Abstract
Sorption of amphiphilic compounds in polyester fiber above 200°C increases hydrophilicity of the fiber and facilitates oily soil removal. Hydrophilicity of the treated fabric depends upon the structure of the amphiphile. Sorption of carboxylic or sulfonic acid salts is related to their compatibility with the fiber or a fiber-like model solvent and decreases with the increasing size of their alkali metal ion: Li+ > Na+ > K+. The parent carboxylic acids to not increase hydrophilicity of the fiber. Quaternary ammonium halides with a long hydrocarbon chain increase hydrophilicity, but primary, secondary, or tertiary amine hydrochlorides are ineffective. The efficacy of nonionic surfactants in increasing hydrophilicity depends upon their hydrophilic-lipophilic balance (HLB) values; surfactants with HLB values of 13 to 16 are most effective.
