Embodiment 1
[0043] (1) Cashmere selection and cashmere opening: select 16.0um cashmere fibers with a length of 35-38mm, use the cashmere turbine to open the selected cashmere, and open the cashmere through multiple light beating turbines.
[0044] (2) Enzyme treatment and washing:
[0045] Both papain and bromelain are food grade with an activity of 500,000 u / g.
[0046] The first pass: 1% papain + 1% sodium bisulfite aqueous solution, the water temperature is kept at 55°C; the pH is controlled at 7, and the treatment time is 20 minutes;
[0047] The second pass: 1.5% bromelain, the water temperature is kept at 50°C; the pH is controlled at 7, and the treatment time is 10 minutes;
[0048]After enzyme treatment, rinse with clean water and keep the temperature at 55°C;
[0049] Enzyme-treated cashmere removes all kinds of dirt and is chemically altered;
[0050] (3) low temperature dyeing:
[0051] The wool is dyed with reactive dyes, the dyeing temperature is controlled at 70°C, and t...
