the topsheet thereby avoiding a feeling of wetness for a wearer application_number US 87644001 A description both direct melt and reheat processes are in this invention considered to be equivalent methods under the term vacuum formed films vff since both melt form and recrystallize in a three dimensional shape each of the processes may be used to form films wherein the loft of the cells are robust polymer webs have a property known as u201c memory u201d wherein a polymer web will tend to revert to its original shape therefore if a polymer web is formed as a flat web and then forced into a three dimensional shape without undergoing melting and recrystallizing the polymer web will try to revert again to its original flat shape when any stresses are subsequently applied robustness in the third dimension is critical for obtaining and then maintaining u201c loft u201d which prevents rewet two important variables are commonly discussed when describing a vff loft and ao u201c loft u201d is defined as the top to bottom thickness of the vacuum formed film which is typically the required spacial distance between a fluid containing absorbent core and the skin of the user or the thickness of the vacuum formed film loft is typically measured by the same means used to measure u201c embossed thickness u201d in the polymer film industry embossment is merely imparting a third dimension to the film typically ne with defined pattern and shape commonly used devices for this measurement are called u201c low load.
