METHODS OF CREATING SOFT AND LOFTY NONWOVEN WEBS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18449737 titled 'METHODS OF CREATING SOFT AND LOFTY NONWOVEN WEBS
Simplified Explanation
- The patent application describes a method for creating a soft and lofty continuous fiber nonwoven web. - The method involves using a spinneret with multiple orifices to provide molten polymer. - A fluid is then used to draw or push the molten polymer through some of the orifices towards a moving porous member positioned below the spinneret. - This forms individual continuous fiber strands, which are deposited on the moving porous member at a first location to create an intermediate continuous fiber nonwoven web. - To maintain loft and softness in the deposited web, some of the fluid is removed or diverted proximate to the first location.
Original Abstract Submitted
A method of creating a soft and lofty continuous fiber nonwoven web is provided. The method includes providing molten polymer 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 molten polymer, 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 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.
