This pre-soak raises the pH of your shirt to about 10.5. This increases the amount of negative hydrogen ions in the environment of your shirt. The covalent bonding that will take place uses these hydrogen ions in the reaction. This presoaking allows the reactive dye to work in room temperature. After you have pre-soaked your shirt for at least 4 hours, you can tie dye your shirt with the fiber reactive dyes. After you tie dye your shirt, you must wrap it in paper towel and put it in a gallon sized bag and wait 24 hours. This will allow the colors to sink into the shirt and allow the dye and the fiber to bond together. After you have waited 24 hours, you must rinse your shirt and wring it out several times. After this, you must put it in the washing machine to wash off the extra dye that did not bond to the fiber. Now you have successfully tie dyed a shirt with fiber reactive
