Abstract: An elastic fiber roll for use in embossers and super calenders has a cylindrical body supported on its cylindrical axis for rotation. The cylindrical body is formed from a plurality of compacted disk elements of a nonwoven-randomly laid, entangled mixture of fibers. The mixture of fibers includes from about 20% to about 75% polyester fibers and from about 80% to about 25% of cellulose fibers. The fiber roll is prepared by a process which includes the steps of: (a) forming an integrated nonwoven web from a mixture of cellulose fibers and polyester fibers; (b) cutting annular segments from the nonwoven web; (c) stacking a plurality of segments onto a rotatable shaft; (d) compacting the plurality of segments on the shaft to form a fiber roll; and (e) dressing the sides of the compacted disks to form a smooth cylindrical surface.

Abstract: The present invention relates to the treatment of particular filteraids to reduce the beverage soluble iron. In the method of the invention, a particulate filteraid, such as diatomite, is contacted with an aqueous solution of particular chelating agents. The process is applicable to treatment of loose filter media and is also applicable to the treatment of filter media in filter sheets. Lowering the pH during the time that the filter media is being contacted by the chelating agent produces an optimum affect.
