Fibrous support intended to be impregnated with liquid
Fibrous support intended to be impregnated, the fibers of which are formed 100% of cellulose fibers, characterized in that it presents, before creping or embossing, a wet traction strength of over 2.4 N/15 mm in the cross-machine direction, a water absorption capacity of at least 300% and contains less than 2% dry wet strength 10 agent in comparison with the dry weight of the fibers.
1. Method of manufacturing a moist wipe,
the method comprising the steps of:
preparing a mixture comprising water, refined long cellulose fibers having an average length of between 1.2 mm and 1.5 mm, non-refined cellulose or cellulose-based fibers having an average length of between 0.5 mm and 0.72 mm, and wet strength agent,
bringing said mixture to the headbox of a paper machine,
forming a sheet on a draining wire of the paper machine,
drying the sheet directly at an outlet of the draining wire, without any previous mechanical pressing, and
impregnating the sheet with liquid for forming a moist wipe.
2. Method according to claim 1 , further comprising adding cellulose-based fibers in said mixture of cellulose fibers and the wet strength agent.
3. Method according to claim 1 , wherein said cellulose fibers include short and long fibers, of which the long fibers are refined before the sheet formation.
4. Method according to claim 1 , further comprising refining the long fibers to above 35° Shopper-Riegler.
5. Method according to claim 1 , further comprising refining the mixture of fibers before forming the sheet.
6. Method according to claim 1 , further comprising drying the sheet by through-air.
7. Method according to claim 1 , wherein a forming speed is at least 400 m/min.
8. Method of manufacturing a moist wipe,
the method comprising the steps of:
refining long cellulose fibers to above 35° Shopper-Riegler, said long cellulose fibers having an average length of between 1.2 mm and 1.5 mm,
preparing a mixture comprising water, the refined long cellulose fibers having an average length of between 1.2 mm and 1.5 mm, non-refined cellulose or cellulose-based fibers having an average length of between 0.5 mm and 0.72 mm, and wet strength agent,
bringing said mixture to the headbox of a paper machine,
forming a sheet on a draining wire of the paper machine,
drying the sheet directly at an outlet of the draining wire, without any previous mechanical pressing, and
impregnating the sheet with liquid for forming a moist wipe.
9. Method according to claim 8 , further comprising adding cellulose-based fibers in said mixture of cellulose fibers and the wet strength agent.
10. Method according to claim 8 , wherein said cellulose fibers include short and long fibers, of which the long fibers are refined before the sheet formation.
11. Method according to claim 8 , further comprising refining the mixture of fibers before forming the sheet formation.
12. Method according to claim 8 , further comprising drying the sheet by through-air.
13. Method according to claim 8 , wherein a forming speed is at least 400 m/min.
