Abstract: A liner for a floppy disk comprising a partially thermocompression-bonded nonwoven fabric composed of a cellulosic fiber and a polyester, core-sheath type conjugated fiber wherein the melting point of the sheath component is lower than that of the core component, in which the mixture ratio of the conjugated fiber decreases gradually from the inner part toward the outer part of the liner, and parts heat-bonded in a dot or in a line through the conjugated fiber are present in a large number in the non thermocompression-bonded parts.

Abstract: A liner for a floppy disk which comprises a nonwoven fabric and a high molecular resin attached thereto, said nonwoven fabric containing thermoplastic fibers and being of a structure wherein a thermocompression-bonded part and a non compression-bonded part are present and the form of the fabric is maintained through the thermocompression-bonded part, and a process for producing a liner for a floppy disk which comprises partially thermocompression-bonding a sheet-formed fiber aggregate containing thermoplastic fibers and then attaching a high molecular resin thereto.
