Tests are given for hot pressing when the textile is dry, when it is wet, and when it is damp. The end-use of the textile usually determines which test should be made. A dry specimen (dry pressing) or a dry specimen covered with a wet cotton adjacent fabric (damp pressing) or a wet specimen covered with a wet cotton adjacent fabric (wet pressing) are pressed with a heating device at a specified temperature and pressure for a specified time.
