Abstract
A method for increasing the thickness of a fibrous sheet including stretching the sheet beyond its relaxed length and returning the sheet to about the relaxed length, causing the sheet to have a second thickness greater than the first thickness. The sheet can be a wet-wipe. The wet-wipe includes an elastic layer and a fibrous layer, which increases in thickness when stretched then relaxed. The wet-wipe can be stored in a container which causes the wet-wipe to stretch as it is removed from the container.
Claims6
A system comprising:
- a dispenser;
- a plurality of wipes, each wipe being formed of a stretch-bonded laminate that includes a non-woven elastic layer bonded to a non-woven gatherable layer, the non-woven elastic layer including a layer of elastomeric meltblown fibers and a layer of substantially parallel elastomeric fibers that are bonded to the layer of elastomeric meltblown fibers, the wipes being stored within the dispenser such that the wipes become thicker as the wipes are individually removed from the dispenser;
- and
- a liquid absorbed by the plurality of wipes.
