The Effects of Water-and Oil-Repellent Finishes on the Deposition and Removal of Oily Soils from Polyester Fabrics
이정숙
ABSTRACT
The effects of water-and oil-repellent finishes on the deposition and removal of oily soils from polyseter fabrics were investigated in this study. The polyester fabrics treated with three kinds of fluoropolymers(TG-410H, TG-990) were soiled with mixed oily soils and washed by using Terg-O-Tometer at various conditions. It was found that TG-410H and TG-527 treated polyester fabrics reduced significantly the deposition of oily soils than untreated and TG-990 treated polyester fabrics. The removal of oily soils from polyester fabrics was increased in porportion to increasing of surfactant concentration up to a certain point(0.2% owb) but it levelled off above the point. The removal effect was high in the order of TG-990 treated polyester fabrics > untreated polyester fabrics > TG-527 treated polyester fabrics > TBG-410H treasted polyester fabrics. Especially the removal of oily soils from polyester fabrics was more effectively removed in triton X-100 solution. In general the removal of oily soils from polyester fabrics treated with fluoropolymers was increased up to a miximum near 60oC and than decreased above 60oC. And efficient removal could be achieved within relatively short time (30min) The removal of oily soils from polyester fabrics was increased in proportion to increasing of pH range up to a certain point(9.5 or 11.0) but it began to decrease above the point. Furthermore the removal of oily soils was increased with th increase of mechanical agitation, but it began to decrease above 160 rpm.
