  • Publication number: 20220241115
    Abstract: A dermal dressing is provided that comprises a foam layer and an adhesive layer applied directly thereon. A textile fabric is arranged on a side of the foam layer facing away from the adhesive layer, and the textile fabric comprises a vertically-lapped nonwoven. A method for producing the dermal dressing of the first aspect is also provided. The method comprises: providing the foam layer; applying the adhesive layer to the foam layer; applying the textile fabric to a side of the foam layer facing away from the adhesive layer; and bonding the foam layer and the textile fabric. The dermal dressing has optimal properties for its use in preventing pressure ulcers.

  • Publication number: 20220203650
    Abstract: A wound cleaning product is described as used for sterile debridement of wounds. The wound cleaning product comprises a composite material having a foam layer and a fiber layer arranged on a surface of the foam layer. The fiber layer is at least partially thermally solidified, and the foam layer and the fiber layer are connected to one another by needling such that fibers of the fiber layer have penetrated into the foam layer and form capillary channels that extend from the fiber layer into the foam layer.

  • Patent number: 9259506
    Abstract: Fibers or one-dimensional, two-dimensional, or three-dimensional fibrous structures configured to be hydrogelling, produced from fibers made of a first fiber raw material, whereby the first fiber raw material contains water-soluble polyvinyl alcohol and/or polyvinyl alcohol copolymer, whereby the hydrogelling configuration of the fibers or fibrous structures is achieved by tempering the fiber raw material at a predetermined tempering temperature that is preferably higher than the glass transition temperature and/or lower than the melting or decomposition temperature of the first fiber raw material employed, as well as by tempering for a predetermined tempering duration, and whereby the fiber raw material is cross-linked by the tempering.

  • Publication number: 20030059587
    Abstract: A composite material, including at least one nonwoven fabric and a reinforcing material, thermally connected to it, situated in the form of regularly recurring patterns, which is derived from sheeting made of thermoplastic material. The new composite material may be used, for example, as an operating room coat, a textile outer material for one-time use, as a belt or in absorbent products, such as diapers or feminine hygiene products.
