Cellulose material with improved absorbency
View Patent ↗An absorbent cellulose material having an application of superabsorbent polymer adhered to the cellulose material. In particular, the cellulose material has an application of pre-superabsorbent polymer adhered to the material, wherein an aqueous solution of pre-superabsorbent polymer is applied to the cellulose material and converted to superabsorbent polymer upon subjected to heat for a sufficient time. The absorbent cellulose material has a fluid retention of greater then 2 g/g.
1. An absorbent cellulose material consisting essentially of a cellulose material having 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 wherein an aqueous solution of pre-superabsorbent polymer is applied to the cellulose material and converted to absorbent polymer upon being subjected to heat at a temperature of from about 110° C. to about 135° C. for a sufficient time wherein the superabsorbent polymer composition coated absorbent cellulose material has a fluid retention of greater than 2 g/g.
2. The absorbent cellulose material of claim 1 wherein the superabsorbent polymer composition has a neutralization of from about 60 mol% to about 70 mol%.
3. An absorbent cellulose material consisting essentially of a cellulose material having an application of an aqueous pre-superabsorbent polymer and superabsorbent polymer fines adhered to the material to form a superabsorbent polymer composition coated absorbent cellulose material, wherein an aqueous solution of pre-superabsorbent polymer is applied to the cellulose material and converted to superabsorbent polymer having a neutralization of from about 50 mol% to about 80 mol% upon being subjected to heat at a temperature of from about 110° C. to about 135° C. for a sufficient time wherein the superabsorbent polymer composition coated absorbent cellulose material has a fluid retention of greater then 2 g/g.
4. The absorbent cellulose material of claim 3 wherein the superabsorbent polymer composition has a neutralization of from about 60 mol% to about 70 mol%.
