Factors affecting the rebound of four-way stretch fabrics
1、原材料:氨纶生产厂家比较多,不同厂家价格、产品质量差异较大,可根据客户对回弹性要求,选择合适的产品。 2、前处理、染色:加工过程不要使用溶剂型助剂、强碱,避免长时间高温、大张力加工工艺,减少氨纶损伤。 3、后整理:选择合适的加工规格、适量柔软剂,可有效保证织物的回弹性。 The effect of warp and weft density on res…
The biggest nemesis of reactive dye dyeing is H2O2
活性染料耐H202稳定性很差,染浴中一旦有H202带入,染料的活性基团就会遭到破坏,造成色差、色花等染疵,因而染色前必须将织物及水浴中的H202清除。生物酶脱氧法快捷有效,而且节能、减排、增效优势突出。 </p 1. Question raising</p Pure cotton knitted gray fabrics usually cont…
Thermal migration phenomenon of disperse dyes
分散染料染色后的涤纶在高温处理(如定形)中能产生一种受热迁移的现象,也就是染后泳移。 产生热迁移的现象是纤维外层有残存的助剂。在高温或长期贮存的条件下,助剂能将染料吸引溶解,并将染料运动到纤维表面。残存助剂主要来自下面两个方面: (1)纺丝和织造时加入的抗静电剂等。 (2)染色和后处理时加入的抗静电剂、渗透剂、防污染剂和柔软剂等。 纺丝、织造和染色时加入的助…
