Some issues in moisture-wicking finishing



吸湿排汗织物(纯纺和混纺)的染整加工工艺技术,基本上可参照常规涤纶和涤棉混纺织物的工艺流程和技术条件。不过吸湿排汗涤纶纤维的特殊结构形态必须保证不会受到损伤,否则就会影响产品的性能,主要关注的问题是: 1. Moisture-absorbing and sweat-wicking polyester fibers are mainly special-sha…

吸湿排汗织物(纯纺和混纺)的染整加工工艺技术,基本上可参照常规涤纶和涤棉混纺织物的工艺流程和技术条件。不过吸湿排汗涤纶纤维的特殊结构形态必须保证不会受到损伤,否则就会影响产品的性能,主要关注的问题是:

1. Moisture-absorbing and sweat-wicking polyester fibers are mainly special-shaped fibers, and most of the surfaces have micro-groove structures. The surface area of ​​the same fineness is 20-30% larger than that of conventional round fibers. Therefore, high-temperature alkali treatment in pre-treatment should be used with caution. consider �</p

2、基于上述同样原因,分散染料染色时的上染较快;因此,与棉混纺织物要染得良好的同色性,对原来染棉(或染涤纶)的处方必须作适当的调整。

3. When softening moisture-wicking fabrics, it is not advisable to use hydrophobic varieties, otherwise it will affect the wicking effect of the fabric and reduce its moisture-wicking function. After pure and blended fabrics are treated with moisture-wicking agents, their Moisture wicking properties can be improved, but it is better to choose durable varieties. �</p

4. The newly launched moisture-absorbing and perspirant agent is mainly a compound composed of water-dispersed polyester as the main component. The origin of the development of this additive can be traced back to the 1960s and 1970s, when it was first introduced by the British ICI company. Permalose to the market, of which PermaloseT is used for polyester fabrics and PemaloseTG is used for polyester-cotton blended fabrics �为了配合吸湿排汗织物的掀起,吸湿排汗整理剂应运而生,是原来老品种的新用途的开发应用呢,还是水分散性为主组分的新复配产品暂时无法断定� �</p

Water-dispersible polyester is a block copolymer of terephthalic acid (ethylene glycol) and polyethylene oxide. Its schematic formula is as follows:</p

上述嵌段共聚物的分子量一般小于30000,其中聚环氧乙烷的分子量约为1000左右。视嵌段共聚物的分子量大小、熔点为50-6O℃左右,易分散于水中成分散体,浓度高时则呈凝胶状。

The molecular structure of the above-mentioned dispersed block copolymer has the same benzene ring as the molecular structure of the polyester fiber. At high temperatures, due to the movement of the molecular chain, the benzene rings of the two easily generate intermolecular structures (π electrons), forming a strong anchor point. The hydrophilic polyalkylene oxide segments are anchored on the surface of the polyester fiber, turning the original hydrophobic surface of the polyester fiber into a durable hydrophilic surface. �</p

水分散性嵌共聚物的应用方法,有轧烘焙工艺和高温浸渍工艺两种:前者需160-170℃热处理3-5分钟,后者需130℃处理30分钟。织物上的施加量(以有效活性成分计)为1-1.5%左右。处理效果以高温浸渍工艺较好且效果稳定。经吸湿排汗整理后,除能明显提高吸湿排汗功能外,尚有抗静电和易去污效果。
