More specifically, the introduction of the third component, the combination with other fibers, the change in the cross-sectional shape, and the like can provide an ultraviolet shielding effect, a cationic dyeability, a flame retardancy, a faux yarn type, a high volume feeling, and a surface. An antistatic polyester microfiber having various functions such as soft touch and toughness, backlash, dryness, natural feeling, 0 spunized appearance, felt touch, shrinkage recovery, water absorption, quick drying property, and a method for producing the same. [Prior Art] Since the past, attempts have been made to impart hydrophilicity to polyesters to exhibit antistatic properties. For example, a method of adding a polyoxyalkylene-based polyether compound to a polyester (Japanese Patent Publication No. Sho 39-5214), and substantially adding an incompatible polyoxyalkylene polyether compound and an organic/inorganic ion Q compound to the polyester are known. (Japanese Unexamined Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. 94 1 3, and JP-A-3-139556, etc.). Among these methods, if the single yarn fineness is larger than 1.6 dtex, the antistatic property is obtained, but in the ultrafine yarn, the dispersion of the core/sheath is formed and the dispersion of the single yarn fineness is such that no antistatic property is present. However, in recent years, there has been an increasing demand for the handling of the woven fabric, the touch of the skin, and the appearance. The fabric woven by the ultrafine polyester stretch yarn of the past has a soft touch and improves the heat retention. -5- 201040334 Properties such as water absorption and hygroscopicity, but there is almost no antistatic fabric that can suppress static electricity. In particular, it is used for the purpose of shielding the ultraviolet rays from the outdoor clothing, and it is used for the purpose of suppressing static electricity. 'The cloth with antistatic properties cannot be obtained as the current situation. 'The polyester is not good for dyeing when used as the fiber for clothing, and has the sharpness of dyeing. The disadvantage of deterioration. In the past, in order to compensate for such a disadvantage, a polyester having a sulfonic acid base represented by 5-sodium sulfoisophthalic acid or the like as a dyeable polyester (hereinafter referred to as a cationic dyeable polyester) is copolymerized. It is well known that fibers made from such polyesters are used in the field of clothing. However, these cationic dyeable polyester fibers have a higher melt viscosity than ordinary polyester fibers, and it is difficult to reduce the melting during combustion, so that there is a problem that the defects are easily prolonged and the use in the field requiring flame retardancy is limited. In order to solve such a problem, a polyester containing a sulfonic acid base component to copolymerize a specific phosphorus-containing dicarboxylic acid compound is disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. A polyester copolymerized with an organophosphorus compound. However, in this method, by the acid catalyst action of the phosphorus compound, the formation of diethylene glycol is promoted during the polymerization reaction, and the problem of deterioration of the bleeding property and the light resistance is improved by increasing the content of the diethylene glycol. . In addition, the polyester fiber 'especially for the polyester long fiber' is a method of imparting a tactile-like feel or high volume property such as high-grade wool, for example, Japanese Patent Publication No. Sho 60-11130, Japanese Patent Publication No. Sho 61-19733, The high volume is improved by combining the imitation yarn type 様捻 2 -6 - 201040334 layer structure yarn having the long vinegar long fibers having two or more kinds of elongation differences as shown in JP-A-8-13275 and JP-A-2006-169697. Or the self-extending polyester multifilament yarn and the heat-shrinkable polyester fiber yarn are mixed in an air nozzle or by a relaxation heat treatment, and the polyester is automatically extended. The fiber yarn is subjected to a slow heat treatment, and the heat-shrinkable polyester fiber yarn is continuously supplied to the self-expanding polyester fiber yarn after the relaxation heat treatment, and the air fiber nozzle is used for mixing the fiber (for example, JP-A-25025) No. bulletin) was proposed. 0 However, in the general extended yarn (FOY), even if it has antistatic property, when the false twisting process or the air blending as described above is performed, it is easy to cause the batt by the deformation or friction of the kneading yarn, so that sufficient antistatic property cannot be imparted. For the truth. [PRIOR ART DOCUMENT] [Patent Document 1] Japanese Patent Publication No. Sho. No. Sho.

R20-(CH2CH20)n(R10)m-R2 (1) [wherein, an alkyl group having 2 or more carbon atoms or a substituted alkyl group, and R2 is a hydrogen atom a monovalent hydrocarbon group having 1 to 40 carbon atoms, a monovalent hydroxy hydrocarbon having 2 to 40 carbon atoms or a monovalent fluorenyl group having 2 to 40 carbon atoms, and η is an integer of 1 or more, and m is 1 or more. Specific examples of the polyoxyalkylene-based polyether include polyoxyethylene glycol having a molecular weight of 4,000 or more, polyoxypropylene glycol having a molecular weight of 1,000 or more, polyoxytetramethylene glycol, and a molecular weight of 200 00. The above ethylene oxide, propylene oxide copolymer, trimethylolpropane ethylene oxide adduct having a molecular weight of 4000 or more, nonylphenol ethylene oxide adduct having a molecular weight of 3,000 or more, and these terminal OH a compound having a carbon number of 6 or more substituted ethylene oxide added thereto, wherein both ends of polyoxyethylene glycol having a molecular weight of 1,000,000 to 100,000 and polyoxyethylene glycol having a molecular weight of 5000 to 16,000 are also added. A compound in which an alkyl group having an alkyl group of 8 to 40 is substituted for ethylene oxide is preferred. The amount of the polyoxyalkylene-based polyether compound to be added is in the range of 0.2 to 30 parts by weight based on 100 parts by weight of the above aromatic polyester. When the amount is less than 0.2% -18-201040334, the hydrophilicity will be insufficient to exhibit sufficient antistatic property. On the other hand, when the amount is more than 30 parts by weight, the effect of improving the initial antistatic property cannot be obtained, and the mechanical properties of the obtained composition are impaired, and the polyether becomes easily leaked, so that the sheet is formed during the melt molding. The fusion property of the kneader for the kneader is lowered, and the form stability is also deteriorated. In the present invention, an organic ionic compound is added in order to particularly improve the antistatic property of the polyester A. The organic ionic compound is preferably a sulfonic acid metal salt represented by the following general formula (II) or (ΠΙ) and a sulfonic acid fourth-grade scaly salt.

In the above formula (II), when R is an alkyl group, the alkyl group may be slightly linear or may have a branched side chain. The hydrazine is an alkali metal such as Na, K or Li or an alkaline earth such as Mg or Ca. The metal is preferably used in the form of U, Na or K. The metal sulfonate may be used singly or in combination of two or more. Preferred examples are -19-201040334 sodium stearyl sulfonate, octyl Sodium sulfonate, sodium dodecyl sulfonate, sodium alkylsulfonate mixture having an average of 14 carbon atoms, sodium dodecylbenzenesulfonate mixture, sodium dodecylbenzenesulfonate (hard type) , soft type), lithium dodecylbenzenesulfonate (hard, soft) 'magnesium dodecylbenzenesulfonate (hard, soft), etc. Further, the sulfonic acid in the formula (III) is 4 Grade scale salt can be used alone or in combination 2 The above is used. As a preferred embodiment, tetrabutylsulfonium alkylsulfonate having an average number of 14 carbon atoms, tetraphenylphosphonium alkylsulfonate having an average number of carbon atoms of 14, and an average number of carbon atoms are used.

The polyester is preferably in the range of 0.05 to 10 parts by weight based on 1 part by weight of the polyester. When the amount is less than 5 parts by weight, the effect of improving the antistatic property is small, and when it exceeds 1 part by weight, the composition of the machine The properties are impaired, and the ionic compound is liable to leak, so that the fusion property of the sheet-like material at the time of melt molding to the kneader is lowered, and the molding stability is also deteriorated. In the present invention, various functions are imparted to the fiber. Therefore, the polyester B of the sheath portion is used as a copolymerized polyester. Among them, the copolymerization system The third component is introduced into the polymer skeleton by a general polymerization reaction, and after the polymer is blended, it reacts with the terminal group to enter the polymer skeleton, and also contains a polymerization form called a chain extension, or The redistribution reaction proceeds to the polymerization form of the polymer skeleton of -20-201040334. First, in the present invention, in order to improve the weather resistance, the polyester I is 0.1 to 5.0% by weight based on the total weight of the polyester (preferably ο) . . % of the organic UV absorber, and copolymerization is better than the content of the UV absorber of the good machine is less than 0.1% by weight, not sufficient UV absorption performance is not good. Conversely, the organic UV agent When the content is more than 5.0% by weight, when the polyester containing the organic ultraviolet agent is spun to obtain a polyester fiber, the step of spinning is impaired, and the color sharpness is also lowered, which is not preferable. Examples of the organic ultraviolet absorber include a benzoxazine-based external absorbent, a benzophenone-based organic ultraviolet absorber, a benzoic organic ultraviolet absorber, and a salicylic acid-based organic ultraviolet absorber. From the viewpoint that the central portion will be decomposed, it is particularly preferable to use a benzoxazine ultraviolet absorber. Although the reason why the benzoxazine-based organic ultraviolet ray is excellent is not clarified, it has high heat resistance as compared with other ultraviolet ray absorbing agents, and the polyamidity is preferred as the cyclic imine ester. Less leakage. The benzoxazine-based organic ultraviolet absorber is preferably those disclosed in the publication No. 62-1741. That is, 2; tolyloxazin-4-one, 2-butyl-3,1-benzoxazin-4-one, 2-benzobenzoxazine-4-one, 2,2' -Extended ethyl bis(3,1-benzoxazine-4-2,2'-tetramethyl-bis(3,1-benzoxazin-4-one), 2,2'-ρ-stretch (3,1-benzoxazin-4-one), 1,3,5-tris(3,1-benzoxazinyl)benzene, 1,3,5-tris(3,1-benzo) Izine, such as oxazin-4-one-2-yl)naphthalene, contains 丨~3·〇. If there is a method to obtain linear absorption line, the absorption is qualitative and the organic purple triazole system. Among them, the organic absorbent ratio, the ester-pro Further, the opening of the antistatic core-sheath type polyester ultrafine fiber of the present invention is formed in the poly-based medium of the anti-static core-sheath type polyester ultrafine fiber of the present invention. It is preferred to contain 0.5% by weight or less of an inorganic ultraviolet absorbing and/or reflecting agent. The content of the inorganic ultraviolet absorbing and/or reflecting agent is 〇. 5 by weight. /. When it is big, it not only damages the sharpness, but also damages the weaving property. Further, examples of the inorganic ultraviolet absorbing and/or reflecting agent include inorganic compounds such as titanium oxide, zinc oxide, aluminum oxide, magnesium oxide, talc, kaolin, calcium carbonate, and sodium carbonate. Further, in the polyester which forms the antistatic core-sheath type polyester ultrafine fiber of the present invention, in addition to the organic ultraviolet absorber, a fine pore former and a cation may be added as needed within a range not impairing the object of the present invention. One or more of a dyeable agent, a coloring preventive agent, a heat stabilizer, a flame retardant, a fluorescent whitening agent, a coloring agent, a charge preventing agent, a moisture absorbent, an antibacterial agent, and an anion generating agent. Further, the area ratio in the cross section perpendicular to the fiber axis of the core polyester A and the sheath copolymerized polyester B must be in the range of 5: 95 to 80: 20. If the area ratio is 5: 9.5 hours, the antistatic performance of polyester A will be insufficient. 'When 80: 20 is larger, the antistatic aggregation of the core is applied when the alkali reduction is 10% or more. When the ester is dissolved, the antistatic property is lowered, and the strength of the stretched yarn is also lowered, which is 3 0 c c / dte X or less. When the fabric is insufficient, the strength is insufficient, so it is not suitable for the strength of the suiting material. On, the use is limited. The antistatic core-sheath type polyester ultrafine fiber of the present invention uses the above-mentioned copolymerized polyester B on the sheath side using the conventionally known composite spinning device, and the polyester A in the core-22-201040334, 2000 to 3 It is important to carry out melt spinning at a speed of 00 0 m/min, and it is important to carry out the suction in the range of the discharge speed and the suction speed at the time of spinning (hereinafter referred to as the slope ratio) of 10 0 to 800. As the heat treatment method, any yarn forming conditions such as melt spinning at the above-described speed and simultaneous or continuous stretching may be employed. Further, the obtained antistatic core-sheath type polyester ultrafine fiber is continuously spun, and the so-called DTY processing is preferably performed, or after the stretching, the wound may be subjected to false twist processing. In the present invention, when the yarn or the woven fabric produced by the fiber is heat-treated at a temperature of 100 ton or more, the structure can be stabilized and the polyethylene oxide-based polyether contained in the fiber can be promoted, and if necessary It is preferred that the alignment of the migration of various additives is improved. Further, if necessary, it is possible to use a combination of heat treatment such as relaxation. Further, it is preferable that the antistatic core-sheath type polyester ultrafine fiber of the present invention or the woven fabric produced from the fiber can be subjected to a suitable hydrophilization and then processed. As the post-hydrophilization process, for example, a polyester polyether chiral copolymer composed of terephthalic acid and/or isophthalic acid or a lower alkyl ester thereof, a lower alkanediol, and a polyalkylene glycol A method of treating an aqueous dispersion or a grafting polymerization of a hydrophilic monomer such as acrylic acid or methacrylic acid is preferred. Further, in the present invention, in order to improve the dyeability, it is preferred that the polyester B has a sulfonic acid alkali-containing acid component of 1.0 to 5.0 mol% based on the total acid component. When the amount of copolymerization of the acid component containing a sulfonic acid base is less than 0.5 mol%, 'sufficient dyeing performance cannot be obtained, and the cationic dye cannot be dyeable. When the amount of the cationic dye is more than 5.0 mol%, the melt viscosity of the polyester resin will be It is not good to improve the spinning workability or the yarn strength. The sulfonic acid base is not particularly limited as long as the acid component is a sulfonic acid alkali-containing component having a functional group reactive with the polyester, and examples thereof include 5-sodium sulfoisophthalic acid and 5- Potassium sulfoisophthalic acid, 5-lithium sulfoisophthalic acid, sodium sulfonaphthalene dicarboxylic acid, 5-sodium sulfophthalic acid, and the like. Among them, in particular, 5-sodium sulfoisophthalic acid is preferred because it is excellent in color developability and spinnability by a cationic dye. Further, in the polyester B constituting the fiber of the present invention, the content of the organophosphorus compound represented by the following general formula (2) as a flame retardant is a phosphorus atom content of 1,000 to 1 for the total weight of the polyester. 0,000 ppm, preferably 3,000 to 9,000 卩卩 111, which is particularly good for copolymerization of $.

