Fluoride bead is coated to improve yarn quality - PEM Fastener - China Machined Parts

As we all know, spinning and wire loop type of steel to make the configuration; steel orders, the quality of the stability of the wire loop; steel orders, traveler's reasonable replacement cycle configuration will directly affect the intrinsic quality of the yarn and look. Currently, bead manufacturers in more domestic production, product quality is also uneven bead using a short cycle, plate off the white more frequent replacement, large amount, and the quality of batches of the traveler and the individual difference directly affected the quality of the yarn, so that breakage increases, resulting in production of very unstable. To this end, the surface coating on the steel ring fluoride treatment, will greatly improve the resolution of these problems.
In the high-speed operation, the yarn due to be made of steel wire ring friction and easy shaving, scratching and Guaduan. Steel wire ring so that the friction and heat generated by it to the interior angle bead, fever, or even damage, ignition, ring hardness decreased, increased production of cotton yarn hairiness, and so that the yarn surface fibers in a semi-molten state , produce large amounts of powder down in the steel, which is usually referred to off white. Meanwhile, the wire ring on the clip with ribbon gauze of the powder plot twist into the yarn attached to form neps, affect quality of yarn. The fluorine-plated wire ring is plated bead surface after fluoride treatment, so wear good, self-lubricating high performance, its maturity is short, use the cycle is long, yarn quality and stability.
By C14.5tex bead on the bus test, an ordinary steel to make bead production cycle to 14 days, while the fluorine-plated steel ring production up to 28 days. From the test data shows that little change hairiness, hairiness on the train number on day 1 289.98 / 10 m, on the bus number 9 days hairiness 267.54 / 10 m, on the bus number 14 days hairiness 282.37 / 10 meters, on the train the first 21 days hairiness number of 275.76 / 10 m, on the train the first 28 days hairiness number of 286.28 / 10 m, can be seen that fluorine-plated steel wire loop to extend the life cycle have a significant effect.
From the production of pure polyester varieties, due to large pure polyester fiber strength, toughness, easy to wear steel ring, ring temperature is higher, in order to yarn quality, can be pure polyester varieties of bead cycle control in 5 to 7 days but mature long, just on the car, wear, ignition, gap phenomenon is particularly serious, mature long, each bead must be changed to play a slow, broken ends more winding roller is serious, not only caused the back flower back to wire the amount of increase and Tender workload increased, did not say run tour, so clean, even the broken ends are never-ending, while the use of fluoride-plated steel wire ring, the machine life is relatively stable, short maturity, decapitation little, and as long as the progress made by clean, fly into a group, actively took longer exists.
Cloth surface of the stars is mainly caused by wire loop yarn faults, which have seriously affected the control of plant indicators of yarn faults. Therefore, effective control of the stars has become the focus we have chosen the traveler, especially in the weft species directly, the wire ring on the bus cycle must be 14 days (one arrangements of train), and general bead simply can not meet his request, on the train about 7 days the stars began to appear. Therefore, all direct weft fluorine coating on the wire loop are used, and can basically meet the production requirements.
