Production method for degrading cocoa shell into polysaccharide for grafting onto polymer and yarn thereof

A production method for degrading cocoa shell into polysaccharide for grafting onto polymer, comprising:

• (1) preparing anaerobic thermophilic lignin-decomposing bacteria;
• (2) preparing a cocoa shell powder of cocoa shell;
• (3) preparing a cocoa shell degradation aqueous solution:
• adding the cocoa shell powder into a decomposing bacteria culture solution with the anaerobic thermophilic lignin-decomposing bacteria, wherein during a course of preparation, the pH value of the decomposing bacteria culture solution is set to be between 4-8 and after a preset time, the anaerobic thermophilic lignin-decomposing bacteria degrade the cocoa shell powder to obtain a cocoa shell degradation aqueous solution;
• and
• (4) polymerizing the cocoa shell degradation aqueous solution into polysaccharide and performing grafting processing:
• subjecting the cocoa shell degradation aqueous solution to a centrifugation process to obtain a degraded saccharide liquid and setting a saccharide content of the saccharide liquid to be between 70%-80%, and adding sorbitol and citric acid to carry out high temperature melting for polymerization to obtain a polysaccharide powder;
• placing the polysaccharide powder and N-isopropylacrylamide (NIPAAm) in a reaction vessel filled with ethanol and added with an initiator to carry out a preset reaction process and carrying out a drying process after the reaction process is completed to obtain a polysaccharide-grafted N-isopropylacrylamide (NIPAAm) powder;
• and finally, subjecting the polysaccharide-grafted N-isopropylacrylamide (NIPAAm) powder to a blending process with a polymer to allow the polysaccharide-grafted N-isopropylacrylamide (NIPAAm) powder to covalently bond to the polymer to complete a polysaccharide-grafted N-isopropylacrylamide (NIPAAm) blended polymer.
