本文介绍了一种生产高强高模纤维素纱线的新工艺。纤维素的一种新的直接溶剂已经被发现，导致液晶溶液。这种新的溶剂，超磷酸，能迅速溶解纤维素。这些液晶溶液被气隙纺成高度有序的纤维素纱线。讨论了从溶解到纱线表征的各种工艺步骤. ...Zie:总结
The presen thesis describes a new process for manufacturing high tenacity and high modulus cellulose yarns. A new direct solvent for cellulose has been discovered, leading to liquid crystalline solutions. This new solvent, superphosphoric acid, rapidly dissolves cellulose. These liquid crystalline solutions are air gap spun to form highly ordered cellulose yarns. The various processs teps from dissolution to characterization of the yarns are discussed. ... Zie: Summary
