The working principle of an airspinning machine is based on the stretching and twisting of yarns by high-pressure jet airflow. The mature strips are directly fed into the spinning cup of the airspinning machine, and with the help of high-speed airflow, the fibers form a conical spiral that transfers inside and outside. The negative pressure during this process creates a certain frictional force between the fibers and the airflow, causing the fibers to move along the spiral and entangle with each other. At the same time, the airflow inside the spinning cup is very fast, causing the fibers to form a strong rotating airflow in the spinning cup, which in turn produces a stretching and twisting effect.
During the spinning process, the rotor speed of the rotor spinning machine is very high, reaching up to 600000 revolutions per minute, greatly improving the production speed. The yarn continuously rotates inside the spinning cup, forming a relatively coarse yarn, usually less than 30 count. Due to the high speed and large yarn volume during the spinning process, the airflow spinning machine has the characteristics of high production efficiency, dry yarn, and good hairiness.
Although air flow spinning machines have advantages such as high speed, large yarn rolls, wide adaptability, and simple structure, they cannot completely untwist the entire yarn like ring spinning, which is also a disadvantage of air flow spinning machines. Due to the process characteristics of air flow spinning, the air flow spinning machine is also prone to breakage during the spinning process, which may affect yield, quality, and yield.
Airflow spinning machines are suitable for producing products with tight fiber structures such as denim fabrics, and their market share is gradually increasing, entering the third generation.
