纤维素/NMMO溶液溶解方法及其溶液的表征

Dissolution Methods of Cellulose in NMMO Solvent and Quality Evaluation of the Solution

Lyocell工艺中浆粕的溶解是十分关键的步骤 ,纺丝溶液的质量直接影响到该溶液的可纺性和丝的质量。本文讨论了有关溶解工艺的一些特点 ,特别着重介绍了目前国外一些公司的溶解方法 ,并结合本课题组的一些研究经验 ,提出了有关表征溶液质量的一些方法。

The dissolving process of cellulose and NMMO is one of key steps in producing Lyocell fiber. The methods, especially three advanced dissolving processes at present, have been discussed. Combined with our experiences in Lyocell process, the quality evaluation of cellulose solution for spinning has also been suggested. It is important for option to the dissolving process and judgment of the solution quality.
