RDJ4/2
A-ZEN
44", 90", 138"
E24, E28
The A-ZEN RDJ4/2 (and RDJ6/2 series) is a state-of-the-art Raschel double needle bar jacquard warp knitting machine engineered for seamless fabric manufacturing.
Utilizing advanced Piezo-Jacquard technology, it delivers high-speed, precise pattern control for producing seamless pantyhose, elastic sportswear, yoga wear, female stockings, wedding gloves, and decorative ribbon trims.
Unlike traditional circular knitting machines, warp-knitted seamless fabrics produced on the RDJ4/2 feature superior fabric stability—yarns do not run or ladder upon breaking—ensuring higher yield rates, ultimate skin comfort, and significant post-processing labor savings.
Piezo-Jacquard Precision: Enables intricate design versatility and independent yarn movement for customized sportswear and technical textiles.
15% Energy Reduction: Integrated EBC (Electronic Beam Controller) yarn let-off system minimizes power consumption and stabilizes yarn tension.
High Productivity & Shape Flexibility: Completes fabric shaping directly on the needle bars, eliminating secondary seam-making operations.
Robust Magnalium Needle Beds: High-tensile magnalium structures combined with premium NSK/INA bearings significantly extend machine service life.
