A kind of fitness elastic band and preparation method thereof technical field

The invention belongs to the technical field of sports training equipment, and in particular relates to a fitness elastic band and a preparation method thereof.

Background technique

With the improvement of human quality of life and the improvement of living standards, the requirements for environmental health and air quality are getting higher and higher. In addition to meeting the basic living and living requirements, people require our daily necessities and fitness equipment to have more functions that are conducive to cleaning and health and improving the micro-environment, so that they have environmental coordination and health effects.

Negative ions are ions with one or more negative charges, also known as "anions". Negative ions in the air can not only promote the human body to synthesize and store vitamins, strengthen and activate the human body's physiological activities; it also has the functions of killing germs, purifying the air, promoting human metabolism, improving human immunity, enhancing human muscle energy, and regulating the balance of body functions. . Tourmaline (also called tourmaline) is a unique natural negative ion functional mineral material with extremely complex composition and structure. The two end faces of the tourmaline crystal along the longitudinal axis have naturally generated electrical positive and negative polarities, respectively, and have piezoelectric and pyroelectric functions. When heated, compressed or excited by other energy, charges will be generated and released negative ions. technical problem.

At present, there are elastic bands of different specifications on the market, but no elastic bands that release negative ions have been found. At the same time, in the process of use, the elastic band is easily slipped after sweating, and the service life of the elastic band is not long due to the limitation of structure and preparation process.
