heating piece of Hankang use nanometer activated carbon fiber technology ,choose activated carbon fiber heat preservation material .The heating sources use high-performance lithium battery serial technology,the products have high scientific and technological content , significant heating effect.Meanwhile,it also has the function of moisture absorption,physical therapy,health care.The products which are the domestic first ,have high additional value,and are bare in market.Live carbon fiber heating piece can produce far infrared ray when heated.Far infrared ray can deep into the skin and subcutaneous tissue,and then promote the blood circulation, make the body keep a certain temperature.Far infrared ray is a kind of electromagnetic wave, can be absorbed quickly by the body.The far infrared ray which is deep in the body,will cause the vibration of the atoms and molecules, and then format thermal reaction through the resonance absorption.The reaction will make the skin temperature rise, promote the blood circulation through the expansion of imperceptible blood-vessel,raise organization and promote the growth of enzymes.Live carbon fiber heating piece of Hankang will have a great effect on clothing,health care and car seat.
