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.

CF=CF.sub.T+CF.sub.W where CF represents the total cover factor of the warp and the weft; CF.sub.T represents a cover factor of the warp; and CF.sub.W represents the cover factor of the weft.

The present invention provides a water-repellent woven or knitted article that overcomes the problems of the related art and exhibits water-repellent properties and is excellent in abrasion resistance and durability. The water-repellent woven or knitted article of the present invention is a woven or knitted article subjected to a water repellent treatment using a water repellent having a perfluorooctanoic acid (PFOA) concentration of 5 ng/g or less, wherein the woven or knitted article includes, as constituent fibers, fibers having a transverse cross-sectional shape, each fiber has a plurality of grooves at an outer circumference of the transverse cross section, each groove has a wide part, and a size of the grooves in the fibers satisfies the following Formulae (Formula 1) and (Formula 2):

w2/w1≥1.3  (Formula 1)

0.15≤h/d≤0.25  (Formula 2) where w1 represents a groove entrance width, w2 represents a groove wide part width, h represents a groove depth, and d represents a diameter of the fiber, a droplet contact angle between the woven or knitted article and water is 135° or more after 20 times of washing in accordance with a method of JIS L 0217 103 and a water repellency is grade 4 or more in accordance with a spray method of JIS L 1092.

A glass cloth including warp yarns and weft yarns that are glass yarns each formed by bundling 30 to 44 glass filaments each having a circle-equivalent diameter of 3.0 to 4.4 μm, wherein the weaving density of the warp yarns and the weft yarns is 85 to 125 yarns/25 mm, at least either of the warp yarn and the weft yarn is a flat glass yarn formed of flat glass filaments, the weaving density thereof is less than 100 yarns/25 mm, the major axis DL of the flat glass filament is 3.3 to 6.0 μm, the minor axis DS is 2.0 to 3.9 μm, the number of twists T of each of the flat glass yarns is 0.70 twists/25 mm or less, and the number of the flat glass filaments F constituting each of the flat glass yarns, T, DL, and DS satisfy the following expression:

[00001]$89.0\le F\times \left(\mathrm{DL}\times \left(1-T^{1/2}\right)+\mathrm{DS}\times T^{1/2}\right)/\left(\mathrm{DL}/\mathrm{DS}\right)\le 129.0.$

Fabrics containing hydrophilic expanded polytetrafluoroethylene (ePTFE) fibers and at least one non-ePTFE fiber are provided. The fabric provides a combination of high breathability and controlled moisture management. In exemplary embodiments, the fabric may be a woven, knit, or fleece fabric. The fabrics contain at least 15% ePTFE fibers based on the final fabric. The hydrophilic ePTFE fibers in the fabrics may be used to control moisture such as water vapor, liquid water, or sweat within the fabric by storing the moisture within the hydrophilic ePTFE fiber network. Also, little to none of the moisture remains on the outside of the hydrophilic ePTFE fibers, making the fabric feel dry even where there is moisture therein. A polymer membrane and/or a textile may be laminated to the fabric to produce a laminated article.

A method of making a yarn is disclosed. A plurality of fibers is obtained by: preparing a slurry of polymer mixed with water insoluble nanoparticles of electrolytic copper, and extruding the slurry through a spinneret that includes a plurality of holes which impart a generally “X”-shaped cross-section to the plurality of fibers. The plurality of fibers are spun together to form the yarn.

An item such as a fabric-based item may have a layer of fabric such as a layer of woven fabric. The fabric layer may include warp and weft strands. The fabric may cover keys in a keyboard or may be used in forming other structures in the fabric-based item. Each key may have an illuminated key label. Portions of the fabric may be processed by pressing heated protrusions on a textured mold into polymer optical fibers in the fabric. The protrusions form corresponding light-scattering recesses in cladding portions of the optical fibers. Light-emitting diodes or other light sources may be coupled to respective end surfaces of the optical fibers. The light-emitting diodes emit light that is emitted from the thermally imprinted light-emitting regions formed by pressing the heated protrusions into the optical fibers.
