Abstract
Tissue products having improved bulk and softness are made by adding one or more softeners/debonders and a silicone glycol copolymer of the papermaking fibers at the wet end of the tissue machine, prior to the formation of the tissue web. Suitable softeners/debonders include organoreactive polysiloxanes, quaternary ammonium compounds, quaternized protein compounds, phospholipids, and silicone quaternaries.
Claims20
A soft tissue comprising papermaking fibers and from about 0.0001 to about 3 percent active matter, based on the weight of the fiber, of a silicone glycol and and from about 0.01 to about 6 percent active matter, based on the weight of fiber, of one or more softeners/debonders selected from the group consisting of quaternary ammonium compounds, quaternized protein compounds, phospholipids, silicone quaternaries and organoreactive polysiloxanes.
A method for making a soft tissue comprising:
- (a) adding one or more softener/debonders and a silicone glycol to an aqueous suspension of papermaking fibers, either separately or as a combined aqueous mixture, wherein the amount of softener/debonder is from about 0.01 to about 6 percent active matter, based on the weight of fiber, and wherein the amount of silicone glycol is from about 0.0001 to about 3 percent active matter, based on the weight of fiber;
- (b) depositing the aqueous suspension of papermaking fibers onto a forming fabric to form a tissue web;
- and (c) dewatering and drying the web.
