An elastane multifilament yarn havig two to six individual filaments which, when being unwound from a bobbin, is splittable into individual filaments, is produced by a process wherein multihole spinning jets are deployed in the spinning head of a conventional dry spinning apparatus, laminarizing the spinning gas flow to prevent entanglement of the individual filaments and passing the resulting yarn through a thread guide with one opening per individual filament.

Splittable elastane yarns

An improved dry spinning process for manufacturing splittable elastane multifilament yarns wherein the coalescence of individual filaments is prevented, through the use of multihole spinning jets, laminarizing gas flow and thread guides having one opening per individual fiber.
