ABSTRACT:
A low shrinkage polyester fiber is produced by melt-spinning a polyester polymer under conditions of substantially simultaneous spinning, drawing, and heat treating, using carefully controlled conditions whereby the fiber has uniform properties of breaking strength in grams per denier of at least 7.0, elongation at break in percent of 18 to 30, and a residual thermal shrinkage measured in an oven at 350.degree. F. for one minute of lower than 3 percent. The low shrinkage polyester fibers are particularly useful in the preparation of reinforced elastomeric structures.
