THE EFFECT OF 1, 2, 3, 4 BUTANETETRACARBOXYLIC ACID AND TIO2 TREATMENT COTTON ON UV PROTECTION

Abstract

Cotton fabrics are modified chemically to add durable press properties. For that, the textile material is treated with crosslinking agents in combination with an appropriate catalyst. Polycarboxylic acids in combination with inorganic phosphorus-containing salts have proven to be one of the most effective formaldehyde-free system capable of imparting durable press properties to cotton fabrics. In this work the 1,2,3,4 butanetetracarboxylic acid (BTCA) and sodium hypophosphite NaH2PO2 . H2O (SHP) were used to treat cotton fabric in order to get easy care properties. In addition, we study the behavior of BTCA as bonding agent for particles without any affinity for the cellulosic fibres. This research focuses on determining the influence of BTCA on the TiO2 nanoparticles loss of the fabrics during washing treatments and the difference of UV protection using or not using BTCA as a linking agent in the treatment. The scanning electron microscopy was used to verify the presence of the TiO2 on the cotton fabric before and after the laundering. We conclude that with BTCA, more TiO2 nanoparticles remain on the fabric surface. It was shown that the UV protection of treated fabric using BTCA as a binder is lower than treated fabric only with TiO2 nanoparticles.
