Abstract

PURPOSE:To handle easily and prevent foreign matters from getting mixed into extrusion liquid or the like by making a sheet by employing fiber pieces of far infrared ray radiating fiber as a paper making material or mixing the fiber pieces of far infrared ray radiating fiber and fiber pieces of another paper making material and constituting subject filter paper. CONSTITUTION:A filter paper 7 is formed by making fiber pieces 3 of far infrared ray radiation fiber as a paper making material and mixing the fiber pieces 3 with the fiber pieces 5 of another paper making material to constitute, for instance, a paper filter 1. In filtering the liquid, the radiation effect of far infrared rays can be actuated sufficiently. As the fiber pieces 3 are used for making the sheet, the fibers are entangled each other to eliminate the fall-off of fiber pieces 3. Also, as the fine particles of a far infrared ray radiation substance are retained firmly as fibers, the fine particles themselves are not fallen off. As the result, it is not required to pay special attention for transportation, preservation and the like of the filter paper, and handling of the same is easy.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention (tomo) relates to a filter paper that emits far infrared rays. [Prior Art 1] Recently, far infrared rays have been shown to mellow the taste of foods and drinks. Therefore, there is a method that applies far infrared rays to drip coffee, for example, as described in Japanese Utility Model Application Publication No. 189129/1983.In this publication, one company has produced a disposable paper filter for coffee. It is described that the paper filter has been coated or impregnated with ceramic particles that emit far infrared rays.It is not clear why such paper filters give the coffee a mellower taste, but the heat generated by far infrared rays during coffee extraction is not clear. It is presumed that the effect is because the coffee beans are heated evenly and given good activity. [Problem to be solved by the invention] However, the paver filter described in the above publication has a
Since ceramic particles are only attached to the surface of the bulp fibers, paver filters with the following problems
Dozens of sheets are stacked together and placed in one bag on the market. Overlapping Meba filters may be rubbed together during transportation, storage, or use. For this reason, there was a problem with conventional paper filters in that ceramic particles easily fell off.The result was that the effect of far-infrared rays could not be obtained sufficiently, and the particles that fell off or easily fell off became coffee. In order to prevent such falling off, there was a problem that it required extremely troublesome work such as storing each sheet one by one. Therefore, even when impregnated with ceramic fine particles, there is no difference in the end from adhering to the outer surface, and the problem of the present invention, which could not solve the above-mentioned problem of falling off. Filter paper E that emits far infrared rays
The purpose is to solve this problem, to make storage and other handling simple, and to prevent foreign substances from being mixed in with the extract. [Means for solving the problem] Filter paper that emits far infrared rays of the present invention 1. t. A filter paper that emits far infrared rays, which is produced by making a paper using pieces of far-infrared emitting fiber as a papermaking material, or by mixing pieces of far-infrared rays emitting fiber with pieces of another papermaking material [Function] Filter paper of the present invention (1. Fiber pieces of far-infrared emitting fibers are intertwined with each other, or fiber pieces of far-infrared emitting fibers and fiber pieces of other papermaking materials are intertwined with each other and overlap.
Therefore, the fiber pieces hold each other together,
Fiber pieces of far-infrared emitting fibers do not fall off L~ [Example] Next, an example in which the present invention is applied to a paver filter for extracting coffee will be described with reference to the drawings.

