利用効率を高めている。2. Description of the Related Art Conventionally, as this type of water purifier cartridge, for example, there is a cartridge as disclosed in Japanese Patent Application Laid-Open No. 1-262883. The water purifier cartridge has an inner case in which a hollow fiber membrane fiber bundle is housed in a U-shaped state. Hollow bent in U-shape
Both ends of the fiber membrane fiber bundle are supported by being potted at the inner case opening, and the inner holes of the respective hollow fiber membrane fibers communicate with the outside of the inner case. This water purifier cartridge, as described above, bends the hollow fiber membrane fiber bundle into a U-shape and potts both ends at the same time, thereby streamlining the potting operation and improving the utilization efficiency of the hollow fiber membrane fiber. Is increasing.

ある。It is desired that a water purifier cartridge be small in size and have high filtration performance (capacity). In other words, how many hollow fiber membrane fibers are arranged and used in a small capacity. However, in the conventional water purifier cartridge hollow fiber membrane bundle simply bent into U-shape accommodated in the inner case, in which is housed inside casing
Since the filling rate of the empty fiber membrane bundle does not increase, it is difficult to realize a water purifier cartridge that is small and has high filtration performance.

The hollow fiber membrane fibers located inside the U-shaped hollow fiber membrane fiber bundle are broken and broken, or the hollow fiber membrane fibers located outside the U-shaped fiber bundle are disturbed by abrasion friction when the inner case is inserted. Because it is easily damaged, productivity is very poor. (2) Further, if the filling rate of the hollow fiber membrane fiber bundle exceeds 50%, production becomes almost impossible. Here, the filling rate (%) of the hollow fiber membrane fiber bundle is defined by the following equation. Filling rate (%) = volume of hollow fiber membrane fiber bundle × 100 / volume of inner case

The bending action due to the increase in the filling factor of the empty yarn fiber can be avoided by twisting the fiber bundle . That is, in the conventional example shown in FIG. 3, the fiber as shown in FIG.
Since the bundle is simply bent into a U-shape as shown in FIG. 3B, the hollow fiber membrane fiber 10a located inside the U-shaped hollow fiber membrane bundle 10 is compressed. Be folded. In contrast, in the present invention shown in FIG. 1, as shown in the diagram (a)
A bundle of many hollow fiber membrane fibers aligned in one direction
Since it is twisted around the bundle core as shown in FIG. 3B and bent in a U-shape as shown in FIG. 3C, the pressure due to the increase in the filling factor is dispersed, and the hollow fiber membrane is formed. Fibrous breakage can be prevented. In addition, both ends of the fiber bundle after bending
Is supported and fixed by potting as in the prior art.

Not practical. In Conventional Example 2, the initial filtration flow rate and the turbidity filtration capacity both satisfy the target values for the time being, but the damage / pressure loss rate of the hollow fiber membrane fibers is somewhat high. In Conventional Example 3, although the initial filtration flow rate and the turbidity filtration ability are both good, the hollow fiber membrane
Since the filling rate of the fiber bundle has increased, the damage / pressure loss rate of the hollow fiber membrane fiber is high, and the productivity is poor. In contrast to these conventional examples, in Examples 1 to 6, the filling rate of the hollow fiber membrane fiber bundle is higher than that of the conventional example, the initial filtration flow rate and the turbidity filtration capacity are both large, and the hollow fiber membrane fiber bundle is , The damage and pressure loss rate of the hollow fiber membrane fiber is small and the productivity is good. In addition, even if the length of the hollow fiber membrane fiber bundle itself after being twisted is the same, as the twist angle increases, the length of the hollow fiber membrane fiber can be increased,
As the twist angle increases, the filling rate of the hollow fiber membrane fiber bundle increases.

ある。As is apparent from the above description, according to the first aspect of the present invention, the hollow fiber membrane fiber bundle is bent into a U-shape while being twisted, and the inside of the cartridge is formed. Since it is stored in the case, the pressure applied to the hollow fiber membrane fibers when bent into a U-shape is dispersed, and the hollow fiber membrane fibers are extremely unlikely to be damaged. Further, by twisting the hollow fiber membrane bundle, the convergence of the hollow fiber membrane bundle is increased, there is no thread disturbance, easily inserted into the case, even breakage of the hollow fiber membrane fibers by abrasion during insertion To reduce. Furthermore, by twisting the hollow fiber membrane bundle , the filling rate of the hollow fiber membrane fiber that can be accommodated in the inner case of the same volume increases, realizing a water purifier cartridge that is small and has high filtration capacity. It is also possible.
