Technical Field

The invention relates to the technical field of spinning, in particular to a spinning method and a spinning device for transversely and movably regulating a fiber yarn forming structure on a ring spinning frame and yarn.

Background

The spinning technology of the short fiber is to process disordered and scattered fiber raw materials into linear aggregates with certain trend, cohesion and linear density through a series of mechanical actions, and provides powerful guarantee for the fiber raw materials to be made into sheet-shaped or three-dimensional fabrics.

The ring spinning technology belongs to holding end spinning, is widely applied due to strong adaptability of raw materials and wide production variety range, but also has the defects of more yarn hairiness, insufficient strength, poor hand feeling, high difficulty of quality control, low efficiency and the like. When the yarn is wound by the bobbin, the steel wire ring is driven to rotate around the steel collar, the sliver is twisted, so that the fibers inside and outside the strand can be in self-balance, the external fibers are transferred inwards, the internal fibers are transferred outwards and are mutually clasped to form continuous yarn, and a special yarn structure is formed. The unidirectional twist back cohesion is a special structure of ring spinning yarns, and a fiber continuous body with enough strength is formed by twisting cohesion of fiber bundles. However, the drawback of the unidirectional twist looping is that the residual torque of the internal fiber and the exposure of the fiber hairiness on the surface layer are caused during twisting, so that the ring single yarn with special fiber structure characteristics, such as low torque, low twist, high strength, less hairiness and good evenness, cannot be realized.

Aiming at overcoming the problems of much filoplume and insufficient strength of resultant yarn, the compact spinning technology is developed rapidly in recent years, and the compact spinning technology is a novel spinning method for reducing or eliminating a twisting triangular area by gathering fiber strands in a ring spinning triangular area, effectively controlling the twisting of fibers at the edge of the strands to form yarn, greatly reducing filoplume of ring yarn and forming the yarn with a fiber compact gathering cohesive structure. At present, negative pressure airflow or mechanical grooves 2 modes are mainly adopted to gather the fiber bars in the ring spinning triangular area, wherein the negative pressure airflow gathering technology is developed well, and common CompACT spinning instruments in the market comprise ComACT 3 of Zinser company, K44(Com4) of Rieter company, Elite of Suessen company and the like; the mechanical groove type compact spinning device has poor spinning stability, and is not popularized and used on a large scale at present. Compared with the common ring yarn, the compact spinning yarn has obvious effects on the aspects of yarn strength, wear resistance improvement, hairiness reduction and the like, but also causes new problems of compact yarn, hard handfeel of the prepared fabric, high production energy consumption and the like. Aiming at the problem of hard hand feeling of the conventional compact spinning, some researchers develop novel methods for removing feather and gathering, changing the apparent structure of the yarn and not deteriorating the hand feeling of the finished yarn. For example, chinese patent No. CN201410671777.0, published japanese patent No. 2015.2.4, entitled bundle of fibers in ring spinning processing, provides a bundle of fibers removing device with simple structure and no additional energy consumption, which uses a rotary sheave to gather and reshape a triangular region to dynamically capture and gather fibers on the surface of a yarn formed by twisting a sufficient inner and outer transfer motion, thereby greatly improving the quality of finished yarn, but in actual production, the fibers will wrap the rotary sheave to cause breakage. Chinese patent No. CN1995510A, published by the name of 2007.7.11, discloses an ironing spinning method for improving yarn performance, and performs heat and humidity treatment on fibers in the spinning process, so that the fiber rigidity is reduced, the fibers are fully transferred inside and outside, and the generation of yarn hairiness is reduced. However, the devices are inconvenient to process and install, additional energy consumption is needed, certain potential safety hazards exist, and the method has no obvious effect on the non-heat-sensitive fibers. Meanwhile, the patents only can cohere single gathered fibers to promote the tight wrapping of the finished yarn, and although the hand feeling of the finished yarn is not deteriorated, the residual torque in the fibers cannot be balanced, the stress distribution cannot be adjusted, and the yarn is softened.

