| abstract |
The present invention concerns double-walled microcapsules with an outer thermoplastic wall and an application process thereof on substrates, namely textile substrate. The microcapsules are applied to fibres so as to produce a slow release of products such as fragrances, antimicrobial, insecticides, antioxidants, vitamins or they can be used as materials such as thermochromic pigments, that change colour when heated, or “phase change materials” (PCM), that convey thermal insulation/control. |
