What are the common reasons for yarn breakage during yarn doubling machine operation

In the yarn production process, the quality of the yarn is the key factor affecting its breakage rate. The strength, uniformity and fiber integrity of the yarn directly determine its performance in the two-for-one twisting process. If the yarn strength is insufficient, or there are problems such as fiber breakage and uneven yarn thickness during production, the yarn will break during the two-for-one twisting process. In addition, the humidity and storage conditions of the yarn also have a significant impact on its quality. If the yarn is damp during storage, it may cause fiber adhesion, thereby affecting its performance in the two-for-one twisting process. Therefore, ensuring the use of high-quality yarn and storing it under suitable environmental conditions is the basis for preventing yarn breakage.

The rationality of the tension setting is also an important factor affecting yarn breakage. During the operation of the yarn doubling machine, the role of the tension control system is crucial. If the tension is set too high, the yarn will be subjected to excessive tension during processing, which is very likely to cause breakage; conversely, if the tension is set too low, it may cause the yarn to relax, thereby affecting the two-for-one twisting effect. Therefore, the operator should scientifically adjust the tension setting of the yarn doubling machine according to the characteristics of the yarn and production requirements to ensure that the appropriate tension is maintained during processing, thereby effectively reducing the occurrence of breakage.

In addition, the running speed of the yarn doubling machine is also an important factor leading to yarn breakage. The running speed of the yarn twister directly affects the processing effect of the yarn. If the yarn doubling machine runs too fast, the tension on the yarn during the twisting process increases, increasing the risk of breakage. At the same time, too fast running speed may cause uneven yarn winding, further affecting the quality of the final product. Therefore, when setting the running speed of the yarn doubling machine, the operator should combine the characteristics of the yarn and production requirements to select the appropriate speed to ensure the safety and stability of the yarn during processing.

The wear and maintenance of the equipment are also potential causes of yarn breakage. With the increase of use time, some parts of the yarn twister, such as the yarn guide wheel, tension device and twisting device, may wear out. These worn parts may cause uneven friction when the yarn passes through, thereby increasing the risk of breakage. Therefore, enterprises should establish a regular maintenance system, regularly check and replace worn parts to ensure the normal operation of the equipment. At the same time, operators should clean the equipment regularly to avoid the accumulation of dust and debris that affect the performance of the equipment.

The skills and experience of the operator also greatly affect the breakage of the yarn. If the operator is not proficient in the operation of the equipment, it may cause incorrect operation, such as improper tension adjustment or speed setting, which will increase the risk of yarn breakage. Therefore, strengthening the training of operators and improving their understanding and operation ability of the equipment is an important measure to reduce yarn breakage. Enterprises should organize training regularly to ensure that each operator can master the correct operating procedures and precautions, so as to improve the operating efficiency of the equipment and product quality.
