Abstract
Disclosed are novel yarns comprised of at least two, and preferably three, strands of filaments, being twisted about the other strands in random "s" and "z" directions in variant degress with filaments of each strand being interlaced together to produce a cohesive commingled yarn. The individual strands although interlaced with the other strands maintain substantial integrity in the commingled yarn and preferably have different dye affinities. Methods of manufacturing the novel yarns are also disclosed.
Claims21
The method of interlacing a plurality of strands into a commingled yarn comprising the steps of combining the plurality of strands in parallel from a supply source, then twisting the individual strands within the combination in random "s" and "z" directions in variant degrees about each other while simultaneously interlacing filaments of an each strand with filaments of adjacent strand to entrap the random twists in the commingled single yarn while maintaining substantial integrity of each strand, and thereafter winding into a package.
The method of making a novelty yarn composed of at least three strands of synthetic linear polymeric filaments comprising the steps of combining the strands in parallel from their sources of supply, twisting the individual strands about each other along their lengths in random "s" and "z" directions of variant degrees, including no twist, while simultaneously interlacing filaments of each strand with filaments of adjacent strands to entrap the random twists in a cohesive commingled yarn.
A method of interlacing a plurality of continuous strands of yarn filaments into a single commingled yarn comprising the steps of continuously feeding said strands under tension to a confined yarn interlacing zone, injecting a gas under pressure in a turbulent manner into said confined yarn interlacing zone to agitate and twist the strands about each other along their lengths in random "s" and "z" directions of variant degrees, including no twist, while simultaneously interlacing filaments of each strand with filaments of adjacent strands to entrap the random twists in a cohesive commingled yarn.
A novel yarn comprised of at least two strands of filaments twisted in random "s" and "z" directions in variant degrees of twist along their lengths, including sections of no twist, and having filaments of each strand simulaneously interlaced with filaments of adjacent strands to entrap the random twists in a cohesive, commingled yarn.
A novel yarn comprised of three strands of filaments which have been mechanically crimped and then twisted in random "s" and "z" directions in variant degrees of twist along their lengths, including sections of no twist, and having filaments of each strand interlaced with filaments of adjacent strands to entrap the random twists in a cohesive, commingled yarn, the filaments of each strand having different dye affinities.
