Performance Built Through Yarn Combination
FENGDA develops covered yarn structures by combining yarn components around required stretch, recovery, processing behavior and end-use performance.
What Is Covered Yarn?
Covered yarn combines yarn components to create a composite structure designed around application requirements. Air Covered Yarn combines yarn components through an air-interlacing process.
Core / Component Yarn
A controlled stage within the overall yarn route.
Covering / Companion Yarn
A controlled stage within the overall yarn route.
Air Interlacing
A controlled stage within the overall yarn route.
Covered Yarn Structure
A controlled stage within the overall yarn route.

Key Performance Considerations
These factors define the questions for technical evaluation. They are not performance guarantees.
Stretch
Evaluate this factor against the intended yarn specification, textile process and end use.
Recovery
Evaluate this factor against the intended yarn specification, textile process and end use.
Core/Covering Structure
Evaluate this factor against the intended yarn specification, textile process and end use.
Processability
Evaluate this factor against the intended yarn specification, textile process and end use.
Application Performance
Evaluate this factor against the intended yarn specification, textile process and end use.

Where Covered Yarn Is Evaluated
Application requirements guide material, construction, coloration and processability decisions.
Socks & Hosiery
Yarn selection should be evaluated against the finished textile structure and performance requirement.
Sportswear & Activewear
Yarn selection should be evaluated against the finished textile structure and performance requirement.
Underwear & Seamless
Yarn selection should be evaluated against the finished textile structure and performance requirement.
Stretch Textile Applications
Yarn selection should be evaluated against the finished textile structure and performance requirement.

Build Around the Application
If an existing entry does not match the requirement, FENGDA can evaluate material, structure, color, processability and application needs as a development brief.
- Application and finished textile
- Performance priorities
- Preferred or current material
- Existing yarn specification, if known
- Color requirement and current production issue
