This study explored the reinforcement effects of bacterial cellulose on fragile paper.The organic system reinforcement solution us-ing bacterial cellulose as reinforcement material and DMSO as solvent,which could effectively improve the mechanical properties of paper samples.When the bacterial cellulose dosage was 10%(relative to paper dry mass),the tensile index was 54.7 N·m/g,increased by 50%,and the folding endurance was 1.57,increased by 76%,with little impact on properties such as thickness,density,color difference value,and whiteness.Paper opacity was 95%,and capillary rise was 2 mm.After 7 days of dry heat aging,the tensile index was 46.0 N·m/g,the folding endurance was 1.38,and its mechanical properties were higher than blank paper.The reinforced paper exhibited good durability,did not experience wrinkles or deformation,and the drying process was simple.
