摘要:
A fibrous layer that includes a refined blend of crosslinked cellulosic fibers and noncrosslinked cellulosic fibers. In one embodiment, the layer includes about 85 percent by weight crosslinked fibers and about 15 percent by weight noncrosslinked fibers. An absorbent construct that includes the fibrous layer and a liquid storage layer. Personal care absorbent products that include the distribution layer.
摘要:
An insulating paperboard contains at least one layer of cellulose fibers. The one layer is at least partially composed of processed cellulosic fibers. The paperboard provides sufficient insulation to provide a hot water ΔT across the paperboard of at least 0.8° C. per 0.1 mm of caliper. A hot cup may be produced from the insulating paperboard.

摘要:
Methods for improving the internal bond strength of paperboard with greater than 25 percent crosslinked fiber in at least one ply are described. In the methods, additives are added to the slurry in various combinations and order while maintaining the ionic demand of the slurry at less than zero. Paperboard with high ZDT, Scott Bond and Taber Stiffness is obtained.
摘要:
An insulating paperboard contains at least one layer of cellulose fibers. The one layer is at least partially composed of cellulosic fibers and synthetic fibers. The paperboard provides sufficient insulation to provide a hot water AT across the paperboard of at least 0.6° C. per 0.1 mm of caliper change. A hot cup may be produced from the insulating paperboard.
摘要:
An unitary stratified composite composed of a first stratum and a second stratum integrally connected by a transition zone is disclosed. The first stratum serves as a liquid acquisition stratum that rapidly acquires and then transfers liquid to the second stratum. The second stratum serves to withdraw liquid from the first stratum and further severs as a temporary storage stratum. Methods for forming the unitary stratified composite are also disclosed.
摘要:
Methods for forming an absorbent fibrous composite containing absorbent material dispersed in bands through the composite and along the composite's length are disclosed. The methods generally include depositing a fibrous slurry on a foraminous support to form a web and depositing or injecting absorbent material into the web across its width to provide a web having absorbent material in bands along the composite's length. Drying the web provides a fluted absorbent composite. In one embodiment, the method is a wetlaid method and in another embodiment, the method is a foam-forming method. Preferably, the methods are twin-wire forming methods.
