PHYSICAL CHARACTERIZATION OF PRESS FABRICS: BASIS WEIGHT, AIR PERMEABILITY, VOID VOLUME UNDER LOADING AND PRESSURE UNIFORMITY

• 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
  • The basis weight or unit area weight.
  • The air permeability.
  • The void volume.
  • The pressure uniformity of a press fabric.
• The purpose of this method is to note the conditions under which a press fabric is measured for size and basis weight. This procedure is intended for use either in the mill or in a laboratory.

It Provides information on:

• Scope.
• Test specimens.
• Procedure.
• Report.
• Keywords.

Who will benefit:

• Researchers.
• Laboratory Personal.
