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.

Abstract

The invention discloses a biomimetic heat-preservation composite fabric which comprises at least two unit layers overlapped layer by layer, wherein each unit layer comprises a particle layer, a film layer and a base layer from top to bottom sequentially; the top surface of the base layer is adhered to the bottom surface of the film layer, the top surface of the film layer is adhered to the bottom surface of the particle layer, the particle layer comprises multiple micron-sized particles, the film layer is a breathable film with pores in the outer surface, the bottom surface of the particle layer and the top surface of the film layer permeate each other to form a permeation layer, the permeation layer comprises multiple capsules, each capsule comprises an air capsule and particles arranged therein, the outer capsule skin of the air capsule belongs to the film layer, and each particle is a hollow or solid structure and can be a calcium oxalate crystal particle. By such a design, not only can the advantages of lightweight, thinness, warmth keeping and breathability of the fabric be combined, but also the advantages of fine and soft touch, acid, alkali and high temperature resistance and insolubility in water can be achieved.

Description

technical field [0001] The invention relates to a bionic fabric, which belongs to the field of textile fabrics, and in particular to a bionic thermal insulation composite fabric, which is particularly suitable for ensuring the warmth retention while reducing the weight and thickness of the fabric. Background technique [0002] In order to adapt to the ever-changing environment, organisms in nature are constantly evolving and changing, thus creating a special function, optimal composition and structure to adapt to nature, so as to survive and develop. The natural world has always been the source of inspiration for human beings to invent and create. The progress of civilization and the realization of technological innovation are the result of continuous learning and imitation from nature. [0003] In recent years, textiles have rapidly developed from high-fashion to high-performance, intelligent, and multi-functional, which has brought about great changes in people's consumpti...
