Verfahren zur Applikation von Behandlungschemikalien auf flächige Erzeugnisse auf Faserbasis, insbesondere Tissue, und damit hergestellte Produkte

摘要

The present invention relates to a method of applying treatment chemicals to a fiber-based planar product, particularly tissue, said method comprising the steps of: a) producing a suspension of frozen particles of a composition that contains at least one treatment chemical in a fluid inert medium exhibiting a temperature at which the treatment chemical is present in a frozen state, b) applying the suspension made in a) to the planar product, c) removing the fluid medium remaining in the planar products in order to keep the frozen particles in the planar product, and d) increasing the temperature above the melting point of the particles from the treatment chemical, as well as an apparatus usable for this method and a fiber-based planar product obtainable by this method. The method of the invention is particularly suitable for the application of treatment chemicals having chemical or physical properties which are difficult to bring into harmony, when applying these chemicals.
