The wet heat gelled resin is wet-gelled into a wet heat forming process in a molten metal atmosphere under a hot and humid atmosphere. [Embodiment] d In the present day and the month, <therefore, it is a gel which can be gelled in the presence of moisture. It is known that a wet heat gelling resin is used. The shape of the moist heat gelling resin may be a powder, a tip, a fiber or the like. In particular, the gelatinized resin is preferably fibrous. As the fibrous moist heat gelling resin (hereinafter referred to as "wet heat gelling fiber"), it is possible to use a wet heat gelling resin alone fiber or a wet heat gelling resin fiber component and other thermoplastic synthetic fiber components. Composite fiber (hereinafter referred to as "wet heat gelled composite fiber"). Thereby, the other fibers or at least other thermoplastic synthetic fiber components can maintain the fiber form, and the moist heat gelling resin can be gelated to function as a binder which can adhere the additives. Further, the additive may be adhered by a wet heat gelation resin fiber component or a wet heat gelled gel of a moist heat gelled resin attached to the surface of the fiber. Preferably, the additive is exposed and adhered. Further, the wet heat gelling resins and/or other fibers may be obtained by wet heat gelation of the resin fiber component or the wet heat gelation resin attached to the fiber surface 11 1296296 by wet heat gelation. fixed. Further, the fibrous formed article of the present invention can be molded into a molded article of a predetermined shape by wet thermoforming in a state where the fibrous structure is gelled in a metal mold. The form of the moist heat gelling resin may, for example, be powdery, pointed, or fibrous. In particular, in consideration of moldability, it is preferred to use a fibrous, that is, a wet heat gelled fiber. The gelation temperature of the wet heat gelling resin is preferably 5 〇 1 and the gelation temperature is 80 t or more. If it is used in a resin that is less than 5 (rc gelled, sometimes it may become difficult to adhere to a roller or a metal mold during gel processing, resulting in difficulty in the production of fiber structures and fiber molded bodies, or in midsummer or The high temperature environment cannot be used. Further, the so-called "gel processing" is a process of gelling a wet heat gelling resin. The wet heat gelling resin is preferably a vinyl-ethylene glycol copolymer resin. The reason is that Gelling by damp heat 'avoids deterioration of other fibers and/or other thermoplastic synthetic fiber components. The ethylene-ethylene glycol copolymer resin is a resin obtained by alkalizing ethylene-acetic acid ethyl acetate. The degree of alkalization is preferably 95% or more, and more preferably 98% or more. Further, the preferred ethylene content is 2 G mol% or more. Preferably, the ethylene is 50 mol% or less. More preferably, 7 γ is early. For the more detailed content of B, the content of acetamidine is 25 mol% or less, and the content of acetamidine is 45 mol% or less. If the degree of test is not full (4), there is adhesion (10) or metal mold (4). _The same is true, there are;: Second, Ethylene If there is a rate of 4, it will stick to the roller 12 1296296 or the metal mold at the time of the rubber reduction processing, which makes it difficult to produce the fiber-fiber structure and the fiber-shaped body. On the other hand, if it is said that the Ba Shiping 3 has When it exceeds 50% by mole, the wet heat gelation temperature becomes high, and the processing temperature rises to the vicinity of the melting point, and as a result, "the effect on the dimensional stability of the fiber structure and the fiber formed body is adversely affected. The preferred combination of the dimension and the other adhesive resin may be a composite fiber of the wet and thermal gelatinized resin fiber component and other thermoplastic synthetic fiber components;

When the content of the wet heat gelling resin fiber component is less than 〇% by mass, the addition tends to be difficult to adhere. When the content of the wet heat gelled resin fiber component exceeds 90 lbs and 1%, the fiber formability of the conjugate fiber is lowered. *

