Abstract
Disclosed is a process for making soft tissue paper which includes the steps of wet-laying cellulose fibers to form a web, applying to the wet web, at a fiber consistency level of from about 10% to about 80%, a noncationic surfactant, and then drying and creping the web to form the finished tissue paper. The process may further include the steps of applying an effective quantity of a binder material, such as starch, to the wet web for linting control, and to contribute tensile strength to the tissue paper.
