    摘要: There is disclosed a variable denier, multifilament yarn having a slub yarn plied with a carrier yarn and displaying high weaving performance. The yarn is characterized by a certain slub size distribution, a certain minimum number of slubs, a specified maximum number of large slubs, less than one tight spot per meter and a coherency factor of from about 4-14, said coherency factor increasing as the number of large slubs increases. A process for making the yarn is also disclosed and includes the features of feeding both feed yarn and carrier yarn to a supply jet, the feed yarn being overfed while the carrier yarn is maintained under zero net overfeed, forwarding the carrier yarn to a slub jet and forwarding the feed yarn to a foraminous surface where slubs are created and thereafter combining both yarns and passing them sequentially through a slub jet, at least one interlacing jet and, optionally, a torque jet.
