Graphical presentation of the shrinkage intervals (A1, B1, ΔC, A2, B2) of PUV1 and PUV2 samples highlighting the temperature at which the shrinkage of the first fibre takes place (Tf), the shrinkage temperature (Ts), the temperature at which the last fibre shrinks (Tl) and the total shrinkage interval (ΔT) for the parchment samples exposed to artificial ageing for 748 h. The main shrinkage interval ΔC is highlighted in green
