A treated fabric is constructed that is capable of withstanding extremely harsh weather and abrasion conditions in low temperature environments. The treated fabric comprises a woven or weft inserted warp knit synthetic fiber fabric which has a generally open construction and is pretreated with a chemical bonding agent to facilitate adhesion of a neoprene coating to the fabric. A neoprene, such as neoprene AD, having a highly crystalline structure and including effective amounts of low temperature plasticizers, antioxidants, and loadings, is applied to the fabric, and it is coated with a highly crystalline acrylic coating. The neoprene coating vulcanizes (cures) in use, such as when used as a geotextile fabric, the highly crystalline acrylic coating protecting the neoprene until it vulcanizes. The fabric may be attached to a nonwoven filter fabric, and formed into a bag which is filled with sand, grout, or the like during actual use of the geotextile fabric in the harsh environment.
A finished fabric suitable for harsh weather, low temperature, abrading environments, comprising:
A composite fabric comprising at least first and second fabrics,
A method of constructing a treated fabric comprising the steps of:
A method of utilizing a geotextile fabric comprising a synthetic fiber fabric having a generally open construction with a first highly crystalline unvulcanized vulcanizable neoprene coating, and a second ablative acrylic coating over the neoprene coating, comprising the step of exposing the geotextile fabric to a harsh, abrading, low temperature environment so that the unvulcanized vulcanizable neoprene coating vulcanizes during use in the environment, and the acrylic coating does not completely wear away until after vulcanization of the neoprene coating.
