I learned a little more about wool this year and thought I’d share it here:
(All of this probably depends on the way it is spun to some extent, so if any hand-spinners want to correct me, please feel free to. The information below is what I gathered for commercially spun wool.)
There’s been a lot of fuss made in recent years about high micron count wool (very fine wool like merino, lambswool, and cashmere) being “better”. When this fuss is made about it being “better”, I think they just mean “softer” or “thinner”, it does not mean that it is more durable.
I did some research, and generally the thicker the fibre (lower micron count), the more durable it will be, so this year when I needed a new cardigan, rather than just picking the first 100% natural option in my size that fitted my budget (which seems to always be either merino or lambswool), I found a nice Norwegian wool one. British heritage breeds of sheep are also good.
I wonder also if the length of the fibre before it is spun makes a difference? Do the long wool breeds like the Border Leicester make more durable wool than a sheep with shorter wool?
