METHOD OF DYEING POLYESTERE TEXTILE WOVEN BY THICK FINENESS FILAMENT AND POLYESTERE TEXTILE USING THE METHOD

摘要

PURPOSE: A method for dyeing a polyester fabric of thick fineness is provided to clearly express two tones on the surface of the fabric and to use the polyester fabric in industrial fields. CONSTITUTION: A method for dyeing a polyester fabric of thick fineness for two-tone expression comprises: a step of dipping a polyester fabric in a refining solution containing 3-12 wt% of sodium hydroxide(NaOH) and 5-12 wt% of anionic surfactant for 20-50 minutes and washing the polyester fabric with water(S1); a step of dipping the polyester fabric in hot water at 80-100 deg.C. for 30-60 minutes(S2); and a step of dipping the polyester fabric in a dyeing solution and washing the polyester fabric with water(S3).
