【Product Description】

Traditional refining requires the use of chemicals such as strong alkali or soda, which not only hardens the feel but also has a negative impact on the environment. Traditional pre-treatment not only involves managing a large amount of chemicals, but also involves multiple washes, high-temperature treatment, sewage discharge, and fiber damage, all of which have an impact on the factory. Composite refining enzymes are used in the pre-treatment process of cotton knitted fabrics, which can effectively remove pectin, wax, and other associated impurities on cotton fabrics, while achieving good moisture absorption and leveling effects

The use of composite refining enzymes does not require the addition of additional additives, such as penetrating agents, defoamers, etc. If chelating agents such as chelating agents, dispersants, and water softeners are used in the alkaline cooking process, then biological refining Equal addition and use are also required in the process
