JapanAbstract: Core-spun yarn, also known as composite yarn or covered yarn, is a new type of yarn composed of two or more fibers. The original core-spun yarn is a staple fiber and staple fiber core-spun yarn developed with cotton fiber as the sheath and polyester spun yarn as the core. Due to its own material, the core wire will be pilling, and the degree of pilling will vary according to the amount of friction.
1. What kind of fabric is core spun yarn?
The core-spun yarn is generally made of synthetic fiber filaments with good strength and elasticity as the core yarn, and the outer cotton, wool, viscose fiber and other short fibers are twisted and spun together. The core spun yarn has the excellent properties of both the filament core yarn and the outer staple fiber. The more common core-spun yarn is polyester-cotton core-spun yarn, which uses polyester filament as the core yarn and wraps cotton fiber. 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, the core-spun yarns that are used more generally are core-spun yarns with a unique structure formed by chemical fiber filaments as the core yarns and outsourcing various short fibers. 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.
2. Will the core-spun yarn pilling?
Core-spun fabrics will pill.
Because the core spun yarn is directly formed on the spinning machine, and the inner yarn core is not exposed, in general, the synthetic fiber filament with good strength and elasticity is used as the core filament of the core spun yarn. Yarn made of cotton, wool or viscose and similar short fibers that are twisted together and woven together. Due to its own material, the core wire will be pilling, and the degree of pilling will vary according to the amount of friction.
