• Regenerated fibers have garnered considerable attention in the textile industry because of their inherent biocompatibility and biodegradability. Polysaccharides are abundant renewable biomass resources, and their structural diversity depends on the constituent monosaccharides and linkage styles; thus, the resultant fibers can exhibit a wide range of performance and functions. However, most conventional studies and applications have only focused on β -1,4-glucan (cellulose), and other polysaccharides have not been fully explored. This focus review covers two specific polysaccharides: β -1,3-glucan (curdlan) and α -1,3-glucan. In particular, their characteristic fiber properties are introduced with insights related to the different structures of crystalline and molecular chains. Moreover, the appropriate parameters for dry-jet wet spinning of these polysaccharides are described, such as the concentration of the dope, the appropriate spinning and coagulation solvents for each polysaccharide, and the post-treatment method for the regenerated fibers. Regenerated fibers of β -1,3-glucan (curdlan) and α -1,3-glucan were fabricated by dry-jet wet spinning, and the fiber properties and structures are summarized in this review. The flexible and water-absorbent curdlan and the stiff and strong α -1,3-glucan would be utilized in different applications from conventional cellulose. As a new type of post-treatment, a two-step stretching method in water was developed for α -1,3-glucan by utilizing its crystal transition. This can be applied to various polysaccharides for future production of high-performance fibers.
