Abstract
Official abstract text for this publication.
Multi-layer composite material, production and use thereof A multilayered composite material comprises as components: (A) a sheet material, (B) a material capable of absorbing water or aqueous fluids, (C) at least one bonding layer and (D) a polyurethane layer with capillaries passing through the entire thickness of the polyurethane layer, wherein the polyurethane layer (D) comes into direct contact with sheet material (A) or absorption-capable material (B) in one or more places.
First claim
Opening claim text (preview).
1 - 2 . (canceled) 22 . A process for producing a multilayered composite material comprising as components: (A) a sheet material, (B) a material capable of absorbing water or aqueous fluids, (C) at least one bonding layer and (D) a polyurethane layer with capillaries passing through the entire thickness of the polyurethane layer, wherein the polyurethane layer (D) comes into direct contact with sheet material (A) or absorption-capable material (B) in one or more places; the process comprising bonding a material (B), capable of absorbing water or aqueous fluids, to a sheet material (A), forming a polyurethane layer (D) with the aid of a mold, applying at least one organic adhesive uniformly or partially onto sheet material (A) bonded to absorption-capable material (B) and/or onto polyurethane layer (D) and then bonding polyurethane layer (D) pointwise, stripwise or areawise to said sheet material (A) combined with said absorption-capable material (B) 23 . The process according to claim 22 wherein said polyurethane layer (D) is formed with the aid of a silicone mold. 24 . The process according to claim 23 , wherein said silicone mold comprises a silicone mold structured with the aid of laser engraving. 25 . The process according to claim 22 , wherein said mold is structured by using a laser to cut wells into the mold which have an average depth in the range from 50 to 25 μm and a center-to-center spacing in the range from 50 to 250 μm. 26 . The process according to claim 22 , wherein an interlayer (E) is placed between said absorption-capable material (B) and said bonding layer (C), between said bonding layer (C) and polyurethane layer (D), or between two bonding layers (C).
