HKV141B Yarn Covering Machine for Polyester/Nylon Double Covering
HKV141B is designed for double covering production using filament yarns such as polyester or nylon in the 20D–100D range as the covering material. In this process, two covering yarns are wrapped around the core yarn to form double-covered yarn, creating a more balanced yarn structure suitable for elastic textile applications.
The yarn covering machine uses high-speed spindles independently developed by Jinggong and features a newly designed structure that is stable and easy to install. Energy consumption remains low during operation. It is also equipped with a high-performance electronic forming system that improves winding speed and yarn package quality while allowing smoother unwinding in downstream textile processes.
Covered yarn produced by HKV141B is widely used in apparel, knitted fabrics, and various elastic textile materials.

- Spindle
It can be equipped with spindles in either conical or straight designs, depending on production requirements. This flexibility allows the yarn covering machine to adapt to different covering processes.
- Optional Components
Optional wind shields can be installed to reduce air interference between adjacent spindles. This helps lower operating noise, reduce yarn breakage, and support more stable production efficiency.
- Electronic Forming System
Equipped with a high-performance electronic forming system that improves winding speed and yarn package formation, it maintains consistent yarn quality and allows smoother unwinding during downstream processing.
- Safety and Monitoring System
The advanced digital control instruments together with high-quality electrical components monitors operating conditions in real time. Motor overheating protection and dual motor safety protection help maintain safe and stable operation.
