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 for applying cosmetics or finishing after application. In the present specification, "silk fiber" is a general term for fibers made of silk, "raw silk" is silk fiber obtained by unwinding silkworm cocoons, and "kneaded silk" is made by refining raw silk. The obtained silk fiber is used.

[0002]

2. Description of the Related Art Conventionally, cosmetic puffs have been used in which a pile is formed by electrostatically implanting nylon fibers on a sponge body made of NBR or the like.

On the other hand, it has been strongly attempted to electrostatically implant silk fibers in cosmetic puffs due to various demands such as high-grade feeling of silk fibers and being a natural product.

[0004]

However, at present, a silk fiber flocking puff that can be used as a makeup puff has not been completed.

The reason for this is that when silk fibers are cut and planted to a size of several mm, which is generally used for cosmetics, the thickness of the silk fibers is
This is because the fibers themselves were hard due to the strength of the waist or the cross-sectional shape, and the flocked pile surface had a rough feel to the skin. Usually, nylon puffs for cosmetic puffs with a thickness of 1.1 to 2.8 decitex are used, but raw silk has a thickness of about 3.3 decitex and a modified cross section. The sericin covering the surface of raw silk gives a rough and rigid feeling when using its cross section.

Further, flocking using silk fibers is extremely difficult, and those flocking silk fibers are hardly found not only in cosmetic puffs but also in other products.

The reason is that raw silk is apparently one silk fiber consisting of two short fibers glued with sericin, so-called fibroin, so that when cut, the fibroin appearing in the cross-section branches off. If the branched fibroin is bent or entangled, the polarity cannot be taken during static hair transplantation, so stable static hair transplantation cannot be performed.

[0008] Therefore, as a result of intensive studies, the present inventor, as a puff for makeup, gives a user a soft feeling peculiar to natural silk fiber, and a silk fiber flocking puff that can be sufficiently satisfied in terms of makeup effect. Invented

[0009]

A silk fiber flocking puff according to the present invention is obtained by electrostatically flocking silk fibers containing 50% or more of 0.5 decitex to 1.7 decitex silk fibers. As the silk fiber of 0.5 decitex to 1.7 decitex, kneaded silk obtained by refining raw silk having an average of about 3.3 decitex can be used. Further, it contains 50% or more of 0.5 decitex to 1.7 decitex kneaded silk obtained by refining raw silk having an average of 3.3 decitex, and a fiber length of 5 mm to 3 mm.
It is desirable to use silk fibers cut to a specified length of 0% or more.

With the above-mentioned structure, since the fine silk fibers having a thickness of 50% or less than usual becomes 50% or more, the soft feeling of the whole flocked pile surface is increased. Further, when silk fibers of 0.5 decitex to 1.7 decitex are obtained by refining, a considerable amount of sericin is removed, and thus 50% or more of the obtained silk fibers are separated for each fibroin. This is considered to be the reason, and this causes flexibility, so that the soft feeling of the flocked pile surface is further increased. Furthermore, since 50% or more of the silk fiber cut to a specified length of 50% or more in the fiber length range of 0.5 mm to 3 mm exists as fibroin, originally,
Can prevent branching that occurred in the state of raw silk,
In addition, even if it branches, the bent or entangled portions are minute, so that static hair transplantation is not hindered.

Further, the construction as a silk fiber flocking puff can be applied to a conventional cosmetic puff having a pile surface flocked with nylon fibers, except that it has a pile surface flocked with silk fibers. The silk fiber flocking puff is a puff composed of a sponge body, and the silk fiber flocking puff electrostatically flocked on at least one surface of the sponge body, and the silk fiber flocking puff is formed by wrapping the sponge body in a thin film sheet. A puff that can be considered is a silk fiber flocking puff in which static electricity is flocked to the thin film sheet, or a silk fiber flocking puff in which the thin film sheet in which a silk fiber flocking puff is statically flocked is attached to a sponge body.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings.

[Production of Silk Fiber] First, cocoons are boiled with steam or hot water to dissolve the surface of sericin so that raw silk can be easily loosened. Next, in a state where it is floated in warm water, the thread end of the raw silk is pulled out, unwound and reeled. The thickness of the raw silk at this time is about 3.3 decitex. The unwound silk is soaked in hot water or soapy water to remove sericin, and kneaded silk is produced. This process is refining. The time to soak is
Depending on the state of the cocoons and raw silk, soak in about 50% of sericin. The kneaded silk at this time contains 50% or more of silk fibers having a thickness of 0.5 decitex to 1.7 decitex. This kneaded silk with a crusher etc.
Cut short to a specified fiber length of 50% or more in the range of 3 mm. The extremely thin and short silk fibers A thus obtained are used to perform static flocking as exemplified below.

