超支化聚合物在印染工业中的应用

超支化聚合物具有特殊的结构和性能.其包含大量的枝化结构,可提高溶解度;其大量的链端官能团.可提高反应性.因此,超支化聚合物在纺织印染行业中的研究和应用受到广泛关注,如超支化聚合物可作为双氧水漂白稳定剂,在涂料染色和印花中作为黏合剂,与聚丙烯共混纺丝改善其可染性,对棉、麻、真丝等天然纤维改性以实现无盐染色,对纤维表面进行功能性后整理,以及利用其絮凝和螯合作用而用于印染废水处理等.

Application of hyperbranched polymers to dyeing and finishing industry

Hyperbranched polymers have unique structures and properties, such as many branched structures can increase the solubility of the polymers, and many end functional groups can increase reactivity, therefore, their apphcations to dyeing and finishing industry attract serious attentions. This paper covers various available applications, such as in hydrogen peroxide bleaching as a stabilizer, in pigment dyeing and printing as a binder, in PP polyblending to improve dyeability, in salt-free dyeing of natural fibers of cotton, flax, silk as a modifier, in functional finish as a finishing agent, in wastewater treatment as a floccu-lating and chelating agent.
