Problems solved by technology

[0006] Moreover, when the hardness of the ribs surrounding the holes is not sufficiently strong, the ribs will be crushed when the body pressure is applied to the surface cover, or when the absorber absorbing body fluids expands, causing the surface to be damaged. The gap between the cover and the absorber is narrowed, and the body fluid seeps from the absorber to the outside of the cover through the holes in the cover, making it unable to fully function in the early stage

Abstract

To provide the subject sheet improved in skin touch with reduced wet feel due to body fluid while retaining its performance and touch feel and capable of preventing the body fluid from oozing from the absorptive article via the open holes onto the outer surface thereof. The objective surface sheet consists of a nonwoven fabric sheet formed by fusing thermoplastic synthetic fibers. On the surface of this sheet, many ridges and flutes are alternately arranged so as not to represent a plane, the ridges are projectedly curved, while the flutes recessedly curved. Each of the flutes has an open hole with a rib extending from the surface of the sheet to the back surface , and the rib is harder than the other parts.

Description

technical field [0001] The present invention relates to a surface cover of an absorbent article, more specifically, it is the most surface cover of a sanitary napkin or a diaper that is in direct contact with the skin of a human body. It can not only maintain its performance and feel, but also A three-dimensional surface cover of an absorbent article that prevents absorbed body fluids such as blood and urine from flowing out from the wearing article. Background technique [0002] Conventionally, porous films or nonwoven fabrics have generally been used as surface covers for absorbent articles such as sanitary napkins and diapers. [0003] In the case of using a porous film as a surface cover cloth, as disclosed in Japanese Patent Publication No. 57-17081 and Japanese Patent Laid-Open No. 60-68928, holes are provided on the surface of the plastic film, and blood or blood is passed through the holes. The method of absorption of body fluids such as urine. [0004] However, th...
