Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a body cleaning tool useful for polishing the skin without using soap.

[0002]

2. Description of the Related Art As a body cleaning tool of this kind, for example,
It is known to polish the skin after washing the face, in which the surface of a core body made of polyurethane foam is covered with an epidermis made of silk which is soft to the touch.

[0003]

However, the above-mentioned body cleaning tool covered with a silk-made epidermis composed of fibers obtained by wrapping a protein fiber called fibroin with a colloid component called sericin is gentle to the skin, Since the surface of the epidermis is smooth and easily slips against the skin, it is necessary to rub the skin a number of times in order to sufficiently remove dirt, unnecessary keratin and sebum, and the cleaning efficiency is low.

An object of the present invention is to provide a method of manufacturing a body cleaning tool which can improve the cleaning efficiency while ensuring the gentleness to the skin.

[0005]

DISCLOSURE OF THE INVENTION The present invention provides a body cleaning tool having a core of polyurethane foam integrally covered with a textured silk skin on the surface of the core .
When making, soft polyurethane that is the material of the core
While melting and heating one side of the foam
And the polyurethane material
Between the laminating rollers and silk that is thinner than the thickness
Through the above-mentioned polyurethane foam on the heating and melting surface side
Laminated silk and before this laminated
The silk and the polyurethane foam are
The foam is uncured and its non-heated side is
Tension roller so that it touches the circumferential surface of the tension roller.
The guide drum while applying tension to the
Then, it is wound up as a composite base material on the take-up roller,
It is characterized in that the material is cut into a required shape to be finished into a body cleaning tool .

[0006]

According to the body cleaning tool obtained by the above-mentioned manufacturing method , since the core has elasticity and the epidermis is silk, it is gentle on the skin, and the epidermis is wrinkled to form irregularities on the surface of the epidermis. Therefore, just rubbing this lightly on the skin will cleanse unnecessary skin cells and skin oils and remove them efficiently.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a body cleaning tool according to the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the body cleaning tool is formed by integrally covering a surface of a core body 1 made of polyurethane foam having a required shape with a skin 2 made of silk with a grain 3. The shape of the body cleaning tool should be spherical, disk-shaped, square, or other three-dimensional shape, or band-shaped flat plate that can also be used for body towels for lapping, or glove-shaped so that it fits easily in your hand. It can also be formed. As the silk which is the material of the skin 2, a woven fabric or a non-woven fabric made of 100% natural silk is used. Silk non-woven fabric is preferable because it can reduce the material cost. As the non-woven fabric made of 100% natural silk, for example, a non-woven fabric manufactured by water jet processing without using an adhesive is used.

A body cleaning tool having the above structure is shown in FIG.
As shown in FIG. 3, the silk non-woven fabric 5 which is the material of the skin 2 is laminated on one or both sides of the polyurethane foam 4 which is the material of the core body 1 to form the silk non-woven fabric 5
To produce a composite base material 6 having a spherical shape,
Cut into a required shape such as a disc or a square to make a body cleaning tool. When the composite base material 6 in which the silk nonwoven fabric 5 is laminated on one surface of the polyurethane foam 4 is used, after cutting the composite base material 6 into a required shape,
As described above, the surfaces 4a, 4a of the polyurethane foam 4 on the side on which the silk nonwoven fabric 5 is not laminated can be bonded to each other.

The composite base material 6 is manufactured, for example, as follows. As shown in FIG. 4, while one side of a rolled soft polyurethane foam 4 (for example, 14 mm thick) is heated and melted by a burner B or the like, the polyurethane foam 4 and a rolled silk nonwoven fabric 5 (for example, 0 mm Laminate roller 7,7 with a thin material of 1 mm or less)
The non-woven silk fabric 5 is laminated on the heating and melting surface side of the polyurethane foam 4 through the space, and further, under the uncured state of the polyurethane foam 4, the polyurethane foam 4 is passed through a tension roller 8 of small diameter and wound through a guide drum 9 while applying tension The composite base material 6 is wound around the roller 10. At this time, the non-heated surface side of the polyurethane foam 4 contacts the circumferential surface of the tension roller 8, and the silk non-woven fabric 5 is passed so as to overlap the heated surface side of the polyurethane foam 4. At this time, even if the silk non-woven fabric 5 is stretched over the tension roller 8. Although it is harder to stretch than the polyurethane foam 4, the heating surface side of the polyurethane foam 4 tends to stretch on the tension roller 8 and returns to its original shape as it passes through the tension roller 8. The shrinkage is added to the silk non-woven fabric 5 and the grain 3 is generated. With the silk non-woven fabric 5 in which the grain 3 is generated, the uneven skin 2 can be obtained.

Silk non-woven fabric 5 is replaced with polyurethane foam 4
In the case of laminating on both sides of the above, once the silk non-woven fabric 5 is wound on one side of the polyurethane foam 4 through the laminating rollers 7, 7 and the tension roller 8 in the above-described manner, and then on another line. The composite base material 6 and the same silk non-woven fabric 5 as the non-woven silk fabric 5 are provided between the laminating rollers 7, 7 and the tension roller 8
By passing it through, the silk non-woven fabric 5 can be similarly laminated on the other surface of the polyurethane foam 4 on the side not having the silk non-woven fabric 5.

According to the body cleaning tool obtained by the manufacturing method of the present invention, there is an advantage that the cleaning efficiency can be enhanced while the gentleness to the skin can be secured.
