AI Technical Summary

Benefits of technology

This patented technology allows creation of pure protein from animal hides while minimizing wastewater disposal issues. By selecting an appropriate type of proteolue called histidase, which breaks down fibrous materials like spun threads or woolen yarn bundles, they become soluble into liquids instead of being absorbed onto other parts of their body. These processes help reduce pollution and improve nutritional value. Additionally, these techniques allow for efficient degradations of carbohydrate-rich substances such as celluloskeleton polysaccharide (CSP) gums found naturally within food crops.

Problems solved by technology

Technics described for this patented problem involve various factors including environmental concerns associated with producing or purifying silks from spiders' wax sheaths during manufacturing processes like extracting fibers from them through cleanings made using different methods (scours) followed by solvent extraction techniques. These technical effects include improved energy utilization, reduced emissions caused by burning fossil fuels, increased production rates without requiring excessive maintenance work, efficient management of residues produced after the preparation steps, prevention against contaminants entering the factory, reduction of human exposure to harmful substances, and minimizing damage to equipment involved when manually removing covers worn down by users.

Embodiment 1

[0023] A biological enzyme degumming method for tussah silkworm cocoon shells, said tussah silkworm cocoon shell biological enzyme degumming method consists of the following process steps:

[0024] 1) Add 1000kg of clean water to the degumming tank;

[0025] 2) Heat the water in the degumming tank to 45-50°C;

[0026] 3) Put soda ash into the degumming tank, and stir evenly, so that the pH value of the water in the cocoon cooking tank reaches 9.0;

[0027] 4) Put 0.8 kg of 2709 alkaline protease into the degumming tank to obtain the degumming solution;

[0028] 5) Put 40kg of cocoon shells into the degumming tank, immerse the cocoon shells in the degumming solution, and keep stirring, keep the temperature of the degumming solution at 45-50°C, soak for 4 hours;

[0029] 6) When the residual glue rate of silk is less than or equal to 3%, fish out the silk and the degumming is over.

Abstract

The invention discloses a tussah cocoon shell bio-enzyme degumming method which is composed of the steps that: clear water is added into a degumming tank body; the clear water in the degumming tank body is heated to 45-50 DEG C; soda ash is added into the degumming tank body, and the mixture is well mixed, such that the pH value of the water in a cocoon boiling tank reaches 9.0; 2709 alkaline protease is added into the degumming tank body, such that a degumming liquid is obtained; cocoon shells are added into the degumming tank body, and are completely immersed in the degumming liquid; the mixture is continuously stirred, and degumming temperature is maintained at 45-50 DEG C; soaking is carried out for 3-4h; when silk residual gum is lower than or equal to 3%, the silk is fetched, and degumming is finished. When cocoon shells are subjected to a degumming process by using the tussah cocoon shell bio-enzyme degumming method, production cost is low, degummed silk quality is good, and sericin in the degumming liquid can be recovered.
