The main objective in dying antron fleece (as with most dying projects) is to get even color. We use RIT dyes and have always had success with them. The following tips should help you achieve the desired results.
Hand dye the fleece. Most packages of dye include instructions on how to dye fabrics using a washing machine. As a general rule, we recommend not dying antron fleece according to these instructions. Dying the fleece by hand is the safest way to achieve quality results.
Use a large amount of water. Use a large amount of water compared with the fleece. We recommend using a large plastic storage container in which to dye a normal sized project. It is not necessary to use boiling water. Most folks can use their hottest tap water.
Soak the fleece. Before lowering the fleece into the dye bath, soak it with clean water. Try not to squeeze the water out. Place the fleece quickly into the dye.
Do not twist the fleece. Do not fold or twist the fleece. Just like a tie-dyed t-shirt, if the fleece is folded or twisted, the dye will not take in those areas. You will need to gently agitate the dye bath to ensure even coverage. Do not overwork the fleece, that is allowing it to rub against itself excessively in the dye bath, as this will also cause the fleece to pill. (Pilling is when a fabric becomes rough with or mats into little balls.)
Multiple dips aid in even coverage. Instead of a single “dip” with a strong color, make multiple dips in a more diluted bath of dye, darkening the fleece little by little until the desired color is achieved. More dye can be added to the bath at intervals as well to achieve the desired result. This method works especially well when dying darker colors.
Rinse the fleece. After the fleece has been dyed the desired color, remove it from the dye bath. Rinse under running water until the water squeezed from the fabric is clear. Lay the fleece flat to dry overnight.
Avoid pilling. Pilling may occur if the material is over-worked in the dye bath, or is machine dried. Drying antron fleece in a dryer will without exception cause the fleece to pill, partly from overheating and partly from being overworked. If your fleece has pilled, not all is lost. A solution for de-pilling your fleece will be discussed in a subsequent post.
