The present invention relates to an absorbent article which is excellent in softness and excellent in touch feeling on the surface sheet and the skin contact surface of the absorbent article having excellent flexibility. The pant 20 shown in Fig. 1 is an embodiment of the absorbent article of the present invention, and has a liquid-permeable surface sheet, a liquid-impermeable back sheet 30, and a liquid-repellent absorption between the two sheets. The body 4〇« is further provided with a fixing agent such as an adhesive on the outer surface of the back sheet 3, and a release sheet (not shown) for protecting the fixing agent before use. The surface sheet 1 of the panty liner 20 is an embodiment of the surface sheet of the absorbent article of the present invention. As shown in FIG. 2, it is composed of a single layer of spunlace nonwoven fabric, and the form of the non-woven fabric is mainly It is maintained by the interlacing of the constituent fibers. Further, a softening agent is applied to the spunlace nonwoven fabric. Although the softening agent may be applied over the entire thickness direction of the spunlace nonwoven fabric, it is preferable that the application portion is directed toward the user: the skin side (hereinafter referred to as the skin contact surface side) or the orientation. The side of the side opposite to the side of the skin side of the user (hereinafter referred to as the non-skin contact side). The softening agent may be applied to either the skin contact surface side or the non-skin contact surface side to improve the softness of the surface sheet, but the softening agent is mainly applied to the non-skin contact side, and the softening agent itself When the hydrophilicity is low, the liquid absorption from the skin contact surface side can be prevented from being lowered. On the other hand, in the case where the softening agent is mainly applied to the side of the skin contact surface, the sample of the discharge 邛 configuration of 97751.doc 1355261 is a sample having a length of 5 〇 mmx and a width of 3 ounces. Further, in the case where the line pattern is applied, the applied softening material may be applied to the skin contact surface side or the non-skin contact surface side, but it may be suitably used even if it is not biased in one of them. Further, the surface sheet of the present invention may prevent the liquid permeability from being impaired, and may be applied irregularly (non-pattern coating) from the viewpoint of improving the flexibility. In particular, it is preferable to mix the portion where the softening agent is applied at a high concentration on the both sides or the single side of the surface sheet, and the portion where the softening agent is applied at a low concentration, and the "two low J" means one side. The level of comparison with other parties is relative level. - a particularly ideal type, a portion where the softening agent is applied at a high concentration, and a low concentration portion coated with a concentration lower than the high concentration portion, And a portion in which the softening agent is hardly distributed in a mosaic form. Thus, the portions of the various sizes are mixed in a mosaic form at various coating concentrations, and the soft portion (the portion having a higher coating concentration) It is particularly preferable that the softness is easy to spread the entire sheet and the portion which is easy to absorb liquid (the portion where the softener is not sufficiently distributed) can be distributed to the whole, so that the liquid absorption and the softening effect can be achieved at the same time. Usually, impregnation, coating, flexographic printing, etc. are applied, but the non-woven fabric is rolled on one side by the pro-belt, and the light touch method of the (4) process is not required. Therefore, it is most desirable. In this case, the rolling pattern can form a random mosaic pattern when executed, so it is advantageous: the effect of any situation is to try to form an uneven hook on the plane 9775I.doc 526 force 5261 The softener distribution is 'regardless of whether it is applied from the back or the surface, and it is applied uniformly to the thickness direction or to the uncoated layer. Moreover, the coated portion is on the skin contact side and the non-skin contact side. It is also applicable to the one which is not biased to one side. The softening agent is from 3% to 3% of the unit weight of the surface sheet, especially 0.1% to 0.5%, which is a sufficient adhesion amount which can be perceived to be improved in touch, and is low in cost. It is quite desirable. The amount of softening agent applied can be measured by the following methods: (1) In the process management, if you can know the weight per unit area of the spunlace produced by the spunlace method (weighing, g/m2) With the production speed and the concentration of the liquid medicine produced, the amount of adhesion can be calculated from the consumption of the liquid per unit time. (2) On the product (sheet), if you can understand the type of softener that is applicable, you can analyze