STAINING PREVENTION METHOD FOR DRY PART OF PAPER MACHINE AND STAINING INHIBITOR USED FOR THE METHOD

摘要

A simple method capable of effectively preventing dry part areas, at least the surfaces of cylindrical dryers, from being stained even if a spray space is absent in a paper machine. The method can prevent the contact part of the dry parts (D) of the paper machine with a paper body from being stained. The dry part staining prevention method can continuously feed/apply a staining inhibitor (T) to the paper body (W) at a position just before the dry parts.