Next, the embodiment of the second invention of the present invention will be described in detail. According to a second aspect of the present invention, a polyester composite false twisted textured yarn is obtained by forming two types of polyester filaments having different elongations in a longitudinal direction to form a bundle portion of an alternate crepe-like take-up portion and an entangle portion. And the fiber opening portion' is characterized by satisfying the following requirements (i) to (W). (i) It is a core-sheath type polyester composite fiber composed of a polyester filament X having a small degree of elongation, a polyester portion 0A from a core portion, and a copolymerized polyester B at a sheath portion, wherein the polyester A is composed of 100 parts by weight of the aromatic polyester, containing 0.2 to 30 parts by weight of the antistatic agent, (a) a polyoxyalkylene-based polyether represented by the following general formula (1), and 0.05 to 10 parts by weight (b) And the polyester is made of an antistatic polyester which is a substantially non-reactive organic ionic compound.

O ( iii ) The polyester filament X is a core portion constituting the composite false twisted yarn, and the polyester filament Y is a two-layer structure in which the core portion is wound around the core portion to form an outer layer portion (sheath portion). (iv) The average yarn length of the polyester filament Y is 5 to 20% longer than the average yarn length of the polyester filament X; R2O-(CH2CH20)n(R10)m-R2 (1) [wherein R1 is An alkyl group having at least 2 carbon atoms or a substituted alkyl group, -25- 40 201040334 R2 is a hydrogen atom, a monovalent hydrocarbon group having 1 to 40 carbon atoms, a monovalent hydrocarbon having 2 to 2 carbon atoms or a carbon atom A monovalent fluorenyl group of 2 to 40, η is an integer of 1 and m is an integer of 1 or more]. The polyester filament X having a small core elongation of the antistatic polyester composite false twist processing yarn of the present invention is a core sheath composed of a polyester A and a copolymerized polyester B. In the polyester-based composite fiber, the polyesters and B used in the core-sheath type composite fibers of the first invention of the present invention are the same polyester. Secondly, the polyester filament Y having a large elongation of the antistatic polyester composite false twisted textured yarn of the present invention is a methyl terephthalate or a tetramethylidene group. The polyester fibril having terephthalic acid as the main heavy unit is mainly used, but if necessary, the third fraction may be a small amount (generally, Hmol% or less, preferably 10 mol% or less, based on the total repeating unit). Preferably, the copolymerization of the polyester is carried out at a concentration of 5 mol% or less, and a matting agent or other additives may be added. Among them, when the microporous forming agent for forming micropores or fine grooves is formed on the surface of the fiber or inside the fiber by the alkali reduction treatment, the shape of the pore or the shape can exhibit water absorption, natural feel, and vividness. It is better to have various effects such as dryness. As a method for obtaining the antistatic polyester composite false twisted textured yarn of the present invention, the undrawn yarns of the polyester filament X and the polyester filament Y are entangled and twisted, and the untwisted yarn is untwisted and becomes an interaction. Obtained from the yarn. As a combination of two or more types of polyester filaments in the present invention, a groove having a small elongation can be used to form a groove of a sphing ester A which is stretched to a yarn of at least 1-2 times or more. When the square is stretched, the -26-201040334 is used, and the sliver having a larger elongation is preferably used to extend the yarn to 40% or more than the sliver having a smaller elongation. Further, the elongation of the polyester filament X having a small elongation is 50% or more, preferably 60% or more, and the elongation of the polyester filament Y having a large elongation is 1% or more. Preferably, the difference in elongation between the low elongation polyester filament X and the high elongation polyester filament Y is 20% or more, preferably 40% or more, more preferably 50% or more. Very good for 50~70%. 0 Among them, if the difference in elongation is less than 20%, the high volume of the false twisted textured yarn cannot be obtained. In the case where the elongation of the polyester filament X or the polyester filament Y is adjusted, a known method can be used to adjust the stretching ratio and the like. Further, the ratio of the polyester filament X to the polyester filament Y may be appropriately selected depending on the purpose, but it is preferably 20% or more, and the ratio of the two is polyester yarn: X: polyester filament Y = 25 : 75 to 75 : 25 (weight) is preferred. In particular, it is preferable that the ratio of the polyester fibril with a large degree of elongation is large, and when it is expressed by the ratio of (polyester filament X) / (polyester fibril), it is G 30/70 to 45/55. The scope is appropriate. By the constitution as described above, the polyester filament enthalpy can be preferentially extended in the composite false twisting step, so that the polyester filament X is less damaged, the yarn breakage and the batt are less generated, and even the polyester fiber The silk X produces fluff, which can be covered by the polyester fibril so that the problems caused in the subsequent fabricating step can be alleviated. Further, in the range which does not impair the object of the present invention, other fibers, for example, metal-plated fibers or fibers mixed with carbon particles, may be combined to impart conductivity. However, when other fibers are used in combination, the ratio is not 30% of the total. In the following -27-201040334, the tendency to reduce the high volume is not good. In the present invention, it is preferred that two or more types of undrawn yarns having different elongations are drawn, and the air entanglement processor is applied by a nozzle of air injection before stretching. As the method of spraying the air, any method such as a method of walking in a direction perpendicular to the yarn or a direction of traveling along the yarn can be employed, and the former can obtain a product having a relatively good gloss, and the latter can obtain a relatively soft touch. (handling) products, so you can make appropriate choices according to the purpose. However, in the entanglement treatment, when the feed rate is excessively large, a large number of circuits are generated, and the stability of the step at the time of fabric production is impaired, so that it is preferably 10% or less. Further, an excessive feed rate difference can be set between undrawn yarns having different elongations. In this case, if the difference is too large, a large number of circuits are generated, so that the same excessive feed rate is employed. The false twist device can be applied to any one of a spindle that is wound on a twisted needle, a fluid air false twist nozzle, an internal or external friction false twist device, and a conveyor wipe device. When the embodiment is described with reference to Fig. 1, the two yarns 3, 3' having different elongations are fed to the guide device 4, and then supplied to the air for entanglement by the tension adjusting device 5 and the feed roller 6'. The nozzle 7 is here an entangled yarn having an intersection of 13 points/m or more. Then, the entangled yarn is supplied to the extended false twisting zone by the first transport roller 8, and is taken up by the second transport roller 11 via the heater 9 and the false cooker 10, and then taken up as the package yarn 13. After the entanglement is given, while the excessive feeding is performed, the heat treatment is performed on the heating -28-201040334, the polyester filament γ is shrunk, the polyester filament enthalpy is almost no shrinkage, or the self-extends, the polyester filament X and A yarn difference is generated between the polyester filaments γ. This is related to the expansion and the yarn-like type when the fabric is used. The use of the antistatic polyester composite false twist textured yarn of the present invention will be described. Figure 2 is a side elevational view of the false twisted textured yarn of the present invention. In Fig. 2, Ϊ denotes an interactive crepe-like take-up portion, II denotes an entangled portion 'III denotes a fiber-opening portion 〇〇, and an antistatic polyester composite false twisted textured yarn of the present invention is interactive in the longitudinal direction as shown in Fig. 2 It is important to form the bridging portion (X) formed by the interactive crepe-like winding portion (I) and the entangle portion (II) in interaction with the fiber opening portion (III). In the bundle portion (X) of the present invention, the interactive crepe-like take-up portion (I) is a core portion mainly composed of polyester filaments X, and an outer layer portion mainly composed of polystyrene filaments. The portion that is substantially wound up in a bundled state. Further, the entangled portion (II) is a portion in which the polyester filaments X and the polyester fibrils are closely intertwined in a state of mixing, and in the present invention, (I) and (π) are collectively referred to as a bundle portion. X). In such