Introduction to air-jet spinning and air-jet spinning machines 2019/12/28

Air-jet spinning is a new technology in the spinning field. With its high yarn quality, short process, high output, wide range of suitable spinning, low labor, and high degree of automation, the comprehensive technical level and economic advantages have become the focus of the textile industry. technology. The air-jet spinning machine is most suitable for the production of chemical fiber yarns of the same long fiber and the blended yarns of chemical fibers and natural fibers, especially for the production of differentiated fiber yarns, such as the production of fine denier fiber yarns. Natural fiber with poor uniformity. The process of air-jet spinning is simple. After the four-roller double-aperture high-draft, the discharged sliver directly enters the nozzle. The nozzle twists the sliver with compressed air to form a yarn, which is then drawn out by the yarn introduction roller and cleared. The bobbin yarn is wound on the bobbin, and the roving process can be omitted in the front spinning, and the winding process can be omitted in the post spinning. Air-jet spinning is characterized by the production of fine special yarns (high count yarns), which can adapt to pure and blended spinning of natural fibers, synthetic fibers, and cotton-type fibers, but it is difficult to spin pure cotton.The main principle of air-jet spinning is that after the draft is falsely twisted by the jet airflow, some of the free fibers on the end of the fiber are wrapped around the fiber to spin. There are two types of single-nozzle and double-nozzle, the latter spinning quality is good and stable. The fiber strip is thinned by the drafting device, and is output from the front roller, and is wound into a bobbin by a groove tube through a first nozzle, a second nozzle, a yarn guide hook, and a yarn introduction roller. The vortex rotation direction of the two nozzles is opposite, and the vortex strength of the second nozzle is greater than that of the first nozzle, so that the twist on the sliver between the two nozzles can overcome the torque and resistance added by the first nozzle to the sliver, and it is transmitted to the front roller. At the jaws. The free end of the twisted fiber at the periphery of the fiber strip is affected by the first nozzle, and is wrapped around the fiber strip in the opposite direction. The twisted core core fiber is retracted through the nozzle, and the wrapped fiber is In the reverse withdrawal process, the package becomes tighter and tighter. It provides yarn strength and cohesion. Compared with ring spinning, air-jet spinning has the advantages of high output, large package and short process. Air-jet spinning speed ranges from 100-200 m / min, and the suitable spinning count range is 5.5-3.0 tes. The output is 10 times of ring spinning and 2 times of air spinning. It is suitable for spinning all kinds of staple fiber and filament core-spun yarns, and processing pleated medium-long chemical fiber yarns. Air-jet spinning looks like air-jet spinning, with a hard hand and good hairiness.Changzhou Fubang Chemical Fiber Machinery Factory mainly produces: polypropylene spinning machine, polyester industrial silk spinning combined machine, polyester POY spinning machine, polypropylene FDY spinning machine, polypropylene FDY production line, polypropylene FDY equipment, polypropylene FDY machinery, polypropylene spinning Machine, polyester FDY spinning machine, polypropylene spinning machine, polyester FDY production line, polyester FDY machinery, nylon FDY spinning machine, polypropylene spinning machine.......
