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 water (Note 1) 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. Note 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.