Example Paver Filter 11 Companies As shown in FIG. 1, the filter paper 7 is made of a mixture of far-infrared emitting fiber pieces 3 and pulp fiber pieces 5. Note that it is preferable to mix the amount so that it is distributed over the entire surface of the filter paper 7 on the far-infrared emitting fiber piece 31. As a far-infrared radiation emitting fiber piece 3 (for example, JP-A-63-
92720 can be used.
An example of the manufacturing procedure for filter paper 7 will be explained. First, the average particle size is 0. 6μ γ-alumina (γ-Af
f2 03) 30fiFJ! Polyamide 11 was melt-spun to form a sheath using mixed polymer 9, which was prepared by kneading 30 parts by weight of polyethylene wax and 30 parts by weight of polyethylene wax with polyamide powder, as shown in FIG. 2. A far-infrared emitting fiber i+lil3 having a core-sheath cross section can be obtained. This far-infrared emitting fiber 13 is cut into strips to obtain far-infrared emitting fiber pieces 3. The far-infrared emitting fiber piece 3 and the pulp 1a fiber piece 5 are mixed and formed to obtain a filter paper 7 as shown in FIG. 3(a). Length l. of far infrared ray emitting m fiber piece 3 and bulb fiber piece 5. t, should be selected depending on the roughness of the mesh when using paver filter 1. In addition, by making the paper 20 times, for example, If,
As shown in FIG. 3 (opening) 1: A layer (pulve layer) 17a consisting only of bulb fiber pieces 5 formed on the front and back sides and a layer (far infrared emitting layer) 17a containing far infrared ray emitting fiber pieces 3 in the middle.
Alternatively, as shown in FIG. 3(C), a two-layered filter paper 7b may be formed, in which a pulp layer 15b and a far-infrared radiation layer 17b are formed. In any of the filter papers 7, 7a, or 7b, the far-infrared emitting fiber pieces 31,t and the fiber pieces of the bulb 5 are intertwined with each other and do not fall off easily.

In addition, the filter paper 7a, 7b consisting of two or more layers 1; j.
．． The roughness can be varied for each layer 15a and 17a, 15b and 17b. Example 1f. Double-layered filter paper 7b
In 1 friend, the far infrared emitting layer 17b is a coarse layer, and the pulp layer 15b is a Beba filter 1 for coffee extraction.
It can be formed to the required coarseness. In this case, while maintaining the desired roughness, the far-infrared emitting layer 1
Hot water can easily pass through 7b, and the thermal energy of the hot water can sufficiently act on the far-infrared emitting material (gamma-alumina in this embodiment). As a result, a good far-infrared radiation effect can be obtained.

The filter paper 7, 7a or 7b thus obtained is formed into a paver filter 1 for coffee extraction by a conventional method. Here, in the case of using the filter paper 7b, by forming the paper filter 1 with the layer containing the far-infrared emitting fiber pieces 3 on the inside, far-infrared rays can be efficiently radiated to the coffee beans. Next 1:. Extraction of coffee using the vapor filter 1 will be explained.

Coffee extraction 1. As shown in Figure 4, the well-known drip method is used. Here, the paver filter 11 of this embodiment receives the heat of the hot water poured from the kettle 20 during coffee extraction and emits far infrared rays. coffee beans 221 top
Heat is also applied from the paper filter 1, that is, from the outside. For example, if the hot water seeping onto the surface of the paper filter 1 evaporates and takes away the heat of evaporation, the far infrared rays maintain the heat. Therefore, as shown in the figure, even the outer periphery, which is exposed to the outside air and has a poor heat retention effect, is kept at a good temperature by having grooves all over the surface. The unevenness of the coffee beans 22 becomes good, and a mellow coffee 24 is extracted. In addition, in the paver filter 1 in which the far-infrared radiation layer 17b is formed as an inner surface by using a two-layered filter paper 7b in which the far-infrared radiation layer 17b has a coarse mesh, the result is that the top coffee 24 is once retained in the far-infrared radiation layer 17b. , far infrared rays can be sufficiently applied to the coffee 24 after extraction. Including the antioxidant effect that is generally said to be the result of this,
Activated coffee 24 can be obtained. Also
Even when using a sandwich-like filter paper 7a, the far-infrared emitting layer 17a with a coarse mesh is sandwiched between the pulp layer 15a with a fine mesh (fine to the extent that the function as a vapor filter is satisfied). 24 can be retained in the far-infrared radiation layer 17a, and the same effect as described above can be obtained. Furthermore, three layers 15a, 17a,
It is also possible to adjust the residence time by adjusting the coarseness of t5a. Seven out of 10 people who tasted Coffee 24 extracted in this way agreed that the taste was mellower. Also
There is no visible foreign matter mixed into the coffee 24 liquid, and the effect of appealing to the eye as a luxury item is not impaired.X. Further, even when the paver filter 1 is rubbed together under normal conditions, no fiber pieces or the like are observed to fall off.

