One of the polymer blend component phases constitutes an island component, the other polymer blend component phase constitutes a sea component, and each of the polymer blend component phases constituting the island component constitutes a sea component. This invention relates to multi-component mixed spun fibers that are mixed in a dispersed state.

生産されている。 Polymer blends In particular, mixed spun fibers made of two-component polymer blends have a sea-island structure in which one component is finely dispersed in the other, so if one component (generally the sea component) is removed after fiber formation, the island component can be removed. Ultrafine fibers made of polymer can be obtained. And the sea-island structure of mixed spun fibers from polymer blends ranges from several hundred to several hundred per fiber cross section.
Since it has several thousand islands, the fineness of the resulting fiber made of island components (usually called island denier) is
It is about 0.01 to 0.0005 dr, which is 2 to 4 orders of magnitude smaller than normal fibers, which is why it is called ultra-fine fiber. Further, this ultra-fine fiber has extremely high utility value industrially, and for example, ultra-fine fiber made of polyamide is industrially produced as material fiber for suede-like artificial leather.

付与されるであろう。 In general, polyamide and polyester each have excellent characteristics and are widely used as fibers for various purposes. Polyamide has excellent strength, dyeability, and moisture absorption, but it also has poor washing fastness, Young's modulus, It has the disadvantage of low heat resistance,
On the other hand, polyester has Young's modulus, initial modulus,
They have seemingly contradictory drawbacks, such as excellent heat resistance and heat setting properties, but poor dyeability and moisture absorption, and each cannot necessarily be said to be a panacea.
However, it is clear that if these could be complemented, their utility value would be greatly improved.
In particular, if there is an ultra-fine fiber like the one mentioned above that has both the characteristics of polyamide and polyester,
It is thought that this will not only improve the washing fastness of dyed products, but also significantly improve the poor shape stability when wet, which is a drawback of using polyamide alone as a suede-like artificial leather material fiber. On the other hand, as a base fiber for high-grade silver-plated artificial leather, it is thought that it will be softer, lighter, and more comfortable to wear. Furthermore, the same fiber can be used for both suede-like artificial leather and silver-finished artificial leather, which is an effective feature not found in conventional ultrafine fibers.

る。 That is, the present invention provides a mixed spun fiber comprising at least two types of polymer blends, in which a polymer blend component phase A is used as a fiber-forming polyamide (hereinafter sometimes simply referred to as polyamide) island phase.
and a polymer blend component phase B having fiber-forming polyester (hereinafter sometimes simply referred to as polyester) as an island phase, one of which is an island component with 10 or more fibers, and the other polymer The blend component phase is a sea component, and each of the polymer blend component phases constituting the island component is mixed in a dispersed state in the polymer blend component phase constituting the sea component in a multicomponent mixed spun fiber.

なる超極細繊維とはならない。 Conventionally, mixed spun fibers obtained by mixing and spinning a polymer blend composition of polyamide and polyester have been disclosed in Japanese Patent Publications No. 46-34908, No. 46-34909, and No. 47-Sho.
18888, Belgian Patent No. 661784, etc., and are publicly known. However, these mixed spun fibers made of polyamide and polyester form a sea-island structure in which either polyamide or polyester forms a sea phase or an island phase, so the resulting mixed spun fiber itself is composed of both polymers. Although it may be possible for the polyamide component and the polyester component to exist simultaneously forming a uniform island phase. Therefore, even if the sea component is removed, ultrafine fibers made of both polyamide and polyester cannot be obtained.

