Using a core-spun yarn is a great way to make beautiful designs in different fabric types- Suzhou RHZ Textile Technology Co., Ltd.

The core-spun yarn can be knitted with other yarns for different purposes.The process of producing core-spun yarn can be done by several spinning systems. Among them, conventional ring spinning is the most popular and inexpensive. This system requires a core to be placed in the center of the spinning wheel. It is a simple process, but may cause the core filaments to get twisted. However, this process produces high-performance yarns.

Another spinning system is rotor spinning. This system is cheaper and is more efficient than traditional ring spinning. In rotor spinning, a core is not twisted during the process. It is spun with one or more endless filaments. In this process, a rotor is used to rotate the core. It is then wrapped with staple fibers. Depending on the quality of the filaments, the input tension varies. It should be a minimum pretension to prevent the filament from being flung out into the collecting surface of the rotor.

Another technique, used to produce core-spun yarn is two-rove feeding. In this system, a colored filament is fed over a tension device before the nip of the front roller of the ring frame. This increases the overall strength of the core yarn because of improved fiber alignment. Moreover, two-rove feeding improves core control.

Besides the benefits of core-spun yarn, it is also an excellent choice for those who want to produce durable and wearable textiles. Core-spun yarns can reduce wear and tear by 40% to 50% compared to regular spun yarns. It can also help to prevent break stitches in denim stitching, especially in the hem.

Core-spun yarn is also a great choice for sewing threads. It can be spun with metal needles and can be knit with several different types of threads. It has good durability and can be re-dyed without losing its original color.
