ABSTRACT

In this study, dye encapsulated microcapsules were produced by polyurethane prepolymer synthesis method using hexamethylene diisocyanate, ethylene glycol and methyl ethyl ketone. The study showed that the average size of microcapsules were 4.697㎛ in normal distribution. These microcapsules were induced red color by thermochromic fluoran red dye with showing color change as temperature. After the textile finishing of microcapsules, durability of microcapsules were checked as crocking times and lightfastness. The microcapsules were pressed at protrusion of textile weave in 10 crocking times which meant that the microcapsules not fallen off. Lightfastness was acceptable giving rating 4. It means that the polyurethane microcapsules not affect to light durability.
