いた。Furthermore, Japanese Utility Model Publication No. 1-35278 discloses a structure in which a bundle of compressed fiber threads is formed into a bundle, and the bundle is rolled up into a ball shape by squeezing approximately the center. An example of its use as a material is disclosed. Conventionally, a mechanical method such as rolling the bundle on a belt conveyor has been used to roll the tied bundle into a ball shape having a shape similar to that shown in FIG.

When they are used as contact materials, they have the disadvantage that sludge formation and frog removal are planar, and their performance is not as good as that of three-dimensional ball-shaped structures.

形状が崩れたり、水処理の性能としても問題があった。Furthermore, since the mechanically formed structure is mechanical, the force to roll it into a ball is strong on the surface, and even if the external shape is a ball, the fibers are uniform in three dimensions up to the internal structure. The target interaction was not sufficient. Therefore, the shape may collapse during use, and there are problems with water treatment performance.

ような潜在的捲縮繊維であっても良い。The fibers of the present invention may be natural fibers or synthetic fibers, as long as they have crimps or potentially have crimps.
By way of example, fibers of vinyl chloride, vinylidene chloride, polyamide, polyester, urethane or polypropylene synthetic resins can be used. In particular, vinylidene chloride resin fibers are suitable because they have excellent durability and sludge adsorption properties. Therefore, the crimped fibers of the present invention may be not only crimped fibers that have already been crimped, but also potentially crimped fibers that develop crimps during a heat treatment process.
また、潜在的捲縮繊維を用いて製造工程の中の別のとこ

Examples of processed yarns include crimped yarns, woolly processed yarns, etc. Preferably, short fibers can be used by spinning. Note that the cross section of the fiber is not limited to a circular shape, and may be oval, rectangular, triangular, hollow, or the like.

のが適当である。The crimp ratio of the fibers is preferably in the range of 10 to 300%, more preferably 20 to 200%. If the crimp ratio is less than 10%, the crimp is too small and sufficient intertwining of the fibers cannot be obtained.On the other hand, if the crimp ratio exceeds 300%, the fibers become too coiled and the fiber density does not increase and the ball-like structure becomes difficult to form. In addition to crimp, it is preferable to use fibers that have the property of heat shrinking during the heat treatment process, since the surface area will be greatly tightened due to control, resulting in a structure with a more uniform fiber density as a whole. In this case, the heat shrinkage rate of the fiber is in the range of 5 to 50%. Furthermore, the degree of crimping of the crimped fibers is generally from 1 to 25 times/inch.

ール状構造体が容易に製作される。The bundle of the present invention can be exemplified by pulling or spinning 100 to 100,000 of the crimpable fibers having a thickness of 0.1 to 1000 deniers. It may be a bundle or a mixture of fibers of different materials. In the case of crimped fibers, it is preferable to apply tension to the bundle to the extent that the fibers become almost straight. This is because when the tension applied to the bundle is released by cutting the bundle, the fibers bounce back and intertwine in a complicated manner, and the bundle of fiber bundles approaches a ball shape. be. As a guideline for the tension to be applied to the bundle, it is in the range of 1 to 500 l11g/denier.6 Next, as the binding material used in the present invention, garlic or string made of metal such as aluminum or iron, or plastic. In addition to the type of binding fixture, known binding means may be employed, such as binding with adhesive or heat fixing. As the binding means in the case of heat fixation, high frequency heating means and ultrasonic heating means are suitable. The above-mentioned fixed intervals for binding the bundles with the binding material should be appropriately windowed so that a ball-shaped structure of a given size is formed, but the method and apparatus of the present invention Ball-shaped structures of 0.5 to 30 CO+ are easily fabricated.

出来る。The heat treatment of the bundled fiber bundle is carried out at a temperature below or close to the processing temperature at the time of crimping for crimped fibers, and at a temperature at which the above-mentioned crimp rate can be achieved for potentially crimped fibers. Examples of suitable heat treatment methods include rotary kiln heating, fluidized bed heating, air flow conveyance heating, etc., as well as methods of heat treatment in a liquid, such as hot water or boiling water.