ーの異なるものである。 On the other hand, with recent advances in composite spinning technology, various composite spun fibers have been developed by utilizing multicore-to-sheath spinning methods, exfoliation type composite spinning methods, and petal-shaped cross-section fiber spinning methods. For example, from peelable fibers or petal-shaped cross-section fibers containing polyamide and polyester as composite components, ultrafine fibers in which both components coexist can be obtained by separating the components using an appropriate method. In addition, even in the case of multicore-to-sheath spun fibers, if the core component is made of two components, polyamide and polyester, and the sheath component is removed by an appropriate method, an ultrafine fiber consisting of polyamide and polyester can be obtained. However, the number of units that can be made ultra-fine in fibers obtained by composite spinning is usually limited to several tens per single composite spun fiber, whether it is a peel type or petal-shaped cross section or a multicore core-sheath type. . Therefore, the fineness of the ultra-fine fibers after being ultra-fine is approximately 0.1 to 0.03 dr, which is on the order of 0.01 to 0.0005 dr of the ultra-fine fibers obtained starting from mixed spun fibers made of polymer blends. They are different.

とした極細繊維において、前者は長さ方向に完全

つという違いがある。 In general, in ultrafine fibers made from mixed spun fibers made of polymer blends and ultrafine fibers made from composite spun fibers, the former are not completely continuous in the length direction, but are partially interconnected. The difference is that while the latter is said to have a straight structure that is completely continuous in the length direction.

せてしまう。 The difference between these two points is that when these fibers are used as material fibers for artificial leather, the first difference is the fineness, which is a decisive factor in surface creation when used for the base fabric of silvered artificial leather. This appears as superiority or inferiority, and the difference in straightness in the fiber length direction appears as a difference in the shedding of fluff (shedding) of napped artificial leather. In other words, the artificial leather base fabric made from ultrafine fibers obtained from a polymer blend of 0.01 to 0.0005 dr may be due to the extremely small fineness of the constituent fibers, but even mechanical deformation, especially tension, can cause the surface of the base fabric to It has the excellent feature that it does not cause large irregularities on the surface, so even after the silver surfaces are bonded together, there is almost no disturbance of the silver surfaces called "moro". However, when using ultra-fine fibers with a thicker fineness than this,
Mechanical deformation, especially tension, tends to cause unevenness to appear on the surface of the base fabric, and when the silver surfaces are bonded together, this appears as a lump and significantly reduces its commercial value.

硬くペーパーライクなものになつてしまつた。 On the other hand, according to the inventors' study regarding the shedding of fuzz (hair loss) in suede-like artificial leather,
When using ultra-fine fibers made of polymer blends, the conditions are not such that the binder completely adheres to the ultra-fine fibers, but rather the conditions are such that the ultra-fine fibers are relatively gently surrounded by the binder and partially adhere to each other. Even under such conditions, the shedding of fuzz can be sufficiently prevented, probably because the ultra-fine fibers have a network structure. However, when ultrafine fibers made from composite spun fibers are used, unless the conditions are such that the binder and the ultrafine fibers are firmly bonded, the fuzz will be prevented from falling off, probably because the ultrafine fibers are striated in the length direction. That was extremely difficult. Moreover, the nonwoven fabric made by strongly adhering the ultrafine fibers and the binder has a very hard and paper-like texture.
以上のように、ポリマーブレンドからなる混合
紡糸繊維を出発とした超極細繊維は、複合紡糸繊
維を出発とする極細繊維に比して人工皮革用素材
繊維として優れているということができる。 As described above, it can be said that ultrafine fibers made from mixed spun fibers made of polymer blends are superior to ultrafine fibers made from composite spun fibers as material fibers for artificial leather.

On the other hand, part 2 is a polymer blend component phase having polyamide as an island phase, and part 4 is an enlarged view thereof. In this example, within the cross section of one multicomponent mixed spun fiber, 12 parts 2, that is, parts that have polyamide as an island phase, are uniformly dispersed within part 1, that is, a polymer blend component phase that has polyester as an island phase. It is something that Of course, in actual fibers, there is no boundary line between portions 1 and 2 as shown in FIG. 1, and this is shown for convenience of explanation. Therefore, in the multicomponent ultrafine fiber obtained after removing the sea phase from the multicomponent mixed spun fiber of the present invention exemplified herein, a portion consisting of the ultrafine fiber of the polyamide component and an ultrafine fiber of the polyester component are separated. A state is realized in which the parts consisting of fibers are uniformly mixed and dispersed in minute units. As a result, the aggregate of ultra-fine fibers exhibits the characteristics of polyamide and polyester in a well-balanced and complementary manner.

