Core-spun yarn refers to a composite yarn composed of core yarn and sheath yarn; generally, filaments are used as core yarns, and staple fibers are sheathed fibers—sheath yarns.
Through the combination of outsourcing fiber and core yarn, they can play their respective advantages, make up for the shortcomings of both sides, and optimize the structure and characteristics of the yarn.
It can be seen that compared with spun yarn, general filament yarn has the advantages of uniform evenness, high strength, good elongation, and good elasticity. It is suitable as the backbone of core-spun yarn to make full use of the high strength, good elasticity and special characteristics of the yarn. Features such as filament function.
Staple fiber is the outer fiber of core-spun yarn, which can give full play to the function and appearance effect of the fiber, such as the brilliance and beauty of the new fiber, the fiber’s excellent water absorption, moisture absorption, heat resistance, warmth retention, softness, and pilling resistance. And other excellent specialties.
The combination of the two can produce core-spun yarns that are incomparable to ordinary spun yarns and filaments. Such as elastic core-spun yarn, high-strength, high-modulus, high-temperature-resistant sewing core-spun yarn, burnt-out core-spun yarn, functional hollow core-spun yarn, high-function core-spun yarn, etc.
In addition, the combination of the two fibers and the core-spun are also often beneficial to spinnability and weaveability. For example, the stainless steel conductive fiber cannot be spun due to open flames, but it can be used as a core yarn to make a core-spun yarn. Shield electromagnetic wave function. The weaveability of core-spun yarns is generally better than that of filaments. The core-spun yarn is equipped with a suitable blending ratio of the two fibers, which can also save raw material costs and spinning costs.
For example: polyester cotton core-spun yarn
It can give full play to the advantages of polyester filaments that are cool, crepe-resistant, easy to wash and dry, and at the same time, the outer cotton fiber has the advantages of good moisture absorption, low static electricity, and resistance to fluffing 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.
