Covered Spandex Yarn Explained
Covered spandex yarn is a unique textile fiber that combines the stretch and recovery properties of spandex with the durability and abrasion resistance of an outer covering. This innovative yarn structure is designed to provide enhanced performance characteristics compared to regular spandex yarns.
Definition and Production Process
Covered spandex yarn is created by wrapping a core of spandex fiber with a sheath of another textile fiber, such as nylon or polyester. The spandex core provides the essential stretch and elasticity, while the outer covering protects the delicate spandex filament and improves the yarn’s overall durability. The production process involves a specialized technique called “covering” or “air-covering,” where the spandex fiber is fed through a nozzle and wrapped by the sheath fiber using air pressure.
Advantages Over Regular Spandex Yarn
Covered spandex yarn offers several advantages over traditional spandex yarns. The outer covering provides better abrasion resistance, increased tear strength, and improved dimensional stability. This results in enhanced garment and textile longevity, as the covered yarn is less prone to pilling, snagging, and premature wear and tear. Additionally, the covering can improve the yarn’s ability to withstand repeated stretching and compression, making it an ideal choice for activewear, sportswear, and other high-performance applications.
Common Uses in Textiles
Covered spandex yarn finds application in a wide range of textile products, including:
- Activewear and sportswear: The combination of stretch, recovery, and durability makes covered spandex yarn a popular choice for athletic apparel, such as leggings, compression garments, and swimwear.
- Intimate apparel: The improved stretch and shape retention properties of covered spandex yarn are beneficial for lingerie, shapewear, and hosiery.
- Workwear and uniforms: The enhanced abrasion resistance and tear strength of covered spandex yarn make it suitable for use in industrial workwear, uniforms, and other demanding textile applications.
- Denim and bottom-weight fabrics: Covered spandex yarns are often incorporated into denim and other bottom-weight fabrics to provide the desired stretch and recovery without compromising durability.

Difference Between Polyester and Spandex
Polyester and spandex are two distinct textile fibers with different compositions, structures, and performance characteristics. Understanding the key differences between these two fibers is essential for selecting the appropriate material for various textile applications.
Fiber Composition and Structure
Polyester is a synthetic fiber made from the polymerization of ethylene glycol and terephthalic acid, resulting in a thermoplastic polymer. Polyester fibers have a linear, continuous molecular structure that provides strength and durability.
In contrast, spandex (also known as elastane) is a synthetic fiber composed of a polyurethane-polyurea copolymer. Spandex fibers have a segmented molecular structure, with alternating rigid and elastic segments, which gives them their unique stretch and recovery properties.
Performance Characteristics
Polyester is known for its strength, abrasion resistance, and dimensional stability. It also has good wrinkle resistance and quick-drying properties, making it a popular choice for a wide range of textile applications.
Spandex, on the other hand, is renowned for its exceptional stretch, elasticity, and recovery capabilities. Spandex can stretch up to five times its original length and quickly return to its original shape without permanent deformation.
Application Suitability
Polyester is widely used in a variety of textile products, including clothing, home furnishings, and industrial textiles, due to its versatility and cost-effectiveness.
Spandex is primarily used in applications that require stretch and elasticity, such as activewear, intimate apparel, hosiery, and other form-fitting garments. The combination of spandex with other fibers, like polyester or nylon, can enhance the performance and comfort of these textile products.
The choice between polyester and spandex, or a combination of the two, depends on the specific requirements of the textile application, including the desired level of stretch, durability, breathability, and overall performance characteristics.
