摘要： A tissue sheet is made using a modified wet pressing process employing an integrally sealed air press. After initial formation and conventional vacuum dewatering, the wet web is conformed to the surface contour of a relatively coarse fabric to give the web a textured surface. By creating a pressure differential across the web of at least 30 inches of mercury and an air stream through the web of at least 500 SCFM/in2, the air press noncompressively dewaters the wet web to a consistency of about 30 to about 40 percent prior to a Yankee dryer. The web is dried to substantially preserve its three-dimensional, throughdried-like texture. The resulting web has an exceptionally high degree of bulk and absorbency not previously found in wet-pressed products.

摘要： A noncompressive dewatering device generates air streams that can be used to remove water from cellulosic webs in an energy efficient manner. Further, a wet-pressed machine can be modified to economically produce low-density tissue with an energy/capital efficiency greater than that of the throughdrying process. For instance, a cellulosic web can be non-compressively dewatered from a post forming consistency to a consistency from about 25 percent to the water retention consistency by passing air through the web with an Energy Efficiency at least 10 percent greater than that achievable using vacuum dewatering at the same speed. In particular embodiments, the web may be non-compressively dewatering to a consistency of at least 70 percent of the water retention consistency using about 13 or less horsepower per inch of sheet width, or to a consistency of at least 80 percent of the water retention consistency using about 30 or less horsepower per inch of sheet width, both at a speed of 2500 feet per minute or greater.

摘要： A dispersible wet wipe constructed of at two layers is disclosed. The first outer layer of the wipe substrate may have a density of between about 0.5 and 2.0 grams per cubic centimeter. The second outer layer may have a density of between about 0.05 and 0.15 grams per cubic centimeter. A triggerable binder composition binds said web substrate together. The wet wipe also includes a wetting composition including at least 0.3 percent of an insolubilizing agent.

摘要： A dispersible nonwoven web having at least three layers including a first outer layer, a middle layer, and a second outer layer. The first and the second outer layers including a plurality of short fibers, a triggerable binder, and at least one of the first or second outer layers including a plurality of long fibers. The middle layer including a plurality of short fibers, a triggerable binder, and optionally a plurality of long fibers. The dispersible nonwoven web having a weight percent of the long fibers in at least one of the first or the second outer layers that is greater than a weight percent of the long fibers in the middle layer.
