Embodiment 1

[0026] Sample species: full wool gabardine.

[0027] Technological process: Padding compound enzyme solution of all-wool gabardine after boiling→steaming and heat preservation stacking→hot water washing (and enzyme elimination)→full washing in cold water→drying.

[0028] Among them, the composition of the compound biological enzyme treatment solution is: cutinase 5.5g / L, keratinase 6g / L, protease 2g / L, wetting and penetrating agent 2g / L, padding solution pH8.5. Padding composite biological enzyme treatment solution, the temperature of the enzyme treatment solution is 50°C, and the fabric scrapping rate is 120%. The steaming temperature is 55°C, and the steaming time is 90 minutes. After treatment, treat in hot water at 95-100°C for 5 minutes to inactivate enzymes, then wash thoroughly in cold water and dry.

[0029] The wool gabardine treated by the above process has a weight reduction rate of 3.9%, a wetting time of 80s, a fabric surface felt shrinkage rate of 5.6%, and a f...

Embodiment 2

[0031] Sample species: all wool veritin.

[0032] Technological process: padding compound enzyme solution of boiled all-wool veritin fabric→steaming and heat preservation stacking→hot water washing (and enzyme elimination)→full washing in cold water→drying.

[0033] Among them, the composition of the compound biological enzyme treatment solution is: 9 g / L of keratinase, 3 g / L of protease, 2 g / L of wetting and penetrating agent, and the pH of the padding solution is 8.0. Padding composite biological enzyme treatment solution, the temperature of the enzyme treatment solution is 45°C, and the fabric scrapping rate is 100%. The steaming temperature is 55°C, and the steaming time is 120 minutes. After treatment, treat in hot water at 95-100°C for 5 minutes to inactivate enzymes, then wash thoroughly in cold water and dry.

[0034] After the above process, the weight reduction rate of the all-wool veneer fabric is 2.9%, the wetting time is 150s, the felt shrinkage rate of the fabr...

Abstract

The invention discloses a pure-wool worsted fabric compound bio-enzyme padding-steaming stacking anti-felting finishing technology, belonging to the technical field of wool fabric dyeing and finishing in the wool spinning industry. A continuous padding-steaming stacking method adopted by the invention comprises the following steps of: padding the pure-wool worsted fabric in a compound bio-enzyme solution consisting of different combinations of cutinase, keratinase and protease; performing steaming stacking at certain temperature for certain time; performing hot water washing (as well as enzyme deactivation); sufficiently washing with cold water to remove various enzyme decomposition products, deactivated enzyme and impurities on the wool fabric; and finally drying. Through the technology disclosed by the invention, the acting efficiency of the keratinase and protease and the anti-felting effect of the wool fabric can be obviously improved; and the technology also has the advantages of obvious reduction in water consumption, obvious reduction in wastewater discharge, obvious improvement of production efficiency and the like.

Description

technical field [0001] The invention relates to an all-wool worsted fabric compound biological enzyme padding-steaming stacking 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 fluffing properties. Wool fabrics will shrink when subjected to external forces in a humid and hot state, which will cause the area of ​​the fabric to shrink, the shape will change, the fluff will protrude, the elasticity will decrease, the hand will be rough, and the appearance and wearing performance of the fabric will be seriously affected. Therefore, it is necessary to perform anti-felting finishing on wool fabrics. The methods of anti-felting finishing of wool fabrics mainly include weight reduction anti-felting finishing for the main purpose of removing scales and additive anti-felting finishing of coating polyurethane or silicone polymer resin on the wo...