[First Embodiment] FIG. 1 shows a first embodiment. FIG. 1A is a perspective view of a cosmetic puff, and FIG.
Is a sectional view thereof.

In FIG. 1, 10 is a makeup puff,
The above-mentioned silk fiber A is electrostatically flocked on one surface and the peripheral surface of the rectangular sponge body 11 as a base material.

As the sponge body 11, a latex sponge such as acrylonitrile-butadiene rubber (NBR) or natural rubber (NR), or a sponge body generally used for cosmetic puffs such as polyurethane foam is used.

Further, the shape of the sponge body is not limited to a rectangle, but the shape of a makeup puff having a flocked pile formed on the surface of this kind, for example, a circle, an ellipse, an oval shape,
It may be formed into various commonly used shapes such as a sphere.

With the above-mentioned structure, the silk fibers A to be flocked have a fineness of 50% or less than normal, and 50% or more of the fine fibers, so that the softness of the entire flocked pile surface is increased. However, the texture of the original silk fiber, which is peculiar to the cross section, is eliminated, and the user is given a sufficient satisfaction and makeup effect during makeup. Moreover, since silk fibers of 0.5 decitex to 1.7 decitex are obtained by refining, a considerable amount of sericin is removed, and thus the obtained silk fibers are 50%.
It is considered that the above is separated for each fibroin, and since it has flexibility due to this, the soft feeling of the flocked pile surface is further increased, and the soft feeling is completely different from that of nylon fiber flocked. It is possible to obtain a cosmetic puff with a high commercial value in combination with the use of silk fiber because of its excellent quality. Fiber length 0.5 mm
Since it cuts to a specified length of 50% or more within a range of up to 3 mm, fibrin accounts for 50% or more of the length, which prevents branching that originally occurred in the raw silk state. Even if a branch is formed, the bent or entangled parts are minute, so electrostatic hair transplantation can be performed easily without disturbing electrostatic hair transplantation.

[Second Embodiment] FIG. 2 is a second embodiment, and is a partially cutaway perspective view of a makeup puff. This embodiment is a modification of the cosmetic puff 10 in the first embodiment.

The makeup puff 20 is formed by forming a thin film sheet 22 on the surface of a base cloth 21 in which the above-mentioned silk fibers A are electrostatically flocked into a circular bag shape, and enclosing a circular sponge body 23 therein. It is a thing. As the base cloth 21, a base cloth made of synthetic resin, natural rubber or the like, which is usually used for the cosmetic puff of this form, is used. Further, the sponge body 23 enclosed inside is made of acrylonitrile-butadiene rubber (NB
R), a latex sponge such as natural rubber (NR), or a sponge body such as polyurethane foam generally used for cosmetic puffs is used. In addition, makeup puff 2
0 is not limited to the above-mentioned shape, and may be formed into various shapes generally used for a cosmetic puff in which a sponge body is enclosed in a bag of this type. Also, the thin film sheet 22
As a method of forming a bag from the above, two thin film sheets having the same size may be stacked and the peripheries thereof may be sewn together, bonded by a thermocompression bonding welder, or high frequency bonding or ultrasonic bonding may be used.

With the above-described structure, the silk fibers A to be flocked have a fineness of 50% or less than normal and 50% or more of fine fibers, so that the softness of the entire flocked pile surface is increased. However, the texture of the original silk fiber, which is peculiar to the cross section, is eliminated, and the user is given a sufficient satisfaction and makeup effect during makeup. Moreover, since silk fibers of 0.5 decitex to 1.7 decitex are obtained by refining, a considerable amount of sericin is removed, and thus the obtained silk fibers are 50%.
It is considered that the above is separated for each fibroin, and since it has flexibility due to this, the soft feeling of the flocked pile surface is further increased, and the soft feeling is completely different from that of nylon fiber flocked. It is possible to obtain a cosmetic puff with a high commercial value in combination with the use of silk fiber because of its excellent quality. Fiber length 0.5 mm
Since it cuts to a specified length of 50% or more within a range of up to 3 mm, fibrin accounts for 50% or more of the length, which prevents branching that originally occurred in the raw silk state. Even if a branch is formed, the bent or entangled parts are minute, so electrostatic hair transplantation can be performed easily without disturbing electrostatic hair transplantation.

[Third Embodiment] FIG. 3 is a partially cutaway perspective view of a makeup puff according to a third embodiment. This embodiment is a modification of the cosmetic puff 10 in the first embodiment.

