  • Patent number: 9260819
    Abstract: A felt that further equalizes a pressure state under pressurization by a press so as to smooth the surface of a wet paper web without causing marking on the surface thereof and allow water to be uniformly squeezed out from the wet paper web without crushing the wet paper web is provided by a papermaking press felt wherein a difference between a maximum value and a minimum value of an interval between an upper knuckle portion and an upper knuckle portion, an interval between upper and lower knuckle portions, or an interval between a lower knuckle portion and a lower knuckle portion is arranged to be a value corresponding to 1.0 piece or less of an upper warp yarn in a base fabric.
    Type: Grant

    Date of Patent: February 16, 2016

  • Patent number: 8337670
    Abstract: A felt (10) for papermaking according to the present invention has a batt fiber layer comprising batt fibers contained in and integrally combined with a high-polymer elastic material (50). The batt fiber layer contained in the high-polymer elastic material (50) includes hydrophilic 1-methyl-2-pyrrolidone. The felt (10) for papermaking exhibits a hydrophilic capability as a felt structure from an initial phase of use. The felt has a sustained ability to be compressed and recovered for a long period of time and maintains water squeezing function, a wet paper web smoothing function, and a wet paper web feeding function until the end of the period in which the felt is used.

  • Publication number: 20070240844
    Abstract: A paper transporting felt includes a base layer, a first batt layer formed on a wet paper side surface of the base layer, a second batt layer formed on a press side surface of the base layer, a wet paper contacting fibrous layer including a plurality of split fibers split into fine fibers and a high polymer elastic material impregnating gaps between the fine fibers, and formed on a wet paper side surface of the first batt layer so as to allow the fine fibers and the high polymer elastic material to come into direct contact with the wet paper, and a hydrophilic nonwoven fabric layer disposed between the first batt layer and the wet paper contacting fibrous layer. In a surface of the wet paper contacting fibrous layer which comes into direct contact with the wet paper, the fine fibers are partially covered with the high polymer elastic material.
