Abstract: A footwear construction that includes an improved footwear upper liner is provided. The liquid impermeable footwear upper liner is constructed of air permeable, waterproof and moisture vapor transmissive materials as well as air impermeable, waterproof and moisture vapor impermeable materials. A process for constructing a footwear component utilizing the improved footwear upper liner is also provided. The process comprises providing a sole; providing an upper that together with the sole define a volume for receiving and protecting a wearer's foot against external elements and securing the improved liquid impermeable footwear upper liner within the footwear so that the footwear upper liner is located underneath the upper. In an alternative embodiment, the improved footwear upper liner is attached to a sole to form a bootie for use in footwear construction.

Abstract: A shoe construction that includes a sole and an upper, wherein the sole and the upper together define a volume for receiving and protecting a wearer”s foot against external elements. There is a liquid impermeable bootie that includes an inner, upper liner that is attached to a sole liner. The inner, upper liner is preferably air permeable, moisture vapor transmissive and liquid impermeable and is located inside the upper. The sole liner is air impermeable, moisture vapor impermeable and liquid impermeable and is located above the sole. The sole liner is preferably, but not necessarily, inelastic. Materials that may be utilized for the inner, upper liner can include microporous membranes. Some of the types of materials that may be used for the sole liner can include inelastic, thermoplastic materials, fiber reinforced polymeric materials and nonthermoplastic materials. An alternative embodiment of the inner, upper liner is air impermeable, moisture vapor transmissive and liquid impermeable.

Abstract: A garment (20) for inhibiting relatively moving air from contacting a portion of a person wearing the garment. The garment (20) comprises a first panel (22) for inhibiting relative air movement contact against a portion of the body of the person. The first panel (22) includes a first fabric layer (62), a second fabric layer (64) and a first membrane (66) located between the first and second the first fabric layers. The first membrane (66) is water-resistant. The first panel (22) has an air permeability of not more than 3 CFM/ft.sup.2 and a moisture vapor transmission rate of at least 800 gm/m.sup.2 .multidot.day. The garment (20) also comprises a second panel (24) connectable with the first panel (22). The second panel (24) includes a third fabric layer (62a), a fourth fabric layer (64a) and a second membrane (66a) located between the third and fourth fabric layers. The second membrane (66a) is water-resistant. The second panel (24) has an air permeability of at least 6 CFM/f.sup.

Abstract: This invention provides a waterproof and breathable elastomeric polytetrafluoroethylene layered article for use in, for example, material for protective articles. The waterproof and breathable polytetrafluoroethylene layered article can for example, exhibit elastomeric properties of stretch to break of 275% in the machine direction, and 145% in the transverse direction and a total stretch recovery of at least 39% after being stretched to 75% extension for 100 cycles. This invention further provides a waterproof and breathable elastomeric polytetrafluoroethylene layered article bonded to a stretch fabric. The waterproof and breathable elastomeric polytetrafluoroethylene layered article bonded to a stretch fabric is thus durable and possesses a moisture vapor transmission rate exceeding 1000 gms/m.sup.2 day, and preferably above about 2000 gms/m.sup.2 day.
