Embodiment 1

[0020] An enzyme-catalyzed grafting functional finishing method for wool:

[0021] The wool item is all-wool gabardine: the finished product has a width of 145cm, a square meter weight of 317 grams, 438 warp density / 10cm, and weft density 253 / 10cm.

[0022] Process flow: Treat wool goods in a pH buffer solution for a certain period of time, add transglutaminase and functional primary amine, treat them at a certain temperature for a certain period of time, terminate the reaction, wash with water, and dry.

[0023] among them,

[0024] 1) Pretreatment: The wool fabric is immersed in a buffer solution of pH=8.5 for 60 minutes, and the bath ratio is 1:20. In the treatment bath, 1% polyoxyethylene type nonionic surfactant is added as a wetting and penetrating agent. The buffer is a solution formed by mixing 28.1 mL of 0.2mol / L tris (Tris) solution and 16.8 mL of 0.1N HCl solution;

[0025] 2) Enzyme catalytic function finishing: add 10% (to the wool weight) transglutaminase and a funct...

Embodiment 3

[0038] Example 3: An enzymatic grafting functional finishing method for wool:

[0039] The wool item is all-wool gabardine: the finished product has a width of 145cm, a square meter weight of 317 grams, 438 warp density / 10cm, and weft density 253 / 10cm.

[0040] Process flow: pretreat the wool with hydrogen peroxide and protease, then treat it in transglutaminase and functional primary amine at a certain temperature for a certain period of time, terminate the reaction, wash and dry.

[0041] among them,

[0042] 5) Pretreatment process:

[0043] Hydrogen peroxide pretreatment: H 2 O 2 40mL / L, penetrant JFC1g / L, water glass 1g / L, temperature 50℃, bath ratio 1:20, treatment for 1h. Wash thoroughly.

[0044] Protease pretreatment: the amount of protease is 1% relative to the weight of the wool article, the treatment time is 40 minutes, and the treatment temperature is 50°C. After the enzyme protein treatment, kill the enzyme with hot water at 80°C for 10 minutes, and wash with water. ...

Abstract

The invention discloses an enzyme catalysis graft function finishing method of wool, comprising the steps of pretreatment, enzyme catalysis graft function finishing, hot water termination reaction, water-washing for 10 times, then drying at the temperature of 60 to 80 DEG C and the like. The method adopts transglutaminase catalytic functional primary amine to graft and finish the wool, thus improving the performances of antiflaming, antibiosis, uvioresistance, skin-friendly and easy nursing and the like of the wool. The additional value of the wool is added; and the enzyme catalysis function finishing method has good durability, is environment friendly, and has strong operability, lower processing temperature, and no influence to the whiteness and other performances of the wool, thus being an energy-saving, environment-friendly and clean wool after-finishing technology.

Description

Technical field: [0001] The invention relates to a method for carrying out durable functional finishing of wool, which is a finishing technology for textile functional finishing and wool dyeing and finishing industries. Background technique: [0002] Wool fabric has a unique appearance style and excellent warmth retention function, and has the characteristics of soft hand feeling, bright color, plump suede, light and comfortable wearing, etc., and is well received by consumers at home and abroad. With the improvement of people's quality of life and consumer demand, the demand for comfort, easy care, safety, and health care functions is increasing. In order to adapt to changes in market demand, it is necessary to realize a revolution in product functions and develop functional woolen products. [0003] In order to improve the durability of wool functional finishing, chemical cross-linking agents and high-temperature baking methods are generally required. Chemical cross-linking age...
