## Abstract Novel cellulose hydrogels were synthesized through a βoneβstepβ method from cellulose, which was dissolved directly in NaOH/urea aqueous solution, by using epichlorohydrin as crosslinker. Structure and properties of the hydrogels were characterized by using SEM, NMR, and water absorptio
## Abstract **Summary:** Novel regenerated cellulose fibers have been successfully spun from the cellulose dope in NaOH/urea aqueous solution, which could rapidly dissolve cellulose. The fibers possess circular crossβsections as well as relatively high molecular weight, and a crystallinity index wi
