Problems solved by technology

[0008] 4. Protease: Use sodium carbonate to adjust the PH value to about 8.5, add Novozymes’ Novozyme-16 protease, which has poor directionality, and the PH value is about 8.5. Treat it at 45-50°C for 30-40 minutes. Because wool is not resistant to alkali, it will cause great damage to wool and reduce the elasticity and bulkiness
[0013] The weight loss of the wool yarn treated by this process is 4-6%, the strength is reduced by about 15%, and the superfine fiber is about 10%.

Embodiment 1

[0061] As shown in Figure 1, the production process of the machine washable Silk fleece of the present invention, the technological process is as follows:

[0062] (1) Washing line:

[0063] Use 64 S The yarn count spun from the above wool is 16 s 100 kilograms of raw wool yarn is put into the dyeing vat of Y600 open-door wool dyeing machine. The capacity of Y600 is 200 kilograms, and the optimum processing capacity is 120 kilograms of wool yarn. Add water to the water level, add 2 kilograms of non-ionic lotion 105 for washing, and control the temperature at 40°C, wash the thread for 15 minutes, then rinse, lighten the water, and control the oil content below 0.5%;

[0064] (2) Pretreatment:

[0065] Use additives to reduce the surface tension of wool, so that sodium dichloroisocyanurate, etc. can easily enter the scale layer, the outer layer of cutin, and the cortex to the intercellular substance. In addition, use acylated phthalein and its derivative wool protectant to ma...

Embodiment 2

[0095] 1) Washing line:

[0096] Use 70 S The yarn count spun from wool is 26 s Put 100 kg of yarn into the dyeing vat of Y600 open-door wool dyeing machine. The capacity of Y600 is 200 kg, and the optimal processing capacity is 120 kg. Water is added to the water level, and non-ionic lotion JU is added for washing. The dosage is equivalent to that of wool yarn The percentage of billet weight is 4.5%, the temperature is controlled at 48-50°C, the thread is washed for 15-20 minutes, then rinsed, the water is lighted, and the oil content is controlled below 0.5%;

[0097] (2) Pretreatment:

[0098] Soak the washed woolen yarn to the water level, add 4 kilograms of penetrating agent JFC and 14 kilograms of acylated phthalein derivative colloid protective agent respectively in water (this derivative is that the second carbon position in the acylated phthalein structure increases a hydroxyl group, Add a hydroxyl amino group to its ortho position), then adjust the pH value to wea...

Embodiment 3

[0126] (1) Washing line:

[0127] Use 80 S Wool spun yarn count 32 s Put 60 kg of raw yarn yarn into the dyeing vat of Y300 open-door wool dyeing machine. The capacity of Y300 is 100 kg. Add water to the water level, add 1.2 kg of non-ionic lotion 105 for washing, and control the temperature at 65-70 °C. 12 minutes, then rinse, lighten the water, and control the oil content below 0.5%;

[0128] (2) Pretreatment:

[0129] Soak the washed woolen yarn to the water level, add 0.9 kg of penetrant JFC and 4.8 kg of colloidal protective agent acylated phthalein to the water, then adjust the pH value to weak acidity with glacial acetic acid, control the water temperature at 25°C to 30°C, and treat for 35 ~40 minutes;

[0130] (3) Weightlessness treatment:

[0131] Then add 10 kilograms of sodium dichloroisocyanurate with a total weight of 4 times in the dye vat, and its molecular formula is C 3 Cl 2 N 3 o 3 Na, the reaction temperature is 20-25°C, measure the end point with p...

Abstract

This invention provide a snow floss and produce technics .The produce anti pilling is strong, still have excellent elasticity, droop capability, the trait of washed by machine. Especially the little ball rises after wear can be opened automatically after washed by machine and floss sense become better. This snow floss have trait: a, compare with common gauze of the same branch and slender, resist teaseling is better one level; b, compare with common gauze of the same branch and slender, flexibility is better about 20-80% and mightiness descend 15-20%; c, compare with former gauze fell branch heighten 3-15%, weightlessness about 10-40%,gauze branch boost 10-20; d, after washed by machine and washed by hand, the little ball can open automatically; e, after slopwork, the area minification is in 1.5-5%; f, in naturally state, the chubbiness is 115%-170% about former gauze. The technics process is: wash line - pretreatment- weightlessness manage-escaping from chlorine-enzyme manage -flush-coloration former manage-back settle -dehydrate and drying.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a wool yarn processing technology and product. Background technique [0002] International superfine wool is seriously in short supply, but it is not as good as cashmere in terms of fineness and cashmere, and the raw material of cashmere comes from goats, which eat up all the grass roots, desertifying the grassland and seriously affecting the ecological balance. In addition, cashmere products have poor elasticity. , Pilling, poor sagging and other problems, most of its cashmere products cannot be machine washed, and will be deformed during manual washing, which is time-consuming and labor-intensive. Moreover, the price of cashmere is much higher than that of wool products. How to fine-process wool products to increase their added value so that they can surpass cashmere products under the conditions of excellent performance and low cost has become a research direction for insider...
