Abstract
A metal covered composite yarn, particularly designed for ornamental purposes, comprises a textile non-metal core formed by a plurality of substantially parallel ultra-thin filaments, a metal cover formed by a relatively thin metal foil ribbon which is spirally wound around the core. The filaments have a substantially lapped or mirror surface finish to minimize resistance to sliding between adjacent filaments and provide a considerable core compliance, and a high yarn softness and flexibility.
