Description
Technical Field
The invention belongs to the technical field of textile, and particularly relates to a processing technology and a product of wool yarns.
Background
The international superfine wool is not suitable for supply, but is not like cashmere in the aspects of fineness, cashmere degree and the like, the raw material of the cashmere comes from goats, and the goat with grass roots is draughty, so that grasslands are desertified, the ecological balance is severely affected, in addition, the cashmere products have the problems of poor elasticity, poor pilling performance, poor drooping performance and the like, most cashmere products cannot be washed by machines, and can deform during manual washing, thereby being time-consuming and labor-consuming. Besides, the price of cashmere is very high compared with that of a wool product, how to finish the wool product and improve the added value of the wool product is better than that of the cashmere product under the conditions of excellent performance and low cost, and the cashmere finishing method becomes the research direction of the people in the prior art.
The mercerization prevention and ecological velvet treatment process and the achieved effects are introduced by combining the prior processing process and products as follows:

3. dechlorination: treating with 5% sodium pyrosulfite or sodium sulfite at 40 deg.C for 30 min, washing with clear water (or washing for 5 min), and adding water;
4. protease: adding 2% penetrating agent JFC, operating at 40-45 deg.C for 10 min, adjusting pH to about 8.5 with 0.15-0.25% Denmark Novoxin and-16 protease, treating at 45-50 deg.C for 30-40 min, and discharging clear and bright; (or the water is discharged after 5 minutes of flushing), and the water is fed again, flushed and discharged;
5. neutralizing: neutralizing with glacial acetic acid at room temperature for 15 min, washing,and polishing; if necessary, treating the mixture by using 1 percent peregal O at the temperature of 45 ℃ for 15 to 30 minutes, flushing and discharging light water;
