A method of durably rendering a polymeric fabric, e.g., a polyolefin fabric, wettable and resistant to protein adsorption. The method involves applying to the surface of the polymeric fabric a composition which includes water and a surfactant adapted to durably render the polymeric fabric resistant to protein adsorption, and drying the polymeric fabric. The surfactant has a solubility in water at 20 DEG C no greater than about 5 percent by weight, based on the weight of the water, and is present on the polymeric fabric in an amount of the surfactant sufficient to reduce the adsorption of the protein by the fabric. The coated fabric not only exhibits durable reduced adsorption of protein but also has durable wettability by aqueous liquids. The coated fabric is especially suited for incorporation in such disposable absorbent articles as diapers, feminine care products, such as sanitary napkins and tampons, incontinent care products, training pants and wipes. The surfactant is preferably a polysiloxane-polyether of formula <IMAGE> where R1 and R6 are each hydrogen, alkyl or aryl; R2 to R5 are each alkyl or aryl, a is 8 - 25; b is 8 - 25; c is 1 - 10; and d is 40 - 100.ane-p |
