ABSTRACT:
Textile fabrics and garments having a random, irregular heather-like appearance are produced by impregnating a textile fabric with an aqueous pretreaement composition comprising a fiber reactive cationic compound, aging the impregnated fabric in a moistened state for about 4 to 24 hours to allow the fiber reactive cationic compound to react with the fibers of the fabric, rinsing the fabric to remove unreacted cationic compound, immersing the fabric in an aqueous bath at a pH of less than 7 and gradually introducing dyestuffs to the bath over a period of at least 15 minutes, and fully exhausting the dyestuffs onto the fabric. The process is applicable for dyeing either piece goods or garments. Where the fabric is in the form of garments, it is preferred that the aging be carried out by storing the garments in an insulated sealed container.
