Claims10
A process for making an elastic embossed laminate comprising:
- thermally point bonding a facing layer to an elastic layer with a bonding roll to imparts a first pattern while the elastic layer is in the stretched state to at least partially form an elastic laminate having a first peel strength;
- embossing the elastic laminate with embossing rolls to impart a second pattern while the elastic laminate is in the relaxed state to at least partially form embossments on the embossed elastic laminate, wherein the embossed elastic laminate has a second peel strength greater than the first peel strength;
- heating the bonding rolls to a temperature of at least 30 degrees Fahrenheit higher than the temperature of the embossing rolls, wherein the embossed elastic laminate has a greater load capacity at 50% elongation than the elastic laminate.
