Thenonwoven fabric alsocan have a low surface tension liquid strike through flow of less that 0.9 mlper second, a ratioof low surface tension liquid strike through flow to air permeability ofgreater than or equal toabout 0.016, or both. Personal hygiene articles can incorporate the nonwovenfabric orcomponent.
