Embodiment 1
[0044] see figure 1 and figure 2 , a bionic thermal insulation composite fabric, comprising at least two unit layers 6 stacked layer by layer, the unit layer 6 is a layered structure; the unit layer 6 sequentially includes a particle layer 3, a film layer 2, and a base layer from top to bottom 1. The top surface of the base layer 1 is bonded to the bottom surface of the film layer 2, and the top surface of the film layer 2 is bonded to the bottom surface of the particle layer 3. The particle layer 3 is composed of a plurality of micron-sized particles 31, The membrane layer 2 is a gas-permeable membrane whose outer surface is provided with pores; the bottom surface of the particle layer 3 and the top surface of the membrane layer 2 penetrate each other to form a permeable layer 4, and the permeable layer 4 includes a plurality of capsule bodies 5. The body 5 includes an air capsule 51 and the particles 31 inside it, and the outer skin 52 of the air capsule 51 belongs to the ...
Embodiment 2
[0046] Basic content is the same as embodiment 1, the difference is:
[0047] The outer capsule skin 52 of the air capsule 51 includes an upper capsule skin 53 and a lower capsule skin 54, the upper capsule skin 53 and the lower capsule skin 54 all belong to the film layer 2, and there is a gap between the upper capsule skin 53 and the lower capsule skin 54. An air capsule 51 containing still air 7 , the inside of which is provided with particles 31 . Preferably, the capsules 5 are arranged at intervals, and a spacer film block 21 is arranged between adjacent capsule bodies 5 , and the spacer film block 21 belongs to the film layer 2 .
Embodiment 3
[0049] Basic content is the same as embodiment 1, the difference is:
[0050] The particle 31 is a hollow or solid structure; when the particle 31 is a hollow structure, the volume of the inner cavity of the particle 31 is greater than the volume of the outer wall of the particle 31 . When the particle 31 is a hollow structure, its shape is preferably a sphere, an ellipsoid, an olive or other spheroids. When the particles 31 have a solid structure, preferably the particles 31 are micron-sized calcium oxalate crystal particles.
