Far-infrared fabric is a kind of functional textile emerging in recent years, which has the functions of heating up, keeping warm, and health care. The company has successfully developed the far-infrared finishing agent JLSUN® 777 on the basis of the far-infrared pulp JLSUN® 700. It not only has good heating and health care effects, but also has a soft hand feel and good fastness. It can develop a variety of health care and medical treatments. product.
 Far infrared function
Infrared is an electromagnetic wave located between visible light and microwave, and its wavelength range is 0.76-1000um. It is conventionally 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 science and technology far infrared has the following functions:
 
1, heat preservation function
 The warmth preservation effect of traditional clothing is achieved by preventing the body's heat from dissipating outwards, such as cotton wool, down, etc., while far-infrared fabrics can also absorb external energy (such as solar energy, energy emitted by the human body) and store it in addition to the above functions. Get up, and then feed back to the human body, so that the human body has a warm feeling and raises 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 of the human body surface 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.
 
Instructions for far infrared finishing agent JLSUN 777
 
far-infrared finishing agent JLSUN 777 is mainly composed of far-infrared radiators JLSUN 777A and JLSUN 777B with higher emissivity at room temperature. It is suitable for far-infrared finishing of cotton, linen, silk, wool, viscose and other fibers containing amino or hydroxyl groups.
 
① The national far-infrared product supervision and inspection center and other authoritative organizations have tested and proved that the far-infrared emissivity of cotton fabric after far-infrared finishing is over 86%, and the far-infrared emissivity is still as high as 85% after 80 washings.
 
②The far-infrared finishing agent JLSUN 777 dyes cotton fibers in a single molecule state, and combines with the functional groups such as hydroxyl groups on the fibers with strong chemical bonds to form nano-level far-infrared emitters, which makes the products have good fastness, soft touch and moisture absorption Excellent air permeability.
 
1. Dipping method: (bath ratio 1:15)
 
Bleaching and dyeing → dipping far-infrared finishing agent JLSUN 777A (4% owf, cotton 60-70℃, wool 80-85℃, 30-40 minutes)-→ put out the residual liquid → spin dry or rinse in cold water → immerse JLSUN 777B (3% owf) , 40-50℃, 20-30 minutes) → put the remaining liquid → rinse with cold water (to prevent affecting the stability of the silicone oil softener) → apply the silicone oil softener → finished product.
 
2. Process flow of padding method:
 
Bleaching and dyeing → drying → padding JLSUN 777A (30 g/l, rolling rate of 60-70%) → drying (80-100°C, weak cloth falling) → padding JLSUN 777B (20 g/l, rolling solution Rate 60-70%)→drying (80-110℃)→tented finished product.
 
3. Matters needing attention:
 
1) The padding method is difficult to operate, and the strength is generally reduced by 10%; the dipping method has little effect on the strength.
 
2) After the padding far-infrared finishing agent JLSUN 777A is dried, the falling fabric must be slightly moist (the moisture content is about 8-15%), and the JLSUN 777B must be padding as soon as possible, otherwise the strength of the fabric will be seriously reduced.
 
3) When padding far-infrared finishing agent JLSUN 777B, it can be carried out in the same bath with softeners S-808 and S-666. If you use other brands of softener, please perform the same bath stability test of JLSUN 777B and softener first
 
4) At present, the testing methods of far-infrared products in the world are inconsistent. For export products, please let the customer confirm the samples before signing the order for production.
