[0001]

FIELD OF THE INVENTION The present invention relates to a Reishi dyed fiber having a natural hue and texture, good dyeing properties, high dyeing fastness and antiallergic and antibacterial properties. It relates to a method of manufacturing a product.

[0002]

2. Description of the Related Art Although natural dyes have been destroyed by synthetic dyes for a long time, plant dyeing has unique astringency, calmness, luster, and texture that synthetic dyes cannot produce, so today's natural orientation is increasing. It is being reassessed.

Natural dyes applicable to plant dyeing include
Kuchinashi, Ukon, Kihadada, Tsuyukusa, Ai, Safflower, Enju, Asen, Plum, Sakura, Pomegranate, Tea, Mokkoku, Akane,
Suou, purple root, quintuplet, Hisaki, wormwood, Susuki,
Chrysanthemum, Nanten, Hiiragi Nanten, Kuzu, Kunugi, White oak, Gensho, Yarrow, Yamamo, Walnut, Logwood, Kashiwa, Morning glory, Rose, Saffron, Marigold, Grape, Eggplant,
Acorn, Kariya, Azalea, Uren, Hamanasu, Cedar,
From a wide variety of plants, including cypress, pine, hiiragi, peach, dogami, hagi, persimmon, chestnut, saffron, red beans, black beans, hazelnut, suou, goldenrod, onion, yew, alder, lobster, and sleeper. The resulting dye is used.

Several proposals have been made for using microorganisms, fungi, algae or moss or their products as dyes.

Japanese Unexamined Patent Publication (Kokai) No. 2-234988 discloses a dyeing method using shiitake mushrooms in which shiitake mushrooms are boiled to extract a dyeing solution, the cloth is dyed, and a color is fixed and fixed using a mordant. This method is related to "post-mordanting", and it is described that the lye of plant ash is used as the mordant solution.

In JP-A-1-132886, fine powder of quartz shale is mixed and dispersed in a water-soluble acrylic resin liquid, hot water is injected into this dispersion liquid, and a plant extract and a dye are added thereto. A method for dyeing textiles is described, in which after mixing and soaking the textiles, ordinary post-treatments such as soaping and drying are performed.

This method is intended to enhance the heat retaining property of textiles by utilizing the far infrared radiation effect of quartz porphyry, and it is further used in combination with a plant extract for heat retaining, cold retaining or insect repellent. A function is added. As a plant extract,
When the purpose is to keep warm, garlic, chili pepper, mackerel sprinkles, licorice, mountain bean root, board quinoli, board uddo, tender bean, concree, lacquer fruit, aloe leaf, chlorella, etc. For that purpose, citrus fruits such as tangerines and oranges are used, and for the purpose of insect repellent, bark and leaves of trees such as cypress are used. However, plant extracts are not used as dyes, but as dyes, natural dyes (used for plant dyeing) and synthetic dyes are used separately.

In the Nikkei Sangyo Shimbun, published on May 22, 1991, stalks of Reishi are finely cut to make squeeze soup, and the soup is used to subdye the fabric and then colored with an artificial dye. An article in which silk is dyed by sprinkling Reishi spores on is published.

[0009]

In addition to the complicated dyeing process, the conventional dyeing of vegetation is inferior in dyeing property and fastness to dyeing, especially to cotton and hemp, and the individuality peculiar to the substance is maintained. There is a weak point that it is poor in nature, and this is the biggest problem of plant dyeing.

[0010] In general, plant dyeing has a limit that it is not necessarily connected to the expression of new functionality, although it is in line with the nature-oriented tendency. The shiitake dyeing described in Japanese Patent Laid-Open No. 2-234988 is limited to the fact that it is dyed with plants using a plant rare in this respect. The fact that dyeing does not lead to new development of functionality is the same in the case of dyeing with a synthetic dye.

The dyeing method disclosed in Japanese Patent Laid-Open No. Hei 1-132886 comprises adding quartz shale and a plant extract to a dyeing solution with a natural dye or a synthetic dye, and irradiating far-infrared rays with the staghorn and vegetative. The extract is used to keep warm, cool, or repel insects, but the adhesion of quartz shale to textiles impairs the feel, and when a natural dye is used as a dye, the dyeing fastness is improved. I cannot help being inferior.

Although the technology described in the article of Nikkei Sangyo Shimbun on May 22, 1991, is under-dyed with Reishi, this under-dying is, so to speak, a pretreatment and the dyeing itself is performed with an artificial dye. There is. In addition, in this article, there is a description that "the reishi is blue, red, yellow, purple and discoloration are piled up" and that "the stalk of the reishi is finely cut to make simmered soup". It is known that there are 6 types of turf, blue turf, red turf, yellow turf, white turf, black turf, and purple turf, but there is no fact that they will continue to discolor, and the "umbrella" part, which has many active ingredients, is not used. There are some questions in facts and technical points, such as using a stem part that is relatively small in utility. After all, the dyed product in this article is not dyed with ganoderma to give a “ganoderma color”, but simply pretreat the fabric with ganoderma stalks of ganoderma, It only gives a high-class feeling by sprinkling.

