Description
POLYESTER-BASED FIBER FOR ARTIFICIAL HAÏR AND
HAÏR ORNAMENT PRODUCT INCLUDING THE SAME
Technical Field [0001] The présent invention relates to a polyesterbased fiber for artificial haïr capable of being used as an alternative to human haïr and a hair ornament product including the polyesterbased fibei* for artificial hair. Specifically, the présent invention relates to a polyesterbased fiber for artificial hair having gloss close to that of human hair and a hair ornament product including the polyesterbased fiber for artificial hair.
Background Art [0002] In hair ornament products such as a hairpiece, a hair wig, crepe hair, a hair band, and doll hair, human hair has been conventionally used. However, in recent years, it is becoming difficult to obtain human hair, and the importance of fibers for artificial hair, instead of human hair, is increasing. As a fiber material for artificial hair, modacrylic fibers hâve been used in most cases, taking advantage of the feature of flame retardancei however, the modacrylic fibers do not hâve sufficient heat résistance. Then, it has been proposed that polyesterbased fibers excellent in heat résistance be used as fibers for artificial hair. However, the polyesterbased fibers are usually spun by melt spinning, and hence hâve a very smooth fiber surface and peculiar mirrorsurface gloss although having sufficient heat résistance. Therefore, when the polyesterbased fibers are used for hair ornament products to be attached to human hair, such as a hair wig or a hairpiece, a feeling of wrongness is caused.
[0003] Then, various methods for ameliorating gloss of the polyesterbased fibers hâve been studied. For example, Patent Document 1 proposes that a brominated epoxy flame retardant and organic fine particles and/or inorganic fine particles be added to a polyester resin. Patent Document 2 piOposes that brominated epoxy flame retardant having a numberaverage molecular weight of20,000 or more be added to a polyester resin. Patent Document 3 proposes that a brominated epoxy flame retardant and a reaction accelerator be added to a polyester resin. Patent Document proposes that a brominated epoxy flame retardant and an ester interchange suppressor be added to a polyester resin.

Disclosure of Invention
Problème to be Solved by the Invention [0005] However, in the proposai of Patent Document 1, the brominated epoxy flame retardant is finely dispersed in libers due to its high compatibility with the polyester resin. Therefore, the addition of the brominated epoxy flame retardant is not sufficiently reflected on the unevenness of a fiber surface, and the gloss is suppressed 15 mainly by the organic fine particles and the inorganic fine particles. Thus, there still remains room for improvement in ensuring sufficient color development, and there also remains room for improvement in suppressing the gloss after ensuiing spinning stability. In Patent Document 2, the gloss is adjusted by finely dispersing the brominated epoxy flame retardant in polyester through use of a brominated epoxy 20 flame retardant having a numberaverage molecular weight of20,000 or more.
However, there still remains room for improvement in reaching a level required on the market. In Patent Document 3, the compatibility between the brominated epoxy flame retardant and the polyester resin is increased by accelerating the ester interchange reaction therebetween through use of the reaction accelerator. However, 25 the brominated epoxy flame retardant is more finely dispersed, and hence it cannot be exactly said that the effect of suppressing the gloss is enough. Furt her, in Patent
Document 4, the compatibility between the brominated epoxy flame retardant and the polyester resin is decreased with the ester interchange suppressor. However, an aggregation size of the brominated epoxy flame retardant is still small merely with the 30 decrease in compatibility, and the effect of reducing the gloss is not enough. Further, when the ester interchange suppressor is added excessively, there is a problem in that a spinning property is remarkably degraded. yyS' [0006] In order to solve the above* mentioned conventional problème, the présent invention provides a polyesterbased fiber for artificial hair having gloss close to that of human hair and a hair omament product including the same.
Means for Solving Problem [0007] The présent invention relates to a polyesterbased fiber for artificial hair formed of a polyester resin composition, in which the polyester resin composition contains 5 to 40 parts by weight of a brominated epoxy flame retardant and 0.05 to 5 parts by weight of an acidic compound with respect to 100 parts by weight of a polyester resin, the polyester resin is one or more kind of resin selected from the group consisting of polyalkylene terephthalate and copolymerized polyester containing polyalkylene terephthalate as a main component, and the acidic compound is an acidic phosphorus-based compound having a pH of 3.5 or less.
[0008] The présent invention also relates to a hair omament product including the above-mentioned polyesterbased fiber for artificial hair.
Effects of the Invention [0009] The présent invention can provide a polyesterbased fiber for artificial hair having gloss close to that of human hair and a hair ornament product including the polyesterbased fiber for artificial hair by adding a brominated epoxy flame retardant and an acidic phosphorus*based compound having a pH of 3.5 or less to polyesterbased fibers for artificial hair.
Brief Description of Drawings [0010] [FIG. 1] FIG. 1 is a graph showing molecular weight distributions obtained by conducting a GPC measurement of each brominated epoxy flame retardant in polyesterbased fibers in one example of the présent invention and one comparative example.
