The method of claim 26 wherein the splitting step comprises impinging the splittable spunbond fibers with first high energy hydraulic jets, and wherein the entangling step comprises impinging the superposed first and second layers with second high energy hydraulic jets.28. The method of claim 27 wherein the first jets are supplied through first orifices, the hydraulic pressure at the first orifices ranging from about 2,500 kPa to about 21,000 kPa.29. The method of claim 27 wherein the second jets are supplied through second orifices, the hydraulic pressure at the second orifices ranging from about 1,300 kPa to about 14,000 kPa.30. The method of claim 27 wherein the first and second jets are supplied through first and second orifices respectively, the hydraulic pressure at the second orifices being lower than the hydraulic pressure at the first orifices.31. A composite fabric made by the method of claim 26.
