Description

  TECHNICAL FIELD The present invention relates to a non-woven fabric three-dimensionally shaped facial pack mask and a method for producing the same.

  Conventionally, as a non-woven mask for a facial pack, a spunlace nonwoven fabric mainly composed of rayon fibers is punched out in a state of being cut along the three-dimensional shape when pasted on the face, In general, a method of impregnating and adhering to a face and using it as a beauty face pack is generally performed.

  However, since the nonwoven fabric mask described in Patent Document 1 uses a flat one for a three-dimensional face, it cannot sufficiently follow the unevenness of the face such as between the eyebrows, orbits, and around the nose, and a gap is generated between the face and the face, There is a problem that it is difficult to obtain a sufficient beauty effect in these parts requiring special care in terms of beauty.

  For example, a non-woven face pack mask 10 shown in FIG. 5 uses a spun lace nonwoven fabric 11 mainly composed of rayon fibers, and is impregnated with a cosmetic liquid so as to follow the face shape when applied to the face. A part provided with a notch 12 and a center part provided with a notch 13 covering the nose bridge part, and a part provided with punched holes 14 and 15 at the part corresponding to the eyes and mouth are implemented. When this mask is worn on the face, the notch 13 in the nasal bridge is folded at the center so that it is affixed to both sides of the nose, and the eyes and mouth are pressed with fingers and shaped to fit the shape of the face. However, since a flat surface is pasted on a three-dimensional face, it is easy to create a gap at the cut portion of the nose, and it is difficult to follow the unevenness of the face at the orbit, mouth, etc., and it is difficult to obtain a sufficient cosmetic effect. . In general, this type of mask often uses a relatively thin and soft mask to increase the degree of adhesion to the face. However, if the mask is worn for a long time because it is thin, the moisture content is low and it is easy to dry. There is also a problem that the part that has been pressed and pressed with a finger is shrunk and floats due to drying.

  As in the non-woven fabric mask described in Patent Document 2, some of the cut shapes have been devised so that they can easily follow the three-dimensional shape of the face, and some of them have been processed to be close to the three-dimensional shape by heat welding, Since the shape is composed of a set of planes, it was insufficient to eliminate the gap between the face and the face as described above.

  As a method for forming a nonwoven fabric, as introduced in Patent Document 3, a hot fiber spunbond nonwoven fabric made of a thermoplastic synthetic resin or a short fiber needle punched nonwoven fabric is preheated and heat-pressed with a match mold. Methods for molding are known. However, when a non-woven fabric mainly made of a thermoplastic synthetic resin is formed by the above method to form a three-dimensional shape suitable for the face and to be used as the facial mask used by impregnating a cosmetic liquid, long fibers Spunbond nonwoven fabrics and short fiber needle punched nonwoven fabrics can be molded in shape, but the structure is solidified to maintain the shape during heat molding, and the texture is tight with respect to the spunbond nonwoven fabric. Therefore, there is a problem that water retention is not sufficient. In short fiber needle punched nonwoven fabrics, water retention is superior to spunbonded nonwoven fabrics, but the binder fiber blended to maintain the shape melts and solidifies, resulting in countless minute solidification points on the surface of the molded product. There are various problems such as inferior feeling and irritation to the skin, and it has not been put into practical use.

  An object of the present invention is to provide a mask for a three-dimensionally-shaped facial pack that has a good feel and can be in close contact with a face without a gap, and a method for manufacturing the same.

  The mask for three-dimensionally molded facial pack according to the present invention uses a material cloth formed by integrating a nonwoven fabric for shape retention that can be hot-press-molded and a non-woven fabric made of rayon that has high water absorption and is comfortable to touch. Thus, it is formed by hot press molding into a mask shape covering the face.

  With this three-dimensional shaped facial pack mask, the shape along the face can be applied to the mask by hot press molding, so there is almost no gap along the facial irregularities that require beauty such as the eyebrows, orbits, and around the nose. A mask can be adhered. Moreover, since the non-woven fabric made of rayon that is soft and has a good touch is joined to the inside of the non-woven fabric for shape retention, the contact of the mask with the face can be made soft, and a feeling of use such as the touch can be sufficiently secured. For this reason, since the binder fiber of the molded nonwoven fabric is melted and solidified, it is hard and feels bad, so the nonwoven fabric molded product that was thought to be unusable as a mask for facial packs to be put on the skin of sensitive faces However, by comprising like this invention, it came to be able to utilize as a mask for beautiful face packs with the high adhesiveness with respect to the uneven | corrugated shape of a face, and the usability | use_condition.

