how long should i keep yarn on niddy noddy after unraveling a old sweater????????????????? so i can stretch the unraveled yarn back out......................
That will highly depend on a lot of factors such as the fiber content and how tightly knit the yarn was, etc.
If you just tie off the yarn on the niddy noddy in four places evenly around it and then soak it in hot water (with NO agitation at all), you can hang it out to dry and it will probably be pretty kink-free.
HOT water? Some of the softer wools might felt, which makes the yarn harder and scratchier to work with. I've run into that problem with cashmere blends, so I just use room temp water.
But, yeah. Tie it off evenly (I also like to use a different color yarn for easy removal) and, if it's heavier than fingerling, or your hank is bulky, hang about 300 grams of weight from the bottom while it's drying.
I'm so glad other people are deconstructing sweaters. It's been one of the best, most inexpensive ways to get good-quality yarn... and learn something about how commercial sweaters are made. A few years ago I found a cashmere/merino sweater ($15 US) that produced 7 large balls of lace-weight yarn, which I've stranded together to make different weight yarn projects - 3 strand socks, 4-strand gloves, 5-strand cabled hat, and there's more left over. Woot!
Here are a couple of ways to get kinks out:
Once you have it on the niddy noddy, spritz it with water and leave it to dry. If the kinks aren't to bad, that will be enough to take them out. Or...
Take it off the niddy noddy, dip the skein in cold water, and hang it out to dry. If it's heavily kinked, tie a small weight at the the bottom to gently pull the yarn straight.

Think less, enjoy it more.
Getting the yarn wet is key to getting the kinks out. Essentially you're "blocking" the yarn. However, be careful in wrapping the yarn around anything. If is a wool yarn and you wrap it too tightly, and leave it for any length of time, you will be stretching the yarn out.
What the hell is a niddy noddy?
Take a piece of wood, put a cross-piece on one end, and at the other end a crosspiece at 90 degrees from the other. That is one version of a niddy-noddy. Another version would look just like a swift. Used for winding yarn in measured hanks. (the niddy-noddies are usually built so that a complete wind around = 1 unit of measure)

Seeing your question prompts me to introduce you to a Nebraska fiber artist, Robert Hillestad. We are aquainted and I know that he recycles wool sweaters often. He uses a variety of techniques, but he knits a lot. Here is a link to a gallery that represents him: http://www.modernartsmidwest.com/collection/RobertHillestad
Many of his creations that I've seen use the yarn "as is", kinks and all. Here is a link to the gallary at the University of Nebraska named after him: http://textilegallery.unl.edu/
