表面活性剂对新型纺织品的作用

Interaction of surfactants on new textile products

溶胶凝胶和等离子体处理技术用于开发织物的3项新性能或改良性能:低透明度、高上染率及高疏水性纺织品。通过评估表面活性剂对这三种新型纺织品的作用,发现现有洗涤配方,尤其是护色专用洗涤剂,可维持织物不透明性,并改善了最初未处理织物的白度。然而现有洗涤剂并不能很好维持织物的紫外吸收值。另一方面,护色专用洗涤剂保留了等离子体预处理织物的原始染色牢度。结果表明:获得疏水性纳米涂层的等离子操作条件比洗涤过程中洗涤剂的使用种类更为关键。洗涤剂配方中氧化剂、pH值、聚集态、不溶性物质以及染料迁移抑制剂的组成比例需优化,以最大限度降低纤维损伤并维持织物性能。

Sol-gel and plasma technologies have been used to develop 3 new or improved properties on textiles： reduced transparency, improved dye uptake, and highly hydrophobic textiles. Interaction of surfactants on these 3 new textile products has been evaluated. It was observed that current detergent formulations are able to maintain the textile opacity and improve whiteness degree from initial non-treated fabrics, especially with color care special detergents. However, UV absorption values are not correctly preserved by current laundry detergents. On the other hand, color care special detergems preserve the original dye fastness on plasma pre-treated textiles. Finally, it has been shown that plasma operational conditions to obtain hydrophobic nanocoatings are more critical than types of detergents used in laundry processes. Oxidants, pH, aggregation state, insoluble builders and the presence of dye-transfer inhibitors on detergent formulations have to be optimized to minimize fiber damage and maintain efficacy of textile properties.
