废纸的利用对于节约木材资源和减少废物的产生非常重要。已经研究了用于制备纤维素纳米纤维的各种技术，纤维素纳米纤维是最近提出的在造纸工业中具有潜在应用的材料。在本研究中，细纤维的制备使用回收纸浆和纳米工程水逆碰撞处理，并在减压条件下通过过滤制备由这些细纤维组成的片材。细纤维的比表面积测量和光学显微镜观察表明，与原生浆相比，再生浆不容易通过处理而小型化。无论处理次数如何，由5次处理的再生纸浆制备的片材的拉伸强度高于由60次处理的再生纸浆和由原生纸浆制备的片材的拉伸强度。此外，由5倍的再生纸浆生产的片材的密度低于其他片材。
The utilization of waste paper is very important for saving wood resources and reducing waste generation. Various techniques for preparing cellulose nanofibers, which is a material recently proposed for potential applications in the paper industry, have been investigated. In the present study, fine fibers were prepared using recycled pulp and a nanoengineering aqueous counter collision treatment, and sheets composed of these fine fibers were prepared by filtration under reduced pressure conditions. Measurement of specific surface area and optical microscopic observation of fine fibers showed the recycled pulp was not readily miniaturized by the treatment compared with virgin pulp. The tensile strength of sheets produced from recycled pulp by 5 times of the treatment was higher than of those prepared from recycled pulp by 60 times and from virgin pulp regardless of the number of the treatment. Furthermore, the density of the sheet produced from recycled pulp by 5 times was lower than other sheets.
