Abstract
Disclosed herein are polyesters and fibers made therefrom. The fiber comprises a polymer, poly(trimethylene furandicarboxylate) (PTF), and PTF based copolymers.
Claims14
A fiber comprising a polymer, wherein the polymer comprises poly(alkylene furandicarboxylate) obtained by polymerization of reaction mixture comprising furan dicarboxylic acid and a C2 to C12 aliphatic diol.
A method of making a fiber comprising:
- a. providing a polymer composition comprising poly(alkylene furandicarboxylate) obtained by polymerization of reaction mixture comprising furan dicarboxylic acid and a C2 to C12 aliphatic diol;
- and
- b. spinning the polymer composition to form fibers, such that the highest temperature applied to the polymer during spinning is in the range of from about 210 to about 265° C.
