iDye comes in two different forms, iDye Natural, and iDye Poly. iDye Natural may be used either in the washing machine or on the stove top. Today's post deals with iDye Natural and the washing machine method. (iDye Poly, and the stove top method will be covered in an upcoming post by guest blogger Alex Preston)
iDye Natural is our simplest dye to work with. iDye Natural works with all 100% natural fibers, whether they are cellulose fibers or protein fibers, including cotton, linen, rayon, or silk., It comes pre-measured in a soluble dye packet, which will dye up to 2-3 pounds of dry fabric. The washing machine method works well for most colors, however, we recommend the stove top method for darker colors or increased vibrancy. Deep, dark blacks, for instance, are best acheived with the high heat of the stove top method.
The washing machine method can be done in three simple steps. The key to success for all iDye projects is to maintain high temperatures for prolonged periods and to allow enough room for the fabric to move freely in the dye bath.
1. First, gather your materials.
You'll need the item(s) you would like to dye, a packet of iDye Natural, and a cup of non-iodized salt (for cotton, linen, or rayon) or 1/3 cup of white vinegar (for silk). In this case, I am dyeing a pair of white 100% cotton pants, so I needed 1 cup of non-iodized salt, and one packet of iDye. Note: if you haven't already washed the items you are going to dye, be sure to wash them once, prior to dyeing.
*Just for fun, I grabbed some Color Magnet, and stenciled on a small heart on to one of the pockets.
For best results:
Dissolve the packet of iDye in two cups of very hot water before adding it to your machine. Dissolve the salt or vinegar in a quart of hot water as well. This will help maximize your fabric's exposure to the dye within the allotted wash cycle. This will also help prevent any dye from clumping in your washing machine, which may cause mottled results. Pre-wet your garment(s), and avoid pouring the dye and salt/vinegar directly onto the fabric. This will ensure an even application of dye to the garments you are dyeing. If you have a top-loading machine, take advantage of your ability to add the garments to the washer after the washer has filled with water and the dye has been thoroughly dissolved. If you have a front-loader, introduce the dye through the detergent drawer once the tank has filled with water.
2. Set your washer.
Select the hottest setting and the longest wash cycle possible. Ideally your wash cycle will run for at least 50-60 minutes of dye time. You may need to manually extend the wash cycle to achieve this. Every machine is different, check the user manual to be sure.
3. Wash and Dry
The threads are still white! Most commercially made garments are sewn with polyester thread, even if the garment is labeled 100% cotton. Alex's post on blended fabrics will cover this in greater detail.
What about the Color Magnet? If you remember, I stenciled a small heart on one of the pockets using color magnet on to one of the pockets. Flipping to the pocket on the opposite side, you'll see that my heart showed up just great! The area where I stenciled on the Color Magnet attracted more dye, and appears darker.
To help retain the color intensity of your dye, consider washing your garment with iDye Fixative. Once your project is complete, you may wish to run an empty wash cycle in your machine to ensure that all excess dye has been removed. Some may choose to add a cup of bleach to this cycle as well.
