(Right) Hemp fibres are from the stem of the hemp plant. The fibres are extracted by crushing and drying the stems, followed by shaking, which separates the woody part of the stem from
the cellulose fibres. Fibres up
to almost 2 metres long can be obtained. Each fibre is a single long cell, which is naturally dark brown. It cannot be bleached and so is used as a rough,
strong fibre. It is used
for sacking (burlap),
canvas, twine, and
similar purposes.
(Above and below) Coir is a fibre made from coconut husks.
The husks are kept and dried. They are then buried in mud flats until the matrix has rotted away and left only the tough fibres. They can then
be used to make hard-wearing materials such as doormats.
