There is also spandex core-spun yarn, which is made of spandex filament as the core yarn and outsourced from other fibers. The knitted or jeans material made of this core spun yarn stretches and fits comfortably when worn. Its main purpose is to strengthen the cotton canvas and maintain the water repellency of the cotton fiber when it is swelled by water. Polyester is used to resist stretching, tearing and shrinkage when it is wet in the rain.
At this stage, the core-spun yarn has developed into many types, which can be summarized into three categories: staple fiber and staple fiber core-spun yarn, chemical fiber filament and staple fiber core-spun yarn, chemical fiber filament and chemical fiber filament core-spun yarn. At present, most core-spun yarns generally use chemical fiber filaments as the core yarns and wrap various short fibers to form core-spun yarns with a unique structure. The commonly used chemical fiber filaments for its core yarns include polyester filaments, nylon filaments, spandex filaments, etc. Outsourced staple 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 make use of the excellent physical properties of the core yarn chemical fiber filament and the performance and surface characteristics of the outer staple fiber to give full play to the strengths of the two fibers and make up for their deficiencies. For example, polyester-cotton core-spun yarn can give full play to the advantages of polyester filament, which is refreshing, crepe-resistant, easy to wash and quick-dry, and at the same time, it can give full play to the advantages of 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, 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, and use the different chemical properties of chemical fiber filaments and outer fibers.
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, which can be used to produce student uniforms, work clothes, shirts, bathrobe fabrics, skirt fabrics, bed sheets and decorative fabrics. An important development of core-spun yarns in recent years is the use of core-spun yarns with polyester cores covered with viscose, viscose and linen or cotton and viscose blends in women's clothing fabrics, as well as cotton and silk or cotton and wool. Blended covered corespun yarns, these products are very popular.
