Process for manufacturing a cellulosic paper product exhibiting reduced malodor
A process for manufacturing a cellulosic paper product is provided. The process comprises forming an aqueous suspension of papermaking fibers; introducing sodium bicarbonate into the aqueous suspension; depositing the aqueous suspension onto a sheet-forming fabric to form a wet web; and dewatering and drying the wet web. The process of the present invention provides cellulosic paper products exhibiting a reduced malodor upon re-wetting.
1. A process for manufacturing a cellulosic paper product, the process comprising:
forming an aqueous suspension of papermaking fibers;
introducing sodium bicarbonate into said aqueous suspension;
depositing said aqueous suspension onto a sheet-forming fabric to form a wet web; and
through-drying said wet web by passing heated air through said wet web, wherein the temperature of said heated air is from about 190° to about 210° C.
2. A process as set forth in claim 1 wherein said aqueous suspension has a pH of from about 7.5 to about 8.5 after said sodium bicarbonate is introduced into said suspension.
3. A process as set forth in claim 1 wherein said aqueous suspension has a pH of about 8.0 after said sodium bicarbonate is introduced into said suspension.
4. A process as set forth in claim 1 wherein the temperature of said heated air is from about 200° to about 205° C.
5. A process as set forth in claim 1 wherein said papermaking fibers predominantly comprise secondary cellulosic fibers.
6. A process for making a cellulosic paper product, the process comprising:
forming an aqueous suspension of papermaking fibers;
introducing sodium bicarbonate into said aqueous suspension;
depositing said aqueous suspension onto a sheet-forming fabric to form a wet web, said sodium bicarbonate being introduced into said aqueous suspension prior to depositing said aqueous suspension onto said sheet-forming fabric; and
through-drying said wet web by passing heated air through said wet web, wherein the temperature of said heated air is from about 190° to about 210° C.
7. A process as set forth in claim 6 wherein said aqueous suspension has a pH of from about 7.5 to about 8.5 after said sodium bicarbonate is introduced into said suspension.
8. A process as set forth in claim 7 wherein said aqueous suspension has a pH of about 8.0 after said sodium bicarbonate is introduced into said suspension.
9. A process as set forth in claim 6 wherein the temperature of said heated air is from about 200° to about 205° C.
10. A process as set forth in claim 6 wherein said papermaking fibers predominantly comprise secondary cellulosic fibers.
