Description
POLYESTER-BASED FIBER FOR ARTIFICIAL HAÏR AND HAÏR ORNAMENT
PRODUCT INCLUDING THE SAME, AND
METHOD FOR PRODUCING THE SAME
Tbchnical Field [0001] The présent invention relates to a polyesterbased fiber for artificial hair that can be used as an alternative to human hair. Specifically, the présent invention relates to a polyesterbased fiber for artificial hair having a gloss and a texture that are similar to those of human hair, hair ornament products including the polyesterbased fiber for artificial hair, and a method for producing the polyesterbased fiber for artificial hair.
Background Art [0002] Conventionally, human hair has been used as a hair fiber material for hair ornament products such as hair wigs, hairpieces, hair extensions, hair accessories, and doll hair. In recent years, however, it becomes difficult to obtain the human hair. Therefore, the human hair has been supplanted by various artificial hair fibers including, e.g., an acrylic fiber such as a modacrylic fiber, a polyvinyl chloride fiber, and a polyesterbased fiber. The artificial hair fibers such as the polyesterbased fiber hâve a high gloss on the fiber surface. When the artificial hair fibers are used for hair ornament products, particularly for hair ornament products attached to the human hair such as hair wigs and hairpieces, the whole hair looks uncomfortable due to the différence in gloss between the human hair and the artificial hair fibers.
[0003] Thus, as a method for adjusting the gloss, Patent Document 1 proposes a technology for adjusting the gloss of a polyesterbased fiber for artificial hair by incorporating organic particles or inorganic particles into the polyesterbased fiber. This technology uses the fine particles to form projections on the fiber surface.
[0004] The artificial hair fibers are required to hâve a black based dark color, which is more similar to that of the human hair. However, the artificial hair fibers of a dark color tend to be too glossy because of the contrast différence with the reflected light. </
Therefore, the gloss of the artificial hair fibers needs to be reduced further.

Description of the Invention [0015] The présent inventors hâve conducted numerous studies to solve the above problème and found out that when a certain amount of a brominated epoxy flame retardant and a certain amount of an antimony oxide are incorporated into a polyesterbased fiber, the antimony oxide acts as a catalyst for the reaction of the brominated epoxy flame retardant, and the brominated epoxy flame retardant is formed into lumps (aggregates) with a predetermined size, so that the surface of the polyesterbased fiber for artificial hair is made uneven, and thus the gloss of the polyesterbased fiber can be suppressed and be close to the human hair, while a soft texture similar to the human hair is imparted to the polyesterbased fiber. As a îesult, the présent inventors hâve reached the présent invention.
[0016] The polyesterbased fibei’ for artificial hair of the présent invention is obtained by melt spinning a polyester resin composition. The polyester resin composition includes a polyester resin, a brominated epoxy flame retardant, and an antimony oxide.
[0017] The polyester resin is at least one kind of resin selected from the group consisting of polyalkylene terephthalate and a copolymerized polyester containing w/ polyalkylene terephthalate as the main component. The polyalkylene terephthalate is not particularly limited and may be, e.g., polyethylene terephthalate, polypropylene teiOphthalate, polybutylene terephthalate, or polycyclohexane dimethylene terephthalate. The copolymerized polyester’ containing polyalkylene terephthalate as the main component is not particularly limited and may be, e.g., a copolymerized polyester containing polyalkylene terephthalate (such as polyethylene terephthalate, polypropylene teiOphthalate, polybutylene terephthalate, or polycyclohexane dimethylene terephthalate) as the main component and other copolymerizable components. In the présent invention, the term “main component” means “containing the component in an amount of 80 mol% or more”. Thus, the “copolymerized polyester containing polyalkylene terephthalate as the main component” refers to the copolymerized polyester containing 80 mol% or more of polyalkylene terephthalate.