Description of the Invention [0011] The inventors of the présent invention earnestlv conducted repeated studies so as to solve the above-mentioned problème. As a resuit, the inventors of the présent invention found that a polyesterbased fiber for artificial hair, which is excellent in gloss required of fibers for artificial hair and has satisfactory flame retardance and a spinning property while keeping fiber physical properties such as heat résistance and strength and élongation of ordinary polyesterbased fibers, is obtained through use of a resin composition préparée! by adding a brominated epoxy flame retardant and an acidic phosphorus’based compound having a pH of 3.5 or less to a polyester resin, and thus achieved the présent invention. Further, the inventors of the présent invention found that combing properties, flame retardance, and a spinning property are further enhanced by adding a thickener. It should be noted that, in the case of a non-phosphorous acidic compound having a pH of 3.5 or less, the effect of accelerating the décomposition of the polyester resin is veiy large compared with that of the acidic phosphorus’based compound, and the viscosity of a polyester resin composition is remarkably decreased, which makes it impossible to obtain a yarn normally during spinning.
[0012] In general, a brominated epoxy flame retardant is fînely dispersed in a polyester resin during melt kneading due to its high compatibflity with respect to the polyester resin. Therefore, when the polyester resin composition containing the polyester resin and the brominated epoxy flame retardant is fiberized, the brominated epoxy flame retardant is drawn in a spindle shape having a thickness of 0.02 pm or less and an aspect ratio of 10 times or more, and thus hardly influences the shape of a fiber surface layer portion. Therefore, polyesterbased fibers to be obtained hâve a smooth fibei’ surface and high gloss peculiar to plastic. In the présent invention, by using the brominated epoxy flame retardant and the acidic phosphoi’us-based compound having a pH of 3.5 or less, the following effects are obtained: the acidic phosphorus’based compound serves as a ring-opening catalyst of an epoxy group at a molecular end of the brominated epoxy flame retardant, thereby polymerizing molécules of the brominated epoxy flame retardant through an epoxy group and binding the phosphorus’based compound and two or more epoxy groups to each other through an ester bond. Therefore, the molecular weight of the brominated epoxy flame retardant increases, the dispersibility of the brominated epoxy flame retardant is degraded, and the brominated epoxy flame retardant aggregates to hâve a thickness of 0.05 pm or more. Thus, the surface layer portion of the fibers is allowed to express roughness to reduce gloss to a level dose to that of human haïr.
[0013] The polyesterbased fiber for artificial hair of the présent invention refers to fibers formed of the polyester resin composition. In general, the polyesterbased fiber for artificial hair can be formed by melt spinning the polyester resin composition. It should be noted that the polyester resin composition is generally melt spun after melt kneading. The polyester resin composition contains a polyester resin (hereinafter, also referred to as “Acomponent”), a brominated epoxy flame retardant (hereinafter, also referred to as “B component”), and an acidic phosphorus’based compound having a pH of 3.5 or less (hereinafter, also referred to as “C component”).
[0014] The polyester resin is one or more kind of resin selected from the group consisting ofpoly alkylene terephthalate and copolymerized polyester containing polyalkylene terephthalate as a main component. Although no particular limitation is imposed on the polyalkylene terephthalate, examples thereof include polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, and polycyclohexanedimethylene terephthalate. Although no particular limitation is imposed on the copolymerized polyester containing polyalkylene terephthalate as a main component, examples thereof include copolymerized polyester containing polyalkylene terephthalate such as polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, or polycyclohexanedimethylene terephthalate as a main component, and containing another copolymer component. The term “main component” as used herein means containing 80 mol% or more, and the term “copolymerized polyester containing polyalkylene terephthalate as a main component” refers to copolymerized polyester containing 80 mol% or more of polyalkylene terephthalate.
[0015] Examples of another copolymer component include: polycarboxylic acid such as isophthalic acid, orthophthalic acid, naphthalenedicarboxylic acid, paraphenylenedicarboxylic acid, trimellitic acid, pyromellitic acid, succinic acid, glutaric acid, adipic acid, subeiic acid, azelaic acid, sebacic acid, and dodecanedioic acid, and dérivatives thereof dicarboxylic acid containing a sulfonate such as 5-sodiumsulfoisophthalic acid and dihydroxyethyl 5-sodiumsuJfoisophthalate! 1,2-propanediol; 1,3-piOpanediol; 1,4-butanediol! 1,6-hexanediol! neopentylglycol; 1,4-cyclohexanedimethanol! diethylene glycol! polyethylene glycol! trnnethylolpropane! pentaerythritol! 4-hydroxybenzoic acid, and ε-caprolactone. [0016] As a spécifie example of the copolymerized polyester containing polyalkylene terephthalate as a main component, for example, there may be given copolymerized polyester containing polyethylene terephthalate as a main component, obtained by copolymerizing polyethylene terephthalate and one kind of a compound selected from the group consisting of ethylene glycol ether of bisphenol A, 1,4-çyclohexanedimethanol, isophthalic acid, and dihydroxyethyl 5-sodiumsulfoisophthalate.
