Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-absorbency cosmetic absorbent paper and a method for producing the same.

[0002]

2. Description of the Related Art The face of a human, particularly between the nose, cheeks, forehead, and eyebrows, tends to become greasy due to the secretion of sebum, and the makeup tends to be lost in that part. In general, if makeup is applied while sebum is floating, cosmetics do not fit into the skin. Therefore, makeup is applied after removing fat on the face with a cosmetic fat removing paper. This is the same in the case of makeup correction.
Foiled paper has been used for a long time as the conventional degreasing paper for makeup, and Meisho paper is famous. This paper is from Nishinomiya City
It is a paper made by mixing mitsumata, mulberry, and goosepicks with special mud, for example, gold-foiled with a white thing called Higashikubo soil, and silver-foiled with a dark brown thing called snake bean soil.

When the foil punching paper is used about 15 times for foil punching, it loses the function of extending the foil punching and is used as a female degreasing decorative paper. After salting paper,
The density is as high as 0.94 kg / cm ^3, and when this is used as a grease-removing decorative paper, the grease on the face is removed,
Since he started to take a bath, his name has been used as a bathhouse paper for a long time.

[0004]

The cosmetic fat removing paper used in the prior art has a limit in mass production due to hand-making, and recently, a special inorganic filler such as clay, After mixing talc, kaolin, calcium carbonate, titanium oxide, etc., after adding a special fixing agent,
In order to increase transparency after making paper and using it as decorative paper,
It is used in mass production after being processed by a calender etc. so that it has a high density like Nao Shio.

[0005] However, with the current cosmetic fat removing paper, the transparency after use is high and it seems that oil and fat are removed.
There is a problem that the oil and fat on the face cannot be completely removed even if it is repeated many times.

SUMMARY OF THE INVENTION An object of the present invention is to provide a highly oil-absorbing cosmetic fat-absorbing paper, which has a high absorbency of true sebum in one use and a property of high transparency after use, and a method for producing the same.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a raw material mainly composed of vegetable fibers, a papermaking net, a dandy roll or an embossing roll at the time of paper making. The gist of the present invention is a highly oil-absorbing cosmetic fat-absorbing paper characterized in that an uneven layer is provided on one surface or both surfaces of the uneven member.

[0008] The plant fiber in the present invention refers to at least one selected from bast fiber or wood pulp composed of Manila hemp, flax, jute, sisal, kenaf, ganpi, kozo, banana fiber, mitsumata, Means that the plant fiber is contained at 50% by weight or more.

In the case of a degreased paper having no concavo-convex layer, oil is absorbed only in the thickness direction of the paper, so the oil absorption amount is limited by the thickness of the paper. Also, feel and strength when used (hard to break when used)
- from ease of use, the basis weight of the paper is in the range of 15~25g / m ^2, there is a limit to the amount of oil absorption during use, enough to take not particularly with the use of only one case a lot of sebum such as facial Therefore, it may occur when two or three sheets are used. If there is an uneven layer on one or both sides of the paper, sebum will be absorbed in the recesses,
Since the oil is absorbed in the surface layer portion of the uneven layer surface and in the thickness direction of the paper and a high oil absorption is obtained, a sufficient effect can be obtained even when only one sheet is used, particularly when the face or the like has a large amount of sebum.

A second aspect of the present invention is characterized in that, in the first aspect, the concavo-convex layer is made of a single-layer or double-layer laminated paper. The concavo-convex layer is formed of one layer or two layers by partially sealing the metal wire or the plastic wire on the cylinder wire of the paper machine or the cylinder wire at the stage of papermaking.

[0011] The invention of claim 3 is based on claim 2, and the gist is that two layers are laminated and one layer is flat and another layer has an uneven layer. The gist of the invention of claim 4 is that, in any one of claims 1 to 3, the filler is mixed in the uneven layer.

The filler refers to a filler such as clay, talc, kaolin, calcium carbonate, titanium oxide, white carbon, or the like. When the filler is mixed, the filler has a high oil absorption and further increases the transparency after use. .

