Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin cleanser for removing dirt and aging stratum corneum of the skin to make the skin beautiful.

[0002]

2. Description of the Related Art Raw silk is generally manufactured through the steps of dry cocoon → selection cocoon → boiled cocoon → spun silk → rewinding → finishing. Of these, the boiled cocoon process is performed as a pretreatment of the reeling process. The cocoon thread constituting the cocoon layer is composed of two kinds of proteins, fibroin and sericin, and as shown in FIG. 7, the sericin layer 2 surrounds two fibroin fibers 1 having a substantially triangular cross section.
The structure is surrounded by. In the cocoon state, the cocoon threads are stuck to each other due to the sticking action of sericin. Therefore, the cocoons are treated with boiling water to soften the sericin appropriately to weaken the sticking force, or to melt a part thereof to facilitate the reeling. In the next reeling step, raw silk is taken out from the boiled cocoon, but in this case, the short cocoon thread on the surface of the cocoon is removed in order to find the mouth of one long cocoon thread (length of about 1000 to 1400 m). .

A raw string-shaped piece (kibiso) is formed by collecting and drying these short cocoon threads. There are various types of rawhide, such as Zakurei rawhide (abbreviated as "Zaki") made of Zakurei silk, and instrument raw leather made of instrumental silk (abbreviated as "Kiki"). It is used as a raw material for silk spinning, along with yarn milling scraps (Noshi, Hizu, fried cocoons, etc.) and sericulture scraps (eg shell cocoons, waste cocoons, etc.)

[0004] On the other hand, in the case of a skin cleaning tool used for putting or massaging the skin to remove dirt and aging stratum corneum to make the skin beautiful, conventionally, a part or all of the cleaning action surface is formed of silk cloth. There is something. Silk cloth is used for the cleaning surface because silk cloth is kind to the skin, has better hygroscopicity than chemical fibers, and dries faster than cotton.It also has characteristics suitable for this application, as well as glycine and alanine that make up fibroin. The reason is that tyrosine and other amino acids are believed to be exuded to the outside when used to make the skin beautiful.

[0005]

However, since there are many inefficient aspects of the silk spinning process using rawhide, etc. as a raw material, the silk spinning product is inevitably high in price. However, the demand is declining in recent years because the quality is not good.

[0006] On the other hand, the skin cleaning tool using the silk cloth for the cleaning action has a problem that the manufacturing cost cannot be reduced because the silk cloth is expensive. In addition, the texture and feel of the silk cloth are two-dimensional when woven flatly, and since the silk cloth is composed of relatively thick silk threads, the effect of removing skin dirt and aging stratum corneum is sufficient. I couldn't say that.

The present invention has been made in view of the above problems, and effectively utilizes the rawhide ram, which is a by-product of raw silk production, to achieve low manufacturing cost, good texture and feel, and smooth skin. It is an object of the present invention to provide a skin cleaning tool that is also excellent in the cleaning effect.

[0008]

Means for Solving the Problems In order to achieve the above-mentioned object, the skin cleaning tool according to the present invention collects short cocoon threads removed from a cocoon boiled in cocooning the raw silk, and dries the raw rams. Formed and refined this rawhide to make a refined rawhide, and using this refined rawhide to form at least a part of the cleaning action surface.

[0009]

[Operation] When the short cocoon threads removed from the boiled cocoons are collected and dried, the cocoon threads stick to each other due to the sticking action of the softly boiled sericin to form a hard cord-like raw ram.
When this is refined with a liquid such as soap, alkali or proteolytic enzyme, sericin is dissolved and the gluing state of the cocoon threads is released, and the fibroin fibers are unwrapped by the sericin layer and one cocoon thread becomes two. The fibroin fiber is divided into a large number of fibroin fibers in a bundle to form a refined rawhide. If this refined raw leather is used for the cleaning action surface of the skin cleaning tool, each of the fibroin fibers comes into contact with the skin at the time of use, and the texture and feel are good.
The extremely fine fibroin fiber having a substantially triangular cross section also improves the dirtiness of the skin and the removal of the aged stratum corneum.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 6 is a schematic perspective view showing an enlarged part of the refined rawhide. As shown in the figure, the refined rawhide 3 is a bundle of a large number of extremely thin fibroin fibers 1. Each fibroin fiber 1 has a substantially triangular cross-sectional shape as shown in FIG. 7, and its thickness is 18
.About.36 .mu.m, and the fineness is about 1.5 to 3.5 denier, which is extremely thin. Moreover, although the fibroin fibers 1 are slightly entangled with each other, they are not particularly twisted together.

In order to obtain this refined raw ramie, first, when the raw silk is rolled, short cocoon filaments removed from the boiled cocoon are sought in order to find the mouth of the long cocoon filaments and dried. As a result, the cocoon threads stick to each other due to the sticking action of the softly boiled sericin to form a brown-colored, hard cord-like rawhide ram (not shown). Generally, the diameter of raw hide-bush is about 0.5 cm and the length is about 60 to 100 cm.

