The specific embodiment

［ the 1st embodiment ］

The 1st embodiment is a kind of cosmetics impregnation sheet, it is the fibrage that forms of the fibrous material that will contain the impregnation cosmetics and prevents that the hydrophobic film that cosmetics evapotranspire is laminated, be provided with for by fibrage and the stacked hot pressing section of hydrophobic film part, and, on hydrophobic film in this hot pressing section, be provided with the peristome connected towards fibrage.

More specifically, as Fig. 1 (a) or (b), the hydrophobic film 14 of the fibrage 12 of regulation and regulation under the state through stacked by the part hot pressing, to draw the mode of the Pareto diagram of stipulating, form a plurality of hot pressing 18(of section in order with reference to understanding, to have place, describe hot pressing section with dotted circle), and can between hydrophobic film 14 and fibrage 12, obtain appropriate cementability.

Then, corresponding with a plurality of hot pressing section 18 in hydrophobic film 14, be formed with respectively the peristome 16 of regulation, thereby the part of the hydrophobic film of heat fusing 14 flows out to the edge 16a of described peristome 16 on one side, with fibrage 12, engage on one side, performance is as the function of hot pressing section 18, and the existence of peristome 16 adjusted flexibility, the product having shape-following-up properties of hydrophobic film 14 and even cosmetics impregnation sheet 10, makes them become good.

Below, suitably with reference to accompanying drawing, specifically describe the cosmetics impregnation sheet as the 1st embodiment of the present invention.

1. hydrophobic film

(1) kind

Kind as hydrophobic film, be not particularly limited, the hydrophobic film that particularly, can use independent one or more the combination in mylar, polyurethane resin, vistanex, polyamide, fluororesin, silicone resin, phenoxy resin etc. to form.

And, more preferably use the hydrophobic film formed by pet resin or polyurethane resin.

The versatility that this reason is not only this hydrophobic film is high, favourable at economic aspect, and is the cosmetics impregnation sheet that has intensity and these two kinds of character of flexibility concurrently by using these hydrophobic films, can accessing.

Should illustrate, in the past, there was following problem in the pet resin film: easily produce pin hole etc. during due to masking, so thickness is that the following film forming of 5 μ m is more difficult, and can't be for the facial mask that requires good flexibility, product having shape-following-up properties etc.

Yet, according to the present invention, use the pet resin film of specific thickness, and form the peristome of regulation, thus can access there is prescribed strength and flexibility, the hydrophobic film of product having shape-following-up properties excellence.

In addition, in the situation that use the hydrophobic film formed by polyurethane resin, can access the cosmetics impregnation sheet that extremely is imbued with retractility.

Should illustrate, in the past, there was following problem in urethane resin film: produce pin hole etc. during due to masking or lack mechanical strength, so thickness is the following film forming difficulties of 10 μ m, and can't be for the facial mask that requires good flexibility etc.

Yet, according to the present invention, use the urethane resin film of specific thickness, and form the peristome of regulation, thus can access there is prescribed strength and flexibility, the cosmetics impregnation sheet of product having shape-following-up properties excellence.

In addition, as shown in Figure 2 (a) shows, hydrophobic film 14 can consist of a kind of film, but, as shown in Fig. 2 (b), also preferably a plurality of

film

14a, 14b, 14c is combined and formation hydrophobic film 14.

For example, in the situation that, as facial mask, preferably as the hydrophobic film 14b of facial mask central portion, use the urethane resin film of flexibility and retractility excellence, and, as hydrophobic film 14a, the c of left and right, use the pet resin film of mechanical strength, durability excellence.

(2) thickness

In addition, for the thickness of hydrophobic film, also can consider cosmetics the preventive of evapotranspiring, mechanical strength or peristome formative etc. and determine, but usually preferably be made as the value in the scope of 0.1～50 μ m.

This reason is the interior value of scope of above-mentioned thickness if, can effectively prevent evapotranspiring of cosmetics, and can form flexibility, the mechanical strength of regulation, or precision forms peristome well.

Therefore, preferably the thickness of hydrophobic film is made as to the value in the scope of 1～30 μ m, further preferably is made as the value in the scope of 2～20 μ m.

Wherein, preferably according to the kind of hydrophobic film, change its thickness.

For example, in the situation that use the pet resin film, preferably its thickness is made as to the value in the scope of 0.1～15 μ m.

