●1. Ring spun yarn refers to the yarn twisted by traditional spinning method on the ring spinning frame. The inner and outer fibers in the yarn are intertwined and connected, so the yarn structure is tight and the strength is high.
●2. Open end yarn refers to the yarn formed by coagulation and twisting of fibers in the high-speed rotating rotor flow field or in the electrostatic field. The twisting and winding of the yarn are completed by different components, so the efficiency is high and the cost is low.
●The representative of free end spinning - rotor spun yarn: (OPEN END) is also called rotor spinning, which uses the air flow to condense and twist the fibers in the spinning cup at high speed and output them into yarn. Airflow yarn features: the yarn structure is looser than ring spinning yarn, wear-resistant, evenness, bright dyeing, but lower strength. It is mainly used for bulky plain cloth and fine felt flannelette in woven fabrics.
