Document Type and Number:

WIPO Patent Application WO/2018/061060

Kind Code:

A1

Abstract:

[Problem] To provide a contamination-preventing agent composition and a contamination preventing method so that even when the composition is applied only to a drier on the upstream side, a sufficient amount of the composition can be applied to a drier on the downstream side through wet paper, and pitch contamination in a plurality of driers can be prevented sufficiently as a whole. [Solution] The present invention relates to a contamination-preventing agent composition which is to be applied to driers D1-D8 in a dry part D of a papermaking machine, said composition comprising an emulsion, a retransfer agent and water, and having a cloud point of the retransfer agent of 55°C or higher and an HLB value of 8-15. Preferably the dynamic surface tension value of the composition at a lifetime of 100 msec according to the maximum bubble pressure method is 65 mN/m or less.
