Magnetism is one of the properties of substances, the human body has a biological magnetic field, and each cell of the human body is a magnetic microcell. The use of magnetic fields for the treatment of certain diseases, particularly certain chronic diseases, has become a common physical therapy. The magnetic substance and the magnetic field pass through the nerves and the body fluid system of the human body to change the charge, the potential, the molecular structure, the biochemistry and the physiological functions, thereby adjusting the physiological functions of the human body. The health-care function principle of the magnetic fiber and the fabric thereof is as follows: the particle material containing permanent magnets is uniformly arranged in the magnetic fiber, so that N, S-pole magnetic field exists on the surface of the fabric made of the magnetic fiber. The magnetic lines of force generated by these magnetic particles form a magnetic circuit from the N pole to the S pole. The N, S magnetic loops and the emitted magnetic lines generated by the magnetic particles close to the edges of the fabric are interwoven into a layer of invisible three-dimensional magnetic line net. The net can perform omnibearing three-dimensional stimulation and massage on the close skin, so that the skin surface is in a micro-motion state, the cell metabolism capability is activated, and the body microcirculation is promoted. The magnetic particles clinging to the skin acupuncture points can emit magnetic lines of force to penetrate through the acupuncture points. The bundle of magnetic lines is invisible, and the magnetic lines without sensation have the same function as the traditional Chinese medicine acupuncture, so that physical therapy can be performed at any time and any place. This therapy is often referred to as "painless physiotherapy.
Therefore, it is necessary to develop viscose fibers having a function of magnetotherapy.