Next, this raw hide-brush is refined. Refining is done by boiling raw hide-bush with an aqueous solution of soap. It can also be refined using an aqueous solution of alkali (such as caustic soda) or proteolytic enzyme. As a result, sericin is dissolved and the gluing state between the cocoon threads is released, and the surrounding of the fibroin fiber 1 by the sericin layer 2 is released, and one cocoon thread is divided into two fibroin fibers 1 and is shown in FIG. It becomes a state.

Then, a plurality of the refined raw hide rams 3 thus formed are joined by a joining machine for a long time. In addition,
The refined raw leather ramie 3 may be tied and joined together, but it is preferable to use a joining machine that does not allow knots, and the work is efficient. Further, the refined raw leather 3 does not necessarily have to be connected, but it is convenient that the refined raw leather 3 is connected for a long time in the subsequent process.

Then, using a sewing machine for flocking, as shown in FIG. 2, the refined rawhide 3 is driven from the back side of the fabric 4 to form a loop of the refined rawhide 3 on the front side of the fabric 4. In addition,
The structure of the cloth 4 is arbitrary, and may be, for example, woven cloth made of cotton or chemical fiber, or non-woven cloth. It is also conceivable to apply an adhesive to the back side of the cloth 4 to prevent the refined rawhide 3 from coming off.

As shown in FIG. 1, the thus-fabric cloth 4 is sewn into a bag having a loop forming surface on the front side and a porous elastic body 5 such as a sponge placed inside to form a skin cleaning tool 6. Form. In this skin cleaning tool 6, the entire loop forming surface on the surface is the cleaning action surface 7.

The skin cleanser 6 can be used for washing the face and body with soap or face wash, or for putting or massaging the face or the like in a dry state or a state moistened with water. For example, as described above, since each of the extremely thin fibroin fibers 1 comes into contact with the skin, the texture and the feel are good, and the dirt on the skin and the aging stratum corneum can be removed well. It is considered that this is because the fibroin fibers 1 are extremely thin and reach deep inside the fine irregularities on the surface of the skin, and due to their thinness and triangular shape, they are apt to be caught in the dirt and aging stratum corneum of the skin. In addition, in the present embodiment, due to the appropriate elasticity of the loop of the refined rawhide ramie 3, the feeling of use and the shape effect are further enhanced.

Further, since the refined rawhide 3 can be produced without as many steps as silk cloth, glycine,
The loss rate of alanine, tyrosine and other amino acids is low, and since many fibroin fibers 1 are gathered in a state where they have gaps between them, the useful components are more easily exuded to the outside than silk cloth, and silk cloth As described above, various kinds of additives are not added in the manufacturing process, and for these reasons, it is considered that the effect of making the skin beautiful is excellent.

In the above-described embodiment, the entire surface of the skin cleaning tool 6 is the cleaning action surface 7 using the refined rawhide 3 but, for example, only one side is the cleaning action surface 7 using the refined rawhide 3. It is also conceivable to form a cleaning action surface using a loofah fiber or the like on the other side, which has a different action. Further, the other side is a holding surface for holding the skin cleaning tool 6 in the hand,
It is also possible to sew an annular belt or the like here. Further, although the refined rawhide 3 was used without bleaching in the above-mentioned examples, it may be bleached with a chemical such as hydrogen peroxide or hydrosalophite, and it may be dyed in any color.

FIG. 3 shows another embodiment. The skin cleaning tool 6 according to the present embodiment is the same as the above-described embodiment, in which the cloth 4 having the loop of the refined rawhide 3 is sewn into a U-shaped bag having an opening 8 at one end in a plan view. is there. This skin cleaning tool 6 is used by inserting a finger through the opening 8 and is particularly suitable for putting on the face.

4 and 5 show another embodiment. The skin cleaning tool 6 according to the present embodiment is one in which the periphery of the porous elastic body 5 is covered with a coarse knitted cloth 9 formed by knitting the refined raw leather ramie 3. In this embodiment, the amount of refined rawhide 3 used can be made smaller than that in the above-mentioned embodiment, and the manufacturing cost can be reduced. Needless to say, the skin cleaning tool according to the present invention is not limited to the above embodiments.

[0021]

As described above, in the skin cleaning device according to the present invention, since the cleaning action surface is formed by using the refined rawhide, which can be easily produced from the rawhide, which is a by-product of raw silk production, the rawhide is used. Can be effectively used and the manufacturing cost of the skin cleaning tool can be reduced. In addition, when used, each of the many fibroin fibers that make up the refined raw terracotta comes into contact with the skin, so the texture and feel are good, and the extremely thin fibroin fibers with a substantially triangular cross-section make the skin dirty and aged keratin. The layers can be dropped well.
