Abstract
The addition of a relatively small amount of a cationic silicone to the aqueous suspension of papermaking fibers in the wet end of the tissue making process provides improved tactile properties (softness) to the resulting tissue.
Claims10
A method of making a soft tissue sheet comprising the steps of:
- (a) forming an aqueous suspension of cellulosic papermaking fibers containing from about 0.01 to about 1 dry weight percent, based on the weight of the fibers, of a cationic silicone;
- (b) depositing the aqueous suspension onto a foraminous forming wire which retains the fibers to form a wet web;
- (c) dewatering or dewatering/drying the wet web;
- (d) adhering the web to a creping cylinder with a creping adhesive and (e) creping the web from the creping cylinder with a creping blade to form a soft tissue.
