Efficient Fabric Opening and Smooth Winding
The pneumatic opening width system ensures the fabric is automatically and evenly spread during knitting, reducing creases and improving winding quality—ideal for high-standard dyeing and finishing processes.
Stable Double-Side Knitting Performance
Designed for producing double jersey fabrics, the machine delivers high-speed, balanced knitting with excellent fabric stability, making it suitable for heavy-weight and elastic materials like rib, interlock, and spacer fabrics

  • Machine Type
    Double‑Side (Interlock/Double Jersey) circular knitting machine with pneumatic open‑width take‑up and slitting system – optimized for fabric flattening and clean edge finishing. 

  • Cylinder Diameter
    34″ (≈ 863 mm) – standard body‑size diameter common in this class. 

  • Gauge
    28G (28 needles per inch) – medium‑fine gauge producing smooth, drapey interlock fabric.

  • Feeders
    72 feeders – balanced for 28G, providing even yarn feeding and high efficiency. 

  • Needle Count
    ~2,136 needles total (single‑side 1,068; double‑side counts ~2× needles).

  • Motor & Drive
    Typically driven by 5.5–7.5 kW (~7.5–10 HP) (~380 V 3‑phase) motor via inverter for speed control. 

  • Knitting Speed
    Operates between 15–30 RPM, depending on yarn, gauge, and fabric style. 

  • Fabric Take‑Up
    Pneumatic open‑width take‑up maintains width and eliminates curl, paired with slitter for clean raw edge. 

  • Frame & Precision
    Heavy-duty steel chassis, oil-immersed needle bed, Japanese stainless cylinder; high-precision cams, electronic or air lubricators. 

  • Control & Safety
    Equipped with RPM counters, broken-needle sensors, positive feeders, frequency inverter, dust/fan protection. 


Fabric Types Produced

  1. Classic Interlock/Double Jersey
    Smooth, reversible, no curl, ideal for T-shirts, underwear, sportswear. 

  2. Rib & Twill Structures
    Achieved with adjustable cam tracks for 1×1, 2×2 rib, piqué, twill, waffle textures. 

  3. Air-layer/Bubble Fabrics
    Volumized textures like air-layer, bubble, and pique, generated by cam settings. 

  4. High-Pile / Velvets (Optional Jacquard Add-on)
    With jacquard and cutter attachments, can produce loop-cut fleece: coral fleece, velvet, etc. Example images show coral velvet textures.
