Abstract

Described is wet-spun plural-end elastane yarn having a yarn linear density of up to 2500 dtex, high surface luster and a ribbony cross section and formed from bonded-together individual filaments having an oval to circularly round cross section, the width of the elastane yarn in cross section being at least four times the thickness of the elastane yarn.
