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.
