Description
Small angle neutron scattering (SANS) and dynamic neutron radiography (DNR) investigations have been performed for the non-destructive analysis of different ancient and new textiles.
SANS allowed comparing the nanostructure of ancient and modern linen fabrics, as well as studying the neutron scattering properties of different types of modern wool fibres, providing new data useful to understand the structural basis for their characteristics and progressing technological and material description.
DNR consented studying the hydrogenous liquid migration within new fabric samples, investigating the spontaneous imbibition of single sheets of different textiles. Such experiment proved that DNR is sensitive enough for studies of the kinetics of water migration, determining the dependence of the wetting front motion on time and the changes in spatial water distribution along the fabric. This kind of analysis can contribute to solving problems of conservation and preservation.
The considered neutron characterization has also provided scientific data for further and more comprehensive analyses in the Cultural Heritage field.
