Description

technical field [0001] The invention relates to the technical field of composite fiber production, in particular to a flexible antibacterial composite fiber flash evaporation system and a flash evaporation method. Background technique [0002] Flash spinning is a special case of dry spinning. The polymer rapidly forms fibers when the solvent flashes, also known as instant spinning. The spinning technology method is mainly: mixing the fiber-forming polymer with a solvent, the selected solvent has a boiling point lower than the polymer, and cannot dissolve the polymer at normal temperature and pressure; under the condition of pressure and heating, it can dissolve the fiber-forming polymer . When heated to a temperature slightly higher than the boiling point of the solvent, the polymer dissolves to make a spinning dope, which is then extruded from the spinneret hole and enters a low temperature (or normal temperature) and low pressure (or normal pressure) medium. The solvent ...

Problems solved by technology

This electrostatic production process has the following disadvantages: First, it is very easy to cause safety hazards, such as fires and explosions caused by static electricity; secondly, because the negative electrode and metal plate corona discharge are affected by conditions such as current stability, the stability It is difficult to control, resulting in different degrees of fiber opening and poor uniformity of web formation; again, it is difficult to control the stability of fiber drafting due to static voltage; in addition, due to electrostatic process, the speed of fiber coagulation is slow and the coagulation speed is not good. Adjustment and so on are the existing problems of electrostatic flash spinning, and most of the conventional flash spinning equipment uses electric energy or steam heating, which consumes a lot of energy. Therefore, to solve the above problems, a flexible antibacterial composite fiber flash system and flash method
