    摘要: A method of forming an air laid web of hydrogen bonded wood pulp fibers is disclosed. More specifically, a paper producing method is disclosed wherein microencapsulated hydrogen bond promoting material is thoroughly premixed with wood pulp fibers. The mixture is then air laid on a moving screen to form a three dimensional continuum. The microcapsules may then be ruptured by heat and/or pressure to release the hydrogen bond promoting material evenly throughout the continuum. The continuum may then be heated or pressed to further consolidate the web.

    摘要: A process and apparatus for forming an air-laid, nonwoven web from separate supplies of individualized fibers, such as textile and papermaking fibers. Supplies of fibers are fed to oppositely rotating lickerins that are rotated at speeds which are optimum for the fibers being individualized by the lickerins. The individualized fibers are doffed from the lickerins by centrifugal force and high velocity air streams directed against the fibers clinging to the lickerin clothing. The fibers from each supply are entrained in their respective air streams, which are impelled at high rates of speed toward each other, and the air streams come together in a mixing zone. The doffed fibers are given an initial trajectory as they leave their respective lickerins, and the inertia of the fibers in the air streams is sufficient to bring the fibers to the mixing zone and effect blending of at least a portion of the fibers from each supply in the mixing zone. In communication with the mixing zone is a suction actuated condensing means where the fibers are deposited to produce a nonwoven web of fibers, for example, an isotropic nonwoven web. The process and apparatus can be varied to form a variety of nonwoven webs, using as the fibers of these webs two different fibers of the same, or of different lengths. A variable that can be introduced to vary the web construction includes a baffle that can be interposed between the two separate air streams to control the location where the two air streams are intermixed.

    摘要: A process for forming an air-laid, nonwoven web from separate supplies of individualized fibers, such as textile and papermaking fibers. Supplies of fibers are fed to oppositely rotating lickerins that are rotated at speeds which are optimum for the fibers being individualized by the lickerins. The individualized fibers are doffed from the lickerins by centrifugal force and high velocity air streams directed against the fibers clinging to the lickerin clothing. The fibers from each supply are entrained in their respective air streams, which are impelled at high rates of speed toward each other, and the air streams are combined in a mixing zone. The doffed fibers are given an initial trajectory as they leave their respective lickerins, and the inertia of the fibers in the air streams is sufficient to bring the fibers to the mixing zone and effect blending of at least a portion of the fibers from each supply in the mixing zone. The combined air stream has a gas to fiber volume ratio of at least 12,000:1, so that the fibers are relatively widely spaced in their respective streams, as well as in the combined stream. In communication with the mixing zone is a suction actuated condensing means where the fibers are deposited to produce a nonwoven web of fibers, for example, an isotropic nonwoven web. With gas to fiber volume ratios of between about 12,000:1 to about 275,111:1 in the combined stream, highly uniform webs can be produced at a high production rate up to 550 feet per minute or greater. The process can form a variety of nonwoven webs, using as the fibers of these webs two different fibers of the same, or of different lengths. To vary the webs, a baffle can be interposed between the two separate air streams to control the location where the two air streams are intermixed. A novel web that can be produced by the process of the present invention is comprised of two different types of fibers, with the web characterized by having a predominance of one fiber type at one of its major faces, and a predominance of the other fiber type at the other of its major faces. The web includes a transition between the faces in which the predominance of the fibers decreases uniformly away from the face at which they predominate.
