In China, alkaline peroxide mechanical pulping performed with refinerchemical preconditioning (P-RC APMP) is well known to produce fiber with high bulk, opacity, and light scattering coefficient but weak bonding and strength properties. In this study, the characteristics of different P-RC APMP fiber fractions were investigated, and their effects on bonding strength properties were determined. The results showed that there was only 5.8% R30 fiber fraction and 14.1% P100/R200 fiber fraction, and the specific surface area increased from R30 to P100/R200. The tensile index increased by 51.85% and the bonding index increased by 15.35%, when the fibers were changed from the R30 fraction to the P100/R200 fraction. The short fiber fraction (P100/R200 fraction) had smaller fiber length and coarseness but larger specific surface area and greater surface charge density than the long fiber fraction (R30 fraction). The fiber specific surface area and surface charge density made significant contributions to the bonding capacity, whereas fiber coarseness and length were negatively correlated with the tensile index.

Fiber/fiber joints were analyzed using finite element analysis in order to characterize the influence of fiber and contact region properties on the stressstrain behavior of a single fiber/fiber cross. The output of the models was validated by comparison with experimental load-deformation curves. The contact zone of the fiber/fiber joint was studied with respect to the appearance of the contact zone, the contact area, and the contact pattern; the work of adhesion of the contact areas was also considered. It was shown that the two-dimensional appearance of the contact zone had little influence on the stress-strain behavior of the fiber/fiber cross under tensile loading. The maximum stress and hence the fiber/fiber joint strength was, however, affected by the degree of contact. It was concluded that knowledge of the material behavior of the contact zone (such as local plastic behavior), and of chemical effects (such as work of adhesion) are needed to predict the fiber/fiber joint strength.

“…So researchers around the world made good efforts for the preparation of low-cost and high-performance medical dressings. "-" the data not been tested or mentioned bonds seems to be a more likely cause for the increase in breaking force [34,35]. Another reason could be the mixture of alcohol and water, which was a more efficient reaction medium with higher ion concentration around the fiber than that in water, improved the uniformity of reaction in both crystalline and amorphous areas.…”
