HKV141A Spandex Covered Yarn Machine Single/Double Covering
Designed for covered yarn production, HKV141A produces spandex covered yarn by wrapping filament yarns such as polyester or nylon around a spandex core. The spandex covering machine is suitable for fine denier yarn processing. Typical configurations include 20D spandex as the core yarn covered with 12D polyester or nylon filament, or 20D spandex covered with 30D polyester or nylon filament.
It operates with high-speed spindles reaching up to 22,000 rpm, helping maintain stable production while supporting energy-efficient operation. The spandex covered yarn machine also adopts a high-strength bobbin holder together with an anti-slip spandex feeding unit. A yarn feeding pressure roller keeps yarn tension stable, allowing the covering process to maintain consistent twist and uniform yarn quality.
The yarn produced is widely used in knitted textile products such as hosiery, seamless underwear, and other elastic fabric applications.

High-Speed SpindleEquipped with a newly developed high-speed spindles, the spindle can reach a maximum no-load speed of up to 22,000 rpm, allowing the covering machine to operate at high speed while maintaining lower energy consumption and long service life.
-
Electronic Forming SystemIt is equipped with a high-performance electronic forming system that supports faster winding formation. This system helps improve yarn package quality and makes unwinding smoother during downstream textile processing.
-
Optional Full Servo Control System
An optional full servo control system is available, making process parameter settings easier and more precise. The user-friendly control design also helps operators adjust production conditions more efficiently.
-
Safety and Monitoring System
Advanced electronic components, including digital control devices, allow the yarn covering machine to monitor operating data in real time. Motor overheating protection and dual motor safety protection are also included to support safe and stable machine operation.
