Benefits of technology

This patented technology improves the efficiency of removing unwanted materials from fibers without causing them to lose their shape permanently due to heating during processing. By treating it with specific substances like chemistry or proteolysis, these processes can help prevent shedding particles onto other parts of the process stream while also reducing harmful emissions into the atmosphere through evaporation. Additionally, this new technique allows for controlled deposition of various types of molecular material (biomacrins) onto the fibers' surfaces instead of just adding any type of compound directly to the manufacturing process itself. Overall, this innovation enhance the performance and durability of wools used in industry such as clothing production.

Problems solved by technology

This patented technical problem addressed in this patent relates to developing a better way to protect wools without causing harm or reducing their quality during processing. One approach involves modifying them through various methods such as adding water soluble salts like calcium sulfite or sodium bichromolorethanolate into the fabric' s surface before dry cleaning. These modifications help prevent shedding off particles when wet but they can also cause unwanted side effects if applied too much overall.

Embodiment 1

[0014] Wool fabrics were oxidized with potassium permanganate (KMnO 4 : 4% (o.w.f), JFC 1g / L, pH=3-5, T=40°C, t=30min, bath ratio 1:20), fully washed and dried, then immersed in protein 3g / L, enzyme dosage It is a solution of 10-20U / g wool, the bath ratio is 1:20, the reaction temperature is 35°C, the pH is 6.5, and the reaction time is 1 hour. After the reaction, the fabric was fully washed and dried at 50°C.

[0015] The shrinkage rate of the fabric after the above treatment is 1.87%, and the strength is 435N. The COD value of the treatment solution is 31000mg / L. Compared with the original fabric felt shrinkage rate of 9.5%, the felt shrinkage rate is reduced.

Embodiment 2

[0017] After the wool fabric was treated with protease Savinase 16L (enzyme: 1g / L, JFC 1g / L, pH=8, T=50°C, t=45min, bath ratio 1:20), it was fully washed with water and dried, and then soaked in / L, the enzyme dosage is 10-20U / g wool solution, the bath ratio is 1:20, the reaction temperature is 35°C, the pH is 7.5, and the reaction time is 3 hours. After the reaction, the fabric was fully washed and dried at 50°C.

[0018] The shrinkage rate of the fabric after the above treatment is 3.27%, and the strength is 456N. The COD value of the treatment solution is 27000mg / L. Compared with the original fabric felt shrinkage rate of 9.5%, the felt shrinkage rate is reduced.

Abstract

The invention discloses a method that is used for finishing wool fabrics by catalyzing a foreign protein through a transglutaminase and belongs to the filed of biotechnological application. The method implements proper chemical or protease preprocessing on wools, grafts and coats a gelatinum of the foreign protein or a caseinum on the surface of wool fibers under the catalysis of the transglutaminase, endues the wool fabrics with certain felt-proof property, and improves the physical and mechanical performance of the wool fabrics to a certain degree. Compared with the traditional felt-proof finishing methods of the wools, the method that is used for finishing the wool fabrics by catalyzing the foreign protein through the transglutaminase replaces traditional chemical finishing agents with bio-enzyme and biomacromolecule, has less fiber strength loss and is easier to control by comparing with pure protease processing, leads the biological modification of the wools to be possible, greatly lowers environmental pollution, reduces COD in discharged water and improves ecological environment; simultaneously the method has gentle action condition, avoids high-temperature baking, saves energy and improves the quality of fabric products.
