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。
Describes the recent advances in the manufacture of cellulose fibers using ionic liquids as one of the most well-studied new materials presently studied. Using ionic liquids can increase processing efficiency. Compared with the NMMO method, the dissolution step is easier to control and the process is inherently safe and produces fibers of different properties. Fibers made with ionic liquids have shown similar properties to NMMO and viscose-made fibers in terms of strength and elasticity. The process can be designed to produce both fibrillated fibers, but also to create non-fibrillated fibers, designed for textile use. The flexibility of this design fiber has the potential of large-scale application of this new technology in future textile and industrial applications.
