I have a bird that loves red cabbage. But she only eats a few ounces off a head. Thats a waste of 2 to 3 lbs cabbage every week or so! I am going to try using the cabbage for dye.
I read that cabbage dyes react differently to how acidic the water is. Obviously this means one can vary the ph of the water for different colors.

I am facinated by this and was wondering if anyone here has any first hand experience. What additive did you use and what color did you obtain?

Well, I Googled and came up with the following images. Each image mentions the natural dyestuff and the additive. Not sure if it is any help, but it is kind of interesting to look at:

Cabbage "juice" can be used as a pH indicator. It should be purplish-red as a neutral solution. If you add acid to it (vinegar, lemon juice) then it will turn red (how red depends on how acid). If you mix it with something basic (baking soda, ammonia) it will turn greeny.

I did a fun arts and crafts project where I soaked sheets of paper in cabbage solution and then let the kids "paint" with lemon juice and a baking soda solution.

This could be a really fun experiment to do for hand painting yarn. If you soaked the hank in the neutral solution you could change colors on part of the yarn by painting it with different pH solutions. What could you do to make it stay that way?

Cheers,

Charc

Yes, but how permanent would a cabbage dye be, what with washing and wearing and sweating and all? Even if one washed carefully with gentle soap, some dye will invariably wash away rather quickly I should think. Not a problem if your project is going under glass and protected from exposure to sunlight. Even if you just use it for a handbag, the sweat and oils on one's hands might interact unfavorably.

That's the inherent problem with natural dyes...

I havent actually used my cabbage dyed yarn for anything. I was a bit disapointed with the color. It came out about the color of bandaids - but the stretchy cloth kind, not the plastic kind.
It is not really ugly - just not what I wanted. If I were feeling kind I might say it is "shell pink" or more poetically, "sugar tan". And then there is the spinning. lol This is seriously overspun stuff.
I have not done any testing of wash or light fastness.
But it could still be a useful dye for tapestry and other items that do not get a lot of handling.

charc - you got me thinking about that yarn. I pulled it out and tested it, I wasnt sure if the color would be affected by acidity or not. I am happy to say that at full strength vinegar did not affect the color. I am letting a sample sit with the vinegar on it for a while. Several hours. We shall see if there are changes later :D
