Nano-negative ion finishing agent is a functional additive used in the finishing process of pure cotton, polyester-cotton, synthetic fiber and other fabrics. Fabrics treated with nano-negative ion finishing agent have a significant effect of being stimulated to generate negative ions. 1. Effect on the nervous system: It can strengthen the cerebral cortex function and mental activity, invigorate the spirit, improve work efficiency, and improve sleep quality. Negative ions can also strengthen the oxidation process of brain tissue, allowing the brain tissue to obtain more oxygen. 2. Impact on the cardiovascular system: According to observations by scholars, negative ions can significantly expand blood vessels, relieve arterial vasospasm, and achieve the purpose of lowering blood pressure. Negative ions are also very beneficial to improving heart function and myocardial nutrition, which is beneficial to high blood pressure. Recovery of patients with blood pressure and cardiovascular and cerebrovascular diseases. 3. Impact on the blood system: Studies have confirmed that negative ions can slow down the flow rate of blood coagulation and prolong the coagulation time. They can increase the oxygen content in the blood and are beneficial to blood oxygen transport, absorption and utilization. 4. Negative ions have an obvious impact on the respiratory system: This is because negative ions enter the human body through the respiratory tract, and they can increase people’s lung capacity. Someone once tested that inhaling negative air ions in a glass mask for 30 minutes can increase the amount of oxygen absorbed by the lungs by 20%, and the amount of carbon dioxide emitted can increase by 14.5%. Therefore, negative ions can improve and increase lung function.
