Abstract
A low shrinkage, dimensionally stable, polyester industrial fiber is produced by a process which involves conditions of continuously spinning and drawing filaments wherein the filaments are passed through a steam impinging draw point localizing jet (25) at a temperature of about 460.degree. C. to 580.degree. C. to thereby heat the filaments substantially immediately above their second order transition temperature. The low shrinkage polyester fibers are particularly useful in the preparation of industrial products, including industrial belts, conveyor belts, and reinforced elastomeric structures.
