文摘Filtering materials are chosen according to the mechanism of blood filtration and mathematics model, then the material is treated with amine and alkali solution. There is cooperation and synergism between alkali and amine, and the actions are realized in three stages. After modification the material treated has accessibility groups NH 2 , and slits appeared in the surface of fiber, so the wettability of materials is improved distinctly; the diameter and aperture of fiber have no changes basically.