Incidentally, although the far-infrared ray emitting fiber piece 3 is effective regardless of the amount, coffee. As a filter; E. It has been confirmed that it is preferable to keep the blending amount below about 10% by weight in terms of extractability. Even if it exceeds 10%, there will be no problem, although the extraction performance will be slightly inferior. As described above, according to this embodiment, it is possible to obtain coffee in which the radiation effect of 1'L far infrared rays is sufficiently exerted.
Moreover, since the far-infrared emitting fiber pieces and the pulp fiber pieces are mixed and made, the fiber pieces are intertwined with each other and the #l fiber pieces do not fall off.In addition, the structure is such that the ceramic particles are wrapped in a sheath shape. Ceramic particles themselves do not fall off. As a result, far-infrared emitting substances are not mixed into coffee as foreign substances, and coffee that is good in both taste and sight and has high value as a luxury item can be obtained. In addition, when handling paper filters, even if you rub the inner surfaces of a bar filter or rub together dozens of stacked paper filters, the far-infrared rays and fibers entangled with the pulp fibers will easily be removed. Don't fall off LX. Therefore, there is no need to pay special attention to transportation, storage, etc., and easy handling is possible. Furthermore, the far-infrared emitting fiber pieces are difficult to fall off, so regardless of how you handle them, you can always expect a sufficient far-infrared radiation effect.

Although the paver filter for coffee has been described as an example, the invention can be applied to any filtration member or filtration device intended to impart a far-infrared radiation effect. Example 1'L As shown in Figure 5 1:. Oil strainer paper for tempura 3
It is also effective to use it as 0. The oil contained in Tempura 3212 is heated by the far infrared radiation effect of the oil strainer paper 30, increasing its fluidity, allowing for better oil removal.
In addition, the tempura 32 itself has a chewy and flavorful finish due to the heat retention effect and antioxidant effect of far infrared rays. Furthermore, ceramic fine particles and the like do not adhere to the surface of the tempura 32. Although ceramic fine particles are harmless to the human body, they are undesirable because they impair the texture when attached to food. Therefore, by applying the present invention to oiled paper, only extremely favorable effects can be expected, such as providing a far-infrared radiation effect without impairing the texture. As described above, the present invention exhibits an excellent effect that only favorable effects can be expected, especially when applied to food and drink products.

Note that the far-infrared ray-emitting fiber is not limited to the one in the embodiment, and any type of far-infrared ray-emitting fiber can be used. In addition, it is not necessary to wrap the ceramic fine particles in a sheath; for example, the mixed polymer 9 of the example can be spun alone.In this case, too, since the ceramic fine particles are not simply attached, far-infrared rays The radiating fiber pieces are intertwined with pulp fiber pieces or other far-infrared ray emitting fiber pieces, so they will not fall off during handling during transportation or storage. Furthermore, the far-infrared emitting fiber piece itself may be used as a papermaking material, in which case the entire filter paper will emit far-infrared rays. Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments and modifications.
For example, If. The mixing ratio of the far-infrared emitting fiber pieces and the bulb fiber pieces may be selected as appropriate, and it goes without saying that the present invention can be implemented in various other forms without departing from the gist of the present invention.

4. As explained above, according to the present invention, the far-infrared radiation effect can be sufficiently exerted during liquid filtration.Furthermore, the far-infrared radiation emitting fiber can be made into a paper by using fiber pieces. Therefore, the fiber pieces are intertwined with each other, and the far-infrared emitting fiber pieces do not fall off.Also, the fine particles of the far-infrared emitting substance are firmly held as fibers.
There is no dropout of the fine particles themselves. As a result, there is no need to pay special attention to transporting or storing the filter paper, and it can be handled easily. In addition, as the far-infrared emitting fiber pieces are difficult to fall off, a sufficient far-infrared radiation effect can always be expected regardless of how it is handled.
