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;

Abstract

The invention discloses a preparation method of a machine-washable cashmere sweater. A chemical reagent is basically not added in the whole machining process, so that the method is natural and environmentally friendly and belongs to green processes. Biological enzymes, in particular papain and bromelain, are fully utilized in the process, and the operation is simple. The machine-washable cashmere sweater provided by the invention is very excellent in index performance, high in bursting strength, washable and resistant to abrasion and pilling, and cannot become deformed by machine washing.

Description

technical field [0001] The invention relates to a preparation method of a cashmere sweater, in particular to a processing technology of an environment-friendly cashmere sweater which is anti-pilling and machine washable without adding any chemical reagents in the whole processing 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...