[0017] The polyalkylene terephthalate and the copolymerized polyester containing polyalkylene terephthalate as a main component may be used alone or in combination of two or more kinds. It is preferred that, of those, copolymerized polyester containing polyethylene terephthalate, polyprepylene terephthalate, polybutylene terephthalate, or polyethylene terephthalate as a main component, obtained by copolymerizing polyethylene terephthalate, polyprepylene terephthalate, polybutylene terephthalate, or polyethylene terephthalate and ethylene glycol ether of bisphenol Al copolymerized polyester containing polyethylene terephthalate as a main component, obtained by copolymerizing polyethylene terephthalate and 1,4-çyclohexanedimethanol; copolymerized polyester containing polyethylene terephthalate as a main component, obtained by copolymerizing polyethylene terephthalate and isophthalic acid; and copolymerized polyester containing polyethylene terephthalate as a main component, obtained by copolymerizing polyethylene terephthalate and dihydroxyethyl 5-sodiumsulfoisophthalate be used alone or in combination of two or more kinds. [0018] Although no particular limitation is imposed on the intrinsic viscosity (IV value) of the polyester resin, the intrinsic viscosity is preferably 0.3 to 1.2, more preferably 0.4 to 1.0. When the intrinsic viscosity is 0.3 or more, the mechanical strength of fibers to be obtained does not decrease, and there is no risk of dripping during a combustion test. Further, when the intrinsic viscosity is 1.2 or less, the molecular weight does not increase excessively, and the melt viscosity does not become too high. Thus, melt spinning can be performed easily, and the fineness of fibers is likely to be uniform.
[0019] In the présent invention, as described above, the brominated epoxy flame retardant has the effect of reducing the gloss of the polyesterbased fiber for artificial hair to a level close to that of human hair and also has the effect of enhancing flame retardance.
[0020] Although no particular limitation is imposed on the brominated epoxy flame retardant, it is preferred that the brominated epoxy flame retardant be a compound represented by the following general formula (1). [0021]
o
(1) [0022] It should be noted that m is 1 to 1,000 in the above-mentioned general formula (1).
[0023] The brominated epoxy flame retardant is a compound represented by the general fonnula (1), and a weight-average molecular weight thereof is more preferably 2,000 to 40,000, still more preferably 5,000 to 30,000. In the présent invention, in order to reduce the gloss of the polyesterbased fiber for artificial hair, it is necessary that the molecular weight of the brominated epoxy flame retardant be high in libers. However, when the viscosity of the brominated epoxy flame retardant is high before being melt kneaded with the polyester resin, it becomes difficult for the brominated epoxy flame retardant to be dispersed uniformly in the polyester resin, and an aggregate of the brominated epoxy flame retardant, having a thickness of 10 pm or more is formed, which may cause breakage of a yarn and clegging of a nozzle during spinning. Therefore, it is preferred that the B component before being melt kneaded with the A component hâve viscosity equal to or lower than that of the A component that is a matrix. From the viewpoint of setting the viscosity of the B component to be equal to or lower than that of the A component, the weight-average molecular weight of the B component is preferably 2,000 to 40,000, more preferably 5,000 to 30,000. When the weight average molecular weight of the B component is 2,000 or more, a component having a molecular weight of 50,000 or more can be increased by 25% or more during melt kneading of the polyester resin composition, and hence the gloss is reduced sufficiently. Further, when the weight-average molecular weight of the B component is 40,000 or less, the B component does not aggregate in a non-uniform size to become more than 10 pm in the A component during kneading, and there is no risk in that the breakage of a yam or the dogging of a nozzle occurs to dégradé spinning stability.
[0024] In the présent invention, although the brominated epoxy flame retardant having a structure represented by the general formula (1) is preferably used as a raw material, the structure of the brominated epoxy flame relardant after melt kneading is not particularly limited. For example, an epoxy group, a hydroxyl group, phosphoric acid, or phosphonic acid may be substituted for the molecular end of the brominated epoxy flame retardant, or the molecular end of the brominated epoxy flame retardant may be bonded to the A component through an ester group.
[0025] The molecular weight ofthe brominated epoxy flame retardant increases during melt kneading due to the function of the acidic phosphorus-based compound that is the C component as a catalyst and/or a cross-linking agent. For example, there are the following cases: the molecular weight increases through ring opening and condensation reactions of epoxy groups between molécules of the B component; one molécule of the phosphorus-based compound of the C component and one to three molécules of the B component are condensed through an ester bond of a phosphoric acid group and an epoxy group to increase the molecular weight; the B component and the Acomponent are condensed through an ester bond; an epoxy group of the B component romains unreacted; and an epoxy group of the B component is ring opened to be présent as a hydroxyl group.
[0026] Specifïcally, in the polyesterbased fiber for artificial hair of the présent invention, the brominated epoxy flame retardant may be présent, for example, in a form (structure) represented by the following general formula (2).
[0027]
[0028] It should be noted that, in the general formula (2), m is 1 to 1,000; and Ri and
R2 are any one of functional groups represented by the following general formulae (3) to (10) and may or may not be identical with each other. Further, in the following general formulae (7) to (10), m is 1 to 1,000; and n is 1 to 200.

