With reference to FIG. 4, a fabric article 310 in accordance with an alternative embodiment of the invention is illustrated. The fabric article 310 includes a fabric 312 having a first edge 314 and a second edge 318. A first polymer coating 322 and a second polymer coating 326 are applied to the fabric 312 along the first edge 314 and the second edge 318, respectively. The fabric 312 further includes a first side 330 and an opposite second side 334 both adjacent the first edge 314.

With respect to each of the embodiments described above, the locking features 46 and 50, 146 and 150, 246 and 250, 346 and 350 interconnect to form a waterproof seal. The waterproof seal is defined by a tortuous path. In other words, water must change directions more than once in order to penetrate the locking features from one side of the fabric to the other. The locking features do not require seam taping or sonic welding, methods currently used for waterproofing fabric seams. In addition, the locking features do not require the underlying fabric to be punctured, as is the case when stitching a zipper to fabric edges, thereby further enhancing the waterproof nature of a fabric article including the locking features.
Although the above embodiments of the invention have been described in the context of a fabric, other substrate material is also considered for incorporating the polymer coatings and locking features thereon. For example, cardboard, metals, or other polymers, may be suitable substrates. With each of the locking features described above, no sewing is required to interlock two edges of a fabric.
Applications of the fabric article include, but are not limited to camping and hiking equipment, upholstery and interior decor (e.g., window blinds), water sport activities (e.g., boating), personal clothing, and so forth. For example, a pop-up camping tent can include the fabric article to facilitate assembling the tent.
