Industrial two-layer fabric
09834870 · 2017-12-05 · ·

An industrial two-layer fabric of the contact-yarn binding type without independent binding yarns, at both ends. The upper surface side warp serving as the warp fabric yarn-contact binding yarn is not woven into the upper surface side weft at one or more points of a complete structure, and extends toward the lower surface side instead and is woven into the lower surface side weft at the lower surface side, and then, extends toward the upper surface sides to be woven into other upper surface side weft, while, the lower surface side warp is not woven into the lower surface side weft at a point where the upper surface side warp serving as the warp fabric yarn-contact binding yarn is woven into the lower surface side weft at the lower surface side, and extends toward the upper surface side instead to be woven into the upper surface side weft which is not woven into the upper surface side warp, at the upper surface side, and then extends toward the lower surface side to be woven into other lower surface side weft. The industrial two-layer fabric forms a joint loop by at least one end portion of the warp being turned back at both end portions in its longitudinal direction, and at least a longitudinal yarn in a complete structure includes at least one warp which forms a pair arranged to be opposite to the warp which is turned back for forming the joint loop, and, in a longitudinal structure, the number of knuckles of one of the warps forming the pair is the same as that of the other of the warps forming the pair and distances between said adjacent knuckles are substantially the same.

WOVEN IRRIGATION TUBING, APPARATUS AND METHOD OF MAKING SAME
20220372674 · 2022-11-24 · ·

Woven irrigation tubing comprises 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.

Fiber preform of commingled fiber bundle for overmolding
11673292 · 2023-06-13 · ·

A fiber preform for use in a resin transfer molding or liquid composite molding process and process of making the same are provided. The preform includes a substrate, a fiber bundle arranged on the substrate in a predetermined pattern and attached to the substrate by a plurality of stitches of a thread. The fiber preform is capable of being pre-formed into a three-dimensional shape. The fiber preform along with a sheet of preformed thermoset resin that impregnates at least a portion of the fiber preform forms a composite material. The fiber preform reinforces areas of stress concentration of a core to form a vehicle component.
