Mechanical fastening system for an article
View Patent ↗A method of forming a post bonded loop laminate material includes providing a first layer of material comprising a nonwoven web of loop material having fibers and applying a force to the nonwoven web of loop material to generally orient the fibers in the direction of the applied force. The first layer of material is laminated to a second layer of material while applying the force to the nonwoven web of loop material to form a nonwoven loop laminate material. The first layer of material is bonded to the second layer of material after forming the nonwoven loop laminate material to form a post bonded loop laminate material.
1. A method of forming a post bonded loop laminate material suitable for use in a hook and loop fastening system for an article comprising:
providing a first layer of material comprising a nonwoven web of loop material having fibers defining loops;
applying a force to the nonwoven web of loop material to generally orient a greater number of the fibers in the direction of the applied force to increase the number of loops available in a direction perpendicular to the direction of the applied force;
laminating the first layer of material to a second layer of material while applying the force to the nonwoven web of loop material to form a nonwoven loop laminate material and to maintain the orientation of the fibers generally oriented in the direction of the applied force; and
bonding the first layer of material to the second layer of material after forming the nonwoven loop laminate material to form a post bonded loop laminate material.
2. The method of claim 1 wherein applying the force to the nonwoven web of loop material causes the nonwoven web of loop material to neck in a direction generally perpendicular to the direction in which the force is applied.
3. The method of claim 1 wherein applying the force to the nonwoven web of loop material causes the nonwoven web of loop material to gather.
4. The method of claim 1 wherein applying the force to the nonwoven web of loop material comprises applying a force to the nonwoven web of loop material only in the machine direction.
5. The method of claim 1 wherein applying the force to the nonwoven web of loop material comprises applying a force to the nonwoven web of loop material only in the cross-machine direction.
6. The method of claim 1 further comprising stabilizing the nonwoven web of loop material after the force has been applied thereto.
7. The method of claim 6 wherein stabilizing the nonwoven web of loop material comprises thermally treating the nonwoven web of loop material.
8. The method of claim 1 further comprising elongating the second layer of material prior to laminating the first layer of material to the second layer of material, the first layer of material being laminated to the second layer of material while the second layer of material is elongated.
9. The method of claim 8 wherein the second layer of material is elongated in the machine direction.
10. A method of forming a post bonded loop laminate material suitable for use in a hook and loop fastening system for an article comprising:
providing a first layer of material comprising a nonwoven web of loop material having fibers defining loops;
applying a force in a machine direction to the nonwoven web of loop material to generally orient the fibers in the machine direction thereby causing the nonwoven web of loop material to have more loops available in a cross-machine direction than in the machine direction;
laminating the first layer of material to a second layer of material while applying the force to the nonwoven web of loop material to form a nonwoven loop laminate material and to maintain the orientation of the fibers generally oriented in the machine direction; and
bonding the first layer of material to the second layer of material after forming the nonwoven loop laminate material to form a post bonded loop laminate material.
11. The method of claim 10 wherein applying the force to the nonwoven web of loop material causes the nonwoven web of loop material to neck in a direction generally perpendicular to the direction in which the force is applied.
12. The method of claim 10 further comprising stabilizing the nonwoven web of loop material after the force has been applied thereto.
13. The method of claim 12 wherein stabilizing the nonwoven web of loop material comprises thermally treating the nonwoven web of loop material.
14. The method of claim 10 further comprising elongating the second layer of material prior to laminating the first layer of material to the second layer of material, the first layer of material being laminated to the second layer of material while the second layer of material is elongated.
15. The method of claim 14 wherein the second layer of material is elongated in the machine direction.
