大掛かりとなる。フラッシュ紡糸法は適用できる樹脂の
種類は多いものの、短繊維状のものしか出来ず、連続繊
維化が難しい。Various proposals have been made regarding bundles of ultrafine fibers having a diameter of several hundred microns or less and techniques for producing them. For example, ultra-fine fibers are manufactured using a super draw method (such as JP-B No. 28-617), a flash spinning method (such as JP-B No. 35-11851), or a jet spinning method, and then a large number of ultra-fine fibers are bundled using a binder. method, or method of mechanically twisting and converging (in the case of ultrafine fibers,
This method is practically difficult). However, when using the super draw method, the types of resins that can be used are limited and a special stretching process is required after spinning, resulting in large-scale equipment. Although the flash spinning method can be applied to many types of resin, it can only produce short fibers, making it difficult to make continuous fibers.

るためには特殊な二次加工が必要であるのだが、極細繊
維の二次加工は繊維強度が弱いので非常に難しい。Furthermore, since the solvent is scattered during the flashing step, this is not a preferable method from the viewpoint of safety and working environment. Jet spinning requires a specially shaped spinneret and has the same problems as flash spinning. Above all, these methods require special secondary processing to produce fiber bundles, but secondary processing of ultrafine fibers is extremely difficult due to their weak fiber strength.

初めて極細繊維束が得られるのである。For this reason, we developed a technology that uses two types of resins to spin fibers with an island structure, and then extracts and removes the resins, leaving behind ultrafine fibers of the islands, to produce fiber bundles. Force Z has been proposed as a bolima blend fiber dissolution method or a polymer mutual array fiber dissolution method. However, in many polymer blend fiber melting methods, the longitudinal length of the resin forming the islands is short, making it difficult to form continuous fibers. Among them, as seen in Japanese Patent Publication No. 44-21167, an attempt to make continuous fibers by this method has been proposed.C1 The resulting ultrafine fiber bundle is a complex network-like tangle and sag. . On the other hand, the latter polymer mutual array fiber dissolution method (
Since Tenshimakaibun is long and continuous in the vertical direction, it is possible to manufacture bundles of continuous ultrafine fibers, and the resulting fiber bundles also have multiple ultrafine fibers that are arranged independently and in parallel. A special structure is required for the Kerr spinneret, which results in a complicated and expensive device. Moreover, in all of these methods, ultrafine fiber bundles can only be obtained after a post-processing step is performed in which the sea fraction is extracted.

繊維束を得るに至ったものである。Against this background, the inventors of the present invention have conducted intensive research to develop a technology to produce ultrafine fiber bundles without requiring special secondary processing or post-processing processes, and as a result, they have found a technology that would be unimaginable with conventional common sense. By perfecting the new spinning technology, that is, the spinning technology in which the fiber itself spun from a single spinning hole is already a bundle of ultrafine fibers, the ultrafine fiber bundle of the present invention was obtained. It is.

A method is described (bottom left and right columns of page 2 of the publication). Here, fibrous gel is defined as "the O-fiber structure of fibrous polyolefin defining a network structure that interconnects capillary spaces filled with a reaction medium" (Page 3 of the publication). Upper left column, row 9 to 1

の目的は達成できない。Auxiliary agent> Auxiliary agent IL which is another precept of the present invention When a thermoplastic resin and water are mixed, water gradually disperses into the thermoplastic resin and causes a phase inversion, resulting in Its main function is to produce an aqueous dispersion in which the continuous phase is water, such as a thermoplastic resin dispersed in water. It is thought that the occurrence of such a phenomenon by melt-kneading causes the production of ultrafine fiber bundles in bulk. That is, by simply melt-kneading a thermoplastic resin and water without using an auxiliary agent, an ultrafine fiber bundle cannot be produced, and therefore the object of the present invention cannot be achieved.

It is thought that the water further penetrates into the interior, swells the auxiliary agent present inside, and promotes the division of the thermoplastic resin, ultimately giving an aqueous dispersion in which the thermoplastic resin is finely divided by water. .

ある。The features of this type of auxiliary agent are that the types of thermoplastic resins that can be used are fewer than those of the auxiliary agents described below, and that if the manufactured ultrafine fiber bundle is left alone, the ultrafine fibers will gradually break down over time. The result is a fiber bundle that looks like it is firmly adhered, and a fiber bundle that also has hydrophilic properties.

