6. Manually lifting the sliver roller; 2. The Draw Texturing Yarns Manufacturers reasons for the generation of long details can be referred to as follows: 1. After the wrapping roller is rolled, the defective sliver cannot be found. Spun yarn: 1. Spinning yarn: 1. The joint is unqualified and too thin; 5. For the thin strips caused by the previous process, the lack of stock feeding, etc. 4. During the unwinding process of the roving, the cradle axis, the yarn guide rod, the skin roller, etc. Inflexible rotation of the hanging spindle; 4. In actual production, many factors can cause different types of long details. 2.
The sliver is operated during transportation and handling Improper damage to the sliver; 4. In view of various factors that are prone to produce long details, a comprehensive inspection and assessment system is formulated. Active process trial spinning, choose the best tension configuration. Gears should be well meshed and aging gears should be eliminated. burrs and sticky cotton wax caused by yarn channels such as spindle caps, hollow arms, rear bell mouths, etc . Strengthen equipment maintenance, smooth spinning channel, no cotton wax, stickiness, burr, and other key parts such as upper pin and palm press should be periodically adjusted. appear around the normal passage without passing through the normal channel, which is likely to cause accidental drafting. Second, long details of preventive measures: 1.
The responsibility lies with the people and the offenders must be investigated. The drafting area is poorly cleaned, the aprons are pinched, the upper pin is lifted, and the draft is accidental; 3. In short, excessive tension in each process will provide more opportunities for accidental drafting. Final draw: 1.
Hanging burr hanging flower; 3. Hanging rusty burr hanging flower; 2.; unexpected tension increase; 3, upper pin skewed, palm deformation Wait until the sliver is accidentally drafted; 4. Excessive tension on the guide bar of the roving frame; 2. Improve the level of operation and management so that new employees can understand the basic quality requirements of yarn with quality awareness. The coil tension is too high., we must have a sense of catching flaws.