a bundled portion (X), since the entangled portion (II) aggregates the entire sliver, the secondary moment of the cross section is large, and the resulting fabric can impart high backlash. On the other hand, the interactive crepe-like take-up portion (I) is a portion that is more swollen than the entangled portion (11), and exhibits elasticity for extrusion, and imparts tension and toughness to the fabric (hand 1 ing) ). On the other hand, the fiber opening portion (III) -29 to 201040334 adjacent to the bundle portion (X) mainly consists of a core portion composed of the polyester yarn A, and the main polyester yarn B is separated from each other to be continuously inverted. The portion covered with the yarn axis in a state of being slightly parallel, the cloth bundle can be provided with a low-volume type of high-volume property and flexibility. The single fiber fineness of the appearance of the antistatic polyester composite false twisted textured yarn of the present invention (the average fineness when the thickness is uneven in the longitudinal direction) or the total fineness of the sliver is not particularly limited, and the single fiber fineness is 1.5. The range of ~5.0dtex is preferred, and the total fineness is suitably in the range of 30 to 30,000 dtex. The fineness of the unstretched yarn and the partially oriented yarn can be selected according to the application. Generally, in the full fineness, the 2 yarns of the yarn are preferred, the former being 30 to 400 dtex, and the latter being 20 to 150 dtex. Further, the yarn length difference between the polyester filament X and the polyester filament Y of the antistatic polyester composite false twisted textured yarn of the present invention is 5 to 20 ° / Torr, preferably 10 to 1 5 %. A good spunized feel is preferred in the range. When the fabric is produced by using the antistatic polyester composite false twisted textured yarn of the present invention described above, it may be necessary to apply a moderately kneaded yarn and then weave it into a desired structure. The obtained fabric exhibits an antistatic property which is impossible in the past weaving, and it is preferable to have a high-volume feeling of a faux yarn type, a soft touch and toughness on the surface, and a handle having a backlash property. Next, an embodiment of the third invention of the present invention will be described in detail. The antistatic polyester mixed yarn of the third invention of the present invention is composed of an antistatic polyester filament X and a polyester filament Y, and is characterized by satisfying the following conditions (i) to (vi). -30- 201040334 (i) Antistatic polyester fiber χ is a core-sheath type polyester conjugate fiber composed of polyester and copolymerized polyester B, based on 100 weights of aromatic polyester In the case of the portion, it contains 0.2 to 30 parts by weight of the right (a) the polyether shown in the following general formula (1), and the weight of the bismuth (5) and the weight of the polyester (b) and the polyester. f Reactive organic ionic compound made of antistatic polyester (ii) polyester filament X has a single yarn fineness of 1.5 dteX or less (iii) The friction band voltage of the mixed yarn is 2000 V or less; The mixed yarn is obtained by the order of air entanglement step and flavonoids: (v) The blend ratio of polyester filament X to polyester filament Y is: 4 ° (vi) polyester filament X The outer layer of the mixed yarn, polyfluorene constitutes the inner layer; R20-(CH2CH2〇)n(R'〇)m-R2 (1) wherein R1 is an alkyl group or a substituted carbon number of 2 or more僧R2 is a hydrogen atom and has a carbon number of 1 to 4 0 a monovalent hydrocarbon group, a monovalent hydroxy hydrocarbon of a carbon atom or a monovalent fluorenyl group η having a carbon number of 2 to 40 η is an integer, and m is an integer of 1 or more. constituting the antistatic polycondensation of the polyester mixed yarn of the present invention The ester is composed of a polyester core A composed of polyester A, and the sheath is a core-sheath polyester composite fiber composed of copolymerized polycondensation.

Further, the area ratio of the polyester A to the polyester B in the core/sheath portion in the cross section of the polyester multifilament yarn X must be in the range of 5: 95 to 80: 20. If the area ratio is 5: 9.5 hours, the antistatic performance of polyester a will be insufficient. If the ratio is 80:20, the antistatic polyester of the core will be applied when the alkali reduction is more than 10%. It will dissolve, and the antistatic performance will be lowered. At the same time, the strength of the stretched yarn will be reduced to 3.0 cN/dtex or less, and the strength as a cloth will be insufficient. Therefore, it is not suitable for the use of strength such as clothing, and the use is limited. Not good. When producing the polyester-mixed yarn of the present invention, first, as the polyester filament X', a conventional spinning device of the prior art is used, and the higher spinning speeds of the above-mentioned polyesters a and b are about 2000 to 5,000 m/min. Polyester undrawn yarn (generally referred to as intermediate oriented yarn POY) obtained after spinning, or low oriented polyester unstretched yarn which is spun at a spinning speed of about 1 000 m/min or oriented in the middle The yarn is stretched at a low magnification. On the other hand, as the polyester filament Y', a polyester filament extending yarn having a boiling water shrinkage ratio of 8.0% or more is preferably used, and a polyester filament extending yarn having a boiling water shrinkage ratio of 10 to 16% is more preferably used. Examples of the polyester filaments include a polyester filament yarn which is not thermally set, and a polyester which is a third component, for example, a polyester obtained by copolymerizing isophthalic acid to a degree of 5 to 15 mol%. Fibril extended yarns are preferred. The fineness of the polyester filament Y is preferably 2 to 1 Odtex. If it is less than 2dtex, the strength of the mixed yarn will decrease. When it exceeds 1 〇dtex, the handling becomes harder and it is not good. -32- 201040334 Fig. 3 is a schematic front view showing an example of the apparatus for manufacturing the mixed yarn of the present invention, by applying a relaxation heat treatment, pulling the polyester filament X' and the polyester filament γ automatically extended The entanglement is performed under excessive feeding by the staggered nozzle 3 provided between the supply roller 1 and the first take-up roller (heating roller) 2. In this apparatus, the first drawing roller 2 is heated and between the supply roller 1 and the first drawing roller 2, and the two kinds of polyester filaments are retracted in the first drawing roller 2 due to excessive feeding. The polyester filament X' is stretched from 0 on the roll by a relaxation heat treatment. Then, the second relaxation heat treatment is applied to the non-contact heater 5 provided between the first pull roller 2 and the second pull roller 4 to heat-fix the mixed yarn, and the container 6 is wound up. When the two kinds of polyester filaments are entangled, it is preferable to use an interlacing of 60 to 70 parts/m, so that the excessive feed rate is generally 1.0 to 1.5%. Further, as in the above-described example, when the first drawing roller 2 is heated and subjected to a relaxation heat treatment for automatically extending the above, it is preferable to reduce the apparatus, but it is preferable to the excessive feeding rate suitable for interlacing in the staggered nozzle 3. When the excessive feed rate (relaxation rate) which is automatically extended by the relaxation heat treatment is large, the drawing roller is further provided on the downstream side of the first drawing roller 2, and the predetermined relaxation heat treatment is also applied between the drawing rollers. can. Further, when the first take-up roll 2 is used as a heating roll, the diameter on the yarn exit side may be reduced to be smaller than the diameter of the yarn entry side of the roll 2, and the predetermined excessive feed rate (relaxation) may be applied to the roll. Rate) Heat treatment. The temperature and the excessive feed rate (flaze rate) of the self-expanding polyester filament X 'automatically extend, depending on the polyester filament X, the yarn used, for example, a spinning speed of 3 000 - 3 500 m / min The medium-33-201040334 oriented yarn (ΡΟΥ) under the spinning, when the first drawing roll (heating roll) 2 is subjected to the slow heat treatment, the surface temperature of the roll is preferably 1 ο 0~1 30 °C. The excessive feed rate (relaxation rate) is preferably 1.0 to 1.5%. By the tempering heat treatment of the second stage of the non-contact heater 5, the heat-fixing treatment for the mixed yarn of the present invention to impart the characteristics of a carding fabric suitable for the high-reverse felting felt is 2,102⁄4~ 240. (: It is preferably treated at an excessive feed rate of 1.5-2.0%, and the treatment time is generally 0.01 to 0.30 seconds. The boiling water shrinkage of the obtained polyester mixed yarn is generally about 5 to 13%. As a non-contact heater 5. A slit heater, a tube heater, etc. can be used. In the mixed yarn of the present invention, the polyester filament X' and the polyester filament γ' which are automatically elongated by the relaxation heat treatment are entangled and then subjected to a relaxation heat treatment.

