Partitionable paper towel
A paper towel product that can be capably separated from the paper towel roll as a full sheet, a half sheet or a quarter sheet is disclosed. A method of making a paper towel with machine direction perforations is also disclosed.
1. A partitionable wiper product comprising:
a base sheet having a SAT absorbency of between about 300 g/sq. meter and about 1300 g/sq. meter;
wherein the base sheet has a basis weight of at least 20 g/sq. meter;
wherein the wiper product comprises at least one MD perforation line; and
wherein the ratio of the tensile strength of the machine direction perforation line to the cross direction tensile strength of the product is from about 30% to about 60%.
2. The wiper product of claim 1 , wherein the at least one MD perforation line has a perforation tensile of at least about 750 g/3 inches.
3. The wiper product of claim 1 , wherein the wiper product further comprises at least one CD perforation line.
4. The wiper product of claim 3 , wherein the at least one CD perforation line has a percent bond area of at least about 15%.
5. The wiper product of claim 3 , wherein the perforation strength of the MD perforation line is greater than the perforation strength of the CD perforation line.
6. The wiper product of claim 3 , wherein the ratio of the perforation strength of the MD perforation line to the perforation strength of the CD perforation line is between about 0.9 and about 1.7.
7. The wiper product of claim 3 , wherein the MD perforation line has longer bonds in an area where the MD perforation line and CD perforation line intersects.
8. The wiper product of claim 1 , wherein the wiper has a SAT absorbent capacity is at least about 300 grams/sq. meter.
9. The wiper product of claim 1 , wherein the MD perforation line comprises a cut length of at least about 2.0 mm.
10. The wiper product of claim 1 , wherein the MD perforation line comprises a bond length of at least about 0.5 mm.
11. The wiper product of claim 1 , wherein the cuts make up at least about 50% of the length of the MD perforation line.
12. The wiper product of claim 1 , wherein the wiper is pre-moistened.
13. The wiper product of claim 12 , wherein the wiper is premoistened with at least one of a soap composition, a cleaning solution, a lotion, an anti-bacterial composition, or an anti-viral composition.
14. The wiper product of claim 1 , wherein the at least one MD perforation line has a percent bond area of at least about 15%.
15. The wiper product of claim 1 , wherein the ratio of cut lengths to bond lengths for the MD perforation line is less than about 7.
16. The wiper product of claim 1 , wherein the MD perforation line bisects the base sheet into two equally sized base sheets.
17. The wiper product of claim 1 , wherein the base sheet is airlaid, spunlaced, spunbonded or hydroentangled.
18. A partionable wiper product comprising:
a base sheet having a SAT absorbency of at least about 500 g/sq. meter and a basis weight of at least 25 g/sq. meter;
wherein the wiper product comprises at least one MD perforation line;
wherein the at least one MD perforation line has a percent bond area of at least about 15%, a cut length of at least about 2.0 mm, and a bond length of at least about 0.5 mm; and
wherein the ratio of the tensile strength of the machine direction perforation line to the cross direction tensile strength of the product is from about 30% to about 60%.
19. The wiper product of claim 18 , wherein the wiper is pre-moistened.
