Key Features
- Fine Denier Core Structure Stability
The yarn uses a 20D continuous filament core, which maintains stable linear density under controlled tension during winding. This reduces diameter fluctuation and supports uniform feeding behavior in fine-gauge knitting systems.
- Controlled Covered Yarn Construction
The outer fiber layer is wrapped around the core through a regulated covering process. This structure ensures even fiber distribution around the filament core, reducing direct metal contact and maintaining stable surface condition during machine operation.
- Stable Processing in Fine Gauge Machines
The yarn is designed for high-density knitting environments, where it passes through guide rollers and needle zones under continuous tension. The structure helps maintain stable loop formation and reduces yarn deviation during high-speed feeding.
- Consistent Mechanical Behavior in Production
Through controlled extrusion and covering processes, the yarn maintains stable tensile response and elongation behavior across production batches, ensuring consistent performance in repeated knitting and weaving cycles.
Quality Control System
20D Filament Core Control
The 20D filament core is monitored during extrusion and winding to control linear density deviation and filament continuity. Tension regulation is applied throughout forming to maintain stable elongation behavior and consistent feeding performance in fine-gauge knitting systems.
01
Covering Structure Inspection
The outer covering layer is inspected for wrapping density, coverage continuity, and surface consistency. This ensures the core is fully enclosed and reduces friction contact between the filament and machine guide components during high-speed operation.
02
Twist & Structural Alignment Control
The yarn structure is controlled through twist insertion and filament alignment regulation, ensuring the covering layer remains evenly distributed around the 20D core. This reduces local stress concentration and prevents uneven yarn deformation during continuous processing.
03
Batch Consistency Verification
Batch comparison is conducted through tensile extension and recovery response testing, ensuring consistent mechanical behavior across production lots. Key parameters such as elongation curve and load response are kept within controlled tolerance ranges for industrial use.

FAQ
What is 20D Covered Yarn?
It is a yarn structure with a 20D continuous filament core wrapped by fibers such as nylon, polyester, or cotton. The covering layer controls surface friction and protects the fine filament core during textile processing.
Is this yarn suitable for high-speed knitting machines?
Yes, it is designed for continuous feeding in high-speed circular and warp knitting machines, where stable tension and low friction are required at guide and needle contact points.
What affects yarn breakage during production?
Breakage is mainly caused by tension imbalance, excessive friction at guide parts, or improper machine settings, not only material structure. Stable winding and correct tension control reduce this risk.