Under such a background, the present invention has a unique hue and texture with the natural feeling of Reishi, has good dyeing property, has extremely high dyeing fastness, and further has antiallergic property. It is an object of the present invention to provide a method for producing a Reishi-dyed textile product having antibacterial properties.

[0014]

A first method for producing a Reishi dyed textile product of the present invention is to perform a cationization treatment by bringing the textile product into contact with a pretreatment liquid containing a cationizing agent, and then the mycelium of Reishi. It is characterized in that the dyeing reaction is carried out by contacting with a dyeing solution containing an extract of a body or fruiting body.

The second method for producing a Reishi dyed textile product of the present invention is to bring the textile product into contact with a pretreatment liquid containing a cationizing agent for cationization treatment, and then to bring it into contact with a treatment liquid containing tannic acid. It is characterized in that it is treated with tannic acid and then brought into contact with a dyeing solution containing an extract of the mycelium or fruiting body of Reishi to cause a dyeing reaction.

The third method for producing a Reishi dyed textile product of the present invention is to treat the textile product with a pretreatment liquid containing a cationizing agent for cationization, and then, if necessary, a treatment liquid containing tannic acid. Contacting with tannic acid, then contacting with a mordant solution containing a mordant, and then contacting the mordant fiber product with a dye solution containing an extract of the mycelium or fruiting body of Reishi, for dyeing reaction. It is characterized by.

The fourth method for producing a Reishi dyed fiber product of the present invention is to treat the fiber product with a pretreatment liquid containing a cationizing agent for cationization, and then, if necessary, a treatment liquid containing tannic acid. Mordant containing mordanting agent and extract of Reishi mycelium or fruit body-
It is characterized in that the mordanting reaction and the dyeing reaction are carried out simultaneously by contacting with a dyeing solution.

The present invention will be described in detail below.

The fiber products in the present invention include fibrils, threads, piles, cotton-like materials, woven fabrics, knitted fabrics, non-woven fabrics, and flocked fabrics. In addition, paper products, wood products, etc. are also included in the textile products referred to in the present invention.

The materials of these textile products are cotton, linen,
Silk, wool, etc., or blended products of them and chemical fibers,
Although it is optional such as a mixed woven product and a mixed knit product, one of the features of the present invention is that it can be applied to cotton and hemp, which have poor dyeing properties and low fastness, particularly in conventional dyeing with plants.

In the present invention, desizing, scouring, bleaching, etc. are carried out if necessary, and then the fiber product is first subjected to a cationization treatment by contact reaction with a pretreatment liquid containing a cationizing agent.

As the cationizing agent, various commercially available cationizing agents can be used. The cationization treatment is performed in the presence of alkali.

The bath ratio during the cationization treatment is about 10 to 100 times the weight of the fiber product, the bath temperature is about 50 to 95 ° C. (particularly about 60 to 90 ° C.), and the treatment time is about 10 minutes to 2 hours. (Especially about 20 minutes to 1.5 hours)
The concentration of the cationizing agent is set appropriately.

After the cationization treatment, the tannic acid treatment may be carried out by bringing it into contact with a treatment liquid containing tannic acid, if necessary. The method of performing the tannic acid treatment after the cationization treatment is advantageous in terms of improving the washing fastness and the antibacterial property.

As the tannic acid used in the tannic acid treatment, a purified tannic acid may be used, but an extract of a natural plant having a high tannic acid content such as quintile, gallic or the like or a semi-purified product thereof. It is also preferable to use The quintile contains about 60-75% tannic acid and the gallate contains about 55-65% tannic acid. Purified tannic acid is also obtained by crushing quintet or gallic and extracting with a mixture of ether and ethanol, adding water to the leachate to transfer tannic acid to water, and further purifying it if necessary. Therefore, it can be said that it is a natural product.

The bath ratio, bath temperature and treatment time during the tannic acid treatment can be the same as in the case of the cationization treatment. The tannic acid concentration is 5 to 20 relative to the weight of the textile product.
Although it is often about 10% by weight, it is not necessarily limited to this range.

After the tannic acid treatment, in order to fix the tannic acid, it can be brought into contact with a solution of about 1 to 3% by weight (based on the weight of the textile) of tartarite (antimony potassium tartrate). However, since the fixing of tannic acid can be achieved by the mordant step when a mordant step is provided as the next step, the step of fixing the tannic acid by tartar can be omitted.

After the tannic acid treatment, the tannic acid can be fixed and mordanted by contacting with a mordant solution containing a mordant. This step is an optional step, but it is preferable to provide this step in terms of dyeing property and dyeing fastness in the next step, the dyeing step.

Here, as the mordant, it is preferable to use plant ash (wood ash or straw ash) such as camellia ash, sawathagi ash, hisakaki ash, kunugi ash, red ash, and swede ash. These plant ashes contain, in addition to aluminum ions, other metal ions and alkaline substances useful for dyeing.

