FIG. 7 is a perspective view of the soft and minute opening plastic sheet 1 1 0 disclosed in Japanese Patent Application Laid-Open No. 6 2-5 7 5 5 1. The plastic sheet 1 10 is a surface sheet suitable for disposable diapers, etc. The surface of the plastic sheet is formed with a plurality of cylindrical protrusions 1 2 0, and a small opening 1 2 5 is formed on the top of the protrusions 1 2 0. The sheet 1 1 0 is described as being soft and showing a cloth-like touch. Fig. 8 is a perspective view of a diaper 2 0 for physiological use disclosed in Japanese Patent Application Laid-Open No. 7-3 2 8 0 61. The surface sheet 2 1 0 of the physiological diaper 2 Q 0 is made of a non-woven fabric 2 1 1 and a plurality of strip-shaped plastic sheets 2 1 2 bonded to the non-woven fabric 2 1 1 above, and the strip-shaped plastic sheet 2 1 2 It is a longer direction extending parallel to each other in the physiological diaper 200. The physiological diaper 2 0 0 can conceal the dirt caused by menstrual blood by using plastic sheet 2 1 2. One of the methods of using the above-mentioned known minute opening plastic sheet 1 10 as a surface sheet of a physiological diaper to conceal soiling caused by menstrual blood located in a liquid-absorbent core is to use inorganic particles such as calcium carbonate or barium sulfate. Fill the sheet 1 1 0. In order to increase the hiding power, it is sufficient to increase the particle charge. However, only increasing the filling amount may cause problems such as a decrease in the strength of the sheet or a larger thickness contact range during the production of the sheet. Therefore, it is necessary to increase the thickness of the sheet used to eliminate such problems. Only in this way may the sheet become highly rigid and lose the cloth-like feel, and even the cylindrical convex shape 1 2 0 is lacking in softness. The above-mentioned Japanese Unexamined Patent Publication No. 7-3 2 8 0 6 1 refers to the surface sheet 2 10 formed by a flatter sheet such as a non-woven fabric, although it is called a band-shaped plastic sheet * (please read the precautions on the back before filling out this page). -Line · Printed by the Consumers 'Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs This paper is printed in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) -4- Printed by the Employees' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Description of the invention (2) 2 1 2 can improve the concealment force, but the plastic sheet with the cylindrical convex shape 120 as mentioned above does not demonstrate the utilization method of the plastic sheet. The present invention refers to these conventional technologies, and it is an object to provide a soft skin touch and high hiding power to a disposable liquid-absorbent article, for example, using a liquid-permeable sheet as a surface material.

The description of the invention (6) is more appropriate, and it is better to set it to more than 1/2. This band-shaped material part i 6 can be obtained by extruding thermoplastics into a strip shape and supplying film-like material @ {分 17, except that the cross-sectional shape is not limited to the rectangle shown in the figure. Round or oblong. The band-like material portion 16 should be set to enable the menstrual blood absorbed by the core 4 in the iS M cloth 1 in FIG. 1 to prevent the surface sheet 2 from being seen through. The jg needs to be able to improve the concealment of the surface sheet 2 and function . This kind of band-like material, Douyin 16 is added with inorganic fillers such as titanium oxide and barium magnetization, and sometimes dyed with pigment. These added amounts can be added in a range that does not cause obstacles to the extrusion molding of the band-like material portion 16. When the inorganic filler is added in a large amount, the strip-shaped material portion with a narrower width and a thicker thickness is 16 to 6 and the film-shaped material portion with a wider width and a thinner thickness is more easily extruded. The thickness of the part 16 is uneven, and it also has little effect on the function of the surface sheet 2. Therefore, the use of such a strip-shaped material part 16 can easily improve the hiding power of the surface sheet 2. When the surface sheet 2 is viewed from above, the content of the inorganic filler per unit area of the band-like material portion 16 is higher than the content of the film-like material portion 17. It is preferable that the former content is at least the latter content. One to three times is more appropriate. The band-like material portion 16 also contributes to the improvement of the tensile strength in the γ direction of the film-like material portion 17. The flat portion 18 of the film-like material portion 17 has a thickness of 0.5 mm and a width W of 0.3 mm to 5 mm between the openings 19 and 19. Most of the openings 19 extend longer in the Y direction, and it is preferable to have a width W2 of 305 to 5 mm and a length of at least 1.5 times the width. s I --------- 1 —Equipment (Please read the precautions on the back before filling out this page) Order.

Although it is not easy to visually confirm each of the erected portions 2 2, when the erected portions 2 2 are majority, the surface of the surface sheet 2 appears to be fluffed. Moreover, the upright part 22 will cause incident light of the surface sheet 2 to be randomly reflected, which can eliminate the surface gloss often seen in the plastic sheet. In general, adding a large amount of inorganic filler to the film of the film-like material part 17 will make the film difficult to manufacture. Therefore, the surface sheet 2 does not obtain a high concealing force with respect to the dirty core portion by the film-like material portion 17, but obtains the concealing force by the belt-like material portion 16, and the film-like material portion 1 7 Promote the appearance and skin feel of the surface sheet 2 and use the two parts 16 and 17 of the temple respectively. The non-woven fabric layer 12 contains at least 70% by weight of thermoplastic synthetic fibers.

The first fabric 101, the second fabric 102, and the third fabric 103 The paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) -14- -------------- -(Please read the precautions on the back before filling this page) --line- 523403 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 ___ Description of the invention (12) If necessary, the project can be illustrated as appropriate Apply a waterproof or other surface treatment to the location. If the first fabric 101 is a film that is uniaxially stretched in the supply direction, it may be easily formed as a hole by a columnar water flow. The first fabric 101 uses a thickness of 0 · 001 ~ 0 · 05mm, and the third fabric 102 uses a thickness of 0 · 01 ~ 〇 · 3mm and a width of 0 · 1 ~ 4mm. The third fabric 1 0 2 uses a weight of 5 to 50 g / m2. In the process of FIG. 6, the first treatment area 1 2 3 is omitted, and the high-pressure columnar water jet is sprayed only in the second treatment area 1 2 7, thereby eliminating the need to make the second composite fabric 1 7 and the first composite fabric 1 0 6 为 组合 片 1 0 8. Due to this manufacturing method, it is difficult for the columnar water flow to directly affect the first fabric 101, which causes the first fabric 101 to easily generate narrow-width openings and more bridging portions. The composite sheet 108 was appropriately dried before being taken up. In the process of FIG. 6, the second composite fabric 107 can also be taken out from the illustrated process, and the composite fabric 107 can be used as the surface sheet 2. At this time, the surface sheet 2 has hardly formed a standing portion 22 at the edge portion 21 of the opening 19. The process sequence of FIG. 6 is changed, and a plurality of straps 1 1 6 which are the first fabric 1 0 1 are ejected from the first extruder 1 2 1, and this is joined to the fiber aggregate of the second fabric 1 0 2 Instead, it can be set as the first composite fabric 104. And the third fabric 103 which is a thin film is ejected from the second extruder 1 2 2 and bonded to the first and second fabrics 104 and 102 which form the first composite fabric 104. A second composite fabric 106 was obtained. After the second composite fabric 10 6 is processed by the first and second processing areas 1 2 3 and 1 2 7, it is a composite sheet 108 having the structure shown in FIG. 5.
