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.

First claim

What is claimed is:

1. A continuous poly(glycerol sebacate) (PGS)/alginate fiber forming system comprising:
a feeding tank holding a polymeric solution of alginate and PGS;
a pump receiving the polymeric solution of alginate and PGS from the feeding tank and pumping the aqueous solution of alginate and PGS;
a spinneret receiving the aqueous solution of alginate and PGS from the pump and forming from the PGS and alginate and forming from the PGS and alginate and extruding at least one continuous PGS/alginate fiber;
a first coagulation bath holding a first solution comprising a salt in water and receiving the at least one continuous PGS/alginate fiber from the spinneret;
a first winder receiving the at least one continuous PGS/alginate fiber from the first coagulation bath;
a second coagulation bath holding a second solution comprising distilled water and receiving the at least one continuous PGS/alginate fiber from the first winder;
a second winder receiving the at least one continuous PGS/alginate fiber from the second coagulation bath; and
a bobbin winder winding the at least one continuous PGS/alginate fiber from the second winder onto at least one bobbin.

2. The continuous PGS/alginate fiber forming system of claim 1 further comprising a plurality of draw rolls arranged between the spinneret and the second winder and contacting the at least one continuous PGS/alginate fiber to draw the at least one continuous PGS/alginate fiber and maintain a predetermined tension on the at least one continuous PGS/alginate fiber.

3. The continuous PGS/alginate fiber forming system of claim 1 further comprising a dryer between the second winder and the bobbin winder, the dryer removing water from the at least one continuous PGS/alginate fiber to achieve a predetermined moisture content in the at least one continuous PGS/alginate fiber.

4. The continuous PGS/alginate fiber forming system of claim 1 further comprising an intermingler between the second winder and the bobbin winder, wherein the at least one continuous PGS/alginate fiber comprises a plurality of continuous PGS/alginate fibers, the intermingler receiving and combining the plurality of continuous PGS/alginate fibers into a multifilament yarn round.

5. The continuous PGS/alginate fiber forming system of claim 1 , wherein the spinneret is selected from the group consisting of a monofilament spinneret, a multifilament spinneret, and a sheath core spinneret.
