Abstract

PURPOSE:To enhance abrasion resistance, friction resistance, oil absorptivity, resistance to chemicals, cleanability, uniform coatability, heat resistance, and dimensional stability by forming a fibrous structure having aramide type resin films scattered on the surface and a gas permeability of 3-25cc/cm<3>/sec through the surface. CONSTITUTION:The surface of the fibrous structure has scattered aramide type resin films and a gas permeability of 3-25cc/cm<3>/sec through the surface, and when <3cc/cm<3>/sec, a function of removing a remaining toner becomes deficient, and when >25cc/cm<3>/sec, it is made difficult to diffuse a smoothing agent to be applied to said structure after treatment. The aramide type resin film is formed on the surface of the structure formed into a flat or cylindrical shape by impregnating or coating the structure with the dope of this resin and solidifying the dope by a wet or dry process.

(1) To remove residual toner that adheres to the cleaning roll (cleanability) (2) To be able to apply a small amount of smoothing agent evenly to the outer surface (uniform applicability) (3) During copying Ability to withstand operating temperatures for long periods of time (heat resistance and durability) (4) Abrasion resistance (5) Friction resistance (6) Oil absorption To satisfy these various required properties, hollow cleaning rolls have traditionally been used. An aluminum metal pipe covered with felt made of heat-resistant fluorine fiber or wholly aromatic polyamide fiber is used. The smoothing agent can be applied to the cleaning seal by injecting a small amount of the smoothing agent into one part of the felt and using diffusion, or by injecting the smoothing agent into the hollow part of a metal pipe and applying it to the felt through the hole in the pipe. Diffuse the smoothing agent into the surface. Uniform diffusion of the smoothing agent is carried out during rotation of the cleaning roll under heat and pressure. Heat-pressure rotation may be performed at a high temperature of 160 to 220°C. A cleaning rule coated with a film-like material instead of felt has also been used, but the removal of residual unnecessary toner and the uniform application of the smoothing agent are not good. Felt made from short fibers is also used. For example, felt made of fluorine fibers is used. It has excellent surface smoothness, abrasion resistance, friction resistance, heat resistance, etc., but also has strong water and oil repellency, so
The ability to remove unnecessary toner remaining on the cleaning roll is poor. Furthermore, for the same reason, the diffusion of the smoothing agent between the short fibers constituting the felt is also not good. SaraK's felt is made of fully aromatic polyamide fibers and is wear resistant.

Although it has many excellent features such as friction resistance, heat resistance, oil absorption, and ability to remove residual unnecessary toner, the uniform application of the smoothing agent is insufficient due to the large pore size in the felt. Furthermore, it is still far from sufficient in terms of eliminating fiber fuzz on the surface of the cleaning rule (felt surface) and maintaining the uniformity (smoothness) of the contact surface. In addition, as a cleaning tool that uses electrical charging to collect residual unnecessary toner, a film that is suitable for electrets such as perfluoroalkoxy or fluoroethylene propylene is subjected to electret processing such as corner irradiation and ion beam irradiation.

K coating a fiber structure with aramid resin
This is carried out using a known method such as a coating machine such as a knife coater, reverse roll coater, or gravure coater. In the case of coating by impregnation, a known method such as a dipping method or a spray method is used. The fiber structure impregnated with the 7-ramid dope in this way is immediately immersed in a mixed solution of water or a water-miscible solvent to solidify the aramid resin, and then, if necessary, a vacuum dehydrator is applied. , using a nip rule, etc., and then drying at ℃ using a chute dryer, non-touch dryer, tenter, etc.

In the case of the dry coagulation method, an explosion-proof dryer of the same type as above is used, and the temperature range is from a relatively low temperature range, for example, 50 to 60°C, to a high temperature range, such as 150°C, where the fiber material used does not deteriorate due to heat.
It is desirable to perform drying by gradually raising the temperature to about 200°C. If the impregnated or coated fiber structure is heat-treated at a high temperature from the beginning, the solvent will evaporate rapidly and a uniform coating will be formed. Therefore, the drying temperature is set within a temperature range of 50°C to 200°C. Appropriately 30SeC~30
It is preferable to allow the resin to pass through the resin for a time of about 300 m to evaporate the solvent and solidify the resin. The fibrous structure coated with aramid resin can be cut into appropriate dimensions as it is and then rolled around the roll pipe for use at ℃, or in order to obtain more rolling characteristics, it can be heated at ℃. Pressure treated,
It is desirable to improve the adhesion and adhesion between the constituent fibers of the fiber structure and the coating formed on the surface thereof, and to impart surface smoothness and flexibility.

In addition, for the purpose of streamlining the size of the bag, a felt-like structure or a woven or knitted fabric made of short fibers is first cut into appropriate dimensions, which are then rolled into a single layer or several layers in advance. A blended solution (dope) formed into a hollow pipe shape and partially or entirely prepared in the same manner as above;
That is, at least 1 weight of wholly aromatic polyamide resin
After impregnating or coating the solution (dope) dissolved in the above solvent, wet coagulation or dry coagulation is performed to form an aramid resin coating on the surface of the pipe-shaped fiber structure, reducing surface fluff as much as possible and smoothing the surface. Temperature temperature is also good.

In addition, after inserting this pipe-like fiber structure into an iron core etc., the surface is heated and pressurized to remove the aramid resin coating and constituent fibers formed on the surface of the pipe-like fiber structure. The smoothness 2 air permeability may be controlled at the same time as improving the adhesion and adhesion. The heating and pressurizing conditions at this time are a heating roll temperature of 160 to 350'C and a temperature of 1 to 35°C, depending on the processing speed, purpose of use, and necessary characteristics.
It is carried out at a linear pressure of K4/cm. The heating and pressing means is usually carried out by passing the pipe-like fiber structure through an iron core or the like, then pressing it against a heating roll and rotating it.

Not limited to this method, any method can be used as long as the original purpose can be achieved (for example, a method of passing a pipe-like fiber structure through an iron core etc. using a hot plate press, then sandwiching it and making a ring) This heat treatment process partially softens the aramid resin and increases the degree of adhesion with the fiber structure.At the same time, the fiber structure itself is also thermally set at high temperatures and has excellent properties. Heat-resistant stability, thermal durability 9 Surface smoothness and flexibility are imparted, and heat-resistant ventilation stability is improved, making it a fiber structure more suitable for use in copying machines than cow farming. In addition, if it is necessary to further increase the stability against heat, the temperature may be within a range that does not impair the mechanical properties of the fiber structure.
