用碱减量原理解决仿毛涤纶华达呢染色“鸡爪印”、“眉毛皱”等染疵

On the Solution for the Crease Mark Based upon the Principle of Alkali Peeling Process during the Dyeing of Wool-like Gaberdine of Polyester

文章认为“鸡爪印”和“眉毛皱”等不匀染疵,系涤纶纤维中的齐聚物在织造和染整加工过程中从纤维内部迁移到纤维表面,而使纤维表面粗糙,影响染色性能。根据碱减量处理的剥皮作用,可以“修整”涤纶纤维,使之条件均匀化。作者详细介绍了针对消除上述染疵的前处理的工艺条件。

The author considers that some dyeing defects such as 'chickclaw marking' and 'brow crease' are mainly due to the migration of the oligomers in the polyester fibre from inner to outer surface when dyeing,and finishing are being carried out, and it also make the surface rough, which affects the dyeing performance. According to the alkaline peeling process, polyester fibre could be 'modified' to make it leveling. The author introduces in details the pretreat-ment methods for preventing and eliminating the defects stated above.
