Abstract

A method of creating a soft and lofty continuous fiber nonwoven web is provided. The method includes providing two molten polymer components having different melting temperatures to a spinneret defining a plurality of orifices, and flowing a fluid intermediate the spinneret and a moving porous member. The moving porous member is positioned below the spinneret. The method includes using the fluid to draw or push the two molten polymer components, in a direction that is toward the moving porous member, through at least some of the plurality of orifices to form a plurality of individual bi-component continuous fiber strands. The method includes depositing the continuous fiber strands on the moving porous member at a first location to create an intermediate continuous fiber nonwoven web, and removing and / or diverting some of the fluid proximate to the first location to maintain loft and softness in the deposited intermediate continuous fiber nonwoven web.

Description

technical field [0001] The present disclosure relates generally to methods of forming soft and lofty fibrous nonwoven webs, and more particularly to methods of forming soft and lofty continuous fibrous nonwoven webs. Background technique [0002] Nonwoven webs can include continuous fibers. Continuous fibers can be produced by continuous fiber nonwoven manufacturing operations to form continuous fiber nonwoven webs. In such operations, a fluid, such as air, may be used to draw or push continuous fiber strands of molten polymer from the spinneret downward toward a moving porous member, such as a moving porous belt. During drawing or pushing, the continuous fiber strand can be quenched and stretched. Fluid (ie, process air) flows to the moving porous member. In some cases, a vacuum may be applied beneath the moving porous member to help pull the continuous fiber strands and fluid toward the moving porous member. After the continuous fiber strands contact the moving porous ...
