Abstract:
1. A one-step, one-location method of making a necked-bonded laminate, comprising: bonding a first plurality of filaments in a first bonding device operating at a first speed to form a first nonwoven web; necking the first nonwoven web; and feeding the first nonwoven web into a laminator operating at a second faster speed in a tensioned, necked condition, such that the first nonwoven web is conveyed from the first bonding device to the laminator within 24 seconds; and laminating an elastomeric film to the necked first nonwoven web in the laminator; wherein a difference between the first speed and the second speed necks the first nonwoven web before the first nonwoven web reaches 75% of a final crystallization and the neck-bonded laminate can be stretched by about 300% or more.