の欠点が相乗的に発現する場合すらある。 However, for example, mixed spun fibers made of a polymer blend containing polyamide as an island component and mixed spun fibers made of a polymer blend containing polyester as an island component are spun and then combined and drawn, or they are stapled and then blended. Therefore, in a product in which polyamide and polyester are mixed and dispersed, the mixing unit of both is much larger than in the case of the present invention, and although it can be called an ultrafine fiber made of polyamide and polyester, it is difficult to use it as a material fiber for artificial leather. In actual applications, the characteristics of polyamide and polyester are not expressed in a well-balanced and complementary manner, but rather the disadvantages of both may be expressed synergistically.

In exactly the same way, the chip blend polymer in which polyester is an island component is melted, mixed, and extruded into the hopper of the other extruder type extruder, and introduced into the sheath or core component supply hole of the multi-core-to-sheath composite spinning nozzle to form a multi-core to sheath composite. All you have to do is spin it. In this case, the number of cores in the multicore sheath is 10 or more. This core is formed of a polymer blend component with islands of polyamide or polyester, and it is clear that the greater the number of cores, the higher the degree of dispersion mixing of the two polymer blend component phases. After removal, the polyamide and polyester ultra-fine fibers exhibit their complementary characteristics without any discomfort at all, especially when there are 10 or more fibers.

らなかつた。 However, the multi-component mixed spun fiber of the present invention can be obtained by chip-blending a three-component polymer consisting of polyamide and polyester as the island component and other polymers as the sea component and melt-extrusion spinning the polymer blend. It is not possible.
That is, in the mixed spun fiber obtained in this case, the sea-island structure is such that polyester islands and polyamide islands coexist in the sea phase consisting of the third component polymer, but only one polyamide island is realized. Each fiber or each island of polyester is a unit of dispersion mixing, and as in the multi-component mixed spun fiber of the present invention, a polymer blend component phase having polyamide as an island phase and a polyester as an island phase are used. The polymer blend component phase serves as a unit of mixing and dispersion (see Figure 1).
It is clearly different from that. This is schematically shown in Figure 2, and 5 is an enlarged view of it (white dots indicate polyamide islands, black dots indicate polyester islands). Figures 1 and 2 clearly show how the fibers of the present invention and conventional fibers are mixed, and at first glance it would not seem that there is a big difference between the two, but the inventors' detailed study According to
Even if a multi-component mixed spun fiber having a structure as shown in Fig. 2 is used as a fiber for artificial leather, it will not be possible to use the multi-component mixed spun fiber of the present invention as shown in Fig. It was found that it was impossible to create a material that had both the characteristics of ultrafine fibers. In other words, in the case of multi-component mixed spun fibers as shown in Figure 2, the artificial leather using ultra-fine fibers obtained after removing the sea component is as follows:
Ultra-fine fibers made only of polyamide, of course, have a much harder texture than those made using ultra-fine fibers made only of polyester, and it is as if the ultra-fine fibers were not made ultra-fine by removing the sea component at all. However, in the case of napped artificial leather, even if you try to make it fluff by buffing, etc., the fluff ends are hardly opened, resulting in a poor appearance and feel that cannot be compared to completely natural napped leather. I had no choice but to do so.

