Preparation method of hollow polyester fiber with controllable hollowness

The invention relates to a preparation method of hollow polyester fiber with controllable hollowness. In the method, two screw extruders are used for respectively feeding materials for a cover/core spinneret plate assembly, a cover layer which is made of polyester and water-solubility polyester and a core layer which is water-solubility polyester are melted in a certain proportion for composite spinning, and then postprocessing processes are carried out to prepare polyester staple fiber; and fabric made of the obtained fiber is treated with an alkaline solution to remove the water-solubility polyester from the core layer and the cover layer, and thus the fiber is of a hollow structure, and lots of micropores, trenches and through holes are formed on inner and outer surfaces of the fiber at the same time. Since hollow holes are formed after the core layer is removed through melting, deformation of hollow holes, caused by extrusion in a stretching process in the preparation of hollow fiber spun with a profile hole spinneret plate spinning method, can be avoided, and hollowness is reduced; and moreover, through the change of the proportion of raw materials for spinning, the polyester fiber with controllable hollowness being 5-75% is prepared.
