Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for dyeing coffee.

[0002]

BACKGROUND OF THE INVENTION Synthetic dyes can provide a wide variety of hues. However, many natural dyes have gentle and elegant colors, and have a mysterious charm that blends beautifully. Among them, Aizen has been widely used since ancient times, and its color has already become universal. Therefore, on the other hand, there is a tendency to seek a new different hue.

[0003] The types of natural dyes include plant dyes such as red and purple roots, animal dyes such as purple shellfish and sepia, and mineral dyes such as red and patina. And as prior art, Japanese Patent Publication No. Hei 7-96853 of the dyeing method with mate tea,
Japanese Unexamined Patent Publication (Kokai) No. 3-41167 discloses a method of dyeing with sweet potato, and Japanese Patent Publication No. 8-340 for producing a coloring agent from cocoa beans.
No. 1 is known.

[0004] Recently, amateur dyeing of natural dyes using persimmon astringent (shibu), onions and vegetation has been actively performed.
However, the astringency of persimmons has the drawback of darkening due to aging, and the onion also has the disadvantage of flying color, and all have problems in fastness to fading. In addition, for dyeing plants and vegetables, it is necessary to first boil the raw materials to make a dye liquor, which has been a very laborious work. As a result, the indigo dye, whose color fades and astringency increases as it is used, was hardly any commercialized.

[0005] On the other hand, coffee trees are also plants, and fruits and flowers bloom, so that coffee dyeing can be said to be natural plant dyeing.
The powder obtained by roasting the coffee beans is used as a beverage having a high flavor. The cocoa is used for cocoa and chocolate, and is different from coffee. And the color of the coffee is different from the dark blue color of indigo, it has a deep dark brown that is calming and healing.
However, even if it is dyed normally using coffee, it cannot be dyed to this dark color, and even if it is dyed, it has only low robustness, and it was impossible to commercialize coffee dyeing conventionally . The present inventor, who has been a long-time hand-dyed dyer, has spent five years immersing himself in the research and development of this coffee dyeing and has finally confirmed the fading fastness to complete a satisfactory coffee-dyed product. It was something that could be done.

[0006]

SUMMARY OF THE INVENTION In view of the above, the present invention provides a dark brown coffee color that is deep and healing,
An object of the present invention is to provide a method of dyeing coffee for dyeing.

[0007]

In order to achieve the above object, the present invention provides a dyeing method comprising a dyeing liquid manufacturing step, a dyeing step, a mordant step, and a washing / drying step, wherein the dyeing liquid step is packed in a bag. The dyed coffee powder is boiled, and the dyeing material to be dyed is cellulosic fiber made of cotton, hemp, silk, etc., and the dyeing material is processed in a pretreatment process before the dyeing process. It constitutes a dyeing method.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail. The dyeing method of the present invention is applied to a dyeing method including a dyeing liquid manufacturing step, a dyeing step, a mordant step, and a washing / drying step. And the dyeing system is industrial dyeing / printing,
It can be used for handicraft tie-dyeing, yuzen-dyeing, wax-dyeing, sushi-dyeing, drawing-dyeing, dye-dyeing, and misty-blowing dyeing.

The object to be dyed according to the present invention relates to fibers, and the fibers can be applied to dye only cellulosic fibers such as cotton, hemp and silk. The method has no effect. The fibers are made of cotton, hemp, silk, etc., because they may be dyed on cellulose fibers made of paper.

[0010] Among fibers, cellulose fibers are not a protein material like animal fibers, and thus have poor dyeing properties. In addition, coffee is particularly resistant to staining. for that reason,
The method of the present invention is characterized in that a pretreatment step is provided before dyeing. The pretreatment step in the present invention is not merely a dirt removal. There are several methods for this pretreatment step. For example, there is a method of specifically removing oil contained in coffee beans. There is also a method in which a protein is artificially attached to the surface of cellulose fibers by adding soy sauce or treating with protein. Further, there is also a method of performing a cationization treatment by using an alkali agent in combination with a cationizing agent mainly containing an epoxy modified product. In the pretreatment step of the present invention, a treatment method that is effective at any time is selected from the above.

In the dyeing liquid production step of the present invention, the dye of coffee is boiled to prepare a dyeing liquid for the dyeing step. In the case of synthetic dyes, it is easy to make an aqueous solution by dissolving it as it is, but for many natural dyes such as plants, it is necessary to boil the raw materials for a long time to make a dyeing solution, which is conventionally a laborious work. I was

In this respect, the preparation of the staining solution of the present invention is different from the conventional method. Instant coffee can be dyed as it is, but it is expensive and not enough for mass production. Therefore, the method of the present invention is a method in which a powder obtained by grinding coffee beans for a beverage is packed in a bag, and this is boiled to easily produce a dyeing solution. The coffee powder cannot be put on an industrial base unless inexpensive ones are selected.
The active ingredient is retained and collected by a coffee maker.
It is desirable to use expired coffee.

