Textile Test Methods - Colourfastness to Dry Cleaning Solvent

This method assesses the fastness of the colour of textile fabrics and yarns to dry cleaning solvent. The results  of  this  test  have  been  found  to  correlate satisfactorily with those obtained in  commercial dry cleaning,  although the  test  does  not  make  use  of moisture or  dry-cleaning soap as generally used in commercial dry cleaning.  This method makes use of tetrachloroethylene since experience has shown that coloured textiles that will withstand cleaning in tetrachloroethylene will also withstand cleaning in other dry cleaning solvents (e.g., Stoddard solvent).  The reverse, however, is not necessarily true.  This method does not provide for assessment of staining since, despite the presence of colour in the cleaning solvent, staining of white or light-coloured textiles occurs very seldom in dry cleaning.
