Murata VORTEX 870 EX: A Spinning Revolution

Introduction

The VORTEX 870 EX is Murata Machinery’s flagship third-generation air‑jet spinning and winding machine, unveiled at ITMA Barcelona in June 2019. This model sets a new industry benchmark with a top spinning speed of 550 m/min, surpassing the previous VORTEX III 870's 500 m/min.

Innovative Technology

Unlike conventional ring or rotor systems, the VORTEX spinning process generates yarn directly from a sliver using a high-speed air vortex, eliminating the need for roving. This integrated spinning–winding system reduces floor space, cuts labor, and simplifies process flow.

It also incorporates the STS (Spinning Tension Stabilizing) System, stabilizing yarn tension through a friction roller instead of a nip roller, ensuring consistent quality even at ultra-high speeds.

Performance & Specifications

Key specifications include:

• Spinning speed: 300–550 m/min (mechanical range)
• Material compatibility: 100% cotton, cotton/synthetic blends, and synthetic fibers
• Yarn count range: Ne 10–80
• Maximum package diameter: 300 mm
• High ratio 4‑line drafting system with individual back‑roller control
• Key options: Auto doffer, dust box, speed meter, air control panel, VOS control system, splice monitor, package lifter, Polymaster for synthetic fibers

Why It Matters

Yarns produced by VORTEX technology deliver distinctive benefits:

• Low hairiness and a clean appearance, ideal for high-quality apparel
• Superior resistance to pilling and abrasion
• Enhanced moisture absorption, wash fastness, and dimensional stability
• Versatility across broad fiber types and counts—all without changing the spinning unit

Operational Advantages

• Singular process flow: Combines spinning and winding, removing the need for separate roving and winder machines
• High automation and monitoring: Features VOS (Visual On-demand System) for real-time status, MSC (Muratec Spin Clearer) to eject waste fiber, and optional splice monitoring
• Energy efficiency: Optimized motor design and cycle time improvements reduce power consumption and improve sustainability

Applications & Industry Relevance

This machine is widely used for spinning yarns in t-shirts, polo shirts, uniforms, home textiles, and performance wear. It’s also highly effective for blended and synthetic yarns thanks to strong fiber control and tunable spinning components.

Conclusion

The Murata VORTEX 870 EX is a game-changer in textile production—fusing centuries of spinning innovation with today’s demand for speed, consistency, and eco‑efficiency. Whether you’re a mill owner, merchandiser, or engineering manager, this machine represents the cutting edge of yarn technology, offering premium yarn quality at unmatched production rates.
