    • PROBLEM TO BE SOLVED: To provide a papermaking felt, wherein the basic functions are well balanced, which does not have any wet paper web transfer deficiencies due to meandering, or the like, wherein free space of a felt, in which the effect of the press pressure and the hydraulic pressure is scarcely conveyed to the wet paper web, is set to the suitable amount for the initial warming-up period from the start so that the initial warming-up period is shortened, and wherein water squeezing does not deteriorate due to premature decline of water permeability and due to the inability to maintain compressibility by excessive compaction and accumulation of dirt. SOLUTION: The papermaking felt is made from a base material 1 and batt layers 2, 3 provided with at least a wet paper carrying-side layer, and a water absorbing resin 4 is included in the felt. The base material 1 may be applicable to either one of an endless shape or one with an endless shape made by connecting open-ended felts on a papermaking machine. The water-absorbing resin in the felt may either stay in the front batt layer 2 (Fig.1), or it may reach the base material or the rear batt layer 3 (Fig.2). COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提供一种造纸毡,其中基本功能是良好平衡的,其不会由于曲折等而导致任何湿纸幅转印缺陷,其中毡的自由空间,其中 冲压压力和液压几乎不被输送到湿纸幅的效果从起始开始被设定为初始预热期间的合适量,从而缩短初始预热时间,并且其中挤压 由于透水性的过早降低和由于过度的压实和积聚而不能保持压缩性而不会劣化。 解决方案:造纸毡由基材1和至少设置有湿纸携带侧层的絮垫层2,3制成,并且吸水树脂4包括在毡中。 基材1可以适用于通过在造纸机上连接开口毛毡而制成的环形形状或环形形状中的任一种。 毛毡中的吸水树脂可能会停留在前毛层2(图1)中,或者可能到达基材或后毛层3(图2)。 版权所有(C)2011,JPO&INPIT
