State of Stain Particle's ADhesion and Its Influence on Visual Consequence of Soil-Removal

오염입자의 부착상태가 시각적인 세정효과에 미치는 영향

Degree of separation and adhesion of dye and stain particles has been measured usually by the rate of reflection of light. However, it could be proved that the relation between the quantity of stain and the rate of reflection greatly varied with kinds of stain and states of adhesion. For this study, several pieces of cotton and polyester having different states of stain adhesion were prepared by staining them with two kinds of artificial stain different in color: Ferric Oxide and Ferric Oxynate. Every piece went through soilremoval test which employed two surfactants: Anionic LAS and Cationic M2-100. After the operation, relations between quantity of pre-soilremoval stain and rate of reflection were measured, as well as those between quantity of post-soilremoval stain and rate of reflection. Rate of reflection and quantity of stain were not proportional in measurement to the pieces stained with Ferric Oxide and Ferric Oxynate. The consequence was also the same with cotton and polyester. That held true of the fat-stained textile. With the same quantity of stain, rate of reflection varied according to the magnitude of stain particles, and the state of adhesion influenced the magnitude of stain particles a great deal.
