Absorbent products and methods of preparation thereof
View Patent ↗An improved absorbency material for absorbency applications comprised of a cellulosic fibrous material wherein said cellulosic fibrous material such as pulp is a cold alkali solution treated material at a treatment temperature of less than about 50° C.; a process for improving absorbency and other characteristics of said pulp.
1. An absorbent personal hygiene device comprising: a layer that allows liquid to pass, a water barrier sheet, an absorbent core interposed between said layer and said sheet, the absorbent core containing fluffed wood fiber pulp, wherein said fluffed wood fiber pulp comprises wood fiber pulp that has been cold caustic extracted at a temperature between 15° C. and 60° C. and fluffed by mechanical action and is without chemical crosslinking.
2. The personal hygiene device of claim 1 , wherein said absorbent core contains at least about 25% of fluffed cold caustic extracted wood fiber pulp.
3. The personal hygiene device of claim 2 , wherein said wood fiber pulp has been cold caustic extracted at a temperature below 50° C.
4. The personal hygiene device of claim 2 , wherein said wood fiber pulp has been cold caustic extracted at a temperature below 40° C.
5. The personal hygiene device of claim 2 , wherein said wood fiber pulp has been cold caustic extracted at a temperature below 35° C.
