Textile substrate containing thermal regulation composition, for use e.g. in clothing with temperature regulating effect, includes islets of material for promoting heat and/or moisture transfer

摘要

A fiber-containing textile substrate (A), incorporating a thermal regulation composition (I), also has 'islets', associated with the fibers and surrounded by (I), of material (II) for promoting the transfer of heat and/or moisture into (I). An independent claim is included for the production of (A), incorporating (I) and (II), where (I) is in the form of microcapsules (MC's) containing phase-change material (Ia), by: (1) preparing a formulation containing the MC's, comprising (Ia) in a shell of material (III) with groups reacting under ionizing radiation (IZR), and a crosslinker (IV) with two types of groups reacting under IZR; (2) applying (II) to at least one zone on the surface of (A) in the form of islets; (3) impregnating (A) with the MC formulation; and (4) irradiating with IZR to crosslink the MC's on (A) via the reactive groups.
