11377762 · 2022-07-05 · ·

A novel woven fabric is provided wherein preferably two unidirectional mutually offset and at least partly overlapping layers of tape-like warps interlace with tape-like wefts, at least some being fibrous tapes, that are incorporated individually in either non-overlapping manner or in a mutually offset and overlapping manner relative to other weft tapes. Such a woven fabric is without see-through gaps at the areas/sites encircled by intersecting tape-like warps and wefts, and also delamination resistant. It is particularly suitable for composite material, ballistic mitigation, and similar applications.

Woven geotextile fabrics with integrated geotextile grids or geogrids

A woven geotextile fabric utilizes a plurality of yarns including machine direction field yarns, cross machine direction field yarns, machine direction rib yarns, and cross machine direction rib yarns. The plurality of yarns is integrally woven together. The machine direction rib yarns and the cross machine direction rib yarns cooperatively define an integrated geotextile grid integrally within the woven geotextile fabric. The machine direction field yarns and the cross machine direction field yarns cooperatively define fabric areas in a field of the integrated geotextile grid generally between the machine direction rib yarns and the cross machine direction rib yarns.

Woven Irrigation Tubing, Apparatus and Method of Making Same
20220080685 · 2022-03-17 · ·

Woven irrigation tubing comprising a woven, extrusion coated & laminated tube formed of a high density polyethylene (HDPE) outer layer, a low density polyethylene (LDPE) middle layer and a linear low density polyethylene (LLDPE) inner layer. The finished tubing is treated for ultraviolet resistance. The tubing is tied off at a distal end with a proximal end connected to a pressurized irrigation source. Watering holes are created in the tubing at spaced intervals and the resulting water streams are directed into parallel plowed furrows. The tubing is completely recyclable. The tubing is formed by manufacturing tape for the woven outer tubing cover, stretching the tape along its length to strengthen it, weaving the outer layer from the tape, flattening the woven outer layer, extrusion coating each surface of the outer layer with LDPE, laminating the LLDPE inner layer to the LDPE, reversing and winding the tubing for storage and distribution.

Fabrics containing conformable low density fluoropolymer fiber blends

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.
