Stress and strain curves (a) obtained at 20% RH (25 °C) for the degraded cotton canvas (warp direction) before and after treatment using the newly developed CNF consolidant and 2 adhesives commonly used in conservation, animal glue and Beva® 371. The Young’s moduli calculated from the region of interest (i.e. 1–2% in elongation) are given in the table in (b). The star marks a sudden loss in canvas stiffness measured for the CNF-treated sample only
