%X The degradation or hydrolysis of PET by sodium hydroxide was studied by infra red, dual ware length scanning thin layer chromatography, gel permeation chromatog-raphy and X-ray diffraction. It was observed that the concentration of sodium hydroxide may be greatly reduced by the addition of a certain amount of cationic surface active agent, quarternary ammonium salt.The alkali attacks and dissolves the PET from the surface of the fiber. At definife concentrotion of sodium hydroxide and dodeeyl dimethyl benzyl ammonium bromide the molecular weight or molecular weight distribution of the undissolved PET remains near-ly unchanged.
