Reactive Microcapsule Technology
Patented (WO/2006/117702)
Controlled affinity and covalent reaction with fibres through available
functional groups (shells to fibres).
Well-established chemical bond that guarantees optimum adhesion
and thus promoting higher resistance towards washing and abrasion.
Efficient linkage compared with traditional binding routes.
Enhanced microcapsules’ release mechanism from treated substrates.
Work on the adhesion and wash durability.

PU Microcapsules – Self Healing
Self-Healing Concept
‘Self-healing can be defined as the ability of a material to
heal (recover/repair)damages automatically and
autonomously, that is, without any external intervention.’*
Common goal: mimicking biological systems
