Abstract: An embossed composite nonwoven web material includes a mixture of thermally unbonded continuous spunlaid filaments and short fibers including natural and/or synthetic fibers or staple fibers. The continuous filaments and short fibers being substantially mechanically bonded to each other by hydroentangling and the composite nonwoven web material being embossed without thermobonds to have a strength index equal to or more than 1 time the strength index of the unembossed composite nonwoven web material.

Abstract: A method for manufacturing a composite nonwoven web material includes extruding continuous filaments from a spinnerette, drawing the filaments by a slot attenuation unit to thin continuous filaments, forming a web of unbonded continuous filaments without thermobonds as the filaments are laid down, hydroentangling the web including continuous spunlaid filaments together with wet or foam formed short fibers including natural and/or synthetic fibers or staple fibers to integrate and mechanically bond and form a thermally unbonded composite nonwoven web material. A moist environment is created at the formation and lay down of the continuous filaments by the steps of laying down the filaments on an already wetted surface, keeping the width of the outlet of the slot attenuation unit open by more than 65 mm and adding liquid at the outlet of the slot attenuation unit.
