    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.

    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.
