多元羧酸无醛抗皱整理剂的研究进展

RESEARCH DEVELOPMENT OF FORMALDEHYDE-FREE CREASE RESIST AGENT-POLYCARBOXYLIC ACIDS

棉织物不断增长的市场需求使无醛防皱整理显得非常迫切,多元羧酸被认为是最有发展前景、可以替代传统的N-羟甲基化合物的无醛防皱整理剂。本文对可用于防皱整理的多元羧酸的结构特征、种类、与棉织物的交联机理及催化剂进行了详细的综述。1,2,3,4-丁四酸被认为是多元羧酸中最有效的交联剂,但由于其价格昂贵阻止了其在纺织工业中的商业化应用,本文也提出了几种降低整理成本的方法。

The increasing demand in the market for easy care cotton apparel has made the need for formalde- hyde-free anti-creasing finishes more urgent. Polycarboxylic acids appear to be the most promising nonformalde- hyde anti-creasing finishing agents to replace the traditional N-methylol reagent. The structure character, mech- anism of crosslinking reaction for cotton fabrics, type of anti- creasing agent which have been studied, as well as catalysts are reviewed in detail. 1,2,3,4 - Butanetetracarboxylic acid(BTCA) is considered as the most effic- tive crosslinking agent among the acids investigated, but its exceedingly high cost has prevented its use in the textile industry on a commercial scale. Methods taken to reduce the cost are also presented in this paper.
