摘要:

针对果胶酶处理对天然彩色棉纤维性能和结构的影响,对天然彩色棉纤维的吸湿性、强力和色差以及脂蜡质含量进行测试,分别采用扫描电子显微镜和生物显微镜观察纤维的表皮结构以及色素分布,并与碱处理作比较。结果显示:果胶酶处理不仅符合天然彩色棉的环保特性,且处理后天然彩色棉纤维的吸湿性能明显改善,纤维强力没有明显的下降,纤维的结构未被破坏,纤维内保留了大量脂蜡质,纤维色素没有明显流失;果胶酶处理更适合用来改善天然彩色棉的吸湿性。

Abstract: For studying the effects of pectinase treatment on structures and fiber properties of naturally colored cotton fiber,the moisture absorption,fiber strength,chromatism and waxy materials content of the treated samples were tested.Surface structure and pigment distribution of the samples before and after treatment were observed by scanning electron microscope and bio-microscope respectively,and compared with those by alkali treatment,The results showed that pectinase treatment is beneficial to environmental protection of naturally colored cotton,improves its moisture absorption significantly without noticeable adverse effect on the fiber strength and structure,or the contents of waxy substance and pigments.So pectinase treatment is more suitable for improving the moisture absorption of naturally colored cotton.
