The graph illustrates information about international demand for 4 types of textiles–Polyester, cotton, Cellulosic, Wool– over a 35-year period between 1980 and 2015.
Overall, polyester experienced a dramatic increase in global usage and became dominant by the end of the period. In contrast, there was a slight decrease in market interest for wool, while two fibers (cotton and cellulosic) showed a moderate rise throughout the period.
Polyester and cotton showed much bigger figures compared to other fibers. Starting at just 5
million tons in 1980, the global demand for polyester soared sharply to staggering 69 million tons at the end of the period. Similarly, the international demand for cotton witnessed a noticeable fluctuation from 1980 to 2005, after which it went up to just above 30 million tons in the final year of the period.
By contrast, cellulosic and wool had relatively smaller numbers. The worldwide consumption of cellulosic remained unchanged between 1980 and 2000, and this was followed by a considerable climb to 10 million tons at the end of the period. Likewise, the global demand for wool declined marginally in the given years. Consequently, it became the least popular in the final year.
