Abstract:

By simulating the action of combing hair in daily life and measuring the static voltage on the surface of the standard hair tress, the expression index of the static voltage on the surface of the hair was established. The experimental results show that the maximum static voltage generated when the comb leaves the hair can be used to characterize the static voltage of the hair tress. The static voltage on the hair surface is closely related to the environmental humidity, friction strength, and the damage degree of hair fibers. This method can directly quantify the static voltage on the surface of the hair tress, and is easy to operate, fast, and highly reproducible. It can be used for rapid detection of antistatic products.

Key words: static voltage, expression index, antistatic effect