201040334 該鰭狀部容易集中加工張力，故產生纖維截面之部分性破壞’無法形成充分毛細管，使得吸水性能不充分。又，延伸假撚步驟中斷紗（加工斷紗）或毛絮亦頻繁產生。且，即使突起係數爲0.3〜0.7的鰭狀部，於單纖維截面具有1〜2個該鰭狀部時，封閉於內側之纖維截面部分最多僅可形成1個，故無法表現充分毛細管現象，使得吸水性能不足。又，布帛的觸感亦成爲平坦如紙一般。另一方面，若超過8個時，延伸假撚加工時會產生對鰭狀部之加工張力集中’引起纖維截面之部分破壞，無法形成充分之毛細管’使得吸水性能不足。又，在延伸假撚步驟之斷紗 (加工斷紗）或毛絮會頻繁發生。且，突起係數若未達〇·3的鰭狀部超過8個存在時亦可。以上說明之本發明的抗靜電性芯鞘型聚酯複合纖維，藉由調整公知芯鞘複合紡紗機之吐出孔而可作成，但例如藉由改變芯部形成用圓形吐出孔之半徑（圖6之a2 )、自該圓形吐出孔之中心點至鰭狀部形成用吐出孔的先端部之長度（圖6的b2)等，可任意設定爲纖維截面的突起係數爲0.3〜0.7。又，即使藉由改變SPIN BLOCK的溫度及/或冷卻風量，可某程度地控制纖維截面之突起係數。又，本案的第1發明〜第4發明中所使用的抗靜電性芯鞘型聚酯纖維爲，於單紗長度方向呈直交的截面爲扁平形狀，於縱方向具有接合3〜6個圓截面單紗之形狀，於接合部分形成中縮部爲必要。（參照圖7) 一般接合2個圓截面單紗、或圓截面單紗之形狀的情 -42- 201040334 況爲，織物中的芯鞘型聚酯扁平截面形態難以形成，經紗與緯紗所形成之大，其結果恐怕無法得到自該空隙通。相反地，若超過7個時，製紗性成其次，所謂前述中縮部爲如圖8 變短的部分。對於該中縮部之凹部深値（B )與最小値（C )之比B / C成| 0 1.1以上）的深度爲佳。又，圖8表的例子，亦可僅於一方側部形成凹部必須爲2處以上，中縮部爲1處以下得到充分光之亂射或透過光之折射，防辨識性故不佳。該中縮部的個數爲特別限定，若考慮到製紗性則以3〜5 示中縮部爲2個之例子。上述抗靜電性芯鞘型聚酯纖維因〇扁平，進行製造織物時，藉由織物組有緻密且往寬方向擴充。其結果以經隙變小，減低自該空隙的光通過量。微量通過光引起衍射，鄰接的通過光優良之防辨識效果。且，將纖絲的橫截面形狀成爲具截面形狀，且使消光劑的含有量爲特之平坦扁平截面紗、圓截面紗、三角亂反射或透過纖絲之透過光的折射變纖維往外擴充的集合空隙（組織空隙）變過光的充分防辨識性爲困難而不佳。所示模式中短邊長度度，在短邊長度最大 I 1.05以上（較佳爲示凹部形成於兩側部。而該中縮部的個數時，對於中縮部無法無法得到令人滿足之 2處以上即可，並無處爲佳。且，圖8表該橫截面形狀爲特殊織點之接著壓力，具紗與緯紗所形成之空此時，通過該空隙之彼此干渉而無法得到有特定中縮部之扁平定量以下，與同纖度截面紗相比較，光之大，可於無損害到採 -43- 201040334 光性下得到優良防辨識效果。又，芯鞘型聚酯扁平截面纖維因具有往寬方向之擴充，故彎曲剛性，變低，並賦予柔軟觸感（handling)。且對於織物組織點，因中縮部（凹部）男與其他紗接觸’故經紗與緯紗之摩擦較少，比具有平坦扁平形狀者更可得到進一步之柔軟觸感。【實施方式】 [實施例] 以下舉出實施例及比較例，對於本發明做進一步具體說明，但本發明的範圍以不超過其要旨下並未受到任何限定。且，實施例中之各特性値以下述方法進行測定。 (I.本案第1發明中，共聚合聚酯B係爲共聚合有機系紫外線吸收成分之聚酯的實施例） (1 )固有黏度溶解於原氯酚，使用烏別洛特黏度計在3 5 °C下進行測定。 (2 )紡紗斷紗在複合紡紗設備進行1星期之熔融紡紗，技術斷紗之次數，將1日每1錘的紡紗斷紗次數作爲紡紗斷紗。但，人爲或機械因素所引起的斷紗則自斷紗次數除外。 -44- 201040334 (3 )延伸假撚斷紗以帝人製機製216錘建HTS-15V (在2加熱器假撚加工機進行非接觸式加熱器者），施予連續一星期的延伸假撚加工’將延伸假撚機1台·每日之斷紗次數作爲延伸假撚斷紗。但’繫紗之前後的斷紗（打結斷紗）或自動替換時的斷紗等人爲或機械要因所引起的斷紗則自斷紗次數除外。〇 (4 )延伸斷紗實施連續一星期的延伸加工，延伸機1台·每日的斷紗次數作爲延伸假撚斷紗。但，繫紗前後的斷紗（打結斷紗）或自動替換時的斷紗等人爲或機械要因所引起的斷紗自斷紗次數除外。 (5 )複折射率〇依據常法，使用光學顯微鏡與補償器（compensator )’由纖維表面所觀察到的偏光遲延求得。 (6 )紗條之強度、延伸度依據〗IS L-1013-75進行測定。 (7 )捲縮率對於聚酯假撚加工紗試品施予〇.〇44cN/dtex的張力並捲取於絞絲框架，作成約3 3 OOdtex之絞絲。於該絞絲之 -45 -

The blend ratio of polyester filament X-34-201040334 to polyester filament γ (weight ratio) is preferably from the viewpoint of darkness and protrusion. The weight ratio is preferably in the range of 8:2 to 5:5. . Preferably it is 8~6: 2~4. In the range, the touch, the feeling of touch, the soft feeling, the strength, and the like are balanced, and the cloth has good flexibility, reversal, and touch. Further, 'the obtained mixed yarn of the present invention or the woven fabric made of the fiber is heat-treated at a temperature of 1 ° C or higher, and the structure is stabilized and the polyethylene oxide contained in the fiber is It is preferred that the polyether, and the migration of various additives as necessary, contribute to the suitability of the alignment. Further, depending on the necessity, a tempering heat treatment or the like can be used. Further, it is preferable to apply a suitable hydrophilization treatment to the antistatic polyester mixed yarn of the present invention or the woven fabric produced by the fiber as necessary. As the post-hydrophilization treatment, for example, chiral copolymerization of terephthalic acid and/or isophthalic acid or lower alkyl esters thereof, polyester polyether with lower alkanediol and polyalkylene glycol can be employed. Preferably, the method of treating the aqueous dispersion with a hydrophilic monomer such as acryl or methacrylic acid, or the method of sodium chlorination, or the like, is preferably carried out. The antistatic property of the mixed yarn of the present invention is required to have a friction band voltage of 200 〇 V or less. If it is 2000V or more, the static electricity is large, making it uncomfortable or unsafe when worn. Next, an embodiment of the fourth invention of the present invention will be described in detail. The fourth invention of the present invention is a method for producing an antistatic polyester mixed yarn, which has an elongation (ELA) of 80% or more, an elastic recovery ratio (ERA) of 50% or less at a 10% elongation, and an elongation rigidity ratio (£). ?4)) 5.89〇?&-35- 201040334 Hereinafter, the degree of crystallization (ΧρΑ) is 25% or more, the boiling water shrinkage rate BWSA is 3% or less, and the thermal stress (TSA) at 160 °C is 0.4 4 mN/ Below dtex, after the heat-resistant polyester filament X' satisfying the requirements of the following (i) to (ii) is subjected to a heat treatment, the elongation (ELB) is 40% or less, and the elongation rigidity (EMB) is 7.85 GPa. Above, the boiling water shrinkage rate (BWSB) is 5% or more, and the polyester fiber Y' of the thermal stress (TSB) of 0.88 mN/dtex or more in the 1 60 °C is bonded to the polyester composite fiber X' and the polyester. The weight ratio of the multifilament yarn Y' is 45/5 5 to 70/30, and then the treatment is carried out. (i) Antistatic polyester multifilament yarn X' is a core-sheath type polyester composite fiber composed of a copolymer of polyester B and a copolymerized polyester B, and a poly A system is derived from aromatic polyester 1 In the case of 〇〇 by weight, it contains 0.2 to 30 parts by weight of the antistatic agent, (a) a polyoxylated polyether represented by the following general formula (1), and 5 to 10 parts by weight of (b) with 〇·〇. The polyester having a substantially non-reactive organic ionic compound and having an antistatic polyester has a single yarn fineness of 1.5% or less. R20-(CH2CH2〇)n(R'〇)m-R2 (1) wherein R is an alkylene group having 2 or more carbon atoms or a substituted alkyl group R2 is a hydrogen atom and having 1 to 40 carbon atoms a monovalent hydrocarbon group, a monovalent hydroxy hydrocarbon having 2' carbon atoms or a monovalent fluorenyl group having a carbon number of 2 to 40 is an integer of 1 and m is an integer of 1 or more. Ester-based olefins 40-up-36- 201040334 The antistatic polyester fiber roving yarn constituting the polyester-mixed yarn of the present invention, wherein the core portion is composed of polyester A, and the sheath portion is composed of copolymerized polyester B. In the core-sheath type polyester composite fiber, the polyesters A and B used in the core-sheath type composite fiber of the first invention of the present invention are the same polyester. The above-mentioned antistatic polyester filament X' The elongation (ELA) is 80% or more, preferably 100 to 200%, and the elastic recovery rate (ERA) at 10% elongation is 50% or less, preferably 40% or less. The EMA is 5.89 GPa (600 kg/mm2) or less, preferably 1.96 to 4.91 GPa (200 to 500 kg/mm2), and the degree of crystallization (??) is 25% or more, preferably 36 to 60%. As necessary, the heat in 1 60 ° C should be (TSA) is required to be 0.44 mN/dtex (50 mg/de) or less, and the boiling water shrinkage ratio (BWSA) is required to be 3% or less. When such characteristics are exhibited, the antistatic polyester filament X' is heated and mixed. In the case of the yarn, the yarn is in a floating state, and the volume is increased without stress burden even in the direction of elongation. As a result, it is possible to suppress the occurrence of