羊毛再生蛋白-聚丙烯腈共聚纤维染整加工

Dyeing and finishing of the wool regenerated protein-polyacrylonitrile copolymeri fiber

研究羊毛再生蛋白-聚丙烯腈共聚纤维的染整性能与加工工艺。认为染整加工中该纤维的漂白与染色问题具有特殊性，确定了亚铁离子预处理，H2O2漂白的工艺条件，达到了染整加工要求的白度。提出制备一种新型混合染料专门用于该纤维的染色加工的新思路，采用电导法确定阳离子染料与防沉淀剂的质量比按1：7～9混合后，再与酸性染料混合，制备出了该纤维的专用染料，为这种新型纤维品种或类似纤维品种的染料开发与染整加工提供了参考。

The dyeing and finishing properties and processing technique of the copolymerized fiber made of wool regenerated protein and polyacrylonitrile were studied. The fiber was considered to have specific problems in bleaching and dyeing. The process conditions of the pretreatment with ferrous ion and of bleaching with H2O2 were determined, and the whiteness obtained was up to the requirement. A new idea was brought out, that is, to make a new type of mixed dyestuff designed specially for the dyeing of this fiber. The special dyestuff for the fiber was prepared by first mixing cationic dye with anti-precipitator at the ratio of 1：7-9 （by weight） which was determined by employing conductometric method, then mixing with acid dye. This has provided a theoretic reference for dyestuff exploitation of this new type of fiber or similar fibers and fir dyeing and finishing thereof.
