3. Types of fibres
 Natural fibres come
from natural sources
like plants and animals.
Cotton, linen, hemp,
jute, flax, rhea, silk
cotton (simbal) coir and
others come from
plants. Wool and silk
are common fibres
obtained from animals.
 Synthetic fibres are
man-made fibres.
Synthetic fibres are
made from different
chemicals, hence each
kind of synthetic fibres
have their own
properties. Synthetic
fibres are more in length
and are long lasting. The
only limitation in
synthetic fibres is that
they are poor
absorbents of moisture
and they catch fire
easily.

4. Monomers And Polymers
Substances are made of units. A substance having
a single unit structure forming its particles
called a monomer (mono or monos means single;
mer means unit). In certain substances
thousands of units join together to form a large
unit, called polymer (poly or polus means many).
Polymer is made of many repeating units.
The process of joining together monomers to
form a polymer is called polymerization.
Monomers may combine in two different ways
to form a polymers:
