Abstract

In this study, when cotton fabrics dyed with Direct dyes are treated under various resin concentration 2, 4, 8, 12, $14\%$ with ureaformaldehyde(UF) and melamineformaldehyde(MF) resin which can be imparted the crease recovery to textiles, chang of properties on lightfastness, washfastness, crease recovery, breaking strength, etc. and color changes are investigated. the results are as follows 1) Color difference(${\Delta}$E) increased but K/S value decreased according to the increase of resin cone. such tendency showed that MF treated fabrics and soaping fabrics were evident than UF treated fabrics and non-soaping fabrics. 2) In lightfastness, ${\Delta}$E and K/S value of resin treated fabrics were reduced as compared with untreated fabrics according to the increase of resin cone. The lower ${\Delta}$E and K/S value of MF than ${\Delta}$E and K/S value of UF showed low lightfastness of MF. pH of resin treted fabrics was almost unaffected with lightfastness. 3) In washfastness, ${\Delta}$E and K/S value of resin treated fabrics decreased slightly as com-pared with untreated fabricsaccording tothe increase of resin cone. The ${\Delta}$E and K/S value of MF decreased lower than UF. But in the case of the higher resin cone. than about $8\%$, they were not almost differentiated. 4) As resin cone. increased, crease recovery considerably increased but breaking strength and elongation decreased. The fabrics treated with UF were good crease recovery, whereas the fabrics treated with MF were good breaking strength. 5) Soaping appeared to improve the lightfastness, washfastness, crease recovery but appeared to work adverse effect on breaking strength.
