生物基锦纶环保加工技术及其应用

生物基锦纶是指相对于传统石化法聚酰胺纤维,使用蓖麻油裂解法或葡萄糖发酵法等生物法合成加工得到的绿色、环保型聚酰胺纤维。生物基锦纶具有传统锦纶的高强、耐磨、吸湿等优良性能,并在原料来源可持续、功能性等方面存在很大优势,但多数由于成本过高或提取工艺不过关而未能实现产业化。近年来,蓖麻油裂解工艺和葡萄糖生物发酵工艺取得了飞速的发展,尤其是我国大大提高了微生物发酵中关键酶的效率,使生物基锦纶单体的成本和质量都得到控制,有助于打破长期以来国际公司对聚酰胺原料单体二元胺的市场垄断,具有现实的产业化前景,在化纤工业、汽车行业和军事装备领域都有广阔的应用前景。

Environment-friendly processing technology and application of bio-based polyamide fiber

Relative to conventional petrochemical polyamide fiber, bio-based polyamide fiber is processed and obtained by a biological method such as castor oil cracking or glucose fermentation, and is green and environmental friendly. Bio-based polyamide fiber has excellent properties such as high strength, wear resistance and moisture absorption equivalent to conventional nylonfiber, and has big advantages in aspects of sustainable sources of raw materials, function, etc. But most of them is failed to industrialize due to overhigh cost and poor extraction process. In recent years, the castor oil cracking process and the glucose fermentation process have been developed rapidly. Especially the efficiency of key enzymes in the microbiological fermentation has been greatly improved domestically, so that the quality and cost of biomass polyamide fiber monomers are controlled, which helps to break long-term concentrated  market control of international companies to diamine monomer of polyamide materials. It also has a realistic industrialization prospect and broad application prospects in fields of chemical industry, automotive industry and military equipment.
