ものである。Detailed Description of the Invention (Industrial Application Field) The present invention provides a heat fixing roll of a PPC (dry copying machine) and an LBP (laser beam printer) to make the toner and paper peelable on the surface of the roll. The present invention relates to a cleaning sheet that is coated with silicone oil that enhances the cleaning properties and is used to clean the surface of the roll without damaging it.

A combination of oil-coated felt soaked in a silicone oil storage tank, (c) a roll covered with felt, fabric, paper, etc. impregnated with silicone oil, and (ii) a cylindrical body sealed with silicone oil with through-holes provided. There are rolls with a cylindrical body covered with felt, fabric, paper, etc.

あった。As a method for solving these problems, there is a method of supplying silicone oil that enhances the releasability of toner and paper to the surface of the heat fixing roll, and at the same time wiping off stains such as toner and the like on the roll surface. However, in the case of (a) above, not only is it not possible to remove toner etc. sufficiently, but the next toner adheres on top of the remaining toner, making it harder to peel off the paper, causing it to wrap around the roll, and staining the copied image. There will also be more. Also, the above (
In the case of (b), the cleaning effect is not sufficient, and on the contrary, the disadvantage is that the equipment becomes larger and the cost increases due to the division of oil application and cleaning action. On the other hand, in the case of (c) and (2) above, in which oil application and cleaning are performed at the same time, the total area of the cleaning portion of felt, fabric, paper, etc. is small, resulting in a shortened maintenance cycle and increased running costs. Furthermore, in order to increase the total cleaning area, the diameter of the roll must be increased, which has the disadvantage of increasing the size of the apparatus.

という欠点があった。In order to eliminate the above drawbacks, as shown in Japanese Patent Application Laid-Open No. 58-19971, aromatic polyamide fibers and polyethylene terephthalate fibers are made of a winding type pre-impregnated with silicone oil to provide heat resistance. A cleaning roller made of non-woven fabric using As a result, the coefficient of friction between the heating fixing roll and the cleaning roll becomes small, and the physical effect of cleaning is reduced. In addition, there are problems such as a decrease in porosity due to high density due to heating and pressing of the parallel web, and there is a limit to the amount of silicone oil that can be retained, resulting in shortcomings such as a short cleaning effect and a short lifespan.

点を解消したものである。(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides heat-resistant fibers such as aromatic polyamide fibers, 4-6 nylon or carbon fibers, and thermoplastic fibers having a lower melting point than the heat-resistant fibers. A nonwoven fabric made of a parallel web layer mixed with binder fibers and a cross web layer made of heat-resistant fibers such as aromatic polyamide fibers, 4-6 nylon, or carbon fibers interlaced and bonded by hydroentangling method. This problem has been solved by providing a cleaning sheet with high strength, heat resistance, and excellent silicone oil retention and cleaning effects.

ｍ以上）を得る事を目的としている。Normally, hydroentangled nonwoven fabrics are obtained by entangling fiber webs with high-pressure fine columnar fluids injected from multiple orifices.The fibers are entangled in a complex manner by the action of high-speed fine water jets, resulting in high strength and high airflow. A nonwoven fabric with porosity can be obtained, and it is possible to produce a thinner nonwoven fabric in a shorter period of time than with a mechanical 21-dollar punch processing device.゛The present invention has been made by focusing on the characteristics of the above-mentioned hydroentangled nonwoven fabric, and the cross web layer obtained by the hydroentangled method has many micropores, which are the characteristics of the hydroentangled method.
In addition, since a binder fiber resin binder, etc., which acts as a bonding agent between fibers, is not used, there are many voids, and the amount of silicone oil retained is excellent. Furthermore, due to the cross-web structure, the contact resistance with the fixing roll is increased, and cleaning effects such as toner removal are also increased. On the other hand, the lower layer serving as the supporting base material is a thermoplastic binder such as polyester fiber, polyamide fiber, polypropylene, polyolefin thermobond composite fiber, polyester thermobond conjugate fiber, polyamide thermobond conjugate fiber, etc., which has a lower melting point than the heat-resistant fibers to be mixed. It consists of a parallel web layer composed of heat-resistant fibers containing fibers, and has the necessary strength (@ i direction strength 10% modulus 6kg/5c

なり、寿命が短くなるなどの問題が発生する。The weight ratio of the cross-wrap layer to the parallel web layer is 30.
It is preferable that the ratio is in the range of 70 to 60: 40. If the parallel web layer is less than 30%, it will not be possible to obtain the necessary strength when winding to the core, and if the cross web layer is less than 20%, silicone Problems such as a decrease in the amount of oil retained and a shortened lifespan occur.

It is unsuitable to use wire mesh with wire mesh, and intertwining on a high-density wire mesh is suitable.
