DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the body cleaning sheet of the present invention has a structure in which an oily substance absorbing layer 1, an aqueous cleaning liquid holding layer 2, and a non-liquid permeable layer 3 provided therebetween are laminated. Have. In this case, it is preferable that at least adjacent layers (that is, the oil-based substance absorbing layer 1 and the non-liquid-permeable layer 3, and the non-liquid-permeable layer 3 and the aqueous cleaning liquid holding layer 2) contain the same kind of thermoplastic substance. When adjacent layers contain the same kind of thermoplastic material, both layers can be firmly bonded by thermal fusion. Here, “the same kind of thermoplastic substance” means substances having similar thermoplastic resin component structures (main structures are identical) and exhibiting good compatibility with each other.
[0011]
The oily substance absorbing layer 1 is a layer for absorbing and removing oily dirt, and is composed of an oily substance absorbing nonwoven fabric. Preferably, it is comprised from the nonwoven fabric dry sheet formed from the filament of the lipophilic thermoplastic resin.

[0014]
Moreover, it is preferable that many fine holes are formed in the oily substance absorption layer 1 in order to increase the absorption surface area of the oily dirt. As a method for forming a large number of micropores in the oily substance absorbing layer 1, it is preferable to use a melt blown method, which is a kind of nonwoven fabric manufacturing method, in that the touch to the skin (use feeling) during use can be improved. Specifically, when melt spinning a thermoplastic resin, a high-temperature and high-pressure air stream is blown to the outlet of the spinning nozzle to draw and open the fibers immediately after spinning to form ultrafine fibers, and the ultrafine fibers are collected. The fine holes may be formed by stacking on a conveyor to form a sheet, and then thinning by heat embossing, calendaring, or the like. In particular, by performing the calendar process, it is possible to make the light transmittance between the portion where the oily dirt is absorbed and the surrounding area different, and it is possible to visually confirm whether or not the oily dirt is absorbed.
[0015]
The thickness of the oily substance absorption layer 1 is 10 to 300 μm, preferably 20 to 200 μm.
[0016]
The aqueous cleaning liquid holding layer 2 is a layer for wiping off or absorbing and removing aqueous dirt, and is constituted by holding an aqueous cleaning liquid on an aqueous cleaning liquid holding nonwoven fabric. Here, as a grade of holding | maintenance of aqueous | water-based cleaning liquid, Preferably it is 100 to 500 weight% with respect to an aqueous | water-based cleaning liquid holding | maintenance nonwoven fabric.

[0019]
As the aqueous cleaning liquid in the aqueous cleaning liquid holding layer 2, known lotions, cleaning liquids, emulsions and the like can be used, and it is particularly preferable to contain sebum-dissolving components such as ethanol and an aqueous surfactant solution.
[0020]
Furthermore, it is more preferable that the aqueous cleaning liquid contains an insoluble powder that imparts a smooth feeling to the skin and makes the user feel a fresh feeling as if the face was washed.
[0021]
As the insoluble powder, various powders that are insoluble in the aqueous cleaning liquid constituting the aqueous cleaning liquid holding layer 2, the oily dirt on the skin surface, and the aqueous dirt can be used. For example, inorganic powder such as silica, alumina, talc, kaolin, mica, titanium mica, zeolite, gunjo, zinc white, iron oxide, nylon, vinyl polymer, dimethyl silicone cross-linked elastomer, polymethyl methacrylate, methacrylate-alkylene diene An organic powder made of a polymer such as a methacrylate copolymer can be used. These insoluble powders may be porous or non-porous. In particular, it is possible to maintain a good skin feel and a smooth feeling by using a mixture of a powder that improves the skin feel and imparts a smooth feeling and an oil-absorbing powder such as a porous polymer or silica. This is preferable.
[0022]
As a preferable particle diameter of the insoluble powder, the average particle diameter is preferably 1 to 30 μm in order to obtain a good skin feel.
[0023]
In order to spread such an insoluble powder on the skin, it is preferable to reduce the voids (that is, the average pore diameter) of the aqueous cleaning liquid retaining nonwoven fabric to about 1 to 30 μm. In order to reduce the voids, it is preferable to form the aqueous cleaning liquid retaining nonwoven fabric from ultrafine fibers such as pulp and rayon, acrylic fibers and rayon fibers that are easily fibrillated and divided.
[0024]
The thickness of the aqueous cleaning liquid retaining layer 2 is 100 μm to 5 mm, preferably 500 μm to 1 mm.
[0025]
The non-liquid permeable layer 3 is a layer for preventing the aqueous cleaning liquid that constitutes the aqueous cleaning liquid holding layer 2 from seeping into the oily substance absorbing layer 1 (show-through). This is a layer that does not move the absorbed oily dirt to the aqueous cleaning liquid holding layer 2 side. The non-liquid-permeable layer 3 is preferably composed of a soft material sheet or film for the purpose of improving the feeling of use of the body cleaning sheet. For example, polyolefin such as polyethylene, polypropylene, polyethylene-polypropylene blend polymer, etc. Polyester resin such as polyethylene terephthalate and polybutylene terephthalate; Polyvinyl chloride resin; Polyamide resin such as nylon; Polyacrylic resin such as ethyl ethyl acrylate; Polyurethane resin; Cellulose resin; Polylactic acid Examples thereof include a sheet or film of a thermoplastic resin such as a resin. Furthermore, additives can be appropriately added to these thermoplastic resin sheets or films for the purpose of improving lipophilicity or improving softness. Examples of such additives include liquid rubber such as butadiene oligomer and isoprene oligomer, petroleum resin, coumarone resin, chlorinated paraffin, silicon oil, liquid paraffin, polyethylene wax and the like.

