A laminate (6) is prepared by superposing a fibrous web (1a), (1b) containing fibers comprising polyethylene terephthalate on one side or both sides of a net-form sheet (4); water needling the fibrous web (1a), (1b) to entangle the fibers of the fibrous web (1a), (1b) with each other, and also to entangle the fibers of the fibrous web (1a), (1b) with the net-form sheet (4); and then, blowing hot air having a temperature above the glass transition temperature (Tg (° C.)) of the polyethylene terephthalate and below “Tg (° C.)+70° C.” to the laminate (6) by through-air technique. Preferably, after preparing the laminate (6) by entangling the fibers of the fibrous web(s) (1a), (1b) with the net-form sheet (4), the laminate (6) is dried with hot air; and then hot air is blown to the laminate (6) by through-air technique.
