Abstract
Disclosed are woven or hydroentangled non-apertured cleaning sheets having non-random recessed and raised regions. Optionally, the sheets can comprise a scrim material or additives to improve adhesion. Also disclosed are cleaning implements comprising a handle and the described non-apertured cleaning sheets. Methods of using the sheets, articles of manufacture having instructions to the product benefits of the non-apertured cleaning sheets, and process of making the sheets are also disclosed.
Claims46
A macroscopically three-dimensional non-apertured cleaning sheet comprising a structure consisting of materials selected from the group consisting of woven materials and nonwoven materials, having a working face and a back face, wherein the working face comprises nonrandom raised regions and recessed regions.
A non-apertured cleaning sheet that reduces the level of airborne materials in the atmosphere, relative to a cleaning sheet that has a random macroscopic three dimensional character.
A non-apertured cleaning sheet that reduces the level of particulate soils on surfaces, relative to a cleaning sheet that has a random macroscopic three dimensional character.
A cleaning implement comprising:
- a. a handle;
- and
- b. a removable non-apertured cleaning sheet that provides greater reduction in the level of airborne materials in the atmosphere, relative to other products and practices for similar cleaning purposes.
A cleaning implement comprising:
- a. a handle;
- and
- b. a removable, non-apertured cleaning sheet that provides greater reduction in the level of particulate soils on surfaces, relative to other products and practices for similar cleaning purposes.
A process for making a non-apertured cleaning sheet having a non-random macroscopic three dimensional character comprising the step of hydroentangling fibers on a patterned forming belt.
A non-apertured cleaning sheet comprising a structure made from fibers having a denier of greater than about 2.0 denier.
A non-apertured cleaning sheet comprising a structure made from fibers having two or more distinct denier measurements.
A non-apertured cleaning sheet comprising a working surface with a total pore volume of greater than about 750 gsm.
A non-apertured cleaning sheet comprising a working surface which has pores, wherein greater than about 15% of the pores volume is contained in pores having a pore size of greater than about 70 microns.
A non-apertured cleaning sheet comprising a working surface which has pores, wherein greater than about 7.5% of the pore volume is contained in pores having a pore size of from about 70 microns to about 700 microns.
