چکیده    The objective of the given study was to obtain eco-friendly finishes and optimized application parameters of easy-care finishing. easy-care finishing of cotton/polyester blend fabric was done at different ph values and resin concentrations using three different types of cross-linking finishing resins: modified dihydroxyethylene urea (i),modified dimethyloldihydroxyethylene urea (ii),and modified n-methyloldihydroxyethylene urea (iii). optimum mechanical properties (wrinkle recovery angle wra; 252 (w+fo) and tensile strength ts; 2143 n) were observed at 30 g/l of resin i and 5.0 ph. at these conditions resin i showed lowest free formaldehyde content (3.07 mg/kg). formaldehyde (hcho) was extracted,derivatized,and estimated as dnph-formaldehyde using hplc through a c18 column. no appreciable difference in easy-care properties were observed when cotton/polyester blend fabric was finished,in optimized conditions,with resins ii and iii,except slightly increased hcho.
