Problems solved by technology

This type of fabric is highly designable, soft, and comfortable, and can achieve a high blending ratio and high electromagnetic shielding performance, but because the conductive fibers used in this type of textile are all metallized nylon (nylon) or polyester (polyester) fibers , the common problem of this kind of material is that it melts and drips when exposed to open flame or high heat, so it can only be used in ordinary civilian fields, and it is difficult to be used in high-end civilian and military applications with high-temperature flame-retardant requirements
[0012] Combining the above three types of electromagnetic shielding fabrics, they are not suitable for occasions that require high electromagnetic shielding, high temperature flame retardancy and wearing comfort, such as radar workstations, ships and aircraft cockpits, medical treatment, electric power, mining and petrochemicals.

Abstract

The invention discloses a flame-retardant electromagnetic shielding fabric and a preparation method thereof, and belongs to the technical field of textile materials for electromagnetic protection andpreparation methods thereof. The metalized flame-retardant fiber with good spinnability and flexibility and other flame-retardant fibers are blended and woven to obtain an electromagnetic shielding fabric which is based on the full-flame-retardant fiber and has good high-temperature flame-retardant performance, excellent electromagnetic shielding effect and good wearing comfort at the same time. The fabric and the preparation method overcome the inherent defects that a metal fiber blended fabric is limited in shielding effectiveness and poor in comfort, and a common metallized organic fiber blended fabric is not resistant to high temperature and poor in flame retardance; and the prepared flame-retardant electromagnetic shielding fabric can be used for meeting the electromagnetic protectionrequirements of occasions with higher requirements on electromagnetic shielding, high-temperature flame retardance and wearing comfort, such as radar workstations, naval vessels, airplane cockpits, medical treatment, electric power, mines, petrochemical engineering and the like.

Description

technical field [0001] The invention relates to a protective fabric and a preparation method thereof, in particular to a textile material with flame-retardant and electromagnetic radiation protection functions and a preparation method thereof, belonging to the field of textile materials for electromagnetic protection. Background technique [0002] With the rapid development of science and technology and the electronic industry, electronic products play an irreplaceable role in human daily life and work, but at the same time, the hazards of electromagnetic radiation are becoming increasingly serious. The current research results show that long-term exposure to a strong electromagnetic environment or exceeding a certain dose of electromagnetic radiation will cause a certain degree of damage to the human central nervous system, blood system, reproductive system, eye lens and retina. In addition, electromagnetic radiation will cause some damage. An abnormal chemical reaction tha...
