20090211219 | Device and method for treating filament yarn and fancy knotted, migrated, and false-twist yarn - The invention relates to a device for treating filament yarn by means of air nozzles comprising at least two injector/cover plates that can be clamped together, and at least one air supply channel. Said injector/cover plates form a yarn treatment chamber in the assembled state. According to the invention, the yarn treatment chamber is formed between the injector/cover plates that can be clamped together, in the longitudinal direction of the plates, and the air nozzle is embodied as an open nozzle comprising a threading slit and an individual air supply channel for the yarn channel in the injector/cover plates. The invention has two decisive advantages. The shape of the injector/cover plates is limited to the inherent core functions, namely a yarn channel formed in the plates, the threading slit, and the individual air supply channel for the yarn channel in the plate. The miniaturisation of the injector/cover plates significantly simplifies the production problems. | 08-27-2009 |
20100024376 | Method and apparatus for manufacturing slalom false twisting on ring yarn - In a process for manufacturing a singles ring yarn, a method and apparatus is invented which utilizes double belts as a false twist device and incorporates it in the conventional ring spinning machine for producing a singles ring yarn. In this invention, a double-belts is applied thus two twisting points, instead of one twisting point, are adopted for the yarn false twisting to improve the false twist efficiency. Accordingly, a ratio of the velocity of the belt to the delivery speed of the yarn is controlled and the wrapping angle of the yarn on the belts is adjusted in order to obtain the desired property of the final singles ring yarn. The said invention can enhance the strength of fiber strand at the spinning triangle and thus ensure the yarns spun in a normal condition at low twist multipliers, which is unable to be obtained by the conventional ring spinning machine. The method produces yarns with good strength, less hairiness and lower yarn residual torque at low twist level and endows the resultant fabric with softer handle, low spirality as well as clear and smooth surface appearance. The method and apparatus has the advantages of easy yarn piecing-up and doffing process, low spinning end-breakage when using ordinary raw materials and low cost of investment and maintenance, which not only is able to meet the commercial requirements of the large-scale production in the textile industry but also possesses a high false twist efficiency. | 02-04-2010 |

20110131944 | FALSE-TWIST BELT - Two false-twist belts are each entrained about crowned pulleys. The belts are arranged so that their outer-facing surfaces cross one another with one belt pressed against the other. Yarn is passed between these false-twist belts and twisted. The bending rigidity in the lateral direction of the false-twist belts is set to a value in which the outer-facing surfaces of the false-twist belts are rounded into a convex curvature at the position where the belts are pressed against each other. | 06-09-2011 |

20150128555 | Combined frictional false twisting device for ring spinning frame - A frictional false twister is disclosed. The twister has a plurality of rotating friction plates located between the nip of the front rollers and the yarn guide. The friction plates are staggeringly arranged for rubbing a twisted yarn. The spinning direction of the twisted yarn is opposite to the rotating direction of the friction plates. Through the action of the frictional false twister, the twist of the yarn between the false twisting device to the front nip can be increased, shortening the twisting triangle height, and increasing the spinning strength. As the yarn and the outer surface of the friction plate make relative sliding and rubbing, the friction damping force correspondingly reduces the spinning tension in the twisting triangle. | 05-14-2015 |
