Purpose of Test
This test evaluates the pH levels of wet-processed textiles. In this test, the chemicals affecting pH are removed from the textile and collected as water extract to measure the pH level.
pH – Measurement of how acidic or basic a liquid is.
Wet Processing – The manufacturing stage of textile where it gets treated with colorants or chemicals.
pH meter – A device used for evaluating the acidity or alkalinity of a liquid solution.
Materials Used for Test
- Test specimen
- Distilled water or deionized water
- pH meter
The test specimen is boiled in deionized or distilled water. The extracted water is cooled to room temperature and evaluated for ph level.
Test Procedure (Summary)
Part 1: Boiling of test specimen: The test specimen is boiled using deionized or distilled water.
Part 2: Water extraction: The water is extracted from the test specimen and let cool until it hits room temperature. The pH level is evaluated.
