Zusammenfassung:	The invention discloses a pretreatment processing technology of a high-whiteness water-repellent elastic bandage, which utilizes a scouring enzyme KA-M to quickly and effectively remove pectin and lignin in cotton fibers by preserving heat at 60 DEG C, and is beneficial to low-alkali scouring and bleaching of the elastic bandage, and the elastic bandage after continuous steaming and bleaching has good whiteness and good water repellency. The scouring and bleaching reaction is carried out under the low-alkali condition, cotton fibers can be effectively protected, natural cotton wax and grease are effectively reserved, and the water repellency grade of the bandage is larger than or equal to 3; the process is high in production efficiency and small in damage to cotton fibers, and the elastic bandage after steaming and bleaching is high in quality and breaking strength; the COD value of discharged waste liquid is low, the sewage treatment cost is low, the ecological environment is protected, and energy conservati
