PBT纤维染色牢度的研究

Study on dyeing color fastness of PBT fiber

通过测试纤维的Lab值,比较纤维b值的不同,对比了PBT纤维与PET纤维的染色牢度,并进一步考察了空白PBT、PET纤维的被沾染的难易。结果显示:PBT纤维的色牢度好于PET纤维;PBT纤维比PET纤维容易被沾染;随着温度的升高,时间的延长,PBT纤维沾色越严重。

In this paper,the PET fibers and the PBT fibers′dyeing color fastness was compared through the different b values by testing the Lab values of the two fibers.And the difficulties of being stained of the blank PBT fibers and the blank PET fibers were further reasearched.The results show:the PBT fibers had better color fastness than the PET fibers,but they were easier stained than the PET fibers.With the increase of the temperature,the ex-tension of the time,the more serious the PBT fibers were stained.
