=== Summary of Invention ===
The cosmetic loofah sheet according to the present invention is mainly composed of a loofah fiber sheet obtained by flatly compressing the three-dimensional structure of loofah fibers, and gold leaf strips or gold powders are dispersed and bonded to the loofah fiber sheet. Is. In the present invention, preferably, an adhesive containing aloe vera mesophyll extract component, hyaluronic acid or collagen is applied to the loofah fiber sheet, and gold foil strips or gold powder is adhered to the sheet.

=== Effect of Invention ===
The cosmetic loofah sheet according to the present invention is not only bulky like a simple loofah fiber three-dimensional structure, but also flexible compared to a simple loofah fiber three-dimensional structure by appropriately crushing the fibers during compression processing. It becomes a fibrous tissue, and the touch becomes soft and gentle. When this cosmetic loofah sheet is soaked in hot water during use, the fibrous tissue swells moderately with moisture, further softens the skin, and does not feel any resistance to rubbing the facial skin. Of course, it may be used together with facial soap.

  When the facial skin is rubbed as described above with the cosmetic loofah sheet according to the present invention, not only the stains are well removed, but also the gold foil strips and gold powder applied and adhered to the loofah sheet come into contact with the skin, and Gold leaf strips and gold powder adhere to the skin. As a result, a beauty effect can be expected. In addition, when the adhesive contains aloe vera mesophyll extract components, hyaluronic acid or collagen, the cosmetic effect of these components on the skin can be expected.

  In the cosmetic loofah sheet according to the present invention, since the gold foil strips and the gold powder are present so as to be mixed into the fiber structure such as the labyrinth of the loofah sheet, when used as described above, Gold powder never detaches from the loofah sheet at the same time. Therefore, it lasts in terms of the effect of bringing gold leaf or gold powder into contact with human skin.

It is a perspective view of the loofah fiber tertiary structure used as a raw material. It is a perspective view of the compression processed loofah fiber sheet.

  Hereinafter, embodiments of a cosmetic loofah sheet according to the present invention will be described with reference to the drawings together with some examples of the manufacturing method.

  FIG. 1A shows a three-dimensional structure of a simple dry loofah fiber that retains the form of loofah used since ancient times. This is a cylindrical structure 1 that forms the entire outer shape, a core structure 2 that exists in the center of the hollow portion of the cylindrical structure 1, and a rib that connects the core structure 2 and the cylindrical structure 1 It consists of a texture 3. A well-known method for producing dry loofah will not be described.

  In FIG. 1B, the core tissue 2 and the rib-like tissue 3 are excised from the ordinary loofah fiber shown in FIG. In FIG. 1C, a cut is made in the tubular tissue 1 of FIG. 1B in which the core tissue 2 and the rib-like tissue 3 are excised, and the tube is opened to form a plate.

  Any of the three types of loofah fibers shown in FIGS. 1A, 1B, and 1C can be used as the raw material for the cosmetic loofah sheet of the present invention. As described in detail below, these loofah fibers are flatly compressed to obtain a very thin loofah fiber sheet 4 as shown in FIG. 2. In conclusion, the core structure 2 and the rib-like structure 3 are obtained. The sheet processed from the ordinary loofah fiber in FIG. 1 (A) including the inside becomes the thickest, the sheet processed from FIG. 1 (B) is a little thin, and the sheet in FIG. 1 (C) is processed. The sheet becomes quite thin.

  For compression processing of loofah fibers, a mechanical hammer (called a foil punching machine) that has been used for a long time in the manufacture of gold foil and oil blotting paper is used. The raw material raw material is sandwiched between covering sheet materials and placed on a machine hammer pedestal (the covering sheet material is applied so that the base material and the hammer do not directly touch the loofah fiber), and the loofah fibers are repeatedly hit with a mechanical hammer. As the number of hits increases, the three-dimensional structure of the loofah fiber becomes flat, the fiber structure is gradually broken, and the softening of the fiber is promoted.

  The covering sheet material used when hitting with a mechanical hammer plays an important role. Without the covering sheet material, the loofah fiber is directly struck to the metal member of the mechanical hammer. In this case, the slippage of the contact surface between the loofer fiber and the metal member is poor and the impact is too strong. However, the spreadability is poor and the loofah sheet with good properties is difficult to obtain.

  A preferred coated sheet material is the paper used in the mechanical hammering process in the production of gold foil or oil blotting paper. A typical punching paper is Japanese paper such as hand-made crusted paper. In particular, those that have been used in the manufacturing process of gold leaf or oil blotting paper are preferred. Moreover, Western paper, such as glassine paper, may be used which is used in the manufacturing process of gold leaf or oil blotting paper.

  In such a state that the three-dimensional structure of the loofah fibers shown in FIGS. 1 (A), (B), and (C) is sandwiched with such a covering sheet material, it is repeatedly struck by a mechanical hammer and compressed flatly to obtain the loofah fiber sheet shown in FIG. In this case, the spreadability of the loofah fibers is good, and a thin and soft loofah fiber sheet can be formed without causing excessive fiber breakage. In particular, the surface portion of the loofah fiber sheet in contact with the covering sheet material is finished very smoothly.

  As a next step, aloe vera jelly extracted from aloe vera mesophyll is applied to the loofah fiber sheet compressed as described above. Furthermore, after a gold leaf strip or gold powder is sprinkled and dispersed on the surface coated with aloe vera jelly, the aloe vera jelly is dried. In this drying step, the loofah fiber sheet coated with aloe jelly may be heated. The dried aloe vera jelly functions as an adhesive, and the gold foil strips and gold powder applied to the loofah fiber sheet are almost uniformly dispersed and bonded to the loofah fiber. After that, it is desirable to strike the loofah fiber sheet coated with gold foil strips or gold powder with a mechanical hammer an appropriate number of times by the same method as described above. In this way, the cosmetic loofah sheet according to the present invention is completed. The cosmetic loofah sheet may be cut into an appropriate size and commercialized.

  In the above example, aloe vera jelly is used as an adhesive, and effects such as bactericidal action by the extracted ingredients of aloe vera are imparted to the cosmetic loofah sheet. In addition, components that can be expected to have a cosmetic effect such as hyaluronic acid and collagen can be used as the adhesive. Furthermore, an adhesive containing an aloe vera extract component, hyaluronic acid and collagen as appropriate can be used. Thereby, the functionality of the cosmetic loofah sheet according to the present invention can be improved.

  The adhesive material as described above is not essential for adhering the gold foil strip or gold powder to the loofah fiber sheet. In the middle of the flat compression process by repeatedly striking the three-dimensional structure of the loofah fiber with a mechanical hammer, by proceeding the compression process while applying the gold leaf strip or gold powder to the loofah fiber, the gold leaf strip or gold powder is like a maze. It can be fixed between the loofah fibers by being intercalated between the loofah fibers and being pressed onto the fiber surface. In this method, when raw material is a loofah fiber having a tubular structure 1 as shown in FIGS. 1 (A) and 1 (B), if a gold foil strip or gold powder is applied to the inside of the tubular structure 1, Gold foil strips and gold powder can be dispersed and fixed deep inside the loofah fiber sheet. Also, as shown in FIG. 1 (C), when two raw materials of loofah fibers cut into a plate shape are combined with a gold foil sandwiched between them, and the combined state is repeatedly hit with a mechanical hammer and compressed flatly, The gold foil sandwiched between the two is crushed, and the gold foil strips are dispersed and bonded to the two loofah fiber sheets. Even with this method, the cosmetic loofah sheet according to the present invention can be produced.
