Application of Contact Angle Measurement to the Manufacture of Textiles Containing Microcapsules

The efficiency of a binder to link microcapsules on a textile surface depends on the compatibility of the different interfaces of the products involved in the coating process. The choice of a binder adapted to the microcapsules was determined in this study by the comparison of the surface energy components induced by the contact angle measurement method and washing tests. It was found that a polyurethane-based binder was the most suitable to link melamine formaldehyde microcapsules. Furthermore, the adhesion of microcapsules was closely dependent on the chemical nature and structure of the textile support.
