standard by Technical Association of the Pulp and Paper Industry, 04/27/2015
Full Description
This Technical Information Paper provides a means of measuring several fabric characteristics of new press fabrics. For on-machine monitoring of the press fabric, refer to TAPPI TIP 0404-19 "Press Section Monitoring."
The characteristic properties covered in this TIP are: a) the basis weight or unit area weight, b) the air permeability, c) the void volume and d) the pressure uniformity of a press fabric.The supplier typically performas these measures.
This revision combines information from earlier version of TIP 0404-20 from material from withdrawn TIPs 0404-32 and 0404-34.
