Rit Dye More Synthetic 7oz-Midnight Navy

Used with Rit Colorstay on a 56% cotton 44% polyester fleece heathered grey sweatshirt for a Warden costume. You can see the base color which I left clear on the upper arms. It took really well! Especially considering I did it in a last-minute panic and hadn't realized it would need boiling in a pot that isn't going to be used for food afterward. I put it in a glass pickle jar nestled in my spaghetti pot with a bunch of rags to cushion it and simmered for about half the time it wanted before the jar cracked, very luckily not catastrophically. So the rest of the dye time it hung out in a compromised glass jar below temp and I would absolutely suggest to NOT do that and go to the thrift store for a sacrificial pot instead. :) Regardless of my deviation from the rules, it left a nice muted deep blue-grey. No transfer to other laundry and the color has only mellowed slightly after many washes since.

Doesn't work on bleached stains. But to be fair, they did say it may or may not work. So, if you are buying it for the same reason as I am, don't risk it.

Produit conforme à la description. J'ai pu teindre un vêtement en polyester. En revanche si vous souhaitez une teinte foncée, il conviendra d'utiliser plusieurs flacons

Worked very well, but midnight navy isn't any shade of blue - it's just plain purple. Still worked well for what was intended, since I also like purple, but if you don't, be aware of this!

The instructions on the bottle were tiny, but I watched a few videos before I started. Be prepared! I dyed my white satin/ polyester wedding dress to the midnight blue colour. I had the dress shortened so I used the off cut as a test piece first. Happy with the process I did the dress next and it turned out well. I used 1.5 bottles for the dress and 0.5 on the test piece. I used galvanised stainless steel bucket over a gas stove, and a bamboo stick to stir. Have old towels on hand for around the sink. Even colour coverage. Ended up a bit creased after the heat and spin in the washing machine but nothing a bit of steam won’t fix. I would use dye again now I’ve given it a go, I feel confident doing more.
