摘要： Methods for reducing or inhibiting deposition on or within press felts to increase the effective life of the press felt and reduce or eliminate the need for batch cleaning are disclosed. The methods disclosed treat press felt while paper is being produced with compositions containing at least one enzyme. Additionally, the enzymes can be applied in combination with other non-enzymatic felt conditioning products either by blending and applying at the same application point or by applying the enzyme and the non-enzymatic felt conditioning product at two different locations along the felt. The treatments are applied continuously or intermittently.

摘要： Disclosed is a method of improving the release of paper webs from the surface of press rolls or other paper making or converting equipment by applying to such a surface non-aqueous, non-curing hydrocarbon polymer compositions. The non-curing hydrocarbon polymers have the formula (CH3)3C—[—C(R1)(R2)—C(R3)(R4)—]n—C(R5)═C(CH3)2 (I) wherein R1 through R5 are hydrogen or —CH3, with at least one of R1 through R4 being —CH3, and n is such that the number average molecular weight of such hydrocarbon polymers is from 50 to 3000. They may be hydrogenated. Preferred non-curing hydrocarbon polymers are polybutenes of the formula (CH3)3C—[—CH2—C(CH3)2—]n—CH═C(CH3)2 (II). Preferred compositions comprise at least one such hydrocarbon polymer component having a number average molecular weight from 400 to 700 and a second such component having a number average molecular weight of 100 to 400. The compositions are applied to the equipment surface in the absence of water.
