CORE SPUN YARN

Detail
Core Spun Yarn is a special type of yarn where a core fiber is wrapped or covered with another fiber. It combines the desirable properties of both the core and the sheath fibers, making it popular in high-performance and functional textiles.

Definition
Core Spun Yarn is a composite yarn made by wrapping a sheath fiber (usually natural or synthetic staple fibers) around a core filament (usually polyester, spandex, or other synthetic fibers).

Structure
Core (Center): Typically a continuous filament like polyester, nylon, or spandex.
Sheath (Cover): Staple fibers like cotton, rayon, or polyester spun around the core.

Key Characteristics
Feature    Description
Strength  High strength due to filament core
Elasticity  Excellent when core is spandex or elastane
Comfort   Maintains soft feel due to cotton/rayon sheath
Durability        Improved abrasion resistance
Appearance     Looks like spun yarn but performs like filament yarn

Common Fiber Combinations
Core (Filament)       Sheath (Staple Fiber)      Purpose
Spandex   Cotton     Stretch denim, leggings
Polyester Cotton     Sewing threads, uniforms
Nylon       Wool        Durable knitwear
Lycra        Modal/Rayon  Activewear, underwear

Applications
Denim (Stretch Jeans)
Sewing Threads
Sportswear and Activewear
Elastic Fabrics
Medical Textiles (compression garments)



Core-spun yarns are generally classified based on the type of core material and the purpose of the yarn. There are three main types of core-spun yarns:

1. Elastane Core-Spun Yarn (Spandex/Lycra Core)
   Core: Spandex (e.g., Lycra)
   Sheath: Cotton, polyester, or other staple fibers
  Use: Stretchable fabrics like denim, activewear, leggings

2. Filament Core-Spun Yarn
  Core: Continuous filament yarn (e.g., polyester filament, nylon
  Sheath: Staple fibers (e.g., cotton, viscose)
  Use: Sewing threads, technical textiles (high strength & smoothness)

3. Conductive or Functional Core-Spun Yarn
  Core: Metallic or functional filament (e.g., stainless steel, carbon, optical fiber)
  Sheath: Staple fibers or blends
  Use: Smart textiles, e-textiles, medical sensors



 Advantages
  1. Combines comfort and functionality
  2. Stronger than regular spun yarn
  3. Suitable for high-speed sewing
  4. Better dimensional stability
