ABSTRACT:
An hydroentangled integrated composite nonwoven material, includes a mixture of randomized continuous filaments, and synthetic staple fibers, where there are no thermal bonding points between the continuous filaments. The nonwoven material exhibits a cumulative pore volume, measured by PVD in n-hexadecane, in the pore radius range 5-150 μm, where at least 70% of the cumulative pore volume is in the pores with a pore radius above 45 μm. The nonwoven material also exhibits a cumulative pore volume, which when the synthetic staple fibers are chosen from the group of polyethylene, polypropylene, polyester, polyamide, and polylactide staple fibers is at least 9 mm3/mg, and when the synthetic staple fibers are lyocell staple fibers is at least 6 mm3/mg.
