Embodiment 1-11 and comparative example 1-3

[0130] The raw material non-woven fabrics shown in Table 1 and Table 2 were laminated and embossed using an embossing pattern roll at a processing temperature of 200° C., a linear pressure of 160 N / mm, and a processing speed of 20 m / min to provide Female component of hook and loop fasteners.

[0131] The embossing pattern used was figure 1 The arc-shaped embossing pattern shown in , and the embossing width, the maximum value of the distance between two adjacent embossings on a straight line along the MD direction (the distance L between the largest embossings), The embossed welded area ratio and the thickness of the welded portion formed by the embossed pattern are shown in Table 1 and Table 2.

Embodiment 12 and 13

[0133] The raw material nonwoven fabrics shown in Table 2 were laminated, and an ultrasonic welding machine (manufactured by Herrmann Ultrasonics, equipment name: MICROBOND (ULTRABOND 48 :20)) are embossed to provide the female member of the hook and loop fastener.

[0134] The embossing pattern used was figure 1 The arc-shaped embossing pattern shown in , and the embossing width, the maximum value of the distance between two adjacent embossings on a straight line along the MD direction (the distance L between the largest embossings), The embossed welded area ratio and the thickness of the welded portion formed by the embossed pattern are shown in Table 2.

Abstract

The object of the present invention is to provide a female member for a surface-contact fastener, and a surface-contact fastener and a sanitary product having the female member for a surface-contact fastener, which has an excellent fastening force. Fastening layer of non-woven fabric. The female member (100) for surface-contact fasteners of the present invention has: a fastening layer including fiber nonwoven fabric which can be fastened with a male member for surface-contact fasteners; and a layer for maintaining the physical properties of the fastening layer. The female member (100) for a surface contact fastener is characterized in that the flexibility index A represented by the formula (1) of the fastening layer is 0.004g ‑2 above. (1) A=1 / (P1×P2)P1: The maximum compressive load when the annular body is subjected to a compressive load from its axial direction and the annular body is deformed, the annular body is passed along a long strip of 25mm-width The length direction of the female member for the surface contact fixture is obtained by connecting the front end and the rear end with a stapler to form a ring shape; P2: the maximum when the aforementioned ring body is subjected to a compressive load from its width direction and the ring body is deformed Compression load.

Description

technical field [0001] The present invention relates to female members of hook and loop fasteners. The invention also relates to a hook and loop fastener comprising a female member of the hook and loop fastener of the invention. The invention also relates to a sanitary article comprising a female member of the hook and loop fastener of the invention. Background technique [0002] Various hook and loop fasteners are proposed for materials of articles such as sanitary products such as diapers and masks (for example, see Patent Documents 1 and 2). When the female member of the hook and loop fastener is used, for example, in a diaper, it is usually mounted on the front surface of the waist portion of the diaper and can be fixed to the side surface of the diaper with the male member of the hook and loop fastener (typically with a hook) closure, thereby completing a hook and loop fastener. Hook and loop fasteners are required to be able to be put on and off multiple times. [...
