PURPOSE:To obtain the subject then sheet, containing water absorbing fiber having fresh water absorptivity and heat bonding fiber, having a high tenacity and shape stability of the sheet, good in handleability and excellent in water absorption rate and absorptivity and useful as paper diapers, etc. CONSTITUTION:The objective highly water absorbing sheet, composed of 20-80wt.% water absorbing fiber having >=100 times fresh water absorptivity and 80-20wt.% other fibers, containing >=20wt.% (based on the nonwoven fabric) heat bonding fibers as the other fibers in the aforementioned nonwoven fabric, interstices between the water absorbing fiber and/or other fibers being bonded by at least partially softening or melting the heat bonding fibers. Furthermore, the above-mentioned water absorbing fiber is preferably a polycarboxylic acid- based fiber or isobutylene/maleic anhydride copolymer-based fiber having >=200 times fresh water absorptivity. |
