Abstract
In the previous report, the antistatic effect of the surfactants on propylene fibres relating to their stability for temperature, humidity and for heat-setting has been studied.
In this paper, differences in degree of antistatic effect of them on the above mentioned fibres by prolonged storage were investigated.
Alkyl-phosphates, quarternary ammonium type cationics and betain type amphoterics gave good results even after 90 day storage, and in the case of other surfactants, the diminutions of the antistatic effect by prolonged storage were comparatively low.
