Fibres
From the Old Stone Age, man knew the use of fibres for making various articles of daily life.
Samples of flax found in the lake dwellings of Switzerland, linen from Egyptian tombs, and
Cotton fibre from Mohenjo-Daro attest to this.
Fibres go into the making of cloth,
ropes, cords, brushes and mats. Coconut, palmyra, jute, cotton, pineapple, agave are some of
the plants that yield fibre.
Fibres known at present are many and
varied and are classified in many ways depending on the use to which they are put.

Jute stem
'Jute' is the best of the
coarser bast fibres and one of the most important commercial fibre crops of the world,
particularly in India. The fibre is obtained from the stems (secondary phloem) of the genus
chorchorus, which belongs to the family 'Tiliaceae'. The plant is a slender annual. It is tall
and attains a height of 10'. It bears alternate simple leaves. The jute fibres are used for
bags; the poorer fabrics are used in the making of gunny bags while better ones are used for
the manufacture of twine upholstery rugs, carpets etc.
1. Corchorus olitorius
White Jute
The most important commercial fibre
is extracted from this plant which is called as 'Jute'. This plant belongs to the family
'Tiliaceae'. In the Flora of British India, it is stated that this species is indigenous in
many parts of India and is generally distributed by cultivation in all tropical countries. It
grows and cannot thrive under water logged conditions. The plant is a slender annual. It is
quite tall and attains a height of 10'. Stem may be branched near the tip. It bears alternate
simple leaves with small groups of two or three yellowish coloured flowers; the fruits are
long cylindrical capsules.
2. Corchorus capsularis
Jews Mallow
This plant is believed to be native
of South China where it is found in the wild state. The plant might have entered India from
there. This species accounts for nearly 75% of the total acreage under jute cultivation
because of its ability to grow on both high and low lands and in water logged condition. In
this species it is more adaptable particularly to flooded condition.

Ananas sativus
Pine Apple
This is a very familiar tropical fruit
plant belonging to the family 'Bromeliaceae'. It furnishes fibres of great strength and fine
quality. They are white, shiny, very durable, flexible and are not injured by water. The
plants are cultivated for fibre, and are planted close to each other. The fibres are collected
from the leaves. Usually leaves are cut after two years and the leaves are scraped out by
hand, dried and combed out. The fibres are tied end to end and can be woven. In Philippines
Islands the 'pina cloth', is the most delicate and highly prized fabric. In Taiwan, the fibre
is used in making stronger fabrics.

Pandanus
odoratissimus
Screwpine
It is a fibre yielding plant,
belonging to the family 'Pandanaceae'. It is an Angiosperm member. The plant grows to
perfection in the warm, moist climate and in swampy soil. A common much branched shrub,
frequently planted on account of the powerful fragrance of its flower.
The plant yields plaiting fibre obtained from the leaves and roots. The leaves
are cut every second year, which yields sufficient fibre to make large bags. The leaves are
composed of tough, longitudinal white glossy fibres which are employed for covering huts,
making mats, for cordage and for fishing nets
The root fibres are used by basket-makers
for binding, when cut into lengths and beaten out; they are commonly used as brushes for
painting and whitewashing.
