The process of dyeing jeans in blue
As blueprints are both soluble and insoluble substances in the water. For painting jeans you need to purchase a soluble dye. It can be Indigo-Carmine, Prussian blue, soluble blue Parisian, blue aniline dye. Prussian blue dissolves in water only in the presence of oxalic acid. Aniline dyes are usually the most expensive. They have good paintability, but can discolour in the sun. Some aniline dyes after using the iron become red. Among the aniline dyes that are suitable for the production of blueprints: methyl, methylene blue, and wool.
Ultramarine refers to insoluble species of the blue. It's a pretty cheap product. You should know that soluble dyes color the fabric is much more uniform than insoluble.
To make the solution blue need in accordance with the instructions on the package. Because some things are colored in the wash in blue and some in the rinse cycle. The approximate consumption of such blueprints: 0.3 grams to 1 kg of clothing. Stir the powder into cold water and then pour the mixture into warm water. When painting work is the rule: the richer you want shade, there should be less water.
In order to dye jeans, place them in the solution for two hours, at least. After this just dry.
Before painting be sure to wash jeans: they must be absolutely clean. Immerse the jeans in a container of methylene blue in the expanded state. If they are, fold them in half. In this case, make sure that the water is evenly soaked jeans, because there is a risk that they will turn smoothly. Jeans should not look out of the pelvis.
In the water, try to dissolve all the clots blue. If they don't disperse, pour on them warm water (+30°C). If you want to color jeans turned out to be more intense, leave them in the basin in two hours, and all night.
If you want to paint firmly fixed, add the solution of blue a couple of tablespoons of salt with slide. You can assign the painting, rinsing the jeans in a vinegar solution. This should be done after soaking the jeans in blue. Pour 5 tbsp. of vinegar in 10 litres of water. If the fixing ability is insufficient, increase the amount of vinegar. Note that the blue dye fades very quickly. Most likely, after a couple of washings the painting will need to be repeated.
The most persistent are acrylic paints water based. They can be easily diluted with water. But they wash off until the first drying. Then to wash the thing will be difficult. Acrylic paints have a very wide range of shades.
