Description

{Natural Dyeing Method Using A Japanese Pagoda Tree}

The present invention relates to a natural dyeing method, and more particularly, to a natural dyeing method utilizing a bean-burning method using a low-temperature decompression concentration method with improved dyeing properties and fastness.

 Natural dyeing is called natural dyeing in which plant extracts, mineral powders and animal derived dyes are used to dye cloth or the like. Natural dyeing can reduce water pollution and dyeing wastewater during dyeing, and many natural dyes have functionality such as antibacterial, deodorizing and antiallergic properties. Therefore, fabrics dyed with natural dyes can expect functional effects such as antimicrobial activity, deodorization and antiallergic properties. In addition, the color of cloth dyed with natural dyes is natural, which gives comfort and stability, so it has a high leading edge and low eye fatigue.

Natural dyeing has these advantages, but it has a problem in that it is difficult to commercialize because the dyeing unevenness and fastness are less than dyeing with synthetic dyes.

Therefore, there is a need to develop a natural dyeing method capable of improving the non-uniformity and fastness of dyeing.

FIG. 1 is a flowchart for explaining a natural dyeing method according to the present invention. Referring to FIG. 1, a natural dyeing method according to the present invention will be described as follows.

Cow  Dye extraction step

Dye is extracted from the seedling. At this time, for the extraction of the coloring dye, a low-temperature decompression concentration method is used.

In other words, after sparging is put into a pressure-reducing vessel, the alcohol is poured, then the lid is closed, and the spiked dye is extracted at a pressure of 0.001 to 0.05 MPa for 1 to 3 hours at 35 to 45 ° C. The extracted dye is concentrated to 3 ~ 7% solution, filtered with filter paper (Whatman No. 2) and used for dyeing.

On the other hand, it is known that it has various functional effects such as blood pressure lowering action, capillary strengthening action, antihistamine action, cooperation with vitamin C, anticancer action, anticoagulation, and prevention of hypertension.

Bleach  Deposition step

The dyed material is immersed in a colloidal solution in which the colloidal dyes are dissolved, and simultaneous mordanting is performed. At this time, the dyed material is dyed in a lye of 80 ~ 100 ℃ for 10 ~ 20 minutes.

Here, the dyed product obtained by concentrating the extract solution in 5% liquid is used. The dyed product is a 100% cotton towel, and the bath ratio (weight ratio of the dyed product and water) is 1:30. And mushing is simultaneous mordanting, and as a mordant, alum is diluted to 3% in distilled water.

Bleach  Wash step

Wash the dyed dyestuffs in clear water.

Bleach  Heat treatment step

Heat the washed saline solution.

That is, the dyed material is heat-treated at a temperature of 120 to 180 ° C for 3 to 8 minutes. At this time, iron is used for heat treatment.

Bleach  Drying step

The heat-treated dyed material is naturally dried at room temperature.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to preferred embodiments. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. Of course.

Example  One

After pouring 5 g of the alcohol into the decompression vessel, the lid is closed, and the spiked dye is extracted at 40 ° C for 2 hours under a pressure of 0.01 MPa. Concentrate the extracted keratinizer dye, adjust it to 5% solution, filter it with filter paper (Whatman No. 2), and use it for dyeing.

Then, 100% cotton towel (13 grams per test piece) is immersed in a lye solution. At this time, the bathing cost is 1:30. In addition, mordanting is simultaneous mordanting, and as a mordanting agent, alum is diluted to 3% in distilled water.

Thereafter, dyeing was carried out for 15 minutes at 90 ° C in a saline solution while simultaneous mordanting was performed using a towel paper refined for 10 minutes. After the dyeing is completed, the iron temperature is adjusted to 150 ° C, followed by heat treatment for 5 minutes, followed by natural drying in the shade.

Comparative Example  One

In Example 1, the temperature of the colloidal solution is set at 30 캜.

Comparative Example  2

In Example 1, the temperature of the denitrification solution is set at 60 캜.

Comparative Example  3

In Example 1, the spike dye extraction is subjected to hot water extraction.

At this time, in the case of the dyed dye, 5 g of the water having a pH of 7 was poured into a stainless steel container, and the mixture was heated at 100 ° C. for 30 minutes to extract hot water.

Experimental Example  1: Evaluation of dyeability

When evaluating dyeability, the color of dyeing cloth is classified as' standard guide for public design coloring; Standard Color Name " (issued by the Korean Institute of Standards and Technology).

Table 1 is a table for evaluating the dyeability of Example 1 and Comparative Examples 1 to 3.

Color Example 1 10Y9 / 10 yellow Comparative Example 1 · Comparative Example 2 · Comparative Example 3 10Y9 / 6 light yellow

As shown in Table 1, the color of the cotton towel fabric (Example 1) dyed at 90 ° C with the spiked dyes extracted by different extraction methods was examined, and it was pale yellow when dyed with hot water extraction (Comparative Example 3) The dyed with the extracted dye (Example 1) was relatively dark yellow.

Therefore, it was found that dyeing was better than dyeing by hot water extraction.

Experimental Example  2: Evaluation of occurrence of stain

The areas of stains generated in Example 1 and Comparative Examples 1 to 3 were measured to compare the occurrence of stains. Comparative Example 1 to 3 were relatively shown based on Example 1 (one point).

Stain occurrence Example 1 One Comparative Example 1 1.6 Comparative Example 2 1.3 Comparative Example 3 1.8

As shown in Table 2, the occurrence of stains of the cotton towel fabric (Example 1) dyed at 90 ° C with the extracted dyed dyes having different extraction methods was investigated. As a result, the occurrence of stains was much higher than that of stained with hot water extraction (Comparative Example 3) , And it was found that the occurrence of the most stain when dyeing at 90 ° C (Example 1) was small.

Therefore, it can be seen that uniform dyeing of the dyed materials can be obtained by dying the dyed dyes extracted at low temperature under reduced pressure at 90 ° C.

Experimental Example  3: Fastness  evaluation

Item Grades according to dyeing temperature Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Light fastness 4 3 3 2 Dry cleaning
Fastness Fading color 4-5 3 3-4 3 pollution 4-5 3 3-4 4

As shown in Table 3, the fastness of the cotton towel fabric (Example 1) dyed at 90 ° C with the extracted cotton dyes different from the extraction method was examined, and as a result, It can be seen that the most excellent fastness is obtained when dyeing at 90 ° C (Example 1).

Therefore, it can be seen that when dyeing at 90 ° C using a spiked dye subjected to low-temperature decompression extraction, excellent fastness to the dyed materials can be obtained.

INDUSTRIAL APPLICABILITY As described above, the present invention has an advantage in that a functional effect according to the size can be expected by using a natural material.

In addition, the present invention is advantageous in that a fabric excellent in dyeing property and fastness can be obtained while obtaining a functional effect of beating.

The fabrics manufactured according to the present invention having the above advantages are highly likely to be used industrially by expanding the demand of the fabric and expanding the market of the fabric through the above-mentioned advantages, and it is possible to create high economic value.
