Abstract:
1. A wound-covering hydrogel material which is prepared by spreading a hydrogel comprising 5-15% by weight of a water-soluble synthetic or semi-synthetic polymer selected from combinations of two or more of carboxyvinyl polymers, polyacrylic acid, partially neutralized polyacrylate and carmellose sodium, 15-30% by weight of glycerol, 40-75% by weight of water and 0.001-1% by weight of one or more crosslinking agents selected from the group consisting of dried aluminum hydroxide gel, aluminum glycinate, dihydroxyaluminum aminoacetate, synthetic hydrotalcite, and metal salt aluminometasilicates on a laminated two-layer film composed of a polyurethane film and hydrophobic fibers; wherein the wound-covering hydrogel material has a moisture permeability of 500-2,000 (g/m
