Embodiment 1

[0041] (1) Cashmere selection and cashmere opening: select cashmere fibers of about 16 μm, open the selected cashmere with a cashmere turbine, and open the cashmere through multiple light beating turbines.

[0042] (2) Enzyme treatment and washing:

[0043] Both papain and bromelain are food grade, with an activity of 500,000 u / g.

[0044] The first pass: 1% papain + 1% sodium bisulfite aqueous solution, the water temperature is kept at 50°C; the pH is controlled at 7, and the treatment time is 15 minutes;

[0045] The second time: 1.5% bromelain solution, the water temperature was kept at 55°C; the pH was controlled at 7, and the treatment time was 15 minutes;

[0046] After enzyme treatment, rinse with clean water and keep the temperature at 55°C;

[0047] Enzyme-treated cashmere removes all kinds of dirt and is chemically altered;

Abstract

The invention discloses a preparation method of high-elongation skin-friendly cashmere yarn. Basically no chemical agents are added in the whole processing process of the high-elongation skin-friendly cashmere yarn. Biological enzymes especially papain and bromelain are fully utilized in the process. Operation is easy, and the optimal parameters of the technique are verified through a large number of experiments. Compared with indexes of cashmere yarn in the prior art, multiple indexes of the prepared cashmere yarn are greatly improved, and especially the advantages of the high elongation and the skin-friendly effect are achieved.

Description

technical field [0001] The invention belongs to the technical field of knitting yarn and its production process, and in particular relates to a high-elongation skin-friendly cashmere yarn and its production process. Background technique [0002] Cashmere is known as "diamond fiber" in the wool spinning industry. It is a special fiber with the characteristics of lightness, softness, bath and waxiness. Cashmere fabric is soft and smooth, comfortable and warm to wear, smooth and delicate to the touch, elegant and luxurious in vision, soft and bright in luster. Cashmere fibers are thin and short in length, usually with an average fineness of 13-16 μm and an average length of 30-60 mm. The strength of single fibers is not high, and the average strength of single fibers is 3.0-4.5 CN. Therefore, in the process of processing and production, reducing fiber damage is very important to improving the quality of yarn. There has always been a prominent problem in cashmere knitted prod...
