Functionalization of a textile substrate (A) with an active composition (I) involves: (i) preparing a formulation containing microcapsules (MC's), comprising (I) in a shell of material (II) with groups reacting under ionizing radiation (IZR), and a crosslinker (III) with two types of groups reacting under IZR; (ii) impregnating (A) with the formulation; and (iii) irradiating with IZR to crosslink the MC's on (A) via the reactive groups. Independent claims are included for: (1) the textile substrates (A) functionalized by the process, in which (A) incorporate the (I)-containing MC's in an amount of more than 10 g/m 2> and the shells of the MC's are crosslinked with the fibers of (A); and (2) textile articles formed from the functionalized substrate (A), having an inner textile layer on one side of (A) and an outer textile layer, designed to trap a volume of air, on the other side of (A).