This reason is, in the situation that use the pet resin film, if thickness is the value that is less than 0.1 μ m, exists and be difficult to be shaped to membranaceous situation uniformly.On the other hand, if above-mentioned thickness surpasses 15 μ m, exist flexibility to descend or be difficult to the situation that precision forms peristome well.

Therefore, in the situation that use the pet resin film, preferably its thickness is made as to the value in the scope of 0.5～6 μ m, more preferably is made as the value in the scope of 1～3 μ m.

In addition, in the situation that use urethane resin film, preferably its thickness is made as to the value in the scope of 5～30 μ m.

This reason is, if when the thickness of polyurethane resin becomes the value that is less than 5 μ m, exist be difficult to be shaped to membranaceous and be difficult to obtain the situation of sufficient mechanical strength, operability uniformly.

On the other hand, if when above-mentioned thickness surpasses 30 μ m, exist retractility, product having shape-following-up properties to descend, be difficult to effectively be attached at the situation of the irregular three-dimensional part of tool.

Therefore, in the situation that use urethane resin film, preferably its thickness is made as to the value in the scope of 7～25 μ m, more preferably is made as the value in the scope of 10～20 μ m.

(3) hydrophobicity

In addition, as the hydrophobic target in hydrophobic film, the contact angle that preferably will measure according to the JIS K 6768 of hydrophobic film (is measured temperature: 25 ℃, measure sample: pure water) be made as the value more than 60 °.

This reason is, contact angle by the hydrophobic film that will measure under rated condition is made as the value in above-mentioned scope, can effectively prevent from evapotranspiring to air containing the cosmetics that are immersed in fibrage, during as facial mask, can supply with cosmetics to skin fully and in Long time scale at the impregnation sheet that makes to apply some make up.

More specifically, if when the contact angle of hydrophobic film becomes the value that is less than 60 °, exist cosmetics excessively to evapotranspire to airborne situation, and have the situation of the impregnation sheet that is difficult to make to apply some make up in Long time scale.

But, if when the contact angle of hydrophobic film becomes excessive, have the situation that kind is restricted or spendable cosmetics are restricted of spendable hydrophobic film.

Therefore, more preferably the contact angle of hydrophobic film is made as to the value in the scope of 65～95 °, further preferably is made as the value in the scope of 70～90 °.

(4) Surface Machining

In addition, also preferably utilize Surface Machining (embossing processing etc.) to apply relief pattern on the surface of hydrophobic film.

This reason is, the embossing processing of stipulating by enforcement, can further improve flexibility, retractility while making to apply some make up the impregnation sheet, or adjusts the size of peristome and make the cosmetics preventive of evapotranspiring reduce or improve.

2. hot pressing section

(1) peristome

In addition, as shown in Fig. 1 (a), it is characterized in that, in order moderately to engage hydrophobic film 14 and fibrage 12, a plurality of hot pressing section 18 is set, corresponding with it, the peristome 16 connected towards fibrage 12 is set on hydrophobic film 14.

This reason is that by the hot pressing section with hydrophobic film, corresponding a plurality of positions arrange respectively the peristome of regulation, can regulate flexibility, the product having shape-following-up properties of hydrophobic film itself, and even flexibility, the product having shape-following-up properties of cosmetics impregnation sheet.

Therefore, even while utilizing pet resin film etc. as hydrophobic film, in the situation that as facial mask etc., also can access good use sense.

And, by with hot pressing section, peristome being set accordingly, can improve sense of vision.That is, when use does not have the hot pressing section of peristome, can produce variable color, distortion etc., easily damage the attractive in appearance of cosmetics impregnation sheet.

(2) the configuration pattern of peristome

In addition, for the configuration pattern of a plurality of peristomes, also be not particularly limited, for example, it can be the clathrate shown in Fig. 1 (b), although perhaps not shown, can be also zigzag, linear pattern wire, river shape, helical form, concentric circles, and irregular pattern.

Wherein, in the situation that the configuration pattern of a plurality of peristomes is made as to clathrate or other regular patterns as shown in Fig. 1 (b), following advantage is arranged: regulate the aperture of aftermentioned peristome, in abutting connection with distance, be easy to regulate flexibility, the product having shape-following-up properties of hydrophobic film and even cosmetics impregnation sheet.

On the other hand, may not form peristome 16 whole of hydrophobic film 14, also preferably selection is wished the position of good flexibility, product having shape-following-up properties and is formed.

