In addition to its special structure, core-spun yarn has many advantages. It can make use of the excellent physical properties of the core yarn chemical fiber filament and the performance and surface characteristics of the outer short fiber to give full play to the advantages 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 filament, anti-folding wrinkle, easy to wash and quick-drying, while giving full play to the advantages of the outer cotton fiber, which has good moisture absorption, less static electricity, and is not easy to pilling. The woven fabric is easy to dye and finish, comfortable to wear, easy to wash, and bright in color, beautiful and generous. Core-spun yarn can also reduce the weight of the fabric while maintaining and improving the performance of the fabric, and use the different chemical properties of chemical fiber filament and outer fiber. During the dyeing and finishing of the fabric, chemicals are used to rot a part of the outer fiber to make a rotten fabric with a three-dimensional pattern effect. The use of core-spun yarn, currently with cotton as the skin and polyester as the core, is the most widely used, and can be used to produce student uniforms, work clothes, shirts, bathrobe fabrics, skirt fabrics, sheets and decorative fabrics. An important development of core-spun yarn in recent years is the use of core-spun yarn with a polyester core covered with viscose, viscose and linen or cotton and viscose blends, as well as core-spun yarn covered with cotton and silk or cotton and wool blends in women's clothing fabrics. These products are very popular.
