Abstract
A manufacturing process includes spinning at least one continuous poly(glycerol sebacate) (PGS)/alginate fiber from a polymeric solution comprising PGS and alginate in water, drafting the at least one continuous PGS/alginate fiber in at least one coagulation bath, and drawing the at least one continuous PGS/alginate fiber from the at least one coagulation bath. A yarn includes at least one continuous PGS fiber. A continuous poly(glycerol sebacate) (PGS)/alginate fiber forming system includes a feeding tank holding a polymeric solution of alginate and PGS, a pump, a spinneret, a first coagulation bath, a first winder, a second coagulation bath, a second winder, and a bobbin winder, the system forming at least one continuous PGS/alginate fiber from the polymeric solution of alginate and PGS.
