Abstract
A method of making a sheared wool, deep pile fabric that closely resembles natural sheepskin fleece that includes forming a length of wool pile fabric having natural wool fibers on one side and a scrim on an opposing side and finishing the wool pile fabric as natural shearling. The finishing process includes polishing the wool fiber side of the pile fabric by guiding the length of pile fabric over one or more heated first polishing rolls, applying a sheepskin conditioning solution to the wool fiber side of the pile fabric, further polishing the wool fiber side of the pile fabric by guiding the fabric a plurality of times over one or more second heated polishing rolls, and cutting the wool fibers to a designated length.
