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.

A metal covered composite yarn, particularly for ornamental purposes, comprising:
- a textile non-metallic 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 said core;
- wherein said filaments have a substantially lapped or mirror surface finish to minimize sliding resistance between adjacent filaments, thereby providing a considerable core compliance and a high yarn softness and flexibility.
A method of manufacturing a metal covered composite yarn, comprising:
- providing a plurality of non-metallic extremely thin filaments;
- gathering said filaments to form a bundle defining a textile core;
- providing a relatively thin metal foil strip;
- and
- spirally winding said strip around said core to form a metal cover;
- wherein the surface of said filaments is lapped or polished to minimize resistance to sliding between adjacent filaments not directly in contact with said metal cover.
A metal covered composite yarn, comprising:
- a non-metallic core formed by a plurality of substantially parallel filaments;
- a metal cover formed by a relatively thin metal foil, which is wound around said core;
- wherein said filaments have a substantially smooth surface to minimize sliding resistance between adjacent filaments.
A method of manufacturing a metal covered composite yarn, comprising:
- providing a plurality of non-metallic filaments;
- gathering said filaments to form a bundle defining a textile core;
- providing a relatively thin metal foil ribbon;
- and
- spirally winding said ribbon around said core to form a metal cover;
- wherein the surface of said filaments is substantially smooth to minimize sliding resistance between adjacent filaments not directly in contact with said metal cover.
