ABSTRACT:
A nonwoven fabric is provided which is made from fibers comprising at least two thermoplastic polymers and a compatibilizer. One of the thermoplastic polymers is present as a dominant continuous phase and the other one or more polymers are present as a non-continuous phase or phases. The polymer of the non-continuous phase or phases has a polymer melt temperature less than 30.degree. C. below the polymer melt temperature of the continuous phase. The polymer of the dominant phase may be, for example, polypropylene and the non-continuous phase may be, for example, polyamide. The compatibilizer may be one of several such as zinc ionomers of ethylenemethacrylic acid or modified polypropylene with maleic anhydride. The fibers from which the fabric is made are generally between about 5 and 50 microns in diameter and the non-continuous phase may exist within the continuous phase as fibrils with a cross-sectional area at least 0.1% of the cross-sectional area of the fiber.
