新乡“绿色纤维”项目通过科技成果鉴定

2017-09-05 08:32:02   中国青年网

本报讯(新乡观察记者代娟)8月29日,由中国纺织科学研究院和中纺院绿色纤维股份公司共同承担的年产1.5万吨Lyocell纤维产业化成套技术的研究开发项目在新乡通过科技成果鉴定。由中国工程院院士孙晋良、蒋士成、俞建勇等专家组成的鉴定委员会对项目给予高度评价,认为该万吨级Lyocell纤维产业化成套技术整体已达到国际先进水平。

专家认为,该项目已形成了工艺、装备、安全、自动化控制和工程技术系统一体化集成创新的成套技术。在新乡建成的首条具有自主知识产权、全国产化1.5万吨/年Lyocell纤维生产线,实现了全线连续稳定运行,产品指标达到国外同类产品水平,具备了工程设计、工程实施和产业化快速推广的技术能力。

绿色纤维Lyocell俗称天丝,以树木、竹子等可再生资源为原料,兼具天然纤维和合成纤维的诸多优异性能,已成为高档时装的主要原料,被称为“21世纪的绿色纤维”。

长期以来,Lyocell纤维产业化技术一直被国外垄断。中国纺织科学研究院从1998年开始进行新溶剂法纤维素纤维的研究,从实验室小试到联合新乡白鹭化纤进行千吨级中试,再到成立中纺院绿色纤维股份公司进行万吨级产业化生产,历经18年科研攻关,最终实现了拥有完全自主知识产权的全国产化万吨级Lyocell纤维的产业化技术。???8
