20120065547 | DEVICES FOR PREVENTION OF PRESSURE ULCERS - A support surface, such as an underpad, for preventing pressure sores in a patient is a multi-layer textile assembly having a skin contact layer formed from a fabric of synthetic filament yarns woven to provide air permeability and moisture vapor permeability and having a thickness of less than 1 mm. An absorbent middle layer is formed from a breathable microfiber fabric woven to provide for moisture transition from an upper surface of the middle layer to a bottom surface of the middle layer. The skin contact layer and the middle layer are stitched together using a stitching pattern optimized to produce an open pattern with minimal puckering. A bottom layer is formed from a breathable, waterproof fabric woven from synthetic yarn to produce a moisture vapor transfer rate within the range of 5,000 to 20,000 grams per meter squared per 24 hours. The three layers are attached together around their outer edges. | 03-15-2012 |
20110092935 | FABRIC LINER FOR SKIN-CONTACTING ITEMS - A liner for use in skin-contacting garments and other objects that contact the skin has a moisture-wicking layer formed from a non-shearing, moisture-vapor permeable woven fabric of synthetic filament yarns which is treated with an anti-microbial substance. Additional layers may include a breathable, highly-absorbent microfiber fabric that draws moisture from the inner surface to the outer surface of the fabric where it may be retained, and a moisture transport layer. If multiple layers are used, all layers may be stitched together with a seam around the outer edges of the layers. The liner may be shaped to fit within a garment or other wearable-article, such as a bra cup, diapers and underpants. | 04-21-2011 |
20100121300 | Nursing Bra Pad - A nursing bra pad has a concave, cup-shape formed from a rounded section of multi-layer composite textile having a first, skin contact layer formed from a non-shearing, moisture vapor permeable woven fabric of synthetic filament yarns. A second layer and optional third layer are formed from moisture absorbing and retaining fabrics. The second layer is a breathable fabric that draws moisture from the inner to the outer surface of the fabric. The optional third microfiber layer provides moisture retention and may be positioned between the first layer and the second layer or between the second and fourth layers. The fourth layer, which may optionally be coated with polyurethane, is formed from a breathable, waterproof fabric woven from synthetic yarn to allow moisture vapor transfer away from the skin. The three or four layers are stitched together along their edges. The layers are stitched to generally conform to the shape of the breast. | 05-13-2010 |