減少等により生産性も向上した。 As described above, the multi-component mixed spun fiber of the present invention has a polymer blend component phase having polyamide as an island phase and a polymer blend component phase having polyester as an island phase, one of which is a polymer blend component phase of the other. Since they are currently in a dispersed state in the polymer blend component phase, by removing the sea component in both polymer blend component phases, multiple bundles of ultrafine fibers made of polyamide are dispersed in the ultrafine fibers made of polyester. Or, conversely, an aggregate of ultra-fine fibers is obtained, in which multiple bundles of ultra-fine fibers made of polyester are dispersed and mixed in ultra-fine fibers made of polyamide, and this is used as a fiber component to create artificial leather with a raised texture. When manufactured, the characteristics of polyamide ultra-fine fibers and polyester ultra-fine fibers complement each other in a well-balanced manner, and the resulting artificial leather is more resistant to dyeing than when polyamide ultra-fine fibers are used alone. The temperature and morphological stability during wet conditions were significantly improved. In addition, when artificial leather for shoe uppers was manufactured using the same ultra-fine fibers as a fiber component, it was found to be more flexible and lighter than that made using only polyester ultra-fine fibers, and was more comfortable to the touch when worn. Summer. Furthermore, in actual production, the same fiber can be used for both the raised artificial leather and the artificial leather for the upper leather, which improves productivity by increasing the operating rate of equipment and reducing various losses during fiber manufacturing.

の延伸糸を得た。Example 1 Nylon 6 with a relative viscosity of 2.7 and high-pressure polyethylene with a melt index of 50 were mixed in the form of chips at a weight ratio of 1:1 to form a so-called chip blend.
The extruder of the stand was fed into one popper of a multi-core sheath spinning machine connected in a composite type. Then, the mixture was melted, mixed, and extruded in an extruder, measured using a gear pump, and introduced into a core component introduction hole of a multicore-to-sheath spinning mechanism. As a result, the polymer blend containing nylon 6 as an island component flows into the core component introduction hole. In addition, polyethylene phthalate with an intrinsic viscosity of 0.68 and high-pressure polyethylene with a melt index of 50 are chip-blended at a weight ratio of 1:1 and supplied to the hopper of the other extruder, melted, mixed and extruded in the same manner, and further pumped into a gear pump. After weighing, it was guided to the sheath component introduction hole of the multi-core sheath spinning mechanism. As a result, the polymer blend containing polyethylene terephthalate as the island component flows into the sheath component introduction hole. In this case, the metering ratio in the gear pump was set to 1:1 by weight. In addition, the number of cores in the multi-core core-to-sheath spinning mechanism is 1.
A total of 12 filaments were used per filament. Next, the polymer stream passed through a multi-core-to-sheath spinning mechanism, was discharged from a spinneret, and was wound up into a single 12-denier undrawn yarn. This undrawn yarn was subjected to two-stage stretching at a magnification of 3.0 times in a hot water bath at a temperature of 75° C. for the first bath and 98° C. for the second bath to obtain a drawn yarn of the multicomponent mixed spun fiber of the present invention having a single yarn of 4 deniers.

As shown in the figure, a sea-island structure, in which a polymer blend component phase with polyamide as an island phase and polyethylene as a sea phase, is inserted into a polymer blend component phase with polyester as an island phase and polyethylene as a sea phase, as if they were 12 cores. It was found that the mixture was evenly dispersed and mixed. When the fineness of the island phase of polyamide and polyester was actually measured, the average fineness was about 0.003 dr for polyamide and about 0.0015 dr for polyester. The obtained multi-component mixed spun fiber was mechanically crimped and cut into a length of about 51 mm, which was then passed through a random web to form a web. The webs were stacked to a basis weight of 400 g/cm 2 , needle-punched, heat-set, wet-coagulated with polyurethane impregnation, and further treated in hot toluene to extract and remove the sea component of polyethylene.

However, in this case, a polymer blend with polyester as an island component and polyethylene as a sea component flows into the core component introduction hole, and a polymer blend with polyamide as an island component and polyethylene as a sea component flows into the sheath component introduction hole. The conditions were the same as in Example 1. Furthermore, water bath two-stage drawing was carried out in the same manner as in Example 1 to obtain a drawn yarn of a multi-component mixed spun fiber of 4 dr single filaments.

It was as if ultra-fine refinement by removing sea components had not been performed. Furthermore, the suede-like artificial leather had poor fluffing during buffing treatment, and the fluff tips were hardly opened, making it a product with no commercial value as suede.
