Fiber web manufacturing method

The present invention relates to a method for manufacturing a fibrous web， such as a web of paper， board， tissue， and the like. This method comprises the steps of obtaining at least one fiber suspension of lignocellulosic and/or cellulosic fibers， and the fiber suspension as an intermediate residence entity， such as a pulper， storage tower or broke tower. tower). The fiber suspension comprising bacterial endogenous spores is released through the outlet through the outlet after a residence time of at least 2 hours in the intermediate residence period， and after the delay time， the fiber suspension is formed into a fibrous web. Bacterial endogenous spores are sensitized by adding a germination surfactant comprising a primary or secondary ammonium head group and a linear unsubstituted C12-alkyl tail to the fiber suspension at the point of addition， which point of addition is the lower of the intermediate retention period. part) or after the outlet of the intermediate residence， but before the formation of the fibrous web. The invention relates to a method for manufacturing a fibrous web， such as web of paper， board， tissue or the like. The method comprises obtaining at least one fibre suspension of lignocellulosic and/or cellulosic fibres and feeding the fibre suspension into an intermediate residence entity， such as pulper， storage tower or broke tower. Fibre suspension， which comprises bacterial endospores， is discharged out of the intermediate residence entity via an outlet after a residence time of at least 2 hours in the intermediate residence entity and after a time delay the fibre suspension is formed into a fibrous web. Bacterial endospores are sensitised by adding a germinant surfactant， which comprises a primary or secondary ammonium head group and a linear unsubstituted C12-alkyl tail， to the fibre suspension at an addition point， which is located at the lower part of the intermediate residence entity or after the outlet of the intermediate residence entity， but before the formation of the fibrous web.
