Abstract

The invention discloses a continuous microfiber separation technology improving metal radiation resistance. The technology steps are simple, the operation method is simple and convenient to implement,and the cost is low. Electroplating is adopted after the drawing process so that toughness, corrosion resistance, the fracture elongation rate and electric conductivity of metal fibers can be obviously improved. In addition, according to the metal fibers manufactured through the technical scheme of the continuous microfiber separation technology, due to the continuous drawing process, the manufactured metal fibers are small in diameter and large in length; and in addition, radiance resistance clothes manufactured through the metal fibers manufactured through the continuous microfiber separation technology are soft and comfortable and have high radiation resistance, and harm of radiation to the human body can be reduced.

Description

technical field [0001] The invention relates to the field of metal fibers, in particular to a continuous microfiber separation process for improving metal radiation resistance. Background technique [0002] As we all know, in modern life, various electronic devices, such as computers, mobile phones, microwave ovens, etc., produce a large amount of electromagnetic radiation. Scientific research and experiments have proved that these radiations are harmful to the human body and should be avoided as much as possible, especially for pregnant women and infants. , should reduce and avoid receiving these radiations. [0003] The existing anti-radiation clothing on the market mainly reflects external electromagnetic radiation through the shielding layer of metal fibers, so as to avoid these radiations from entering the human body. However, the diameter of the existing metal fibers is relatively large, so that the radiation protection performance of the radiation protection clothing...