[0037] In the polyesterbased fiber for artificial hair of the présent invention, the brominated epoxy flame retardant may be présent with any of the above-mentioned structures. It is preferred that the brominated epoxy flame retardant be présent mostly in a structure with the acidic phosphorus-based compound of the C component being a cross-linking point, from the viewpoint of increasing the molecular weight of the B component. The bond between the acidic phosphorus-based compound of the C component and the B component can be confirmed, for example, as follows. The polyesterbased fiber for artificial hair is dissolved in a mixed solvent of hexafluoroisopropanol and chloroform, and an insoluble part is removed and dried. Then, the insoluble part is dissolved in chloroform again to obtain a soluble paît (B component). If the C component (phosphorus-based compound) remains in the soluble part, it can be determined that the C component has been bonded to the B component and is not eluted any more. In this analysis method, the content of the phosphorus-based compound in the B component is preferably 200 ppm or more, more preferably 300 ppm or more. Further, it is desired that the structure in which the B component is bonded to the A component through an ester bond be présent in a predetermined amount so as to prevent the B component from being peeled from the A component to form a void in the drawing step during spinning. When the ratio of the A component with respect to the B component is too high in the molécules in which the B component and the A component are bonded to each other through an ester group, the compatibility thcrcbctween increases excessively to make it difficult to increase an aggregate of the B component, and consequently, the effect of reducing the gloss may not be obtained sufficiently. The ro fore, it is preferred that the weight of the A component be less than 50% by weight of the B component in the molécules in which the B component and the A component aie bonded to each other through an ester group. In the case where the total weight of the B component and the A component is 100% by weight in the molécules in which the B component and the A component are bonded to each other through an ester group, the weight of the B component is more preferably 90% by weight or more, still more preferably 95% by weight or more.
[0038] In the polyester-based fiber for artificial hair of the présent invention, it is preferred that the ratio of a component having a molecular weight of 50,000 or more in the brominated epoxy flame retardant be 25% or more. In the présent invention, the ratio of the component having a molecular weight of 50,000 or more in the brominated epoxy flame retardant is measured as follows.
(1) 2 mL of a mixed solvent of hexafluoroisopropanol and chlorofoim (1:3) is added to 0.5 g of a sample, and the mixture is shaken at room température for 12 hours.
(2) 10 mL of a mixed solvent of hexafluoroisopropanol and chloroform (1:7) is added to the dissolved sample to dilute it, and the total amount of the mixture is transferred to an eggplant flask.
(3) The diluted solution of the sample is dried into a film shape by an evaporator and is further vacuum dried. 14 mL of chlorofoim is added to the obtained film-shaped sample, followed by ultrasonic extraction for 30 minutes, μ/ (4) The chloroform extract is separated.
(5) 7 mL of chloroform is further added to the eggplant flask, followed by ultrasonic extraction for 10 minutes.
(6) The chloroform extract is separated.
(7) The operations (5) and (6) are repeated 5 times.
(8) Ail the obtained chloroform extracts are mixed and filtered. After that, the molecular weights of the chloroform extracts were analyzed by a gel perméation chroniatography (GPC) measurement apparatus, and a ratio of a component having a molecular weight of 50,000 or more is determined based on the chart obtained by the GPC analysis.
[0039] In the polyesterbased fiber for artificial hair of the présent invention, the brominated epoxy flame retardant of the B component needs to be présent as an aggregate in the polyester resin of the A component so as to reduce the gloss of the polyesterbased fiber for artificial hair, and this effect is presumed to be expressed when the molecular weight of the B component is increased to enhance the viscosity. In the polyesterbased fiber for artificial hair of the présent invention, when the ratio of the component having a molecular weight of 50,000 or more in the B component is 25% or more, sufficiently high viscosity is obtained, and the gloss is easily reduced to a level close to that of human hair. Form the viewpoint of being excellent in the effect of reducing the gloss, in the polyesterbased fiber for aitificial hair of the présent invention, the ratio of the component having a molecular weight of 50,000 or more in the brominated epoxy flame retardant is 28% or more, more preferably 32% or more. It should be noted that, in the polyesterbased fibei· for artificial hair of the présent invention, it is appropriate that a predetermined amount of a polymer component is présent in order to increase the viscosity of the B component, and the weight’average molecular weight of the entire B component may be less than 30,000.
[0040] The polyester resin composition contains 5 to 40 parts by weight ofthe brominated epoxy flame retardant with respect to 100 parts by weight of the polyester resin. The polyester resin composition contains preferably 5 to 30 parts by weight, more preferably 6 to 25 parts by weight, still more preferably 7 to 20 parts by weight of the brominated epoxy flame retardant with respect to 100 parts by weight of the polyester resin. As long as the content of the brominated epoxy flame retardant is y/ within the above-mentioned range, the polyesterbased fiber for artificial hair can hâve gloss close to that of human hair, and is also excellent in flame retardance, combing properties, color development, and a spinnîng property.
[0041] In the présent invention, as described above, the acidic phosphorus-based compound of the C component is used as a catalyst and/or a cross-linking agent for increasing the molecular weight ofthe brominated epoxy flame retardant ofthe B component. For example, FIG. 1 shows molecular weight distributions obtained by conducting a GPC measurement of each brominated epoxy flame retardant in polyesterbased fibers in Example 2 containing stearyl acid phosphate (mixture of monostearyl phosphate and distearyl phosphate) as the C component and in the polyesterbased fibers in Comparative Example 1 not containing the C component. As is understood from FIG. 1, the component having a high molecular weight in the brominated epoxy flame retendant increases in the polyesterbased fibers in Example 2 containing an acidic phosphorus-based compound having a pH of 3.5 or less.
