ABSTRACT:
An improved dry process for the finishing of organic material, particularly textile material made from natural or synthetic organic fibres ist described, which comprises applying to an inert carrier preparations containing at least one textile finishing agent transferring at atmospheric pressure above 80.degree.C to the organic material, optionally a bonding agent stable below 250.degree.C, water and/or an organic solvent; drying of the said preparation; bringing into contact then of the treated side of the inert carrier with the surface of the organic material to be finished; subjecting thereupon of carrier and the material to be finished, optionally under mechanical pressure, to a heat treatment at a temperature of at least 80.degree.C until the said textile finishing agent has transferred to the material to be finished, and separating of the finished material from the carrier.
The advantage of the new process is that, since there is no effluent produced, it is possible to use also textile finishing agents which are not biologically decomposable and it offers the possibility of obtaining finishing effects on the inside which differ from those on the outside surface of a fabric, such as is desired in the practice.
