The invention discloses a method for improving the refining effect of fabrics before printing and dyeing by a biological enzyme method. Through bioinformatics analysis, members of the AA9 family of cleavage polysaccharide monooxygenases were mined from public databases to obtain the sequences of cleavage polysaccharide monooxygenases with cellulase activity, and their protein expression and enzyme activity characterization found that they can be highly efficient Synergistic cellulase to decompose cellulose substrate, applying this lytic polysaccharide monooxygenase and H 2 O 2 to the desizing refining process before textile printing and dyeing, it is found that it can cooperate with cellulase to improve the refining effect , to improve the wool effect and softness of the fabric. |
