PRE-TREATMENT COMPOSITION FOR SUBLIMATION TRANSCRIPTION OF COTTON FABRIC AND METHOD FOR SUBLIMATION-TRANSCRIPTION DYING COTTON FABRIC USING THE SAME

摘要

The present invention relates to a pre-treatment composition for sublimation transcription of cotton fabric comprising 5 to 20 wt% of weight polyvalent metal salt, 1 to 5 wt% of hydrophilic surfactant, 5 to 15 wt% of moisture acid polyurethane resin, 1 to 2 wt% of poly aluminum chloride and excess water. The pre-treatment composition improves color developability and wash fastness of cotton fabric printed according to sublimating dye transfer and maintains texture of the fabric.
