ABSTRACT A process for producing a non-woven textile containing a bonding agent, and an adhesive on one side of the textile; in which the radiation polymerizable bonding agent is printed onto the textile from one side while the adhesive is printed on in the form of a powder by a powder-point or screen printing process from the other side. The printed textile is then subjected to irradiation from a mercury vapour lamp of which about 10 to 30% of the radiation is in the ultra-violet region for polymerizing the bonding agent. The remainder radiation serves to heat the material so that the particles of adhesive coalesce sufficiently to maintain their geometric shape distribution in the material. The material is subsequently dried, finished and the adhesive sintered. Using the screen printing process at least 95% of the particles in the powder are less than 0.1 mm in diameter, and using the powder-point process, 95% of the particles are less than 0.2 mm diameter.
