Problems solved by technology

However, cellulase preparations also have a problem that cannot be ignored: the washed indigo dye will re-contaminate the denim clothing, resulting in varying degrees of staining on the reverse side of the denim clothing and its white pocket cloth, reducing the whiteness. Contrast between weft yarns and indigo-dyed blue warp yarns affects the appearance of denim garments, thereby reducing their added value

Abstract

The invention relates to the technical field of biological enzyme preparations and textile aids, and discloses an anti-staining stabilizing additive composition, a preparation method and applicationsthereof, and a compounding cellulase and applications thereof, wherein the anti-staining stabilizing additive composition contains 5-50 wt% of fatty alcohol polyoxyethylene ether, 1-20 wt% of polyethylene glycol, 1-30 wt% of an aqueous polyester, 2-20 wt% of sorbitol, 1-10 wt% of a saccharide substance, 0-10 wt% of polyvinylpyrrolidone, 0.05-2 wt% of a preservative, and the balance of deionized water. According to the present invention, the compounding cellulase contains the anti-staining stabilizing additive composition, has good stability, and can prevent Denim clothing from color staining to different degrees, color contamination and other phenomena during industrial water washing so as to improve the quality and the added value of Denim clothing.

Description

technical field [0001] The invention relates to the technical field of biological enzyme preparations and textile auxiliaries, in particular to an anti-dyeing and stabilizing additive composition, a preparation method and application thereof, and a compound cellulase and application thereof. Background technique [0002] Cellulase is a multi-component mixed protein produced by organisms. Under appropriate conditions, it is a general term for biocatalysts that can hydrolyze insoluble cellulosic materials into soluble sugars. Cellulase has the physicochemical properties and quaternary structure characteristics of protein. It not only makes simple peptide bonds composed of many amino acids, but also has different amino acid arrangement sequences and main chain structures (α, β) for different acids, forming huge molecules with very complex main body conformations. Its delicate and complex motif conformation determines some unique properties of the enzyme, such as high catalytic...
