AATCC 209 | pH and Total Alkali in Wet Processed Textiles: Combined |
1.1 This test method is used to determine the pH and total alkali content of wet processed textiles, pH and total alkali can be used to determine washing and/or neutralizing efficiency after certan wet processing steps, particularly bleaching, and can be used as a measure of the suitability of prepared fabric for subsequent dyeing and finishing operations. 1.2 To make a quantitative determination, the chemicals which influence pH must be removed from the textile specimen, collected as a water extract and then accurately measured by a pH meter.
