Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to various kinds of silk materials, in particular,
The present invention relates to a method for treating a silk material that enables effective use of the silk material that has been conventionally discarded.

[0002]

2. Description of the Related Art Silk has been used as raw silk for silk fabrics since ancient times. It is light, warm and comfortable to the skin, does not interfere with human skin breathing, helps control temperature and humidity, and has excellent moisturizing effects, allergies and skin disorders. It has been used as a clothing material that does not cause This silk sub-silk thread (selected cocoons, scraps from the spinning process, scraps from the weaving process), cocoons after the pupae (Cutted Co)
Most of the silk materials such as a cocoon called a coon after removing a live pupa that has been cut out and a cocoon that is simply a cocoon after removing a pupa from the cocoon have been discarded.

[0003]

[Problems to be Solved by the Invention] At present, various uses are being developed for the effective use of silk materials, but they are still insufficient.

The present invention is intended to utilize a silk material as a coating material for human skin and a filtering agent. Conventionally, as such a coating material for the outer skin of the human body, for example, eyebrows, which have been used as cosmetics, are currently used as a raw material by collecting soot generated by incomplete combustion of petroleum-based materials. There are various black products manufactured using soot as a raw material (for example, hair dye, mascara, eye shadow, eye line, cosmetics, etc.). But these are
Since petroleum-based materials are produced by incomplete combustion, the carcinogenic substance renspirene may be generated and mixed in during the process of incomplete combustion, and its use is already prohibited in the United States.

Conventionally, coconut husk activated carbon and the like are well known as a filtering agent. The raw material of the conventional carbonized filtering agent is mainly a plant, and the carbonized one is
It was found that the adsorption action was inferior to that of silk, which is an animal raw material.

An object of the present invention is to provide a method for treating a silk material, which can inexpensively obtain a coating material for a human body skin which does not harm the human body and a filtering agent which is excellent in the action of adsorbing and removing impurities and unnecessary substances. It is in.

[0007]

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a sub-silk thread produced from wild silkworm, sericulture, etc. (selective cocoons, scraps from the spinning process, scraps from the weaving process),
Cocoon after the pupa is pulled out (Cutted Cocoo
(The cocoon after removing the live pupae, which is called n), or simply the cocoon after removing the pupae from the cocoon, or as a processed product of wild silkworms and sericulture, cotton, silk noil, wrap, A sliver, or a silk material (100% of silk) such as a cut piece of silk woven fabric or silk knit, is carbonized at 600 ° C. to 2000 ° C. in an inert atmosphere, and then made into ultrafine particles with a particle diameter of 3 to 90 μm. It is intended to provide a method for treating a silk material, which is used as a coating material for a human outer skin such as an outer skin drug, an outer skin quasi drug, and a cosmetic.

Further, the present invention is a cocoon (Cutted) after removing pupae, such as sub-silk yarns generated from wild silkworms and sericulture (selected cocoons, scraps from the spinning process, scraps from the weaving process).
Cocoon called cocoon after removing the live pupa that has been cut), or simply a cocoon that has been removed from the cocoon, or pure cotton, silk noil, wrap, which is a processed product of wild silkworm and sericulture. Silk materials such as sliver or cutting waste of silk fabric or silk knit (silk 100
%) Is carbonized at 600 ° C. to 2000 ° C. in an inert atmosphere and then granulated or used as it is as a filtering agent.

[0009]

In the present invention, since carbonized powder of silk material (100% silk) is used as a coating material for human skin,
It can provide raw materials that are light and harmless to the human body. In this case, the silk material to be used is wild silkworm, sub-silk thread produced from sericulture, etc. (selection cocoon, scraps from the spinning process, scraps from the weaving process),
Cocoon after the pupa is pulled out (Cutted Cocoo
(The cocoon after removing the live pupae, which is called n), or simply the cocoon after removing the pupae from the cocoon, or as a processed product of wild silkworms and sericulture, cotton, silk noil, wrap, The raw material is relatively inexpensive because it is a sliver or cutting waste such as silk fabric or silk knit. In addition, when carbonizing the above-mentioned silk material, since it was treated under the condition of 600 ° C to 2000 ° C in an inert atmosphere, the original characteristics of silk are not killed, the goodness of silk is light, it does not interfere with human skin breathing, and the temperature It is possible to obtain a coating material for the outer skin of a human body, which has an ability to control humidity, has an excellent moisturizing effect, and has a performance that does not cause allergies and skin disorders. In this case, at 600 ° C. or lower, the carcinogenic substance renspirene may be generated.
This is because the silk fat contained in the silk material may become tar-like and cannot be made into fine particles in a later step, which is to be avoided. Further, carbonization at 2000 ° C. or higher is expensive in terms of manufacturing cost and does not make sense for industrial use.

In addition, in the case of forming ultrafine particles, fine particles smaller than 3 μm are expensive in terms of manufacturing cost, and fine particles smaller than this are not required in the case of practical use in the industry. Also, if it is larger than 90 μm, depending on the object to be used, the particles may be large, and even if they become gel-like or liquid, they may not fit on the skin more than expected when applied to the human body, or the skin may feel uncomfortable. This is because you may feel it.

