Raschel Double Needle Bar Jacquard Warp Knitting Machine RDJ4/2

The advantage of warp-knitted seamless fabrics is that it is produced in a single sequence without any seam process after the knitting work.

Besides, the high productivity and shape flexibility outweigh other knitting machines.

Lastly, thanks to the piezo-jacquard technology, various patterns are available on the RDJ4/2 machine.

To those who produce seamless fabrics from the circular knitting machine, RDJ4/2 shows its strong merit in the effective rate of finished fabrics, because the yarn does not run if it breaks off, and the fabric will bring a comfortable skin feeling to its user.

Nowadays, the piezo-jacquard technology is used on other double-needle bar machine models, such as RDJ5/1, RDJ6/1, RDJ7/1, and RDJ6/2.
