Abstract
Abstract When a composite material comprising a nylon non-woven fabric as a substrate and a paper material for cleaning a magnetic tape which has been stuck onto one surface or both surfaces of said nylon non-woven fabric is used as a ribbon used in a tape cleaning device for cleaning a magnetic tape and/or for cleaning a magnetic converter or a magnetic head for sending a magnetic tape, a decrease in a reproduction output due to static charge can be prevented, the generation of dust and the damage of the tape can be decreased, and a cleaning effect for the magnetic tape and/or the magnetic head can be improved.
