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.