collapse. The antistatic polyester fiber filament having such characteristics For example, using the conventionally known composite spinning device, the polyesters a and b are melted at a temperature of 280 to 300 ° C, melted and spun from a spinning take-up head, and spun yarns are cooled and solidified. The oil-imparting agent is used as an interlacing device in which the air injection hole is 3 or more holes, and the air having a jet pressure of 11 to 33 MPa is supplied to the preheating roller and the extension roller which are set to be below the glass transition temperature of the polyester. (Preheating roller pulling speed: 1 5 00~2 5 00m/min, extension ratio: 1·1~1.5), once it is wound into the winding machine. -37- 201040334 Next, the obtained extended yarn can be passed at speed 5 00~1 400m/min heating to 70~110 °C preheating roller and The non-contact heater set to 170 to 240 ° C is obtained by applying a heat setting (expansion ratio of 1 or less to a relaxation heat setting) at a stretching ratio of 0.8 to 1.1 times. Next, the other of the mixed yarns constituting the present invention The component polyester filament Y' (sometimes referred to simply as the filament Y') is mainly intended to bear the load in the extended direction and to maintain the shape stability or the stability in the post-processing step, and the elongation (ELB) is 40% or less, preferably 30% or less is necessary, and the elongation rigidity (EMB) is 7.85 GPa (800 kg/mm2) or more, preferably 8.83 to 14.7 GPa (900 to 1500 kg/mm2). Moreover, it is necessary to have a good volume property by heat treatment, and the boiling water shrinkage ratio (BWSB) is 5% or more, preferably 7 to 20%, and is required to be the same as the cloth after the cloth is equal to heating. The ester fibril X' can suppress the tactile sensation without stress, and the thermal stress (TSB) at 160 °C is 0.88 mN/dtex (100 mg/dtex) or more, preferably 1 · 7 6 m N/dt ex (200 mg/dt ex ) Above is necessary. When the filament Y' having such characteristics is extended, for example, an unstretched fiber made of the above polyester, the elongation temperature or the stretching ratio can be appropriately adjusted. For example, the elongation or the rigidity can be adjusted by the stretching ratio. The boiling water shrinkage rate can be adjusted by the heat setting conditions at the time of extension. In particular, when high shrinkage is desired, it is appropriate to have no plate extension or the like. The thermal stress can be further adjusted by the stretching speed of the unstretched fiber by the stretching ratio or the heating temperature at the time of extension. However, if the spinning take-up speed is too high, the stress after the extension of the heat-38-201040334 may not be increased, so it is not more than 2500 m/min, preferably less than 1 70 0 m/min. The extension of the extended fibers is preferred. Further, as another method for adjusting these characteristics, there is a method of copolymerizing a polyester with a third component. For example, when the isophthalic acid component is copolymerized, it is easy to obtain a product having high shrinkage properties. In the mixed yarn of the present invention, after the above-mentioned antistatic polyester filament X' is subjected to a relaxation heat treatment, it is necessary to carry out entanglement and mixing with the polyester filament Y'. It is not preferable to impart thermal deformation to the yarn Q strip, for example, it is not preferable to apply false twist crimping, and this method cannot obtain the collapse recovery effect. The reason is that the first reason is that the heat treatment, elongation, twisting, etc. in the false twist crimping process change the physical properties of the polyester filament X', reduce the elongation, increase the thermal stress, and improve the elastic recovery rate, or When the polyester filament X' is crimped, the yarn is entangled with the adjacent yarn to increase the electric resistance, and when it becomes a fabric such as a woven fabric, the yarn which is deviated from the position in the woven fabric is difficult to return to the original state, and the yarn is easily broken. Further, when the air is ejected by the air jet, the air jet direction may be a direction perpendicular to the crepe or along the direction of the yarn, and the former may obtain a product having a relatively good gloss, and the latter may obtain a relatively soft touch product. . Further, although an excessive feed difference can be provided between the polyester filament X' and the polyester filament γ' for air-combination processing, if the difference is too large, a large number of loops are likely to occur, so that the same excessive feed rate is generally employed. In the composite ratio (mixing ratio) of polyester filament X' and polyester filament Y', the weight ratio of polyester filament X' to polyester filament Y' is 45/5 5~70/30 As necessary. In particular, when the ratio of the polyester filament x' is large, the effect of -39-201040334 of the present invention is easily produced, so that the weight ratio of the polyester filament X' to the polyester filament Y' is 5 5/45 to 70/ 30 is especially good. Further, as for the polyester filaments X' and the polyester filaments Y', one yarn is described as an example. Of course, two or more yarns may be used, that is, fibers satisfying the physical properties of the present invention. Yes, any number of slivers can be used. Further, even if the third yarn which does not satisfy the above physical properties of the present invention is added, it may be compounded. For example, a metal-plated fiber or a fiber mixed with carbon particles can be used to impart conductivity. However, when the ratio of the fiber is too large, the improvement of the recovery property of the object of the present invention is not sufficient, so the utilization rate is 30% higher. good. Further, the antistatic core-sheath type polyester fiber used in the first to fourth inventions of the present invention has 3 to 8 protrusion coefficients defined by the following formula in the cross section of the single fiber of 〇. 3 to 0.7. It is preferable that the fin portion protrudes outward from the core portion of the fiber section. Protrusion coefficient = (al-bl) /al a 1 : length from the center of the inscribed circle of the inner wall of the fiber section to the apex of the fin portion b 1 : radius of the inscribed circle of the inner wall of the fiber section (inner core outer end Round) The polyester composite fiber of the present invention having such characteristics and cross-sectional shape can withstand the squeezing of the extended false twisting process, and the elongation false twist can be reduced even under the general conditions, thereby reducing the yarn breakage during the extension false twisting process ( The processing is performed under the generation of the yarn breakage and the batt, and the polyoxyalkylene glycol-based antistatic agent can be sufficiently elongated in the fiber axis direction, so that the