Process for preparing burn-out effects on textile materials

摘要

An improved process for preparing white or colored burn-out effects on textile materials containing hydrophobic fibers and cellulose fibers which process comprises applying to the material a dyeing liquor or printing paste containing at least one disperse dyestuff for dyeing the hydrophobic fibers alone or mixed with dyestuff for dyeing the cellulose fibers, applying a burn-out agent to the textile material in the form of a pattern, and then heat-treating the textile material at about 100 DEG to 240 DEG C. whereby the dyestuff is fixed and the burnout effect is produced, wherein the improvement comprises said dyeing liquor or print paste contains at least one disperse dyestuff which is discharged by the burn-out agent.
