Herein, we propose a biorefinery concept for the production of man-made cellulosic fibres from waste newsprint using environmentally friendly technologies. Newsprint represents one of the most challenging ligno-cellulose substrates as it comprises mostly virtually unrefined wood pulp. Spinning dopes were prepared with pulps obtained through kraft pulping and alkaline glycerol pulping at varying intensities. The solubility of kraft deinked newsprint pulps in the ionic liquid 1,5-diazabicyclo[4.3.0]non-5-enium acetate ([DBNH]OAc) was not promising and resulted in solutions of poor spinnability. In contrast, dopes prepared from alkaline glycerol pulping showed promising visco-elastic properties and the spun fibres possessed high tensile properties that are comparable to commercial Lyocell fibres made from highly refined dissolving pulp. The structural features of these fibres in terms of degree of orientation, crystallinity and the moisture sorption behaviour were analyzed and are discussed.

再生新闻纸中的高性能人造纤维素纤维

在此，我们提出了一种生物精炼概念，即使用环保技术从废新闻纸生产人造纤维素纤维。新闻纸代表了最具挑战性的木质纤维素底物之一，因为它几乎包含了几乎未精制的木浆。用通过牛皮纸制浆和碱性甘油制浆获得的纸浆以不同的强度制备纺丝原液。牛皮纸脱墨的新闻纸浆在离子液体1,5-二氮杂双环[4.3.0]非-5-乙酸铵（[DBNH] OAc）中的溶解度不理想，导致溶液的可纺性差。相反，由碱性甘油制浆制备的浓液显示出有希望的粘弹性质，并且纺制的纤维具有与由高度精制的溶解浆液制得的商业Lyocell纤维相当的高拉伸性质。
