Abstract
Methods for making cellulosic fiber webs using release aids containing one or more polyethers and one or more hydrophilic polymers. In at least one specific embodiment, a release aid having a first temperature can be applied to a drying surface having a second temperature. The second temperature can be greater than the first temperature. The release aid, in an aqueous solution that includes water and about 3 vol % of the release aid based on the total volume of the release aid and water, can have a cloud point greater than the first temperature and less than the second temperature at a pressure of 100 kPa. The method can also include adhering a cellulosic fiber web to the drying surface by contacting the cellulosic fiber web to the drying surface. The method can also include dislodging the cellulosic fiber web from the drying surface.
