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. Saxony carpets made from the blend consistently have better initial tuft end point definition and, in most cases, better bulk than corresponding saxony polyester carpets made from conventional polyester fibers.
