亚麻落麻新型环保脱胶工艺

Novel environmental degumming process of flax noil

对亚麻落麻纤维进行复合生物酶-氧漂加工，测试了煮漂后纤维的强伸性能、长度、白度和毛效，以及试纺纱线的质量指标。结果表明：25mm长度的短纤维率为13．0％，低于传统氯漂工艺的13．2％；主体纤维（长度25～75mm）含量为43．4％，比传统的氯漂工艺40．5％提高了2．9％；强度与传统工艺相当，断裂伸长率4．6％，优于传统工艺4．2％；新工艺纺制的14．5tex（40^s）麻55％，棉45％混纺纱的强伸性指标均高于传统工艺和国家标准；新工艺污水COD值低。

A novel environmental-protection degumming process is carried out on flax noil fiber, and the physical indexes like strength, elongation property, whiteness and capillary effect of treated fiber are tested. The treated fibers are spun into yarns, and their quality indexes are also tested. The outcomes show that compared with the traditional chlorine degumming process, the yarn made with the novel degumming process features good indexes with short fiber content （25 mm） of 13.0%, proportion of main fibers （25-75 mm） of 43.4%, comparable strength, superior elongation at break of 4.6%.The strength and elongation of the mixture yarn of 14.5 tex （40^s） 55 flax/45cotton with this new degumming process are better than those with the traditional process. Sewage from the new degumming process has lower COD value than that from the traditional process.
