摘要：
The present invention relates to a backsheet nonwoven fabric for diapers that is provided with a hook fastening function, and in a backsheet nonwoven fabric for diapers made of a thermoplastic polyolefin spunbond long fiber nonwoven fabric sheet, the backsheet nonwoven fabric has a basis weight of 16 to 38 gsm (g / m 2). ) To improve the shear strength, so it is possible to detach and attach it to the hook without a separate loop member. The thermoplastic polyolefin-based spunbond long fiber non-woven sheet is composed of yarns selected from polypropylene (PP) and polyethylene (PE) alone or by mixing them, and the back sheet non-woven fabric has a thickness of 0.15 to 0.4 mm by self-bonding between fibers. The formed fiber structure is used, and the shear strength of the backsheet nonwoven fabric is characterized by vertical strength (peel strength) of 1.0 to 2.8 N / inch and horizontal strength (shear strength) of 30 to 55 N / inch. In the back sheet non-woven fabric for diapers, which is provided with a hook fastening function according to the present invention, the process of manufacturing a separate loop member is omitted, thereby reducing the production cost of the product. Accordingly, the entire surface of the back sheet non-woven fabric forming the outer surface of the diaper acts as a roof sheet. Therefore, it is very convenient for consumers to wear diapers. In addition, since the backsheet nonwoven fabric is made of a thermoplastic polyolefin spunbond long fiber nonwoven fabric sheet designed to have a structure suitable for fastening with a hook member, there is almost no lint even during repeated use, and the detachability with the hook member is not only good. The soft texture of the nonwoven fabric surface has an excellent effect. In addition, the backsheet nonwoven fabric for diapers, which is provided with a hook fastening function according to the present invention, eliminates the process of transferring and assembling a vacuum member using a vacuu
