Description

{Natural Dyeing Method Using A Soapberry}

The present invention relates to a natural dyeing method, and more particularly, to a natural dyeing method using a non-treated wood using a low-temperature decompression concentration method with improved dyeability 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.

Mushroom tree  Dye extraction step

The dye is extracted from the moth tree. At this time, the process of extracting wood-free wood dyes uses a low-temperature decompression concentration method.

That is, after putting the moisture-free wood in the pressure-reduced container, pour the alcohol and pour the alcohol, and then open the lid and extract the heat-insulating wood dyes 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, mothers are known to be good at removing fever, removing parasites, fever due to colds, pertussis, and asthma.

Bleach  Deposition step

The dyestuffs are immersed in a mushroom salt solution in which the mushroom wood dyes are dissolved, and simultaneous mordanting is carried out. At this time, the dyed material is dyed in an immersed woody salt solution at 80 to 100 ° C for 10 to 20 minutes.

Here, the dye is obtained by concentrating the extract of the mushroom tree in 5% solution. The dyed material is a 100% cotton towel, and the bath ratio (weight ratio of the dyed material 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

Five grams of alcohol is poured into a pressure-reduced container, 500 l of alcohol is poured into the container, and the lid is closed. Then, the pressure-sensitive wood dyes are extracted at 40 ° C for 2 hours under a pressure of 0.01 MPa. Concentrate the extracted wood-free dye to 5% solution, filter it with filter paper (Whatman No. 2), and use it for dyeing.

Then, a 100% cotton towel (13 g each of the test pieces) is immersed in the circulating saline 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.

After that, dyeing was carried out for 15 minutes in a mushroom-free salt solution at 90 ° C while simultaneously mushing 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 fermented saline solution was set to 30 캜.

Comparative Example  2

In Example 1, the temperature of the non-treatment wood salt solution is set to 60 캜.

Comparative Example  3

In Example 1, the hot-water extraction was performed on the non-treated wood dye extract.

At this time, in the case of the mother-of-pearl wood dye, 500 g of mushroom wood was put into a stainless steel container, 5 L of water having a pH of 7 was poured, and the mixture was heated at 100 캜 for 30 minutes.

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 10RP6 / 6 hazy pink Comparative Example 1 10RP7 / 8 pink Comparative Example 2 10RP7 / 10 pink Comparative Example 3 ·

As shown in Table 1, the color of the cotton towel fabric (Example 1) dyed at 90 ° C with the use of the non-treated wood dyes extracted by different extraction methods was examined. As a result, it was found that dyeings dyed at 90 ° C (Example 1) , Comparative Example 2 and Comparative Example 1 in that order.

Therefore, it can be seen that dyeing with a temperature of 90 ° C of the mother-of-pearl salt solution has the best dyeing effect.

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 1.5 Comparative Example 2 1.3 Comparative Example 3 1.7

As shown in Table 2, the occurrence of staining of a cotton towel fabric (Example 1) dyed at 90 ° C with a non-treated wood dye extracted by a different extraction method was examined. As a result, And it was found that the occurrence of the most stain was less when staining at 90 ° C (Example 1).

Therefore, it can be seen that uniform dyeing of the dyed material can be obtained by dyeing at 90 ° C using an airless wooden dye subjected to low-temperature decompression extraction.

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 3-4 2 Dry cleaning
Fastness Fading color 4-5 3 3-4 3 pollution 4-5 3-4 3-4 4

As shown in Table 3, the fastness of the cotton towel fabrics (Example 1) dyed at 90 ° C with the non-treated wood dyes extracted by different extraction methods was examined, and as a result, the fastness of the fabrics dyed with hot water extraction (Comparative Example 3) , And dyeing at 90 占 폚 (Example 1).

Therefore, it can be seen that dyeing at 90 ° C using an airless wood dyestuff extracted with low-temperature decompression gives excellent fastness to the dyed goods.

INDUSTRIAL APPLICABILITY As described above, the present invention is advantageous in that it is possible to expect a functional effect according to a non-treating tree by using an alder tree which is a natural material.

Further, the present invention has an advantage that a fabric excellent in dyeing property and fastness can be obtained while obtaining the functional effect of the non-treated wood.

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.
