Radiation-proof fabric and production process thereof

Abstract

The invention relates to a radiation prevention facing material and manufacturing technique thereof. The radiation protection facing material is principally formed by mutually interlacing a set of warp thread and a set of weft thread, a set of warp thread includes a plurality of warp thread stainless steel wires, a set of weft thread includes a plurality of stainless steel cladding threads which are composed by cladding and winding stainless steel wire on the terylene silk thread or real silk silk thread, and a shielding meshwork with radiation protection function by mutually interlacing the cladding thread and the weft thread stainless steel wire. The manufacturing technique of the radiation protection facing material includes in sequence a single filament twisting process, a fiber strand process, a coating process, a warping process and a weaving process, the tensile force of the silk thread is strictly controlled in these processes. The inventive radiation prevention facing material has good electro-magnetic screen effect, permanent radiation protection function and low production cost.

Description

technical field [0001] The invention belongs to the field of woven fabrics, in particular to a radiation-proof fabric and a production process thereof. Background technique [0002] With the rapid development of the textile industry, fabrics have also ushered in their new era, and people have higher and higher requirements for modern fabrics, and more and more functional features. [0003] In the prior art, there are mainly three types of anti-radiation fabrics: one is to use metal or conductive fiber and other fibers to blend or interweave, which has a certain anti-electromagnetic radiation effect, but the effect is not ideal; the other is to use a coating agent containing conductive materials Coating the fabric has a certain anti-electromagnetic radiation effect, but its durability is poor; the third is to form a conductive film on the surface of the fabric by coating the fabric, which has a good anti-electromagnetic radiation function, but its Higher cost and poor durabi...

AI Technical Summary

Problems solved by technology

[0005] 1. Metal or conductive fibers are blended or interwoven with other fibers, because the conductivity of the blended spun yarn itself is not as good as that of metal wires, and spun yarns inevitably have spun filaments mixed in the fabric mesh nodules, thereby increasing The resistance at the node reduces the conductivity and affects the radiation protection effect of the product;

[0006] 2. After the fabric is made into clothing, it is inevitable to wash it. After repeated washing, the surface of the fabric is worn, the conductive fibers fall off, and the electromagnetic shielding effect of the fabric is reduced and cannot last;

[0007] 3. Compared with the metal wire, the conductive fiber has a large resistance and poor conductivity. Therefore, the shielding effect of the electromagnetic shielding net formed thereby cannot be optimal.
