Knitting Process Stability
- Smooth Loop Formation
The yarn structure allows consistent loop formation in circular knitting and hosiery machines, helping achieve uniform fabric construction and stable elasticity distribution.
- Guide Friction Control
The polyester covering layer reduces direct friction on the spandex core, ensuring smoother passage through guides, needles, and machine contact points.

- Stable Machine Tension Response
The yarn maintains stable behavior under cyclic machine tension, helping minimize yarn stress variation during continuous production.
- High-Speed Knitting Compatibility
SCY 2070 is suitable for high-speed knitting systems, supporting long-run production with reduced risk of yarn breakage and improved processing stability.

FAQ
What is the structure of SCY 2070?
It consists of a 20D spandex core wrapped with 70D polyester filament in a single covering structure (SCY).
What is the advantage of using polyester as covering material?
Polyester provides better dimensional stability, smoother surface performance, and reduced friction during knitting, improving processing efficiency.
Is SCY 2070 suitable for high-speed knitting machines?
Yes. It supports continuous feeding, stable loop formation, and smooth operation in high-speed circular knitting systems.
How does SCY 2070 achieve elasticity?
The spandex core provides stretch and recovery force, while the polyester covering layer stabilizes yarn structure during deformation cycles.
