Abstract
Described is an improved two-step process for treating lightweight nonwovens to impart single-sided anti-static and alcohol repellency properties while maintaining good barrier characteristics as measured by hydrostatic head values. The resulting nonwovens find particular uses as infection control product medical fabrics for sterilization wrap and surgical gowns, for example.