the type of softener. Coating amount and coating For example, in the case of using a tanning softener, the amount of coating and the state of application can be measured by Si-ray X-ray analysis of the sheet, or the average adhesion per unit area can be determined by NMR analysis after extracting a suitable solvent. The amount of the softening agent applied is such that when the softening agent is applied by a pattern (including an irregular mosaic pattern coating), the average coating amount can be obtained by NMR analysis of the extracted solvent. The average concentration is known to be 'and the amount of adhesion distribution can be known by the (1) imaging situation obtained by, for example, fluorescent X-ray analysis. The surface sheet of the present invention is, for example, in the process of spunlace non-woven fabric, which is manufactured by a spunlace method. After the fiber web is not woven, the softening agent is applied and then dried. The effect of the present invention is more remarkable when the 9775I.doc or 嫘f yarn is the main body.睹, A 喷 ^ 不 不 不 之 不 不 以 以 不 不 A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A , ΡΡ fiber, PET / polyethyl (PE) composite fiber, etc. For this purpose, the amount of hydrophobicity of the mixture is in the weight of the fiber, 2 to 20% by weight y and cotton and / or The blending amount of the silk yarn is preferably about 80 to 98% by weight based on the total weight I of the constituent fibers. It is more preferable when the hydrophobic synthetic fiber is hydrophilized, and the surface sheet (although depending on the absorption) The composition of the article '2' refers to the case where the spunlace method is a nonwoven fabric having a sufficient strength of g/m or more, and the bulk softness is preferably from 19 to 29 4 and the heart is preferably from 3.8 to 14 In particular, when the constituent fibers of the spunlace non-woven fabric are cotton or silk, the softness of the bulk is preferably 2, 9 to 19. "N, more preferably 4.9 to 14.7 cN. The softness can be measured by the following method: <Measurement of bulk softness> For the surface sheet, cut out five rectangular samples of the winding direction (MD direction) of 15 mm×width (CD direction) of 3 mm. The length of each sample was about 5 mm in the longitudinal direction. A cylinder having a diameter of 45 mm is formed, and staples are used at the upper end (the upper end in the cylinder axis direction) and the lower end of the overlapped ends (for example, a pin of n〇1〇_1m made by MAX Co., Ltd.) The measurement sample of the cylindrical shape is obtained by fixing. Further, the direction of the staple is parallel to the circumferential direction. 97751.doc 12 1355261: The measurement of the weight of the needle π "Initial sample width: 3 安置 安置 安置 = = = = = = = = In the case of the company's Oriental Society, "RTA,", the measurement is made by the use of the force = m to the circular plate, which is shown in the direction of the axis of the cylinder (the width of the sample) at a compression speed of 1 G _ / min. The maximum load is performed on the five samples, and the average value is taken. 匕 The present invention is limited to the above-mentioned implementation, and various changes can be made within the scope of the present invention. The absorbent article of the present invention can also be absorbed outside the underwear lining! Other examples of the use of the material in contact with the skin of the user include a sanitary napkin, a disposable diaper, an adult Si pants, a breast expansion absorbent pad, etc. Further, the constituent material of the absorbent article of the present invention is other than the surface sheet. It is not particularly limited. For example, as the constituent materials of the absorbent body and the back sheet of the panty liner, materials conventionally used in such articles can be used: for example, as an absorbent body, pulp fibers or heat can be used. A fiber assembly (web, non-woven fabric, etc.) composed of a plastic fiber or an absorbent body in which a water-absorbent polymer is held in a layered or dispersed state, and as a back sheet, polyethylene, polypropylene, polyvinyl acetate, poly A film of a thermoplastic resin such as an ester or a water-repellent spunbonded fabric non-woven fabric, a spunbonded fabric, a non-woven fabric of a multi-layer structure of a spunbonded nonwoven fabric, a spunbonded fabric, and the like. Further, in the present invention, the effect of the softening agent is disclosed as the present invention which is effectively applied to the spunlace nonwoven fabric. In order to further improve the softness, a calender roll may be added after the spunlace method is formed or after the spunlace method is formed, to apply the crucible 9775l.doc 13 丄355261. As described in detail above, it is possible to provide a surface sheet having sufficient strength and excellent flexibility in accordance with the present invention. According to the absorbent article of the present invention, it is possible to provide an absorbent article which is soft in skin contact and excellent in touch.
