Further dewatering of the cellulosic product occurs through a non-mechanical mechanism.
Claims21
A wet form cellulosic product forming process, the process comprising:
- providing a slurry;
- forming the slurry into a cellulosic product;
- dewatering the cellulosic product;
- and
- drying the cellulosic product;
- wherein the cellulosic product is further dewatered through a non-mechanical mechanism, the non-mechanical mechanism being provided by a soluble surfactant selected from the group consisting of a cationic surfactant, an anionic surfactant, a nonionic surfactant, a zwitterionic surfactant, and combinations thereof.
A wet formed cellulosic product forming process, the process comprising:
- providing a slurry,
- forming a cellulosic product from the slurry;
- pressing the cellulosic product to dewater the cellulosic product;
- and
- drying the cellulosic product;
- wherein the cellulosic product is further dewatered through a non-mechanical mechanism during the forming and the pressing of the cellulosic product.
A wet formed cellulosic product, the product comprising cetyl trimethylammonium bromide ((C16H33)N(CH3)3Br).
