Far infrared fiber is a kind of electromagnetic wave with wavelength of 31000 m. It has good thermal effect because of its resonance with water molecules and organic compounds. In far-infrared fibers, ceramic (functional metal oxide) powders emit far-infrared rays at normal body temperature.
Far-infrared fibers refer to the addition of powder containing far-infrared function (some functional metal or non-metallic oxides, pulverized to nanoscale or micro-nano-scale powders) in the spinning process, and then evenly blended and drawn. The far-infrared function achieved by this method is very functional and will not disappear with washing.
In recent years, it has been widely concerned and has been put into production and use, which is made by adding far-infrared absorbent (ceramic powder) into the fiber processing process, and is a positive and efficient heat-insulating material, and the far-infrared ray of the radiation also has the active cell tissue. In the mid-1980s, Japan was the first to develop and introduce far-infrared fabrics to the market.
At present, the combination of far-infrared fiber and magnetic therapy are becoming a composite health care fabric.
Breathable antivirus clothing is a kind of skin protective equipment that can penetrate air and moisture, but can prevent toxic gases, droplets, bacteria and radioactive dust from causing harm to human body. It has many functions, such as antivirus, breathable, heat dissipation, high temperature resistance and flame-retardant, anti-detection camouflage and so on, so that the physiological properties of human body are obviously improved. The early breathable antivirus clothing originated in the United States in the 1920s, when the US military impregnated the disinfectant with chlorinated paraffin, forming an absorptive protective suit that could react with the agent and eliminate it. However, the protective clothing has a strong selectivity for the adsorption of the agent. It also has some irritating effect on skin, unstable property and corrosion effect on fabric, which affects the service life of clothing. After nearly a century of development, relatively mature breathable antitoxic clothing has been developed in various countries, most of which are adsorbed by activated carbon, but this kind of adsorptive material also has non-selective adsorption, so it has poor protection performance against large toxic agent droplets, and is easy to produce secondary pollution and other problems. Therefore, in recent years, various countries have been committed to the development of new materials and new technologies.
Uruguay's sheep exports reached $328 million in 2018, which was the highest since 2014. The export of wool and its derivatives amounted to $252 million, accounting for 70% of the total export value.
Wool exports rose 2 percent year on year in 2018, but exports rose 19 percent year on year as wool prices rose, with dirty wool exports up 32 percent.
From the point of view of export destination, China is the largest export destination of wool from Ukraine. In 2018, the value of imported dirty wool, wool washing and wool sliver from Uruguay accounted for 5975% and 25% of the export of similar products, respectively. Another major export market of Uruguay is mainly woolen wool imported from Ukraine by Germany: Germany imported wool from Ukraine 17% more in 2018 than the same period a year earlier, far exceeding the total amount of dirty wool and wool scouring imported from Ukraine.
