Abstract:
An apparatus for the application of atomized fluid to a web material having a first surface and a second surface opposed thereto is disclosed. The apparatus is provided with a fluid source disposed adjacent to the first surface of the web material and a receipt plenum disposed adjacent to the second surface of the web material. The receipt plenum provides a source of negative pressure to the second surface of the web material. A fluid disposed from the fluid source contacts the first surface of the web material and is caused to traverse therethrough by the source of negative pressure. A portion of the fluid contacting the first surface of the web material is contained by the receipt plenum.
Abstract:
Rotary spinning processes, more particularly processes for making hydroxyl polymer-containing fibers using a rotary spinning die, hydroxyl polymer-containing fibers made by the processes and webs made with the hydroxyl polymer-containing fibers are provided.
Abstract:
The present invention is directed to an apparatus for forming fibers. One embodiment of the apparatus includes a die assembly having a plurality of nozzles, one or more attenuation medium passages and a cover plate. The cover plate has a cover plate opening into which one or more of the nozzles may extend. The attenuation medium passages have a minimum cross-sectional area and the cover plate opening has a limiting cross-sectional area such that the minimum cross-sectional area of the attenuation medium passages is greater than the limiting cross-sectional area of the cover plate opening.

Abstract:
An improved method for creating fibers from a material dissolved in a solvent. In one embodiment, the method includes the steps of feeding a fiber making material dissolved in a solvent through a die including at least two rows of nozzles to form fiber strands. An attenuation medium is provided about the fiber strands. The attenuation medium is provided in a direction that is generally parallel to the fiber strands such that the attenuation medium elongates the fiber strands. The attenuation medium has a relative solvent-vapor content of at least about 50 percent.
