The object is achieved by a papermaking method using a papermaking felt made from abase 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).

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a papermaking method for using a papermaking felt for a papermaking machine, which is laminated on a wet paper by a felt of a paper machine. A felt for papermaking (hereinafter sometimes referred to as "felt") used for the drum, or the drum and the shoe to press the water in the wet paper. More specifically, it relates to a papermaking method for papermaking machine which can improve the water-wetting of wet paper, including the initial affinity period of the highest speed which is included in the paper machine to reach the stable production. . [Prior Art] In the papermaking process, in order to press water from wet paper, the paper machine has been conventionally provided with a wire portion, a press portion, and a drying portion. These wire portions, press portions and lay-up portions are arranged in the direction of the subtraction feed. . The wet paper side is successively delivered to the papermaking tool disposed on the wire portion, the press portion, and each of the sheets, the surface is conveyed and water is squeezed, and finally dried in the dried portion. In each of these parts, a plurality of press apparatuses for use in papermaking in accordance with the dehydrating function and in which the pressing and pressing parts of the press section are arranged in the direction of the thief are used. The end-shaped press-fitting system has an endless shape, or is connected to the paper machine to have an endless shape, and the two pieces of the yoke are placed together to sandwich the felt portion, spleen//, The upper and lower sides of the felt move in one direction...a# At the same speed, the surface of the 搬 Π 勃 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使 使29 201104039 . . -.. . . . ... ......

Y Further, in this type of paper machine, there is a roller press mechanism which is provided with a portion for pressing a portion of the felt which has been wetted with the roller and the roller and pressurizing at the same time in the press portion. The press device, in addition, is equipped with a shoe press: machine pants, which are pressed in the press section, and are pressed and pressed to hold the fg]. In the case of the press section of the paper machine according to the circle 1, the details are given. In the press section of Fig. 1, the left part of the wire is placed in the front part of the papermaking process, and the part of the wire which is located in the rear part of the papermaking process is divided into the pressed portion of the rear portion and the dry portion of the rear portion. The press section of Fig. 1 has a 4彳i-squeezing mechanism of a double-bar (tr_small shirt) in the form of a squeezed screen and is connected in series along the transport direction of the wet paper.

In the drum function, the work of dehydration from the thief (4) is not taken seriously, in order to transfer the water from the wet paper by the press-to-roller or the drum and the _ pressurize the water to the system. In addition, the appropriate space for the miscellaneous wealth of the miscellaneous goods, such as the availability of water, and the continuation of compressibility, are highly valued. When the rotation speed is stable, the == operation speed is stable early, and the production quantity is important. The machine 2 is the _ affinity period. Although the initial affinity period changes with the paper-making win=transfer, it is generally 1 ~2 days, the longest is about 5 days. /疋In the case of the non-drawing straight view conveying method represented by the tandem Nipco flexing paper machine, the running speed is also fast, and it is necessary to shorten the initial affinity period. From this point of view, various types of felts have been developed all the time. For example, in the case of the known method, after the completion of the enthalpy, a pressure is applied to the post-processing to increase the density (in order to increase the density). Adding S-going fruit will sometimes make it difficult to touch the roller that has been heated by the heat medium. In terms of the action mechanism, the volume of space generated by the shot is reduced, and the pressing force applied to the press section is easily transmitted to the wet paper. In the case of the surface-side, after the treatment with a polymer material, surface polishing is performed to make it compact, and the papermaking secret of this structure is dense from the beginning (four). Export the initial affinity period of the paper machine Shortening. However, the special purpose of the money, the polycarbonate, the amine, the acrylic resin, the epoxy resin, the phenolic resin or the polymerization of these compounds.

[PRIOR ART DOCUMENT] [Patent Document 1] [Patent Document 1] JP-A-2005-146443 (Patent Document 4) JP-A-56-53297 [Problem to be Solved by the Invention] The papermaking method of the papermaking machine of the well-known technique is short in the second-phase affinity period, but the thickness is thinned from the initial stage to reduce the spoon in the honey. Therefore, there is a problem that the door is crushed by the repeated pressurization which is received during use, and the thickness limit that can be used is early, and the period during which the wetting is sufficient can be sufficiently shortened. Further, in order to further reduce the space and increase the pressing force during the processing of the product, the fibers constituting the felt collide with each other, and the indentation is left at the interlacing point to cause a decrease in strength, so that there is a fear of hair removal or the like. DISCLOSURE OF THE INVENTION The present invention has an object of shortening an initial affinity period and solving the problem of ensuring such a reverse papermaking method during stable use. In particular, it is a problem to provide a papermaking method in which the following papermaking felt is used in a papermaking machine: a space volume in a felt which is ineffective in transferring wet or water pressure to wet paper which is pressed, from the beginning to the beginning The affinity is a suitable amount of space, so as to shorten the affinity period, the early water-passing caused by the dirt-free accumulation or excessive compaction of the felt for papermaking is reduced, and the water-squeeze caused by the lack of compressiveness is insufficient, and there is no The poor wet paper conveyance caused by no snakes, etc. is a mane for papermaking with a balanced basic function. 8/29 201104039 · · · · · · . . .

Further, as the mixture to be mixed with a polyhydric alcohol, a white: water-absorbent resin such as (iv) or pvA may be used, and it may be reacted with an isocyanate or the like.

In the case of the polyisocyanic acid vinegar, an aromatic, aliphatic or alicyclic polyisocyanate may be mentioned.

The means for containing the water-absorbent resin in the ruthenium is such that the aqueous solution is dispersed with a water-absorbent resin (4) moisture-containing coating cloth, blade coating, or the like. In order to keep the water-absorbent resin in a strong state, it is applied as needed by dispersing the agent in the aqueous dispersion, followed by twisting or illuminating the electron beam, and guessing it.

In addition, The coupling agent can be used to transfer the appropriate space volume other than the fiber formed by the initial::=1, from the start to the running speed to the highest speed region where the production can be stabilized and reach the end of use. Therefore, in view of the working conditions of the paper machine and the dehydration of the wet paper, the speed of the water-absorbed resin from the felt is controlled. The amount of m-weight depends on the moji of the absorbing base (active hydrogen) Mohr equivalent of the base. At that time, for 18/29 201104039, it can be adjusted with an appropriate molar equivalent ratio (_NC〇/_H).
