What is "Covered yarn" - Definition & Explanation
Covered yarn

Covered yarn is a specialized type of yarn used in the textile industry that consists of a core yarn wrapped or "covered" with another yarn or filament. It is created by encasing the core yarn with one or more wrapping threads or filaments, forming a protective layer around the core. This wrapping can be done using various techniques, including twisting, wrapping, or braiding.

Covered yarn is widely used in the production of a variety of textiles, including hosiery, lingerie, activewear, and technical fabrics. The choice of core yarn and wrapping material depends on the desired characteristics of the final fabric, such as stretchability, strength, durability, and appearance.

Types of Covered Yarn

There are several types of covered yarn, each with its unique characteristics and applications:

  1. Spandex Covered Yarn: In this type, a core yarn, often made of polyester or nylon, is covered with spandex or elastane. Spandex-covered yarns provide excellent stretch and recovery properties, making them suitable for stretchable fabrics like sportswear, swimwear, and intimate apparel.
  2. Rubber Covered Yarn: Rubber-covered yarns feature a rubber filament or thread as the covering material. These yarns offer superior elasticity and are commonly used in applications where high stretchability is required, such as in elastic bands, waistbands, and socks.
  3. Texturized Covered Yarn: Texturized covered yarns are created by covering a core yarn with a textured or crimped filament. This type of covered yarn adds bulk and texture to fabrics, enhancing their aesthetic appeal. It is often used in upholstery, home furnishings, and decorative textiles.
  4. Metallic Covered Yarn: Metallic covered yarns consist of a core yarn covered with a metallic or metallized thread. These yarns add a shimmering or reflective effect to fabrics, making them suitable for decorative purposes, festive wear, and fashion accessories.
  5. Core-Spun Covered Yarn: Core-spun covered yarns have a core made of a different fiber, such as cotton or polyester, which is covered with a wrapping thread. This type combines the characteristics of the core and wrapping material, offering a blend of comfort, strength, and other desired properties.

  2. Handle covered yarn gently to prevent snagging or tangling, which can cause damage to the wrapping material or affect the integrity of the core yarn.
  3. Follow the care instructions provided by the manufacturer to maintain the yarn's quality and appearance. Some covered yarns may require specific washing or drying methods.
  4. When using covered yarn in sewing or knitting projects, choose appropriate needles or hooks that won't snag or split the yarn.
