ABSTRACT:
The invention provides a process for producing a highly absorbent, high strength wiper, which comprises the steps of providing a bonded nonwoven web selected from the group consisting of spunbond fiber webs and staple fiber webs, stretching the nonwoven web by applying a stretching tension in at least one direction, aperturing the nonwoven web while maintaining the stretching tension, and relaxing the apertured web, thereby returning the apertured nonwoven web substantially to its pre-stretched dimensions, wherein the process is conducted at a temperature below the softening point of the nonwoven web. The invention also provides a nonwoven wiper produced in accordance with the production process.
