Fibers are highly adaptable
This does not make sense. What does it mean?
Student or Learner
Cashmere is characterized by its fine, soft fibers. It provides a natural light-weight insulation without bulk. Fibers are highly adaptable and easily spun into yarns and light to heavy-weight fabrics. The original undyed or natural colors of cashmere wool are various shades of grey, brown and white.
It is my opinion that "original undyed or natural colors" is redundant, and I would choose only one, as in "The natural colors of cashmere wool are ...".
You also have strangely and incorreclty hyperlinked several words in your post. Feel free to send me a private message and I can help.
(to OP) but to make it clearer you could start the sentence with 'Its'.
Also, some people might have a problem with 'light to heavy-weight fabrics' (because it means 'light-weight to heavy-weight" => "light- to heavy-weight"). But other people feel equally hostile to this sort of 'hanging hyphen'. You could pander to both groups by saying 'fabrics with weights ranging from light to heavy', or you could just stick with it as it is and tell them to get a life.
PS The hyperlinks are ours. There's an icon that lets you remove them - but I've never got it to work.)
The context is from the item "cashmere" from wikipedia. If only links are allowed here, you'll know why.