Further, the other thermoplastic synthetic fiber component in the wet heat gelled composite fiber may be a polyolefin, a polystyrene, a polyamide or the like, preferably a polydue smoke. When an ethylene vinyl alcohol-based copolymer resin is used as the component of the wet heat-gelled resin fiber, it is easy to form a composite fiber (combined fiber) composed of melt-spinning. Further, as the other thermoplastic synthetic fiber component, a thermoplastic synthetic fiber component having a melting point higher than that for hydrothermally gelling the resin fiber component; If the other thermoplastic & synthetic fiber component has a thermoplastic synthetic fiber component having a melting point lower than the temperature at which the gelation is formed, the other thermoplastic synthetic fiber component itself has a tendency to melt and harden, for example, when it is formed into a fiber formed body. It will become uneven with shrinkage. 14 1296296 The ratio of the Lichaothermal gelled composite fiber in the fiber structure is not particularly limited as long as it can adhere the additive, and the fiber is fixed by the gel and/or the additive is added. The ratio of the composite fibers required for effective fixation is preferably ίο% by mass or more. The ratio of the more preferable composite fiber is 30% by mass or more. The ratio of the excellent composite fiber is 5% by mass or more. For example, when the fiber structure contains a composite fiber, the fiber web exists on both surfaces, and other fibers are present inside; brother, the content of the fiber web containing the composite fiber.

It is also possible to form a gelled product on the surface of the composite fiber by wet-gelling the composite fiber into a wet heat gelling resin in the above form (m). Thereby, the adhesion effect of the additive can be further improved. Other fibers used in the above-mentioned form U) or form (IV) may be selected from chemical fibers such as rayon, natural fibers such as cotton, hemp, wool, etc., polyolefin resin 'f ester resin, polyfluorene. Any of a single or a plurality of synthetic resins such as an amine resin, an acrylic resin, or a polyurethane resin. In the case of the above-mentioned (four) uv), the wet heat gelling resin is preferably in a range of from i% by mass to 90% by mass based on the fiber structure. More preferably, the content is -3% by mass to 70% by mass. If the wet heat gelled resin contains the mass. /. I may have difficulty fixing other fibers by gelation, or θ!; the additive tends to be difficult to adhere. If the content of the moist heat gelling resin is ≥ 90% by mass, the fiber shape may disappear and become a film-like enamel additive which is buried in the gel. Any additive may be used as long as it is a particle. For example, 15 1296296 "Material: Inorganic particles are preferred.

Further, the water purification material using the organic-adherent particles as an additive is not limited to the non-woven fabric, and may be a water purification module in which the fiber bundle formed by the plurality of bundles of the additive-attached fibers is used as the organic adsorption portion. In addition, if the aggregate of the ruthenium-attachment-attached fibers is wound into a cylindrical shape, it may be used as a water purification filter when it is formed into a 17 1296296 fold. Further, when the cut structure is formed by a metal mold, the fiber structure Xe is preferably not cloth or cloth. In the case of non-woven fabric, the product is inexpensive to manufacture, and it is easy to obtain a deep-drawn molded body by containing moisture in the processing of Yitian.

The additive enters the interior of the fibrous structure, so it is preferred. The fiber or fiber structure to which 1 minute is imparted can be pressed by a squeezing roller or the like to be a predetermined moisture rate. / When the mixture is heated while the additive is dispersed, the gelation of the gelled resin is performed simultaneously with the moisture supply, so that only the concentration of the additive in the additive dispersion solution and the temperature at which the additive is heard are adjusted. To adjust the amount of adhesion of the additive. Specifically, the fiber or fiber structure is impregnated with hot water containing an additive (9 (rc or more) to attach the additive to the surface of the fiber. The fiber structure before the wet heat treatment may also be subjected to a hydrophilic treatment. In the case of the hydrophilic treatment, when the fibrous structure contains the hydrophobic fiber, the fibrous structure can be uniformly and uniformly supplied with water. As a result, the composite fiber is substantially uniformly wet-gelled, and the additive is likely to adhere, so that it is preferred. In the hydrophilic treatment, a surfactant treatment, an arc discharge or a glow discharge method, a plasma treatment method, an electron beam irradiation method, a γ-ray irradiation method, a photon method, a flame method, a fluorine treatment method, a graft treatment method, etc. may be mentioned.

Another side The better heat treatment temperature is below the melting point of the binder resin. The special heat treatment temperature is the bright point of the binder resin _ thief. If the wet heat treatment temperature is not full of the gelatinization temperature of the binder resin, sometimes it is impossible. The additive is effectively adhered to. If the wet heat treatment temperature exceeds the melting point of the resin of the binder, it is close to the refining point of the binder resin, so that the fiber structure may cause shrinkage when it is formed into a fiber structure. When the heating body is in contact, the surface pressure is preferably 0.01 to 0.2 MPa. More preferably, the lower surface pressure & Q • with Pa. The upper surface is higher than the upper limit A G. 〇 8 MPa. Also, is the t heating body a heat roller?

