Method for the production of tissue paper
First Claim
1. A method for the production of a tissue paper web, which is produced from a pulp suspension comprised of fibers, said pulp suspension having a refining degree of less than 21°
- SR and being of such condition that it is possible to produce from said pulp suspension a laboratory sheet according to TAPPI 205 SP 95 (Rapid Kö
then) whose breaking length measured according to TAPPI 220 and TAPPI 494 at at least a specific refining degree (RDspecific) is selected from a refining range from 15°
SR to less than 21°
SR, is greater than or equal to the value resulting from 0.55(km/SR)*(RDspecific−
10°
SR).

Abstract
A method for the production of a tissue paper web, which is produced from a pulp suspension comprised of fibers, the pulp suspension having a refining degree of less than 21° SR and being of such condition that it is possible to produce from said pulp suspension a laboratory sheet according to TAPPI 205 SP 95 (Rapid Köthen) whose breaking length measured according to TAPPI 220 and TAPPI 494 at at least a specific refining degree (RDspecific) is greater than or equal to the value resulting from 0.55(km/SR)*(RDspecific−10° SR), whereby the specific refining degree is selected from a refining range from 15° SR to less than 21° SR, in particular 15° SR to 19° SR.

71. A method for the production of a pulp suspension comprised of fibers, with which at least one suspension fraction is produced with the following steps:
-
providing a high-consistency feed pulp suspension comprised of fibers and having a consistency of more than 20% and a refining degree of less than 15°
SR; and
refining the high-consistency feed pulp suspension to a refining degree of 15°
SR or more to obtain the suspension fraction. - View Dependent Claims (72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90)
