Abstract

PURPOSE:To substantially prevent unraveling of fibers and to eliminate the trouble that the fibers remain on the skin after use by using acetyl cellulose filaments having specific single yarn fineness as constituting blank materials and applying mechanical intercrossing means of a specific METSUKE (unit) weight thereto. CONSTITUTION:The acetyl cellulose filaments having 1.5 to 5.0 denier single yarn fineness are used as the constituting blank materials and are subjected to the mechanical intercrossing means of 20 to 200g/m<2> METSUKE (200-2000g/m<2>) weight. The puff for cosmetics which prevents the removal of the filaments, allows the good removal of cosmetic stains and has a good touch to the skin is thereby obtd. The mechanical intercrossing means is executed by taking off the acetyl cellulose dope spun out of plural dry spinning cylinders 1 by a godet roller 3 via a bundling guide 2 and spraying this dope uniformly by a nozzle gun 4 to a screen conveyor 5, then spraying low-pressure water in a columnar form from a water spraying machine 6. High-pressure water is then from a water jet manihold 7 to intercross the filaments; thereafter, the filaments are processed by dehydrating rolls 8, a drying machine 9 and a calender 10 and are taken up on a take-up machine 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic puff used when applying a lotion or removing makeup.

[0002]

2. Description of the Related Art Conventionally, as a puff used when applying a lotion or removing makeup, a laminated web of degreased cotton called absorbent cotton or artificial fiber such as rayon in place of cotton is used. There are those in which a web made of the above is used, and the surface of these webs is covered with a non-woven fabric.

[0003]

In the conventional web puff, the fibers are not tightly entangled with each other, so that the fibers easily come off and the fibers on the surface peel off from the main body when rubbed with a little force when used for makeup removal. There was a problem that it remained on the skin and the makeup did not clean well.
Therefore, a web with the surface of the web covered with a non-woven fabric has also been developed.
The feeling of use and the stains on makeup were insufficient.

The present invention has been made to solve such problems, and by using a specific non-woven fabric,
It provides a puff that does not come out of fibers, cleans up the makeup, and feels good against the skin.

[0005]

Means for Solving the Problems The present invention uses a mechanical entanglement means having a basis weight of 20 to 200 g / m ² and using acetyl cellulose filaments having a single yarn fineness of 1.5 to 5.0 denier as a constituent material. The present invention provides a cosmetic puff made of a non-woven fabric.

In the present invention, the material constituting the non-woven fabric is acetyl cellulose filament having a single yarn fineness of 1.5 to 5.0 denier, preferably 2.0 to 4.0 denier. When the single yarn fineness is less than 1.5 denier, the single yarn strength is low and fluffing occurs due to single yarn breakage. On the other hand, 5.
When it exceeds 0 denier, it becomes inflexible and becomes stiff, and the feel on the skin is not good. In addition, there is a problem that an adhesive is required when manufacturing a nonwoven fabric.

Although the degree of acetylation of acetyl cellulose is not particularly limited, it is usually 10 to 62.5%,
It is preferably 53.0 to 57.0%. This is because if the degree of acetylation is too low, the equilibrium moisture content becomes high and you feel a sticky discomfort.On the other hand, if it is too high, the equilibrium moisture content becomes low and the hygroscopicity becomes poor, resulting in poor texture. is there. The basis weight of the non-woven fabric made of such materials is 20 to 200 g / m ² , preferably 60 to 100 g.
/ M ² . If it is less than 20 g / m ^2, it is too thin and the strength is weak even if it is laminated in several layers, which is not preferable. On the other hand, 200
If it exceeds g / m ² , it is too thick and stiff, and it feels hard and does not feel good to the touch.

The nonwoven fabric used in the present invention must be provided with a mechanical entanglement means. As a result, the fibers are less likely to fray and the fibers do not remain on the skin after use. In addition, when used for removing makeup, dirt is taken in the mesh formed by the entanglement and comes to fall off well. In addition, since it has a good shape retention property, it is easy to use and feels good to the touch even if it is soaked with lotion, or it is used by putting it between fingers when it is used for removing makeup and rubbing with some force.

Any method may be used for applying the mechanical entanglement means, and for example, a jet bond method may be used. An example of a method for manufacturing a nonwoven fabric by such a jet bond method will be described with reference to FIG. That is, acetyl cellulose dope prepared by dissolving acetyl cellulose flakes in acetone is spun out from each of a plurality of dry spinning cylinders 1, and these are taken up by a gusset roller 3 via a focusing guide 2, and this is taken from a nozzle gun 4 by a screen conveyor 5 Spray evenly on.

