Abstract

The present invention relates to a dry wipe, a biodegradable packaging containing the dry wipe, an arrangement comprising the dry wipe and a dispenser container, and a process for providing a wet wipe. The dry wipe comprises a wipe substrate impregnated with at least one additive to be activated by addition of water, wherein the at least one additive is selected from the group consisting of a biocide, a surfactant and a care product, wherein the wipe substrate is configured for allowing a distribution of liquid, even when the dry wipe is stacked in a dispenser container.

Claims (26)

1 . A dry wipe comprising a wipe substrate impregnated with at least one additive to be activated by addition of water, wherein the at least one additive is selected from the group consisting of a biocide, a surfactant and a care product, wherein the wipe substrate is configured for allowing a distribution of liquid, even when the dry wipe is stacked in a dispenser container, wherein the wipe substrate is a biodegradable non-woven fabric comprising biodegradable fibers and pulp fibers, wherein at least a part of the biodegradable fibers is entangled with each other, wherein at least a part of the pulp fibers is covalently bonded to each other by at least one of the group consisting of a biodegradable binder, a biodegradable wet-strength agent and a biodegradable binder fiber, wherein the non-woven fabric is non-dispersible in water.

2 . The dry wipe according to claim 1 ,

wherein the biodegradable fibers comprise cellulosic fibers.

3 . The dry wipe according to claim 1 , wherein the biodegradable fibers comprise regenerated cellulose fibers selected from the group consisting of viscose and lyocell.

4 . The dry wipe according to claim 1 ,

wherein the pulp fibers are comprised in an amount of from 20 to 90 wt.-% based on the total weight of the non-woven fabric, and/or

wherein the biodegradable fibers are comprised in an amount of from 10 to 80 wt.-% based on the total weight of the non-woven fabric.

5 . The dry wipe according to claim 1 , wherein at least a part of the pulp fibers is bonded to each other by a biodegradable binder.

6 . The dry wipe according to claim 5 , wherein the biodegradable binder is selected from the group consisting of chitosan, modified starch, cellulose derivatives, and protein based binders.

7 . The dry wipe according to claim 6 , wherein the biodegradable binder comprises a blend of carboxymethylcellulose and citric acid.

8 . The dry wipe according to claim 1 , wherein at least a part of the pulp fibers is bonded to each other by a biodegradable wet-strength agent.

9 . The dry wipe according to claim 8 , wherein the biodegradable wet-strength agent is selected from the group consisting of chitosan, modified starch and cellulose derivatives.

10 . The dry wipe according to claim 1 , wherein at least a part of the pulp fibers is bonded to each other by a biodegradable binder fiber.

11 . The dry wipe according to claim 10 , wherein the biodegradable binder fiber comprises a bicomponent fiber.

12 . The dry wipe according to claim 1 , wherein the at least one additive comprises a biocide.

13 . The dry wipe according to claim 12 , wherein the biocide comprises at least one of benzoic acid and a salt thereof.

14 . A biodegradable packaging containing the dry wipe according to claim 1 .

15 . The biodegradable packaging according to claim 14 , wherein the biodegradable packaging is made of a biodegradable material.

16 . The biodegradable packaging according to claim 15 , wherein the biodegradable packaging is made of glassine paper.

17 . An arrangement comprising:

the dry wipe according to claim 1 , and

a dispenser container adapted to accommodate the dry wipe and adapted to allow a distribution of a liquid so as to convert the dry wipe into a wet wipe, wherein the dispenser container has at least one opening adapted to allow addition of the liquid and adapted to allow dispensing of the wet wipe.

18 . A process for providing a wet wipe, the process comprising:

placing the dry wipe according to claim 1 into a dispenser container, and

adding a liquid containing water into the dispenser container such that the liquid comes into contact with the dry wipe.

19 . The process for providing a wet wipe according to claim 18 , wherein the dispenser container is adapted to accommodate the dry wipe and adapted to allow a distribution of a liquid so as to convert the dry wipe into a wet wipe, wherein the dispenser container has at least one opening adapted to allow addition of the liquid and adapted to allow dispensing of the wet wipe.