[0042] In the présent invention, when the C component has a pH of 3.5 or less, the C component has an activity for ring opening an epoxy group of the B component (hereinafter, simply referred to as “ring-opening activity”). From the viewpoint of being excellent in a ring-opening activity, the C component has a pH of preferably 3 or less, more preferably 2.5 or less, still more preferably 2 or less. When the C component has a pH of 3.5 or less, the C component has a high ring-opening activity. Therefore, the condensation reaction caused by the ring-opened epoxy group of the B component proceeds easily, and the molecular* weight of the B component tends to be sufficiently large, with the resuit that the effect of reducing the gloss can be obtained sufficiently. In the présent invention, the term “pH of 3.5 or less” means that the PH is 3.5 or less at room température (20 ± 5°C) and/or 28CTC. Further, in the présent invention, the pH is a value measured after 1 g of a measurement sample is dispersed in 10 g of pure water at prédéterminéd température. The acidic phosphorus-based compound has an activity of ring opening an epoxy group of the B component during melt kneading ofthe polyester resin composition when the acidic phosphorus-based compound has a pH of 3.5 or less at 28CTC even if it does not hâve a pH of 3.5 or less at room température. Further, in the case where the C component is not dissolved in water, the pH can be measured while powder of the C component is supplied to water va/' and dispersed therein by stirring.
[0043] No particular limitation is imposed on the C component, and it is appropriate that the C component is an acidic phosphorus-based compound having a pH of 3.5 or less. Examples of the C component include a monoalkyl phosphate ester, a monoaryl phosphate ester, a dialkyl phosphate ester, a diaryl phosphate ester, a monoalkyl phosphite ester, a monoaryl phosphite ester, a dialkyl phosphite ester, a diaryl phosphite ester, a monoalkyl phosphonate ester, a monoaryl phosphonate ester, alkyl phosphonate, aiyl phosphonate, a polyphosphonic acid compound, and a phosphoric acid métal sait. Of those, the phosphoric acid métal sait mostly has low acid strength in the case of an alkali métal, and for example, monosodium dihydrogen phosphate and disodium dihydrogen pyrophosphate are not suitable for the présent invention because they hâve insufficient acid strength due to a pH of more than 3.5. Specifically, examples of the C component include monomethyl phosphate, monoethyl phosphate, monoisopropyl phosphate, mono-n-butyl phosphate, isobutyl phosphate, mono(2-ethylhexyDphosphate, monolauryl phosphate, monosteaiyl phosphate, monooleyl phosphate, monotetracosyl phosphate, monophenyl phosphate, monocresyl phosphate, mono2,6-di-tert-butyl-4-methylphenoxy phosphate, dimethyl phosphate, diethyl phosphate, diisopropyl phosphate, di-n-butyl phosphate, dibutyl phosphate, di(2-ethylhexyl)phosphate, dilauryl phosphate, disteaiyl phosphate, dioleyl phosphate, ditetracosyl phosphate, diphenyl phosphate, dicresyl phosphate, monomethyl phosphite, monoethyl phosphite, monoisopropyl phosphite, mono-n-butyl phosphite, isobutyl phosphite, mono(2-ethylhexyl)phosphite, monolauryl phosphite, monostearyl phosphite, monooleyl phosphite, monotetracosyl phosphite, monophenyl phosphite, monociOsyl phosphite, dimethyl phosphite, diethyl phosphite, diisopropyl phosphite, di—n—butyl phosphite, dibutyl phosphite, di(2-ethylhexyDphosphite, dilauryl phosphite, distearyl phosphite, dioleyl phosphite, ditetracosyl phosphite, diphenyl phosphite, dicresyl phosphite, methyl phosphonate, ethyl phosphonate, isopropyl phosphonate, phosphonic acid-n-butyl, isobutyl phosphonate, phosphonic acid-2-ethylhexyl, lauiyl phosphonate, stearyl phosphonate, oleyl phosphonate, tetracosyl phosphonate, phenyl phosphonate, cresyl phosphonate,
1- hydroxyethane-l,l-diphosphonic acid, nitrilolris(methylenephosphonic acid),
2- phosphonobutane—1,2,4—tricarboxylic acid, Ν.Ν,Ν’,Ν’-ethylenediaminetetrakis (methylenephosphonic acid), monopotassium dihydrogen pyrophosphate, monomagnesium dihydrogen pyrophosphate, monozinc dihydrogen pyrophosphate, tripolyphosphoric acid, and monoaluminum dihydrogen tripolyphosphate. Of those, the C component is preferably one or more kind selected from the group consisting of phosphoric acid compounds having one or more hydroxyl group and phosphonic acid compounds having one or more hydroxyl group. In the case where the fiber of the présent invention contains an antimony compound or the case where the polyester resin of the A component is synthesized with an antimony catalyst, as described later, when the C component is a trivalent phosphorous acid compound, there is a risk in that antiomony is precipitated from the antiomony compound by a réduction reaction to color the fiber into gray color.
