Abstract (en)
[origin: WO2008077450A1] The invention relates to a method for the production of a tissue web (1) produced from a material suspension comprising fibers. To this end, the volume and the tear length is to be improved, with minimized freeness degree, such that the material suspension comprises lignocellulosic pulp of wood or annuals, which has a tear length of more than 6.5 km at 12 °SR, or a tear length of more than 8.0 km at 15°SR, and a lignin content of at least 15% in relation to the otro pulp for coniferous wood in an unbleached state, or a tear length of more than 4.5 km at 20 °SR, and a lignin content of at least 12% in relation to the otro pulp for hardwood in an unbleached state, or a tear length of more than 3.5 km at 20 °SR, and a lignin content of at least 10% in relation to the otro pulp for annuals in an unbleached state.
