This invention refers to agglomerates of microcapsules obtained from microcapsules of phase change materials (PCM) and their application in fibrous or porous polymeric materials, par¬ ticularly articles with the capacity for temperature regulation. PCM Microcapsules are connected to each other by chemical bonds that form agglomerates, which link directly to the fibres without the need for the addition of a binder, when applied to the materials herein referred to. The application in the fibrous or porous polymeric materials can be done by means of melting the outer thermoplastic wall (in the case of self-adhesive microcapsules) or reacting the micro¬ capsules and functional groups (in the case of individual insertion or agglomerates). The articles that contain these agglomerates have better mechanical resistance to washing since this procedure allows the intake of a suitable microcapsule quantity, which form a larger group than the spaces between the fibres or the pores. On the other hand, the microcapsules linked to fibres or other materials will be better protected because they comprise cohesive assemblies that will better resist against friction forces. |
