A laminate material formed of an elastomeric polymer sheet and a nonwoven fabric sheet. The sheets are passed through a niproll assembly during lamination, one of the niprolls having a series of embossing points protruding therefrom, and the other niproll being substantially flat. The embossing points press selective areas of the preferably molten polymer sheet into the fabric sheet, encapsulating the fabric fibers and bonding thereto. The resulting material has points of bonding where penetration has occurred and areas of nonpenetration, providing adherence of the two sheets while permitting independent movement of the fibers and elastic properties. Preferably, a release agent is added to the elastomeric polymer to reduce the possibility of the elastomer layer sticking to the nonwoven layer when the laminate is wound onto a supply roll.
An elastic laminated fabric, comprising a first sheet of an elastomeric polymer and a second sheet of fabric, whereby portions of the polymer of said first sheet are selectively attached to said second sheet by point bonding so that said polymer encapsulates fibers of said second sheet at the points of bonding and whereby said laminated fabric has an elasticity measurement of from about 0.15 to about 0.22 retraction force/extension force ratio and an internal cohesion of from about 6.3 to about 6.7 kg.
An elastic laminated fabric formed by the process comprising:
An elastic laminated fabric having a first sheet of an elastomeric polymer containing a release agent and a second sheet of a nonwoven material, whereby portions of said first sheet are pushed into said second sheet by point embossing during lamination, such that the resulting laminate has points of bonded areas and the remaining areas are not bonded to each other and whereby said laminated fabric has an elasticity measurement of from about 0.15 to about 0.22 retraction force/extension force ratio and an internal cohesion of from about 6.3 to about 6.7 kg.
A method of forming an elastic laminated fabric, comprising:
