Abstract:
Under one aspect, an elastically extensible cohesive article having first and second oppositely-facing major exterior surfaces includes a foam layer, and a cohesive composition coating at least a portion of each of the first and second major surfaces. The article may include a second layer, e.g., an elastic layer, an elastic fabric, a woven fabric, a knitted fabric, a non-woven fabric, or a second foam layer, juxtaposed with and secured to at least a portion of the foam layer. The foam layer may have a plurality of open cells that define at least a portion of one of the major exterior surfaces of the article, The open cells may act as "suction cups" that enhance the cohesive properties of the article, for example if the article is wrapped around a body part. The article may also include a pad that can be applied to a wound.
Abstract:
A laminated elastic fabric includes a first carrier layer of non-elastic, open fabric, and a second layer which is elastic in a direction extending longitudinally of the fabric; a first outer fabric layer and a second outer fabric layer on opposing sides of the first carrier and second elastic layers, and a binder bonding the layers together. The carrier layer can be a warp knit/weft insertion fabric having knit yarns and fill yarns and oriented with the knit yarns thereof extending longitudinally of the fabric, the knit yarns being non-elastic, each of the knit yarns extending longitudinally of the fabric including a plurality of longitudinally-spaced knitted loops, and each of the fill yarns extending transversely of the fabric and through loops of the knit yarns.
Abstract:
A vapor permeable article includes a porous backing substrate and an open fabric applied to one surface of the backing substrate. The open fabric has a greater porosity than that of the backing substrate. The open fabric is coated with an adhesive in such a manner that the open fabric remains porous and vapor permeable. The coated article can have a greater tensile strength in the cross direction than in the machine direction, and the adhesive can penetrate into at least a portion of a thickness of the porous backing.
Abstract:
Pressure-sensitive adhesive articles with a backing that provides secure but reversible adhesion to the pressure-sensitive face of the article when the article is wound upon itself to form a roll. Such "non-stick" backings include a non-woven fabric carrying a binder, such as polychloroprene, butadiene-styrene copolymer or butadiene-styrene- acrylonitrile copolymer, that provides a soft and conformable layer that readily releases from an overlying adhesive layer of the article when the rolled article is unwound. Fig. IA is-an enlarged plan view of a portion of a pressure-sensitive adhesive tape with "non-stick" backing according to one or more embodiments.

Abstract:
In one aspect, a wound treatment system includes an inner layer comprising a foam material impregnated with a zinc oxide containing composition with or without calamine and/or ichthammol and in the presence or absence of antimicrobial agent (inorganic and/or organic). An optional outer layer comprises a short/long stretch compression bandage. In another aspect, a method of manufacturing the foam article impregnated with the zinc oxide containing composition is disclosed. In yet another aspect, a method of applying the wound treatment system to a patient's leg is disclosed. In still another aspect, a kit is provided including a foam layer impregnated with a zinc oxide containing composition; optionally, an elastic bandage component (e.g., long or short stretch elastic bandage); and, optionally, an outer stocking or sleeve, wherein the bandage system components are packaged together.
Abstract:
A vapor permeable article includes a porous backing substrate and an open fabric applied to one surface of the backing substrate. The open fabric has a greater porosity than that of the backing substrate. The open fabric may be a woven fabric comprising warp (MD) yarns and weft (CD) yarns, and the warp yarns may be of a lower denier than the weft yarns, so as to facilitate hand-tear of the assembled article. The open fabric is coated with an adhesive in such a manner that the open fabric remains porous and vapor permeable. The backing substrate can be a woven, knit or non-woven fabric, or a porous film, such as an apertured plastic film.
