    摘要: High shrinkage polyester fibers having good strength and uniform dyeability are disclosed, along with a method of producing the high shrinkage polyester fibers, by drawing a feeder yarn having a birefringence (n) of at least 0.0175 at a temperature below the glass transition temperature for the polyester and with carefully controlled draw ratios.
