Abstract
The textile support for thermo-bonding interlining according to the invention is constituted by a weft knit, composed exclusively of yarns of biodegradable cellulosic matter, particularly viscose, the warp being exclusively of continuous multi-filament yarns. The support was preferably subjected, prior to the application of the thermo-fusible polymer spots, to a treatment of mechanical compacting by passage between a heated cylinder and a compression belt, the temperature of the cylinder being at the most 130.degree. C. The thermo-bonding interlining, comprising the textile support mentioned above, after application of the spots of thermo-fusible polymer, was advantageously subjected to a second treatment of mechanical compacting, similar to the first, the cylinder being heated only to a temperature less than 80.degree. C.
