Abstract:

In order to expand the preparation methods of nano/micro-fibers and broaden the source of medical protective suit fabrics, the research progress in flash spinning nano/micro-fibers nonwoven and the application as protective suit were reviewed. The types of raw materials used in flash spinning and the current problems were introduced, and the spinning technology, process and products were described. The research status and trends of flash spinning technology were summarized, while the characteristics and applications of flash spinning nonwovens were analyzed. The flash spinning nonwovens, due to their structural and property features, can be used as a protective fabric, and the classification and the existing problems in current use were discussed. The flash spinning technology is a nano/micro-fiber nonwoven fabric preparation technology with good development prospect at present, and it is of great significance to improve the technical level of China's nonwovens industry and protect people's health and life.

Key words: flash spinning, nano/micro-fiber, nonwoven, protective suit, spinning principle
