Cellulose Material With Improved Absorbency

January 27, 2009

An absorbent cellulose material was recently granted a patent. It consists essentially of a cellulose material with an application of superabsorbent polymer composition having a neutralization of from about 50 mol% to about 80 mol% adhered to the cellulose material to form a superabsorbent polymer composition coated absorbent cellulose material. An aqueous solution of pre-superabsorbent polymer is applied to the cellulose material and converted to the absorbent polymer upon being subjected to heat at a temperature of from about 110°C to about 135°C for a sufficient time. The superabsorbent polymer composition coated absorbent cellulose material has a fluid retention of greater than 2 g/g.
