  • Patent number: 11939705
    Abstract: Present invention teaches a bamboo fabric shade that is woven in a weft and warp fashion from a plurality of bamboo filaments. An alternative embodiment of dual bamboo filaments as a single unit for the weaving is done in a similar fashion. Each bamboo filament has a high molecular mass bamboo thread inside a layer of coating wherein the coating is made to be thicker at a middle node section with the thickness tapering off towards the two distal ends of the high molecular mass bamboo thread. The coating uses PVC material, with optional addition of UV-absorbent materials. Such construction of the bamboo fabric adds to the reduction of light pollution when used for home decoration purposes.
