Dyes are substances applied in aqueous based solution that is put into fabric to give it color. Dyes are different from pigment because pigments are usually insoluble. Some dyes fade after time because they are not chemically attached to the molecules of the fabric. Dye molecules are all differently unique. The light is absorbed in different ways because they are shaped differently. The result of the color in the dye is different. Usually a third molecule is added to the dye because it helps the dye bond to the fabric. It does this because the added molecule bonds to the molecule of the fabric. There are many different types of dyes. There is synthetic dyes acid dyes, mordant dyes, basic dyes, vat dyes, disperse dyes, and sulfur dyes. Synthetics dyes have many different varieties. These are more popular than natural dyes because of the wide range of colors that comes out of it and they are also cheaper and better than natural ones. Acid dyes are highly reactive soluble dyes that are used to color silk, wool and nylon fabrics. Mordant dyes are resistant to water, light and perspiration. This is usually used for wool. Basic dyes are used with acetic acid to dye acrylic fabrics. Vat dyes are easily applied into fabric because it's not soluble in water and it needs to be compressed in alkaline liquor to get water soluble. Disperse dyes is available as a paste or power, it is used to dye polyester fabrics. Sulfur dyes are used in large quantities, they are applied in two part dyes. First part produced a pale yellow color when the second part uses a sulfur compound to produce dark shades of black. A German photo chemists, Hermann Wilhelm Vogel added dyes to a film that was only sensitive to blue and UV light, that allows the film to capture its color green, this was explored in 1873. In 1907 two French brothers had figured out how to get perfect color for the public called Autochrome. Now a day dyes are widely used in painting, the colors of cyan, yellow, magenta and black combine to form all the color visual that you see printed out.
Tie Dyeing became very popular in the 1950's, but it has been around for many centuries. People used two different types of dye, natural dye from plants and store bought dye that was home man made with chemicals. Five thousand years ago dyes were in use, archeologist established that different types of stamps used for painting fabric in Mesopotamia and India. In one thousand B.C., cloths that were used to wrap up mummies and etc. were found with dye on them in Egypt. Dying techniques possibly trekked through different trade routes from India to Egypt.
Processes of dyeing shirts.
First, get a plane white shirt of your size. Soak the shirt in a soda ash solution, this helps it keep its color. After soaking it for about 15 minutes take it out and squeeze as much of the solution out of the shirt.After squeezing the solution out lay your shirt flat on a table and fold how you want your design to be.
After folding how you want, dye the shirt with the colors you want. Be sure to get the dye in the creases of the shirt as well. Let the shirt sit how about six to eight hours, then wash it under cold water till the water runs clear. Put the shirt in the wash with cold water by its self, then put it in the dyer and you're done! :D
