Functionalized particles comprising a shell and a core and a payload that is embedded or entrapped, wherein the shell matrix is obtained by interfacial polymerisation of vinyltriethoxy silane and at least one other ethylenically unsaturated monomer copolymerizable with vinyltriethoxy silane, said functionalized particles being capable to chemically bind to a substrate, are suitable as controlled release systems for textile applications to impart durable softness and excellent water retention even after multiple laundries. Des particules fonctionnalisées comprennent une écorce et un cœur et une charge utile qui est incorporée ou piégée, la matrice d'écorce étant obtenue par polymérisation interfaciale de vinyltriéthoxy silane et d'au moins un autre monomère éthyléniquement insaturé copolymérisable avec le vinyltriéthoxy silane, lesdites particules fonctionnalisées étant capables de se lier chimiquement à un substrat, sont appropriées en tant que systèmes de libération contrôlée pour des applications textiles pour conférer une souplesse durable et une excellente rétention d'eau même après de multiples lavages.
