Dual Covered Yarn

 

• Spandex Denier Inspection

The denier of the spandex core is verified during production to ensure consistency in elastic force generation and elongation behavior.

• Covering Uniformity Control

The inner and outer covering layers are monitored to maintain stable filament distribution and balanced yarn structure throughout the covering process.

• Elongation Testing

Stretch performance is evaluated to verify yarn extension behavior under controlled tensile loading conditions.

• Recovery Consistency Verification

Recovery performance is checked across production batches to ensure consistent elastic response during repeated stretch–recovery cycles.

 

FAQ

What materials can be used as the covering yarn?
The covering layers are commonly made from nylon or polyester filaments, depending on fabric requirements, processing conditions, and end-use applications.

What are the advantages of a dual-cover structure?
The dual-cover design helps reduce yarn torque, improve covering stability, protect the spandex core from friction, and maintain more consistent yarn geometry during textile processing.

Is Dual Covered Yarn suitable for high-speed knitting machines?
Yes. The yarn is designed for continuous feeding, repeated loop formation, and cyclic tension conditions commonly found in circular knitting, hosiery, and seamless garment production.

Can the yarn specification be customized?
Yes. Spandex denier, covering material, covering yarn specification, cone size, and winding configuration can be customized according to production requirements.
