wherein the magnetic material has a size of 0.01 mm˜2 mm;
wherein a density of the pore of the solid particle is 10 3 number /cm 3 ˜10 12 number /cm 3 ; and
wherein a diameter of the pore of the solid particle is 10 nm˜100 μm.
2. The particle according to claim 1 , wherein, a surface layer of the solid particle is a pore layer, and an interior of the particle is of a solid construction.
3. The particle according to claim 1 , wherein, an interior of the solid particle is of a solid construction.
4. The particle according to claim 1 , wherein, a density of the solid particle is 0.3 g/cm 3 ˜1 g/cm 3 .
5. The particle according to claim 1 , wherein, the solid particle is in a shape of ball, cube, cylinder, oval or crescent.
6. The particle according to claim 1 , wherein, an average size of the solid particle is 1 mm˜10 mm.
7. The particle according to claim 1 , wherein, the polymer is selected from one of polypropylene, polyethylene, polystyrene, polyvinylchloride, ethylene-vinyl acetate, polyamide, or polyethylene terephthalate, or a mixture of two or a plurality of the aforesaid materials.
8. The particle according to claim 1 , wherein, open pores are distributed in an interior of the solid particle.
9. The particle according to claim 1 , wherein the magnetic material is a ferrous alloy.
10. A washing method comprising the following steps:
washing articles to be washed with the solid particle according to claim 1 ;
separating the articles to be washed from the solid particle;
rinsing the articles to be washed; and
drying the articles to be washed.
11. The method according to claim 10 , wherein, a neutral nonionic surfactant is used in the step of washing the articles to be washed with the solid particle.
12. The method according to claim 10 , wherein, in the step of washing the articles to be washed with the solid particle, a mass ratio of the articles to be washed to the solid particle is 1:0.5˜1:5.
13. The method according to claim 10 , wherein, the step of separating the articles to be washed from the solid particle is conducted in a magnetic field.
