Abstract
This invention claims disposable garments comprising a stretchy laminate and methods of making the same.
Claims20
A disposable garment comprising first and second extensible nonwoven substrates and at least one elastic hot melt adhesive composition disposed between and bonding the first and second substrates, creating a stretchy bonded region;
- the elastic hot melt adhesive composition having a viscosity of less than about 200,000 cps at application temperature of around 177° C. and a set after 50% hysteresis of no greater than about 20%;
- and
- said disposable garment comprising:
- a front panel having a front waist edge substantially perpendicular to a pair of opposing first and second front longitudinal edges comprised of first and second hip edges which each end where a pair of first and second front leg edges begins;
- and
- a back panel having a back waist edge substantially perpendicular to a pair of opposing first and second front longitudinal edges comprised of first and second back hip edges which each end where a pair of first and second back leg edges begins;
- wherein when the first front hip edge is connected to the first back hip edge and the second front hip edge is connected to the second back hip edge, the front waist edge and the back waist edge form a torso opening, and the first front leg edge and first back leg edge form a first leg opening and the second front leg edge and the second back leg edge form a second leg opening;
- wherein the disposable garment is free of added elastic strand components.

A method of manufacturing a stretchy laminate comprising the steps of:
- providing a first and second extensible nonwoven substrates in a state such that it is not substantially extended beyond its original state in any direction during formation of the laminate;
- providing an elastic hot melt adhesive comprising a viscosity of less than about 200,000 cps at application temperature and a set after 50% hysteresis of no greater than about 20%;
- advancing each first and second extensible nonwoven substrate in a machine direction;
- applying the elastic hot melt adhesive in hot molten form to the first extensible nonwoven substrate;
- contacting the second extensible nonwoven substrate to the hot molten elastic hot melt adhesive coated first extensible nonwoven substrate to form a layered configuration;
- cooling the layered configuration to create a stretchy laminate bonded with the hot melt adhesive.
