Abstract

Novel technology for regenerated cellulose fiber production from cellulose solutions in orthophosphoric acid has been developed. These solutions are found to be suitable for regenerated cellulose fiber spinning with the following physical and mechanical properties of fibers: strength, 22-30 cN/tex; elongation, 20-10%; elastic modulus, 600-1200 cN/tex. The fibres thus obtained are highly hydrophilic (hygroscopicity is about 10-18%). The samples of nonwoven fabric based on new regenerated cellulose fiber have been made by needlepunching technique. The technology has been scaled up to pilot plant machine with the capacity of 3000 kg per year.
