What are the specific categories of special fibers?
Special fibers have very special physical and chemical structures, which can be used for multiple widespread behaviors and are classified into functional types such as corrosion resistance, high temperature and flame resistance. Firstly, we can take a look at the things currently produced in industrialization, such as polytetrafluoroethylene, which is relatively common and has a high range. Even this thing that can dissolve gold has no effect.
Special fibers have very special physical and chemical structures, which can be used for multiple widespread behaviors and are classified into functional types such as corrosion resistance, high temperature and flame resistance. Firstly, we can take a look at the things currently produced in industrialization, such as polytetrafluoroethylene, which is relatively common and has a high range. Even this thing that can dissolve gold has no effect.
It can be used for making various corrosion-resistant gases or filtering materials, as well as sealing materials. It is difficult to burn in high oxygen environments, so the temperature range of use is also relatively wide. The climate is relatively good, and even if left outside for 15 years, there will be no aging. This is probably how space suits do it. Such special fibers have low conductivity and thermal conductivity, making them excellent materials in high temperature and high heat environments.
And the resistance to fading and wear in this temperature resistant zone are relatively strong, but so far no solvent will dissolve, so it is not suitable for making this textile. Another type of fiber that can be used at temperatures ranging from 200 to 230 degrees Celsius is heat-resistant fiber, which does not soften at high temperatures and can maintain certain mechanical properties. So what is this? It is aramid -1313. A type of fiber that has been available since 1967, with a melting point of 400 degrees,.
After heating at 260 degrees, the strength still remains at 65%, indicating strong corrosion resistance. So when it comes to this high level of practicality, what is it? This is high molecular weight polyethylene. Under normal circumstances, most of them are in a folded structure and have a relatively long length, making them difficult to dissolve even when using many substances as solvents. Even after long-term soaking, there will be no deformation.
Special fibers are more suitable for working in the sea, such as some ropes or cables, which can float in the water without restrictions. They are good materials for ocean use, and are all special fibers.
