Abstract
The present invention relates to a nonwoven web comprised of metal or refractory fibers with nylon as a binder. The nonwoven web is prepared by forming a foam furnish by agitating the fibers in a foamed medium, and passing the foam furnish onto a screen and defoaming the furnish. It is preferred that the nylon binder is added to the foam furnish in the form of fibers. Once the furnish is defoamed to form a nonwoven web, the sheet is dried at a temperature sufficient to melt the nylon binder.
