AATCC Test Method 99-2004
Dimensional Changes of Woven or Knitted Wool Textiles:
Relaxation, Consolidation and Felting

Developed in 1960 by AATCC Committee RA42

1.  Purpose and Scope

1.1  This method is an accelerated test for determination of relaxation, consolidation and felting shrinkage of woven and knitted textiles containing 50% or more wool.
1.2  The overall dimensional change in a fabric during home laundering is a significant performance factor to the ultimate consumer of the garment.  However, further analysis of the components of dimensional change is invaluable to a fabric manufacturer, since it allows the fabric manufacturer to make appropriate changes in design and processing of fabrics to reduce their tendency to change dimensionally when washed.