The aspect comprised from the wet hydroentanglement nonwoven fabric (component fiber = acrylic short fiber, pulp) which mixed the core sheath composite short fiber (core polypropylene; sheath polyethylene) can be mentioned. Here, if the mixing ratio of the core-sheath composite fiber to the wet hydroentangled nonwoven fabric is too small, the adhesiveness between the aqueous cleaning liquid retaining layer and the liquid-impermeable layer is insufficient, and if it is too large, the aqueous cleaning liquid retaining layer is insufficient. Since it becomes hard and the touch is deteriorated, it is preferably 10 to 30% by weight. According to this aspect, in normal use, there is no peeling between the respective layers, and the whole can be made thin, and the usability is improved.
[0027]
Moreover, in order to make it easy to visually recognize that the body cleaning sheet of the present invention has absorbed oily dirt, each layer may be colored. In this case, it is preferable to make the colors of the respective layers different from each other, in particular, to darken the color of the liquid-impermeable layer so that the contrast can be easily obtained.
[0028]
The body cleaning sheet of the present invention shown in FIG. 1 is formed by laminating an oily substance-absorbing nonwoven fabric, a non-liquid-permeable thermoplastic resin film, and an aqueous cleaning fluid-retaining nonwoven fabric using, for example, a hot melt adhesive. Thereafter, the aqueous cleaning liquid-retaining nonwoven fabric can be produced by spraying and holding the aqueous cleaning liquid. By spraying and holding the aqueous cleaning liquid in this manner, the powder can be efficiently present on the surface of the aqueous cleaning liquid holding nonwoven fabric.

It is preferable to spray and hold the aqueous cleaning liquid. Accordingly, the same kind of thermoplastic substance may be contained in the oily substance-absorbing nonwoven fabric, the non-liquid-permeable thermoplastic resin film, and the aqueous cleaning liquid-retaining non-woven fabric at the same time. The same kind of thermoplastic substance (first thermoplastic substance) is contained in the thermoplastic resin film, and another non-liquid-permeable thermoplastic resin film and an aqueous cleaning liquid-retaining non-woven fabric are separated from the same kind of thermoplastic substance (first 2 thermoplastic materials). In this case, the liquid-impermeable thermoplastic resin film simultaneously contains the first thermoplastic material and the second thermoplastic material.
[0030]
In addition, when laminating each layer, the adhesion between each layer may be performed on the entire opposite surface, but in order to give good softness and feeling of use to the body cleaning sheet, it may be partially adhered. preferable.
[0031]
The body cleaning sheet of the present invention is usually stored and stored in a sealed bag, and the body cleaning sheet is taken out from the sealed bag and used at the time of use. For example, oily dirt such as sebum that has floated on the surface of the body (skin, hair, makeup) is absorbed and removed on the oily substance absorbing layer side, and aqueous dirt is removed on the aqueous cleaning liquid holding layer side. Therefore, according to the body cleaning sheet of the present invention, by using the front and back of one sheet, oily stains and aqueous stains floating on the body surface or the makeup surface can be easily removed without breaking the makeup. Can improve the durability of makeup.
[0032]