[0018] Examples of the other copolymerizable components include the following: polycarboxylic acids such as isophthahc acid, orthophthalic acid, naphthalenedicarboxylic acid, paraphenylenedicarboxylic acid, trimellitic acid, pyromellitic add, succinic acid, glutaric acid, adipic acid, suberic acid, azelaic acid, sebacic acid, and dodecanedioic acid, and their dérivatives; dicarboxylic acids including a sulfonic acid sait such as 5’sodiumsulfoisophthalic acid and dihydroxyethyl 5’sodiumsulfoisophthalate, and their dérivatives! 1,2-prepanediol; 1,3’prepanediol; 1,4-butanediol; 1,6'hexanediolî neopentyl glycol; 1,4-çyclohexanedimethanol; diethylene glycol! polyethylene glycol; trimethylolpropane; pentaeiythritoll 4‘hydroxybenzoic acid; c’caprolactone! and ethylene glycol ether of bisphenol A.
[0019] The spécifie examples of the copolymerized polyester containing polyalkylene terephthalate as the main component include a copolymerized polyester obtained by copolymerization of polyethylene terephthalate as the main component with one kind of compound selected from the group consisting of ethylene glycol ether of bisphenol A 1,4‘cyclohexanedimethanol, isophthahc acid, and dihydroxyethyl 5-sodiumsulfoisophthalate.
[0020] The polyalkylene terephthalate and the copolymerized polyester containing polyalkylene terephthalate as the main component may be used individually or in combinations of two or more. In particular, it is préférable that polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, a copolymerized polyester obtained by copolymerization of polyethylene terephthalate as the main component with ethylene glycol ether of bisphenol A a copolymerized polyester* obtained by copolymerization of polyethylene terephthalate as the main component with 1,4-çyclohexanedimethanol, a copolymerized polyester obtained by copolymerization of polyethylene terephthalate as the main component with isophthalic acid, and a copolymerized polyester obtained by copolymerization of polyethylene terephthalate as the main component with dihydroxyethyl 5-sodiumsulfoisophthalate are used individually or in combinations of two or more. [0021] The polyester resin composition includes 5 to 40 parts by weight of the brominated epoxy flame retardant with respect to 100 parts by weight ofthe polyester resin. The polyester resin composition includes preferably 10 to 30 parts by weight, and more preferably 15 to 25 parts by weight of the brominated epoxy flame retardant with respect to 100 parts by weight of the polyester resin. When the content of the brominated epoxy flame retardant is within the above ranges, the brominated epoxy flame retardant can react with each other by the action ofthe antimony oxide to form aggregates that are dispersed in the polyester resin in the form of islands, and thus an excellent effect of adjusting the gloss can be obtained.
[0022] The brominated epoxy flame retardant may use as a raw material a brominated epoxy flame retardant having an epoxy group or tnbromophcnol at the end ofthe molécule. The structure ofthe brominated epoxy flame retardant after melt kneading is not particularly limited and may hâve 80 mol% or more ofthe constitutional unit represented by the following chemical formula (1), where the total amount of the constitutional unit represented by the chemical formula (1) and another constitutional unit in which at least part of the chemical formula (1) is modified is 100 mol%. The structure of the brominated epoxy flame retardant at the end of the molécule may be changed after melt kneading. For example, the end of the molécule of the brominated epoxy flame retardant may be replaced by a hydroxyl group other than the epoxy group or tribromophenol, a phosphoric acid, a phosphonic acid, or the like. Alternatively, the end of the molécule of the brominated epoxy flame retardant may be bound to a polyester component through an ester group. Moreover, paît of the structure of the brominated epoxy flame retardant, except for the end of the molécule, μ/'- may be changed. For example, the brominated epoxy flame retardant may hâve a branched structure in which the secondaiy hydroxyl group and the epoxy group are bound. Also, part of the bromine of the chemîcal formula (1) may be eliminated or added, as long as the bromine content in the molécule of the brominated epoxy flame retardant is not changed significantly.
[0023] (fL^l) [0024] The brominated epoxy flame retardant is preferably a polymeric brominated epoxy flame retardant, e.g., as represented by the foliowing general formula (2). The polymeric brominated epoxy flame retardant represented by the general formula (2) may be a commercially available product such as a brominated epoxy flame retardant (trade name “SRT2MP’) manufacturée! by SAKAMOTO YAKUHIN KOGYO CO., LTD.
