Light and heavy, High Intermingled Yarns Suppliers not close the cotton table; rollers, rubber rollers, slivers are uneven, light and heavy, do not remove the combed cotton net Holes or overlapping sticky rolls; and, after thick drafting, long thick sections and long details are formed. Only from subtle points and continuous improvement can we reduce the occurrence of yarn defects. The focus is on equipment and operating reasons. The losses are large, and sometimes they bring customers' economic claims. If the gripping force is greater than the drafting force, details will be formed; on the contrary, if the gripping force is less than the drafting force, a thick section will be formed. In the spinning process from clearing to carding, combing, combing, and thickening to spun yarns, there are excellent semi-finished products that are the basis of good yarns,
so to find out the reason, pay attention to the problems that may arise at the source. ► The roving winding formation is faulty. During the running of the tendon, the upper and lower apron are intermittently rotated, which will also produce coarse details. In view of the above-mentioned operational factors,
it is necessary to improve the quality awareness of the stopper, hold more quality analysis meetings, and carry out more activities to catch and prevent defects. ► When the car is turned on and off at the last time, all the bad slivers are not removed; the sliver is split or stacked after the roving machine, and the sliver floats into the adjacent yarn after the end of the roving machine is not removed in time; Thick and thin yarn defects may also occur if the yarn is not removed.14 x d (roller diameter) x E (drawing multiple of the problem part to the front roller).
Based on the roller level, the pressure of the rubber roller is not on the same level, so that the sliver is stressed differently when it passes through the pressure jaw. Under the condition of sufficient turnover, this can effectively reduce the coarse and fine yarn defects caused by the poor toe cap during yarn changing and changing.. According to the length of the mechanical wave, the problem can be found out by using the formula L (wavelength) = 3. Poor pressure is also manifested in the position of the rubber roller. Therefore, in the process of changing the yarn number, especially when changing the variety, we must observe the sliver arrangement. .
