Abstract: The effect of chitosan (CS),fibroin (SS) and chitosan-fibroin on the physical properties of recycled paper (RP) was studied.According to mechanical properties of blend system,the interaction force of RP/CS/SS reached the maximum at the load of 6% and mass ratio of 4∶6,and the tensile index,tear index and folding endurance of RP/CS/SS blend also got the maximum.Moreover,the addition of SS largely improved the softness of RP.The analysis of SEM measurement showed that the faction of CS/SS was homogeneously distributed over the fiber organization of RP by the interaction among CS,RP and SS.The accumulation of incompatible component was not observed on the blend process,and the density of RP/CS/SS was relatively reinforced.
