Single/Mechanical Covered Yarn (SCY)

Single/Mechanical Covered Yarn (SCY) is a high-quality twisted elastic yarn manufactured by mechanically winding polyester or nylon filament tightly around a stretched spandex core. Different from air-covered yarn, SCY features precise twist structure (TPM), tight wrapping, stable tension and neat yarn appearance. It is widely recognized for producing smooth, firm and wrinkle-resistant fabrics, making it a premium choice for high-standard textile elastic materials.

Product Advantages

Tight Structure & Stable Twist Performance
Formed by professional mechanical twisting process, the outer filament closely covers the spandex core with uniform twist count. The yarn structure does not loosen during weaving or washing, ensuring extremely stable fabric elasticity and dimension stability.

Smooth Surface & Excellent Weavability
Low hairiness, uniform thickness and consistent tension result in very low breakage rate on high-speed looms. It improves production efficiency and reduces defective fabric rates for downstream manufacturers.

Firm & Neat Fabric Appearance
Finished fabrics are flat, crisp, well-shaped and less prone to curling. SCY delivers better shaping effect than ordinary covered yarn, ideal for structured and tailored textile products.

Durable Elasticity & Good Washing Resistance
With compact wrapping structure, the spandex core is well-protected. The yarn maintains steady resilience after repeated stretching and frequent washing, with minimal elasticity fatigue and long service life.

Reliable Batch Consistency & Full Specifications
We supply single-covered and double-covered SCY with complete denier options. All batches feature stable tension, uniform twist and consistent quality, supporting mass export orders and customized requirements.
