Abstract:	In pursuit of sustainable alternatives to fossil-based materials, cellulose-based products, such as regenerated cellulose and cellulose derivatives, have attracted increasing attention. These materials offer biodegradability, biocompatibility, and a wide range of adjustable properties. However, their production relies on dissolving pulps, which are significantly more expensive than standard paper-grade pulps due to high raw material and processing costs. In this study, a potential route for converting standard bleached chemical pulps into more reactive cellulose was investigated, targeting applications in cellulose derivatives and regenerated materials. The method is based on acidic treatment followed by cold alkali dissolution and precipitation. Results show increased chemical reactivity and partial hemicellulose removal, suggesting a promising path toward low-cost alternatives to conventional dissolving pulp. [ABSTRACT FROM AUTHOR]
