is it wool or acrylic?

#Post

I have some random part balls of yarn which I am hoping to use to do some charity knitting. Apparently wool is the preferred yarn but I'm darned if I can remember which is which. Is there any way to tell the difference?
Thanx in advance - Sue (Mrs L)

Wool is preferred, but I think they will take anything most of the time

If you light it or hold it to the gas, wool um, doesn't burn but acrylic does. I think that's it. Acrylic smells horrible,

I wish all traders would do the burn test before listing their unlabelled yarns...

When a flame is put to a piece of the yarn Acrylics will melt and burn like plastic with dark smoke and chemical smell. Wool will shrivel, smell like burnt hair and much harder to burn.

Wool is usually preferred for small babies as keeps their temperatures more balanced than acrylics.

Another trick I learned is to put a small snippet into pure bleach. If it is 100% wool it will disappear. Acrylics will still be there. If it is a mix the acrylic part will remain but the wool part will disappear, so there may be a slim thread left behind.

Only if you have a match. Not every home has a fireplace, smoker or whatever else you might want to set Light. They may have some bleach though therefore having another option is a great idea.

My nana used to grind a bit of the wool with her teeth and be able to tell what it is!!

Not if you've got Parkinson's disease.

Don't think they should be so picky, as some are for insisting baby knitting should be all wool, but there are those babies and adults too, who cannot have wool against their skin.

There are always purists, especially when it comes to babies. Pity, seeing that kind of attitude takes all the fun out of it...

I admit a bias towards wool for children's clothing as I fell in a fire when I was a child. I ran inside smouldering and was wrapped in a floor rug which extinguished me.

I think I had a very small blister on my wrist.

In which case, use descaled - machine wash - yarn. It is the scales that irritate some skins...

You should be able to tell from the texture what is might be. If it's quite soft, without being hairy, kind of, it probably has a bit of viscose or sometimes silk or cashmere. If it's hairy soft, have a look at the fibers - angora will look, shockingly, like rabbit fur caught up in the spinning process! Otherwise, likely acrylic.

I always burn a bit as well. Wool or a natural fur fiber smolders and smells very strongly of burning hair. Acrylic kind of melt/burns and smells synthetic. Silk is quite hard to burn, it kind of shrinks up and it smells like burned chops! Viscose and cotton burn quickly, with a yellow flame, exactly like a candle wick.

The other option is to see how a piece of the yarn reacts to water. Wool and acrylic will float on top. Cotton, viscose and silk will start to absorb the water. And, of course, wet wool smells quite strongly of wool.

Between all those, you should b able to work out what it's likely to consist of.

I do this but with nailpolish remover. I guesstimate the percentage of acrylic by the amount of fibre left the next day.
Nothing left = 0% up to everything left = 100% acrylic.
