetrant JFC at room temperature 1%, adjust the pH to 4.8 with HAC, add 10 g / L caustic soda and 8 g / L hydrogen peroxide after treating at 50°C for 30 minutes, after soaking 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, immerse 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 kg of cotton sliver loose fiber, put it into a solution with a bath ratio of 1:10 and 2 g / L of chelating dispersant CT powder (soft water effect) at room temperature, scouring enzyme 301L 1%, cellulase L penetrating agent JFC 1%, adjusted the pH to 4.8 with HAC, treated at 50°C for 40 minutes, then added 10 g / L caustic soda at 80°C, soaked for 40 minutes, neutralized with acetic acid and washed 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, liquor ratio 1:10, soak for 30 minutes at 50°C, directly dehydrate 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.
