Far-infrared fabric is a kind of functional textile emerging in recent years, which has the functions of warmth and health care. There are two types of processing of far-infrared fabrics, one is processed by far-infrared fibers, and the other is processed by finishing. The nanometer far-infrared anion powder developed by our company not only has good heating and health care effects, but also has good hand feeling and fastness, and can develop a variety of health care and medical products.
  far infrared and negative ion function
  Infrared is an electromagnetic wave located between visible light and microwave, and its wavelength range is 0.76-1000um. It is customarily divided into three segments, near infrared, mid-infrared and far-infrared. Generally, the infrared between 4-1000um is called far-infrared. Any object in nature will absorb or radiate electromagnetic waves when the temperature is above the absolute temperature. Radiation is a process of energy transfer in order to eliminate energy imbalance after the object absorbs heat energy or heats itself to excite molecules or atoms. In the infrared radiation band, when the atoms or groups of atoms in a molecule change from a high-energy vibrational state to a low-energy vibrational state, far-infrared radiation of 2.5-25um will be generated. If the radiation source is radiation caused by the change in the rotational properties of molecules, far-infrared radiation greater than 25um will occur. Studies have shown that the energy of the vibrational spectrum is about 100 times that of the rotational spectrum. 2.5-25um is a high-energy-carrying wave, especially the 8-15um band of far infrared, which has good application value. Introduction to scientific and technological materials Far infrared has the following functions:
 
1, heat preservation function
 
The warmth of traditional clothing is to prevent the body's heat from dissipating outwards to achieve heat preservation, such as cotton wool, down, etc., and far-infrared fabrics can absorb external energy (such as solar energy, energy emitted by the human body) in addition to the above functions. ) And store it, and then feedback to the human body, so that the human body has a warm feeling and increase the human body temperature.
 
2, the role of medical care
 
The human body is a natural infrared radiation source, and its radiation frequency band is very wide. Regardless of the skin color, the specific emissivity of living skin is 98%. The thermal radiation wavelength on the surface of the human body is in the range of 2.5-15um, and the peak wavelength is about 9.3um. The radiation in the 8-14um band accounts for about 46% of the total radiation energy of the human body. According to Kirchhoff’s law, the human body is also a good infrared absorber. The absorption wavelength is mainly 8-14um. The mechanism of infrared radiation absorption is spectral matching resonance absorption, that is, when the radiation wavelength of the radiation source is When the absorption wavelengths are the same, the object absorbs a large amount of infrared radiation.
 
Modern medicine proves that many diseases are related to microcirculation disorders. Regarding the biological effects of infrared rays, some people explain that the frequency of far-infrared rays is consistent with the vibration frequency between the molecules and atoms that make up the biological cells, so its energy is easily absorbed by the biological cells, which increases the vibration within the molecules and activates tissue cells. Promote blood circulation, accelerate metabolism, increase blood flow on the body surface, and have a good warming effect. In addition, infrared radiation can also cause biological molecules to produce resonance absorption effects. Under the action of infrared photons, the molecular energy level of the object is excited to be at a higher vibrational energy level, which improves the activity of biological macromolecules such as nucleic acid and protein. Play its role in regulating body metabolism, increasing immune function, and improving microcirculation.
 
According to domestic and foreign technical data, the main functions of negative ions are:
 
A, hydrated hydroxyl ion (H3O2)-After entering the human body through breathing, it can adjust the blood pH and make human body fluids weakly alkaline. Weakly alkaline body fluids can activate cells, increase cell permeability, improve cell functions, and maintain the balance of Ca2+ ions; purify the blood, inhibit the formation of serum cholesterol, thereby lowering blood pressure; negative ions enter the body to increase oxygen conversion capacity, accelerate metabolism, and restore Or reduce fatigue, make people feel comfortable and relax the body and produce physical therapy healing effects.
 
B. It can activate the brain hormone β-endorphin, stabilize the autonomic nerve, control the sympathetic anion nerve, improve the sleep effect, and improve immunity.
 
C, hydrated hydroxyl ion (H3O2)-can react with odor molecules in the air to eliminate odor; it can neutralize the polluted positive ions in the air, thereby purifying the air.
