Polypropylene fibers and devices that include a fatty acid monoglyceride added to the polypropylene as a melt additive are described. A hydrophilic enhancer material can be advantageously added to the polypropylene as a melt additive to enhance the hydrophilicity of the fibers and devices. An antimicrobial enhancer material can be added to the fibers to enhance the antimicrobial activity.

1. A wound dressing comprising:(a) an absorbent layer comprising hydrophilic polypropylene fibers having incorporated therein an amount of a C 8 to C 16 fatty acid monoglyceride effective to alone render the fibers hydrophilic;(b) a liquid-impermeable and moisture vapor-permeable backing sheet adhered to an outer surface of the absorbent layer; the backing sheet substantially coextensive with the absorbent layer; and(c) a liquid-permeable sheet that is substantially coextensive with an adhered to the surface of the absorbent layer opposite the surface to which the backing sheet is adhered. 2. The wound dressing of claim 1 wherein the absorbent layer further includes an absorbent additive. 3. The wound dressing of claim 2 wherein the absorbent additive is selected from the group consisting of wood pulp, cellulose, cotton, rayon, recycled cellulose, shredded cellulose sponge, and mixtures thereof. 4. The wound dressing of claim 2 wherein the monoglyceride is a glycerol monolaurate and the absorbent additive is wood pulp. 5. The wound dressing of claim 1 further comprising a hydrophilic enhancer material.
