Method for scouring and bleaching cotton fabric with combined enzyme preparation

A method of using compound enzyme preparation to execute same bath boiling-off and bleaching to cotton fabric, relates to a plurality of alkaline enzyme preparation in the application technique field of the cotton fabric boiling-off and bleaching technique. The enzyme preparation for boiling-off and bleaching is compounded and mixed by horniness enzyme , alkaline pectic enzyme, alkaline xylanase,alkali cellulose enzyme and sugar oxidizing enzyme. The invention adds in the compound enzyme preparation, amylaceum, oxygen bleaching stabiliser RB-3, osmotic agent and JFC triton X-100 under the condition of 55-70 EDG C and ph 8-10 to execute boiling-off to the cotton fabric. After the boiling-off, four acetyl ethylene diamine (TAED) is added in the boiling-off bath to activate hydrogen peroxide to bleach the fabrics for 30min. After the inventive process to cotton fabric, the invention has a high cotton fabric impurity clearance, good fabrics wetting property and high whiteness. The invention is adopted to substitu
