Wrapped and Covered Yarn Systems
topic
Yarn wrapping machines wind one or more effect yarns in helical wraps around a core yarn at defined turns per metre through a spindle rotating around the stationary core, with single-wrap providing decorative metallic or contrasting colour effects and double-wrap providing balanced twist coverage used for metallic decorative yarns, elastic covered yarns, and electrically conductive metal wire wrapped yarns.
Role
Produces composite yarn structures combining distinct core and wrapper fibre properties in single yarn constructions used in decorative metallic fashion yarns, wrapped elastic yarns for swimwear and hosiery, and conductive metal wire wrapped yarns for e-textile applications where the core-wrapper structure independently optimises each component contribution to the composite yarn functional and aesthetic properties.
