Abstract
Although cellulosic fibers are increasingly used in textile products, current methods for production of cellulose-based textiles suffer certain economic and/or environmental drawbacks. We have developed a new, cost-effective and environmentally-friendly (CS2-free) process that overcomes some of the shortcomings of existing technologies. The process is based on a modified method for periodate oxidation of cellulose that is then cross-linked with chitosan and extruded to obtain cellulosic fibers in the form of textile fibers. The produced fibers have low content of aldehyde groups (â¼2Â mmol/g cellulose) and water retention values of 1.5-2.0Â g/g fibers. The new process makes use of both hardwood and softwood pulps, and offers significant yield advantages over the use of dissolving pulp as a raw material. The mechanical, water absorbency and morphological properties of the new textile fibers and their potential applications are discussed. The potential techno-economic and environmental benefits of the process are summarized.
