Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a waterproof and radiation-proof fabric and a preparation method thereof. Background technique [0002] With the development of science and technology and the improvement of living standards, people have higher and higher requirements for clothing comfort. In order to meet the requirements of clothing comfort, the development of functional fabrics is essential. For example, during outdoor sports, people often sweat a lot, and also encounter bad weather such as fog and rain. This requires clothing fabrics to have waterproof, warm, and moisture-permeable functions to meet the high comfort requirements of outdoor sports. [0003] Various new industries characterized by automation and electronic control developed with the continuous updating of new electronic technologies have played a huge role in promoting my country's economic construction and technological progress. How...
