Spinning technology mainly includes the following:

Melt spinning. This method is suitable for high heat resistant polymer forming process, high polymer needs to have the performance of melting without decomposition. The melt spinning process is relatively simple, and the finished fiber can be obtained after the primary fiber is heat-shaped by the drawing machine.

Solution spinning. Including wet spinning and dry spinning. Wet spinning is suitable for polymer materials that cannot be melted and can only be dissolved in solvents or natural polymers and biomass materials that are sensitive to temperature and easy to degrade. The dry spinning method is suitable for the situation that the spinning solution can be made from a solvent with low boiling point and good solubility in the fiber forming polymer.

Wet and dry spinning. Combined with the characteristics of dry spinning and wet spinning, it is especially suitable for the forming of liquid crystal polymers.

Electrospinning. This is a direct continuous preparation of nanofibers technology, the use of high voltage electrostatic field to charge the polymer solution and generate shape electricity, forming a dangling cone droplet, through the high-speed stretching of the electric field force and solvent volatilization after curing, forming nanofibers.

The above spinning technologies have their own characteristics and are suitable for different types of polymer materials and production needs.
