Causes and Solutions of Self-winding Cylinder Yarn Affecting the Broken Head of the Whole Meridian
Release time:

The broken end of the warping machine is the broken end of the yarn during the normal winding of the warping machine.
The index for assessing the broken ends of the warping is "the number of broken ends of one hundred and ten thousand meters", that is, the number of broken ends of one warp yarn within a length of one million meters. Due to different fabric structures, when the unwinding process of the bobbin yarn on the warping machine is particularly interrupted, it will not only affect the efficiency of the warping machine, increase the workload of the stopper, but also increase the defect surface and have adverse effects on the fabric, spinning mills that sell yarn are likely to lose orders as a result.
It can be seen that the problem of whole and broken ends is very important. Common problems such as adhesion broken ends, ring-off broken ends, random layer or wire-back broken ends, and irregular broken ends need to be solved according to the remedy to the case.
1. adhesion broken head
The problem of adhesion breakage is the breakage caused by entanglement when the yarn is unwound, which is usually broken when the diameter of the bobbin is relatively large. The reason is that the bobbin yarn tension is large and the bobbin winding is too tight. In view of the fact that the large yarn of the bobbin is stuck and broken, part of the reason is that the weight of the bobbin gradually increases with the increase of the diameter of the bobbin during the winding process. When the tension is constant, the heavier the bobbin is, the tighter the tension is. Therefore, it can be understood that the large yarn is wound more tightly than the small yarn.
Solution: The graded tension can be opened, which can tighten the tension when the yarn is small and loosen the tension when the yarn is large, so as to keep the tension of the bobbin yarn as consistent as possible, thus improving the problem of adhesion and breakage.
Another cause of adhesion is the high feather. As we all know, the hairiness of the tube yarn will increase a lot after the winding process, so the growth rate of hairiness in the winding process should be reduced as much as possible. In terms of reducing hairiness, reducing the winding speed is the simplest, convenient and effective method, but it affects the output. The second is to ensure smooth passage and reduce friction points. The pre-clearing device can be removed, the air ring rupturer can be set to an open state, and each porcelain nozzle on the friction point can be checked for damage. In addition, in terms of technology, hairiness can be reduced by adopting a small tension process design. Of course, the root cause of high hairiness still needs to be solved by the previous process, such as unreasonable process and raw material problems.
2. unring and head broken
A broken end is a broken end caused by multiple yarns or strands being brought out by a high-speed unwinding yarn. The reason is that the tension of the bobbin yarn is small and the bobbin winding is too loose. Contrary to the cause of adhesion breakage, reference can be made to the tension control method at the time of adhesion breakage.
3. disordered layers or broken ends
The phenomenon of disorderly layer is that the yarn is not wound onto the bobbin according to the groove rule of the groove drum; while the phenomenon of yarn return is that the yarn is attached during the yarn winding process. Generally, normal winding will not produce these two phenomena. After long-term observation, the causes are related to the repeated yarn suction of the large suction nozzle and the negative pressure of the main air suction motor, followed by the disorderly layer caused by the bobbin yarn when the large suction nozzle sucks the yarn.
Solution:
Adjust the distance between the large suction nozzle and the bobbin one by one, and keep the gap of 3mm-5mm;
Check whether there are repeated joints caused by unqualified splicing of single spindle or fault of yarn detection sensor;
Check whether there is a phenomenon that the car blocker directly presses the single spindle start button without handling the bobbin yarn, and strengthen the training of the car blocker;
Whether the yarn cleaning process setting is too strict, resulting in frequent joints;
The number of times of yarn finding in the "cycle" menu can be adjusted from 3 times to 2 times or even 1 time to reduce the number of repeated yarn suction;
Reduce the rotation speed of the suction motor at the front of the car to reduce the negative pressure of the suction yarn of the large suction nozzle;
Strengthen equipment management, personnel training and site management.
4. irregular decapitated head
1, the splicing strength is low, to check whether the splicing configuration is reasonable, whether the splicing process to achieve the best results.
2. Broken ends caused by weak twist yarn are more common in coarse varieties, that is, no twist is added in the twisting process of spun yarn, and the strength is also very low, so it is necessary to optimize the yarn cleaning process.
3. Details are broken. If the yarn cleaner does not cut off small defective yarns, spun yarns and yarns with poor strip dryness, the strength is low, which will cause the whole warp to be broken. It is also necessary to optimize the yarn cleaning process.
With the popularization of automatic winding machine, the output proportion of automatic winding bobbin yarn will be larger and larger. How to reduce the broken end of the whole warp caused by the bad of automatic winding bobbin yarn is particularly important. Go deep into the site, find and solve problems, operate, clean and repair in strict accordance with the operation method, and ensure that the equipment is in the best working condition. Only in this way can we use the advantages of the automatic winder to spin good products.
