Anvendelse af et overflade-reageret kalciumkarbonat i silkepapir, proces til at fremstille et silkepapirprodukt af forbedret blødhed, og deraf resulterende silkepapirprodukter med forbedret blødhed

摘要

The present invention relates to the use of a surface-reacted natural calcium carbonate as filler in tissue paper products, to a process to prepare tissue paper products, and to a tissue paper product featuring an improved softness, wherein said surface-reacted natural calcium carbonate is the reaction product of a natural calcium carbonate with an acid and carbon dioxide, which is formed in situ by the acid treatment and/or supplied externally.
