At least some embodiments of the present disclosure provide a roofing accessory that includes a radiofrequency radiation shielding non-woven fiber composite material. The radiofrequency shielding non-woven fiber composite material includes a first fiber type that includes a conductive material, where the radiofrequency shielding non-woven fiber composite material has a sufficient amount of the first fiber type so as to result, when the radiofrequency shielding non-woven fiber composite material is positioned on a roof structure, in the radiofrequency shielding non-woven fiber composite material allowing for shielding a predetermined percentage of electromagnetic radiation passing through the roof structure. The radiofrequency shielding non-woven fiber composite material includes a second fiber type that includes a non-conductive material. The first fiber type and the second fiber type are randomly dispersed within the radiofrequency shielding non-woven fiber composite.

Methods of producing a graphic mesh for a solar module are described in which mesh parameters such as warp fiber thickness, weft fiber thickness, and open area size are determined to meet a target energetic efficiency and a chromatic effectiveness. In some embodiments, chromatic effectiveness is based on mesh count, where the mesh count is set according to a distance at which the mesh will be viewed when assembled into the solar module. The mesh has a plurality of warp fibers having the warp fiber thickness and a plurality of weft fibers having the weft fiber thickness, that are interlaced to form a plurality of mesh unit cells. A graphic appearance is printed into the mesh using a coloring substance, where the coloring substance is absorbed by the fiber material to form the graphic mesh.

A woven fabric material including an array of machine direction yarns and cross-machine direction yarns. The array includes larger denier yarns arranged in an alternating pattern with smaller denier yarns in both the machine direction and the cross-machine direction. The array of machine direction yarns and cross-machine direction yarns is arranged to allow water to pass freely through the woven fabric material.

The present invention relates to a composite material comprising a warp-knitted textile panel having wales corresponding to the warp direction and courses corresponding to the weft direction, and first and second opposite faces, said first face being covered with a layer of at least one polymer material. Advantageously, each of said wales includes first stitches formed on every other course with a first yarn, and second stitches formed on every other course with a second yarn, the first and second stitches being alternated on every other course and being in opposite directions. In addition, in the weft direction, the first yarn and the second yarn each form stitches on every other course in alternation.

An artificial turf mat includes a backing and a plurality of protruding artificial grass blades divided into rows and connected to the backing. The mutual distance between successive blades in a row is substantially equal to the distance between adjacent rows and is at least 10 mm. The backing and the blades may be formed and mutually connected by weaving. A method for forming an artificial turf mat includes supplying a backing material, supplying an artificial turf material, forming a backing from the backing material, and connecting blades of the artificial turf material divided into rows to the backing. The blades may be connected to the backing such that their mutual spacing in a row is substantially equal to the mutual distance between adjacent rows and is at least 10 mm.

Polylactide fibers are made from a blend of polylactides. One of the polylactides has a ratio of R-lactic and S-lactic units from 8:92 to 92:8. The second polylactide has a ratio of the R-lactic and S-lactic units of 97:3 or 3:97. The ratio of the R-lactic units to S-lactic units in the blend is from 7:93 to 25:75 or from 75:25 to 93:7. The polylactide fiber contains at least 5 Joules of polylactide crystallites per gram of polylactide resin in the fiber.

An electrically conductive geotextile incorporating graphene and a method of using conductive properties in same to detect anomalies in said textile.

An object of the invention is to provide a cloth having water absorbency, water repellency, and a tendency to float on water, and also a textile product using the cloth. A means of resolution is to obtain a cloth using a fiber A that is not water repellent and a fiber B that is water repellent in a weight ratio (fiber A:fiber B) within a range of 50:50 to 87:13.

The disclosed tarpaulin comprises: a fabric layer, and a resin layer bonded to at least one surface of the fabric layer. The fabric layer comprises: high-density polyethylene (HDPE) multifilament yarns; polypropylene (PP) multifilament yarns arranged to cross the HDPE multifilament yarns; and polyethylene terephthalate (PET) ground yarns binding the HDPE multifilament yarns and the PP multifilament yarns. The resin layer comprises PP and low-density polyethylene (LDPE).

A composite geosynthetic fabric includes a woven fabric and a nonwoven fabric adhered to the woven fabric. The nonwoven fabric includes a plurality of fibers, with each fiber of the plurality of fibers of the nonwoven fabric being about 2 to about 18 denier per filament. A portion of the fibers of the nonwoven fabric extend through the woven fabric and is fused together on a face of the woven fabric that is opposite a nonwoven face side of the woven fabric.
