[0010]

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.

[0011] In general, plant dyeing has a limitation that it does not necessarily lead to the expression of new functionality, although it is in line with the nature-oriented tendency.

[0012] Japanese Patent Application Laid-Open No. 1-132 considering the expression of functionality.
The dyeing method of Japanese Patent No. 886 discloses a method of adding far-infrared radiation by quartz porphyry, heat retention, cold insulation or insect retention by a plant extract by adding quartz shale and a plant extract to a dyeing solution with a natural dye or a synthetic dye. Although it is designed to exert a shelter effect, the adhesion of quartz shale to textiles impairs the feeling, and when a natural dye is used as a dye, the dyeing fastness is inevitable.

The vegetable dye disclosed in JP-A-53-69226 is only characterized in that a conventionally used solid vegetable dye is pulverized.

Although the dyeing method disclosed in JP-A-1-124691 is suitable for underwear to be directly applied to the skin,
It is only safe because it uses food as a raw material, and it does not attempt to positively express its functionality.

Under such a background, the present invention has a unique color tone and texture with a natural feel, has good dyeing property, high dyeing fastness, and further has excellent antibacterial property and ultraviolet ray blocking property. It is an object of the present invention to provide a dyed fiber product that has the above-mentioned properties and is also effective for improving chills and the like, and a method for producing the dyed fiber product.

[0016]

The dyed fiber product of the present invention is tannic acid-treated and dyed with an extract of Diou.

In the method for producing a dyed fiber product of the present invention, the fiber product is contacted with a pretreatment liquid containing tannic acid to be treated with tannic acid, and if necessary, fixed with tartar stone, and then a mordant. The tannic acid is fixed and mordanted by contact with a mordant solution containing the dye, and then the fiber product after the mordant is contacted with the dye solution containing the extract of Diou to carry out a dyeing reaction.

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,
Natural fibers such as silk and wool, or blended products of these natural fibers and chemical fibers, mixed woven products, knitted products, etc. are optional, but especially the conventional dyeing with plants has poor dyeability and low fastness. One of the features of the present invention is that it can be applied to cotton and hemp.

In the present invention, desizing, scouring, bleaching, etc. are carried out if necessary, and then the fiber product is first subjected to a tannic acid treatment by contacting with a pretreatment liquid containing tannic acid.

As the tannic acid, a purified one can be used, but it is also preferable to use 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 as it is. 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 during the tannic acid treatment is about 10 to 100 times (particularly about 20 to 60 times) the weight of the fiber product,
The bath temperature is about 50 to 95 ° C (especially about 60 to 90 ° C), the treatment time is about 10 minutes to 2 hours (especially about 20 minutes to 1.5 hours), and the tannic acid concentration is 5 to the weight of the textile product. 20
Although it is often about 10% by weight, it is not necessarily limited to this range.

After the tannic acid treatment, 0.2 to 1 of tartarite (antimony potassium tartrate) is used to fix the tannic acid.
It is preferable to bring the solution into contact with a solution of about 0% by weight (based on the weight of the textile product), but since the fixing of tannic acid can be achieved by a mordant step which is the next step, the fixing step of tannic acid with tartar is It can be omitted.

After the tannic acid treatment, tannic acid is fixed and mordanted by contacting with a mordant solution containing a mordant. This step is important, and if this step is not performed, the dyeing property and dyeing fastness in the next dyeing step will be insufficient.

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, azalea ash, and swede ash. In addition to aluminum ions, these plant ashes contain other metal ions and alkaline substances useful for dyeing.

With or in place of these plant ash, aluminum acetate, aluminum sulfate,
Aluminum salts such as aluminum chloride, alum, burnt alum and potassium alum, and alumina mordants such as commercially available aluminum liquids can also be used. 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 general, as a mordant for dyeing plants, in addition to the above-mentioned plant ash and alumina mordant (aluminum salt), iron mordant (iron salt), copper mordant (copper salt), tin mordant (tin salt), chromium mordant (chromium salt). ) Is known,
Although dyeing itself is possible with these mordants, the above-mentioned plant ash and alumina mordants are preferable for the purpose of the present invention. The iron mordant is preferably added to the extract of Diou at the time of the dyeing reaction in order to adjust the color of dyeing as described later.

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 usually about 10 minutes to 1 hour, but it is not necessarily limited to this range.

After the tannic acid treatment and the mordant treatment, the textile is dyed by contacting it with a dyeing liquor containing the extract of Diou. As a result, dyeing is performed with a color tone that is a mixture of dark brown and purple.

It is also preferable to dye the fiber product after tannic acid treatment and mordant by contacting it with a dyeing liquor containing an extract of Diou and an iron mordant. In this way, dyeing with a color tone like purple to black brown. Is done. Examples of the iron mordant (iron salt) include iron wood acetate, ferrous sulfate, iron nitrate, ferrous acetate, and iron wood acetate.

[0032] Diou (ground yellow) is the root of Acacia dioica of the family Scutellariae or its genus, has an elongated spindle shape, and has a deep flute and a constriction. The outer surface and cross section are yellowish brown to blackish brown. The root of the dio is called the dough yellow or the fresh ground yellow, and the dried one is called the dry ground yellow, and the one that is steamed and processed is called the ripe ground yellow. Jihuang is listed as an elegant item in Shenno Honso Sutra,
It has been said for a long time that blood supplements and tonics are effective. The extract of this dio in water or an organic solvent (alcohol etc.) is used as a dye.

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, appropriate post-treatments such as soaping and washing with water are carried out, followed by natural drying or hot air drying.

By carrying out the above steps, a dyed fiber product treated with tannic acid and dyed with an extract of Diou can be obtained.

[0036]

[Function] When the tannic acid treatment reaction and mordant (especially mordant with plant ash) are carried out prior to the dyeing reaction, the dyeing reaction with the dio extract is made smooth and the binding between the active ingredient in the dio and the textile product is carried out. Is reliably performed, and deep dyeing is possible, and dyeing fastness is extremely high.

[0039] The dyeing with the extract of Diou gives a unique color tone and texture with a natural feeling, and since the active ingredient in Diou is fixed, it has a unique action effect that it is effective in improving chills and the like. Is played.

Further, by staining with the extract of Diou,
It was found that an excellent action of blocking ultraviolet rays was obtained.
The UV cut rate is as high as 90% or more based on the fabric before dyeing.

In addition, the dyed textile was found to have excellent antibacterial properties. This is due to the antibacterial action of tannic acid fixed to the textile product. In addition,
In general, the antibacterial effect does not appear even after dyeing with tannic acid, so it is considered that the dyeing reaction with the extract of Diou has the effect of eliciting the antibacterial property of 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 dyed fiber product of the present invention is used in contact with the skin, for example, underwear, pantyhose, brassieres, shirts, nightwear, sheets, gloves, hats, sports supporters, swimwear, bandages, sick people. It is particularly useful as an interior material or surface material for clothes, masks, footwear, watch bands, socks and the like. Further, since it has fashionability, it does not matter even if it is used for applications that do not come into direct contact with the skin.
