Method for using glutamine aminotransferase catalyzing exogenous protein to clean wool fabric

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.

AI Technical Summary

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.
