Problems solved by technology

However, subsequent studies found that wood liquefied carbon fibers are non-graphitizable structures with a large number of defects and pores, and their strength can only initially reach the strength level of commercial PAN-based and pitch-based carbon fibers, making it difficult to prepare high-strength, high-modulus carbon fibers. amount of carbon fiber
[0006] In the prior art, the Chinese patent whose authorized notification number is CN 103451920 B discloses a preparation method of silver-loaded active wood carbon fiber, but the fiber prepared according to the invention only has a certain bactericidal performance and does not have radiation protection performance. The function is relatively simple

Abstract

The invention provides an antibacterial radiation-proof fabric and belongs to the field of textiles. A preparation method of the antibacterial radiation-proof fabric comprises the steps of wood liquefaction, preparation of spinning liquid, preparation of wood fibers, preparation of the fabric, smearing of silver seepage solid liquid and ultraviolet irradiation seepage. According to the preparationmethod disclosed by the invention, the antibacterial property and the radiation-proof property of the fabric are effectively improved by improving preparation processes of the wood fibers and the silver seepage solid liquid. In a 2-hour antimicrobial experiment, the sterilization rates of the fabric to escherichia coli and staphylococcus aureus both reach 100 percent and the radiation shielding efficiency of the fabric to 1000MHz frequency is up to 70dB.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to an antibacterial and anti-radiation fabric. Background technique [0002] Silver fiber and fabric penetration technology is a hot research direction. At present, a large number of top companies have been committed to the research and development of this field for a long time. However, due to factors such as complex technology and high research costs, the research progress in this area is slow and the results are not many. . [0003] Antibacterial fabrics in the prior art are mainly divided into two types: one is the built-in silver ion antibacterial fabric, which uses spinning-grade antibacterial technology to directly put the antibacterial agent into the chemical fiber; The process is added: electroplating, electroless plating (deposition method) vacuum sputtering (complexation method), these methods metal is only distributed on the surface of fibers and fabrics, not resistant to washin...
