Embodiment Construction

[0025] The "upstream" mentioned in the present invention refers to the upstream along the yarn moving direction, and the "downstream" refers to the downstream along the yarn moving direction.

[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] Please refer to figure 1 , in the spinning process, the roving 1 enters the rear nip of the rear roller 3 and the rear upper top roller 4 through the yarn guide rod 2, enters the middle nip of the middle roller 5 and the middle upper iron roller 6 through the rear drafting area, and then passes through The front drafting zone enters the front nip of the front roller 7 and the front top roller 8, and is twisted into yarn at the front nip, then contacts with the wet supply device 9, passes through the yarn guide hook 10, and is wound to the bobbin 11 on.

[0028] Such as Figure 2-4In one embodiment shown, the moisture supply device 9 of the pr...

Abstract

The invention provides a ring spinning frame employing a single-spindle atomization wetting device to reduce hair. The ring spinning frame comprises a front roller, a front top roller corresponding to the front roller, and a yarn guide hook which moves vertically up and down in a spinning process. A front jaw is formed between the front roller and the front top roller. The ring spinning frame is characterized in that a wetting device is arranged in a yarn guide section between the front jaw and the yarn guide hook and comprises a friction ring made of wear-resistant material with a low friction coefficient; the friction ring comes into contact with yarn from under; the whole wetting device only comes into contact with yarn via the friction ring. The ring spinning frame with the wetting device has the advantages that the amount of harmful hair of spun yarn can be greatly reduced, fiber utilization rate is increased and yarn properties are improved as a whole. The friction ring is used for guiding yarn, so that it is guaranteed that the included angle of yarn from a twisting triangular space does not change, the length of a surrounding arc formed on the surface of the front roller by yarn is reduced and the quality of yarn is further improved.

Description

technical field [0001] The invention relates to a ring spinning yarn forming device, in particular to a device for reducing hairiness in yarn. Background technique [0002] The harmful hairiness of the yarn causes the yarn slivers to stick together during the weaving process, causing the opening to be unclear, and it is also easy to cause end breakage to form crosspiece weaving defects, which seriously affects production efficiency, and the hairiness will also form neps, resulting in differences in subsequent dyeing, and also It will cause flying flowers and seriously affect the working environment. Therefore, it is of great significance to improve the hairiness and further increase the fiber utilization rate through technical processes, so as to improve the yarn performance as a whole. [0003] Ring spinning has always been an important spinning method that occupies more than 80% of the entire spinning market. In the process of ring spinning, the front roller jaws hold th...
