National Spinning Co., Inc. is a leading USA-based supplier of dyed and raw white (ecru) short staple and long staple spun yarns. In addition, we supply dyed filament yarns. Founded in 1921 with roots in worsted wool spinning and dyeing, we came to be particularly well-known for high quality acrylic yarns in the second half of the 20th century. In recent years, we have broadened our US operations and expanded our base of internationally-sourced raw materials. Currently, we offer a diverse product line of specialty and commodity yarns for domestic and international markets.
