Abstract
The present invention discloses a nonwoven web and methods for manufacturing the nonwoven web. The present invention specifically discloses a nonwoven web that includes a co-forming process wherein a first gas stream includes meltblown fibers that are extruded from a first die head, a second gas stream that includes spunblown fibers that are extruded from a second die head and a third die head that includes pulp fibers that are extruded from a pulp nozzle. By sandwiching spunblown fibers between meltblown fibers during the co-forming processes, a nonwoven web having improved cross-machine direction tensile strength is formed.
