Abstract
Process for making a variable stretch composite comprising the steps of providing a first extensible fibrous substrate, printing a first elastomeric composition to a first elasticized region of the substrate, printing a second elastomeric composition to a second elasticized region of the substrate, and incrementally stretching at least a portion of the composite perform to form a variable stretch composite.
Claims28
A process for making a variable stretch composite comprising the steps of:
- (a) providing a first extensible fibrous substrate;
- (b) printing a first elastomeric composition in a fluid state either directly or indirectly to a first elasticized region of the substrate to form one or more first elastomeric members;
- (c) printing a second elastomeric composition in a fluid state either directly or indirectly to a second elasticized region of the substrate, to form one or more second elastomeric members, thereby forming a composite preform;
- the first and the second elastomeric members are different in a property selected from the group consisting of elasticity, melt viscosity, composition, shape, pattern, add-on level, and combinations thereof;
- and
- (d) incrementally stretching at least a portion of the composite preform within the first or the second elasticized region to permanently elongate the substrate, thereby forming the variable stretch composite;
- wherein the substrate comprises a single absorbent article component;
- and
- wherein the variable stretch composite has a directional elasticity in at least one direction from about 5 N/m to about 400 N/m, when measured as load at 75% strain.
