AATCC 99 Dimensional Changes of Woven or Knitted Wool Textiles - Relaxation, Strengthening and Felting

EUROLAB laboratory provides testing and compliance services within the scope of AATCC 99 standard. The AATCC 99 standard is an accelerated test for determining the relaxation, consolidation and felting shrinkage of woven and knitted textiles containing 50% or more wool.

The overall size change in a fabric during home washing is an important performance factor for the final consumer of a garment. However, further analysis of dimensional change components is invaluable to a fabric manufacturer, as it allows the fabric manufacturer to make appropriate changes in the design and treatment of fabrics to reduce their tendency to change dimensionally when washed.

Generally, three types of dimensional changes occur under different environmental conditions. These are relaxation, hygral and thermal dimensional changes. Dimensional stability tests measure moisture changes and possible dimensional changes in fabric and clothing, among which relaxation shrinkage and hygral expansion are very important. Relaxation shrinkage and hygral expansion together; It can cause problems in sewing appearance, size numbering, shrinkage, pattern placement, and the appearance of the finished garment and during wearing.

Our organization, EUROLAB, provides dimensional changes - loosening, consolidation and felting services of woven or knitted wool textiles, within the framework of national and international standards, with its trained and expert staff and advanced technological equipment, among numerous test, measurement, analysis and evaluation studies. Contact EUROLAB to get testing service under the AATCC 99 standard.
