HIGH WICKING LIQUID ABSORBENT COMPOSITE

摘要

Disclosed herein is a high wicking liquid absorbent composite suitable for a wide number of uses including personal care products and the process for making the same. The composite is made from a relatively uniform mixture of from about 5 to about 20 percent fine wettable fiber, from about 3 to about 30 percent pulp fibers, from about 50 to about 90 percent superabsorbent and from 0 to about 10 percent binder, the percentages being on a dry weight basis. The mixture is compressed into a composite having a density of from about 0.1 to about 0.5 grams per cubic centimeter and a vertical wicking height of at least about 10 centimeters in one hour. The process involves forming a sheet comprising 50 to 90 percent fine wettable fiber and 10 to 50 percent pulp fiber on a dry weight basis. The sheet is then fiberized into a plurality of individual fibers within an air stream. A superabsorbent is then mixed with the fibers from the fiberized sheet in the air stream to form a uniform mixture and the uniform mixture is deposited onto a forming surface to form a composite. After forming the composite, it is compressed to a desired density.
