Recycled poly (ethylene terephthalate) (r-pet) used in blends with a fiber grade material (f-pet) is investigated. As-spun fibers of r-pet, f-pet, and r/f-pet blends are made at winding speeds ranging from 1000 to 4000 m/min (mpm), with subsequent drawing in the range of 1.6 to 4.0×. Spinning and drawing behaviors of the fibers are analyzed using orientation (birefringence), boil-off shrinkage, calorimetric (dsc), and mechanical measurements. The fully oriented yarns from the r-pet show a tensile strength of 70% of the fiber grade, with 3.2 g/d (r-pet) to 4.6 g/d (f-pet), which still meets and surpasses minimum industrial requirements. The dsc study of these materials indicates that the decreased crystallinity of the r-pet may be the main cause for the decreased tensile strength of the product.

ABSTRACTIn this work, we present the synthesis and characterization of a new series of wholly-aromatic copolyesters derived from the condensation of various weight fractions of 4,4'-(o- phenylenedioxy)dibenzoic acid (OPDB) and substituted terephthalic acid (BTA) with 2-phenylhydroquinone (PHQ). The Higashi method, involving tosyl chloride and pyridine as solvent, was employed to yield polymer with significant molecular weight. These polymers are intended to enable accessible clearing transition and to control the balance of stiffness and toughness in melt-spun fibers systematically. We report the synthetic details along with characterization of quiescent phase behavior and morphology.
