RD7 Machine – RD7-EL Double Needle Bar Raschel Machine for 3D Spacer Fabric
Product Description
What is an RD7 Machine?
An RD7 machine is a double-needle bar Raschel warp knitting machine designed for producing three-dimensional spacer fabrics and air mesh textiles.
The A-ZEN RD7-EL uses two needle bars and 7 guide bars to produce breathable three-dimensional warp-knitted fabrics with different structures and spacer effects.
RD7 machines are commonly used for producing:
3D spacer fabrics
Air mesh textiles
Shoe upper fabrics
Mattress spacer textiles
Automotive interior textiles
Backpack spacer fabrics
Technical mesh fabrics
The final fabric structure depends on the yarn type, guide bar lapping, machine configuration and production requirements.
KEY FEATURES OF THE A-ZEN RD7-EL
1. 7 Guide Bars for Flexible Fabric Construction
The machine is equipped with 7 guide bars, providing flexibility for developing different spacer fabric structures and mesh designs.
The guide bar configuration supports the production of a wide range of technical spacer fabrics according to yarn selection and knitting requirements.