[0044] It is preferred that the C component hâve a molecular weight of200 or more. In the case where the molecular weight of the C component is 200 or more, when the polyester resin composition is melt kneaded, the C component is not gasified to be removed, and the substantial effective component of the C component is not reduce d, with the resuit that the gloss is unlikely to change. Further, it is preferred that the C component hâve an melting point of less than 280C or an average dispersion particle diameter of 2 pm or less. In this case, the melting point is measured by a differential scanningcalorimeter (DSC) or a differential thermal analyzer (DTA), and the average dispersion particle diameter refers to a médian diameter (d50) measured by a laser diffraction particle size analyzer. When the melting point is less than 280°C or the average dispersion particle diametei· is 2 pm or less, the contact area between the C component and the B component does not decrease to dégradé the reaction efficiency, and the molecular weight of the B component is likely to increase, and the sufficient effect of reducing the gloss is obtained easily. From the abovcmentioned viewpoint, it is preferred to use, as the C component, monolauryl phosphate, monostearyl phosphate, monooleyl phosphate, monotetracosyl phosphate, monophenyl phosphate, monocresyl phosphate, mono2,6--di--tert-butyl-4-methylphenoxy phosphate, di(2“ethylhexyl)phosphate, dilauryl phosphate, distearyl phosphate, dioleyl phosphate, ditetracosyl phosphate, diphenyl phosphate, dicresyl phosphate, lauryl phosphonate, steaxyl phosphonate, oleyl phosphonate, tetracosyl phosphonate, phenyl phosphonate, cresyl phosphonate, l-hydroxyethane-l,l-diphosphonic acid, nitrilotris (methylenephosphonic acid), 2-phosphonobutane-l,2,4—tricarboxylic acid,
N, N,N’,N’-ethylenediaminetetrakis(methylenephosphonic acid), monopotassium dihydrogen pyrophosphate, monomagnesium dihydrogen pyrophosphate, monozinc dihydrogen pyrophosphate, txipolyphosphoric acid, and monoaluminum dihydrogen tripolyphosphate. As the C component, the above-mentioned compounds may be used alone or in combination of two or more kinds.
[0045] The polyester resin composition contains 0.05 to 5 parts by weight of the acidic phosphorus*based compound having a pH of 3.5 or less with respect to 100 parts by weight of the polyester resin. The polyester resin composition contains preferably 0.1 to 2 parts by weight, more preferably 0.2 to 1.5 parts by weight, still more preferably
O. 4 to 1.5 parts by weight of the acidic phosphorus-based compound having a pH of 3.5 or less with respect to 100 parts by weight of the polyester resin. When the content of the acidic phosphorus-based compound having a pH of 3.5 or less is within the above-mentioned range, the gloss ofthe polyesterbased fiber for artificial hair can be rendered close to that of human hair, and is also excellent in flame retardance, color development, and a spinning preperty.
[0046] It is preferred that the polyester resin composition further contain 0 to 5 parts by weight of a thickener (hereinafter, also referred to as “D component”) with respect to 100 parts by weight of the polyester resin. In the polyester resin composition, the lower limit value of an addition amount of the thickener is more preferably 0.1 parts by weight, still more preferably 0.2 parts by weight, still further preferably 0.4 parts by weight, particularly preferably 0.8 parts by weight with respect to 100 parts by weight of the polyester resin. In the polyester resin composition, the upper limit value of an addition amount of the thickener is more preferably 4 parts by weight, still more preferably 3 parts by weight, still further preferably 2 parts by weight with respect o 100 parts by weight of the polyester resin. In the présent invention, the D component has the effect of increasing the viscosity of the polyester resin of the A component, and is used for further enhancing a spinning property, flame retardance, and combing properties.
[0047] It is preferred that the thickener be an organic compound having three or more at least one kind of a functional group selected from the group consisting of a hydroxyl group, an ester group, an epoxy group, and a carboxylic acid group in M/ molécules. Thus, when the D component has three or more functional groups (reaction points) in molécules, the transestérification between the A component and the D component proceeds during melt kneading, and the molécules of the polyester resin hâve a branched structure, which greatly increases the viscosity compared with ordinaiy straight-chain molécules. Examples of the thickener include glycérine, a glycérine fatty acid ester, a glycérine dibasic acid ester, a glycérine dibasic acid fatty acid ester, a glycérine phosphoric acid ester, erythritol, an erythritol fatty acid ester, an eiythritol dibasic acid ester, an erythritol dibasic acid fatty acid ester, an erythritol phosphoric acid ester, pentaerythritol, a pentaerythritol fatty acid ester, a pentaeiythritol dibasic acid ester, a pentaerythritol dibasic acid fatty acid ester, a pentaerythritol phosphoric acid ester, xylitol, a xylitol fatty acid ester, a xylitol dibasic acid ester, a xylitol dibasic acid fatty acid ester, a xylitol phosphoric acid ester, sorbitol, a sorbitol fatty acid ester, a sorbitol dibasic acid ester, a sorbitol dibasic acid fatty acid ester, a sorbitol phosphoric acid ester, sorbitan, a sorbitan fatty acid ester, a sorbitan dibasic acid ester, a sorbitan dibasic acid fatty acid ester, a sorbitan phosphoric acid ester, trimethylolpropane, malic acid, a malic acid ester, citric acid, a citric acid ester, tartaric acid, a tartaric acid ester, trimellitic acid, trimellitic anhydride, a trimellitic acid ester, a trimellitic anhydride ester, pyromellitic acid, pyromellitic anhydride, a pyromellitic acid ester, a pyromellitic anhydride ester, polyvinyl alcohol, a polyvinyl alcohol copolymer, polyacrylate, a polyacrylate