べきことである。By heat treatment, the latent crimped fibers develop all or part of the crimps, and the crimped fibers recover from the elongation of the crimps caused by the tension during the bundling and cutting process. The force in the shrinking direction may be applied to roll it into a ball. This force is further strengthened in heat-crimpable fibers. Therefore, it is surprising that we were able to mold a structure with excellent properties as described below.

ボール状構造体を提供することができる。[Effect 1] The method and apparatus for manufacturing a ball-shaped structure according to the present invention utilizes the shrinkage force of the fibers due to heat treatment to form the bundled fiber bundle into a ball shape, so that the fiber density is uniform throughout the structure. Accordingly, it is possible to provide a ball-shaped structure suitable as a contact material in which fibers extend radially from a binding material located at the center in a complicated manner.
また、得られるボール状構造体は、真珠性がよく、強度

の中間を切断して本発明の束状繊維結束体Ｃを得た。First, an aluminum wire with a diameter of 2.5 mm was passed through the binding means 3 and clipped one by one at intervals of 6 cwl.Next, the V-shaped gear 6 was used to apply tension to the extent that the fibers were uncrimped and became almost straight, and the clips were held together. A bundle-like fiber bundle C of the present invention was obtained by cutting the fiber bundle C in the middle.
そして、この束状繊維結束体Ｃを熱処理手段１３に供給
し、９０〜１１０℃の温度で熱処理して本発明のボール

での平均の滞留時間は、約６０秒であった。Then, this bundled fiber bundle C is supplied to the heat treatment means 13 and heat treated at a temperature of 90 to 110°C to obtain the ball-shaped structure of the present invention. The average residence time was about 60 seconds.
得られたボール状構造体は、内部まで繊維密度が均一で
あり、真球度、強度も申し分のないものであった。更に
、水処理用接触材としての評価も好ましいものであった
。The resulting ball-shaped structure had uniform fiber density throughout, and had perfect sphericity and strength. Furthermore, the evaluation as a contact material for water treatment was also favorable.
［試験例−２１
試験例−１で作成された束状繊維結束体Ｃを沸騰水中に
１０分間投入する熱処理操作を行なったところ、試験例
−１同様の優れたボール状構造体が得られた。[Test Example 21 When the bundled fiber bundle C produced in Test Example 1 was subjected to a heat treatment operation of immersing it in boiling water for 10 minutes, an excellent ball-shaped structure similar to Test Example 1 was obtained. .
本発明によるボール状構造体の製造方法およびその装置
によれば、捲縮性繊維を用いているため、束状繊維結束
体がボール状に成形される過程で繊維は縮みながら丸め
られる。従って、構造体全体にわたって、特に中心部で
も繊維密度が均一で、繊維が中心に位置する結束材から
放射状に繊維に絡み合って外に延びている接触材として
好適なボール状構造体を成形することができる。According to the method and device for manufacturing a ball-shaped structure according to the present invention, since crimpable fibers are used, the fibers are shrunk and rolled in the process of forming the bundled fiber bundle into a ball shape. Therefore, it is possible to form a ball-shaped structure suitable as a contact material in which the fiber density is uniform throughout the structure, especially in the center, and the fibers extend outward from the binding material located at the center by intertwining with the fibers in a radial manner. I can do it.
また、このボール状構造体は、真珠性がよ（、強度的に
も優れたものであるため、それを処理槽に充填したとき
最密充填となり、繊維密度の均一性とあいまって接触効
率、通水性等に優れているという効果もある。In addition, this ball-shaped structure has excellent pearl properties (and strength), so when it is filled into a processing tank, it becomes a close packing, which, together with the uniform fiber density, improves the contact efficiency. It also has the effect of being excellent in water permeability.
