JacquardiDye Fabric Dye-Violet (For Polyester)

It did the job and did it well--but had to dye the dress twice. Also, my dress was 50% natural fiber and 50% poly, so I used one packet of 'idye poly' and one packet of 'idye for natural fabrics' both in violet as per Jacquard's online instructions. So, in total, two dye jobs with 2 packets=4 packets of dye for one size large dress. An investment and much more dye than I thought I would need for a single dress, but worth it to get the color right. And I am very very happy with the final result.I was not looking for a tie-dye look--I wanted a solid professional-looking color to transform my off-white semi-formal dress. This may be user error on my part--either I didn't leave it in long enough or else the dress was so heavy that it just needed more packages of dye to really saturate the fabric (the package does say for 2-3 lbs of fabric only). While my dress was definitely under that weight limit, it was long-sleeve and floor-length with a slip, so it was a rather large volume of fabric though not weighty, so you kind of have to take the weight limit as a guide, not an absolute. The first time I dyed the dress it came out very mottled and uneven--very tie-dyed look. The second time did the trick--a perfect even DEEP and RICH purple color, very professional and exactly the hue I was looking for. Both times I let the dye soak in at a very low simmer on the stove (not boiling, but hot to the touch) for about 45 minutes.I dyed the dress in a large pot on the stove--trust me when I say make sure you wear heavy rubber gloves and have lots of paper towels on hand when working with this dye--it will get everywhere and stain your hands in an instant. Also make sure to have a couple of cups of non-iodized salt on hand, which is needed as per the instructions.

Did the job I needed it to for a cosplay accessory.

This worked great. I will buy this brand again. I've only ever used Rit before but in the future I will use this. I made a huge pot of dye mix and boiled it on the stove. I put it aside because it was so much and only had to dye a dress, a bra and a purse. It felt wasteful dumping it out so about a week later I used it to dye 3 shirts for my daughter then since I still had it dyed some tea towels. I didn't intend on doing this but I kinda forgot about but the crazy thing is after sitting so long already mixed it still worked perfectly. Oh and I only used about half the packette.

I LOVE Idye products, but this is the first time I used the poly dye. Didn’t stick to the items I wanted to dye. It just rinsed right out. Been doing cloth dying for years and I did the research, so I did follow the directions. The dye just didn’t take.I’ll stick to the natural fiber dye.

Technically, this should be a negative review. I purchased the violet and crimson packs, mixed them, and proceeded to attempt darkening a gorgeous dress that was ruby red. Dress was 100% polyester, but that was all the information I had. 3 hours and a huge mess later (rinsing took forever; dress was like a gown), the dress was exactly the same shade as when I started. At least I didn't mess the dress up. Not a hint of the dye stuck to the dress. It was incredible.However, for fun, I threw in a peach bra that I never liked because, well, it was pastel peach. It came out, in 20 minutes, a beautiful purple. I love it. Threads didn't dye, but that's fine. Looks like something out of the Victoria's Secret Pink collection.Prior to dyeing, I made sure to do a ton of research. Hours of reading websites and reviews. I washed the dress, kept it wet before dyeing, purchased a huge pot exclusively for dyeing, even purchased barbeque gloves. The people at Dharma Trading are awesome for answering questions about dyeing anything, and the BBQ gloves were recommended so I could really reach down to the bottom of the pot to move the dress, not just stir it. Apparently, the bottom of the pot, being hottest, is where the dye takes best, so it's important to get down there with the gloves and make sure not one part of the dress hangs out there longer than the others.Of course, none of that mattered in the end. When I called Dharma Trading again to see if I should attempt dyeing longer, I was told no. Most polyester materials work wonderfully with this dye, even straight up plastic (I've heard), but some materials have been chemically treated and will resist. Including this ruby dress. Oh well. There's no way of knowing until you try, said the Dharma rep. I'm not even mad. Even though my dress didn't take, the rich color my bra acquired was enough to convince me to try again with idye-poly next time I need it.One more thing: some reviews said the dye will dot your kitchen with color everywhere. This is true. I was extra careful opening the package, made sure not to let my hot water boil, and covered all the area around the stove with foil and fabric on the floor. My Freaking window sill had some purple. The counter on the opposite side of the kitchen from the stove had purple dots. I don't know how, but but this stuff just gets into the air and travels. I'm in an apartment, so there's nothing I can do. But if you have a hot plate and a balcony/backyard/etc do yourself a favor and take this outside.

In this case, I was so hesitant to buy because the product name stated “iDye for Polyester” - which should actually be called iDye Poly.The photos also showed the regular natural fiber dye iDye.So I held my breath when I clicked Buy Now. But very happy to report the item I got was iDye Poly! Hurray!

Super rich and deep purple color. Used the stove top method to dye a small stuffed animal, it acquired the deepest color in only a few minutes. I continued to stir it in the dye bath for the full 20 minutes recommended for deepest color but after dyeing a few more that were dyed for only a few minutes I found the full time unnecessary.stuffed animals rinsed with water running clear in only a minute. (if one were dyeing large stuffed items it would probably take longer depending on how the stuffing takes the dye)One suggestion if dyeing items that have accessories glued to them - try to remove the accessories to re-glue on later, the heat of the dye bath might melt the glue and you'll be desperately straining the dye bath for tiny bunny tails...
