| titleOfInvention | Real silk antibacterial finishing method based on enzymatic conversion and grafting |
| abstract | The invention discloses a real silk antibacterial finishing method based on enzymatic conversion and grafting, which is characterized in that glycine in protein fiber macromolecules is catalyzed by serine hydroxymethyltransferase to be converted into serine, the number of the serine in real silk fibers is increased, the serine in the real silk fibers is catalyzed and oxidized by laccase and a 2,2,6, 6-tetramethylpiperidine-nitrogen-oxide (TEMPO) system to generate aldehyde groups, and the aldehyde groups are crosslinked with polylysine to carry out real silk antibacterial finishing. The method specifically comprises the following steps: (1) enzymatic conversion of amino acids in real silk; (2) and (3) catalytically oxidizing real silk grafted polylysine by laccase-TEMPO. Compared with the traditional chemical crosslinking antibacterial finishing method, the real silk treated by the method has good antibacterial performance, mild enzyme treatment conditions and improved physical and mechanical properties compared with the untreated real silk. |
