ABSTRACT:
When silk fabrics, pre-treated with swelling agents, are printed by heat transfer techniques, the fabric will yellow. The invention eliminates yellowing by pre-treating said silk fabrics with a liquid or solid impregnating agent, dissolved or dispersed in water, then drying the fabric, and adding before, during or after the pre-treating an optical brightening agent of the type normally used for polyester.
The impregnating agent can alternatively be applied to the fabric in a water-free condition before or during dyestuff transfer, and an optical brightener may be added.
It is further contemplated to use easily migrating dyestuffs which are transferred to the fabric at relatively very low temperatures, and to avoid dyestuff migration by pre-treating the silk fabric with solid impregnating agents.
All these techniques produce deep and brilliant shades; the prints have excellent fastnesses.
