Embodiment Construction

[0044] Describe the present invention in detail below in conjunction with embodiment and accompanying drawing. The embodiment is based on the specific implementation carried out on the premise of the technical solution of the present invention, and provides detailed implementation methods and processes. However, the protection scope of the claims of the present application is not limited to the description of the following embodiments.

[0045]The method for testing the radiation protection performance of textiles designed by the present invention is characterized in that the method adopts the following steps:

[0046] 1) Set up the test environment: This test method must be carried out in an environment of (20±2)°C and a relative humidity not higher than 40%. Test under normal constant temperature and humidity conditions, because the relative humidity is too high, it will affect the accuracy of the experiment.

[0047] 2) Sampling:

[0048] ①The sample shall not be less th...

Abstract

The invention discloses a textile radiation-proof property testing method. According to the method, under the conditions of certain temperature and humidity, textile fabric is placed between a signal source and a signal receiver, the obtained signal strength is compared with the signal strength under the condition that no textile fabric is placed, calculation formulas are selected according to data collection units, and the electromagnetic shielding effectiveness or the signal attenuation rate is calculated. The radiation-proof property of the textile fabric is evaluated quantitatively. The method adopts a shielding room method, and defects that a far field method and a near field method are affected by testing materials and the repeatability is poor are overcome with adoption of a self-designed test system; defects that the near field method is affected by operation errors, the accuracy is low and the like are overcome; the experimental repeatability is good, and the test result is accurate and reliable.

Description

technical field [0001] The invention relates to textile detection technology, in particular to a method for testing the radiation protection performance of textiles. Background technique [0002] Today, with the rapid development of modern science and technology, the environmental pollution caused by electromagnetic radiation is becoming more and more serious. It has been called by the World Health Organization as the fourth largest global public hazard after water, air and noise, and has become an invisible "killer" that endangers human health. . The World Health Organization and many countries, including my country, have put reducing the intensity of electromagnetic radiation, preventing pollution, protecting the environment and protecting public health on the most urgent agenda. [0003] The main hazards of electromagnetic radiation are: [0004] 1) Thermal effect [0005] 2) Non-thermal effect: (1) Effect on biological blood characteristics; [0006] (2) The influenc...
