The ISO 9073-2 standard, developed by the International Standards Organization (ISO), describes a test method for determining the thickness of normal and bulky non-woven textile products under a certain pressure. Although non-woven fabrics are classified within the textile sector, it is accepted that non-woven fabrics have technologically common features not only with textile products, but also with paper and plastic products. There is an international standard ISO 5084 for the purpose of determining the thickness. This standard describes a test method for determining the thickness of textiles and textile products (excluding textile floor coverings, nonwovens and geotextiles). However, alternative requirements to those listed in ISO 5084 are described in ISO 9073-2 to meet the specific needs of nonwovens. These requirements are:
For the purposes of ISO 9073-2 standard, bulk nonwoven refers to non-woven textiles that can be compressed by 0,1 percent or more when the applied pressure changes from 0,5 kPa to 20 kPa, and thickness refers to the distance between the face and back of the nonwoven fabric. is the distance between a reference plate on which it rests and a parallel presser foot that applies pressure to the nonwoven.
The ISO 9073-2 standard includes these three test methods:
Essentially, the ISO 9073 standard consists of the following parts
