The development of fiber nanotechnology

to manufacture "fine and strong" fibers by Teijin company of Japan has been a basic proposition for synthetic fiber technology developers since the birth of synthetic fiber until today. Recently, the industry has high expectations for nano materials, hoping to minimize the fiber to nano size to produce a new function of "nano size effect". However, at present, the strength of nano-sized fibers will be reduced in the mass production stage, so they can only produce short fibers, which can not fully meet the needs. It is learned that when the fiber company newly developed the epoch-making "island cross-section conjugate spinning", as an important part of the oil pan as an automobile part, it successfully realized the development and commercialization of the "nano Frunt TM" which can cope with the mass production of high-strength polyester nano fiber filament

this "nano Frunt TM" is a synthetic fiber of nanotechnology materials, which has large friction, soft hand feel, superior wiping performance, and is thin and difficult to be ldquo; 1035 rdquo; During this period, it pointed out the impermeability and other characteristics of the top-level design for the development of China's new material industry. This technology won the 2008 Japan fiber society technology award

the main content of this technology is: in the conjugate spinning of island cross-section of general microfiber, the island part in one fiber becomes dozens after dissolution treatment. In this regard, the researchers of the winner Teijin fiber company of Japan developed the "new island fiber splitting technology" and successfully put about 1000 islands in one fiber. As a result, superfine fiber filaments with a short fiber diameter of 700 nm and none so far have been produced. The key of this technology in recent years is the polymer technology including spinneret processing and ultra precision forming processing technology

the technology was evaluated as adopting epoch-making manufacturing technology that was not available before, realizing the dream of synthetic fiber technology developers for many years
