ABSTRACT OF THE DISCLOSURE A nonwoven fabric is provided which comprises (a) a barrier layer which is substantially impermeable to water at room temperature and (b) a support layer which provides physical strength for the fabric. The barrier and support layers are bonded to one another to form the nonwoven fabric and each of the layers is composed of fibers which dissolve in an alkaline solution having a pH above about 12 and a temperature above about 70°C in a period of time of less than about 10 minutes. The fabrics can be disposed of by passage through the wash cycle of a commercial laundry wherein pH and temperature conditions of above 12 and above 70°C are achieved. The fabrics have physical and fluid barrier properties suitable for use in medical applications.
