Abstract
An industrial process fabric is embossed in a device, such as a continuously operating two-roll calender having a preselected embossing pattern. The roll(s) of the calender may alternatively themselves be engraved or etched to provide the embossing. Embossing takes place with controlled temperature, pressure, speed and gap (between the rolls) settings. The fabric may be a forming, press, dryer or TAD fabric used in paper and pulp production, pulp forming fabric or an engineered fabric used to produce nonwoven textile products by meltblowing, spunbonding, hydroentangling or air laid needle punching.
