Abstract
The present invention is directed to a fiber blend useful in the manufacture of carpet yarn used for pile in carpet construction. The blend includes, by weight based on the weight of the total blend, about 40% to about 70% normally crimped fibers, about 5% to about 50% crimpset fibers and about 4% to about 40% high shrinkage fibers having a shrinkage value of from about 15% to about 50%. Carpets including pile yarn formed from the blends of the present invention exhibit superior resistance to watermarking as well as other desirable characteristics.
