Abstract
A process for manufacturing a cellulosic paper product is provided. The process comprises forming an aqueous suspension of papermaking fibers; depositing the aqueous suspension onto a sheet-forming fabric to form a wet web; dewatering the wet web to form a partially dewatered web; topically applying a glycol compound selected from the group consisting of polyethylene glycol, triethylene glycol, glycerol and mixtures thereof to the partially dewatered web; and drying said wet web. The present invention also provides for cellulosic paper products exhibiting a reduced malodor upon wetting.

A process for manufacturing cellulosic paper product, the process comprising:
- forming an aqueous suspension of papermaking fibers;
- depositing said aqueous suspension of papermaking fibers onto a sheet-forming fabric to form a wet web;
- dewatering said wet web to form a partially dewatered web;
- topically applying a glycol compound selected from the group consisting of polyethylene glycol, triethylene glycol, glycerol and mixtures thereof to said partially dewatered web, said partially dewatered web having a fiber consistency of about 80% or less;
- and
- drying said partially dewatered web by passing heated air at a temperature of at least about 175° C. through said web.
A process for manufacturing a cellulosic paper product, the process comprising:
- forming an aqueous suspension of papermaking fibers;
- depositing said aqueous suspension of papermaking fibers onto a sheet-forming fabric to form a wet web;
- dewatering said wet web to produce a partially dewatered web having a fiber consistency of about 80% or less;
- topically applying a glycol compound selected from the group consisting of polyethylene glycol, triethylene glycol, glycerol and mixtures thereof to said partially dewatered web in an add-on amount ranging from about 0.5% to about 20% by weight of said papermaking fibers in said web;
- and
- drying said partially dewatered web.
A cellulosic paper product characterized as having a reduced malodor upon wetting, the cellulosic paper product being produced by a process comprising:
- forming an aqueous suspension of papermaking fibers;
- depositing said aqueous suspension of papermaking fibers onto a sheet-forming fabric to form a wet web;
- dewatering said wet web to form a partially dewatered web;
- topically applying a compound selected from the group consisting of polyethylene glycol, triethylene glycol, glycerol and mixtures thereof to said partially dewatered web, said partially dewatered web having a fiber consistency of about 80% or less;
- and
- drying said partially dewatered web by passing heated air at a temperature of at least about 175° C. through said web.
