<p>Thermally fusible prod. comprises a textile substrate; points of thermally fusible polymer distributed on one side of the substrate, and chemical material for acting on the polymer to modify its chemical structure at least at its interface with the substrate to prevent flow of the polymer through the substrate under action of heat, pressure or steam. The chemical material comprises heat curable amino aldehyde prods., usea formols or melamine formols as reactive material that reacts with the polymer in presence of stimulator, assurer or promoter and acid catalyst, ammonium salt or Mg salt. Alternatively, the reactive material is e.g., epoxy function modified polymer</p> |
