摘要
Polycarboxylic acids have been widely researched as non-formaldehyde DP finishes since late 1980s. However, there has no satisfied wet chemical method for quantifi-cation the carboxylic groups or the esterlinkages on fab-ric, which is important in investigation some basic as-pects of the esterification between polycarboxylic acids and cellulose. In this paper, the wet chemical analysis method, Ca(AC)2 back - titration, had been established to determinate the COOH on fabric. The reliability of this method had also been proved.
