Elastic covering yarn consists of a drawn elasthane filament yarn, covered with polyamide. polyester or viscose filament yarn, as core. The core may be covered with cellulose, cellulose/ polyester, cellulose/polyacrylonitrile, wool, regenerated cellulose fibres, or mixts. with polyester or polyacrylonitrile. Pref., the elasthane filament yarn is 30-200dtex, and the covering material is 15-90dtex with a number range of Nm40-Nm10 (Nm30-Nm12). In partic, 45dtex, 80dtex, or 160dtex elasthane filament yarns are covered with 22dtex, 33dtex, 50dtex, 67dtex, or 78dtex polyamide or polyester filament yarns.
