Elastic Recovery Behavior
- Spandex Core Recovery Force
The 20D spandex core provides the primary elastic force, enabling the yarn to return toward its original length after stretching and ensuring reliable recovery performance in textile applications.
- Controlled Stretch–Recovery Cycle
The yarn is engineered to maintain a controlled stretch–recovery behavior, allowing consistent elongation under load and stable rebound after tension release during repeated use.
- Stable Elastic Response
The SCY structure helps stabilize elastic response during deformation cycles, ensuring uniform behavior across different knitting conditions and reducing irregular tension variations.

Quality Control System
20D Spandex Inspection
The spandex core is strictly checked for denier accuracy and elasticity performance to ensure consistent stretch and recovery characteristics.
01
70D Nylon Covering Uniformity
The nylon covering layer is monitored for uniform filament distribution, ensuring stable yarn structure and smooth processing performance.
02
Elongation Testing
Each batch undergoes controlled elongation testing to verify stretching behavior under defined tensile conditions.
03
Recovery Consistency Control
Recovery performance is tested across production batches to ensure stable elastic response and consistent quality in end-use applications.

FAQ
How does SCY 2070 achieve elastic recovery?
The 20D spandex core stores deformation energy and releases recovery force, while the nylon covering stabilizes yarn shape during stretching.
Will elasticity decrease after repeated use?
The yarn is designed for long-term stretch–recovery cycles, but extreme over-stretching or improper processing conditions may affect durability.
Can elasticity be customized?
Yes. Elastic performance can be adjusted by modifying spandex denier, covering density, and yarn structure design.
What affects yarn performance during knitting?
Machine tension, feeding speed, guide friction, and knitting gauge can all influence elasticity stability and fabric uniformity.
