Mercerisation is now also being done to wool fibre.

Micron (wool), is the measurement used to express the diameter of a wool fibre.

At first, only wool fibres were used.

The steam swelled the wool fibres, and after a thorough vacuuming nobody was ever going to know a heavy piece of furniture had once rested there.

It tends to work well with wool fibres because their scales, when aggravated, readily bond together.

If made using the wet method, an artificial felt will contain a minimum of 30% wool fibres with the rest being artificial fibres.

Staple - a group of wool fibres that formed a cluster or lock.

A micron (micrometre) is the measurement used to express the diameter of a wool fibre.

A Wool Staple is a naturally formed cluster or lock of wool fibres and not a single fibre.

The cluster of wool fibres is made by a cluster of follicles.
