Wrinkle-resistant finishing of cotton fabric with BTCA - the effect of co-catalyst

摘要

Fabrics treated with dimethyloldihydroxylethyleneurea (DMDHEU) are susceptible to formaldehyde release. High concentrationsnof formaldehyde have been reported to cause cancer in animal studies. Due to the toxicity of DMDHEU, thenpolycarboxylic acid class of non-formaldehyde crosslinking agents used for wrinkle-resistant treatment has been introduced.nAmong various researches, 1,2,3,4-butanetetracarboxylic acid (BTCA) is a desirable reactant when catalysed withnsodium hypophosphite (SHP). The characteristics of TiO2 or nano-TiO2, acting as a co-catalyst in a BTCA wrinkleresistantnfinishing system are examined in this study. Surface morphology and molecular structure of cotton specimensntogether with the wrinkle-resistant, UV protection, yellowing, tensile and tearing properties of the treated specimens arenalso evaluated.
