提高聚乙烯醇─丝蛋白共混纤维白度及色泽鲜艳度的探讨

How to Improve the Whiteness and Brightness of Polyvinyl Alcohol-Fibroin Fibre

探讨了双氧水、保险粉漂白及增白剂增白工艺条件对聚乙烯醇─丝蛋白共混纤维白度及染色鲜艳度的影响。结果表明，双氧水漂白所获得的白度比保险粉漂白的高。如果要求有较高白度，可采用双氧水─保险粉双漂工艺。

Discusses the effect of the whitening conditions of hydrogen peroxide, hydrosulphite or whitening agent on the whiteness and brightness of polyvinyl alcohol-fibroin blended fibre. The results show that the whiteness obtained from hydrogen peroxide bleaching is better than that from hydrosulphite, while still higher level whiteness can be achieved by double bleaching with hydrogen peroxide and hydrosulphite.
