The pyramidal space can accommodate balls, as shown in Figure 2(a). Without this periodicity of inverted pyramidal space, the plain weave exhibits a planar surface, as shown in Figure 2(b). In a honeycomb woven fabric, the part of the warp yarn underneath a weft float is a warp float. Two layers of floats form a closed internal space. The formed internal space by the parallel yarn floats causes the honeycomb fabric to be believed to be better for transferability and different mechanical properties compared to those of plain fabrics. Owing to the surface pyramidal space and the internal closed space, Na et al.
