Mechanical fastening system for an absorbent article
View Patent ↗An absorbent article such as infant training pants is provided with a mechanical hook-and-loop type fastening system in which at least the loop material is made of a laminate with a facing having a bond density of greater than 225 points per square inch.
1. A mechanical fastening system for an article, said mechanical fastening system comprising:
a stretchable loop fastener component mountable on the article and comprising a stretch bonded laminate, said stretch bonded laminate comprising an elastomeric substrate and a high bond point nonwoven loop material having greater than 225 bond points per square inch; and
a hook fastener component mountable on the article and adapted for releasable engagement with the loop fastener component;
wherein the stretchable loop fastener component is stretchable relative to the hook fastener component when the fastener components are engaged.
2. The mechanical fastening system of claim 1 wherein the stretchable loop fastener component can be elastically stretched at least 100 percent in at least one direction.
3. The mechanical fastening system of claim 1 wherein the high bond point nonwoven loop material has a bond area of greater than 10 percent.
4. The mechanical fastening system of claim 3 wherein the high bond point nonwoven loop material has a bond area of greater than 20 percent.
5. The mechanical fastening system of claim 4 wherein the high bond point nonwoven loop material has a bond area of greater than 30 percent.
6. The mechanical fastening system of claim 1 wherein the high bond point nonwoven loop material has at least 250 bond points per square inch.
7. The mechanical fastening system of claim 6 wherein the high bond point nonwoven loop material has a bond area of greater than 20 percent.
8. The mechanical fastening system of claim 7 wherein the high bond point nonwoven loop material has a bond area of greater than 30 percent.
9. The mechanical fastening system of claim 1 wherein the high bond point nonwoven loop material has at least 275 bond points per square inch.
10. The mechanical fastening system of claim 9 wherein the high bond point nonwoven loop material has a bond area of greater than 20 percent.
11. The mechanical fastening system of claim 10 wherein the high bond point nonwoven loop material has a bond area of greater than 30 percent.
12. The mechanical fastening system of claim 1 wherein the high bond point nonwoven loop material is mechanically prestrained.
13. The mechanical fastening system of claim 12 wherein the high bond point nonwoven loop material is neck-stretched.
14. The mechanical fastening system of claim 1 wherein the high bond point nonwoven loop material has at least 300 bond points per square inch and a bond area of greater than 10 percent.
15. The mechanical fastening system of claim 14 wherein the high bond point nonwoven loop material has a bond area of greater than 20 percent.
16. The mechanical fastening system of claim 15 wherein the high bond point nonwoven loop material has a bond area of greater than 30 percent.
17. The mechanical fastening system of claim 1 in combination with a disposable absorbent article for personal wear, said disposable article comprising a body having first and second end regions and comprising an inner layer for contact with the wearer's skin, at least a portion of the inner layer being liquid permeable, an outer layer in opposed relation with the inner layer, and an absorbent layer disposed between the inner layer and the outer layer, the loop fastener component being disposed on the absorbent article in the first end region and the hook fastener component; being disposed on the absorbent article in the second end region.
