Conventionally, the common method for hardening fiber bundles is to immerse the fiber bundles in a resin solution of a desired concentration, then squeeze out the resin solution using a nozzle or the like to set the desired resin concentration, and then heat and dry the fiber bundles. A method is known in which the filling of an ink absorber is made by causing irregular bonding between fibers within a fiber bundle, but this method has the following drawbacks. That is, the resin tends to adhere densely to the parallel portions between the fibers, significantly reducing the intertwining portions between the fibers within the fiber bundle, which is an important function of batting. Furthermore, since the fibers pass through the resin solution, there is a problem in that even after the heating and drying process, a small amount of residual solvent remains in the fiber bundle and causes a chemical reaction with ink or the like. Furthermore, the resin concentration changes due to evaporation of the solvent during the manufacturing process, making it difficult to obtain stable quality.

None of the above-mentioned conventional methods for producing fiber bundles for writing instrument cores or ink absorbers, cigarette filters, or the above-mentioned absorbing and emitting bodies or water supply pipes include the step of adding additives; Multiple types of fibers were bonded together by melting the fibers themselves. The degree of crimp of ordinary staples for spinning is low, and because of the elongated state during the processing process, there are many adhesion areas rather than interlacing points. In this way, the fibers are bonded to each other with few intertwining points and many solid fused parts, and the inner part of the fiber bundle has fewer voids, resulting in a lower ability to retain liquid or gas. , there is a risk that so-called bottling may occur.