For example, preferably be made as following mode, as shown in Fig. 3 (a), by hydrophobic film 14 ' third-class upper area 14a ', central region 14b ', lower area 14c ' of being divided into, only upper area 14a ' and lower area 14c ' formation peristome 16 ', and central region 14b ' do not form peristome 16 '.

Perhaps, preferably be made as following mode, as shown in Figure 3 (b), by hydrophobic film 14 " the third-class upper area 14a that is divided into ", central region 14b ", lower area 14c ", only at central region 14b, " form peristome 16 ", and do not form peristome 16 at upper area 14a " and lower area 14c " ".

Should illustrate, on the basis of the configuration pattern of determining peristome, as shown in Figure 4, distance in the heart in the peristome of adjacency, be that the spacing size of peristome becomes problem, preferably the spacing of this peristome (d2) is made as to the interior value of scope of 0.5～20mm.

; when if the spacing of peristome (d2) becomes the value that is less than 0.5mm; the width of the hydrophobic film between the peristome of adjacency becomes too small; otherwise perhaps; the aperture of the peristome that can exist becomes too small, exists and is difficult to regulate hydrophobic film, the flexibility of cosmetics impregnation sheet, the situation of product having shape-following-up properties.

On the other hand, when if the spacing of peristome (d2) becomes over the value of 20mm, the width of the hydrophobic film between the peristome of adjacency becomes excessive, otherwise perhaps, the aperture of the peristome that can exist becomes excessive, and same the existence is difficult to regulate hydrophobic film, the flexibility of cosmetics impregnation sheet, the situation of product having shape-following-up properties.

Therefore, more preferably the spacing of peristome (d2) is made as to the interior value of scope of 1～10mm, more preferably the value in the scope of 2～5mm.

(2) flat shape of peristome

In addition, for the flat shape of peristome, also be not particularly limited, usually the arbitrary shape in circular, Long Circle, quadrangle, ellipse, rhombus, triangle, star-like, abnormity.

More specifically, as the shape of peristome 16, be preferably the circle as shown in Fig. 4 (a) or Figure 10 (a), quadrangle as shown in Figure 4 (b).

This reason is if having the peristome of this flat shape, can stably form, and can be easy to adjust flexibility, the product having shape-following-up properties of hydrophobic film and even cosmetics impregnation sheet.

And then, mode as aftermentioned embodiment, as shown in Figure 10 (b), if peristome 16 be shaped as Long Circle, can stably form, and can make the percentage elongation of broad ways in hydrophobic film 14 and even cosmetics impregnation sheet 10 and percentage elongation along its length there is anisotropy.

(3) aperture of peristome

In addition, preferably the aperture of peristome (d1) is made as to the interior value of scope of 0.05～3mm.

This reason is, if above-mentioned size, can in the situation that excessively do not reduce mechanical strength, the cosmetics of hydrophobic film 14 preventive of evapotranspiring, easily control flexibility, the product having shape-following-up properties of hydrophobic film and even cosmetics impregnation sheet.In addition, if above-mentioned size can obtain appropriate cementability between hydrophobic film and fibrage.

Therefore, more preferably the aperture of the peristome of hydrophobic film (d1) is made as to the value in the scope of 0.1～1mm, further the preferred value in the scope of 0.2～0.8mm.

Should illustrate, the aperture of peristome (d1) refers to the diameter (equivalent circle diameter) in the peristome of regulation shape.

Therefore, for example, as shown in Figure 4 (a), being shaped as in circular situation of peristome, diameter is directly aperture (d1), and as shown in Figure 4 (b), be shaped as in tetragonal situation, diameter refers to the diameter suitable with having circle of the same area (equivalent circle diameter).

And then the aperture of peristome (d1) may not be all identical whole of hydrophobic film 14, also preferred suitably the selection wished the position of good flexibility, product having shape-following-up properties and changed.

For example, preferably as shown in Figure 4 (c), by the hydrophobic film 14 " ' third-class upper area 14a that is divided into " ', central region 14b " ', lower area 14c " ', make upper area 14a " ' aperture (d1) minimum of peristome 16; then; make central region 14b " ' the aperture (d1) of peristome 16 become by comparison greatly, and then, make lower area 14c " ' the aperture (d1) of peristome 16 larger.

