Abstract
The present invention relates to a process for manufacturing a thermobonding interlining in which dots of thermofusible polymer of mean thickness E are deposited on the front face of an interlining support, chosen from textile and non-woven supports, and one of the faces of the support is subjected to electron bombardment, wherein, as the dots of thermofusible polymer contain a radical activator and are bereft of photoinhibitor, the depth of penetration of the electrons in the dots of thermofusible polymer is adjusted in order to obtain a modification of the physico-chemical properties of the thermofusible polymer, chosen from the melting temperature and viscosity, over a limited thickness e with respect to the mean thickness E.
