  The purpose of this study was to develop a standard methodology for measuring the surface free energy (SFE), and its component parts of bamboo fiber materials.We review the current state of methods to determine the surface tension of natural fibers and discuss the disadvantages of techniques used.Although numerous techniques have been employed to characterize surface tension of natural fibers, it seems that the credibility of results obtained may often be dubious.In this paper, critical surface tension estimates were obtained from CAM measurement.Data were then analyzed by the least-squares method to estimate the components of SFE.SFE were estimated by least squares analysis and also by Schultz method.By using the Fowkes method the polar and disperse fractions of the surface free energy of bamboo fiber materials can be obtained.Strictly speaking this method is based on a combination of the knowledge of Fowkes theory.SFE is desirable when adhesion is required, it avoids some of the limitations of existing studies has been proposed.The calculation steps described in this research are only intended to explain the methods.The results show that the method that only determine SFE as a single parameter may be unable to differentiate adequately between bamboo fiber materials, but it is feasible and very efficient.In order to obtain the maximum performance from the CAM, this measurement should be recommended and kept available for reference.