[0013] The invention of claim 5 is the invention of claims 1 to 4.
Paper density is 0.7 to 1.2 g /
The gist is cm ³ . 0.7-1.
When the content is in the range of 2 g / cm ³ , the oil absorption is high, and the transparency is extremely increased after use. When the paper density is less than 0.7 g / cm ³ , the transparency after use becomes poor, and the paper density becomes 1.2 g / cm ^3.
Exceeding the range is not preferred because production becomes difficult.

The invention according to claim 6 is any one of claims 1 to 5.
In any of the above, the gist is that gold powder is mixed in the surface layer of the paper. By scattering the gold powder on the surface of the cosmetic fat removing paper, it is possible to obtain a decorative fat removing paper having a design like a high-grade salt paper through a gold foil process.

The invention according to claim 7 is a method for producing a paper net having a meridian of 0.1 to 1. The gist of this invention is a grease-absorbing paper for cosmetics in which an uneven layer is formed using 5 to 40 mesh at 0 mm. Wire diameter 0.1mm to 1. In the range of 0 mm, and 5 mesh ~
It is preferable to use a netting in the range of 40 mesh in terms of the oil absorption by the uneven layer and the formation of the paper layer. A wire diameter of less than 0.1 mm is not preferable because the oil absorption does not increase.
If it exceeds 0 mm, it is not good in terms of paper layer formation and strength.
Further, if the mesh size is less than 5 mesh, it is not preferable in terms of oil absorption,
If it exceeds 40 mesh, an uneven layer cannot be formed, which is not preferable.

In a preferred embodiment of the invention, the raw material mainly composed of vegetable fiber is made by a paper machine, and an uneven layer is formed on one or both sides of the net by the paper making machine. The gist is a paper manufacturing method.

(Production method) The raw material is at least 50% by weight of at least one selected from bast fiber or wood pulp composed of manila hemp, flax, jute, sisal, kenaf, ganpi, kozo, banana fiber or mitsumata. It is desirable to use. If the amount is less than 50 parts by weight, it is not preferable in terms of removing fats during use.

The mixture is adjusted to a predetermined beating degree with a beating machine such as a beader, and 0.5 to 40 parts by weight of an inorganic filler such as talc is mixed and uniformly dispersed. And if you make the paper as it is,
The filler fixation to the fiber is poor, causing drainage problems and process contamination.
Using C104 and Filex M (both manufactured by Meisei Chemical Industry Co., Ltd.), etc., the fixability to fibers is improved. After that, a wire-making machine such as a round-net paper machine, a short-net paper machine, or a fourdrinier paper machine having a wire diameter of 0.1 to 1. One layer of corrugated paper is formed by forming a layer of corrugated paper in a mesh pattern using 5 mm to 40 mesh of 0 mm, or by partially filling the mesh of the paper making net with no raw material. Can be formed.

Further, in the case of two layers, two sheeting tanks are used, and as in the case of one layer, as shown in FIG.
0 is formed. In the case of two-layer mixing, the first tank uses a wire mesh of 60 to 120 mesh to form a layer (smooth layer) 22 without an uneven layer. 1
~ 1. The uneven layer 21 is formed by using 5 to 40 mesh with 0 mm or partially filling the mesh of the wire mesh, and the basis weight is 1
Paper of 5 to 25 g / m ² is made (see FIG. 1 (b)).

In the case of less than the basis weight 15 g / m ^2, without the strength of the paper, tend to cause torn during use, also eliminates the flexibility exceeds 25 g / m ^2, familiar poor incompatibility with when using skin Yes, and more preferably 25 g / m ² or less in order to increase transparency during use.

The inorganic filler used can be selected from clay, talc, kaolin, calcium carbonate, titanium oxide and white carbon. To increase the oil absorption of sebum, use micro talc. Used, average particle size 2.5μ or less, surface area 13.0 BET
Those having m ² / g or more are desirable.

To increase the transparency after use, the density should be 0.7.
It is necessary to increase the density to １．２1.2 g / cm ^3, and after cutting to a predetermined size, several hundred to several thousand treatments are performed in the foiling step. There is also a method of improving the density of the paper by using a super calender, a high-pressure press or the like instead of the foil stamping step.
