  • Printing blanket and method of manufacturing the same
    Patent number: 5294481
    Abstract: A printing blanket including a base fabric and a surface layer in a laminated structure wherein a surface reforming agent containing a perfluoroalkyl group is applied to the surface layer such that a critical surface tension ranging from 10 to 16 dyn/cm appears on the surface of the surface layer is disclosed. To practically manufacture a printing blanket of the foregoing type, there is also disclosed a method wherein a compressible layer is placed on a base fabric, a surface layer is then placed on the compressible layer thereby to form a laminated structure with the base fabric and the compressible layer, and thereafter, a surface modifier containing a perfluoroalkyl group is applied to the surface layer such that a critical surface tension ranging from 10 to 16 dyne/cm appears on the surface of the surface layer. It is preferable that the surface layer is molded of a compound based on a nitrile butadiene rubber.
