Abstract
A nonwoven material suitable for use as a wet wipe substrate is disclosed. The nonwoven material comprises thermoplastic fibers and is provided with a pattern of embossments that join at least a portion of the thermoplastic fibers. When the material is treated with a cleaning lotion to provide a wet wipe, the wet wipe has a wet CD modulus that is greater than about 25 N/m and less than about 80 N/m.
Claims14
A wet wipe comprising:
- a) a cleaning lotion comprising an aqueous emulsion including an emollient and an emulsifier;
- and
- b) a nonwoven substrate comprising thermoplastic fibers and viscose fibers, said substrate having a basis weight less than about 55 grams/m2 wherein said substrate is calender-embossed with embossments to form an emboss pattern, wherein said emboss pattern has a bond area greater than about 12% and less than about 25%, and wherein said embossments serve to join at least a portion of said thermoplastic fibers so as help provide said substrate with a wet CD modulus that is greater than about 25 N/m and less than about 70 N/m.
A wet wipe comprising:
- a) a cleaning lotion comprising an aqueous emulsion including an emollient and an emulsifier;
- and
- b) a nonwoven substrate comprising thermoplastic fibers and viscose fibers, said substrate having a basis weight of less than about 55 grams/m2 wherein said substrate is calender-embossed with embossments disposed along parallel lines to form a repeating emboss pattern of diamonds, wherein said emboss pattern has a bond area greater than about 12% and less than about 25%, and wherein said embossments serve to join at least a portion of said thermoplastic fibers so as help provide said substrate with a wet CD modulus that is greater than about 25 N/m and less than about 70 N/m.
