Micro-Encapsulation Coating Systems
topic
Microencapsulated functional agent coating applies suspensions of polymer-shelled microcapsules containing fragrance, phase change material, moisturiser, or biocide at 5 to 30 grams per square metre by gravure, knife, or screen coating onto textile substrates, with microcapsule rupture during wear or use releasing the encapsulated active agent, with capsule integrity through coating, drying, and laundering being the critical quality requirement for durable functional performance.
Role
Enables durable functional finish application for extended-release fragrance, thermoregulation, and cosmetic textile applications through microencapsulation that protects active agents from environmental degradation and laundering loss, providing substantivity that unencapsulated active agents cannot achieve, with microcapsule coating system design governing the balance between adequate capsule adhesion to the textile surface and accessibility for rupture and release during use.
