Abstract
A zoned hot air knife assembly and process include a plurality of discrete, spaced apart air knives is useful for the inter-filament bonding of nonwoven webs, for the thermal bonding of laminates including nonwoven webs, and other applications. The zoned hot air knife assembly and process facilitate the manufacture of low bond area, low density nonwoven webs and laminates having high structural integrity. The zoned hot air knife also reduces the amount of heated air and, thus, energy required for the production of thermally bonded nonwoven webs and laminates.
Claims (29)
1. A method of increasing the integrity of a nonwoven web or laminate including the web, comprising the steps of:
transporting the web or laminate in a machine direction along a conveyor; and applying heated air jets to the nonwoven web at a plurality of spaced apart locations, the heated air jets being spaced apart in a direction transverse to the machine direction.
transporting the web or laminate in a machine direction along a conveyor; and applying heated air jets to the nonwoven web at a plurality of spaced apart locations, the heated air jets being spaced apart in a direction transverse to the machine direction.
2. The method of Claim 1, wherein at least three of the heated air jets are applied to the nonwoven web at spaced apart locations.
3. The method of Claim 1, wherein at least five of the heated air jets are applied to the nonwoven web at spaced apart locations.
4. The method of Claim 1, wherein at least six of the heated air jets are applied to the nonwoven web at spaced apart locations.

23. The method of Claim 13, wherein the average bonded density is less than about 0.045 grams/cc, measured under a load of 0.05 psi.
24. A method of bonding a nonwoven web or laminate including the web, comprising the steps of:
applying heated air jets to the nonwoven web at a plurality of spaced apart locations to cause thermal bonding of some of the filaments in the web; and subjecting the web or laminate including the web to a second bonding process.
applying heated air jets to the nonwoven web at a plurality of spaced apart locations to cause thermal bonding of some of the filaments in the web; and subjecting the web or laminate including the web to a second bonding process.
25. The method of Claim 24, wherein the second bonding process comprises through-air bonding of the nonwoven web.
26. The method of Claim 24, wherein the second bonding process comprises thermal point bonding of the nonwoven web.
