Abstract
Soft creped tissue paper products comprising papermaking fibers and a crepe facilitating composition are disclosed. The crepe facilitating composition comprises a bonding inhibitor, a cationic starch and a carboxymethyl cellulose. Preferably, the bonding inhibitor is a quaternary ammonium compound. The use of a bonding inhibitor, a cationic starch and a carboxymethyl cellulose results in a creped tissue paper that is both strong and soft. A creped papermaking process comprising the addition of the crepe facilitating composition is also disclosed. The crepe facilitating composition offers the potential to improve production capacity.
