Jacquard Acid Dye 8oz Jar Jet Black - Acid Dye for Wool, Silk, Alpaca, Feathers, Cosplay Wigs and Nylon - Powder Wool Dye for Full Coverage Dyeing - Vibrant Acid Silk Dye

Amazing product. Wonderful rich color! I dyed a cashmere sweater according to directions and it worked beautifully.

I don't have experience in dyeing, but I followed the instructions as exactly as I could in dyeing a 40-year-old cream-colored aran with a few small stains. I had a large canning pot (an even larger one would've been better but I'm not sure they're made any larger), and I was careful about gradual heating and cooling. It was in adding the vinegar that the true color popped out -- a rich brown, just what I wanted. However, I think that this sweater had "background" discoloration that I didn't see, or perhaps something else going on, as the dye took unevenly, and there are darker brown and redder sections in places. The sweater was large, so maybe the pot was too small (sweater weighed 1.15 lbs dry) and didn't allow for enough stirring, but I sure made an attempt at it (even while being careful not to over-agitate). As I washed it afterward in Synthrapol to remove extra dye, I read on the label that one could add it to the dyepot to encourage even uptake -- wish I'd read that first. I see that another reviewer has mentioned soda ash or urea, and one of those might also have helped. So I don't know whether the issue was not enough stirring or background discoloration in the wool that led to uneven take-up, but the end product isn't great. I can and will wear it at home but probably not to the office. These issues aren't the fault of the product but rather of my inexperience and/or the item I was dyeing. The product was fine, the color a really nice true-brown. So: do as much prep as you can. This activity took several hours (not at all once), so allow for that as well. I'm uploading a picture but it doesn't do the brown justice -- a brown like a dried oak leaf, or tobacco and there are also shadows across it.

This worked wonderfully on my father-in-law's old wool slacks. The color was rich. I'm very happy with this product.

Great dye for a white Good American swimsuit. Followed directions and within 30 minutes, it was a very deep, dark black. Let it soak longer. No fading as of yet. Highly recommend. Would purchase this brand/type again and definitely in other colors.

Worked like a charm! Dyed a blah sweater teal- gorgeous!

If you want an electric pink on steroids--this is it! I love it. It's the color of a pink highlighter. I don't know if it actually fluoresces, but it's bright. It's exactly the shade I wanted to dye wool with. However. I dyed some raw farm wool last night with this. The pH was 4 and the dye pot was held at just under a simmer for over an hour and the dye did not exhaust. I let it cool completely in the pot overnight. And today, when rinsing, there was a lot of bleeding. Now, the wool is not oversaturated because I used this dye very dilute. I wasn't going for a deep dark pink--I was going for a very light color. So I'm worried about fading for two reasons: 1) it's fluorescent which means it's fugitive (fades quickly with time, exposure to sunlight etc) and 2) The dye bath did not exhaust and the dye is running during rinsing which means it may run every time I wash this wool. So. This is quite the dilemna. I'm contemplating overdying it with a different brand in a ho-hum magenta just so I can be sure that it will actually stay pink. I'm not sure I want to mess with this anymore because dying wool is such a big production. BUT. Despite manufacturers stating that acid dyes need a pH of 4.5 to effectively strike, some dyes seem to need a much lower pH to fully take up. pH is on a logarithmic scale--so 4 should have done the trick, but I'll try going a bit lower to see what happens with this. One more chance Jacquard. I'll report back later if I come to any distinct conclusions about this. Every dye is different. I wish the manufacturers would give us all the info on each individual dyes quirks so we can make informed decisions instead of having to find out on our own after paying for the dye. Harumph.

I could have spared myself 2 hours of effort and just used a lighter to burn up $34 in cash. This product DOESN’T work. I bought the 8 oz. package; the label (which isn’t fully picture on the listing) says the contents should be enough to dye 2 lbs of fabric. For reference, the wool poncho sweater I tried to dye weighed only 1.5 lbs. I followed the directions exactly and was excited to see the sweater immediately take on the rich blue color. After standing and stirring it for 40 minutes - and then leaving it in the dye an extra 4 hours just to make sure it would take - I went to rinse it and ALL the color washed right off. (Bear in mind this was a cream sweater. After the rinse, it is still currently cream. Zero color difference.) Where the dye *did* stain was my hands and fingernails once I removed the sweater from the pot. I used some heavy nail polish remover and my hands are still blue. I hated this product; from the reviews it looks like sometimes it works? For me, I rinsed $34 down the drain.

Works like it should, when I eventually got the right product

Brilliant just what I needed

I managed to repair an apple green dress dyed with Dylon violet - ending up being stool brown with this amazing product. I highly recomand it! Was like a miracle to make a nice colour again. I dyed wool so I didn't used hot water as they advice but I still got very good result.

You can't go wrong with Jacquard acid dyes when dyeing animal fibre. The colour is reliable and fast ones set with citric acid or vinegar. A terrible shame the whole range of colours aren't available more widely from a UK seller.

Sieht nach Kürbis aus. Ein klein bisschen matter als erwartet. Das Material ist naturfarbener Kaschmir. Verwendet habe ich fast die ganze Packung.

I bought this to dye nylon cord as it said it's for nylon. Didn't work. Might be better on cloths.
