- the water in the trickle is rapidly evaporated, the fiber is solidified, and the gel is elongated and formed under the action of the winding force of the collecting roller, and then the gel fiber is calcined in a high temperature furnace to form an oxidation.
- the fiber shrinks due to thermal decomposition, and friction between the fiber filaments forms a strong electrostatic effect.
- the fiber bundle is affected by strong electrostatic action. Sex, together with the fiber surface is not lubricated, the alumina fiber itself is less flexible.
- the twisting force causes the fiber to break, affecting the performance of the fiber bundle, and thus affecting the finished product of the alumina continuous fiber.
- it is necessary to surface-modify alumina continuous fibers to eliminate static electricity, impart certain flexibility and surface lubricity to the fibers, and integrate hundreds or even thousands of fiber monofilaments to make fibers. Successful completion of the joint-stock twisting process.
- Fiber surface modification technology can be roughly divided into three categories: plasma modification, oxidation modification technology and coating modification technology.
- the plasma modification technology can improve the properties such as fiber wettability, cohesiveness, hydrophilicity, and disinfection and cleaning of fibers (see: Bi Songmei et al., Industrial Textiles 2013, 6, 32-35);
- the technology is further divided into electrochemical oxidation, gas phase oxidation and liquid phase oxidation.
- the treatment of fibers by oxidation modification technology can improve the surface state of fibers (see: Zhang Meiyun, Proceedings of the 13th Annual Conference of China Paper Association (Part 2) , 2008); coating modification technology generally by preparing a fiber-specific sizing agent, using a coupling agent to graft a polymer film forming agent on the surface of the fiber, surface modification of the fiber, improve fiber bundle, lubricity, resistance Friction and other properties (see: Jiang Xue, basalt continuous fiber special sizing agent research, Harbin Institute of Technology Master thesis, 2009).