The upper limit of the hot roll line pressure is 2 according to this method' Instantly gels the wet heat gelled resin fiber component to thirst and simultaneously compresses the gelled product, so that the additive can be widely applied. According to this method, when wet heat gelation, the additive can be pressed in. Among the gels, the additive can be stronger The solid surface adheres to the surface of the fiber. The volume expansion and/or softness of the fiber structure is imparted: the wet fiber is formed by the helium gas treatment of the fiber containing the fiber and the wet heat gelling resin. The gelled resin is gelated to obtain an additive. The method of steam treatment is, for example, a method of blowing steam from above and/or below a fiber web. When hot pressing 20 1296296 steel is exposed to the tomb, the dimensional structure is applied to the condensing process. 2:=: square 2, there is no need for the fiber fiber structure to be more than m, *£ force.

[Month;] In the wet heat forming process, the crucible contains the fiber of the addition of the do not disperse solution, and the structure (4) the person-to-metal t (four) row is heated and pressurized. Heating in the state of moisture, the non-woven fabric itself will be moderately = long and easy to follow the shape of the metal mold, and it is easy to obtain a deep-drawn molded body. When the additive is heated as a dispersion solution, for example, the fiber structure can be obtained by Insert into a pair of metal molds and immerse them in hot water (9 (rc or more) to obtain a molded body. The wet heat forming process is performed under a humid hot atmosphere. The hot and cold forming processing temperature is above the gelation temperature of the gelled resin. ~ melting point - 2 (rc is better. The better wet heat forming processing temperature is 5 (^c or more. The preferred wet heat forming processing temperature is above 80 ° C. On the other hand, the better wet heat forming processing temperature is wet thermal gel Melting point of resin ·3〇°ς: below. Particularly good wet heat forming processing/severity is the melting point of wet heat gelling resin below -40 ° C. If wet hot forming processing 21 1296296 temperature is not full of wet heat gelling resin gel When the temperature is lowered, it is difficult to form a gelled product. If the wet heat forming processing temperature exceeds the dazzling point of the wet heat gelled resin, the melting point of the wet heat gelled resin may become uneven due to the melting point of the wet heat gelled resin. In the present invention, when the wet heat gelation resin is wet-gelled in a hot and humid atmosphere, it is preferred to perform a contact press forming process in a metal mold to produce a fiber molded body. The processing is a process of applying a pressure at which the fiber structure can be in contact with the metal mold. I is a so-called contact pressure, and the weight of the metal mold itself is applied when the fiber structure is in close contact with the metal mold, and the concept of pressure to the extent is included. Since the wet heat gelling resin is softened by gelation in a hot humid atmosphere, it is only a case of molding, and the molding pressure may not be made relatively high. In the fiber forming system, the fibers are fixed by gelation while maintaining the state of the fiber, so that a bulky and flexible molded body can be obtained. The metal mold is preferably a thin metal mold such as a stainless steel plate. It can also be a dense mesh-shaped metal mold. In the present invention, when the fiber molded body requires hardness or a wet-gelled resin is required to be rolled into a film-like gel, it can be used in the usual manner. The dusting force of the k-fiber molded body is subjected to heat and pressure processing. Next, the present invention will be described with reference to the drawings. Figs. 1A to 1C are cross-sectional views showing the additive-attached fibers according to an embodiment of the present invention.

[Water quality purification test method]

For Examples 13 and 14 and Comparative Examples 3 and 5, the water purification performance test was carried out using the water-floating type simple tester shown in Fig. 6. As shown in Fig. 6, the water circulation type simple tester 2 is a bottomed cylindrical container which is fixed to the pedestal 21 by a pedestal 2 1 and fixing jigs 22a and 22b attached to the pedestal 2 1 by a fixing jig 22a. 23. A pump 24 that circulates water within the vessel 23. The pump 24 is provided with a tube 2A to which the bottom opening 23a of the container 23 is attached, and a tube 24b fixed to the pedestal 21 by the fixing jig 22b, and sucks the water in the container 23 from the opening 23a of the container 23, thereby attracting The water is discharged to the upper portion of the container 23 by the tube 24b. Further, in the present experiment, in Example 13 and Comparative Example 5, factory waste water having a chemical oxygen demand of 40 ppm was injected into the vessel 23, and factory waste water of 2 〇 PPm was injected into Example 14 and Comparative Example 3. Further, by controlling the circulation flow rate of water to 6 liter/min by the electric power adjusting device (not shown) connected to the pump 24, the amount of the factory waste water in the container 23 was maintained at a high level during the test.

