Disclosed is a water-repellent nonwoven fabric made of a melt-blown fiber having a single filament denier of 0.005 to 2.0, wherein the fiber packing ratio is 5 to 70% and the water pressure rresistance index is 400 to 2,000 mmH.sub.2 O. The nonwoven fabric is used for an oil-water separating filter having a permeability to oil and non-permeability to water. A composite fabric comprising a combination of the nonwoven fabric and an air-permeable knitted or woven fabric laminated and integrated with at least one surface of the nonwoven fabric is useful as an air permeable and water repellent fabric.

Vegetable beverages are clarified or stabilized by using an adsorbent material consisting essentially of a specified N-substituted polyamide or polyamide mixture. The specified polyamide is such that 0.5% to 65% in number of the hydrogen atoms linked to the nitrogen atoms of the amide linkages in the main chain are substituted with substituents represented by the formula
