AI Technical Summary
The high weave density of existing wallpapers results in poor breathability and low moisture removal efficiency.
It adopts a two-layer base structure. The base layer is woven from warp yarns, weft yarns and skein yarns, with high-density and low-density sections alternately. Grooves and connecting grooves are formed on both sides of the base layer. High-count yarns are twisted with warp yarns to form air holes. Chemical fibers and natural fibers are combined to improve breathability and strength.
While maintaining a high weaving density, the wallpaper achieves good breathability and moisture removal, and the production process is simple.
