The traveler is responsible for the important tasks of twisting and winding of the spinning frame. If used improperly, it will affect the quality of the spinning yarn. Based on practical experience, the experience of using wire rings is summarized as follows.
The condition of the steel ring has a greater impact on the use of the traveler
Accurately grasp the condition of the steel ring The replacement cycle or regrinding time is the basis and key to better play the role of the traveler. The deterioration and aging of the steel ring will shorten the service life of the traveler, easily causing more flying rings, difficulty in production, and an increase in neps, hairiness and yarn defects. After the steel ring has been used for a period of time, if it is found that the shape of the balloon becomes smaller, it is easy to shake, there are many flying circles, and the yarn hairiness index increases, it indicates that the steel ring has entered a period of decline; especially bearing steel or alloy steel rings are declining to Serious quality problems may also occur during the grinding and replacement period. For example, when spinning pure cotton combed yarn, belt-like long hairiness will easily occur in the middle of the spun yarn bobbin (severe black hairiness may appear). The upper part of the yarn produces dense rice-like yarn defects. According to practice, the grinding cycle for ordinary steel rings is generally controlled at 9 months, and for bearing steel and alloy steel rings at about 24 months. It should be noted that the traveler must be replaced before the ring decline approaches the grinding period. The cycle should be shortened appropriately to ensure normal workshop production and avoid related quality problems or accidents.
The principle of controlling the weight of the traveler
Do not increase the number of wire rings after breakage Under the premise of choosing a heavy wire ring, it can effectively reduce the phenomenon of burnt and flying rings of the wire ring. When the traveler is controlled lightly, it is best to observe that the balloon does not hit the yarn separation plate, which not only ensures that the yarn is not hit, but also allows normal production; when the traveler is controlled heavier, it is best to observe that the balloon does not touch the end of the spun yarn tube and has fewer breakages. As appropriate.
Effective use of traveler cleaners
There are fewer cleaners The traveler has the function of hanging flowers and keeping the yarn passage smooth. The spacing of the cleaner is generally 1.8 mm to 2 mm. If the spacing is too large, it will not have a cleaning effect. If the spacing is too small, it will easily collide with the wire ring and cause the wire to break.
The service life of the traveler
The reasonable service life of the traveler It is determined after repeated tests and comprehensive changes in yarn quality indicators and spun yarn production conditions. The hairiness and neps of the yarn spun by machines beyond the replacement cycle will increase. Because different types of wire rings use different models and cycles, they must be distinguished by category. For example, a certain type of wire ring has a service life of 7 days. If it is not replaced after the 8th day of use or a 5-day wire ring is misused on this type of wire, it will inevitably cause more broken ends and increased hairiness.
Precautions when changing varieties
The spinning frame changes from a coarser yarn to a finer one Number yarn varieties often have a maturation period. For example: if the original spinning 18.5 tex machine is converted to spin 14.5 tex or finer yarn, there will be many ends broken during the initial modification, making production difficult. This is because new types of wire rings need to be ground on the steel ring in the early stages of machine installation. This can generally be solved by replacing the wire rings within 24 hours of production of the new type. When changing types, it is necessary to promptly replace the wire rings in the spare wire ring container at the front or rear of the car to prevent the turner from using the wrong one when replacing the flying ring.
Doing the above points carefully will help make good use of the traveler, which will help reduce end breakage, reduce hairiness, and improve yarn quality. </p
