2. Mechanical yarn cleaning devices mainly include: yarn cleaning plate type, comb tooth type, waist drum type and so on. , available for different yarn varieties to choose from.
Use. Mechanical yarn cleaner is widely used because of its simple structure, convenient maintenance and being unaffected by temperature and humidity. However, due to its defects such as easy to scratch the yarn, damage the fiber, unsuitable for high-speed winding, flat yarn, easy to leak details and so on, the yarn cleaning efficiency is low, generally only about 30%, so it has been gradually eliminated, or only used as pre-cleaning for self-winding machines.
3. Electronic yarn clearer: Due to the above defects of mechanical yarn clearer, several generations of electronic yarn clearer have been successfully developed in order to remove harmful yarn cover to the maximum extent and further improve yarn quality. The electronic yarn cleaner has the advantages of not scratching the yarn, not damaging the fiber and adapting to high-speed winding. At the same time, different yarn cleaning curves can be set according to the thickness and length of yarn defects, and the general winding efficiency can reach above 80%. With the continuous development of modern electronic technology and computer technology, the performance of yarn clearer is further improved and perfected, and its function is more powerful. When the winding speed is 1500m/min, the accuracy of cutting defects by advanced electronic yarn clearer can still reach over 90%.
