BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:

[0013] FIG. 1 is a cross-sectional view illustrating an absorbent pad 12 of the present invention;

[0014] FIG. 2 is a plan view illustrating a sanitary napkin according to an embodiment of the present invention; and

[0015] FIG. 3 is a cross-sectional view illustrating a straight type main body 10 in the sanitary napkin shown in FIG. 2, taken on line A-A in FIG. 2.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0017] As shown in FIG. 1, an absorbent article of the present invention may include an absorbent pad 12 consisting of a wood pulp web 12b and a cotton-based nonwoven fabric 12a laminated on the wood pulp web 12b, wherein the nonwoven fabric 12a includes a valley part continuously formed on a surface thereof in a length direction and arranged at a predetermined interval in a width direction thereof.

[0018] The absorbent article described herein may be a sanitary napkin, a diaper, etc.

[0019] The nonwoven fabric 12a included in the absorbent pad 12 may made of cotton, preferably, organic cotton. Preferably, the nonwoven fabric 12a is a pressed nonwoven fabric form fabricated by a compression process, so as to prevent leakage of menstrual fluid or urine in a width direction of the absorbent article.

[0020] As an embodiment of the absorbent article, a sanitary napkin according to present invention may include a straight type main body 10 and wing parts 20 formed on both sides of the straight type main body 10, respectively, as shown in FIG. 2.

[0021] The straight type main body 10 may include: (i) a bottom cover layer 11 made of a water-proof film; (ii) an absorbent pad 12 consisting of a wood pump web 12b and a cotton-based nonwoven fabric 12a laminated on the wood pulp web 12b; and (iii) a top cover layer 13 made of cotton and formed in a nonwoven fabric form.

[0022] As shown in FIGS. 1 and 3, the nonwoven fabric 12a included in the absorbent pad 12 may have a structure in which a valley part is continuously formed on a surface thereof in a length direction and arranged at a predetermined interval in a width direction thereof.

[0023] As shown in FIG. 3, channels C may be formed by the valley part between the nonwoven fabric 12a included in the absorbent pad 12 and the top cover layer 11. Therefore, the menstrual fluid does not leak in the width direction but flows in the length direction of the absorbent pad 12 to thus be absorbed therein.

[0024] The nonwoven fabric 12a is preferably a pressed nonwoven fabric fabricated by inter-mingling a web, which is a laminate of cotton mono fabrics, through needle-punching, followed by compression using a calendaring roller or the like.

[0025] The bottom cover layer 11 may be a synthetic resin film or a bio-degradable film, and the bio-degradable film is preferably used to minimize environmental contamination in consideration of disposal after use.

[0026] The nonwoven fabric 12a included in the absorbent pad 20 and the top cover layer 13 are made of a nonwoven fabric material including cotton only, thereby achieving excellent effects in preventing female diseases and excellent air-permeability, touch feel and comfortable fit, simultaneously.

[0027] According to the present invention, the valley part is continuously formed on the surface of the cotton-based nonwoven fabric 12a included in the absorbent pad 12 in the length direction and arranged at a predetermined interval in the width direction thereof, thus to form channels C in the length direction of the absorbent pad 12. As a result, leakage of the menstrual fluid in the width direction of the absorbent article may be effectively prevented.

[0028] Further, the absorbent pad 12 of the present invention includes the wood pulp web 12b as well as the cotton-based nonwoven fabric 12a, thereby rapidly absorbing the menstrual fluid and safely keeping the same therein.
