Large fibers have an inherent cross-disciplinary, interdisciplinary cross-characteristic. Its theoretical foundation and technical route also show the vitality of a hundred flowers. Under the guidance of structural optimization theory, the development of fiber-based multi-material, multi-structure multi-functional intelligent fiber; under the guidance of nano-theory, the development of high-functional fibers based on carbon nanotubes and graphene; under the guidance of polymer design theory, Develop ultra-high performance fibers from molecular structure; under the guidance of synthetic biology theory, create high-performance bio-fibers through transgenic technology.
Cross-disciplinary and interdisciplinary cross-integration will create many completely new fiber varieties, of which a considerable proportion of fiber varieties have great commercial value, which will have a profound impact on many downstream industries and fundamentally change the ecology of these industries. Thus, a huge emerging industrial cluster was born. We call the large fiber-related technologies, products, and new industrial clusters formed around the rich downstream applications as the large fiber industry.
In recent years, the development of the large fiber industry has begun to emerge, and the new intelligent fiber family across the field and interdisciplinary is constantly “increasing”. The high thermal conductivity fiber developed by Professor Chen Gang of MIT (Massachusetts Institute of Technology) overturned the adiabatic theory of traditional polymer materials. Through stretching and reconstitution, the polymer chains in the fibers were arranged in an orderly manner, and an "ideal" single crystal structure was obtained. And high thermal conductivity fibers; Stanford University professors based on functional requirements, based on physical principles developed a silicon nanowire battery anode, nano-polymer fiber PM2.5 filter membrane and nanoporous polyethylene fabric; Changsheng Textile Technology Development (Shanghai) Co., Ltd. uses the cold transfer technology to accurately quantify the printing and dyeing, subverting the printing and dyeing process of using a large amount of diluted dyeing liquid for thousands of years, achieving basic waterless consumption, non-emission printing and printing, and directly on the fabric. Printing and dyeing high-precision functional lines and patterns has become a platform-level technology for the development of intelligent electronic fabrics.
At the same time, large fiber technology has broken through the manufacturing bottleneck of the original technology. For decades, spider silk has not been made using traditional chemical synthesis theories and methods. Nowadays, using biosynthesis theory, protein molecules of silkworms and bacteria are regulated by spider genes, and high-performance spider silk has been mass-produced. This is considered to be the most important advancement in textile materials since the advent of nylon.
Compared with traditional materials such as steel and plastic, large fibers have obvious advantages in terms of flexibility, light weight, versatility, high performance, greenness and intelligence. In the traditional advantages of high-performance steel such as automobile and aircraft manufacturing, the proportion of fiber composites has become higher and higher in order to achieve higher flexibility, light weight and high energy efficiency. At the end of 2018, some media reported an example of a smart carbon fiber car body, which not only achieves lightweight body, but also can be deformed according to wind resistance. The carbon fiber body is made of 3D technology (completely eliminating the metal processing steps such as cutting, stamping, welding, etc.), and the fiber with solar power generation function is mixed in the fabric, which can replace some batteries, and the use of multifunctional carbon fiber makes the whole vehicle The price/performance ratio has been greatly improved. This is a typical example of the application of large fiber parts to replace traditional materials.
In fact, all previous industrial revolutions were inseparable from the redefinition of the relationship between humans and man-made systems, centering on "people-oriented". It is well known that more than 70% of the tissues of the human body are composed of fibers. The biocompatible green fiber superimposes intelligent and versatile elements, resulting in a new generation of intelligent wearable systems or human implantable systems that can collect human data and monitor in the safest, lightest and most efficient way. Human health, exerting effective influences and helping people improve their health and exercise levels. The “digital person” formed based on the collected data will become one of the most important assets in the artificial intelligence society. Only at this stage will social digitalization be realized, and large fiber will become the best bridge between the human world, the physical physical world and the virtual information world.
