The spindle is short of oil, the traveler is too light

In order to improve wholesale DTY yarns quality, reduce end breaks and reduce yarn defects, spinners must not only be proficient in operating techniques, but also be familiar with mechanical properties and be the master of the machine. In the actual production process, spinners want to combine basic operations to prevent mechanical defects, mainly from the following aspects. When pulling and pulling yarn, the feel of the tube is thick and hard, after checking, the rubber roller is not in place, the pressure fails, the rubber roller is short of oil, the roving is wound after the roller, the roving does not pass through the bell mouth, the roving is fed with two roots, the traveler is too heavy, and the spindle Belt slide on the ingot tower and so on.

The feel of the tube is loose, the spindle is short of oil, the traveler is too light, the roving is not good, the spindle belt is loose or slipping out of the spindle, and there is more silk on the spindle or in the bobbin. When looking for something, see if there is a feather problem on the bevel of the tube yarn, check the collar is rough and floating, the traveller is wrong or worn, the spindle is twisted, the steel plate is suspended, the sliver jumps out of the collector, the cleaner fails, and the partition plate is rough, etc. . When drawing the yarn, see that the drawn yarn is uneven and sticky.

Check the bell mouth of the drafting component, block it, skew it, the yarn touches the rubber ring frame, the collector is damaged, the flower is accumulated, the internal inclusions are flying, and the yarn is sliver. Jump out of the collector, accumulate flowers under the aprons, crack the aprons, deformation, trapped impurities in the fly, deformation of the aprons, jitter, no aprons, roller jitter, and bad roving. Lower rubber ring deflection, lack, damage, deformation, nylon plug block reverse installation, lack, misuse, deformation of tension disk, blockage, not falling groove, rubber shell peeling, etc.

However, too small carding interval can easily cause fiber damage and cylinder damage. Therefore, the determination of the combing distance of the cylinder should be optimized according to the density configuration of the cylinder rack, the volume of small coils, and the customer's quality requirements. 4.
