Embodiment 1

[0035] This embodiment provides a biomimetic textile based on a fractal self-similar structure. The biomimetic textile is composed of a number of fibers having a fractal self-similar structure similar to the structure of silkworm cocoons. The fractal self-similar structure has multiple levels along the thickness direction of the biomimetic textile. structure. The specific number of levels in the multi-level structure needs to be determined in combination with the actual usage. The structural diagram of the fractal self-similar structure is as follows figure 1 As shown, it is a dendritic hierarchical structure with fractal self-similarity, in which, the side with higher density of graphic distribution is the upper surface, and the side with lower density of graphic distribution is the lower surface. For wearing textiles, if the lower surface touches the skin, the sweat can be quickly discharged from the body. This function is suitable for use in hot weather; on the contrary, ...

Embodiment 2

[0037] This embodiment provides a biomimetic textile based on a fractal self-similar structure. The biomimetic textile is composed of several porous structures with a fractal self-similar structure. The fractal self-similar structure has a multi-level structure along the thickness direction of the biomimetic textile. The specific number of levels in the multi-level structure needs to be determined in combination with the actual usage. In this embodiment, the number of levels in the multi-level structure is four. The structural diagram of the fractal self-similar structure is as follows figure 2 As shown, it is a hole-like hierarchical structure with fractal self-similarity, and the shape of the hole is a rectangle. It is also possible to change the shape of the hole, such as oval, circular, etc. The side with higher pattern distribution density is the upper surface, and the side with smaller pattern distribution density is the lower surface. The textile can achieve the sam...

Embodiment 3

[0039] This embodiment provides a kind of bionic textiles based on fractal self-similar structure, such as image 3 As shown, on the basis of Example 1, in combination with nanotechnology, nanoparticles (preferably silk fibroin nanoparticles) or nanofibers 1 are sprayed on the upper surface of the textile, and the fibers can present different forms, such as porous nanofibers, sawtooth nanofibers Fibers and beaded nanofibers, and thus the morphology and number of layers of the hierarchical structure can be changed. At the same time, when the scale tends to be very small, the nano-effect is very significant. The biomimetic textile with this design structure also has the function of the textile in Example 1.

Abstract

The invention relates to a bionic textile based on fractal self-similar structures. A plurality of fractal self-similar structures are arranged in the bionic textile; in the thickness direction of thebionic textile, the fractal self-similar structures form a multi-level structure, and the density of graphs in the fractal self-similar structures gradually decreases or increases. The bionic textilehas multi-level fractal self-similar structures similar to silkworm cocoons and has good unidirectional heat and damp conductivity, and through the performance, the damp conductivity efficiency and the warming performance of the textile can be effectively improved and the functions thereof in discharging sweat and conducting damp in hot days and providing comfort and warming in cold days are achieved.

Description

technical field [0001] The invention relates to the field of textile materials and textile structure design, in particular to a bionic textile based on a fractal self-similar structure. Background technique [0002] The heat and moisture conductivity of fabric is an important factor affecting the wearing comfort of textiles. Whether it is heat-conducting and breathable summer fabrics or heat-insulating and warm-keeping winter clothing, it is closely related to the types of fibers that make up the fabric, its structural shape, and the way fibers are packed in the fabric. Therefore, an important method to improve the heat and moisture conductivity of fabrics can be based on the nature and structure of fibers, optimize the orientation and arrangement of fibers in fabrics, and endow them with specific internal structural forms. [0003] Silkworm cocoons are known as "breathing natural fibers". In extreme environments (such as 40°C or -40°C), silkworm cocoons can protect silkwor...
