。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a defibrating roll for a synthetic resin film, and specifically, the separation of the sgelit film from the roll by utilizing the electrostatic action generated by friction between the film and the roll. It was developed to be effective.

間隔のスゲリットを施す手段が採られる。The production of striped yarn and spun yarn made from synthetic resin involves applying a needle blade roll that rotates at a circumferential speed several tens of times faster than the running speed of the continuously running synthetic resin film, and then using the roll. While rubbing the film surface,
A method is used to apply sugerite to the film at minute intervals using a needle with a sharp cutting edge.

阻害することさえ生じる。By the way, as a result of this streak treatment, the treated surface of the film is disturbed, such as by the formation of split ends or fluff, so that the film becomes entangled with the roll having needle blades. Furthermore, the rolls may accumulate so much that they completely fill the cutting edge, impeding the function of the roll.

なした解繊ロールを提案する。Therefore, in the present invention, in order to prevent the synthetic resin film from getting entangled with the needle blade roll during such split processing, at least the surface of the roll body is treated with a negative triboelectrostatic charging material such as FRP or other synthetic resin. We propose a defibrated roll made as follows.

い。That is, when a synthetic resin film is defibrated by the sugerite treatment, the surface of the film is rubbed by the metal needle blade of the defibration roll, and the film is charged with negative static electricity. On the other hand, according to the defibrating roll of the present invention, the surface of the roll body except for the needle blade is covered with a negative triboelectrostatic charging material, so that the film's charge transfers to this surface as well, resulting in a negative charging state. becomes. As a result, the synthetic resin film and the roll body repel each other due to their homopolar charging action, so that the synthetic resin film does not actively separate from the defibrating roll and become entangled.

It is coated with a negative triboelectrostatic charging material 2 such as P or other synthetic resin with a thickness of about 0.5 wn to 1+ma. Then, a metal needle blade 3 with a sharp cutting edge is inserted into the 1. A large number of charging materials are arranged and planted on the surface of the roll body 1 through the charging material 2. Incidentally, in the coating process of the charging material 2 on the roll body 1 and the process of implanting the needle blades 3, the needle blades 3 may be implanted after the coating process, but usually the metal roll body 1 is coated with the charged material 2 and the needle blades 3 are implanted. After planting the needle blade 3, the sheet-shaped charged material 2 is moved from the inclined direction of the planted needle blade 3 (direction making an acute angle with the circumferential tangent of the roll body 1).
The needle blades 3 are inserted into the roll body 1 in advance.
Applying or spraying the melt of the charging material 2 on the surface of the charging material 2;
When the roll body 1 is not fully cured, insert the needle blade 3 into the rubber plate coated with a release agent.
By rotating or rolling the charged material 2 stuck to the needle blade 3, it is possible to remove the charged material 2 and adjust the coating thickness of the charged material 2 on the surface of the roll body 1. Furthermore, if the needle blade 3 can be implanted and processed to the extent that the needle blade 3 can be held during operation, the entire roll body can be transferred to the previously charged material 2.

細な繊維状物となる。FIG. 2 is a configuration diagram showing an example of a fiber processing apparatus for synthetic resin film using the defibrating roll of the present invention. It is drawn into a stretching section consisting of clamping rolls 6 and 7. These two sets of clamping rolls 6 and 7 have a rotation speed that is about 10 times faster than that of the clamping roll 60 on the film drawing side. Therefore, when the film 5 passes through this stretching section, it is stretched in the running direction and fibrillated. The fibrillated film 5' is then drawn into a needle-edged roll 8, which is based on a defibrating roll of the present invention and whose entire surface is covered with the charging material 2. These needle blade rolls 8 are arranged so close to each other that the tips of the needle blades 3 are in contact with each other, and the fibrillated film 5' passing between them is pulled by the upper and lower needle blades 3. The film 5' is scratched and becomes fine fibrous materials that are torn as the film 5' travels.

がない。At this time, negative static electricity is generated on the fibrillated film 5' that is rubbed by the metal needle blade 3, and this is charged. At the same time, the charged material 2 on the surface of the roll main body that comes into contact with the charged film 5' is charged with negative static electricity as well as t1, so the fine fiber filaments 5'' are repulsed by the charged material 2, and the needle blade roll 8 Stay away from it and don't get entangled in it.

円滑且つ適正に行われる。Therefore, the film 5 is made into fibers and can be sent to the next processing step (for example, summing roll treatment, etc.) without disturbing the running condition. Moreover, since there is no entanglement with the needle blade roll 8, the function of the needle blade roll 8 is not deteriorated in the subsequent fibrillation process, and the process is carried out extremely smoothly and properly.
