Description

At the standpoint of the preservation of environment, possibility of substitute solvent in dry cleaning was investigated by using 3 kinds of propylene glycol ether (propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monopropyl ether) and ethanol.The removal of pigment soil with various water-propylene glycol ether mixture solvent was investigated using 7 kinds of soiled cotton cloths. The removal experiment was carried out using an incubator, and the removal efficiency was determined by K/S value to reflectance of soiled cotton cloths before and after the detergency. The maximum removal degree of water-soluble pigments was attaind at 40〜60vo1% solvent and that of oily pigments was attaind at 50〜100 vo1% solvent, in the case of 24h at 20C.In 4 kinds of solvent, the degree of removal decreased in the order: propylene glycol monopropyl ether > propylene glycol monoethyl ether>propylene glycol monomethyl ether > ethanol. It was suggested that the detergent efficiency was affected by the surface tension and solubility of oily pigment.
