The physical properties of polypropylene staple fibers can be derived from relevant experiments.

The main component of polypropylene fiber is polyethylene terephthalate, the mass fraction is about 99%, and the rest is ash, mainly TiO2, and its mass fraction is about 1%. The physical properties of polypropylene staple fiber under normal conditions are known. polypropylene staple fiber has superior moisture permeability and fast drying property, good combability and spinning performance, and can produce soft and tough fabrics. The fabric is light in weight, good in warmth, delicate in hand, comfortable to use, acid and alkali resistant. At the same time, it has the ability to dissolve quickly, good filling and sound insulation.

In the filling, in order to ensure uniform filling of the polypropylene short fibers in the regenerator and uniform porosity, the polypropylene staple fiber needs to be pretreated. Before the test, the polypropylene short fibers were divided into several parts, and vacuum drying was carried out to remove the components such as moisture which may affect the performance of the regenerator, and processed into several micelle structures according to the specifications of the regenerator. After the filling is completed, a copper wire mesh is added to both ends of the regenerator.
