Frictional Behavior of Different Glove Materials Sliding Against Glass Sheet
M.M. Mahmoud

Abstract:
Objective: Robots are involved extensively for materials handling in many industrial applications, where friction is important for the safety of materials handling. This present study aims to discuss the frictional behavior of glove materials sliding against glass sheet at various contact conditions. Methodology: An experimental program is designed for testing different glove materials sliding against glass sheet. Where, eight different glove materials were selected and tested to measure the coefficient of friction at dry, water wetted and oily conditions using test rig that constructed and manufactured for this purpose. Results: It was found that at dry sliding, the glove materials of the highest friction coefficient were latex, synthetic rubber, wool, nylon, cotton, natural rubber I, natural rubber II and polyester. At water wetted sliding, the highest friction values were displayed by natural rubber II, natural rubber I, cotton, synthetic rubber, wool, polyester, latex and nylon. At oily sliding, the ranking of the tested gloves were natural rubber I, natural rubber II, nylon, wool, cotton, synthetic rubber, polyester and latex. The drastic friction decrease observed at oil sliding of latex endangered the materials handling, therefore, it was recommended to avoid such types of gloves at oily applications. The values of friction coefficients under polyester at the three sliding conditions were too low to be safely used in applications. Conclusion: Glove materials were classified and ranked based on the measured coefficient of friction. This highlights the dependency of glove materials selection on the contact conditions to fulfill grip requirements and working conditions for efficient handling and mobility performance.

Hi, I want know the coefficient of static and dynamic friction between nylon and latex.
