Abstract

A method of creating a soft and lofty continuous fiber nonwoven web is provided. The method includes providing a first molten polymer and a second, different molten polymer to a spinneret defining a plurality of orifices and flowing a fluid intermediate the spinneret and a moving porous member. The method includes using the fluid to draw the first and second molten polymer components, in a direction toward the moving porous member, through at least some of the plurality of orifices to form a plurality of individual continuous fiber strands. The method includes depositing the continuous fiber strands onto the moving porous member at a first location to produce an intermediate continuous fiber nonwoven web, and intermittently varying a vacuum force applied to the moving porous member and to the intermediate web downstream of the first location and without the addition of more continuous fibers and without any heat applied.