copolymer, polyglycidyl méthacrylate, a polyglycidyl méthacrylate copolymer, triglycidyltriazine, and a polyepoxy resin. Of those, a polyhydric alcohol compound obtained by esterifying polyhydric alcohol with at least one kind of an acid component selected from the group consisting of carboxylic acid, phosphoric acid, and phosphonic acid is preferred. In the case where the D component is a polyhydric alcohol compound, the transestérification of the D component proceeds mainly with the A component, and hence the viscosity of the polyester resin can be increased efficiently. On the other hand, when the D component is polycarboxylic acid or a polyepoxycontaining compound, the reaction with the B component also proceeds, and mixed molécules of the A component and the B component increase. Therefore, the compatibility between the A component and the B component increases, and in some cases, the sufficient effect of reducing the gloss may not be obtained. Further, when the end of the D component is a hydroxyl group, the hydrolysis also proceeds in parallel with the branching of the A component molécules, and hence the viscosity may decrease. Therefore, the D component is preferably a polyhydric alcohol compound obtained by esterifying polyhydric alcohol with an acid component such as carboxylic acid, phosphoric acid, and phosphonic acid, more preferably a polyhydric alcohol compound obtained by esterifying polyhydric alcohol with phosphoric acid from the viewpoint that an ester bond portion cornes off easily during heating. More preferably, as the D component, a glycérine fatty acid ester, a glycérine phosphoric acid ester, a pentaerythritol fatty acid ester, a pentaerythritol dibasic acid fatty acid ester, a pentaerythritol phosphoric acid ester, pentaerythritol diphosphate, pentaerythritol diphosphite, dialkylpentaerythri toi diphosphate, dialkylpentaerythritol diphosphite, diarylpentaerythritol diphosphate, diarylpentaerythritol diphosphite, or a sorbitan fatty acid ester is used. As the pentaeiythritol diphosphite, for example, bis(2,6-di-tert-butyl-4-methylphenyl) pentaerythritol diphosphite or the like can be used, and as the pentaeiythritol dibasic acid fattyr acid ester, for example, pentaerythritol adipic acid stearic acid ester or the like can be used.
[0048] It is preferred that the polyester resin composition further contain 0 to 5 parts by weight of an antimony compound (hereinafter, also referred to as Έ component”) with respect to 100 parts by weight of the polyester resin. In the présent invention, the E component has the effect of further enhancing the flame retardance of the polyesterbased fîber for artificial hair, and is appropriately used in the case where it is necessary to enhance flame retardance.
[0049] No particular limitation is impose d on the antimony compound of the E component as long as the antimony compound is a compound having antimony atoms, and an antimony oxide is generally used due to the ease of handling as a powder material. Examples of the antimony compound include antimony trioxide, antimony tetraoxide, antimony pentoxide, and sodium antimonite. Those compounds may be used alone or in combination of two or more kinds. It should be noted that, there arise no problème even when the antimony compound of the E component reacts with a halogen element or a phosphorus element to change to another- compound during melt kneading. Further, from the viewpoints of a spinning property and color development, the E component preferably has a small particle diameter, and has an average particle diameter of preferably 5 pm or less, moiO preferably 2 pm or less. In this case, the average particle diameter lOfers to a médian diameter (d50) measured by a laser diffraction particle size analyzer.
[0050] The polyesterbased fiber for artificial haïr of the présent invention is obtained by melt spinning the polyester resin composition by an ordinaiy melt spinning method. The polyester resin composition can be obtained by dry blending each of the above-mentioned components, and melt kneading the mixture through use of various general kneaders. Examples of the kneaders include a single screw extrader, a twin screw extrader, a roll, a banbuiy mixer, and a kneader. Of those, the twin screw extrader is preferred from the viewpoint of the adjustment of a kneading degree and the ease of an operation.
[0051] In the case where the polyesterbased fiber for artificial hair of the présent invention is melt spun by an ordinary melt spinning method, for example, the températures of an extrader, a gear pump, a spinneret, and the like are set to 250 to 310°C, the polyester resin composition is melt spun to allow a spun y ara to pass through a heating pipe, the spun yam is cooled to a glass transition point or less of the polyester resin and taken up at a speed of 50 to 5,000 m/min., and thus the spun yarn (undrawn yam) is obtained. Altematively, the following is also possible^ the spun yam is cooled in a water tank containing water for cooling, and the fineness thereof is controlled. The température and length of the heating pipe, the température and spray amount of cooling air, the température of a cooling water tank, and the cooling time and take’up speed can be appropriately adjusted by the discharge amount of a polymer and the number of holes of the spinneret.
[0052] In the présent invention, it is preferred that the obtained spun yarn (undrawn yam) be hot drawn. The drawing may be performed any of a two-step method that involves drawing the spun yarn after taking it up temporarily, and a direct spinning drawing method that involves continuously drawing the spun yam without taking it up. The hot drawing is performed by a one-stage drawing method or a multi*stage drawing method of two or more stages. As heating means in the hot drawing. a heating relier, a heat plate, a steam jet device, a hot water tank, or the like can be used, and these heating means can also be used appropriately in combination.
