Specifications: Spandex Core-Spun Yarn (CSY) is a composite yarn structured with a spandex filament core continuously wrapped by outer staple fibers (such as cotton, viscose, polyester, or nylon). Standard yarn counts include 28S/1, 30S/1, and 40S/1, with core spandex deniers typically ranging from 20D to 70D, combining natural fiber texture with superior elasticity.

Applications: Widely used in premium stretch denim, casual trousers, knitted underwear, sportswear, socks, and woven stretch fabrics. It serves as the ideal raw material for balancing fabric structure and stretch recovery.

Key Advantages:

High Elasticity & Comfort: Delivers excellent stretchability and shape retention, offering a comfortable, non-restrictive fit that resists sagging.
Natural Hand-Feel: The outer fiber fully encases the spandex core, retaining the soft touch, breathability, and moisture absorption of traditional fibers.
Durability & Smooth Processing: The protective core-spun structure shields the inner spandex from damage, minimizing yarn breakage during weaving and providing exceptional wear resistance.
