A plurality of heavy denier thermoplastic monofilaments is gathered together and continuously wrapped with a flexible wrapper yarn. The wrapped bundle is fed into a stuffer crimper to form a multiplicity of texturized bends. The product is a stiff, pliable texturized yarn and the nomofilaments in the wrapped bundle have a multiplicity of heat-set bends repeating lengthwise along the lengths of the monofilaments.

Monofilament-wrap texturizing method and product

This invention discloses a yarn, and method and apparatus for making it, composed of a core component having yarn strength wrapped clockwise and counter-clockwise by wrapper components, wherein the core has a sinuous configuration and contains a greater length per unit of yarn length than the wrapper components. Optionally, the core component may be a newly texturized multi-filament yarn, wrapped according to this invention before being subjected to significant tension, thereby preserving much of the bulk that would otherwise be lost in winding or other tensioning of the texturized core in unwrapped condition.
