Process for making wet-laid structures containing individualized stiffened fibers

Abstract From the Canadian patent

A process for making wet-laid structures containing individualized, stiffened fibers. The wet-laid structures are obtained by: providing a slurry containing individualized crosslinked fibers; depositing the slurry of fibers on a foraminous forming wire; directing at least one stream of fluid upon the fibers such that the fluid disperses flocculations of fibers and also inhibits the formation of additional flocculations of the fibers; and setting the fibers into a sheeted form while the fibers are in a substantially unflocculated condition. The step of setting the fibers into sheeted form may be performed by pressing the fibers against the forming wire with a screened roll such as a, …
