Problems solved by technology

Can not meet the spinning process requirements at the same time, resulting in a decline in yarn quality, this technical problem has not been resolved
[0005] 2. The traditional ring spinning machine has three-dimensional twisting triangle defect
Among them, the amount of circular hairiness produced by the adhesion of rubber rollers is relatively large, and the circular hairiness produced by roller burrs is relatively small, but it is also very harmful, and it is easy to cause winding rollers and increase the rate of spinning end breaks

Embodiment Construction

[0036] The present invention adopts the imported spinning frame Zinser 319, the spinning count is Nm36, and the trial spinning raw material is semi-combed wool.

[0037] see Figure 4 It is the structural representation of the semi-compact spinning device of the present invention and Figure 5 for Figure 4 As shown in the A-A sectional view of the ring spinning semi-compact spinning method, the roving is drafted and twisted by the front bottom roller nip of the original ring spinning machine, and the front rubber roller and the front bottom roller of the original ring spinning machine A draft zone and a weak twist zone are formed at the roller, and a semi-compact spinning device that can adjust the length of the traction zone and the length of the weak twist zone is installed downstream of the original front rubber roller 2 and the original front bottom roller 3 of the original ring spinning machine. The described semi-compact spinning device comprises a yarn drawing roller...

Abstract

The invention relates to a ring-spinning semi-compact spinning process. Rough yarn is drawn and twisted by a front bottom roller nip of an original ring-spinning machine; a semi-compact spinning device which can regulate the length of a drawing area and the length of a weak twisting area is arranged at the downstream of a front rubber roll and a front bottom roller of the original ring-spinning machine; wherein, the semi-compact spinning device comprises a doffing roller, a doffing rubber roll, aprons and a device base; the aprons are sleeved at the outside of the front bottom roller of the original ring-spinning machine and the doffing rubber roll of the semi-compact spinning device; the doffing roller and the doffing rubber roll are arranged on the device base; the device base is fixed with a rack of the original ring-spinning machine, and the rough yarn is transmitted to a doffing roller nip after being drawn by the front bottom roller nip of the original ring-spinning machine and drawn out from the position between the doffing roller and the doffing rubber roll, thereby preparing twisted yarn. The ring-spinning semi-compact spinning process has the advantages that the spun yarn evenness is improved and the hairiness is greatly reduced, thereby greatly reducing the defects of fabric neps and color neps and significantly improving the anti-pilling grade of fabric.

Description

technical field [0001] The present invention relates to the technical transformation of traditional ring spinning machines, including domestic models and imported models, and especially relates to a ring spinning semi-compact spinning process, which can be used to spin wool worsted and wool semi-compact spinning through the semi-compact spinning technology. Worsted, woolen and other semi-compact high-quality yarns. Background technique [0002] Hairiness is an important quality index of yarn, which directly affects the quality of weaving and product grade. Hairiness is generally divided into forward hairiness, reverse hairiness, circular hairiness and planktonic hairiness, etc. Forward hairiness and reverse hairiness are not easy to be pulled out or elongated, and planktonic hairiness will fall automatically. The circle hairiness refers to the hairiness spirally wrapped on the surface of the yarn body. After the circle hairiness rubs against the machine parts, the spiral ci...
