The result after dyeing is sometimes different than expected. The colors may appear different than on the website or the packaging. Read more about color differences after dyeing with fabric dye.
The picture shows the result of two white cotton T-shirts dyed in the same color bath with the color Sea green. The lower T-shirt is much more blue whereas the upper one is blue only in the tied areas. There, the color could adhere less well.
All fabrics are different. Cotton reacts differently than silk, linen differently than wool etc. Even if we use the same color, the result can be quite different. There may be a difference as to whether or how a fabric was washed before dyeing. Detergents with water-repellent ingredients and bleach can definitely influence the result.
Almost every shade consists of several colors. The basic colors are red, blue and yellow. All other colors are secondary colors. These secondary colors consist of different primary colors.
For example, denim colors appear to be dark blue. However, reds are also found in it. The red with the blue gives jeans a purple undertone. Within shades of grey is often blue and within green is yellow.
When dyeing, the colors penetrate into the fibers of the fabric. If one substance absorbs one color more easily than another, color differences will result. Dark blue can turn purple, gray turns blue and green does not turn green enough.
To avoid disappointment, we recommend that you first test the colors on a small piece of the fabric to be dyed.
Incorrectly reverting colors are less easy. Too light colors are usually pretty good to restore, dark colors are trickier. In these cases, decolorization is important before dyeing.
Decolorization can be made with special products available at drugstores or online.
Decolouring can also be done with chlorine bleach, but keep in mind that you always dilute it before using it on your fabrics. Chlorine affects the fibres when the concentration is too high.
The repeated washing of the fabrics, possibly with a dishwashing detergent helps to completely remove residues of the decolorizer from the fabric, which in turn facilitates the adhesion of the fabric dye and makes recoloring easier.
