Name the feature that determines the quality of wool

Dear Student

There are various features that determined the quality of wool namely fibre diameter, crimp, yield, colour, and staple strength.
Fibre diameter is most important of all. This determines quality and price of wool.

Little more information:

Sheep of the Lohi or Nali breeds produce soft wool that can be used for weaving carpets.
The wool from Marwari sheep is generally coarse and is also used for rough textured woollen carpets.
