  • Publication number: 20080299855
    Abstract: It is an object of the present invention to provide a core yarn capable of spinning the higher-grade yarn having the higher yarn count from specified lower-grade raw material and the core yarn makes its texture-feeling, strength and extension rate equal to that of natural fibers. The core yarn is formed of spun yarn including the core formed of filament yarn and the sheath formed of staple, and the filament yarn is a monofilament false twist textured yarn.

  • Patent number: 5107671
    Abstract: A multi-ply spun yarn having a self-converging property and a method for producing it. In the method wherein fiber is drafted first and introduced into an air jetting twisting device, and then yarns spun out by the twisting device are joined together by a guide member and taken up onto a take-up device, the twisted yarns are joined together after separated by a separating guide.

  • Patent number: 4497167
    Abstract: A spun yarn is manufactured from a sliver through an action of a first fluid swirling nozzle and a second fluid swirling nozzle capable of swirling a fluid in a direction opposite to the direction of swirling of a fluid in the first fluid swirling nozzle. Fibers detached from a sliver between a front roller assembly and a first fluid swirling nozzle are caused to wind positively around the twisted fibers during spinning operation.

  • Patent number: 4457130
    Abstract: An air nozzle for spinning yarn is positioned adjacent a pair of drafting rollers. The space between a cap covering the nozzle and the nozzle itself forms a tank for the air to be jetted through the nozzle. A tapered throttle located behind the nozzle reduces resistance to air exiting from the jetting ports.

  • Patent number: 4387487
    Abstract: A high draft apparatus in a spinning machine for forming a spun yarn from a roving or sliver. The draft apparatus comprises back rollers, apron-provided middle rollers and front rollers and a gripping and a pressing means for a sliver disposed on the front end portion of the apron so that the arrangement of fibers in the drafted sliver is regulated and a high draft ratio can be attained.
