Title: BIO-BASED MEG AND POLYESTER FIBER COMPOSITIONS AND METHODS OF MAKING THE SAME
Abstract:
Disclosed are bio-based polyester fibers, particularly a PET fibers, and a method of making the same by: contacting a bio-based MEG composition with a diacid composition to form a polyester composition; and spinning and/or drawing the resulting polyester composition into a fiber; wherein the bio-based MEG composition comprises: a) monoethylene glycol (MEG); and b) from about 1 ppm to about 5000 ppm of at least one C3-C12 1,2-diol, wherein the C3-C12 1, 2-diol is linear, branched, or cyclic.
