Field of the Invention The present invention is used for a drainage bag of a sink in a kitchen or kitchen, a drainage bag attached to a triangular corner, a garbage dumping port, etc., and is a filter medium excellent in draining property and adsorbing oil. And its manufacturing method.

Description of the Related Art As the material, conventionally, paper, dry process long fiber or short fiber non-woven fabric made of synthetic fiber or natural fiber, net made of thermoplastic resin, knitted fiber fabric made of synthetic resin fiber or filament, perforated film and the like have been used.
Of these, paper-made filter media have an excellent ability to capture fine dust, such as the fact that their eyes are too fine and they are easily clogged, resulting in poor drainability in a short time. Since it is easily adsorbed, it has a poor oil adsorbability and a low water wetting strength.

のサイズや数が制限される。The non-woven filter media have good dust trapping properties and drainage properties, but the oil adsorbability varies depending on the material. If the amount of fibers per unit area is increased, the amount of oil adsorbed increases. Drainability is greatly reduced. Further, when hydrophilic fibers are used as the fibers, the adsorption capacity of oil decreases due to the adsorption of water. A filter material consisting of a net, knitted fabric, and perforated film has good drainability, and is inferior in the ability to capture fine dust,
Further, the size and number of holes in the film are limited in order to maintain the strength of the film.

るのが実状である。Among the oils used for cooking, the drainage oil of the tempura oil is collectively solidified and then discarded, but the oil left on the leftover food and other garbage, cooking utensils, dishes, etc. The actual situation is that it passes through the drainer bag together with the washing water used to wash cooking utensils and dishes, and is then discharged through the drain pipe.

が、いづれも水切り性の低下を来たす。In order to prevent oil from passing through, it is necessary for the filter medium to have a good draining property as well as an excellent oil adsorbing property. However, the conventional filter medium is focused on the dust capturing property, and the oil adsorbing property is high. No special consideration is given to sex. If you try to improve the oil adsorption with conventional filter media, use hydrophobic fibers, make the fiber diameter fine, increase the amount of fibers per unit area to increase the oil adsorption area, In the case of a non-woven fabric, a method may be considered in which the orientation of the fibers is made three-dimensional within the range of the thickness of the non-woven fabric to increase the number of oil-holding voids, but in any case, the drainage property deteriorates.

According to the filter medium of the present invention, the fine particles attached to the surface of the fiber increase the fiber surface area and improve the oil adsorption performance, but the fine particles to be attached do not have a decrease in water permeability because of their small particle size.
