摘要
经过30多年的研究,lyocell纤维的生产工艺已成为最环保的人造纤维素纤维的生产工艺。在生产过程中,浆料被直接溶解在有机溶剂(NMMO)中,所用溶剂几乎可以全部回收并再利用。由于采用闭环生产过程,生产过程对可能进入体系的化学试剂及污染物极为敏感。精密的生产过程首次生产出商品化的高度复合的填充纤维Tencel纤维。生产Tencel R100纤维所用的功能化填料来源天然,并可促进这种新型纤维防火层的形成。Tencel R100已经作为防火材料用于美国床垫市场,而且在个人防护服及其他领域也展现出应用潜能。纤维素、环保生产工艺及天然功能性填料的结合完善了Tencel纤维的高度可持续性发展。
Over 30 years of research have enabled the lyocell process to become the most environmentally friendly production process for man-made cellulosic fibers. The process utilizes the direct dissolution of pulp in an organic solvent ( NMMO), which is almost completely recovered an re-used. Due to closed loop production, the process is highly sensitive to any additional chemicals or contaminations that may be introduced into the system. However, precise process adaption enabled the production of highly incorporated (filled) Tencel fibers on commercial scale for the first time. The functional additive used for the production of Tencel R100 is of natural origin and adds flame barrier forming properties to this novel fiber-type. Tencel R100 is already successfully used as flame barrier material in the US mattress market and shows additional potential for applications in personal protective clothing and other interesting areas. Combining cellulose, an eco-friendly production process and a functional additive of natural origin perfectly complements the high level of sustainability of Tencel fibers.
