发明名称 tecido de prensa estratificado.
摘要 <p>A stratified press fabric for the press section of a paper machine includes a base fabric in the form of an endless loop. A first staple fiber batt material is attached to the outer side of the base fabric by needling. A fine fabric covers the first staple fiber batt material, and a second staple fiber batt material is attached to the fine fabric by needling. The fibers making up the second staple fiber material are finer, that is, of smaller diameter or denier, than the fibers making up the first staple fiber material. The fine fabric prevents the coarser fibers of the first staple fiber batt material from being needled therethrough to mix with the finer fibers of the second fiber batt material.</p>
