Abstract: People pay more attention to the health care function on the human body of the magnetic fabric, The surface of magnetic fabric plays function of health care through the Acupoints. This paper discussed the methods of measurement and the description of the results. The magnetic flux density on the surface of magnetic fabric sample was measured by use the special instrument of high-precision Tesla measurement, and the distribution of the magnetic flux density on the surface of magnetic fabric was presented by the methods of information virtualization. The experiment have been conducted on washing and chafing to research the varying characteristics of The magnetic flux density on the surface of magnetic fabric sample. The results of our experiments shows that The magnetic flux density on the surface of magnetic fabric trends to increase firstly in the beginning of washing experiment and then decrease after three times of washing. Generally, fabric loses magnetic after washing 15 times or so. One of the key factor influencing the durability of The magnetic flux density on the surface of magnetic fabric is the content of magnetic fiber in magnetic fabric.

Key words: magnetic fabric, magnetic flux density on surface, washing, durability
