MULTI-PLY TISSUE PAPER PRODUCTS HAVING INTERNAL CTMP-PLY AND PRODUCTION THEREOF

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.
