    摘要: The disclosure pertains to a multilayered web-type tissue product with at least three partially interconnected layers, namely, two optionally embossed outer layers containing predominantly chemical pulp and at least one optionally embossed inner layer containing predominantly HTCTMP/CTMP; other mechanical pulp and/or chemical pulp-fibres, chemically stiffened or cross-linked within the fibre wall so as to reduce considerably the hydrogen bonding capacity of those fibres when wet, can also be used. The tissue product is characterised in that only the outer layers contain a quantity of wet strength additive equivalent to 0.1 - 10 wt.% of the base tissue. Also disclosed is a process for manufacturing a multilayered web-type tissue product with at least three partially interconnected layers, namely, two optionally embossed outer layers containing predominantly chemical pulp and at least one optionally embossed inner layer containing predominantly HTCTMP/CTMP, in which other mechanical pulps and/or chemical pulp-fibres, chemically stiffened or cross-linked within the fibre wall to reduce considerably the hydrogen bonding capacity of those fibres when wet, can also be used.

    摘要: The present invention relates to a method of applying a treatment composition to a fiber-based planar product, in particular tissue, said method comprising the steps of: a) producing particles from a frozen treatment composition containing at least one treatment chemical, c) applying the frozen particles of the treatment composition to the planar product, d) heating the frozen particles of the treatment composition to the melting point of the frozen treatment composition or to a higher temperature, 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.
