Abstract of the Disclosure The invention provides a process for the continuous, dry transfer of organic compounds, preferably of finishing and improving agents to a web of organic material, in particular to textile webs which contain synthetic fibres and are sensi- tive to contact pressure. The process comprises the following steps: (1) applying over the entire surface of an inert carrier such as a paper carrier or a strip of stainless sheet steel an organic compound e.g. a textile finishing agent, which is converted into the vapour state at atmospheric pressure above 80°C, preferably at 100°C to 220°C, (2) bringing said carrier into close alignment with the web to be treated in such a manner that each moves parallel to the other without coming into direct contact, (3) subjecting carrier and the web spacing between carrier and web being e.g. 0.5 to 5 mm to a heat treatment of at least 80°C in a closed heating chamber until the organic compound has been transferred to the web, and (4) transporting the treated web of material away again from the carrier. The invention also provides a suitable apparaturs for carrying out the above process.
