b. Enzyme treatment: treating with 1% sodium bisulfite and 1% papain in water at 50 deg.C and pH 7 for 20min, and treating with 1.5% bromelain at 55 deg.C and pH 7 for 10 min;
c. Cleaning: rinsing with clean water at 55 ℃;
d. And (3) drying the velvet: drying the cashmere by using drying equipment;
e. Carding: spraying clear water into the raw materials, and fully stewing and standing the cashmere;
f. And velvet: adding soybean oil and water into the carded cashmere for cashmere treatment;
g. Carding: carding the cashmere after the cashmere is blended by a cashmere carding machine;
h. And (3) pile forming: spinning the spun yarn by a spinning frame;
i. Weaving: placing the spun yarn into weaving equipment to weave into a cashmere sweater;
j. Dyeing: dyeing and drying the knitted cashmere sweater by using a dyeing machine;
k. Anti-felting treatment: treating cashmere sweater in 90 deg.C hot water, adding bromelain at 55 deg.C to obtain water solution, treating for 1 hr, inactivating enzyme in 90 deg.C hot water, cleaning, and air drying to obtain machine washable cashmere sweater;
according to the invention, enzyme treatment is carried out on cashmere by papain, so that the mechanical property of a subsequent cashmere sweater is less damaged, the cashmere sweater can be protected from being damaged by low-temperature heating, the size stability of the sweater can be ensured to reach the standard by setting the combined cashmere to have a count of 26NM and setting a twist coefficient of 90% in a flexible carding mode with light ration, small spacing, small drafting and carding angles, compared with the conventional twist of 85%, the size stability of the sweater can be ensured to reach the standard by weaving a character code which is slightly tighter than the normal, and the standard of machine washing can be easily reached.
The papain in the step b is natural protease extracted from milk in immature papaya fruits. The polypeptide has wider substrate specificity, acts on peptide bonds formed by participation of L-arginine, L-lysine, glycine and L-citrulline residue carboxyl in protein, can cut off peptide chains-CO-NH-in whole protein molecules to generate polypeptides with smaller molecular weight, and when the polypeptide is used for preventing cashmere shrink, the hydrolysis speed of scale surface protein is equal to or similar to that of spherical protein, so that the hydrolysis mode effect of uniform treatment is achieved, and the hydrolysis mode concentrates the action of protease on the surface of cashmere, so that the heart rot phenomenon does not exist, and the mechanical property of the cashmere is less damaged.
The bromelain in the step b is a pure natural plant protease which is obtained by extracting stems, leaves and peels of pineapple fruits, refining, purifying, concentrating, immobilizing enzyme and freeze-drying. The cashmere after enzyme treatment can remove various dirt and change chemical properties.
