1. It can meet the requirements of high-speed economic development and high-yield. The sawtooth of metal card clothing is shorter or shorter, and the gap is large at the top and small at the bottom, and there are not easy to fill fibers between the teeth; Keep a tight gap. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery.
According to the spinning process, carding is an important process. The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit.
It is beneficial for enterprises to strengthen the important role of students' combing; at the same time, the metal card clothing is firmly wrapped, unlike other elastic card clothing companies, after running for a long time, the base cloth is prone to slack or the card clothing floats due to low-speed operation. . Therefore, metal card clothing can better meet the process design requirements of high speed, heavy load and strong carding in China. 2. The tooth shape specification of the metal clothing with strong spinnability can be processed according to different types of fibers, and different process requirements are adopted. The appropriate specification parameters and special window design are selected to make it suitable for brocade and various chemical fibers. Good spinning properties.
3. Long cycle of needle copying Because the teeth of Chinese metal clothing are short and the amount of residual fibers between teeth is small, we can do not copy needles for a long period of time, but only regularly remove broken seeds or dead silk blocks, and the needle-copying cycle It can be extended, which can improve the utilization rate of teaching equipment resources, reduce the intensity of labor relations in the enterprise, and have a beneficial effect on the uniformity of output products. There are also some problems with card clothing. If the wear resistance of the needle tip is poor, the sharpening times are more, the needle tip becomes smaller, the plane increases, and the sharpness becomes ashamed; in actual production, it is often crushed by hard chips or small masses; A lot of fly dust mold.
These issues need to be further addressed in the future.
