Improved process for applying polysiloxane to tissue paper

Abstract From the Canadian patent

Disclosed is a process for making soft tissue paper which includes the steps of wet-laying cellulosic fibers to form a web; drying the web and elevating the web temperature creping the hot web, and , applying low levels of a polysiloxane material to the hot, creped web. Preferably, the hot web is dried to a moisture level below its equilibrium moisture content before application of the polysiloxane material. The process may further include the steps of applying an effective amount of a surfactant material to enhance softness and/or wettability control; and/or an effective amount of a binder material such as starch, for linting control and/or to contribute tensile strength to the tissue …
