Abstract
A method of making a sheared wool, deep pile fabric that closely resembles natural sheepskin fleece, that includes forming a yarn made from wool fibers and simultaneously knitting the yarn and a scrim together, where the yarn is attached to and extends from the scrim to form a length of wool pile fabric having natural wool fibers on one side and the scrim on an opposing side. The method includes finishing the wool pile fabric as natural sheepskin by polishing the wool fiber side of the pile fabric by guiding the length of pile fabric over plural heated polishing rolls, where at least two of the plural heated polishing rolls rotate in opposite directions, and cutting the wool fibers to a designated length.
