This patent describes a process for creating textile fabrics and garments that exhibit a random, irregular heather-like appearance. The method involves impregnating a textile fabric with an aqueous pretreatment composition containing a fiber reactive cationic compound. The fabric is then aged in a moistened state for 4 to 24 hours, allowing the compound to react with the fibers. After rinsing to remove unreacted compounds, the fabric is immersed in an aqueous bath at a pH of less than 7, where dyestuffs are gradually introduced over at least 15 minutes, ensuring full exhaustion onto the fabric. This process is applicable for dyeing both piece goods and garments, with a preference for aging garments in an insulated sealed container.
