Description

Face fastening member

The present invention relates to a face fastener member.

Various surface fasteners have been proposed as members of articles such as sanitary articles such as diapers and masks (see, for example, Patent Documents 1, 2, etc.). When the gusset member is used, for example, in the case of a diaper, it is usually attached to the front surface of the waist portion of the diaper, and the male member of the face fastening member (representatively having a fastening hook) fixed to the side of the diaper is engaged. This becomes a surface fastener. The opposite fasteners are required to be removed several times.

In recent years, the fastening layer of the female member of the face fastener used in sanitary articles (especially disposable diapers, elastic bandages, masks, etc.) is large (the layer of the hooks of the snap members of the male members of the face fasteners can be fastened) Most use non-woven fabrics.

However, in the prior art, the surface fastener member having the fastening layer of the non-woven fabric is mostly insufficient in the fastening force with the male member of the surface fastener member, especially the shear stress is low or the peel strength is weak, in a disposable diaper or the like. There is a problem that the displacement is loose during wearing or excretion.
