A nonwoven liner for a diskette cartridge is made of hydroentangled fibers and impregnated with a small amount of binder which is uniformly distributed throughout the fabric. The binder comprises no more than 5% by weight and preferably between 1.5-3.0% by weight of the fabric. The low concentration of binder ensures that the liner surface does not become totally coated with plastic film that reduces cleaning ability, while also providing improvements in tensile strength and debris reduction. The binder solution preferably has a high surface tension (low surfactant level), so that the binder becomes concentrated at the junction points of the fibers throughout the fabric. The low level of surfactant ensures a low risk of chemical attack of the disk media surface. The hydroentangled fabric cleans the disk media more efficiently, has less fiber debris, contains less environmental contaminants, is substantially loftier, and is cut with cleaner edges than standard thermally bonded diskette liners.