Besides the spinning mode of regulating and controlling yarn fiber aggregation and producing the yarn with the fiber compact cohesion structure, the spinning mode of regulating and controlling the yarn fiber arrangement structure to promote the torque in the finished yarn to be balanced and producing the yarn with the low-torque structure is also an important way for improving the performance of ring spinning finished yarn and producing the yarn with a novel structure. Aiming at overcoming the problems of large residual torque inside the finished yarn and poor yarn hand feeling, the low-torque yarn developed by the Touchi Mingzhou of hong Kong university has excellent physical performance, and the principle is that a high-speed false twister is arranged at a yarn guide hook of ring spinning, the twist of a spinning section is increased, the adjustment of a fiber non-coaxial special-shaped spiral line structure is realized, and the control of local reversal of a fiber segment is realized, so that the twist and the torque of the ring spinning can be reduced, soft, low-twist and low-shrinkage high-end spun yarn is spun, high-end textiles are developed, and the potential value of the low-torque low-twist low-shrinkage low-twist low-shrinkage low. For example, chinese patent No. CN02118588.3, published japanese patent No. 2008.10.15, entitled method and apparatus for processing single-strand torqueless ring yarn, the present application provides a brand-new method for processing single-strand torqueless yarn, aiming at the problem of large residual torque of ring spun yarn, and false twisting is generated by a false twister, so that the twist direction of sub-fiber bundle of yarn is opposite to that of the single-strand yarn synthesized by the sub-fiber bundle, thereby balancing the residual torque inside the yarn, and simultaneously, low twist yarn which cannot be normally processed by the conventional ring spinning machine can be processed; the invention relates to a method and a device for producing bending false twist on a ring spun yarn, wherein the Chinese patent number is CN101643948A, the publication number is 2010.2.10, and the invention and creation name is that two belts are used as false twist equipment to enable the yarn to have two twisting points to carry out false twist during the spinning process; chinese patent No. CN200510004306.5, published Japanese 2011.4.6, invented and created a processing method and equipment of low-twist single-strand ring spindle yarn, which adopts spindle to drive friction disk to rotate to make false twisting so as to implement that the single-strand yarn has controllable residual torque. However, the method for producing the low-torque yarn by the false twister has the advantages that the acting force of the false twister on the yarn is vertical to the moving direction of the yarn, so that the yarn evenness is greatly influenced, the technical problems of low internal and external transfer degree of the original fiber, poor fiber cohesion, low resultant yarn strength, high resultant yarn hairiness and the like in the structure of the yarn produced by the method can not be fundamentally solved, and meanwhile, the spinning process is complex, the mechanism cost is high, and the operation is inconvenient.

Generally, yarns with inner and outer layered structures, which gather surface fibers to form an apparent compact structure, reduce hairiness of ring yarns, adjust the arrangement state of the fibers in the yarns and release residual torque in the yarns, cannot be realized by unidirectional ring twisting, and a spinning method for realizing the difference of the inner and outer layered structures of the yarns needs to be respectively processed in a plurality of processes. In order to solve the problem, researchers respectively research a plurality of methods for realizing layered control of fiber yarn formation. For example, chinese patent No. CN 201410105223.4, published japanese patent No. 2014.3.20, entitled method and apparatus for processing low-hairiness low-torque ring yarn, invented and created by the present invention, utilizes a rotating airflow ejected from a nozzle to apply a reverse twist to the yarn, and impels the surface layer yarn to partially turn over and wrap, thereby spinning low-hairiness low-torque yarn, but its energy consumption is high, operation accuracy is high, mechanism is complex, and it is difficult to realize mass production. In addition, Liu Coshuai et al, in journal of the science of textile (journal of textile research), Vol.39, No.2, 2018, disclose a serial semi-open type multiple gathering spinning method, which utilizes the pre-gathering effect to reduce the width of a twisting triangular area, gathers sheave to remold the triangular area, gathers and twists the surface fibers of fiber strand by twisting disc, realizes the tight winding of the surface fibers, and realizes the structural characteristics of tight outside and soft inside of the finished yarn. The method can manufacture high-quality yarn with fully transferred internal fibers and tightly gathered external fibers, but the spinning method needs three groups of spinning devices to be used in series, the operation is complex, and simultaneously, the yarn breakage is easy to occur in the spinning process, thereby affecting the production efficiency.
