Abstract:Compared with traditional handmade paper， modern machine-made paper in Chinese collections exhibits severe brittleness， yellowing， and loss of mechanical strength. These deterioration phenomena are closely related to the lignin residue from the pulping process. To gain a deeper understanding of the deterioration mechanism of modern machine-made paper， this paper reviewed the early production technologies and the evolution of pulping and bleaching processes. It focused on the structure of lignin and its mechanism in causing paper deterioration， specifically analyzing the impact of lignin on the physical strength and chemical degradation of paper. Furthermore， it elaborated on the process by which， under environmental influences such as chemical reagents， temperature， humidity， and light， the oxidative degradation of lignin produces chromophores and acidic groups. These derived groups then initiate a new round of acidification and autoxidation， resulting in the progressive deterioration and yellowing of the paper.
