Process for preparing soft tissue paper treated with a polysiloxane |
(57) Disclosed is a process for making soft tissue paper which includes the steps of wet-laying
cellulosic fibers to form a web, applying to the wet web, at a fiber consistency level
of from about 10% to about 80%, a polysiloxane material, and then drying and creping
the web to form the finished tissue paper. 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 paper.
