Recently, the 10th functional textile and nanotechnology application seminar of "Snow Lotus Cup" was held in Changzhou, Jiangsu Province. Experts at the meeting pointed out: With the acceleration of integration of production, learning, and research, China's functional textiles R&D and application are rapidly developing beyond the textile and apparel industry, and are now moving toward construction, transportation, medical care, health, aviation, aerospace, water conservancy, transportation, and so on. Many fields such as agriculture, energy, military, and national defense are expanding.
Electrospinning is a highly efficient and low-cost preparation of nanofibers. In this seminar, twisted spiral nanofiber electrospinning technology, bicomponent spinning technology and coaxial electrospinning to prepare nuclear shell structure nanoparticle assembly technology have received widespread attention. Experts at the meeting introduced the latest research results in the field of nanotechnology in China's textile research institutes. For example, nano-carbon fibers developed by combining nano-manufacturing technology and high-tech carbon fiber materials can be used in filtration, tissue engineering, medical dressing, antimicrobial biomedicine, catalysts and other chemical reaction carriers and fine optical electronic materials. Range of application. At present, this technology in China has already reached the international frontier.
Tianjin University of Technology introduced microfiltration, nanofiltration and reverse osmosis series technologies. These technologies can be used not only for sea water and desalination but also for the separation and purification of various substances. The reverse osmosis membrane has been developed to the third generation and has been widely used. Experts and scholars from universities at home and abroad have also brought new research results in terms of new materials and new fibers. For example, based on polyester, nylon and polypropylene as the base material, the energy-storing multicolor luminescent fiber made through special spinning process can store light energy in fiber as long as it absorbs visible light for 10 minutes; it has been developed with pineapple leaves. The natural antibacterial function of pineapple leaf fiber has enabled the effective use of agricultural waste resources and has significant social and economic benefits.