[0053] As necessary, the polyesterbased fiber for artificial hair of the présent /q/ invention can contain various kinds of additives such as a flame retardant other than the B component, a heat-resistant agent, a photostabilizer, a fluorescer, an antioxidant, an antistatic agent, a pigment, a plasticizer, and a lubricant. By allowing the polyesterbased fiber for artificial hair to contain a pigment, spun-dyed fibers can be obtained. Further, the polyesterbased fiber for artificial hair can be rendered closer to human hair by adjusting touch and soft texture through use of an oil such as a fiber surface treatment agent and a softener.
[0054] It is preferred that the polyesterbased fiber for artificial hair of the présent invention be fibers in the form of non-crimped yam. Further, from the viewpoint of being suitable for artificial human hair, the fineness of the fiber is preferably 10 to 100 dtex, more preferably 20 to 90 dtex, still more preferably 35 to 80 dtex.
[0055] The polyesterbased fiber for artificial hair of the présent invention has gloss close to that of human hair, and also has satisfactory flame retardance, a spinning property, and color development. Further, it is preferred that the polyesterbased fibei* for artificial hair of the présent invention also hâve satisfactory combing properties. Further, the polyesterbased fiber for artificial hair ofthe présent invention is excellent in a curl setting property using a heat instrument for beauty treatment (hair iron, etc.), and is also excellent in a curl retentive property. Further, it is preferred that the polyesterbased fiber for artificial hair of the présent invention hâve heat résistance enabling a heat instrument for beauty treatment (hair iron, etc.) to be used at 160 to 24CFC, and be unlikely to ignite and hâve a self-extinguishing property. Further, by adding a dull additive if necessary, the unevenness can be provided to the fiber surface, and consequently, the gloss of the fiber can be appropriately suppressed so as to be used more suitably as artificial hair.
[0056] In the case where the polyesterbased fiber for artificial hair of the présent invention is spun-dyed, the fiber can be used as it is. However, in the case where the fiber is not spun-dyed, the fiber can be dyed under the same condition as that of ordinaiy polyester fibers. As a pigment, a dye, an assistant, and the like to be used for dying, those having weather résistance and flame retardance are preferred. [0057] The polyesterbased fiber for artificial hair of the présent invention can be directly used alone as artificial hair. Alternatively, the polyesterbased fiber for artificial hair of the présent invention can be used as artificial hair in combination with other fiber materials for artificial hair such as modacrylic fibers, polyvinyl chloride fibers, nylon fibers, and the like, and natural fibers such as human hair and animal hair.
[0058] A hair ornament product formed through use of the polyester-based fiber for artificial hair of the présent invention is excellent in gloss, flame retardance, and color development. Further, preferably, the hair ornament product has satisfactory combing properties. No particular limitation is imposed on the hair ornament piOduct, and examples thereof include a hair wig, a hairpiece, a weaving, a hair extension, braid hair, a hair accessory, and dole hair.
[0059] The hair ornament product may be formed only of the polyester-based fiber for artificial hair of the présent invention. Further, the hair ornament product may be formed by combining the polyester-based fiber for artificial hair of the présent invention with other fibers for artificial hair such as modacrylic fibers, polyvinyl chloride fibers, nylon fibers, and the like, and natural fibers such as human hair and animal hair.
[0060] Human hair to be used for a hair ornament product such as a hairpiece, a hair wig, or an hair extension is generally cuticle treated, decolorized, and dyed, and in order to ensure touch and combing properties, a silicone-based fiber surface treatment agent and a softener are used. Therefore, unlike untreated human hair, the human hair to be used for a hair ornament product has flammability. However, in the case where the polyester-based fiber for artificial hair of the présent invention is mixed with human hair, with a human hair mixed ratio being 60% or less, the résultant hair ornament product exhibits satisfactory flame résistance.

* Com. Ex.: Comparative Example [0078] As is apparent from Table 2, in the examples including the acidic phosphorus-based compound having a pH of 3.5 or less, polyesterbased fibers for artificial hair having gloss close to that of human hair and having satisfactory flame retardanœ (dripping résistance) and a spinning property were obtained. Further, in μ/'-'
Examples 5 to 8 using the thickener, it was confirmed that the combing properties, flame retardance (dripping résistance), and a spinningproperty are further enhanced. On the other hand, as is understood from the results of Table 3, in the comparative examples not including the acidic phosphorus-based compound having a pH of 3.5 or less and including the acidic phosphorus-based compound having a pH of more than
3.5, the polyesterbased fibers for artificial hair having gloss close to that of human hair were not obtained. Further, in Comparative Example 8 including the non-phosphorus acidic compound having a pH of 3.5 or less, spinning was not able to be performed. In the case of using a non-phosphorus acidic compound, the effect of 10 accelerating the décomposition of a polyester resin was very large compared with that of the acidic phosphorus-based compound, and hence the viscosity decreased greatly. Thus, a yarn was not able to be obtained normally during spinning.
Industrial Applicability [0079] According to the présent invention, a polyesterbased fiber for artificial hair and a hair omament product which hâve gloss close to that of human hair and which are excellent in color development, flame retardance (dripping résistance), and a spinning property can be provided.
