The present invention relates to a process for manufacturing a
non-woven article that contains nanofibres and to a non-woven
article containing such fibres. These articles are especially
used in the filtration systems for fluids that contain particles
or in the membrane separation systems used in the textile
industry. These articles are more generally used in the textile
industry. The fibres obtained by electrospinning have a cross
section with a dimension between 5 and 500 nm. The non-woven
articles obtained with such fibres have a high specific surface
area, which favours numerous applications such as, for example,
use as a filter medium, separation membranes and as a component
for the making of protective clothing. Many studies have been
carried out on the conversion of polymers by electrospinning.
Thus, document BR 0313222-6 describes the conditions for the
electrospinning of amorphous, biodegradable polymers containing
a biological agent (such as DNA, peptide, vaccine) for
pharmaceutical applications. Ac