[0013] After the subsequent dyeing step, in the method of the present invention, a mordant step after the dyeing step is indispensable together with the auxiliary treatment by the pretreatment at the previous stage. This is because it is necessary to add a dye component in the dyeing process and cause a chemical reaction with the mordant to develop a color. Therefore, by passing through the mordant process after dyeing in the dyeing process, by compounding with the mordant,
It will be colored to the original color. The mordant can be appropriately selected from commercially available mordants such as ferrous sulfate and potassium alum.

[0014] The dyeing step and the mordant step are repeated several times to dye a deep color. Finally, through a washing and drying process, the fabric dyeing is completed. In addition, the printed product is placed on a pattern using a pattern, and the pattern of the color paste is printed. The material thus dyed is subjected to a cutting and sewing process and is shipped as various dyed products. On the other hand, sewn products may be finished by post-dyeing.

Next, an embodiment will be described with reference to the drawings. FIG. 1 is a flow sheet showing the procedure of each step of the present embodiment.

FIG. 1a shows that the dyeing method of the present invention first requires a pretreatment step. In the pretreatment step in the case of the present embodiment, a cationizing agent containing an epoxy-modified product as a main component (selected from commercially available products) was added to water 200.
Five liters were dissolved per liter, and a dyeing object of 100 m of a cotton cloth having a yarn width was immersed for 30 minutes at 50 ° C. Next, as an alkaline agent, NAOH of 38 ° B.
Immerse in 5 liters for 20 minutes, raise the liquid temperature to 60 ° C,
After 0 minute, it was pulled up and dried.

1 is a printing process. Using a reciprocating flat type large-size printing machine, the pretreated fabric was printed with a color paste pattern using a pattern. The fabric after the form dyeing was dried and finished, and this was used as a pattern printing process.
Any color may be used, but dark brown or the like, which matches the color of coffee, is also preferable because of its chic dyeing. In addition,
The printing step is not necessarily pre-dyed, but may be post-dyed after coffee dyeing.

FIG. 1 shows a dyeing liquid production process. The expiration date coffee powder was packed in a bag, which was boiled to form a dyeing liquor. The bath ratio is 1:20 and can be easily boiled in a short time. Next, 4 in FIG. 1 is a dyeing process using a dye solution. The material to be dyed was immersed in a dyeing solution at 90 to 100 ° C. for 10 minutes and dyed.

FIG. 1 shows a mordant step 5. Ferrous chloride and aluminum acetate were used as mordants in this example. Iron is dark and aluminum is gentle. The mordanting liquid was immersed in the dyed material at room temperature to fix and fix the color with the aid of a mordant. By repeating the above-mentioned dyeing step and this mordant step several times, a deep color can be dyed.

FIG. 1 shows a cleaning step 6. The dyed material is washed with water, neutralized with acetic acid and finished. And 7 in FIG. 1 is a drying step. Also, reference numeral 8 in FIG. 1 is a finishing step, which is a rearranging step by tentering and folding. In the present embodiment, the cloth dyed in this manner is used as the last FIG.
The product is subjected to the sewing process of No. 9 above. The sewing process consists of cutting the fabric and sewing.

The coffee dyed product dyed by the method of the present invention was tested by the Japan Chemical Fiber Inspection Association for other factors such as color fastness. The respective fastness of contamination was as follows. The wash fastness was 5, the acid sweat fastness was 4, the alkaline sweat fastness was 4, and the dry cleaning fastness was 5. Further, the fastness to rubbing when dried was 4.5, but the fastness to light was less than 3. The shrinkage was 2.0% in the vertical direction and 2.3% in the horizontal direction. Among these results, the light fastness showing a low value is the characteristic of the coffee dyeing of the present invention. In other words, in the state of dyeing, it has a dark brown color.
When exposed to fluorescent light in a room, the color changes to a light brown color that is deep and healing. This is the same phenomenon that the indigo dyed product just discolors and astringency increases as it is used. Therefore, after the drying step, an irradiation step of applying an ultraviolet lamp may be added.

The coffee dyed product dyed by the method of the present invention can be made into a rancho mat, a coaster or a table center. It is also used for drawstring covers and cushion covers, as well as child cushions. Other goodwill, T
They are also used in shirts, which are post-dyed after sewn products, as well as jackets, blouses, hats and pants. It is also used in apron and parasol fabrics. When used for a nem plate, it is a cloth, but it is also possible to dye a cellulosic fiber made of paper with a hanging tag or the like.

[0023]

According to the dyeing method of the present invention, coffee dyeing, which was conventionally considered to be insufficiently dyeable, can be dyed to a desired dark color.

The coffee-dyed product dyed according to the process of the present invention has a soothing, soothing, deep natural dark brown color. In addition, there is a pleasure that the more you use it, the more discolored it becomes. Other robustnesses are large enough.

The coffee-dyed product dyed by the method of the present invention has an antibacterial property, a deodorant property, an insect repellent property, an antioxidant property, a warming / humidifying effect, and a repellent effect, and can provide an environmentally friendly product. .
