摘要
本文阐述了利用含腈水合酶的粗酶液处理聚丙烯腈纤维 ,使纤维表面的氰基选择性水解为酰胺基 ,从而提高聚丙烯腈纤维的吸湿性。
The surface of the polyacrylonitrile fibers could be modified by the crude enzymes involved nitrile hydratase. The surfacial nitrile groups of the polyacrylonitrile fibers are selectively hydrolyzed to the corresponding amide. In this case,the hydrophility,anti static ability and dyeing efficiency with acidic dyes of the polyacrylonitrile fibers are all improved.
