Net hook fasteners
The present invention concerns a polymeric film hook netting comprising a continuous film backing having a net section formed of plurality of a first set of thermoplastic strands extending in a first direction and a second set of integral strands extending in a second direction at least one of which strands has upstanding hook elements and a second integral non-net film section.
1. A polymeric film hook netting comprising a continuous polymeric film backing having a net section and a second integral non-net film section, where the net section is formed of a first set of a plurality of thermoplastic strands extending in a first direction and a second set of a plurality of integral strands extending in a second direction at least one of which sets of strands has upstanding hook elements.
2. The polymeric film hook netting of claim 1 wherein the percent open area of the net section is at least 50 percent.
3. The polymeric film hook netting of claim 1 wherein the percent open area of the net section is at least 60 percent.
4. The polymeric film hook netting of claim 1 wherein the first set of strands extend in the transverse direction and are nonplanar and the second set of strands extend in the longitudinal direction and are nonrectilinear.
5. The polymeric film hook netting of claim 1 wherein at least one of said sets of strands are oriented strands.
6. The polymeric film hook netting of claim 5 wherein the other set of strands are not oriented and have a substantially rectilinear cross-section.
7. The polymeric film hook netting of claim 1 wherein at least one of said sets of strands are linear.
8. The polymeric film hook netting of claim 1 wherein both sets of strands are nonlinear.
9. The polymeric film hook netting of claim 1 wherein said hook elements extend in the direction of one of the sets of strands.
10. The polymeric film hook netting of claim 1 wherein said hook elements extend in two or more directions.
11. A fastening tab for an article comprising a polymeric film hook netting having a continuous film backing having a net section formed of plurality of a first set of thermoplastic strands extending in a first direction and a second set of integral strands extending in a second direction at least one of which strands has upstanding hook elements and a second integral non net film section for attachment to the article.
12. The fastening tab of claim 11 wherein the non net section is coated with a pressure sensitive adhesive.
13. The fastening tab of claim 11 wherein the percent open area of the net section is at least 50 percent.
14. The fastening tab of claim 11 wherein the percent open area of the netting is at least 60 percent.
15. The fastening tab of claim 11 wherein the first set of strands extend in the transverse direction and are nonplanar and the second set of strands extend in the longitudinal direction and are nonrectilinear.
16. The fastening tab of claim 11 wherein at least one of said sets of strands are oriented strands.
17. The fastening tab of claim 16 wherein the other set of strands are not oriented and have a substantially rectilinear cross-section.
18. The polymeric film hook netting of claim 17 wherein said hook elements extend in the direction of one of the sets of strands.
