摘要: A hydrophilic ester polyurethane foam is flame laminated to a substrate using a thin sacrificial layer, preferably a sacrificial foam layer. The sacrificial layer in the resulting laminate structure has a thickness of 1.5 mm or less, and preferably is substantially burnt away. The resulting laminate exhibits good bond strength along its length and width without loss of liquid wicking and absorptive properties.
