Embodiment Construction

[0010] The multilayer technical composite according to the invention essentially comprises at least two layers. The first layer, which is in contact with the skin, is a fabric, and the second outer layer is formed by a semi-permeable membrane.

[0011] The first layer, which is in contact with the skin, may consist of cotton (more or less elasticated), silk or fabric to which chitosan, silver or other antibacterial substances or active ingredients have been added.

[0012] The second layer consists of a semi-permeable membrane material, preferably polyurethane 5-80 microns thick, which membrane has considerable elasticity to ensure comfort for the user. The membrane may be non-porous so that the active ingredient, if present, does not penetrate to the outside. In this way, the active ingredient is not wasted and since it does not reach the outer surface, it does not stain bed sheets, clothing or other dressing items.

[0013] The film is osmotically breathable and thus does ...

Abstract

The invention relates to a multi-ply technical composite, usable in particular for making medical aids, garments and medical articles, comprising at least two layers (2,3), the first of which (2), in contact with the skin, is a cotton fabric (elasticised to a greater or lesser extent) or silk, or fabrics to which chitosan, silver or another antibacterial substance or active constituent is added, and the second, outer layer (3) is constituted by a semipermeable membrane, such as polyurethane between 5 and 80 microns thick, with considerable elasticity in order to ensure the user's comfort. Receptors rechargeable with active constituents are inserted into fabric (2) and protected by the polyurethane membrane.

Description

[0001] The present invention relates to a multilayer technical complex that releases active ingredients, facilitates their absorption and can be used in particular as a medical tool or for making garments or structures that come into direct contact with healthy or diseased skin. Background of the invention [0002] The textile industry pays particular attention to market demands; the demand for materials for specific functions, such as textile fibers and fabrics with the function of contacting healthy and diseased skin, has increased especially in recent years. [0003] The materials currently used have proven not to be entirely satisfactory. Contents of the invention [0004] The object of the present invention is to provide a multilayer technical complex that guarantees a specific breathability in order to ensure optimal moisturization of the skin and ideal conditions for the action of the active ingredients. [0005] Another object of the present invention is to provide s...
