What is core spun yarn?

The core spun yarn is usually made of synthetic fiber filament with good strength elasticity as the core wrapped with short fibers such as cotton, wool viscose. The core spun yarn has the excellent properties of both filament core spun yarn wrapped short fiber. The more common core spun yarn is the polyester cotton core spun yarn, which takes the polyester filament as the core yarn wraps the cotton fiber. There are also spandex core spun yarn, which is made of spandex filament as the core yarn other fibers. Knitted fabric jeans made of this core spun yarn can stretch freely fit comfortably when wearing.

Its main purpose is to strengthen the cotton canvas keep the water repellency of the cotton fiber when it swells in the rain. The polyester fiber has tensile elongation, tear resistance shrinkage resistance when it is wet in the rain. At present, the core spun yarn has developed into many types, which can be summed up into three categories: short fiber short fiber core spun yarn, chemical fiber filament short fiber core spun yarn, chemical fiber filament chemical fiber filament core spun yarn. At present, many core spun yarns are a kind of special structure core spun yarn with chemical fiber filament as the core various short fibers as the outer covering. Its core yarn commonly used chemical fiber filament is polyester filament, nylon filament, spandex filament so on. Outsourcing staple fibers are cotton, polyester cotton, polyester, nylon, acrylic wool fibers.

In addition to its special structure, core spun yarn has many advantages. It can make full use of the excellent physical properties of core spun chemical fiber filament the properties surface characteristics of the short fiber, give full play to the advantages of the two fibers make up for their shortcomings. For example, t / C core spun yarn can give full play to the advantages of polyester filament such as crisp, anti crease, easy to wash fast dry, also can give full play to the advantages of outer cotton fiber such as good moisture absorption, less static electricity easy to pilling. The woven fabric is easy to dye finish, comfortable to wear, easy to wash, bright color, beautiful generous. The core spun yarn can only keep improve the performance of the fabric, but also reduce the weight of the fabric, use the different chemical properties of the chemical fiber filament the outer fiber, during the dyeing finishing process of the fabric, a part of the outer fiber is rotted by chemicals, the rotten fabric with three-dimensional pattern effect is made. At present, the core spun yarn with cotton as the skin polyester as the core is widely used, which can be used to produce student clothes, work clothes, shirts, bathrobe fabrics, skirt fabrics, quilt sheets decorative fabrics, etc. In recent years, an important development of core spun yarn is that in women's clothing fabric, core spun yarn with polyester core covered by viscose fiber, viscose fiber flax cotton viscose fiber, core spun yarn covered by cotton silk cotton wool, which are very popular.

According to the different purposes of core spun yarn, the main varieties of core spun yarn are: core spun yarn for clothing fabric, core spun yarn for elastic fabric, core spun yarn for decorative fabric, core spun yarn for sewing thread, etc. There are many spinning methods of core spun yarn: ring spinning, electrostatic spinning, vortex spinning, self twist spinning, etc. At present, China's cotton spinning industry mostly uses cotton ring spinning to spin core spun yarn.
