ABSTRACT:
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.