Next, for the examples ', , and the comparative example 3'5', the small amount of the scaled piece 25 was put into the commercially available tea bag 26 (see Fig. 6). Zero photo 6). Further, in the water purification performance test, as shown in Fig. 6, the test sample 27 was immersed in the container U: 'factory waste water, and the metal wire 28 was fixed to the fixing jig 22b. 41 1296296 [C 0 D Concentration measurement method] The COD concentration system collects the factory wastewater in the container 23 into the flask in a dropper every time during the measurement, and uses the simple water quality analysis product "packaging test machine" (WAK-COD, measuring range) manufactured by the Institute of Synthetic Chemistry. 0 to 100 mg / liter) to measure color with the standard color. The results are shown in Table 8. Table 8 C0D Concentration (ppm)~~----- After initial concentration of 10 minutes, after 15 minutes, after 30 minutes, after 60 minutes, after 120 minutes, Example 13 —--- 40 30 " 30 28 16 — Example 14 20 '— 20 13 "Ϊ3-10 Comparative Example 3 20 — 20 20 20 20 Comparative Example 5 40 35~ 30 30 T8 ~ —

[Results] As shown in Table 8, in the case of using the non-woven fabrics of Examples 13, 14, compared with Comparative Examples 3 and 5, the COD concentration was decreased rapidly, and good water purification performance was exhibited. In particular, after 2 minutes from the start of the measurement, the COD concentration of Example i 4 became half of the concentration of c〇D of Comparative Example 3, and the water purification performance was improved. This is considered to be because the activated carbon particles (organic adsorbent particles) in the non-woven fabric of Example 14 are adhered by the moist heat gelation gelled by the surface of the fiber, and the organic adsorbent particles are exposed to the surface. The adhesion was suppressed, and the decrease in the specific surface area of the organic adsorbent particles was suppressed as compared with the comparative example. [Activated carbon shedding rate] The non-woven fabrics of Example 14 and Comparative Example 5 were cut so that the amount of activated carbon became 1.2 1 g. The size of the cut sample, Example 14 was 42 * 1296296 3 0 cm x 2 Ocm, and Comparative Example 5 was 6.6 cm x l〇cm. Next, 2 liters of water was placed in a 3-liter flask. The above-mentioned samples of Example 13 and Comparative Example 5 were placed in water in a flask, and stirred with a magnetic stirrer for 4 hours. After that, the sample was taken out, and the residual liquid in the flask was filtered by a glass filter paper (manufactured by Toyo Filter Co., Ltd., trade name "Ade Bang Tike", catalogue "GLASs FIBER GS25", diameter 47 mm). The filtered glass filter paper is dried, and then the quality of the dried glass filter paper is measured. Then, the amount of the activated carbon and the shedding rate were calculated from the mass of the obtained glass filter paper. Further, the amount of active slaves is the mass of the dried glass filter paper minus the value obtained by filtering the quality of the glass filter paper. Further, the shedding rate of activated carbon is the amount of activated carbon which is divided by the amount of activated carbon before the test (121 g) and multiplied by 1 〇〇. The results are shown in Table 9. Table 9 Amount of activated carbon (g) Amount of shedding (g) Shedding rate (g) Example 14 1.21 0.0016 0.13 Comparative Example 5 1.21 0.0201 ----- 1.66 [Results] As shown in Table 9, the nonwoven fabric of Example 14 Compared with the non-woven fabric of Comparative Example 5, the amount of seizure of activated carbon and the shedding rate were suppressed. This is considered to be due to the fact that the activated carbon (activated carbon particles) in the nonwoven fabric of the manufacturer 4 is fixed by the wet heat gelation of the surface of the fiber, and the test can be carried out in Comparative Example 5, and the activity is Carbon can remain stronger for the sake of it. 43 1296296 [Example 15] (Preparation of non-woven original board) The sheath component was prepared as an ethylene-vinyl alcohol copolymer resin (EVOH, ethylene content: 38 mol%, melting point 176. 〇, core component was polypropylene (pp, melting point 161°) C) EVOH: core-sheath type complex 5 fiber (denier ··2.8 dtex, fiber length: 51 mm) with a ratio of pp of 50 ·· 50 (the fiber length: 51 mm).
