Abstract

Silk is one of the most desirable textile materials because of its excellent properties such as handle or luster that distinguish them from other fibers. However, it has some minor textile performances such as crease recovery, dimensional stability, rubbing resistance, photo-yellowing stability, etc. So, the crosslinking of silk fabrics has been widely researched to improve their some properties. It is well known that not only 1,2,3,4-butanetetracarboxlyic acid(BTCA) but also citric acid(CIT) can be applied as a crosslinking agent as well as CIT has a price competition compared with BTCA. In general, these multi-carboxylic acid has been introduced as the alternative candidate of formaldehyde containing durable press(DP) dinishing agents such as dimethyloldihydroxy ethylenurea(DMDHEU), the most popular finishing agent. In our previous study, we carefully proposed that the correlation analysis between dTGA peak point temperature(dTPT) and add-on value(%)(AOV) of the crosslinked silk fabrics had some potential to evaluate the catalysts for crosslinking agent, BTCA. In this study, it has been examined the feasibility of novel evaluation method on some catalysts for the crosslinking agent, CIT.
