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 sensitive 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.degree.C, preferably at 100.degree.C to 220.degree.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.degree.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. |
