Compositions and methods that introduce variations in color density into
cellulosic fabrics, particularly indigo dyed denim
摘要:
Aqueous processes and compositions of the invention for obtaining a "stone-washed", distressed or "used and abused" look in clothing, particularly in the panels and seams of denim jeans and jackets involve compositions that are stone-free that avoid mechanical abrasion of the fabric. In particular, the process and composition of the invention used to obtain the distressed, "stone-washed" or "acid washed look" are free of common pumice or pumice-bleach compositions, used in large institutional-size laundry machines, and rely solely on the chemical action of aqueous treatment compositions. The aqueous treatments can be made from liquid or solid concentrates.
