A METHOD OF APPLYING TREATMENT CHEMICALS TO FIBER-BASED PLANAR PRODUCTS AND PRODUCTS MADE USING SAME
The present invention relates to a method of applying a treatment composition containing at least one treatment chemical to a fiber-based planar product, said method comprising the steps of: a) applying the treatment composition to one side of the planar product, and b) allowing the treatment composition to penetrate the planar product at least in part, said treatment composition being heated before and/or during step b), wherein the penetration of the treatment composition preferably is promoted by applying a subatmospheric pressure at that side of the planar product not treated with the treatment composition; as well as a device usable for this method and a planar fiber-based product, in particular tissue, obtainable thereby.
