Abstract: Abstract In this paper, the differences among different pH testing standards of textiles were analyzed, the influences of different pH testing standards on pH determination results and the correlation between pH determination results were tested and researched. It is showed that pH testing method of JIS and AATCC pH testing standards are convenient, but pH testing method of GB and ISO pH testing standards are fussy. The pH testing standards are arranged in increasing order of pH determination results, which is GB(ISO) and JIS and AATCC. The relations between pH determination results of JIS and AATCC pH testing standards are significant linear correlativity. The relations between pH determination results of GB(ISO) and JIS pH testing standards and between GB(ISO) and AATCC pH testing standards are better linear correlativity. The research results can supply a certain reference to the better application of pH testing standards to textiles industry and testing organization.
