Silkworms were discovered in China and kept as a secret for a long time.
Silk used to be very attractive and also very expensive.
So , scientists started working to find out an alternative to silk
In the process, they found a fibre similar to silk which can be produced using wood pulp. It is called rayon or artificial silk.
Since rayon is made by man, it is called synthetic or man made fibres
Rayon is prepared using wood pulp as a raw material.
And then this pulp is further artificially processed to form Rayon.
That is why it is often called ‘semi synthetic’ i.e synthetic material produced from natural resources
Rayon comes with its own advantages
They are available in various colours.
It is soft, smooth, comfortable and a good absorber of moisture.
They do not allow heat to flow inside, so it can be used in hot and humid weather.
And therefore, rayon is mostly used in clothing industry.
Rayon is mixed with other materials in the textile industry.
Rayon is mixed with cotton to make bedsheets
And it is also mixed with wool to produce carpets
Rayon is similar to other fibres in many aspects
It is chemically identical to cotton but it shines like silk
However rayon has some disadvantages
Manufacturing process of rayon is extremely polluting
Rayon fabric is generally weaker and becomes much weaker when it is wet
Rayon is first obtained from wood pulp
It is soft, smooth, comfortable and highly absorbent
It is mixed with cotton to make bedsheet
Manufacturing process of rayon causes pollution