When it is used as a filtering agent, it is also 60
When the temperature is 0 ° C. or lower, generation of carcinogenic substance renspirene is unavoidable, and when tar becomes silky fat, the filtration effect is remarkably reduced. Therefore, the temperature must be 600 ° C. or higher. In terms of granularity, the condition used when water quality is maintained in nature does not pose a problem even if the particle size is 10 mm or more, and the filtration during cleaning is about 5 mm, and the granular size does not matter. Moreover, silk is
It is the substance with the most adsorption energy in the natural world, and even if carbonized, this energy does not change,
With this adsorption energy, impurities and unnecessary substances can be filtered or purified.

EXAMPLES As shown in FIG. 1, the present invention shows, as shown in FIG. 1, sub-silk yarns and the like generated from wild silkworms and sericulture (selected cocoons, scraps from the silk-making process, scraps from the weaving process), and cocoons after the pupae are removed ( C
Utted Cocoon (a cocoon after removing the live pupa that has been cut out) or simply a cocoon that has been removed from the cocoon, or a cotton, silk noil, or wrap as a processed product of wild silkworms or sericulture. , Sliver, or a silk material (100% of silk) such as cutting waste of silk woven fabric or silk knitted fabric in an inert atmosphere at 600 ° C to 200 ° C.
After carbonization at 0 ° C., it is made into ultrafine particles with a particle size of 3 to 90 μm and used as a coating material for human skins such as outer skin medicine, outer skin quasi-drugs, cosmetics, or the above silk material is carbonized. After that, it is granulated or used as a filter as it is.

The silk material used in the present invention may be silk woven fabric or silk knitted fabric as it is, but these are very expensive in common sense, and it is not necessary to carbonize them.
It's too crazy. Currently, various uses of silk are being developed, but from a global perspective, silk raw materials are produced outside of China, but effective utilization is not progressing at present, and cocoons The fact is that some cocoons are used as food and then thrown away just like litter. If we carbonize these, it will be very useful in the world, and we will recognize that the effective use of resources and the provision of products that are harmless to the human body than conventional ones. Is used.

First, when carbonizing a silk material, it is not necessary to pretreat the silk material. The silk material is placed in a processing container of a sintering furnace or a firing furnace that can make the inside an inert atmosphere, and the temperature is 600 ° C. to 200 ° C. in an inert atmosphere.
Sintering or firing at 0 ° C to carbonize.

In the above treatment, it is absolutely necessary to completely carbonize at a temperature of 600 ° C. or higher. Hello 6
If the temperature is not higher than 00 ° C, the carcinogenic substance renspirene may be generated, and further, the silk fat in the silk material may cause tar-like formation, which does not form fine particles or particles.
It cannot fully utilize the adsorption energy of the original silk,
Even if you use any of them, the effect will be very weak, and it will be a product with no utility value. Further, at 2000 ° C. or higher, it requires a considerable amount of heat energy in terms of cost, which makes it expensive and difficult to industrially use.

When the carbonized material obtained by the above treatment is used as a coating material for human outer skin, it is treated with a crusher. In this case, in order to facilitate application to the human body, the particles are made into ultrafine particles having a particle diameter of 3 to 90 μm. In order to make ultrafine particles in this way, it is possible to use a crusher that utilizes fluid energy, and granulating is very easy. If so, it does not become tar-like and can be immediately made into granules.

In the above-mentioned pulverization treatment, fine particles smaller than 3 μm are expensive in terms of manufacturing cost, and fine particles smaller than this are not necessary in practical industrial use. Also,
If it is larger than 90 μm, depending on the object to be used, the particles may be large, and even if they become gel-like or liquid, they may not fit on the skin more than expected or the skin feels uncomfortable when applied to the human body. There is.

On the other hand, even when the above-mentioned carbonized product is used as a filtering agent, it is necessary to avoid generation of lenspirene, which is a carcinogenic substance, at 600 ° C. or lower,
If it becomes tar-like with silk fat, the filtration effect will be remarkably reduced. Therefore, it is always necessary to set the temperature to 600 ° C. or higher.
However, in the case of granulating, it is not necessary to make it as fine as in the case of the coating material for the human body skin. For example, the condition used for maintaining the water quality in the natural world is 10 mm or more without any problem, and the filtration during cleaning is about 5 mm. , The size of the granules does not matter.

[0019]

According to the present invention, silk material (100% silk)
Since the carbonized powder (1) is used as a coating material for the outer skin of the human body, it is possible to inexpensively provide a raw material that is light and has good compatibility with the skin and is harmless to the human body. In particular, when used as a raw material for medicinal products, quasi-drugs, cosmetics, etc. that are directly applied to the human body, such as hair dye, mascara, eye shadow, eye line, and color adjustment agents for various cosmetics, the characteristics of silk can be fully utilized and It can be provided as a completely harmless raw material.

Similarly, the wonderful adsorption energy of the original silk is used as a filter agent by carbonizing it, and it is used as a conventional filter agent for beer filtration, water purification, and liquid agent filtration during cleaning. It has several times as many filtration effects as dozens of times depending on the product, and can be expected as an epoch-making material as a filtration purification agent in the future.
