The base fabric of the warp knitted light box fabric is woven on a double-axis Warp Knitting Machine, mainly RS2(3) MSU S/EMS type Raschel type Warp knitting machine and Copcent ra HS2ΟST type Trico warp knitting machine two. In practice, the RS2MSU S warp knitting machine can be used for knitting, the general choice of machine numbers E12 to 24, mostly with E18.

The warp knitted fabric is processed by the double-axis warp knitting machine, due to good mechanical properties, simple process, short process, fast and low cost, etc., as a flexible light box base cloth material has been used in large quantities. China's current production of warp knitting light box fabric is quite large. Warp-knitted bi-axial light box fabric belongs to the fiber-reinforced composite material, the base fabric is generally bi-axial warp-knitted fabric, the substrate is mostly polyvinyl chloride (PVC) resin material, its main production process is raw materials - warping - weaving - finishing (calendaring lamination or coating). model RS2MSU S; E18; the number of combs used 2; width 541 cm (213"); machine speed: 1000 r/min.


In this process, the warp lining comb FB3 does not move laterally, but only smoothly places the warp yarn pad between the needles, while the ground comb uses a handful of warp flat pads to bind the warp lining yarn layer and the weft lining yarn layer.
