The enhancement of the hydrophilicity of synthetic polymers is a
key requirement for many applications ranging from electronics to
functional textile manufacture. Until now, few studies about the
functionalisation of polyamide 6.6 fabrics with enzymes have been
published. This work is a significant step for the replacement of
the chemical functionalisation by the enzymatic one. It is proved
that enzymes, like cutinases or proteases, can be environmentally
friendly tools for the surface hydrolysis of polyamide 6.6. The
bulk properties of the polymers are not affected and the process
can be controlled, in face of chemical methods which are based in
an "all-or-nothing" mechanism. The practical evidences of enzymatic
hydrolysis were achieved by developing specific methodologies,
namely the determination of amines released to the bath treatment
and at the surface of the treated fabrics. Despite the several
difficulties felt through this work, the results represent a
successful prolongation of some works already published in this
area.
