Bamboo Shade Fabric

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-molecule 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-molecule 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0022] The bamboo shade fabric of present invention is primarily composed of a plurality of bamboo filaments 1 woven in a weft and warp fashion, i.e. having vertical and horizontal filaments woven together. FIG. 1 shows the weaving in a weft and warp fashion, but is more aptly for the second embodiment of two filaments as a unit, discussed later. No new figure is needed as FIG. 1 is more than sufficient to enable the practice of said weft and warp weaving.

[0023] Each of the filament 1 is composed of a high-molecule single bamboo thread 3 inside a layer of coating 4 wherein the layer of coating 4 and is made to be thicker at a node section 2 at the middle portion of the filament 1, with the thickness tapering off towards two distal points of the high-molecule single bamboo thread 3. The layer of coating 4 will add to the physical and/or mechanical strength of filament 1, and thus the bamboo fabric overall.

[0024] The node section 2 has a preferred diameter of between 0.3 mm and 5 mm, and the high-molecule single bamboo thread 3 has a preferred diameter of between 0.15 mm and 2.0 mm.

[0025] Additionally, the layer of coating 4 uses PVC material.

[0026] The layer of coating 4 can optionally add UV-absorbent materials. Commercially available UV-absorbent materials can be used. Such materials include, but not limited to, benzotriazole, benzophenone, etc., that can be used on different types of PVC or plastics products.

[0027] With or without the UV-absorbent materials, the layer of coating 4 is made to be between 0.1 mm and 3 mm.

[0028] The length of the middle node section 2 is made to be between 10 mm and 1,000 mm.

[0029] Additionally, glue can be applied to the junction points of the horizontal and vertical filaments when woven together.

[0030] In another embodiment of present invention, two filaments 1 are put together as a single unit, so that a plurality of such dual-filament units are woven in a weft and warp fashion, as shown in FIG. 1.

[0031] The construction is the same as the first embodiment where each of the filament 1 is composed of a high-molecule single bamboo thread 3 inside a layer of coating 4 wherein the layer of coating 4 is made to be thicker at a middle node section 2, with the thickness tapering off towards two distal points of the high-molecule single bamboo thread 3.

[0032] The layer of coating uses the PVC materials as already described.

[0033] The addition of UV-absorbent materials, as introduced in the first embodiment, applies equally to the 2-filament embodiment.

[0034] The same construction for the thickness of the layer of coating 4 is the same: be between 0.1 mm and 0.3 mm. The same construction for the length of the middle node section 2 is the same: between 10 mm and 1,000 mm.

[0035] The invention of the bamboo fabric shade, as disclosed herein, will aid in the reduction of light pollution for home decoration purposes.

[0036] Applicant noted that the description and disclosure made herein illustrated the preferred embodiments of the invention and are not meant to limit the scope of the applicant's rights. Variations and alterations may be employed for yet additional embodiments without departing from the scope of the invention herein.