antistatic property is good. Further -40-201040334 The obtained cross-section of the false-twisted processed yarn has a flat cross-sectional shape which is moderately dispersed in the direction of the fiber axis, and has a fiber cross section which is not completely entangled in the fiber axis direction, and forms a fiber aggregate having a large inter-fiber gap. The water absorption and quick-drying performance and the effect of improving the washing durability of the performance are also achieved. Further, the fiber cross-section is flat in the fiber axis direction and has a moderately dispersed fiber aggregate and has a natural dry feeling as a fabric. Further, the above-mentioned antistatic core-sheath type polyester fiber is excellent in water absorption performance, antistatic property, and step stability. Although this reason is not clear, it is estimated that a hydrophilic polyoxyalkylene glycol type and an ionic compound which are used as an antistatic agent in the water absorption of the capillary phenomenon of a specific shape protrusion alone can be used as a core antistatic agent. The improvement is improved, and when the spinning is extended, especially when the elongation between the fibers is small, the antistatic agent is uniformly stretched in the direction of the fiber axis, and has the correct aspect ratio, and also becomes a step of generating less fluff. Good stability. The single fiber cross-sectional shape of the antistatic core-sheath type polyester fiber (specific example 图 is Fig. 5) has a protrusion coefficient of 0.3 to 0.7, preferably 〇·4 to 〇·6. The number of the fin portions (1 in Fig. 5) protruding outward from the core portion of the fiber section is 3 to 8, and it is preferable that 4 to 6 shapes are present. The fin portion having a projection coefficient of less than 〇·3 does not have a function of extending a sufficient capillary gap of the fiber cross section after the processing of the false twist, and does not exhibit water absorption and quick-drying performance. Further, since such a short fin portion has a small anchor effect when the cloth is applied to the water absorbing agent, the washing durability of the treating agent tends to decrease. Moreover, the touch of the cloth is also flat and paper-like. On the other hand, when the fin portion having a protrusion coefficient of more than 0.7 is the 'extended false twisting process, the fin portion tends to concentrate the processing tension due to the -41 - 201040334, so that partial breakage of the fiber cross section is generated. Water absorption performance is not sufficient. Further, the step of interrupting the false twisting process interrupts the yarn (machining yarn breakage) or the batt is also frequently generated. Further, even if the fin portion having a projection coefficient of 0.3 to 0.7 has 1 to 2 fin portions in the single fiber cross section, the fiber cross-section portion enclosed inside can be formed at most, so that sufficient capillary phenomenon cannot be expressed. The water absorption performance is insufficient. Moreover, the touch of the cloth is also flat as paper. On the other hand, when there are more than eight, the processing of the tension in the fin portion is concentrated during the processing of the false twisting, and partial breakage of the fiber cross section is caused, and a sufficient capillary cannot be formed, so that the water absorption performance is insufficient. Also, the yarn breakage (machining yarn breakage) or batt in the extension false twisting step occurs frequently. Further, if the protrusion coefficient is less than 8 in the presence of more than 8 fins. The antistatic core-sheath type polyester conjugate fiber of the present invention described above can be produced by adjusting the discharge hole of a known core-sheath composite spinning machine, but by, for example, changing the radius of the circular discharge hole for core formation ( In the a2) of FIG. 6, the length from the center point of the circular discharge hole to the tip end portion of the fin-forming discharge hole (b2 in FIG. 6) can be arbitrarily set so that the protrusion coefficient of the fiber cross-section is 0.3 to 0.7. Further, even by changing the temperature of the SPIN BLOCK and/or the amount of cooling air, the protrusion coefficient of the fiber cross section can be controlled to some extent. Further, the antistatic core-sheath type polyester fiber used in the first invention to the fourth invention of the present invention has a flat cross section which is orthogonal to the longitudinal direction of the single yarn, and has 3 to 6 circular cross sections in the longitudinal direction. The shape of the single yarn is necessary to form the intermediate portion at the joint portion. (Refer to Fig. 7) In general, the shape of the single-segment single-yarn or the single-yarn single-yarn is combined. The flat-sheath form of the core-sheath type polyester in the fabric is difficult to form, and the warp and weft are formed. Large, the result may not be able to get from the gap. On the other hand, when it exceeds seven, the yarn-making property is second, and the above-mentioned middle-shrinkage portion is a portion which is shortened as shown in Fig. 8. It is preferable that the depth of the concave portion (B) and the minimum 値 (C) ratio B / C becomes | 0 1.1 or more in the concave portion of the middle portion. Further, in the example of the table of Fig. 8, the concave portion may be formed in only one side portion, or the intermediate portion may be one or less, and the sufficient light may be scattered or the light may be refracted, so that the visibility is not good. The number of the constricted portions is particularly limited, and in the case of the yarn making property, the number of the constricted portions is two in the range of 3 to 5. When the above-mentioned antistatic core-sheath type polyester fiber is flattened, the fabric is densely formed and expanded in the width direction when the fabric is produced. As a result, the gap becomes smaller, and the amount of light passing through the gap is reduced. A small amount of light is diffracted by light, and the adjacent passing light has an excellent anti-identification effect. Further, the cross-sectional shape of the filament is a cross-sectional shape, and the content of the matting agent is specifically expanded by a flat flat cross-section yarn, a circular cross-section yarn, a triangular chaotic reflection, or a refracted fiber that transmits light through the filament. The sufficient anti-recognition of the collection void (tissue void) to change the light is difficult and difficult. In the mode shown, the length of the short side is at most 1.05 or more in the length of the short side (preferably, the concave portion is formed on both sides), and the number of the middle and the small portion cannot be satisfied for the middle portion. There are no more than two places, and the cross-sectional shape of Fig. 8 is the pressure of the special weaving point. The space formed by the yarn and the