The invention provides an anti-electromagnetic wave natural fabric manufacturing device and technique. The manufacturing device comprises a shell which can be opened and closed, wherein an unwinding roller and a winding roller are arranged in the shell; base cloth passes through the surface of a sputtering platform; the surface and bottom of the sputtering platform consist of metal nets and cover bodies; an exhausting channel and an air inlet channel are arranged on the shell; the cover bodies communicate with the exhausting channel; a base parallel to the sputtering platform is arranged at the other side of the base cloth; and a sputtering target is arranged on the base. The anti-electromagnetic wave natural fabric manufacturing device has the beneficial effects that moisture in fibers in the base cloth is solidified and sublimated by vacuum condensation of the base cloth, so that cavities are formed in the fibers; and the entry degree of coating films in the cavities is controlled or holes are formed in parts, corresponding to the coating films, of the cavities by using opposite force generated when residual moisture in the cavities is evaporated, so that the base cloth coated with the films has an anti-electromagnetic wave property and good air permeability and moisture absorption.
