DETAILED DESCRIPTION OF THE INVENTION

[0015] As shown in FIGS. 1-5, a bikini bottom 10 embodying the invention is formed from an outer layer 12 of a fabric which is strong and flexible, so that it can securely fit the wearer's body. The exact shape, size and design of the outer layer are not shown in detail, such features being matters of design choice. Various suitable designs are well known to the person of ordinary skill in the field of this invention. A popular choice for the outer layer is a poly-spandex (Lycra) fabric.

[0016] The crotch portion 14 of the bikini bottom is shown in FIG. 2.

[0017] FIGS. 3 and 4 show the crotch portion alone, with the outermost layer foremost. In FIG. 3, spotting is visible, as may happen with prior bikinis. FIG. 4 shows a spot-free bottom, the result of the present invention.

[0018] Like conventional bikinis, the bikini bottom of the present invention has an inner lining 16 which bears against the wearer's body. The inner lining is selected for qualities of comfort and its ability to absorb water.

[0019] According to this invention, an intermediate layer of waterproof material 20 is disposed between the Lycra fabric and the inner lining, as seen in FIG. 5. The particular waterproof material is chosen for its qualities of water imperviousness and comfort. The intermediate layer acts as a barrier and better prevents bodily fluids from reaching the outer layer of the bikini bottom.

[0020] A particularly preferred waterproof material is a two-ply antibacterial polyester terry cloth combined with a waterproof but air pervious (breathable) thermoplastic polyurethane (TPU) membrane.

[0021] The terry cloth preferably has a dry basis weight of about 110 g/m.sup.2. The membrane preferably is about 0.015 mm thick and white in color. The terry cloth may be made from an antibacterial yarn such as AntBAC, a product of Antex Group, Angls, Spain. AntBAC yarns incoporate silver ions to provide actibacterial qualities.

[0022] The membrane and cloth combined have a basis weight of about 148 g/m.sup.2. The material is eco-friendly, and biocompatible with human skin.

[0023] Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.

[0024] The outer, inner and intermediate layers are assembled by sewing or other techniques which are well known in the field of bikini design, and are therefore not described in detail.

[0025] Inasmuch as the invention is subject to modifications and variations, it is intended that the foregoing description and the drawings should be interpreted as merely illustrative of the invention defined by the following claims.
