Abstract：
Currently the textile industry relies strongly on synthetic fibres and cotton, which contribute to many environmental problems. Man-made cellulosic fibres (MMCF) can offer sustainable alternatives. Herein, the development of Lyocell-type MMCF using bacterial cellulose (BC) as alternative raw material in the Ioncell® spinning process was investigated. BC, known for its high degree of polymerization (DP), crystallinity and strength was successfully dissolved in the ionic liquid (IL) 1,5-diazabicyclo[4.3.0]non-5-enium acetate [DBNH][OAc] to produce solutions with excellent spinnability. BC staple fibres displayed good mechanical properties and crystallinity (CI) and were spun into a yarn which was knitted into garments, demonstrating the potential of BC as suitable cellulose source for textile production. BC is also a valuable additive when recycling waste cellulose textiles (viscose fibres). The high DP and Cl of BC enhanced the spinnability in a viscose/BC blend, consequently improving the mechanical performance of the resulting fibres, as compared to neat viscose fibres.
摘要：
目前纺织业对合成纤维和棉花的依赖非常大,这导致了许多环境问题。人造纤维素纤维（MMCF）可以提供可持续的替代品。在这里，研究了在Ioncell®纺丝过程中使用细菌纤维素（BC）作为替代原料的Lyocell型MMCF的开发。BC,以其高聚合度（DP）而闻名，将结晶度和强度成功地溶解在离子液体(IL)1,5-二氮杂双环[4.3.0]非5-乙酸硒[DBNH][OAc]中,制得具有优异可纺性的溶液。BC短纤维表现出良好的机械性能和结晶度（CI），并纺成纱线，然后针织成服装，证明BC作为纺织品生产合适的纤维素来源的潜力。当回收废纤维素纺织品(粘胶纤维)时,BC也是有价值的添加剂。BC的高DP和Cl提高了粘胶/BC共混物的可纺性，从而提高所得纤维的机械性能，与纯粘胶纤维相比。
