Spacer Fabric Production on Double Needle Bar Raschel
topic
Double needle bar Raschel machines produce three-dimensional spacer fabrics by knitting simultaneously on two parallel needle bars with pile guide bars connecting the two fabric faces through monofilament pile yarns that maintain a defined separation of 2 to 30 millimetres between face and back fabric layers, creating compressible sandwich structures used in mattress ticking, shoe insoles, medical cushioning, and technical composite applications.
Role
Produces warp knitted spacer fabrics whose three-dimensional sandwich structure provides cushioning, ventilation, and compression resistance properties unachievable in single-face knitted fabrics, enabling spacer fabric applications in performance footwear, medical pressure distribution devices, automotive seating, and composites where the combination of surface fabric properties and controlled spacer layer compression behaviour is functionally essential.
