Embodiment 1

[0027] Specimen variety: full wool serge fabric, 350g / m 2 .

[0028] Process flow: After cooking, the whole wool serge fabric is impregnated with a complex enzyme solution at room temperature, rolled at room temperature (25°C), slowly rotated and stacked at 20rpm for 8 hours, washed with hot water at 90°C (to kill enzymes), Wash thoroughly with cold water and dry.

[0029] Among them, the composition of the composite biological enzyme treatment solution is: cutinase 8.5 g / L, keratinase 15 g / L, protease 3 g / L, wetting and penetrating agent 2 g / L, urea 15 g / L, and treatment bath pH 8.0. The compound bio-enzyme treatment liquid is padding, the temperature of the enzyme treatment liquid is 25°C, and the fabric rolling rate is 110%. Stacked at 25°C for 8h. After treatment, it is treated in hot water at 95-100°C for 5 minutes to inactivate the enzyme, and then fully washed with cold water and dried.

[0030] The full wool serge treated by the above process has a weight loss rate of 2.9%...

Embodiment 2

[0032] Specimen variety: All wool Fanlitin.

[0033] Technological process: After cooking, the whole wool vanidin is soaked in the compound enzyme solution at room temperature, rolled at room temperature (30°C), slowly rotated and stacked at 18 rpm for 6 hours, washed with hot water (to kill enzymes), and washed fully with cold water ,drying.

[0034] Among them, the composition of the composite biological enzyme treatment solution is: cutinase 6.0 g / L, keratinase 12 g / L, protease 2.5 g / L, wetting penetrant 2 g / L, and the treatment bath pH 7.5. The compound bio-enzyme treatment solution is padding at room temperature, and the fabric squeezing rate is 120%. Stacked at 30°C for 6h. After treatment, it is treated in hot water at 95-100°C for 5 minutes to inactivate the enzyme, and then fully washed with cold water and dried.

[0035] After the above-mentioned process, the weight reduction rate of all-wool vanidin is 3.6%, the wetting time is 120s, the fabric surface felt shrinkage ra...

Abstract

The invention discloses a wool fabric complex phosphoesterasum padding-room temperature rolling yarding anti-felting tidying craft, and belongs to the technical field of dyeing, finishing and processing wool fabric. A full width and semi continuous padding-room temperature rolling yarding method is adopted. Full wool exquisite textile fabric is padded in composite biological enzyme liquid composed of cutinase, keratinase, protease and wool sweller urea. The full wool exquisite textile fabric is rolled up for certain time under the room temperature, and then is washed by hot water ( combined with enzyme deactivation treatment), and is fully washed by cold water to eliminate various enzyme decomposition products, inactivated enzyme and impurities on the wool textile fabric, and is dried at last. According to the wool fabric complex phosphoesterasum padding-room temperature rolling yarding anti-felting tidying craft, working efficiency of the keratinase and the protease and anti-felting effect of the wool textile fabric can be remarkably improved. Surface smoothness of the fabric is improved, and wearability of the fabric is improved. And the semi continuous method of room temperature rolling yarding is adopted, and therefore the water consumption is remarkably reduced, waste water discharge is obviously reduced, production efficiency is remarkably improved, and steam is saved and the like.

Description

Technical field [0001] The invention relates to a wool fabric composite enzyme padding-room temperature rolling stacking method (cold padding method) anti-felting finishing process, which belongs to the application technical field of wool fabric dyeing and finishing in the wool textile industry. Background technique [0002] Wool has felting properties. When the wool fabric is subjected to external force in the state of heat and humidity, it will shrink, which will shrink the area of ​​the fabric, change the shape, highlight the fluff, reduce the elasticity, feel rough, and seriously affect the appearance and wearability of the fabric. Therefore, The wool fabric needs to be finished with anti-felting. The anti-felting finishing methods of wool fabrics mainly include two types of anti-felting finishing with the main purpose of removing the scale layer and the additive anti-felt finishing of coating the surface of the wool fiber with polyurethane or silicone polymer resin. At pres...
