摘　　要：为了解决传统亚麻粗纱煮漂工艺对纤维损伤大、环境污染严重等问题,提出了超临界CO_(2)生物酶煮漂法,探讨了不同生物酶对粗纱煮漂性能的影响。结果表明:木聚糖酶、纤维素酶和葡萄糖氧化酶复配煮漂后,亚麻粗纱的分裂度较高,在一定程度上增加了纤维的粗糙度;由红外光谱分析得知,半纤维素、果胶和木质素含量发生变化;煮漂后纤维的结晶度降低为68.72%,热稳定性提高。In order to solve the problems of large fiber damage and serious environmental pollution caused by traditional scouring and bleaching process of flax roves,a biological enzyme scouring and bleaching method by supercritical CO_(2) is proposed,and the influence of different biological enzymes on scouring and bleaching performance of flax roves is discussed.The results show that the splitting degree of flax roves after scouring and bleaching with a combination of xylanase,cellulase and glucose oxidase is higher,which increases the roughness of the fiber to a certain extent.The contents of hemicellulose,pectin and lignin change by infrared spectrum analysis.Moreover,the crystallinity of the fiber decreases to 68.72%,and the thermal stability of the fiber improves.
