• I use procion a lot and I find rinsing the dark colours quite a tedious job. It takes quite a lot of water to get the colour out and sometimes i give up long before the water is clear. Any tips?
  • Have you tried either Synthrapol or Solar Fast Wash? These are both detergents made specifically for dyes. They keep washed out dyes from backstaining(dyes that are rinsing out dying the fabric in areas you don't want them as in silk painting or tie dye). Both of these detergents grab that loose dye and wash it down the drain.

    Washing out dye can be a major chore, but a little synthrapol or Solar Fast wash and what was once a nightmare is pleasure. Maybe not that dramatic, but it is far easier to get the unsecured dye out and down the drain.

    These work really for almost any dye, so I highlye suggest it for anyone, especially if you are rinsing by hand.

    Here are links to check out. It is hard to say which is better. I think that the Solar Fast wash is my personal pick. It just works great. I think you need less too. A capful to a gallon of water and you have some powerful dye removing detergent.
  • Hi there... I also have the same question. I do use synthrapol, but I rinse each item under a faucet first, to get most of the dye out. But I find that for some items, it takes forever just to get most of the dye out under the faucet. Am I being too cautious? I may have 2 items that are reds and oranges and three items that are blues and greens in one load...

    Also a related question... I read that it's best to rinse by hand with cool water, and then wash in the machine with synthrapol and as warm/hot as the fabric can handle, followed by a cool rinse. Can you explain the rationale? Can I give it a quicker hand rinse in warm water (more dye seems to come out with warm) and then wash in synthrapol and warm? Thanks!
  • As long as we are talking about Procion dye, your procedure is fine, liquidkittendesigns. If you use Idye it is better to just use cold water as you can rinse for almost forever if you use hot and you will compromise the final color. With Procion, you can't wash out the dye that has been fixed because it is chemically bonded to the fabric.

    You may be having more trouble with oranges and reds because anything with red in it is more likely to bleed than other colors. This is basically true across dyes, and is the main reason we separate reds from whites when we do laundry.

    I do not personally wash reds and greens together when I can avoid it becuase they are complementary colors and they will dull each other down. When you add red to green it becomes more brown and that deepens the color, but also dulls its brightness. If you are using synthrapol, it should protect your colors, but I prefer to be cautious on that point.

    Procion should rinse pretty cleanly, you may be using too much dye to begin with? If you are constantly washing out dye, you probably have a little too much. You might try cutting back and see if you can achieve the same depth of shade.

    I have been finding that soaking can take a lot of the labor away. You might try several buckets for your different colors and soak in synthrapol for 20-40 min. It should take lot of the rinsing with so much water out of the equation. It will pull the dye out and then you can rinse 2-3 times with clean water and be done.

    As to the rationale behind your cool, hot, cool rinse procedure. The idea is to get a good rinse first, use heat to open the fiber and free the loose unbonded dye, and then to close the fiber back with the cool water to prevent any more dye from coming free.

    You also might try some Solar Fast Wash instead of synthrapol. I think it might be slightly better at getting these dyes out. It is a similar detergent to synthrapol, but I personally prefer it. It is especially good if you want to try my soaking method.
  • Yep - Procion. Depending on the hue, I use anywhere from 2-4 teaspoons per 8oz bottle (black I definitely use 4...maybe a bit more. I have some 5 gal buckets and will try doing a soak first in synthrapol (which I am almost out of and will try Solar Fast next). I'm thinking a quick cool rinse and spin after that, and we'll see where things are. And yep - I've had times where I've separated the complimentary colors just as a precaution. Will definitely do that moving forward, just to make sure. Oh how I wish I had two washing machines and two gas stoves! (I let my wrapped pieces process for 24 hours in the oven, just warm from the pilot light). :)
  • Like Jacquardmod has suggested, Synthrapol or Solar Fast Wash makes the rinsing work much easier. https://kitchenlola.com/
    For me personally, I first rinse the garments in cool water until I see very little color in the rinse water. http://headphonepit.com/
    Then I soak in hot water with about half a teaspoon of Synthrapol per round of fabric. For the whole process I use hands of course.
  • Just want to say rinsing by hand can be very difficult without detergent, especially with Idye. Procion and Acid dyes are usually pretty easy to rinse if you haven't used more than the recommended amount of dye. Idye tends to bleed a lot after dyeing even if you used the right amount. Rinsing in the washing machine works well, but I would not recommend rinsing Idye dyed items by hand without Solar Fast wash or Synthrapol.

    Overly dyed items in both Procion and Acid dye can bleed a lot if they are "crocked" meaning you have used more than dye than the fabric can hold. If you have a situation where the dyed items are bleeding and will not stop, that is usually the issue. This can almost always be solved by using one of the above detergents in hot water from the tap and soaking it for 30min to an hour.
  • Hi there - thanks for all the great rinsing advice. I am about to dye some cotton jersey from Dharma this week - outside and in buckets. I'm on septic and want to minimize the amount of water I'm using for rinsing - the soaking method sounds like it will work great! Question: for the initial cool rinse to remove the slick feeling/ soda ash residue can I swish the fabric around in one bucket or do I need multiple bucket rinses to remove it? I want to conserve water AND avoid running soda ash water down the drain before I can neutralize it with a bit of vinegar. Hope that makes sense and thank you!

    cheers, Frances
  • The soda ash is very soluble. It is going to be rinsed out in the first two rinses or so. 2 in a bucket should do it, and then I think the pH is no problem. Not significant to cause any problems after that.

    Best thing to reduce rinsing is to make sure you aren't using too much dye. Black can be hard to avoid as it takes more color to make it really black.

  • Thanks so much for the additional rinsing scoop - I'll go forward with confidence and use a light(er) hand on my dye powder/solution for the first try.
  • Is the rinsing you suggest also truefor idyepoly? I don’t rinse til cooled and even overnight. So there is excess dye but it rinses clear pretty quickly. Red and pink take the longest.
  • Yes, the poly dye also rinses easier if you use the right amount for the fabric. It is difficult to avoid if you are looking for dark colors. However, if you are looking for a med shade, it will rinse better if you dye longer with less dye than if you dye it shorter with more dye.

    This is called "exhaustion" of the dye. Some dyes exhaust better than others. Acid dyes are usually the best at this. They are really attracted to the silk or wool and can take the dye completely out of the water so the water is clear at the end of dyeing. Poly dyes can also be mostly taken up by the fabric, so if you use the exact right amount, you will not have much rinsing to do. The more you dye, and the more you are familiar with the fabric, the better you can get at estimating this. It does vary from color to color too.
  • I have a customer who has complained about my velvet bleeding especially the red.
    You have said in the past that there is no mordant for the dye and poly. So I cool the fabric down and rinse in cold water til clear. The red takes the longest time to rinse clear. Any tips on hastening that?
    And once the velvet is set and doesn’t bleed dye will it not bleed in warm or hot water?
  • An addendum as the customer has sent pix. These were allreds. She says after cold water rinse has rinsed clear, the velvet will bleed quite a bit if warm water introduced. Have refunded her order but need to determine cause. Have you changed your red dyes at all recently?
