The line graph shows the global demand of different types of textile from 1980 to 2015.

The provided line graph below represents the global requirement of four diverse types of materials , namely :

Polyester

,Cotton ,

Cellulosic

and

Wool

between 1980 and 2015. As can be seen from the graph, during

this

period the biggest shift was witnessed in

Polyester

.

It is clear that

from 1980 to 1990 the figures for

this

material rose steadily and

then

fluctuated dramatically until 2000. After these changes , the need for

Polyester

increased steeply and by 2015 , It had reached Its peak (70 million tons). It is

also

worth noting that

Cellulosic

and

Wool

were the sole textiles which had changed differently. Quite as much

Cellulosic

as

Wool

was demanded in 2000 (approximately 5 million tons).

In contrast

,

after

this

period, the data for

Cellulosic

experienced a gradual increase ,

while

Wool

became less popular and had bottomed out at nearly 1 million tons by 2015. It can

therefore

be concluded that from 1980 to 2015 ,

Polyester

was much more relevant than other materials . Meanwhile, the statistics for

Cellulosic

and

Wool

were relatively diverse.