The makeup puff 30 is constructed by attaching a thin film sheet 32 in which silk fibers A are electrostatically flocked onto the surface of a rectangular base cloth 31 to the surface of a rectangular sponge body 33. As the base cloth 31, a base cloth made of synthetic resin, natural rubber or the like, which is usually used for the cosmetic puff of this form, is used. As the sponge body 33, a latex sponge such as acrylonitrile-butadiene rubber (NBR) or natural rubber (NR), or a sponge body generally used for cosmetic puffs such as polyurethane foam is used. Further, the shapes of the base cloth 31 and the sponge body 33 are not limited to the rectangular shape, and the shape of the makeup puff to which the thin film sheet in which the piles of this kind are transplanted is attached, for example, a circular shape, an elliptical shape, an oval shape, a spherical shape, etc. It may be formed into various commonly used shapes.

With the above-mentioned structure, the silk fibers A to be flocked have a thinness of 50% or less than normal, and 50% or more of fine fibers, so that the softness of the entire flocked pile surface is increased. However, the original texture of the silk fiber, which is peculiar to the cross-section, is eliminated, and a sufficient satisfaction and makeup effect for the user's makeup are provided. Moreover, since silk fibers of 0.5 decitex to 1.7 decitex are obtained by refining, a considerable amount of sericin is removed, and thus the obtained silk fibers are 50%.
It is considered that the above is separated for each fibroin, and since it has flexibility due to this, the soft feeling of the flocked pile surface is further increased, and the soft feeling is completely different from that of nylon fiber flocked. It is possible to obtain a cosmetic puff with a high commercial value in combination with the use of silk fiber because of its excellent quality. Fiber length 0.5 mm
Since it cuts to a specified length of 50% or more within a range of up to 3 mm, fibrin accounts for 50% or more of the length, which prevents branching that originally occurred in the raw silk state. Even if a branch is formed, the bent or entangled parts are minute, so electrostatic hair transplantation can be performed easily without disturbing electrostatic hair transplantation.

As in each of the embodiments described above, the construction as a silk fiber flocking puff has a conventional makeup puff having a nylon fiber flocked pile surface, except that it has a silk fiber flocked pile surface. It is possible to provide a cosmetic puff having a flocked pile surface of silk fiber, which has been eagerly desired in the past, in place of the flocked pile surface of nylon fiber.

The present invention is not limited to the above embodiments, but includes a wide variety of modifications without departing from the spirit of the present invention.

[0027]

The silk fiber flocking puff according to the present invention is 0.5
A silk fiber containing 50% or more of silk fiber of decitex to 1.7 decitex is electrostatically flocked. As the silk fiber of 0.5 decitex to 1.7 decitex, kneaded silk obtained by refining raw silk having an average of about 3.3 decitex can be used. The average is about 3.
Includes 50% or more of 0.5 decitex to 1.7 decitex kneaded silk obtained by refining 3 decitex raw silk, and cut it to a specified length of 50% or more in a fiber length of 0.5 mm to 3 mm. It is desirable to use silk fibers.

With the above construction, the thin silk fibers having a thickness of 50% or less than usual will be 50% or more, so that the soft feeling of the whole flocked pile surface is increased and the rough feeling at the time of makeup is provided. It is eliminated and gives the user sufficient satisfaction and cosmetic effect. Also 0.5 decitex
When 1.7 decitex silk fibers were obtained by refining, a considerable amount of sericin was removed, and it is considered that 50% or more of the obtained silk fibers are separated for each fibroin. Since it has flexibility, the softness of the flocked pile surface is further increased, and the quality that is completely the same as the softness of nylon fiber flocking is obtained, and silk fibers are used. Together with this, we can provide cosmetic puffs with high commercial value. Furthermore, since 50% or more of the silk fibers cut to a specified length of 50% or more in the fiber length range of 0.5 mm to 3 mm exist as fibroin, the branching that originally occurred in the raw silk state was generated. It can be prevented, and since the bent or entangled portions are minute even if branched, electrostatic flocking is not hindered, and there is an advantage that productivity is improved.

The composition as a silk fiber flocking puff can be applied to a cosmetic puff having a conventional nylon fiber flocked pile surface, except that it has a silk fiber flocked pile surface. The silk fiber flocking puff is a puff composed of a sponge body, and the silk fiber flocking puff electrostatically flocked on at least one surface of the sponge body, and the silk fiber flocking puff is formed by wrapping the sponge body in a thin film sheet. A puff that can be considered is a silk fiber flocking puff in which electrostatically flocking is applied to the thin film sheet, or a silk fiber flocking puff in which a thin film sheet in which a silk fiber flocking puff is electrostatically flocked is adhered to a sponge body is used. It is possible to provide a cosmetic puff having a flocked pile surface of silk fiber, which has been eagerly desired in place of the pile surface.
