Non-ironing finish of cotton/polyurethane dyed fabric is introduced. The effects of setting tem- perature, resin concentration and technological process on elasticity, strength, shrinkage rate, flatness and color change of treated cotton/polyurethane dyed fabric are studied. According to ASTM D 3107-2011, the residual elongation rate （30 min） at constant elongation of treated fabric is no more than 8%, and elastic recovery rate （30 rain） is no less than 50%. According to AATCC 135--2014（1）111A（i）, shrinkage rate of treated fabric is -4%-0. According to ASTM D1424-2013, the tearing strength of treated fabric is no less than 0.77 kg （1.7Ib）. According to ASTM D 5034-2013, the tensile strength of treated fabric is no less than 13.61 kg （30 Ib）. According to AATCC 124-2011, the flatness of treated fabric is no less than Grade 2.8. According to JIS L1041-2011, the formaldehyde content of treated fabric is no more than 75 mg/kg. The treated fabric can meet the requirements of wear performance, and can meet the re- quirements of customers for fabric.
