Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to provide a wrapping type that enables the noil fiber strands to be directly twisted into yarn by the steel ring traveler, so that the noil fibers can be spun normally and improve the utilization rate of noil. The compact spinning method and its device solve the problem that the traditional spinning technology can only spin low-count yarns, and because the wrapping effect of short fiber noil is poor, the yarn strength is low, which makes it less effective for short fiber noil. The problem of low reuse rate

Abstract

The invention discloses a wrapped-type compact spinning device which comprises a front roller, a middle roller, a back roller, a spinning frame twisting mechanism, an output roller, an annular winding device and a filament unwinding device. The front roller, the middle roller and the back roller are sequentially arranged from front to back. The annular winding device is arranged between the front roller and the output roller, and comprises a hollow fixed shaft. The two ends of the hollow fixed shaft are provided with a filament packaging mechanism and a winding mechanism respectively. The filament packaging mechanism is composed of a filament package and a filament package fixing part installed on the hollow fixed shaft. The winding mechanism is composed of a filament winding part installed on the hollow fixed shaft, and a tension device. The filament winding part is driven in a unified mode by a winding conveying belt connected with the filament winding part. The filament unwinding device is the same as the spinning frame twisting mechanism in size structure, and the filament unwinding device and the spinning frame twisting mechanism are installed at the bottom of a spinning frame in a side-by-side mode from interior to exterior. The wrapped-type compact spinning device has the advantages that noil fiber strips can be directly twisted by steel collars and steel wire rings to form yarn, and the noil utilization rate is improved.

Description

technical field [0001] The invention relates to a wrapping compact spinning method and a device thereof, in particular to a spinning method and device based on traditional ring spinning technology using filaments to wind ultra-short fiber strands, and belongs to the field of textile technology. Background technique [0002] After textile fibers pass through multiple spinning processes, a large amount of noil will be generated. The linters and impurities separated from the opener, carding machine and combing machine include broken seeds, ground flowers, car belly flowers, cut flowers and combed noil, etc. These impurities are generally not used for normal spinning . Domestically, fibers less than 16mm are generally considered as short staples, while internationally, cotton fibers less than 12.7mm (0.5 inches) are considered short staples. AFis, HVI and PREMIER fiber testers all define the linters below 12.7mm. In order to improve the reuse of short fiber noil, many cotton ...
