Whitening and Anti-phenolic Yellowing One-bath Process of Polyamide and Modified Polyester Blended Fabrics
In order to solve the problems of inefficiency,waste of resources and peculiar odor in the conventional whitening and anti-phenolic yellowing two-bath process of polyamide and modified polyester blended fabrics,the effects of temperature,time,dosage of glacial acetic acid and anti-phenolic yellowing agent N on the whiteness,anti-phenolic yellowing grade and peculiar odor of the fabrics were studied and then compared with those of conventional two-bath process by single factor test.The optimal one-bath process is as follows:the acid fluorescent whitening agent BA267 is 0.3％,the anti-phenolic yellowing agent N is 3.0 g/L,the leveling agent P is 1.0 g/L,and the bath ratio is 1∶10,running for 20 minutes at 95 ℃.The results show that the optimal one-bath process can save water,electricity,steam,acetic acid and other resources,and the whiteness and anti-phenolic yellowing grade of the treated fabrics are similar to those of the conventional process,and the products have no peculiar odor,which can meet the needs of customers for ecological and healthy textiles.
