Advantages and Disadvantages of Natural
Fibre
Advantages of Natural Fibre
Comfortable: Clothes
made
by
natural
fibres
are
more
comfortable than those made of synthetic fibres.
Environment: Producing materials from natural fibres are less
harmful to our environment.
Non allergic to skin
Disadvantages of Natural Fibre
Expensive: Materials produced by natural fibres are generally
expensive
as
synthetic
fibres
can
be
made
easily
by
manufacturing.
Shrink: Natural fibres might shrink due to aggressive washing.
Unlike manmade fibres, natural fibres are not available in high
tenacity (HT) and medium tenacity (MT).
Natural fibres do not possess a high degree of resiliency as
compared to manmade fibres, hence the fabrics made out of
them do get wrinkles from ‘baggy knees’, possess less crease
recovery.
Production of natural fibres cannot be completely controllable.
Therefore, from year to year quantities of specific qualities vary
and this tends to cause price fluctuations according to variations
in demand which cannot be foreseen until the fibres have been
produced.
Variation in length, fineness, etc. of the natural fibre causes
less regular and uniform yarn than that obtained from manmade
fibres.
The availability of natural fibres is affected by natural calamities
and vagaries of nature.
The production of natural fibres involves the use of land which
is also required for growing the agriproducts. With the
availability of limited amount of land on the surface of the earth,
the demand for land for food and housing on one hand and that
for the growth of natural fibres on the other is to be balanced.
Advantages and Disadvantages of Natural and Manmade Fibres
Advantages and Disadvantages of Synthetic
Fibre
Advantages of Synthetic Fibre
Strong: Synthetic fibres are strong so they can take up heavy
things easily.
Retain their original shape: Synthetic fibres retain their
original shape so it’s easy to wash and wear.
Elastic: Can easily be stretched out.
Soft: Synthetic fibres are generally soft so they are used in
clothing materials.
Colour: Varieties
of
colours
are
available
as
they
are
manufactured.
Cost: Clothes made by synthetic fibres are generally cheaper
than those made by natural fibres.
Specific qualities of fibres can be produced deliberately and
quickly in accordance with the demand.
The filaments can be produced as fine or as coarse as required,
staple lengths can be cut exactly to order. Fibres can be
produced with a high degree of lustre, with reduced or
completely dull lustre, as required.
Unlike natural fibres, the final product of manmade fibres does
not require cleaning.
Most of the fibres are pure white or col tion of the manmade
fibres.
The growth and utility of manmade fibres are mainly influenced
by its positive qualities, viz. wrinkle resistance, crease recovery,
easy care properties, etc. Manmade fibre fabrics bring out
substantial saving on laundry costs; unlike cotton, it can be
washed in a basin in the evening, hung up to dry and be worn
without ironing the following morning.
The light weight characteristic of manmade fibre fabrics gives
more mobility because of less weight and quantity—a tourist can
take along with, him a few clothes. Hence, these fibres are
referred to as Easy-Care fibre fabrics.
Most of the synthetic fibres possess high resistance to moth,
mildew, insects, mould, which simplify the storage problems, the
economy of little loss from these causes.
Disadvantages of Synthetic Fibre
Does not absorb moistures: Synthetic fibres do not absorb
sweat, trapping heat in our body.
Rough feel: Synthetic fibres may give the rough feel, making it
unsuitable for pyjamas, underwear, etc.
Some individuals are often prone to skin allergy, because of the
dermatological action of manmade fibres. This puts a restriction
on its use (such problems do not arise in the case of natural
fibres).
In general, the manmade fibres are generally hydrophobic in
nature; this is necessarily a disadvantage when their products
have to be worn next to the skin.
These fabrics fail to absorb the perspiration; thus the wearer
feels discomfort in a hot climate.
Manmade fibre fabrics are a little difficult to sew. Seams do not
hold tight as in natural fibre fabrics. So, stitching charges were
higher. But this is compensated for by durability and wash and
wear properties.
