The present invention relates to a high barrier polymer nonwoven, characterized in that the surface tension of the polymer material is decreased by the use of esters of carboxylic acids as a melt-additive. As a result of the decrease in surface energy the presented nonwoven fabrics show excellent properties with regard to low permeability towards low surface tension liquids, such as for example running bowel movement or alcohol, in hygiene applications. The properties are achieved without the use of fluorine-based chemicals or silicone coating, both of which represent the state of the art to impart the properties presented to polymer nonwoven fabrics.
