Title: Method for making a throughdried tissue sheet

Abstract: A method for making a throughdried tissue sheet is disclosed. The method includes the steps of depositing an aqueous suspension of papermaking fibers onto an endless forming fabric to form a wet web. The wet web is then transferred to a throughdrying fabric such that the wet web has a fabric side in contact with the throughdrying fabric and an opposite air side facing away from the throughdrying fabric. The wet web is routed over a throughdryer to dry the web. The web is then transferred to a Yankee dryer for further drying and is creped from the Yankee dryer to obtain a creped web having a basis weight of about 15.2 pounds per 2880 square feet. The creped web in then calendered in a calendering unit that includes a smooth calender roll and a resilient calender roll. The resilient calender roll has an exterior covering formed of ethylene propylene diene polymer and the creped web is oriented such that the fabric side is disposed toward the resilient calender roll. The finished tissue exhibits improved softness while retaining adequate strength.
