This product is a major reform of the traditional dyeing and finishing process. It can replace the additives such as caustic soda, scouring agent, penetrant, oxygen bleaching stabilizer, chelating dispersant, degreasing and wax removal in the traditional process. Compared with the traditional ds-b and d-sb processes, the one bath process with one steamer for both scouring and oxygen bleaching without changing the equipment of the dyeing plant can effectively reduce the discharge of three wastes. This product does not contain formaldehyde, APEO and other European textile strong certification chemical harmful elements, which is conducive to ecological protection.
