ABSTRACT:
A method for producing a non-woven fabric which comprises bonding webs comprising a hydrophilic or hydrophobic non-shrinkable fiber and a heat-shrinkable fiber (e.g., a dry heat-shrinkable fiber and a wet heat-shrinkable fiber) partially or in a pattern with a binder, heating rapidly the bonded webs and thereby shrinking the webs to give a bulky and soft non-woven fabric having high water absorption properties; when the web comprises a predominant hydrophilic fiber and a wet heat-shrinkable fiber, the web is preferably subjected to a pre-wetting prior to the print bonding.
