Wool often has a distinct smell when wet. Try getting a bit wet and
sniffing.

Subject: [h-cost] Non destructive testing for wool/synthetic

Hi everyone,
This is not directly historical but I knew this list would be my best chance
of an answer.
My uncle sent my 2 month old son a gift of a hand knitted cardigan which he
bought from a charity stall. without a label I have no way to know if they
have used wool or acrylic yarn.
I know I can test using bleach or a burn test but I don't want to damage the
garment is there a non destructive test I can do on a finished garment?
Thanks
Elizabeth

Super fast way: wool is a natural fibre and has scales. So this means that
like human hair you have a smooth direction and a not smooth direction.

If you take a lock of hair, hold it tight you can easily run another finger
down the length but it catches on the way up.

Wool I think is less scaly, but acrylic is not scaly at all. So if you can
get a few loose threads you could feel for that. Same reason woollens fluff
up but worsteds are smooth. In worsted the fibres are spun in one direction
in woollens they are in both directions so the fibres catch with the scales
more readily.

This will really only identify natural vs spun plastic though :)

But wool also smells of wool when washed, and I find acrylic squeaks
upleasantly when rolled between the fingers. My school uniforms used
acrylic for the bulk of the fibres and this was the sensation I most
recognise.

A really good microscope would definitely identify the fibres :)
