Description

[Detailed explanation of the idea] This invention relates to cosmetic cotton.

Cosmetic cotton is mainly used to apply lotion, milky lotion, etc. to the face.

Therefore, since it comes into direct contact with the facial skin, the surface flexibility,
Good texture is essential, and it must have excellent liquid retention properties for lotions and other liquids, retain volume and flexibility when wet, have good shape retention when used, and have no fibers falling off from the surface. desirable.

As decorative cotton, generally used is absorbent cotton that has been laminated or cut, or one in which the surface of a hydrophilic fiber web such as absorbent cotton is covered with a nonwoven fabric or the like.

Since such conventional cosmetic cotton mainly uses hydrophilic fibers as a water-retaining material, once the lotion is squeezed out from the skin surface during use,
The disadvantage is that the fibrous web shrinks and loses its thickness, resulting in a marked decrease in the usability and loss of liquid retention.

In addition, although decorative cotton made by laminating and cutting absorbent cotton has an excellent texture, it has the disadvantage that the short fibers that fall off after use adhere to the skin.To prevent this, products whose surface is covered with non-woven fabric are also They have various problems, such as texture, misalignment between the absorbent body and the surface layer when wet during use, peeling, and poor overall shape retention.

The present invention eliminates the above-mentioned drawbacks and provides a cosmetic cotton that is comfortable to use, retains lotion, and has high efficiency in use.

That is, the present invention provides cosmetic cotton that essentially consists of a surface layer and an absorbent layer, in which the surface layer contains 70% or more (by weight, the same applies hereinafter) of heat-fusible fibers, and whose weight is 15 f/rd.
or less, and the absorbent layer is 40 to 75% hydrophilic fibers and 60%
~25% hydrophobic fibers, the hydrophobic fibers contain 5~20% heat meltable fibers in the absorbent layer, and the weight of the absorbent layer is 70~150g/y4, and the surface layer and absorbent layer are This relates to decorative cotton characterized by being integrated.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a perspective view of one embodiment of the decorative cotton of the present invention.
A cross-sectional view taken along line A-A in the figure is shown in FIG.

The decorative cotton 1 is composed of a surface layer 2, an absorbent layer 3, and a back layer 4, and the surface layer 2 and the back layer 4 are substantially the same.
It is also possible to omit the back layer 4.

The surface layer 2 is mainly composed of heat-fusible fibers.

The heat-melting fiber is a fiber that softens at 200°C or lower, and it is desirable to use polypropylene or ES fiber, which is a heat-melting binder fiber manufactured by Chitsuso Polypropylene Co., Ltd., or the like.

The amount of heat-fusible fibers in the surface layer 2 is at least 70%, preferably 80% or more, in order to prevent the fibers from falling off when the decorative cotton is used.

In addition, in order to prevent the deterioration of texture, the weight of the surface layer 2 should be 15
A web carded at 9/d or less, preferably 5 to 10 y/d is used.

The absorbent layer 3 consists of 40-75% hydrophilic fibers such as rayon, and 60-25% hydrophobic fibers such as polyester or nylon to maintain the volume when wet, and to prevent the absorbent layer from shifting or creaking. The above-mentioned hydrophobic fibers contain 5 to 20% of heat-fusible fibers based on the total fibers of the absorbent layer.

The weight of the absorbent layer is desirably 70 to 15 B/m, because if it is too small, the amount of liquid retained per use will be small, and if it is too large, the amount of liquid retained will be large and the layer will become unnecessarily thick.

What is important here is that the absorbent layer 3, the surface layer 2, and if there is a back layer 4, the whole is integrated, including the back layer 4.

This integration means that the layers that make up the decorative cotton will not separate even if the normal stress is applied when using the decorative cotton.The webs containing heat-fusible fibers are laminated and exposed to hot air. It can be manufactured by a known method such as exposing.

The decorative cotton of the present invention is constructed as described above, so even though the surface layer is mainly made of hydrophobic fibers, the weight is 1.
Since it is 51/d or less, it is thin, and since it is integrated with the absorbent layer, it is in close contact with the absorbent layer, so it does not interfere with the absorption of liquids such as lotion and emulsion.

Furthermore, the absorbent layer also contains 25 to 6 hydrophobic fibers including heat-fusible fibers.
Since it contains 0%, it has poor liquid retention under pressure, and when used, it easily releases the absorbed liquid.It also has a voluminous feel even when wet during use, so it does not have the squeaky feeling characteristic of hydrophilic fibers. Since the entire product is integrated, each layer does not shift or peel, making it an extremely easy-to-use cosmetic cotton.

FIG. 3 shows another embodiment of the present invention.

In this embodiment, a surface layer 2, an absorbent layer 3 and a back layer 4 are used.
is the same as the embodiment shown in FIG. 1, but a heat seal 5 is applied to its end.

Because the heat seal 5 exists, even if pressure is applied when using the cosmetic cotton 1, the liquid that was absorbed will be absorbed by the heat seal 5.
This has the advantage that it is not emitted to the sides beyond the point.

Of course, the heat seals 5 may be provided on all sides, and the shape is not limited to a quadrilateral, but can take various shapes such as tapering both ends to make it easier to use.

The present invention will be explained in more detail with reference to Examples below.

Examples 1-2. Comparative Examples 1 to 5 The surface layer was made of 100% ES fiber and weighed 10 g/d, and the absorbent layer was made of fiber composition shown in Table 1 with a weight of 100 g/rIl, and these surface layer and absorbent layer were integrally molded. Various types of decorative cotton were manufactured.

The physical properties of the obtained decorative cotton were tested by the following method.

The results are shown in Table 1. <Test method> Absorption amount test per 1 g Soak the cosmetic cotton in water for 3 minutes, hang it gently by the end, leave it for 3 minutes, measure the weight, and calculate the absorption amount per 1 g.

0. Water retention amount after pressurization per 1g Apply 3 to the cosmetic cotton whose absorption amount was measured above at a pressure of 15g/yf.
After applying pressure for a minute, the pressure was removed and the amount of water retained was measured.

○ Volume feeling after pressurization A sensory test was conducted using a cosmetic monitor.

A: It has a sense of volume. B: Slightly lacking in volume C: Poor sense of volume ○ Feel of laminate A sensory test was conducted using a cosmetic monitor.

A: Good feel B: Normal C: It feels rough and feels bad.
