Abstract
The object of the invention is to provide a papermaking method using a papermaking felt in a papermaking machine, wherein the basic functions of the papermaking felt are well balanced, which does not have any wet paper web transfer deficiencies due to meandering, or the like, wherein free space volume of the 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. The object is achieved by a papermaking method using a papermaking felt made from a base material 5 and batt layers 6, 7 provided at least on the wet paper web carrying-side layer; wherein a water-absorbing resin 8 is included in the batt layers 6, 7 of the felt. The base material 5 may either have an endless shape, or an open-ended felt may be connected into an endless shape in a papermaking machine. The water-absorbing resin in the felt may either stay in the front batt layer 6 (Fig. 2), or it may also reach the base material 5 or the rear batt layer 7 (Fig.3).