Here, as a non-woven fabric for shape retention, a basis weight of 50 to 150 g obtained by hydroentangling a web formed by blending 15 to 60% of a low melting point binder fiber with respect to a fiber made of a thermoplastic synthetic resin. The use of a spunlace nonwoven fabric of / m ² is a preferred embodiment. Thus, the effect that the shape provided by shaping | molding is hold | maintained by mixing a binder fiber is acquired. In addition, when the blending ratio of the binder fiber is less than 15%, there is a problem that the shape cannot be sufficiently maintained, and when it exceeds 60%, the structure becomes too hard and the flexibility of the shape is not good. It is preferable to set it to 60%. In addition, the basis weight of the shape retention nonwoven fabric made of spunlace nonwoven fabric is less than 50 g / m ² , and there is a problem that the shape cannot be sufficiently retained because the strength is insufficient due to being too thin, and exceeds 150 g / m ² . When it is applied to the face as a mask for a beautiful face pack, there is a problem that it becomes too heavy and easily peels off. Therefore, it is preferably set to 50 to 150 g / m ² .

As the non-woven fabric made of rayon, a basis weight of 30-120 g /
It is preferable to use a spunlace nonwoven m ^2. Basis weight of the rayon nonwoven fabric, in the case of less than 30 g / m ² is too thin stretched during molding, there is a problem that can not be held sufficiently absorbent, exceeds 120 g / m ^2, It is preferable to set the amount to 30 to 120 g / m ² because the cosmetic liquid is wasted and excessively heavy due to excessive water absorption.

Preferably, the material cloth is made of a nonwoven fabric having a total basis weight of 80 to 180 g / m ² , which is formed by overlapping a shape-retaining nonwoven fabric and a rayon nonwoven fabric and joining them by hydroentanglement from the rayon nonwoven fabric side. It is. When the total fabric weight of the material cloth is less than 80 g / m ² , there is a problem that the preferable strength and shape retention as a three-dimensional molding mask and the impregnation amount of the cosmetic liquid necessary as a facial mask cannot be balanced, it exceeds 180 g / m ^2, the unnecessarily heavy use as a facial mask, since a good feeling it is difficult to obtain, it is preferable to set the 80~180g / m ^2.

  The method for producing a mask for three-dimensionally molded facial pack according to the present invention produces a material cloth formed by integrating a non-woven fabric for shape retention that can be hot press-molded with a non-woven fabric made of rayon that has high water absorption and is comfortable to touch. The material cloth is hot press-molded into a mask shape covering the face with a rayon nonwoven fabric as the inner surface.

  In this manufacturing method, a nonwoven fabric for shape retention and a nonwoven fabric made of rayon are integrated to produce a material cloth, and this is heat-pressed to create irregularities on the face that require beauty such as the eyebrows, eye sockets, and around the nose. It is possible to easily manufacture the mask for the three-dimensionally shaped face pack that can be adhered closely without gaps and that is excellent in the feeling of use such as the touch.

  According to the face pack mask of the present invention, a spunlace nonwoven fabric mainly composed of rayon fibers having high water absorption and good touch is formed on the entire inner surface of the nonwoven fabric mask that is three-dimensionally molded to match the face shape, and the face. Because it is three-dimensionally shaped to follow the unevenness of the eye, it can provide a sufficient adhesion feeling while maintaining a soft touch even in areas requiring beauty care such as the eyebrows, eye sockets, around the nose, and the mouth Thus, it is possible to obtain a high cosmetic effect and a good feeling of use that cannot be obtained with a mask for a facial pack in which a conventional flat nonwoven fabric is punched.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1 and FIG. 2, the face pack mask 40 is obtained by hot pressing a material cloth 20 (see FIG. 4) into a three-dimensional shape along the uneven shape of the face. The punch hole 41 is provided with a punch hole 42 in the lip portion at the mouth, and a punch hole 43 corresponding to the eyelid portion is provided in the eye socket. Further, the outer periphery of the face pack mask 40 is formed with steps so that the portion 40a corresponding to the forehead is shallow, the portion 40b corresponding to the mouth from the cheek is slightly deeper, and the portion 40c corresponding to the neck from the chin is deepest. A notch 44 is provided in a portion corresponding to the boundary and the neck of the chin so that the lower part of the chin or the cheek is wrapped so as to follow the three-dimensional shape. However, the face pack mask 40 can be formed into an arbitrary three-dimensional shape as long as it is a three-dimensional shape along the face.

