Most of the dyes used at present have the problem of poor color fastness, particularly, the washing fastness is as high as less than 4 grades, the dyes which can be used on acetate fibers and have excellent washing fastness are fewer and fewer, the acetate fiber dyes are very sensitive to temperature, when the dyeing temperature is uneven or too high, poor appearance or color patterns can be caused, and when the dyeing temperature is low, part of the disperse dyes always fail to enter the interior of the fabric in the dyeing process and can only be adsorbed on the surface to form loose colors, and the loose colors seriously influence the washing fastness of the fabric.
The reason for the low washing fastness mainly includes two aspects, on one hand, during the dyeing process of the dye, part of the dye can not enter the fabric and can only be adsorbed on the surface, the dye on the surface is called floating color, the floating color treatment is not clean, other fabrics are easy to be stained in the subsequent washing process, and on the other hand, even if a small amount of dye enters the dye, the dye can be pulled out and adsorbed on the surface of the fabric under the mild action of the detergent.
