Abstract
Improved yarn for manufacturing artificial fur, having underfur and guard hairs. The guard hairs have a multiplicity of staple fibers having tapered ends. The underfur fibers are shorter and of less denier. The guard hairs and underfur fibers are relatively longitudinally slidable to separate at least some of the fibers from others of the fibers. Temporary binding means may be connected to maintain the respective fibers in continuity and resistant to longitudinal sliding separation during one or more fabrication operations. Inactivation of the binding means breaks the continuity of said pile fibers whereupon at least some of the fibers may be longitudinally slidingly separated without being broken.
