Absorbent foam-textile composite sheet

Registered in accordance with French patent specification 1,165,801 on August 8, 1950, fabrics have already been proposed that are characterized by the fact that they consist of at least two textile fabrics, a hydrophilic and a hydrophobic, one of its surfaces being formed essentially entirely by the hydrophobic textile fabric. On the other hand has has recently come to be used as textile fabric compositions for use as clothing suggested on plastic foam.

The present invention is concerned with novel absorbent Foam-textile composites for therapeutic ,, physiotherapeutic or hygienic use, which is characterized by the fact that it consists of an artificial Sponge or plastic

substance with a cellular structure, where at least one side is lined with a hydrophobic but permeable textile material. The fabric can be in the form a woven, knitted or non-woven fabric Cloth are present. As for the achievement of the present Invention suitable hydrophobic textile fabrics can be plastic textiles based on SuperpοIyamid, Polyacrylonitrile, polyester, polyethylene, polypropylene, polyvinyl chloride, polyvinylidene chloride, chlorinated polyvinyl chloride, Mixtures or copolymers of these products, as well as artificial or natural textile fabrics, which one Treatment to make them hydrophobic.

The de-s Related threads can be made either from endless threads, from threads of short fibers, or from the union, or twisting made of endless threads and fine web; they can be made from a single fabric or from consist of various substances in an intimate mixture with one another.

As a sponge-like substance with a cell-like structure, one can use synthetic sponges or plastics based on use regenerated cellulose, polyamide, polyurethane, polyethylene, polyvinylchloride, etc., by possibly using - or also, not - reinforced by hydrophilic fibers. The above

The list of substances is of course only intended to give a hint and the present invention is in no way based on this. Restrict substances. -

The connection between the textile fabric and the fabric provided with individual cells can be achieved by welding or gluing or sewing the two already prepared elements or by covering the fabric with a foaming composition be effected. It is of course important that the type of connection chosen does not correspond to the permeability of the Ver binding of the two elements is harmful.

The new absorbing arpt ± tee = i are related as follows j the hydrophobic textile material comes into contact with the skin, brings and leaves sweat, urine and blood because of capillarity and other liquids through which subsequently the substance impregnate with cellular structure and thus protect the wearer from the consequences of cooling: and decomposition of these liquids: if they stay in direct contact with the skin.

The A9? * Ifeei manufactured according to the invention can be used to manufacture of diapers: or. Children's beds, sweat sheets, linen towels, napkins, sanitary napkins, surgical Tampons, bed wetting tampons, underwear, belts and to everything

serve analog hygienic uses. They can be impregnated with a germicidal product or sterilized using any treatment compatible with their nature. will.

The following examples illustrate the invention without restricting it

example 1

A 1/1 rib knitted fabric made from ' Polyvinylchloride fiber filaments of the metric number 40/2 were spot-welded onto a flexible foam sheet of 15 mm thick made of polyvinyl chloride with open cells, from the middle Diameter 0.5 M- attached. This article can be used as a '- Diaper or bed pad can be used. It is found. -That it does not cause the slightest gluteal erythema or any allergy. -

Example 2

A double jersey knit fabric made of polyvinyl chloride fiber threads of metric number 36/2 becomes point-wise on a sleek. Foam sheet of 8 mmPolyurethane sized with open cells of mean diameter 0.3M.

The obtained article can be effectively used as a linen undercloth to avoid openings.

In the accompanying drawing, two preferred embodiments of the invention are shown.

In Figure 1. is shown a web section of an absorbent "r --1 g * em according to the invention. In this figure, 1 denotes a hydrophobic fabric made of polyvinyl chloride fiber threads, which is fixed by spot welding on a flexible foam sheet 2 made of polyvinyl chloride.

In Figure 2, another track section is shown, in the one with 3 a jersey knit fabric made of polyvinyl chloride fiber threads is referred to, the point by point a flexible foam sheet 4 made of polyurethane is glued. -
