Double-Wall Dropstitch

DWF(Double Wall Fabric), which it is with 3D hollow structure. By using 3D weaving technology, the two layers of base fabric are connected together with the pile yarns. Due to the different ways of the pile yarns, the surface shape can be a pattern like wavy (W shape), starry, linear, and other surface shapes can be customized such as X shapes. Since each pile yarn thread has got the same length which define the maximum distance between the two base fabrics, DWF keeping of the desired shape of the hollow body - a dimensionally-stable surface, smooth and excellent flexibility.
