Abstract
A blend of low shrinkage polyester fibers and high shrinkage polyester fibers is described. In particular, the blend includes high shrinkage PET copolymers having boiling water shrinkages from 6 to 11 percent and low shrinkage PET copolymer fibers having a shrinkage of less than 3 percent. Textured carpets and rugs made from the blend consistently have better initial tuft end point definition and, in most cases, better bulk than corresponding polyester carpets made from conventional polyester fibers.
