Abstract
A disposable diaper includes a hook and loop fastener which includes: (i) a plurality of hook components, which are fixed in place on both lateral sides of a rear side of the disposable diaper, and (ii) a hook receiving component that is fixed in place at a belly side of the disposable diaper. The hook components are engageable with the hook receiving component to form a fixing member for putting the disposable diaper on a user. The hook receiving component includes a base material section having a target that is visible from a front surface side of the hook receiving component, and a plurality of loops which are fixed in place on a surface of the base material section. Each of the loops is formed of a non-crimp treated continuous filament yarn that is straight or slowly curved.
