Analyzing the facts we can see what follows:
We can tell that the success of specific fibers is bound, beside the very good characteristics typical of fiber, to other factors, such as the easiness of the textile transformation and most of all the capacity of answering a real and precise request of the market.
In the last analysis only some of the fibers proposed to the market surpass the first threshold and go by to the real industrial phase.
Even the most important fibers such as para aramidic and carbon ones, that are known and used since a long time, reach still modest quantities.
The importance of the market must consider the prices these fibers are sold at, that are 20-50 times higher than those of the conventional man-made fibers.
The incidence on the entire capacity of chemical fibers is of 0,2-0,3%, that can reach 5-10%.
