Understanding Double Covered Yarn
Double covering yarn is a type of yarn where a core material, such as spandex or elastane, is wrapped with two layers of covering fibers. The inner core offers elasticity, while the outer coverings provide strength, durability, and comfort. This makes it a very versatile yarn, used to create stretchy and resilient fabrics commonly found in sportswear, hosiery, and medical textiles. By structure, it offers the yarn better resistance to abrasion while keeping the flexibility and smoothness of the covering.
What is Double Covered Yarn?
The double-covered yarn is a special type of yarn made with two layers of covering fibers over an elastic core, commonly known as a spandex or elastane core. The fibers of the inner covering layer and those of the outer covering layer, usually made of other materials such as nylon, polyester, and cotton, are wound around the core in opposite directions.
Having two layers of coverings results in increased durability, strength, and uniformity for the yarn. It is primarily used in applications requiring elastic with resin, such as activewear, compression garments, hosiery, and medical textiles. Double-covered yarn marries elasticity with a soft, smooth exterior to provide something equally functional and comfortable, and, in that way, feels like a widely cherished textile creation.
How is Double Covered Yarn Made?
Double-covered yarn is produced through a complex process that involves forming two layers of covering fibers around a central core. First, the core material is selected, typically an elastic fiber such as spandex or rubber, depending on whether stretch and flexibility are desired.
The first covering yarn layer will be wrapped around the core in one direction, most likely using high-speed covering machines capable of precision. The second layer, however, will be wrapped in the opposite direction, ensuring thorough coverage and a balanced structure.
Newer technologies enable the control of tension on the fiber during wrapping and the evenness of the wrapping process, resulting in a more consistent product. Other advancements in modern double-covered yarn production solve performance factors, such as moisture-wicking, heat-resistant qualities, and durability, making the yarn fit for a variety of applications.
