Improvement of wrinkle-resistant treatment by nanotechnology

Abstract

In this research, the non-formaldehyde wrinkle-resistant treatment of cotton fabrics has been investigated using the 1,2,3,4-butane tetracarboxylic acid as cross-linking agent and sodium dihydrogen hypophosphite as catalyst together with nano titanium dioxide as co-catalyst compound. The effect of changes in the concentration of 1,2,3,4-butane tetracarboxylic acid and nano titanium dioxide on the wrinkle recovery angle, tensile strength, tearing strength and bending length of cotton fabrics was evaluated. It was found that the addition of nano titanium dioxide could enhance the wrinkle resistance and decrease the bending length of the cotton fabric with little effect on the tearing and tensile strength of the treated fabrics.
