With the application of high-precision weapons and drones, detection on the battlefield means destruction. Therefore, using camouflage technology to weaken enemy detection has become an important means to ensure the combat effectiveness of the army. In actual wars, military equipment is prone to malfunction due to electromagnetic interference. At the same time, temperature changes caused by the operation of the equipment are also easily detected by infrared detectors and expose targets. Therefore, military electromagnetic shielding fabrics must also have infrared stealth functions to improve Security and camouflage of the protected target. At present, military stealth fabrics have shortcomings such as single performance, inability to have both electromagnetic shielding and infrared stealth properties, complex preparation methods, high cost, and poor durability, making it difficult to meet the equipment needs of large quantities of multi-functional military fabrics. In view of the complex and ever-changing combat environment, the development of low-cost, multi-functional military textiles that combine electromagnetic shielding, infrared stealth, flame retardancy, hydrophobicity and stability in complex environments is of great significance to improving the level of my country's military equipment.

To this end, the team of Professor Fan Wei of Xi'an Polytechnic University designed a multi-layer composite fabric, which combines hydrophobic flame-retardant aluminized aramid fabric (FH-Al) and flame-retardant carbonized waste cotton fiber needle felt (CR- WCN) and waste carbon fiber needle felt (CFN) are combined using a simple stitching process to prepare a multifunctional military textile material that integrates electromagnetic shielding, infrared stealth, hydrophobicity, flame retardancy and other functions, that is, a multifunctional aluminized resist Burning aramid-carbonized waste cotton fiber-waste carbon fiber composite fabric (A-FCWCF) has good development prospects.
