Publication number: 20100248574Abstract: 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.Type: ApplicationFiled: March 23, 2010Publication date: September 30, 2010Applicant: Nicolon Corporation, doing business as TenCate Geosynthetics North AmericaInventors: Kevin Nelson KING, David Michael JONES, Greg L.

Patent number: 7112283Abstract: A method and system of processing animal waste, whereby liquid is removed from the waste and recycled for use in other applications. Moreover, use of the method and system facilitates capture of the solid waste, which may then be used as fertilizer. In the present method and system, waste sludge is fed into a geotextile container, which functions as a filter. The liquid from the sludge permeates the geotextile container, while the geotextile container retains the solid waste. Multiple geotextile containers may be used to further filter and clean the liquid. The liquid exiting the geotextile container flows into a liquid reservoir, from which the liquid may be drawn for use in other applications. During this process, the solid waste is trapped in the geotextile container, where it will digest and compost and may be easily accessed for use as fertilizer or other nutrients.Type: GrantFiled: August 26, 2003Date of Patent: September 26, 2006Assignee: Nicolon CorporationInventor: Thomas C.

Patent number: 5735640Abstract: Geosynthetics and structures for earth reinforcement, stabilization and retention. Membranes used in such structures are formed by weaving a number of fill members, which are preferably fibrillated polypropylene members or strips, with a plurality of warp member sets, which are preferably formed of extruded polypropylene yarns. The woven membrane so formed sustains the moderate tensile loads imposed by earth reinforcement requirements in roadways, runways, and other ways. It is inexpensive because the materials are inexpensive and may be woven in a cost efficient way, and, if desired, in a way which allows the strength and tensile properties of the membrane to be varied for a custom application by varying the composition, number and disposition of the fill members and warp members.Type: GrantFiled: April 3, 1996Date of Patent: April 7, 1998Assignee: Nicolon CorporationInventors: Bradley Ross Meyer, William M.
