Fibre staple

The staple of a fibre is the length of the individual fibres.

Most wool is generally between 2 inches (very short) to 4-5 inches (better quality fleece that can be spun very fine).

Fine cottons have a 3 inch staple, whilst linens have a 6-10 inch staple. Linens are also stronger than the cotton for the same reason.

Silk is the longest of all - having one fibre continuously wound around and around to make the coccoon.
