Abstract

The invention relates to cellulose fluff pulp products that are debondable into fluff with markedly lower energy input, to a process for making the products, and to absorbent products using the fluff. Most of the pulp products show no reduction in liquid absorbency rate from that of untreated fiber and significantly higher rates than pulps treated with the usual debonding agents. The products are made by adhering fine noncellulosic particles to the fiber surfaces using a retention aid. The fiber is preferably treated with the retention aid in an aqueous suspension for a sufficient time so that the retention aid is substantively bonded with little or none left free in the water.
The fine particulate additive is then added and becomes attached and uniformly distributed over the fiber surfaces with very little particle agglomeration occurring. The fiber is most usually not refined or only very lightly refined before sheeting. However, it may be significantly refined to produce a product having a very high surface area. Kaolin clay is a preferred particulate additive. The treated pulp may be mixed with other fibers before sheeting or after it is debonded into a fluff. The fluff is highly advantageous in the absorbent portions of personal care products such as diapers or sanitary napkins.
