Abstract: Aspects herein are directed to garments that incorporate adaptive stand-off structures in the form of fluid-filled bladders that transition from a first shape to a second shape when exposed to moisture in the form of, for example, perspiration. When the fluid-filled bladders are in the first shape, the fluid-filled bladders are generally planar with a surface plane of a textile layer forming the garment so that the garment comes into contact or near contact with the wearer's body surface. When the fluid-filled bladders are in the second shape, they extend in a z-direction away from the surface plane of the textile layer forming the garment such that the textile layer is spaced apart from the wearer's body surface by the stand-off structures to reduce cling and facilitate the evaporation of perspiration.

Abstract: A hollow fiber membrane is made by covering a tubular supporting structure with a membrane dope and converting the membrane dope into a solid porous membrane wall. Optionally, a textile reinforcing structure in the form of a circular knit may be added around the supporting structure before it is covered in dope.

A porous supporting structure may be made by a non-woven textile process, a sintering process within an extrusion machine, or by extruding a polymer mixed with a second component. The second component may be a soluble solid or liquid, a super-critical gas, or a second polymer that does not react with the first polymer.

Abstract: In a method for structuring the surface of a substrate, a substrate is elastically expanded by the application of a tensile stress so that a surface area of the substrate in which a structure is to be created, is enlarged. Then, in the surface area, a structure is produced that is larger than the structure to be produced. For this purpose at least one solution is applied to the substrate, which solvent contains at least one solid substance dissolved in a solvent. The solvent is then removed from the surface of the substrate so that the solid substance remains behind. The expansion of the substrate is at least partly reversed by the reduction or removal of the tensile stress so that the size of the structure is reduced to the size of the structure to be produced. In the material of the substrate, a compression stress can also be created to reduce the size of the structure to the size of the structure to be produced.

Abstract: The present invention relates to a method for improving both adhesion between substrate and polymer layers and the durability of such composite structures; while maintaining the malleability and preferred characteristics of the original substrate. Quite unexpectedly, the application of a layer or film upon an uncured, encapsulated base substrate which has been encapsulated by the shear thinning methods of the present invention, results in superior adhesion of multiple layers when compared to conventional layering, coating or composite manufacturing methods.
