Abstract
A method for forming a metallic fabric includes forming a composite yarn having a metallic wire core, and a cover yarn including a fluid-soluble strand such as co-nylon or polylactic acid. The composite yarn can be knitted into an intermediate fabric product. The soluble element is dissolved to leave a use fabric suitable for other processing, such as coating with materials such as latex. The non-fluid-soluble strand may be either a single strand or multi-filaments of steel wire.

A method of producing a metallic fabric, comprising the steps of:
- (a) providing a composite yarn comprising:
- (i) a metallic wire,
- (ii) a fluid-soluble strand,
- (iii) an elastomeric strand, and
- (iv) wherein the composite yarn includes a core and a cover wrapped around the core, the core comprising the fluid-soluble strand;
- (b) forming the composite yarn into an intermediate fabric;
- and
- (c) dissolving the fluid-soluble strand, thereby forming a use fabric comprised of the remaining metallic wire.
