| Product: Coco / Bristle Fibre |
|
 |
|
| Origin: Sri Lanka |
|
| Description: The main source
of supply for coco or bristle
fibre is Sri Lanka, where
it is obtained from the fibrous husk of the coconut.
Bristle fibre can be dyed black, polished and flagged to
resemble hog bristle. It can also be bleached. |
|
| Uses: In the brush industry since it is strong, light, elastic and has a good water resistance. It is often mixed with other stiffer materials, usually Mexican fibre, for the production of brooms and brushes. |

Production Details: The
coconut husks are separated from the nuts
by striking them on a sharp iron spike. The husks are
then soaked for between 3 and 6 weeks in pits where bacterial
action facilitates separation of the fibres by partially
disintegrating the pith, which acts as a binding agent.
The fibre is extracted in a process called "wet milling";
using a drum with embedded nails revolving at between
150 to 250 rpm, the operator feeds the softened husks into the
machine to about half their length and as the drum
rotates, it beats and combs each husk so that the longer
fibres are left in the operator's hand and the shorter
fibres and extraneous matter fall to the floor.
The fibre is sold in three main qualities. Average
quality fibre is tied with a single cord of fibre and
is known as "one-tie", and receives no
further treatment after initial production, except for
bleaching. The better quality fibre is hackled, or
combed, by drawing the fibre through steel combs, which
further removes the shorter fibres and other matter.
These removed short fibres are referred to as Omat. The
longest and best quality hanks of fibre, about 30cm in
length, are
known as "three-tie", while the next grade of
shorter fibre is bound with two cords and is known as
"two-tie".
According to requirements, the fibre can be bleached to
give it an even, golden colour or dyed (usually black).
Further processing can include cutting the ends of the
bundles of fibre to obtain a uniform length.