  As shown in FIG. 3, a shape-retaining nonwoven fabric layer 21 </ b> A mainly made of thermoplastic synthetic resin fibers containing binder fibers is provided on the outer surface side of the face pack mask 40, and the inner surface side (contact with the face) On the surface side), a non-woven fabric layer 22A made of rayon mainly composed of rayon fibers and having a soft touch is provided.

  As shown in FIGS. 3 and 4, the material cloth 20 of the face pack mask 40 is obtained by hydroentangling a web in which a low-melting binder fiber is mixed with fibers made of a thermoplastic synthetic resin such as polyethylene terephthalate. The shape-retaining nonwoven fabric 21 made of spunlace nonwoven fabric is laminated with a rayon nonwoven fabric 22 made of spunlace nonwoven fabric mainly composed of rayon fibers and subjected to hydroentanglement again from the side of the rayon nonwoven fabric 22 to give two sheets. The nonwoven fabrics 21 and 22 having different sizes are joined. The face pack mask 40 has a shape-retaining non-woven fabric layer 21A formed by a shape-retaining non-woven fabric 21 made mainly of plastic synthetic resin fibers, and a rayon on the inner surface by a rayon non-woven fabric 22 mainly composed of rayon fibers. The non-woven fabric for shape retention 21 and the non-woven fabric 22 made of rayon are arranged so that the non-woven fabric layer 22A is formed, and the material cloth 20 is manufactured by hot press molding into a three-dimensional mask shape along the face.

When the blending ratio of the binder fiber with respect to the shape-retaining nonwoven fabric 21 is less than 15%, there is a problem that the adhesive fixing between the fibers is not sufficient and the shape cannot be sufficiently retained. Since it becomes too large to allow flexibility in shape, it is preferably set to 15% to 60%, preferably 20 to 40%. Also, the basis weight of the shape retaining non-woven 21, in the case of less than 50 g / m ^2, there is a problem that can not be sufficiently retain its shape due to the lack strength too thin is more than 150 g / m ^2, facial pack When it is applied to the face as a mask for use, there is a problem that it becomes too heavy and easily peels off. Therefore, it is preferably set to 50 to 150 g / m ² , desirably 70 to 100 g / m ² .

  As the shape-retaining non-woven fabric 21, in addition to polyethylene terephthalate, fibers made from other thermoplastic synthetic resins such as polypropylene and polyacrylonitrile can be used, and about 10 to 30% of rayon, cotton, etc. can be used. What mix | blended natural fiber can also be used.

Basis weight of the rayon nonwoven fabric 22 in the case of less than 30 g / m ² is too thin stretched during molding, there is a problem that can not be held sufficiently absorbent, exceeds 120 g / m ² It is preferable to set the amount to 30 to 120 g / m ² because the cosmetic liquid becomes useless and becomes heavier than necessary because it has excessive water absorption. The material cloth 20 is set to a total basis weight of 80 to 180 g / m ² .

  Thus, since the shape-retaining nonwoven fabric 21 made of thermoplastic synthetic resin containing binder fibers is bonded to one surface of the material cloth 20, the material cloth 20 is formed into a three-dimensional shape by performing hot press molding. Can be granted. In addition, since the non-woven fabric 22 made mainly of rayon fibers, which is comfortable to the touch, is bonded to the other surface of the material fabric 20, the surface is hardened by the solidification of the binder fibers at the time of molding, unlike the nonwoven fabric 21 for shape retention. However, sufficient water absorption and flexibility as a mask for a beautiful face pack, and good usability can be imparted.

Next, the manufacturing method of the mask 40 for three-dimensional shaping | molding face packs is demonstrated.
FIG. 2 is a schematic view when the three-dimensionally shaped facial pack mask 40 is molded by a match mold.

  First, the material cloth 20 has a soft and soft spunlace nonwoven fabric 22 mainly composed of rayon fibers on the inner surface of the mask, and a spunlace nonwoven fabric 21 mainly made of thermoplastic synthetic resin fibers containing binder fibers on the outer surface of the mask. In this way, it is supplied to the manufacturing apparatus, preheated from above and below by heating means such as a ceramic heater, and supplied to the mold 30. The material cloth 20 is clamped by the male mold 30a and the female mold 30b of the match mold mold 30 and molded into a mask shape.

  Next, as shown in FIG. 1, the outer periphery and the cut 44, the nasal cavity portion punch hole 41, the lip portion punch hole 42, and the punch hole 43 corresponding to the eyelid portion are punched into the mask-shaped sheet. Trimming is performed to obtain a face pack mask 40.
