Comparison and difference between core yarn and other yarn materials

Core yarn is a special kind of yarn material, which has some differences with other yarn materials in terms of use and performance. In this paper, we will compare and differentiate core yarn with other yarn materials in terms of fiber material, spinning process and application scope.

First of all, for the fiber material point of view, core yarn is usually made by combining two or more fibers. The fibers wrapped around the outside are called core fibers, which can be a variety of materials, such as cotton, polyester, nylon and so on. The inner fibers are fibers with strength and elasticity, such as polyester fibers, nylon fibers and so on. While other yarn materials are usually composed of a single type of fiber, such as cotton yarn, polyester yarn, and so on. Therefore, core yarn in the fiber material and other yarn materials there are obvious differences.

Secondly, for the spinning process, the spinning process of core yarn is relatively complex. In general, core yarn needs to go through the process of spinning and then twisting. In the production process of core yarn, the internal strong fiber is first spun into a yarn, and then the outer core fiber is wound around the internal strong fiber. This process gives the core yarn better strength and tensile properties, compared to other yarn materials that use a simpler spinning process. This difference also demonstrates the advantages of corespun yarns in terms of tensile uniformity and strength.

In addition, in terms of performance, core yarn has better toughness and abrasion resistance than other yarn materials. Because the core fiber outside the core yarn has better abrasion resistance, the internal strong fiber has better toughness, so the core yarn is not easy to break in the process of use. While other yarn materials may have the problem of easy to break and easy to wear in the process of use. In addition, the core yarn has better elasticity and can better maintain the appearance and shape of the textile, while other yarn materials may have larger deformation problems.

In terms of scope of application, core yarns are widely used in knitting, weaving and sewing. Due to its good tensile uniformity and strength, core yarn is suitable for making knitwear and fabrics with high requirements. While other yarn materials have different scope of application according to different fiber materials, such as cotton yarn is suitable for making summer garments, polyester yarn is suitable for making sportswear and so on.

To sum up, there are obvious differences between core yarn and other yarn materials in terms of fiber material, spinning process, performance and scope of application. Therefore, in the process of material selection and use, it is necessary to choose the appropriate yarn material according to the specific needs.
