AATCC Test Method 133-2013
Colorfastness to Heat:  Hot Pressing

 

Developed in 1969 by AATCC Committee RR54

1.  Purpose and Scope

1.1  This test method is intended for determining the resistance of the color of textiles of all kinds and in all forms to color change, and color transfer when subjected to hot pressing.  Tests are given for hot pressing when fabric is dry, damp and wet.   The textile end use usually determines which tests should be made.

2.  Principle

2.1  Dry Pressing.  The dry specimen is pressed with a heating device of a specified temperature, time and weight.
2.2  Damp Pressing.  The dry specimen is covered with a wet, undyed cotton cloth and pressed with a heating device of a specified temperature, time and weight.
2.3  Wet Pressing.  The wet specimen is covered with a wet, undyed cotton cloth and pressed with a heating device of specified temperature and weight.
