Abstract
Disclosed is a wet wipe, for example, a dispersible wet wipe. The wet wipe may include a base sheet comprising short length fibers; a dispersible binding agent reinforcing the base sheet; and a wetting lotion. The dispersible binding agent may be configured to bind the fibers of the base sheet when the dispersible wiper includes liquid at an amount of at most 400 wt % from the weight of the base sheet and to disperse in excess water if the amount of the water exceeds 500 wt %.
Claims
exact text as granted — not AI-modified1 . A wet wipe comprising:
a base sheet comprising short length fibers; a dispersible binding agent reinforcing the base sheet; and a wetting lotion, wherein the dispersible binding agent is configured to bind the fibers of the base sheet when the dispersible wiper comprises liquid at an amount of at most 400 wt % from the weight of the base sheet and to disperse in excess water if the amount of the water exceeds 500 wt %, wherein the dispersible binding agent comprises microfibrillated cellulose, and wherein said dispersible binding agent is sprayed or printed on said base sheet after said base sheet is hydroentangled and before said base sheet is dried up.
2 . The wet wiper of claim 1 , wherein the dispersible binding agent is a non- adhesive agent.
3 . (canceled)
4 . The wet wiper of claim 1 , wherein the dispersible binding agent is an adhesive emulsion.
5 . The wet wiper of claim 3 , wherein the adhesive emulsion is selected from:
Vinyl Acetate based emulsion and Acrylic terpolymer emulsions.
6 . The wet wiper of claim 1 , wherein the dispersible binding agent is in an amount of 0.5-5 gram/square meter (gsm).
7 . The wet wiper of claim 1 , wherein the dispersible binding agent is in an amount of 1-2 gsm.
8 . The wet wiper of claim 1 , wherein the base sheet is a nonwoven sheet made from the short length fibers.
9 . The wet wiper of claim 1 , wherein the reinforced base sheet is comprised of fibers of a denier of no more than 5.0.
10 . The wet wiper of claim 1 , wherein the short length fibers comprise at least one of: bi-lobal (ribbon cross section) viscose, lyocell rayon polylactic acid (PLA) polymer fibers, cotton fibers and wood pulp.
11 . The wet wiper of claim 1 , wherein the base sheet has a weight of 30-100 gsm.
12 . The wet wiper of claim 1 , wherein the base sheet has a weight of 50-70 gsm.
13 . The wet wiper of claim 1 , wherein the short length fibers have maximum length of at most 15 mm.
14 . The wet wiper of claim 1 , wherein the diameters of the short length fibers are between 15 and 80 microns.
15 . The wet wiper of claim 1 , having a tensile strength of between 100 and 250 gm force/inch when the amount of wetting lotion added is 300 wt % from the weight of the base sheet.
16 . The wet wiper of claim 1 , wherein the wetting lotion includes at least one of: water, alcohol, acetone, perfume, reagent, soap, emulsifier, pigment, rheology modifier, aromatic oil, and a friction reduction agent.Join the waitlist — get patent alerts
