Improvement of Microcapsule Adhesion to Fabrics

Abstract

The presence of microcapsules has increased in the textile field. They have been applied as a possible means of introducing new products to textiles, such as fragrances, antibiotics, skin hydrants, etc. This work studied the influence of resin on the adhesion of microcapsules to cotton fabrics. To paste microcapsules to fabrics, they should be in contact with a bath which contains microcapsules, resin and water. Different concentrations of resin were applied to a fragrance microcapsule bath by impregnation. This research focuses on determining the influence of resin quantity on the microcapsule resistance to washing out of the fabrics during washing treatments. Two experimental techniques, scanning electron microscopy and counter apparatus, were used to determinate this influence. We conclude that with a higher quantity of resin, more microcapsules remain on the fabric surface. It was shown that longer microcapsules are washed out of the fabric faster than smaller microcapsules.
