DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT AND BEST MODE

[0056] Referring now to the Figures, FIGS. 1, 2 and 3 are schematic views of a preferred embodiment of the fabric, fabricated into upper and lower undergarments 10 and 20, respectively, and suitable for use under military outer garments by military personnel “M”. As shown in other drawings and in the text below in further detail, the upper and lower undergarments 10 and 20 are fabricated of an open, mesh warp knit fabric 40 characterized by providing enhanced ventilation and other comfort and safety characteristics to the wearer, particularly when worn under heavy, densely knitted, woven or non-woven garments such as often worn by military, law enforcement, fire fighting, emergency and similar occupations.

[0057] FIG. 4 shows a single piece, upper and lower undergarment 30 fabricated of the same fabric 40.

[0058] Referring to FIG. 5, the exemplary fabric 40 is constructed of a plurality of longitudinally and transversely extending warp-knitted yarns constructed of synthetic, or synthetic and natural, fibers forming an open, planar framework, a segment of which is shown at reference numeral 42. As shown, the framework 42 defines diamond-shaped openings 44.

[0059] The combination of features of fabric 40, including the weight, number, size and shape of the openings 44 and thickness provide a high profile “standoff” between the skin of a wearer and an outer garment. This feature provides for enhanced air and moisture ventilation, allowing perspiration to evaporate more rapidly, and also provides at the same time a physical barrier between the skin and an outer garment, which may have a rough, abrasive inner surface texture.

[0060] The fabric 40 may be constructed of synthetic, or synthetic and natural, fiber yarns having the characteristics set out by way of example in Table A, below.

[0061] Fabrics within the scope of the invention may have differing characteristics from those as described in Table A, which is for purposes of example only. By reference to the ruler shown in FIG. 5, it will be observed that each square inch (6.5 cm) of the fabric 40 has approximately 12 openings formed by the warp knitting process. In this particular embodiment, the openings comprise approximately 40-55 percent of the surface area of the fabric, calculated by edge detection and area calculation.

[0062] FIGS. 6, 7, 8, and 9 are microphotographs of the technical face (FIGS. 6 and 7) and back (FIGS. 8 and 9) of the fabric 40 according to one embodiment of the invention, showing the warp knit intersection of adjacent yarns and the mesh openings 44 formed in the fabric 40. The diamond-shape opening 44 is particularly well shown in FIG. 7.

[0063] Referring again to FIGS. 2, 3 and 4, the garments 10, 20 and 30 can be constructed using conventional cut-and-sew techniques. Overedge seaming, for example, can be used to construct the garments 10, 20 and 30 from lengths of the fabric 40, and fabrics of other yarns and specifications can be incorporated into garments constructed of fabrics according to the present invention.

[0064] A mesh fabric and garments constructed from such fabrics according to the invention has been described with reference to specific embodiments and examples. Various details of the invention may be changed without departing from the scope of the invention. Furthermore, the foregoing description of the preferred embodiments of the invention and best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation, the invention being defined by the claims.
