What is core yarn？

Core-spun yarns are generally made of synthetic filaments with good strength and elasticity as the core filaments, wrapped with short fibers such as cotton, wool, and viscose fibers by twisting together. The core-spun yarn has the excellent performance of filament core yarn and short-wrapped fiber. The more common core-spun yarn is polyester-cotton core-spun yarn, which uses polyester filament as the core yarn and wraps cotton fibers. There is also spandex core-spun yarn, which is a yarn made from spandex filaments as the core yarn and outsourcing other fibers. The knitted fabric or jeans material made of this core-spun yarn can stretch freely and fit comfortably when wearing.

Its main purpose is to strengthen the cotton canvas and maintain the water repellency of cotton fiber swelling when exposed to water. The polyester fiber has stretch resistance, tear resistance and shrinkage resistance when it is damp in the rain. At this stage, the core-spun yarn has developed into many types, which can be summarized as: short fiber and short fiber core-spun yarn, chemical fiber filament and short fiber core-spun yarn, chemical fiber filament and chemical fiber filament core-spun yarn. At present, many core-spun yarns are generally composed of chemical fiber filaments as the core yarn and covered with various short fibers to form a unique structure of the core-spun yarn. The commonly used chemical fiber filaments for its core yarns include polyester filaments, nylon filaments, and spandex filaments. Outsourcing short fibers include cotton, polyester cotton, polyester, nylon, acrylic and wool fibers.

In addition to its special structure, core-spun yarn has many advantages. It can take advantage of the excellent physical properties of core yarn chemical fiber filaments and the performance and surface characteristics of short-coated short fibers to give full play to the characteristics of the two fibers and make up for their shortcomings. For example, polyester-cotton core-spun yarn can give full play to the advantages of polyester filaments that are crisp, crepe-resistant, easy to wash and dry, and at the same time can take advantage of the characteristics of the outer cotton fiber that it has good moisture absorption, low static electricity, and is not easy to fluff and pilling. The woven fabric is easy to dye and finish, comfortable to wear, easy to wash, bright in color, and beautiful in appearance. The core-spun yarn can also reduce the weight of the fabric while maintaining and improving the properties of the fabric. It also uses the different chemical properties of the chemical filament and the outer fiber. During the dyeing and finishing of the fabric, a part of the outer fiber is rotten by chemicals to make it. Burnt-out fabric with three-dimensional pattern effect, etc. The use of core-spun yarn is currently the most widely used core-spun yarn with cotton as the skin and polyester as the core. It can be used to produce school uniforms, work clothes, shirts, bathrobe fabrics, skirt fabrics, sheets and decorative fabrics. An important development of core-spun yarns in recent years is the use of polyester core yarns covered with viscose, viscose and linen or cotton and viscose blends, as well as cotton and silk or cotton and wool. Blended covered core-spun yarn, these products are very popular.
