Application
Application of Pitch Melt Spinning Machine
Melt spinning machine refers to the machine use melt spinning method to produce synthetic fiber. Pitch Melt Spinning Machine Suitable for high polymers with melting point lower than decomposition temperature, such as polyamide, polyester, polyolefin, etc. Is one of the most important melt spinning methods.
Melt spinning Process:
Curing process refers to the transformation from spinning fluid to solid polymer, which is one of the most important parts of fiber forming. Curing process contains many structural materials and macro properties of irreversible change, in the aspect of structure such as molecular orientation, crystallization, etc., while the macro properties such as viscosity, modulus, strength, etc.
The forming of melt spinning, that is, the heat transfer of the filament, thereby solidifying the process. The curing rate is controlled by the cooling of the spinning line during the heat transfer process of the fine flow and the surrounding medium, accompanied by crystallization and molecular orientation. In polymer solvent binary system dry spinning, when the spinning fluid is transformed into solid fiber, in addition to heat transfer, there is also mass transfer. That is, in the drying process of spinning fluid, heat transfer, simultaneous solvent volatilization, polymer crystallization, molecular orientation and network structure gelatinization formation. And wet spinning is more complex, multi-component diffusion, followed by the change and the structure of polymer precipitation, crystallization, gel, in some cases, even accompanied by chemical reactions.
