Process of Tie - dye

In  Tie & Dye the basic process is to tie up the required material before applying dye , then the dye only reaches part of the area to which it is applied.
The boundaries of the dyed and non-dyed areas are usually rather blurred, as the dye has begun to soak into the non-dyed sections.

During tie-dyeing, if a good fiber reactive dye is used, a chemical reaction takes place which permanently bonds the colorful dye to the fabric, making tie-dye safe to wash amongst other, non-tie-dyed clothes once the excess dye has been removed. As the name suggests, the fabric is tied, usually with string or rubber bands, after being folded into a particular pattern. Some areas, where the textile is tied and in inner parts of folds, do not absorb dye as readily, forming a pattern. This is known as a resist technique.