Next, 0.1 to 0.15 kg from a sprinkler 6 having a thin nozzle of 0.08 to 0.15 mm.
Spray water columnar at a low pressure of / mm ² . This is because the fibers sprayed on the screen conveyor are disturbed by high-pressure water, resulting in uneven thickness. Full-scale entanglement is performed by injecting a high-pressure columnar flow of about 0.5 kg / mm ² from the water jet manifold 7. The jet injection hole (not shown) of the water jet manifold 7 has a diameter of 0.1 m.
m, arranged at a density of 25 to 30 holes / inch. After that, it is dehydrated by a dehydrating roll 8 and then dried by a drier 9, calendered by a calender 10, and wound by a winder 1.
Roll in 1.

The shape of the resulting non-woven fabric of acetyl cellulose filaments is determined by the material of the screen, the thickness of the net thread, and the structure, and these are not limited, but usually the number of meshes, that is, the mesh is 70. ~ 100
It is about mesh / cm ² , and the wire mesh is made of stainless steel or bronze, and flat, 2/1, 1/2, 2/2 diagonal and ridge structures are used.

The thus obtained non-woven fabric used in the present invention does not use an adhesive, and other fibers are twisted and bent around the fibers by the impact force of the jet water to form a small bundle. The mechanical entanglement means with increased strength is applied to form a cloth, and contains no substance other than acetyl cellulose. The whiteness is very high, it has a refreshing feeling as a material for a cosmetic puff, and when it is used for removing stains, it has an effect that stains can be clearly seen, and is excellent as a stain remover.

The cosmetic puff of the present invention can be obtained by laminating such a nonwoven fabric and cutting it into a predetermined size. At the time of cutting, it can be easily manufactured by thermal fusing.

The cosmetic puff of the present invention uses the acetyl cellulose long fiber non-woven fabric which has been subjected to such mechanical entanglement means, and is used not only in the laminated form as described above but also in the conventional puff. Cotton wool, artificial fiber,
For example, the surface of a web of acetate filament, rayon, polyester or the like may be wrapped with this nonwoven fabric.

Further, a laminate of this non-woven fabric may be covered with an ordinary non-woven fabric. Furthermore, such an acetyl cellulose nonwoven fabric may be used as a core, and the outer surface may be covered with a foam to be used as a puff used when applying a foundation to the face.

[0016]

In the present invention, since the entangled acetyl cellulose nonwoven fabric is used as the cosmetic puff, the fibers are less likely to be frayed, so that the fibers do not remain on the skin after use. Moreover, since the fibers and the mesh of the fibers are firmly formed by the entanglement, the dirt is well taken in because the dirt is taken into the mesh when used as a makeup remover.

[0017]

The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples. Example 1 Acetylcellulose Flakes 50 having a degree of acetylation of 54.7%
0 kg was dissolved in 1,580 kg of acetone to prepare a dope, and a nonwoven fabric was manufactured according to the apparatus shown in FIG. That is, acetyl cellulose dope is spun out from each of the plurality of dry spinning cylinders 1, and the focusing guide 2 and the gozette roller 3 are used.
After that, it was sprayed uniformly on the screen conveyor 5 from the nozzle gun 4.

After that, columnar water was sprayed on this from a water sprinkler 6 having a nozzle having a diameter of 0.1 mm at 0.1 kg / mm ² . After that, jet manifold 7 to 1.5k
A high-pressure columnar water stream of g / mm ² was jetted and entangled. At this time, the jet injection holes used had a diameter of 0.5 mm and were arranged at a density of 25 holes / inch.

The single filament fineness of the acetyl cellulose filaments constituting the nonwoven fabric thus obtained was 3.0 denier, and the basis weight of the nonwoven fabric was 70 g / m ² .

The thus obtained non-woven fabric subjected to the mechanical entanglement means was laminated in multiple layers and heat-cut into a 5 × 6 cm square to produce a cosmetic puff. The obtained cosmetic puff had a good texture and a high whiteness. When used as a makeup remover, the stains were well removed and no fibers remained on the skin.

[0021]

EFFECTS OF THE INVENTION The cosmetic puff according to the present invention has good touch and
It has a high degree of whiteness and has a refreshing feel, with no fibers remaining on the skin after use and good stain removal.
