う刃を磨損させることが多かつた。 Conventional cleaning tapes include abrasive materials such as alumina (Al 2 O 3 ), silicon carbide (SiC), chromium oxide (Cr 2 O 3 ), and red iron (α-Fe 2 O 3 ) on a support along with a binder. It is known to provide a cleaning layer by coating. Although these cleaning layers have sufficient ability to remove dirt, their abrasive ability is too strong, so they often wear out the heads and guide poles, and they also have problems when shredding into tapes or joining magnetic tapes. The blades used were often worn out.
かかる欠点を防止するために、研磨材に代えて

下する。 In order to prevent such drawbacks, a method was proposed in which the surface of the support was made matte by sandblasting instead of using an abrasive material (Japanese Utility Model Publication No. 49-42726).
issue). However, there are limits to the surface roughness that can be obtained with this method, and the breaking strength of the support is often reduced.

挙げることができる。 The cellulose powder used in the cleaning layer of the present invention is obtained by, for example, decomposing the amorphous region in the fine structure of wood cellulose by chemical treatment and separating the highly crystalline part, and the cellulose powder has a general length. It is a fine needle-shaped or rod-shaped powder with a diameter of 10 to 500μ and a thickness of 5 to 50μ. As a typical example of cellulose powder
One example is KC Flotsu (product name; manufactured by Kokusei Pulp Industry).

使用することができる。 In order to preserve the cellulose powder on a support, a binder (e.g. vinyl chloride-vinyl acetate resin, nitrocellulose, vinylidene chloride resin, acrylic resin, methacrylic resin) or a thermosetting resin (e.g. , polyurethane, phenolic resin, epoxy resin, urea resin). The mixture thus obtained is applied to all or part of one or both sides of the support. As the support and binder, those described in JP-A-53-77612 can be used.

い利点も有する。 The cleaning tape of the present invention can be used as an abrasive tape or a leader tape, and since cellulose powder is dispersed and fixed on the support surface, dirt adhering to the head and guide can be efficiently removed without damaging them. can do. Furthermore, the cleaning tape of the present invention also has the advantage of not reducing its own breaking strength, unlike cleaning tapes obtained by conventional sandblasting methods.
