Composite front ring spinning method

Abstract

The invention relates to a composite front ring spinning method and belongs to the technical field of textile processing. A front filament feeding device is arranged at the front end of a cradle corresponding to every extension mechanism of a ring spinning frame; a filament F1 and a filament F2 unwound are mounted on filament cylinders, fed into the front filament feeding devices via a filament guiding device and directly fed into a ring spinning resultant yarn area to be converged and twisted with short fiber fringes output from front roller jaws, and the composited yarn formed by twisting is finally wound on a yarn tube after passing a yarn guiding hook, a steel collar and a bead ring. The composite front ring spinning method has the advantages that generated abrasion to rubber rolls and rollers when the filaments are fed via the rear ends of the front roller jaws of the ring spinning frame is eliminated, multidirectional and stereoscopic embracing, twisting and spinning of the filaments and the short fiber fringes are realized, and in practical production, cost is low, harmful substances and potential safety hazard are avoided, and equipment is simple to transform and convenient to operate and use.

Description

technical field [0001] The invention relates to a method of placing filament or spun yarn in front of the nip of the front roller on a ring spinning frame, and feeding it into the composite spinning area of ​​the ring spindle for composite spinning, which belongs to textile processing technology field. Background technique [0002] With the technological progress of textile materials and people's higher and higher demand for clothing fabric styles, the requirements for spinning technology are also getting higher and higher, and various spinning methods emerge in endlessly, such as sirofil spinning, siro spinning , compact spinning, cable spinning, core spinning, embedded spinning, etc. These spinning methods have greatly enriched the spinning processing methods and significantly improved the quality of the finished thread. Among them, the spinning methods such as sirofill spinning, insert spinning and core spinning involve short fibers and filaments, which belong to the cat...

Problems solved by technology

[0004] In view of the current filament composite spinning process, the filament is fed from the rear end of the front roller nip of the ring spinning machine to the front roller, which will cause wear and tear on the rubber rollers and rollers, and it is impossible to realize the spatial position of the filament and short fiber. For the technical problem of multi-directional and three-dimensional wrapping and twisting, the present invention provides a method for avoiding the nip of the front roller and directly feeding the filament into the yarn forming area of ​​the ring-spindle composite spinning, so as to realize the Ring-spinning composite spinning method of multi-directional three-dimensional twisting of strands into yarn
