An absorbent article which can effectively widen absorbing area of excretion liquid at a center portion of the absorbent article, is provided. Divided absorbent elements are formed dividingly on both of a center line. The divided absorbent elements are fixed on a back sheet at positions of compressed portions, and inner side end portions of the divided absorbent elements are taken as free ends. Upon use of a sanitary napkin, by bending the sanitary napkin in response to exertion of compressing force F from femoral parts, the divided absorbent elements are raised so that menstrual blood can be absorbed not only through inner surfaces but also through outer surfaces. Therefore, absorbing area can be greater than that of the conventional sanitary napkin, and side leakage can be successfully prevented.

The napkin body has an overlap region where the second projections lie on laterally opposite sides of the first projection.

The invention provides an anti-side leakage sanitary napkin, which includes a surface non-woven fabric and a bottom impermeable membrane disposed from the inside out. The surface non-woven fabric has a three-piece structure, the intermediate piece of surface non-woven fabric and the two-wing surface non-woven fabrics are sticked together, and the space between the intermediate piece of surface non-woven fabric and the bottom impermeable membrane is filled with a toilet paper coated wood pulp cellulose absorption core. The surface of the sanitary napkin provided by the invention is composed of 100% polylactic acid fiber or PLA/PBHV fiber hot blast nonwoven fabric. The polylactic acid fiber retains the original characteristics and does not cause any damage. As polylactic acid is formed by polymerization of lactic acid molecules as monomers and spinning, polylactic acid molecules with short molecular chains possibly exist on the fiber surface, so that the pH value of a polylactic acid non-woven fabric surface shows weak acidity and is consistent with that of human body skin. Also an odor removal function is provided. The lateral two pieces of non-woven fabrics have greater gram weight and thickness than the intermediate piece, and side leakage cannot be caused.

A coating apparatus includes modular interfaces and substrate receptors for accommodating various shapes and sizes of monolith substrates when coating layers are applied onto the monolith substrates. The monolith substrates are laterally surrounded by an elastically deformable sleeve that prevents lateral leakage of a vacuum out of the monolith substrate when a vacuum is applied to opposing ends of the monolith substrate, thereby eliminating needs for bulky vacuum chambers. The coating apparatus also includes valves and control apparatus that enable excess precursor liquid to be drained from monolith channels in-situ, without the use of additional spin-drying steps. Coating methods for using the coating apparatus are provided.
