This study aimed to investigate the production of multi-layered capsules containing two
different active substances and the possibilities of using the obtained capsules in the textile sector,
thereby balancing the body temperature with the phase changing material to be used, and to provide a
second feature in addition to balancing the body temperature with the other active substance. In this
study, a phase change material as the first core material was microencapsulated with melamine
formaldehyde prepolymer, then the resulting microcapsules were subjected to a second
microencapsulation process to form the mandarin oil as a second core material and ethyl cellulose as
a second capsule wall. Single layer microcapsules were produced according to the in-situ
polymerization method, and multilayer microcapsules were produced according to the coaservation
method. Particle size and distribution analysis, DSC, FT-IR and SEM were performed to single layer
and multilayer microcapsules. Also, imaging with a thermal camera were applied to detect the capsule
effectiveness of microencapsulated fabrics.
