西昌Core yarn

Core-Spun Yarn is a yarn consisting of one or more continuous fibers. In Core-Spun Yarn, the main fiber strand is wrapped around another fiber, forming a structure that wraps around the main strand. The fiber that wraps the main thread is called Core-Spun Fiber, and the main thread it wraps is called Main Fiber.

Core yarns are typically made in a two-step process: First, the core fiber is wrapped around the main thread by feeding the main fiber into a spinning machine loaded with the core fiber. Then, by stretching and twisting, the core fibers are tightly bonded to the main fibers to form the final core yarn.

Core yarns offer a number of advantages. First, because the main fibers in a core yarn are encased in the core fibers, it has better strength and abrasion resistance. This makes corespun yarns very useful in making rugged textiles such as ropes, netting and sports equipment. Secondly, the appearance and texture of the core yarn is controllable. By choosing core fibers from different materials, the look, feel and function of the yarn can be altered to meet different textile needs. For example, the use of core fibers with moisture absorption can produce sportswear with moisture wicking function, and the use of core fibers with waterproof function can produce waterproof clothing and waterproof appliances.

Secondly, the coloring performance of core yarn is superior. Because the main fiber is wrapped, the surface area of core yarn is less than that of ordinary yarn. This means that core yarn has less surface area to absorb dye during the dyeing process, requiring less dye and better dyeing uniformity.

In addition, because core yarn has a lower dye absorption capacity during the dyeing process, it can better control the diffusion and migration of dyes, which reduces the problems of color contamination and uneven dyeing that exist in textiles during the dyeing process.

The most common application area for core yarn is the textile industry. It is widely used to make various types of textiles such as garments, home furnishings, and industrial goods. Especially in the field of sports equipment manufacturing, the advantages of core yarn are fully utilized. Sports equipment needs to be characterized by abrasion resistance, moisture wicking and comfort, and core yarn possesses exactly these characteristics. Therefore, it is widely used in making sportswear, sports socks, sports shoes and so on.

In short, core yarn is a type of yarn formed by wrapping the main fiber in a core fiber. It has better strength, abrasion resistance and dyeing properties, and is suitable for the production of various textiles. Especially in the field of sports equipment manufacturing, core yarn is playing an important role. With the continuous progress and innovation of technology, the application range of core yarn will continue to expand.