頁に開示されている。Among the above surfactants, if one converted into an anionic surfactant by addition treatment with a basic substance is used, the produced ultrafine fiber exhibits alkaline properties, that is, pH 9 or higher. In addition, nonionic surfactants result in ultrafine fiber bundles exhibiting properties of approximately neutral pH. In the case of nonionic surfactants, those with an HLB value of 13 to 19 are preferred because they produce ultrafine fibers with a smaller diameter. HLB value is Griffin

す。To explain in detail the meaning of (2) above, the water added to the system is gradually sucked into the molten resin by the shearing force caused by mixing and the action of the auxiliary agent, forming a W/O type dispersion. . If shearing force is continued to be applied, this time, even though the amount of water dispersed is small (at most 3 to 20 parts by weight per 100 parts by weight of the thermoplastic resin and auxiliary agent). Water becomes a continuous phase and the phase inverts to O/W type. This W/O to O
/W is on the verge of a phase change (incoming water does not form a completely continuous phase (water combined three-dimensionally), but continues in a certain direction (water combined two-dimensionally). Therefore, under the latter condition, the thermoplastic resin is considered to be not particles but a fibrous resin phase that is continuously connected in one direction.Under such conditions, spinning By doing so, the fiber bundle of the present invention can be spun, and even if the fiber bundle of the W/0 type or completely 07W type is spun, not only the ultrafine fiber bundle of the present invention cannot be produced, but it may not even become fibrous. Therefore, the term "just before phase inversion" as used herein refers to the range in which a fiber bundle such as that of the present invention can be spun.

した繊維束となって出てくることである。Regarding (2), the meaning of spinning by passing through an orifice is that the resin on the verge of phase inversion becomes fibrous with water as the boundary phase, but as it is, many of these fibrous resins are randomly oriented. Since it is a material that has a fibrous structure, it exhibits the effect of aligning the fibrous resin by applying orientation in a certain direction. This differs from the conventional melt spinning method (round). The fibers come out as a bundle of fibers that are bundled approximately parallel to the direction in which they are extruded.

れる繊維束の含水率は17重量%以下である。Regarding (2), when the molten blend is finally spun to the outside, the water contained in the molten mixture should not be substantially flannoshed, that is, the sudden extrusion that causes the water to flash as in the conventional flash spinning method should be stopped. It is. If the molten mixture is rapidly extruded as in the flash spinning method or extruded with a differential pressure applied, a fiber bundle cannot be obtained. More specifically, there is a method in which spinning is performed under pressure, or a method in which the pressure in a melt-kneading machine is made approximately the same as atmospheric pressure and spinning is performed under atmospheric pressure. The moisture content of the fiber bundle obtained by spinning under such conditions is 17% by weight or less.

しい。As a specific device for producing the ultrafine fiber bundle of the present invention, there is, for example, a method of extruding it using a single-screw or twin-screw extruder. In the case of a twin-screw extruder, the shearing force is too strong and it is difficult to reproduce a state on the verge of phase inversion, so it is better to weaken the shearing force by making the screw groove into a special shape. Generally, a single-screw extruder is preferred because it has a weak shearing force and can easily reproduce a state on the verge of phase inversion.

An ultrafine fiber bundle in which a large number of thermoplastic resin ultrafine fibers of 0μ or less are bundled in a substantially parallel state without being twisted, and the ultrafine fibers that make up the fiber bundle are partially adhered to each other. It means that a place exists. Therefore, when this fiber bundle is unraveled, it appears to be fibrous at first glance because of the adhesive parts.

はなく、また、実質的に毛羽立ちはない。The fact that the fibers constituting the fiber bundle of the present invention are substantially equivalent to single fibers formed singly means that each constituent fiber is The fibers have a shape that is substantially the same as if they had been formed individually (for example, by melt-spinning), and although the thickness of each fiber is not necessarily the same, there is no branching other than due to the adhesion of the fibers to each other. This means that there is substantially no separation, and the fiber bundle of the present invention is composed of these fibers assembled together. Therefore, the shape is different from physically splitting a melted or shaped belt-like or string-like molded product, and there is no cut surface on the surface of each fiber, and there is substantially no fuzz.
