摘要:
A bi-layer, woven geotextile fabric has interwoven first and second layers. The first layer is over and under woven through the second layer in a pre-determined pattern so that the first layer has portions which face a first side of the second layer and portions which face a second side of the second layer. Monofilaments in the warp direction of the first layer have a pre-determined differential heat shrinkage characteristic that is greater than the monofilaments in the warp direction of the second layer. Closed cells defined by the pattern of the over and under weave are disposed on the first and second sides of the second layer. Shrinkage of the monofilaments in the warp direction of the first layer provide for a separation of a portion of the second layer from the first layer at the cells.

The present invention is directed to a monofilament, a yarn, a tape, or a staple fiber, each having 1 to 12,000 Denier per filament, a draw ratio of 2.5:1 to 25:1, and made of a polypropylene composition of a melt blended admixture of about 93% by weight of polypropylene, about 5% by weight of a polypropylene/ethylene copolymer, and about 2 wt. % of an additive. Also, a process for preparing the monofilament, yarn, tape, or staple fiber is disclosed.

A woven geosynthetic fabric is disclosed having a first weft yarn, a second weft yarn, and a stuffer pick woven in the weft direction of the fabric. A warp yarn interweaves the first and second weft yarns and the stuffer pick. The first weft yarn and the second weft yarn having different cross-sectional shapes. At least a portion of the fabric has a plurality of weft yarn sets with stuffer picks respectively disposed and woven between the weft yarn sets. Each weft yarn set has two first weft yarns and two second weft yarns. One of the two first weft yarns is adjacent one of the two second weft yarns and stacked on the other second weft yarn. The adjacent second weft yarn is stacked on the other first weft yarn.

Embodiments of the invention can provide systems and methods for providing an artificial grass system. One embodiment of the invention can provide an artificial grass system with a woven tubular-shaped fabric and tufted artificial turf yarn. For example, the woven tubular-shaped fabric can be made from at least two types of yarn with different shrink characteristics. Various embodiments of the invention can provide improved drainage, shock absorbency, load displacement, and dimensional stability characteristics for an artificial grass or turf system.

摘要:
Described herein is a monolithic three-dimensional composite having a three-dimensional layer impregnated with an outer layer of polyurea, polyurethane, or a blend thereof. In one aspect the three-dimensional layer is woven fabric of a plain 4-layer tubular weave. Optionally, the outer layer has a three-dimensional relief to simulate three-dimensional structures.
摘要:
A double layer woven fabric for use in various applications, including recreational applications such as pool covers. The fabric is formed by two layers of yarns secured together. At least one layer (and, in one embodiment, both layers) of yarns comprises at least two types of yarn of differing geometrical shapes that are preferably positioned alternately across the fabric. The yarns of one shape help to block sunlight while the yarns of the other shape help to ensure that open channels are formed through the fabric for water flow.

摘要:
A woven fabric (10) comprising at least one raveling-prone weave section (12) surrounded by raveling-resistant weave (14) such that said raveling-resistant weave defines the shape of said at least one raveling-prone weave section. A method for creating a woven fabric having a plurality of raveling-prone weave sections, each surrounded by a perimeter of raveling-resistant weave, comprises programming a desired weave pattern into a dobby to weave the raveling-prone weave sections of the fabric in a prescribed pattern and change the weave to that of the raveling-resistant weave when the desired length of those raveling-prone weave sections is reached; drawing warp ends corresponding to the raveling-prone weave sections on harness frames (62) separate from those harness frames associated with warp ends corresponding to the raveling-resistant weave such that the warp ends of the raveling-prone weave sections can be independently raised or lowered by their associated harness frames; weaving fabric according to the prescribed pattern in the dobby; and providing raveling-resistant weave in the warp direction by independently raising and lowering warp ends associated with the raveling-resistant weave.