weft yarn is not able to be obtained by the gaps. The flatness of the specific medium-shrinkage part is lower than that of the same-denier cross-section yarn, and the light is large, and the excellent anti-identification effect can be obtained without damage to the light of -43-201040334. Also, the core-sheath type polyester flat section fiber Because it has an expansion in the width direction, it bends rigidly and becomes low, and gives a soft touch. And for the fabric tissue point, since the meniscus (recess) is in contact with other yarns, the friction between the warp and the weft is higher. When the amount is small, a softer touch is obtained than a flat shape. [Embodiment] [Embodiment] Hereinafter, the present invention will be further described in detail by way of examples and comparative examples, but the scope of the present invention is The present invention is not limited in any way. Further, each characteristic in the examples is measured by the following method. (I. In the first invention of the present invention, the copolymerized polyester B is a copolymerized organic ultraviolet absorber. Example of the polyester of the component) (1) The intrinsic viscosity is dissolved in the original chlorophenol, and the measurement is carried out at 35 ° C using a Ubbelite viscometer. (2) Spinning yarn breakage is performed for one week in the composite spinning equipment. For the melt spinning, the number of technical yarn breaks is the number of yarn breaks per 1 hammer per day as the yarn breakage. However, the yarn breakage caused by artificial or mechanical factors is excluded from the number of yarn breaks. - 201040334 (3) Extend the false twisted yarn to build the HTS-15V with the Teijin system 216 (for the non-contact heater in the 2-heater false twisting machine), and give the extension for one week of continuous false twist processing. Extend the number of false twisting machines and the number of yarn breaks per day as the extension false twist yarn. However, it is caused by artificial or mechanical factors such as yarn breakage before the yarn is tied (broken yarn breakage) or yarn breakage during automatic replacement. The yarn breakage is excluded from the number of yarn breaks. 〇 (4) Extended yarn breakage is carried out for one week. Extending processing, one extension machine and the number of yarn breaks per day are used as the extension false twist yarn. However, the yarn breakage before the yarn is broken (knotted yarn breakage) or the yarn breakage during automatic replacement is caused by artificial or mechanical factors. The yarn breakage is excluded from the number of yarn breaks. (5) The complex refractive index is determined according to the normal method using an optical microscope and a compensator's polarization retardation observed on the surface of the fiber.

(Yarning) The yarn forming is carried out as follows: The dried polymer is melted in a spinning apparatus by each conventional method, and supplied to a two-component composite spinning head via a gear pump. -71 - 201040334 Core and sheath The ratio of the polymer was set to the core/sheath = 3 〇 / 7 〇. At the same time, the molten polymer supplied to the core and the sheath was 'spinning from a circular composite spinning hole having 72 nozzle apertures of 0.25 mm. The wire drawing head is cooled and solidified by the cooling wind of the self-interlacing flow spinning cylinder. The spinning oil agent is applied as a sliver and bundled at a speed of 300 m / mi η to obtain a polyester intermediate oriented yarn of 90 dtex/72 filament (single fiber denier: 1.25 dtex) POY) (polyester multifilament yarn X'). On the other hand, 'polyethylene terephthalate isophthalic acid copolymerized polyester having an intrinsic viscosity of 0.64 (isophthalic acid is 〇m〇i% copolymerized) is melted at 280 ° C The unstretched yarn which is spun at a spinning speed of 1 450 m/min is extended to 2.9 times at 8 7 ° C to obtain a boiling water shrinkage of 15% and 55 dtex/12 filament (single fiber fineness: 4.6 dtex). Heat shrinkable polyester yarn (heat shrinkable polyester fiber Y yarn Y). Using the polyester multifilament yarn X' and the heat-shrinkable polyester multifilament yarn γ', a polyester mixed yarn was produced in the apparatus shown in Fig. 3. That is, the two polyester multifilament yarns X' and γ' are aligned, and the staggered nozzles 3 provided between the supply roller 1 and the first drawing roller (heating roller having a surface temperature of 120 ° C) 2 are 600 m. The speed of /min is supplied at an excessive feed rate of 1.2%, and it is entangled by a pressure of 2.0 kg/cm2, giving an interlacing of 65 parts/m. And the blend ratio of polyester multifilament yarn X' and polyester composite filament Y' is 62: 38 〇 second, at a super-feed rate of 1.2%, directly to the heating roller with a surface temperature of 120t (2) The number of windings of the yarn is 8 times, the heat treatment of the polyester fiber yarn X' is automatically extended, and the polyester fiber composite fiber-72-201040334 Y' is heat-shrinked, and then set. The slit heater 5 between the heating roller 2 and the second drawing roller 4 is subjected to a second relaxation heat treatment at 230 ° C at an excessive feed rate of 1.8% for 5 seconds, and is thermally fixed. After the second take-up roll (cold roll) 4 was wound twice, the container 6 was taken up as a mixed yarn of 150 dtex/84 filaments. The chargeability of the obtained mixed yarn was a friction band voltage of 900V. In the production of the polyester mixed yarn, the yarn contact 0 of the slit heater 5 was not confirmed, and the yarn breakage was 1 曰, and the hammer was only 1 time. The obtained mixed yarn was woven into a flat fabric of 60 sheets/cm and a latitude of 35 sheets/cm, and dyed black by a conventional method at 135 ° C for 60 minutes. The resulting dyed fabric has a high backlash at the level 1 and is a wool-like fabric with a bulky feel, and no static electricity is generated when worn.

The obtained dyed fabric is excellent in antistatic property, but has less shrinkage in the relaxation heat treatment, so that the polyester composite fibril is not sufficiently covered by the polyester composite filament X, and it is not a good one (level 1). [Comparative Example VI-4] In Example VI-1, the same procedure was carried out except that the polyester multifilament yarn X was not added with an antistatic agent. The fabric of the obtained mixed yarn was used as the level 1 and had a bulky feeling and good reversal property but had no antistatic property and generated static electricity when worn. [Comparative Example VI-5] In Example VI-1, the same procedure was carried out except that the amount of the polyoxygenated polyacid added was changed to 0.1 part. The fabric of the obtained mixed yarn was used as the level 1 feeling of bulkiness and high reversibility, but no antistatic property was generated. [Comparative Example VI-6] In Example V I-1, the relaxation heat treatment was not carried out, and a mixed yarn was produced in a general false twisting step.
