Abstract
A disposable diaper is disclosed which comprises a liquid-permeable surface sheet, a liquid-impermeable back face sheet and a water-absorbing layer disposed between said sheets, wherein water-absorbing shrinkable fibers, the length of which is reduced on contact with water to impart elasticity to the fibers, are fixed across the central portion of the diaper in the lengthwise direction of the diaper without being lapped over the water-absorbing layer and said water-absorbing layer is connected to said water-absorbing shrinkable fibers by cellulose fibers.
