This invention discloses an infrared camouflage composite yarn, its preparation method, and its application. The preparation process involves first preparing a preform, then dispersing aluminum powder and tin-doped indium oxide powder on a softened film to form an infrared-resistant film. The infrared-resistant film is then coated onto the preform using a layered structure design to prepare a composite preform. Combined with heat treatment, the yarn is then hot-stretched to obtain the improved infrared camouflage composite yarn. The infrared camouflage composite yarn prepared by this invention not only possesses excellent infrared camouflage capability and durability, but the addition of functional particles does not significantly affect the yarn's mechanical properties, such as breaking strength. The functional particles maintain uniform dispersion, improving the uniformity of infrared camouflage performance. This method is suitable for preparing infrared camouflage products, such as military jackets, tents, and backpacks.
