Abstract
The present invention relates to a method of grafting, by covalent bonding, hollow or solid composite capsules onto any type of natural, artificial or synthetic, organic or inorganic, support, the capsules being chemically, physically or physico-chemically modified, so as possibly to improve their affinity with the support and to functionalize them, and then grafted, after the capsules and/or the support have been activated. The invention also relates to the capsules thus modified, to the supports grafted by the capsules, especially fibres and textiles, and also to the use of these grafted supports, especially fibres and textiles, for making up what are called “functional” articles.