It is also possible to use aluminum salts such as aluminum acetate, aluminum sulfate, aluminum chloride, alum, burnt alum and potassium alum, and an alumina mordant such as a commercially available aluminum liquid. Further, an alkali such as calcium carbonate, sodium carbonate, calcium hydroxide or sodium hydroxide can be used in combination with the above-mentioned plant ash, aluminum salt and aluminum liquid.

In addition to the above mordants, in some cases, iron mordants (iron salts such as iron acetate wood, ferrous sulfate, praised iron, and ferrous acetate), copper mordants (copper salts), tin mordants (tin salts). ),
Chromium mordants (chromium salts), cobalt mordants (cobalt salts) and the like can also be used.

The bath ratio at the time of mordant is 10 with respect to the weight of the textile product.
˜100 times (particularly about 20 to 60 times), the bath temperature is room temperature to boiling temperature, and the treatment time is often about 10 minutes to 1 hour, but not limited to this range.

After the cationization treatment (after the tannic acid treatment, after the mordanting, and when the mordant was further performed), the fiber product was treated with a dyeing solution containing an extract of the mycelium or fruiting body of Reishi. A dyeing reaction is caused by bringing them into contact with each other. This gives a dyeing of a unique color tone.

Here, Ganoderma Kucidum is a fungus belonging to Basidiomycetes, Rhododendronaceae, Rhododendronaceae, and Ganoderma lucidum, and the genus is clearly different from the genus Sarnopsis moss. The well-known folk medicine, Sarcophagous moss belongs to the genus Sarcophagous, and is different from Reishi in appearance, shape, and medicinal effect.

Regarding Reishi, six kinds of blue grass, red grass, yellow grass, white grass, black grass, and shishiba are available in Shenno Honso Sutra, which is the original source of Kampo medicine.
The types are listed and the medicinal effects of each are listed. Thus, Ganoderma lucidum is one of the Kampo medicines that have been used in Chinese medicine for a long time, and more recently, antiallergic action, macrophage activating action, antitumor action, blood pressure lowering action, hypoglycemic action, and anti-hyperlipidemic action. It has been reported in the literature that it has a pharmacological activity such as a blood sugar effect and an antithrombotic effect.

As the raw material Reishi, mycelia or fruiting bodies are used. When the mycelium or fruiting body of Ganoderma lucidum is extracted with water or / and a hydrophilic organic solvent (alcohol etc.), the active ingredient (glycoprotein conjugate etc.) is leached to obtain an extract. If necessary, dialyzate or ultrafilter this extract,
Furthermore, extraction may be performed.

The bath ratio during the dyeing reaction treatment is about 10 to 100 times (particularly about 20 to 60 times) the weight of the textile product, and the bath temperature is about 50 to 95 ° C. (particularly about 60 to 90 ° C.), Processing time is about 20 minutes to 3 hours (especially about 30 minutes to 2 hours)
However, it is not necessarily limited to this range. The dye concentration can be selected from a wide range depending on the purpose.

After completion of the dyeing step, after-treatment such as soaping and washing with water is appropriately performed, and then natural drying or hot air drying is performed.

In the above, mordanting is carried out by contacting with a mordanting solution containing a mordanting agent, and then contacted with a dying solution containing an extract of the mycelium or fruiting body of Ganoderma lucidum. The mordant reaction and the staining reaction may be carried out at the same time by contacting with a mordant-staining solution containing a mordant and an extract of the mycelium or fruiting body of Reishi.

By carrying out the steps described above, a Reishi dyed fiber product which is cationized (further tannic acid) and dyed with an extract of Reishi mycelium or fruiting body can be obtained.

[0041]

[Function] When the cationization treatment reaction (or the tannic acid treatment reaction, and further the mordant reaction) is performed prior to the dyeing reaction with the Reishi extract, the dyeing reaction with the Reishi extract is facilitated and The binding between the active ingredient in the turf extract and the fiber product is ensured, a unique color tone is obtained, deep dyeing is also possible, and dyeing fastness is extremely high. And since the active ingredient in Reishi is fixed to the dyed fiber product, it is kind to the skin, and has an antiallergic effect such as a skin conditioning effect and an effect of suppressing itch.

In addition, this Reishi dyed textile has been found to have favorable antibacterial properties. This is due to the antibacterial action of the Reishi extract (or it and tannic acid). Since this antibacterial action is a bacteriostatic action that does not affect the human body's ecosystem, it can also be used medicinally for a human body having a skin disease or itch.

Therefore, the ganoderma dyed textile product obtained by the method of the present invention can be used in contact with skin, for example, underwear,
It is particularly useful for shirts, nightwear, sheets, gloves, hats, sports supporters, swimwear, bandages, clothing for the sick, masks and the like. Further, since it has fashionability, it does not matter even if it is used in a case where it does not come into contact with the skin.
