Abstract
This invention provides a process for the dry thermal transfer of organic compounds, preferably of textile finishing agents, onto webs of organic materials, in particular textile webs and carpets, by means of needle-bearing supports. The process comprises the following steps: 1. applying of a preparation which contains a transferable organic compound to the needle side of the support 2. bringing said needle side of the support into contact with the web, whereby support and web rest against one another, 3. subjecting the support and/or the web to heat until the compound has transferred under atmospheric pressure to the web 4. separating the treated textile web from the support. The invention also provides a suitable apparatus for carrying out said process.
