Stellera chamaejasme Roots as Raw Material for Pulp Production
Cellulosic pulps were prepared from Stellera chamaejasme roots using soda, soda-anthraquinone (soda-AQ), and kraft pulping processes. S. chamaejasme is composed of 73.5% holocellulose, 39.7% α-cellulose, and 17.6% lignin, similar to wheat straw and other

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

Merging materials processing tricks inspired by mussel and mistletoe fiber fabrication, solutions of cationic mussel byssus proteins were mixed with modified anionic nanocrystalline cellulose, producing distinctive core‐shell condensates. Simple processing of condensate suspensions using freeze‐drying produced hierarchically structured porous protein ...
