Key Performance Characteristics
- Recycled Filament Integration
Recycled filament is used as the covering component, with recycled content and filament specifications controlled according to the defined yarn construction and production requirements.
- Single Covered Yarn Structure
A single layer of recycled filament is wrapped around the elastic core, creating a controlled outer covering and defined yarn diameter for subsequent textile processing.
- Controlled Tensile & Elongation Behavior
Tensile strength and elongation are evaluated according to the selected recycled filament and finished-yarn specification rather than assumed to be identical to virgin filament.
- Surface & Yarn Uniformity
Filament fineness, covering tension and winding conditions are controlled to maintain a consistent outer surface and reduce localized variation along the yarn.
- Elastic Core Performance
The Spandex/Elastane core provides stretch and recovery characteristics, while the actual elastic performance depends on core denier, covering construction and finished-yarn specifications.
- Traceable Recycled Material
Recycled material can be managed according to defined material specifications and applicable certification requirements, supporting clearer identification of the recycled component throughout yarn production.
Recycled Single Covered Yarn Quality Control
- Recycled Material Verification
Recycled filament specifications, material information and applicable certification requirements are checked before production to ensure the selected material matches the approved yarn construction.
- Covering Process Control
Core positioning, covering tension and filament distribution are monitored during single covering to control yarn structure, diameter variation and outer-surface condition.
- Finished Yarn Testing
Finished yarn can be evaluated for denier, tensile strength, elongation, elastic recovery and other agreed technical parameters according to the product specification.
- Package & Batch Inspection
Cone winding, yarn appearance and package condition are inspected before shipment, with batch information maintained for production identification and quality tracking.
FAQ
What is Recycled Single Covered Yarn used for?
It can be used in hosiery, socks, seamless garments, sportswear, knitted fabrics and other textile products where a covered yarn with an elastic core is required.
Does the recycled material determine the elasticity of the yarn?
Not directly. Elasticity is mainly related to the Spandex/Elastane core and yarn construction, while the recycled covering filament affects the outer layer and overall yarn behavior.
Can Recycled Single Covered Yarn be used for knitting?
Yes. Its suitability for knitting depends on the selected recycled filament, yarn specification, covering tension and the requirements of the specific knitting process.
How should I select the yarn denier for my fabric?
The appropriate denier depends on fabric construction, required thickness, stretch characteristics, machine settings and end-use requirements. KJS can recommend a specification based on the target fabric structure.
