Aim of the present work was to deepen the knowledge on the effects of funori on cellulose fibers with particular attention paid to their consolidation. Compared to canvas, paper samples (untreated or artificially aged) show different fiber packaging and liquid-absorbing properties.

Surface homogeneity and fiber stiffness observed by us increased over time and the fibers, initially frayed and disordered, were eventually incorporated into the purified funori after several solution additions accompanied also by a progressive occlusion of the pores. The achieved consolidation effect was confirmed by means of mechanical tests.

Electronic microscopy allowed us to evaluate the consolidation and gluing effect obtained through subsequent funori applications.

Abstract

Aim of the present work was to deepen the knowledge on the effects of funori on cellulose fibers with particular attention paid to their consolidation. Compared to canvas, paper samples (untreated or artificially aged) show different fiber packaging and liquid-absorbing properties. Herein, we conducted observations of cellulose fibers by scanning electron microscopy (SEM) in order to evaluate the seaweed extraction method employed in this work, as well the consolidation action had on the fibers through multiple additions of the prepared solutions. Surface homogeneity and fiber stiffness observed by us increased over time and the fibers, initially frayed and disordered, were eventually incorporated into the purified funori after several solution additions accompanied also by a progressive occlusion of the pores. The achieved consolidation effect was confirmed by means of mechanical tests. Moreover, the method herein developed was slightly modified in view of the application of the funori solution to a cultural asset of historical and botanical interest, still scarcely studied. Electronic microscopy allowed us to evaluate the consolidation and gluing effect obtained through subsequent funori applications.
