Problems solved by technology

The invention can improve the wettability of wool fibers and the effect of biological enzyme anti-felting finishing of wool products, solve the technical problems of large fiber damage and serious environmental pollution in traditional chlorination wool anti-felting finishing, achieve optimal treatment effect, improve environment, the purpose of improving the quality of wool products; at the same time, because the present invention adopts the two-bath finishing process in which wool products are first treated in a compound enzyme solution composed of cutinase and keratinase, and then treated in a protease solution, it can avoid cutin Enzyme, keratinase and protease are treated with different optimal conditions in one bath method, which affects the efficiency of their respective enzymes, and protease may affect the decomposition of cutinase or keratinase, which is also composed of protein, and affect cutinase and keratinase. The enzymatic activity and effect of protease can significantly improve the efficiency of subsequent protease treatment

Embodiment 1

[0029] Sample species: wool fiber.

[0030] (1) Immersion in a composite enzyme solution composed of cutinase and keratinase: the wool fiber is soaked in a wetting and penetrating agent solution containing 2.5% cutinase, 2% keratinase and 2g / L in mass concentration, Temperature 55°C, pH 7.0, time 1.5 hours.

[0031] (2) The treated fibers are first washed with cold water for 5-10 minutes, and then washed with hot water at 50-70°C for 10 minutes to fully clean various impurities on the fibers;

[0032] (3) Immersion in protease solution: soak the above-mentioned washed wool fiber in a solution containing protease with a mass concentration of 1.0% and a wetting and penetrating agent of 2 g / L at a temperature of 50° C., pH 8.0, and time of 50 min;

[0033] (4) Enzyme inactivation: After the treatment, raise the temperature of the enzyme solution to 80-90°C for 10 minutes to inactivate the above-mentioned enzymes;

[0034] (5) Water washing: the wool fiber after the enzyme is el...

Embodiment 2

[0037] Sample species: wool strips

[0038] (1) Soaking in a composite enzyme solution composed of cutinase and keratinase: soaking the wool strip in the wetting and penetrating agent solution containing 3.5% cutinase, 2.5% keratinase and 2g / L of mass concentration, Temperature 55°C, pH 7.0, time 1.0 hour;

[0039] (2) Wash the treated wool strips with cold water for 5-10 minutes, and then wash them with hot water at 50-70°C for 10 minutes to fully clean all kinds of impurities on the wool strips;

[0040] (3) Soaking in protease solution: soak the above-mentioned washed wool strips in a solution containing 2.0% protease and 2g / L wetting and penetrating agent at a temperature of 50°C and a pH of 8.0 for 60 minutes;

[0041] (4) Enzyme inactivation: After the treatment, raise the temperature of the enzyme solution to 80-90°C for 10 minutes to inactivate the above-mentioned enzymes;

[0042] (5) Water washing: the wool sliver after the enzyme has been deactivated is fully wash...

Abstract

The invention discloses a wool product two-bath process anti-felting treatment technology based on composite bio-enzyme, belonging to the technical field of wool fabric dyeing and finishing, which is aimed at solving the shortcomings that a wool chlorination anti-felting method causes serious environmental pollution, a single protease method has low wettability and high felting rate in treating fabric, a cutinase, keratinase and protease three-step method has low treatment efficiency, a cutinase, keratinase and protease one-step method requires inconsistent optimal action conditions in treating the three enzymes and the protease possibly decomposes the rest two enzymes in a one-bath method so as to realize an effect of optimizing wool fabric protease treatment. A wool sample is pretreated in a solution containing certain concentration of cutinase and keratinase to remove hydrophobic lipoids on the surface of wool and decompose the dense structure of wool scales; then, the wool sample is treated in the protease solution; and through the synergistic effect of the three-enzyme two-bath method, the acting efficiency of the protease is improved. The technology disclosed by the invention can replace the traditional chlorination anti-felting method, and improve the anti-felting performance of a wool product.

Description

technical field [0001] The invention discloses a two-bath anti-felting finishing process for wool products based on a compound biological enzyme, 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 wool fiber surface. At...
