发明名称 METHOD FOR THE PRODUCTION OF TISSUE PAPER
摘要 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 volu me and the tear length is to be improved, with minimized freeness degree, su ch that the material suspension comprises lignocellulosic pulp of wood or an nuals, which has a tear length of more than 6.5 km at 12 °SR, or a tear leng th of more than 8.0 km at 15°SR, and a lignin content of at least 15% in rel ation 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% i n relation to the otro pulp for annuals in an unbleached state.
