The number of broken ends in the thousands of spindles is a comprehensive indicator reflecting the production management of the textile mill, and it is also a comprehensive performance of high yield, high quality and low consumption. There are many broken ends of the yarn, which not only can not stabilize the normal production, but also affect the quality of the yarn and the fabric, which is not conducive to energy saving and consumption reduction. Therefore, reducing the yarn breakage is a work that must be paid attention to during the spinning process. The following is a brief description of the causes and solutions for the breakage of the yarn at different stages.
1, small yarn breaks
Reduce the breakage of the small yarn from the control of the good air ring, such as the production of the machine table when the formation of the bottom of the tube is broken, the broken head is more concentrated, and when the big yarn is not broken, the steamed bread is lighter, this situation belongs to the wire ring matching Improper (too light) or steel collar decline, the time of use of the car to the cycle and other reasons.
Solution:
(1) Combine the actual weight-regulating wire ring;
(2) Exchange the steel collar;
(3) Appropriately lower the foliar triangle to reduce the balloon expansion problem;
(4) The maintenance worker shall timely process the boring spindle and the crepe board.
2, medium and large yarn breaks
If the yarn breakage of the production machine is normal, and the break of the large yarn is higher, the air ring is relatively flat, the elasticity is small, and the head is heavy. This phenomenon is caused by the large friction between the wire ring and the steel ring. The coiled parts are not working properly or the sliver channels are not grooved or dirty.
Solution:
(1) Adjusting the number of light wire rings;
(2) Change the size of the wire ring to reduce the friction of the spinning;
(3) Appropriately raise the fender triangle iron, adjust the height of the balloon at the time of the large yarn, and reduce the breakage;
(4) Exchange the grooved winding parts, such as guide hooks.
In short, the yarn breakage is related to the cotton, semi-product quality, spinning equipment, process, equipment, operation and temperature and humidity. The main direction of reducing the break of the yarn is to control the balloon, stabilize the tension, improve the uniformity of the yarn, improve the strength of the single yarn, reduce the unevenness of the strength, especially reduce the sudden change of tension and strong weak links, in order to reduce the breakage and improve the yarn. , the quality of the cloth surface and the expected effect of energy saving.
