の向上をも図るようにしたものである。The present invention improves the processing effect of the dusting tape and reduces dropouts by impregnating the tape base material with an appropriate amount of higher fatty acids in a dusting tape for removing foreign matter adhering to the surface of a magnetic tape. The friction coefficient of the magnetic tape surface is also lowered to improve running performance.

工程等においてもダスティングテープが用いられる。During the cutting process, foreign matter such as chips adheres to the surface of the magnetic tape and the cut edge, so immediately after cutting, a dusting tape that is wider than the magnetic tape is brought into contact with the magnetic tape surface to remove chips and other particles that may cause dropouts. We try to remove foreign substances. This dusting tape is also used in the assembly process of magnetic tape manufacturing. Further, dusting tapes are used in addition to manufacturing magnetic tapes, as well as in the dubbing process 9 installation process in print houses.

For example, a magnetic tape (2) from a so-called pancake (2), which is made of a 3-inch wide magnetic tape wound, is placed on a guide roll (3). 4), a dusting tape (5) is placed on the way to the cassette assembly process, and the second dusting tape (5) is brought into contact with the surface of the magnetic tape (2) while running at a low speed to remove the magnetic tape.

の接触面積。Conventional dusting tapes have been composed of tape-like bodies made of natural pulp, hemp or natural bulbs, synthetic fibers, and the like. The removal efficiency of foreign matter by dusting tape is affected by the density, thickness, elasticity, etc. of the dusting tape, and the contact area between the dusting tape and magnetic tape under processing conditions.

るものであった。However, with conventional dusting tapes, even if the same dusting tape is used and processed under the same conditions, the relative friction changes due to differences in the surface condition of the magnetic tape and the cut condition during cutting. When the size increases, for example, powder falls onto the dusting tape, resulting in an increase in dropouts.To counter this, conventional methods have had to reduce the contact area and contact pressure, resulting in a decrease in the removal efficiency of deposits. there were.

アウトの低減が図れる。According to the dusting tape of the present invention, since it is impregnated with higher fatty acids, when the dusting tape is brought into contact with the surface of a running magnetic tape, the relative friction between the dusting tape and the magnetic tape can be suppressed to a small level. . Therefore, since the contact area and contact pressure between the two can be set large, the removal efficiency of adhering matter such as cutting chips adhering to the surface of the magnetic tape and the cut edge during cutting is increased. As a result, dropouts can be reduced.

を作成する。A tape-shaped base material having a thickness of 50tI11 to 90 μm was prepared by dissolving higher fatty acids having 12 to 18 carbon atoms (e.g. lauric acid, myristic acid, valmitic acid, stearic acid) in a solvent such as a mixed solvent of methyl ethyl ketone, toluene and cyclohexanone. Impregnated with the solution and rapidly dried in the open at approximately 80°C to reduce the content of higher fatty acids after drying.
A dusting tape in which x satisfies 0<x≦20 mg/cJ is prepared.

プ切口部分の粉落ちが少ない。As is clear from Table 1, the magnetic tape whose surface was treated with the dusting tape of this example had reduced dropouts and a decrease in the coefficient of friction on the surface of the magnetic tape. Note that, compared to conventional dusting tapes, dusting tapes containing higher fatty acids cause less powder to fall off at the cut end of the magnetic tape.
