Abstract
A carpet yarn is a plurality of fibers spun from a multiconstituent polymer alloy composed of 60 wt. % or more of nylon 6; up to about 37 wt. % of a stereoregular polyolefin having a melt flow index of from about 2 to about 100; and 3-37 wt. % of a polyolefin that is at least partially modified by one or more type of polar monomer. Upon steam heatsetting at about 124.degree. C., the yarn shrinks less than about 20%.
