1. PURPOSE AND SCOPE 1.1 This method determines, in a single treatment, the dimensional changes
(shrinkage or stretch) that may occur in a fabric as a result of
relaxation of strain, during any of the following treatments: commercial preshrinking of wool or part-wool fabrics (sponging) dry cleaning in solvent systems containing dissolved water¹ pressing involving moisture wet cleaning involving wetting of the fabric with an aqueous detergent
solution followed by gentle hand brushing to remove soil and gentle
hand rinsing. 1.2 The testing and evaluation of a product against this method may
require the use of materials and/or equipment that could be hazardous.
This document does not purport to address all the safety aspects
associated with its use. Anyone using this method has the
responsibility to consult the appropriate authorities and to establish
appropriate health and safety practices in conjunction with any
applicable regulatory requirements prior to its use. 1 Experience has shown that this method for dimensional change in wetting gives
good correlation with the dimensional change due to relaxation of fabric
strains in repeated dry cleanings.
