Covered Yarn Service
Eachuan International Co., Ltd. provides professional Covered Yarn Service using advanced elastic yarn covering machines imported from Japan and Korea. We source premium polyester and nylon filaments from leading Taiwanese and Korean suppliers to ensure consistent product stability and processing quality.
We produce both Traditional Covered Yarn (SCY/DCY) and Air Covered Yarn (ACY) based on client specifications, widely used in:
- Elastic tapes and intimate apparel
- Socks and home textile fabrics
- Sportswear and medical functional fabrics
Traditional Covered Yarn (SCY / DCY)
- Single Covered Yarn (SCY):
An elastic core yarn wrapped with a single polyester or nylon filament in an S-twist (counterclockwise) or Z-twist (clockwise) direction to create elasticity and uniform texture. - Double Covered Yarn (DCY):
An elastic core yarn covered by two filaments in opposite S and Z directions for enhanced stability, balanced tension, and improved surface evenness.
Typical Combinations:
- Spandex + Polyester: 15D–70D + Polyester 30D–300D
- Spandex + Nylon: 15D–140D + Nylon 13D–140D
Air Covered Yarn (ACY)
Produced by intertwining spandex and polyester or nylon filaments with compressed air, ACY offers better cost efficiency and productivity compared to traditional covering, ideal for high-volume and functional textile applications.
Typical Combinations:
- Spandex + Polyester: 20D–70D + Polyester 30D–600D
- Spandex + Nylon: 20D–70D + Nylon 40D–280D
