Brown for Natural Fabrics Polyester and Nylon 14gm Fabric Dye-iDye (Jacquard)

This is very good dye. It's easy to use and doesn't stain anything except what you're dying. Apparently doesn't bleed, either. Using this was a much more pleasant experience than my last attempt at dying something with RIT.That said, I was trying to dye some ugly light green cotton/poly curtains a darker, prettier shade, and while they look much better now, they didn't turn out exactly the way I wanted. But that was probably on me, not the dye.Because I didn't have a big enough pot for the stovetop method, I used a front-loading washer. It says on the Jacquard website that you can do this, but my experience is that it's not recommended, at least not with big items like curtains. Supposedly the amount of dye was appropriate for two 84" panels, but I don't think there was enough water in the washer. Also, it was impossible to keep the water as hot as it should be. I have my hot water heater turned up all the way and also threw at least 8 quarts of boiling water into the washer, but it needs to be that hot for at least 1/2 hour of agitation and I don't think it was. Perhaps if my item had been smaller so it moved more freely in the water, the temp wouldn't have mattered so much. But whatever, I think my curtains would have been darker if I'd had more water and/or hotter water. Darker is what I wanted.It also didn't smell nearly as bad as some reviewers indicated. There *is* an odor, and I think it gave me a mild episodic headache, but it's not anywhere near overwhelming as long as you have your windows open and a decent cross breeze. Perhaps the really negative reviews about the odor were from people who couldn't or didn't open their windows, or maybe who have severe chemical sensitivities. In the past the odor might have bothered me a lot, but since I've improved my health my sensitivity to odors has remarkably diminished. So I didn't find it troublesome.I was very happy to find that there was no green residue left in my washer. I washed some old green and blue things (stuff that no longer bleeds) right after I got done with the curtains, and also threw a snow-white rag in there to see if there was any staining or residual dye left in the machine. Not a bit.So I consider this product a win.What I'm going to do is get a bigger pot and two packets of dye and try again, stovetop, following the directions precisely, doing only one curtain panel at a time. I liked this product enough to try again.My main quibble doesn't have to do with the product itself but with the Amazon listing. In Amazon product description it says for "100% natural fabrics", but then the picture of the product is of iDye Poly, which is only for synthetic fabrics or blends. I asked the seller a question on Amazon, which went unanswered. Decided to buy anyway, and what I actually received was iDye Poly, which would not have worked if I'd had 100% natural fabric like cotton or silk.But for synthetic fabrics and blends, highly recommended!

Wear gloves make sure you boil this & stir. worked great for my light weight pjs that were a yellow beige & I dyed them BLACK!!!!! It worked well. I tried rit dye but their darkest color is charcoal & it turned out splotchy even tho I heated it all night. . I redid it using the same water/dye mix & added three packs of this product. It dyed two sets of ugly light color poly pjs & I will try to brighten up another pair of faded black lightweight poly pjs. Saves $$$$ & it’s kind of fun. Washed in cool water & they look BLACK. yay! 3 sets of pjs that I will actually wear now.

if i could give this product 0 stars i would.this was not my first time using a dye like this, but it was my first time with this brand and i will never use it again.i followed the simple directions perfectly and my supposed to be pink fabric came out purple and very splotchy. my fabric was white to begin with and i only left it soaking for 45 minutes.that really isn’t my biggest concern though. the SMELL was absolutely the worst part. the other reviews on are are not exaggerating at all. i am usually not bad when it comes to strong odors, but i think i may have had an extreme sensitivity to this one. although i was in a well ventilated room with windows open and fans on, almost instantly after the steam started i got a terrible migraine and felt extremely light headed. i tried getting fresh air outside and drinking water and taking medicine to try and calm it down but it would not go away. i needed my boyfriend to finish the soaking process and clean up for me because i could not be in the room any longer. i’m not trying to sound dramatic but it really was horrible. i even ended up vomiting several time. it is about three hours later now and i am still feeling very dizzy and nauseous while writing this.i’m sure this isn’t common for most buyers because not a whole lot of reviews say it was this bad for them, but just be extra extra careful when using this product, and i defiantly would not purchase it if you have even the slightest sensitivity to this type of stuff. i will NOT be purchasing this again.

I've used this type of dye before (though the natural fiber version) and had great success using it in my washing machine, and hoped to have a similar experience with dying some polyester items. I had a bit of unanticipated user error and a lot of the dye had settled at the bottom of the pot I was using, and despite stirring regularly, the items I dyed have splotches and from uneven dye distribution, I'm guessing from what had settled to the bottom of the pan. I had a similar issue with the cotton version and realized for subsequent dye batches that I needed to thoroughly dissolve the dye packet in another container (I used a glass jar and shook the dye in a small amount of hot water until I couldn't see strands of undissolved plastic) and had better success. I didn't think to do that with this packet but I will in the future when I re-dye these sweaters to try to fix the splotches.Great color and very easy to use, just watch out that the dye is evenly dispersed/diluted before adding your items to it, since it's difficult to see what's going on until it's too late!Also I was pleasantly surprised that the grey buttons on my sweater collected dye as well and are now almost black - they look great but I hadn't anticipated that the color would change too.

Really great dye, I had a 100% polyester dress that turned out beautifully. I did make sure to prep the dress and have a big enough tub that it could move freely in
