Abstract: The textile industry in China, where both the economy and technology are rising quickly, has a new market thanks to bionic technology. The fusion of fabric and bionic technology to create electronic fabrics with various functions, such as thermal insulation, structural color generation, and superhydrophobicity, is anticipated to play a significant role in the fields of health detection, intelligent medical care, motion monitoring, and human-computer interaction in a variety of smart wearable devices.
Bionic design of fiber materials is a key strategy for the textile industry to produce textiles with superior qualities. To acquire the excellent functions brought about by these unique structures for the prepared smart textiles, smart bionic textiles are primarily designed to respond to external environmental stimuli inspired by the structure and characteristics of live organisms in nature. Bionic technology has advanced significantly as a result of the ongoing advancements in intelligent technology and biological science, and it is increasingly being used in the textile sector.
The most typical representatives of insulation textiles based on bionic design are polar bears and penguins, whose internal structure is showing a hollow porous structure, and this porous structure enhances their thermal insulation performance. The hollow structure of fibers traps a large amount of air to increase thermal resistance or mimics the internal structure of polar bear hair or penguin feathers to develop heterogeneous fiber fabrics with special cross-sectional shapes. Next there are down of animals such as geese and ducks, whose internal structure shows a branching structure and whose thermal insulation properties are mainly attributed to their nano-scale and the trapped air in the branching structure. An environmentally friendly structured color-generating technology has been developed as a result of China's pressing need for the development of green textiles and eco-textiles. The idea that the shimmering butterfly's wings in the Amazon River Basin produce structural color has a significant impact on how color is generated.
The most typical superhydrophobic textile based on bionic design is a plant with self-cleaning function, which is represented by lotus leaf and water strider leg. There is a nanostructure on the micron structure mastoid on the surface of lotus leaf. This combination of micron structure and nanostructure is the fundamental reason for the self-cleaning function on the surface of lotus leaf. A number of researchers have produced excellent superhydrophobic fabrics mimicking the structure of lotus leaves and water strider legs. The fibers, fabrics, and textile sensors created through the fusion of bionic design and smart sensing textile materials, inspired by the structure of living organisms like spider hair, pale ears, and human skin, have great potential for advancement in the fields of protection, sports, medicine, and military.
The use of bionic techniques to create textiles with a variety of purposes has grown to be a crucial component of smart textile design. These techniques are inspired by the shapes and structures of living organisms found in nature. The use of bionic smart textiles is currently expanding into the medical, aeronautical, and military industries in addition to serving people's clothing requirements. The structure and application areas of multifunctional bionic smart textiles need to be further explored, notwithstanding the impressive achievements that have been obtained by smart textiles created by using bionic technology.
