摘要
描述了采用作为目前研究得最充分的新材料之一的离子型液体制造纤维素纤维的新进展。使用离子型液体能提高加工效率。与NMMO法相比,溶解步骤更容易控制,工艺本质上是安全的,能生产不同性质的纤维。用离子型液体制造的纤维,就强度和弹性而言,已显示出与NMMO和粘胶法制造的纤维相似的性质。可以把工艺设计成既能制造原纤化纤维,又能制造非原纤化纤维,专供纺织用。这种设计纤维的灵活性在未来纺织和产业用途中使这项新技术有大规模应用的潜力。
New developments in manufacture of cellulose fibers with ionic liquits as one of the most thoroughly investigated new materials today are described. The use of ionic liquids enhances the efficiency of processing. Compared with the NMMO process, the dissolution step is more easily controlled, the process is inherently safer, and it enables the production of fibers with very diffcrent properties. Cellulose fibers manufactured with ionic liquids are already displaying similar properties in terms of tenacity and elasticity compared to fibers manufactured by the NMMO and viscose process. The process can be designed such that both fibrillating and non-fibrillating fibers can be manufactured specially for textile application. This flexibility in designing fiber properties gives this new technology the potential for wide-scale use in future textile and technical applications.