By above-mentioned formation, can make from top the hydrophobic film 14 that flexibility, product having shape-following-up properties downwards become good gradually " '.

(4) edge of peristome

In addition, preferably, as shown in Fig. 1 (a) and (b) etc., the overshooting shape edge 16a with specified altitude and Rack is set around peristome 16.

This reason is, utilizes the overshooting shape edge of above-mentioned peristome, can effectively prevent that cosmetics from flowing out to beyond the regulation place.

Therefore, particularly, preferably the height at peristome edge is made as to the value in the scope of 0.05～5mm, more preferably is made as the value in the scope of 0.1～3mm, further preferably be made as the value in the scope of 0.2～2mm.

In addition, the value in the same scope that preferably width at peristome edge is made as to 0.01～1mm, more preferably be made as the value in the scope of 0.05～0.5mm, further preferably is made as the value in the scope of 0.08～0.2mm.

Should illustrate, the height at peristome edge, width can easily be controlled by heating-up temperature, squeeze pressure or the extrusion speed (translational speed of fibrage and hydrophobic film) etc. of adjusting spicule.

But, in the situation that do not need the peristome edge, preferably utilizing hot pressing etc., heat and the pressure of additional regulation, make the edge of above-mentioned peristome smooth.

(5) the individual number density of peristome

In addition, preferably the individual number density of peristome (have density or have ratio) is made as to 2～70/cm ²scope in value.

This reason is, if the individual number density of peristome is for being less than 2/cm ²value the time, have following situation: flexibility, the product having shape-following-up properties of hydrophobic film and even cosmetics impregnation sheet significantly lack or hydrophobic film and fibrage between cementability descend.

On the other hand, if the individual number density of peristome surpasses 70/cm ²the time, exist and be difficult to stably to form peristome or excessively reduce the evapotranspire situation of preventive of cosmetics.

Therefore, more preferably the individual number density of the peristome of hydrophobic film is made as to 20～65/cm ²scope in value, further preferably be made as 30～60/cm ²scope in value.

Should illustrate, the individual number density of a plurality of peristomes may not be all identical whole of hydrophobic film, and also preferred suitably the selection wished the position of good flexibility, product having shape-following-up properties and increase above-mentioned number density.

(6) area ratio of peristome

In addition, preferably by the area ratio of hydrophobic film split shed section, in the per unit area of hydrophobic film (100%), the ratio of the total area of a plurality of peristomes is made as 1～30% the interior value of scope.

This reason is, if the area ratio of peristome is while being less than 1% value, has the situation that is difficult to process hydrophobic film and even cosmetics impregnation sheet.

On the other hand, if when the area ratio of peristome surpasses 30%, exist and be difficult to stably to form peristome or excessively reduce the evapotranspire situation of preventive of cosmetics.

Therefore, more preferably the area ratio of hydrophobic film split shed section is made as to the value in 5～25% scope, further preferably is made as the value in 7～20% scope.

Should illustrate, the area ratio of a plurality of peristomes may not be all identical whole of hydrophobic film, and also preferred suitably the selection wished the position of good flexibility, product having shape-following-up properties and increase above-mentioned area ratio.

(7) side view of peristome

In addition, for the side view of peristome, also be not particularly limited, but preferably as shown in Fig. 5 (a), make column, or, as shown in Fig. 5 (b), make from pressing section and become large taper to the peristome aperture.

This reason is, if the side view of above-mentioned column or taper, can use the stable and precision of the spicule etc. of heated condition to form well.

3. fibrage

(1) fibrous material

In addition, as the kind that forms fibrolaminar fibrous material, be not particularly limited, but such as independent one or more the combination in preferably cotton, paper pulp, real silk, staple fibre, CUP, polyester, polyamide, polyacrylic acid, polyolefin, polyvinyl alcohol, polyvinyl chloride, polypropylene, day thread (Lyocell) etc.

And, as described below, be preferably that to contain contact angle be the hydrophilic fiber layer that the following hydrophilic fiber material of setting forms.

That is, if this hydrophilic fiber layer can merge and impregnation fully mutually with cosmetics, and can stably keep, in the situation that, as uses such as facial masks, can in Long time scale, obtain good use sense.

In addition, contain the fibrage that fibrous material forms so long as there is the tablet of flexibility, product having shape-following-up properties, just be not particularly limited, but for example preferably textile thing, braid, nonwoven, stationery.
