Method for thermal fixing of fabric e.g. press felt, in paper making machine, involves exposing region of fabric along entire width and certain length of fabric to saturated steam at specific pressure and temperature ranges

摘要

The method involves guiding a fabric e.g. press felt (1), in a longitudinal direction over two spaced apart supporting members (2a, 2b), and applying longitudinal stretching force to the fabric. A region of the fabric along the entire width and a certain length of the fabric is exposed to saturated steam at a pressure of 101.4 to 120.0 kilo Pascals (kPa) and at a temperature of 100 to 130 degrees Celsius. Another region of the fabric downstream of the former region is exposed to superheated steam at a pressure of 101.4 to 120.0 kPa and at a temperature of 160 to 200 degrees Celsius. An independent claim is also included for a device for thermal fixing of a woven fabric.
