Negative ion fiber is a new type of functional fiber that has only appeared in recent years and has become rapidly popular.
In recent decades, scientists have conducted extensive research on the biological effects of negative ions and confirmed that negative ions in the air have a significant impact on people’s mood, energy and health.
First of all, when people are in an environment rich in negative ions, they will feel that the air is particularly fresh and their mood will be particularly good. Secondly, negative ions have obvious auxiliary therapeutic effects on certain diseases. Research also shows that negative ions have a significant effect on reducing the content of 5-hydroxytryptamine (5HT) in the body. 5-hydroxytryptamine is also called serotonin. Serotonin is a vasoconstrictor that can accelerate the aging of the human body. After a person inhales negative ions, it will reduce the serotonin content in the intestinal mucosa, pineal gland and central nervous system, thereby delaying aging.
Methods to generate negative ions
The negative ions in the air are mainly negative hydroxyl ions (H3O2-), negative hydroxide ions (OH-) and negative oxygen ions (O2-) that exist in the hydrated ion state. Among them, the hydrated hydroxyl ions are beneficial to human health. People usually Call it a negative alkaline ion. There are great differences in the concentration of negative ions in different environments. After realizing the beneficial effects of negative ions on human health, people always try to increase the negative ion content of the surrounding environment through artificial means to improve the living and working environment.
Methods for artificially generating negative ions usually include:
Water spray method: Using the Leonard effect, high-pressure air or high-pressure water is used to spray water into mist-like droplets, causing them to hit certain hard surfaces, causing the continuous rupture of the water droplets to form positive and negative ions in the air.
Corona discharge method: Using the corona method, the electrode is discharged to ionize the air, the positive ions are absorbed by the cathode plate, and the negative ions are blown out by the air flow.
Radioactive source method: Use radioactive substances with small radiation doses to ionize the air.
Natural ore method: The use of certain natural ores to ionize the air and release negative ions under specific conditions, such as changes in temperature, humidity, pressure, and low-radiation excitation.
In fact, in some large landscape places, it is quite common to use the water spray method to increase the concentration of negative ions. Negative ion generators produced using the corona method have also entered shopping malls, offices and homes. The radioactive source method has been effective due to its safety assessment. Sex is not yet accepted by most people and has not been effectively utilized, while the natural ore method has been widely used in textile products.
At present, negative ion technology is mainly used in textile products in two ways, one is post-finishing, and the other is blending and spinning to produce negative ion fibers.
