Classification of Natural Dyes and Dyeing İn The Rules That Apply
07:04
Natural painting from nature, from plants and insects that are available by the use of various dyes in the process of painting you made. Plants especially root, stem, leaf, and flowers are used in dried or fresh State for painting or can be pre-processed.
Natural painting are divided into three groups:
1.Direct Painting
2.Dyes and coloring and mordan coloring
3.VAT dyes dyeing dye and cube
-Direct Painting
Direct dyes and mordant the wool kupleme to influence the process directly without the need to paint. For example,the leaves contained in a walnut shell and juglon, wool paints directly without any auxiliary materials. The effect of time and temperature in aqueous solutions of dyes wool and this is negative. If this painting method dyestuff contain basic groups, these protein fibers(wool)with acid groups, acidic groups if the dye contains protein fibres react with the basic groups of these. By forming chemical bonds with the fiber as a result of this dye are connected.
-Dyes and coloring mordant
The majority of natural dyes are mordant dyes creates. Connect the fiber to connect these dyes give good results or even on their own direct and they don't. For this, there is need for a tool to strengthen the provision of such dyes or enable you to connect with. Such substances <mordant> is called. Mordant dye wool yarn with a connecting role between. Mordant for acidic dyes, basic based basic mordant for acidic dyes with properties is required.
Wool, before painting, or mordanlanab during the dyeing process. Mordants or usually they open koyulastirirl colors. For example, paint a bright red color while giving the root SAP mordant, Iron mordant gives a dark red color. Thread how long you wait all mordant painting in bright, beautiful colors are obtained.
-VAT dyes dyeing dye and cube
VAT dyes are insoluble in water. In order to sabitlesebi of these dyes on the fiber, a water-soluble condition must be brought. In this process, through the reduction of dyes in a solution.
MORDANTS and auxiliary materials
Heavy metal salts are the ingredients that are used to understand the Mord wool. Any salt of this type can be used, but for this job the most suitable substance which is also widely used in mordant the wool and the six are as follows:
-SAP
-Chrome
-Sacikibris
-Goztasi
-Tin(II) chloride
-Cream of Tartar
SAP
Formula Kal (SO4)2 – H2O I2 several different chemically distinct compounds can be found in nature in the purity of the stalks.
SAP, the most widely used in traditional Anatolian wool dyeing purple. Almost everywhere can be easily achieved. When retrieving the SAP should be considered to be clean.
Mordanlama is used between 150 to 250 grams of the weight of wool in SAP. For that amount less fine soft wool, very thick and hard thing is suitable for wool. Medium-quality wool 200 g is used for the SAP.
CHROME
Chemical name potassium dichromate, K2CR2O7 formula . In wool dyeing, Sapa compared to darker colors. The quantity of wool of the weight that should be used at 3%, in other words, a weight of 30 g for wool .
When higher rates are used because it affects adversely wool and dyes must be carefully weighed. The method of mordanting with Chrome is not applied. Because it resides in Chrome when free in Solution, causes the precipitation of some dyes.
SACIKIBRIS
Chemical name Iron(II)sulfate-7-water, formula Mar-7 H2O.
Anatolia, also commonly referred to as ‘black paint’ as it is known.
Sacikibris, most of all dyes used in achieving dark colors and blacks. The light fastness is high, but when used in excess for a long time, and the decay of wool causes it to leak .The resulting color is used depends upon the amount of Morgan.
The method of mordanting with la sacikibris is not applied.
Goztasi
In agriculture ,used in the spraying of plants, because it is readily available everywhere. Many dye brown with some interesting non-dark colors. Yesil is used as mordant to make the second.
Tin
Most open and gives bright colors, but these colors of light fastness is low compared with the other Lara Morgan.
Cream Of Tartar
Morgan allows better detection of dyes by facilitating the establishment of the bond between the wool fibers.
Sodium Sulfat
Wool dyes introduced in a help article that allows you to pass through.
THE TOOLS THAT ARE USED IN WOOL DYEING
All equipment will vary according to the nature of the paint job to do.
Fire-resistant glass (payreks) pitcher or a pot-sized containers can be used.
You need a scale for the measurement of precision weights.
Into a one liter glass beaker should include a scale to 100 cm2.The thermometer also among the tools that need to be considered.
.THE RULES THAT APPLY IN DYEING
Wavy mix color wool for the lack of a bath very often and you will need to top to bottom. When water is used, the staining of wool tekornek necessary in order to ensure at least a few times to mix.
Always boiling on a low heat should be done. Fire should be light enough to raise the temperature of the boiling point of water at a time. The duration is usually one hour of boiling. This time is sufficient for stabilization of dyes and wool processing. Worth keeping in the mouth of the container closed to prevent the loss of water. The bath at the end of the boil, allowed to cool down.
After it cools, the wool is rinsed with water and dried. During this time, more of wool washing with pure soap makes it easier for you to dispose of paint, but is not required.
Sudden temperature changes causes it to be wool felt. Into the water seal to prevent wool bathing with the cold. Then the temperature is raised slowly.
All the dyes in water is generally increased than a painting can be made from the first second or even third. The next painting is obtained from the color of the first color, the lighter, more pastel shades. However, each color of paint is reduced to a little more light-fastness.
