The rapid development of my country's manufacturing textile industry, the continuous expansion of market applications, and the continuous improvement of quality and efficiency have become a new growth pole of the textile industry. New textile products are emerging one after another. Here are two and three types of new textiles that emit radiation! Anti-X, γ-ray protective textiles X-rays and γ-rays are a kind of short-wavelength electromagnetic waves with the same properties, but they are produced in different ways. They can penetrate cells, damage DNA, and induce certain cancer cells. X-rays can destroy red blood cells and may induce hidden dangers such as leukemia. To prevent X and γ rays, the modified fabric can be treated by immersion in lead acetate solution to improve the activity of X-ray protection. Japan discloses the method of spinning by adding barium sulfate to the viscose solution and ion exchange fibers to adsorb lead and iron. The method of salt, etc., made a fiber with radiation shielding function. Protective textiles against neutron rays Neutrons have no charge and have strong penetrating power. Materials that can effectively block X-rays and down-rays often do not have good neutron radiation protection capabilities. It is very harmful to the human body, causing hematopoietic organ failure, digestive system damage, and Central nerve injury. It can also cause cancer, leukemia, cataracts, etc. The study found that the anti-neutron radiation clothing can use ion exchange fiber to absorb the ionic compound of boron or file to prepare the method of anti-neutron radiation fiber, and add rare earth metal oxidation during the polycondensation reaction of dimethyl terephthalate and ethylene glycol. After the polymerization, melt spinning and other methods are used to prepare the anti-neutron radiation fiber. Far infrared protective textiles Far-infrared textile refers to a new type of textile that improves the far-infrared function by scientifically adding far-infrared emitters (such as far-infrared ceramic powder) to the fiber-forming polymer and the slurry after printing and dyeing. It is a kind of functional textile emerging in recent years, which has the functions of keeping warm and warming up. Far-infrared health care finishing fabric shells are used to develop heat storage products and medical supplies that protect health, such as underwear, personal thermal clothing, bed sheets, bedspreads, blankets and other bedding, cushions, knee pads, belts, deodorant footwear and electric heating products. Far-infrared fabric is an active thermal insulation material, that is, it can absorb and store external heat, and then radiate to the human body. Mechanism: By adding far-infrared radioactive materials to the fiber or fabric, it can absorb the heat emitted by solar energy and the human body, and emit the far-infrared rays needed by the human body, and use the warming effect of the far-infrared rays on the human body to be positive The role of warmth. |
