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 by maximizing the strengths and avoiding the weaknesses. Compared with spun yarn, general filament yarn has the advantages of uniform evenness, high strength, good elongation, and good elasticity. It is suitable for the backbone of core-spun yarn, so that it can give full play to the high strength, good elasticity and special filament function of the yarn. Features. 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.
Core-spun yarn for sewing,
Core-spun yarn for burnt-out cloth,
Stretch fabrics (including knitted fabrics, woven fabrics) core-spun yarn,
Functional, high-performance fabric core-spun yarn, etc.
Fancy core-spun yarn (such as hollow core-spun yarn, color core-spun yarn, Syrofil core-spun yarn, slub core-spun yarn, etc.)
Rigid core-spun yarn: polyester, acrylic, vinylon (including water-soluble vinylon), nylon, etc.
Elastic core-spun yarn: spandex, PTT fiber, PBT fiber, etc. Spandex is the most widely used.
Usually cotton, wool, silk, hemp (including ramie, linen, hemp, etc.), colored cotton and other natural fibers;
Viscose fiber, MODAL, TENCEL, soybean fiber, milk fiber, bamboo pulp fiber, polyester fiber, acrylic fiber and various colored chemical fibers can be used as the covering fiber of core-spun yarn.
Ring spinning, rotor spinning, friction spinning, air-jet spinning, etc. can be equipped with core-spun yarn spinning devices to produce various core-spun yarns.
The core-spun yarn products are very wide, and various raw material natural fibers, traditional chemical fibers, new fibers, functional fibers, high-performance fibers, etc. can be applied. The products are related to various fields of clothing and home decoration industry, involving civil and military industries, and are in continuous development, with promising prospects.
