Introduction of Core Spun Yarn
The core-spun yarn refers to a composite yarn that is combined by a core yarn and a sheath yarn. Generally, filament is used as the core yarn, and short fiber is used as the outer covering fiber.
Through the combination of the outer fiber and the core yarn, the advantages of each can be brought into play, the deficiencies of both sides can be made up, and the structure and characteristics of the finished yarn can be optimized by taking advantage of strengths and avoiding weaknesses.
Compared with spun yarn, general filament has the advantages of uniform evenness, high strength, good elongation and elasticity. Features.
The staple fiber is the outer fiber of the core-spun yarn, which can give full play to the function and apparent effect of the fiber, such as the beautiful brilliance of the new fiber, and the excellent water absorption, moisture absorption, heat resistance, warmth retention, softness, and anti-pilling of the fiber. and other excellent features.
The combination of the two can produce core spun yarns that are incomparable with general staple yarns and filament yarns. 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-performance core-spun yarn, etc.
In addition, the combination and core covering of the two fibers are often beneficial to spinnability and weaving. For example, stainless steel conductive fibers cannot be spun due to open flames, but they can be used as core yarns to make core-spun yarns, which can also exert electrical conductivity and Shielding electromagnetic wave function. The weavability of the core spun yarn is generally better than that of the filament. The core spun yarn is configured with a suitable blending ratio of the two fibers, which can also save the cost of raw materials and spinning costs.
Taking polyester-cotton core-spun yarn as an example, it can give full play to the advantages of polyester filaments that are crisp, crepe-resistant, easy to wash and quick-dry, and at the same time, take advantage of 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 elegant in appearance. The 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 filaments and outer fibers. Burnt-out fabric with three-dimensional pattern effect, etc.
