Problems solved by technology

[0004] However, the female member of the prior art hook and loop fastener including the fastening layer using non-woven fabric does not have sufficient fastening force with the male member of the hook and loop fastener
In particular, in many cases, its shear stress or its peel strength is weak
Therefore, in disposable diapers and the like, for example, when wearing or after excretion, there is a problem of shifting and loosening

Embodiment 1

[0095]The raw non-woven fabrics in Table 1 were laminated and embossed using a patterned roll at a processing temperature of 160°C, a line pressure of 160 N / mm, and a processing speed of 10 m / min to provide a mother of a hook and loop fastener. member. The pattern used had an embossed portion with a width of 1 mm, was a square with a side of 10 mm, and was arranged so that the traveling direction of the nonwoven fabric formed an angle of 45° with the side. The nonwoven fabric used for the fastening layer is a nonwoven fabric produced by the "spunbond method", and the nonwoven fabric used for the physical layer is a nonwoven fabric produced by the "spunbond method". The results are shown in Table 1.

Embodiment 2

[0097] The raw non-woven fabrics in Table 1 were laminated and embossed using a patterned roll at a processing temperature of 160°C, a line pressure of 160 N / mm, and a processing speed of 10 m / min to provide a mother of a hook and loop fastener. member. The pattern used had an embossed portion with a width of 1 mm, was a square with a side of 10 mm, and was arranged so that the traveling direction of the nonwoven fabric formed an angle of 45° with the side. The nonwoven fabric used for the fastening layer is a nonwoven fabric of crimped fibers produced by the "hot air method" and having a core-sheath structure (sheath: polyethylene resin, core: polyethylene terephthalate resin). Cloth, and the non-woven fabric used for the physical layer is a non-woven fabric produced by the "spunbond method". The results are shown in Table 1.

Embodiment 3

[0099] The raw non-woven fabrics in Table 1 were laminated and embossed using a patterned roll at a processing temperature of 160°C, a line pressure of 160 N / mm, and a processing speed of 10 m / min to provide a mother of a hook and loop fastener. member. The pattern used had an embossed portion with a width of 1 mm, was a square with a side of 10 mm, and was arranged so that the traveling direction of the nonwoven fabric formed an angle of 45° with the side. The nonwoven fabric used for the fastening layer is a nonwoven fabric of crimped fibers produced by the "hot air method" and having a core-sheath structure (sheath: polyethylene resin, core: polyethylene terephthalate resin). Cloth, and the non-woven fabric used for the physical layer is a non-woven fabric produced by the "spunbond method". The results are shown in Table 1.

Abstract

Provided is a hook-and-loop fastener female member having an engaging layer using a nonwoven fabric, and exhibiting excellent engaging force with a hook-and-loop fastener male member. A hook-and-loop fastener female member according to the present invention and having an engaging layer capable of engaging a male member, wherein the engaging layer contains a nonwoven fabric comprising fibers, the density of the nonwoven fabric in the engaging layer is 5-110 kg / m<3>, and the diameter of the fibers is 15-60 [mu]m.

Description

technical field [0001] The present invention relates to female members of hook and loop fasteners. Background technique [0002] Various hook and loop fasteners are proposed for materials of articles such as sanitary products such as diapers or 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. [0003] In recent years, non-woven fabrics have been used for the fastening layer of the female member of many hook and loop fasteners used in hygiene products (in particular, disposable diapers, elastic bandages, masks, etc.) The layer that can be fastened ...
