To get a deeper understanding of PP staple fiber, you must first understand how air spinning is going.

Air spinning is a new spinning technology that uses airflow to condense and output the fibers into a spinning cup at high speed. He does not need a spindle, but mainly relies on multiple components such as a carding roller, a spinning cup, and a false twist device. The opening roller is used to grab and comb the fed sliver fiber, and the grabbing fiber can be pulled out by the centrifugal force generated by his high-speed rotation.

Is PP staple fiber used for air spinning or ring spinning?

Air spinning and ring spinning are new textile technologies, one is old-fashioned spinning technology. Air spinning is air spinning, while ring spinning is mechanical spinning, which is twisted by spindles and steel bells and wire loops, and drafted by rollers. In the case of air spinning, the fibers are transported by airflow and held at one end by twisting. Generally speaking, the hairiness of the ring yarn is more than that of the airflow, the strength is higher, and the quality is better. The air spinning process is short, and the protruding hairiness is less, especially the viscose fiber is more obvious, the fiber on the yarn does not break, but many hairiness is wrapped around the yarn body, so the rotor yarn has less hairiness. The number and intensity are not high and the price is low.

From the perspective of the yarn body structure, the ring spinning is relatively tight, and the air spinning is relatively fluffy, the style is rough, suitable for denim fabric, and the air-jet spinning yarn is generally thick. Therefore, PP staple fiber is suitable for air spinning, and the fabric is more fluffy.