[0025] [0026] In the above general formula (2), m is 1 to 1000.
[0027] The polyester resin composition includes 1.5 parts by weight or more and less than 7 parts by weight of the antimony oxide with respect to 100 parts by weight of the polyester resin. When the content of the antimony oxide is within the above range, the antimony oxide readily acts as a catalyst for the reaction of the brominated epoxy flame retardant, and makes it easy for the brominated epoxy flame retardant to disperse in the polyester resin in the form of islands and to form an appropriate size and number ofaggregates, as will be described later. If the content ofthe antimony oxide is less than 1.5 parts by weight with respect to 100 parts by weight of the polyester resin, the brominated epoxy flame retardant is not likely to form aggregates that are dispersed in the polyester resin in the form of islands, as viewed in the cross section of the fiber parallel to the fiber axis direction. Therefore, it is difïïcult to obtain the effect of suppressing the gloss. On the other hand, if the content of the antimony oxide is 7 parts by weight or more with respect to 100 parts by weight of the polyester resin, the aggregates of the brominated epoxy flame retardant become too large, as viewed in the cross section of the fiber parallel to the fiber axis direction. Therefore, it is likely that the gloss is suppressed excessively, and the color development is reduced.
Thus, the résultant polyesterbased fiber looks much less natural than the human hair. Moreover, if the content of the antimony oxide is 7 parts by weight or more with respect to 100 parts by weight of the polyester resin, both the texture and the combing properties are poor. In view of the excellent effect of adjusting the gloss, the content of the antimony oxide is preferably 1.5 to 5 parts by weight, more preferably 1.5 to 4 parts by weight, and further preferably 1.5 to 3 parts by weight with respect to 100 parts by weight of the polyester resin.
[0028] Examples of the antimony oxide include antimony trioxide, antimony tetroxide, and antimony pentoxide. These antimony oxides may be used individually or in combinations of two or more. In the polyesterbased fiber for artificial hair, the brominated epoxy flame retardant and the antimony oxide hâve the effect of adjusting the gloss. In addition to the effect of adjusting the gloss, the brominated epoxy flame retardant and the antimony oxide may hâve the functions of a flame retardant and a flame retardant auxiliary, respectively. Moreover, the polyesterbased fiber for artificial hair may include other flame retardants other than the brominated epoxy flame retardant and other flame îOtardant auxiliaires other than the antimony oxide, as long as they do not interfère with the effects of the présent invention.
[0029] The other flame retardant auxiliaires may include métal antimonate. The métal antimonate is not particularly limited and may be, e.g., sodium antimonate or potassium antimonate. The other flame retardants may include, e.g., phosphorus-containing flame retardants and other bromine-containing flame retardants other than the brominated epoxy flame i*etardant. Examples of the phosphorus-containing flame retardants include a phosphoric ester amide compound and an organic cyclic phosphorus based compound. Examples of the other bromine-containing flame retardants include the following^ pentabromotoluene! hexabromobenzene! decabromodiphenyl! decabromodiphenyl ether! bis(tribromophenoxy)ethane; tetrabromophthalic anhydride! ethylene bis(tetrabromophthalimide); ethylene bisipentabromophenyD; octabromotrimethylphenylindan! bromine-containing phosphoric esters such as tris(tribiOmoneopentyl)phosphate! brominated polystyrènes! brominated polybenzyl acrylates! brominated phenoxy resin! brominated polycarbonate oligomers! tetrabromobisphenol A and tetrabromobisphenol A dérivatives such as ίο tetrabromobisphenol A-bis(2,3-dibromopropyl ether), tetrabromobisphenol A-bis(allylether), and tetrabromobisphenol A-bis(hydroxyethyl ether); bromine-containing triazine compounds such as tins(tribromophonoxy)triazine; and bromine-containing isocyanuric acid compounds such as tris(2J3-dibromopropyl)isocyamu‘ate. In particular, the phosphoric ester amide compound, the organic cyclic phosphorus based compound, and the brominated phenoxy resin flame retardant arc preferred because of their excellent flame retardançy.
[0030] In the polyesterbased fîber for artificial hair, the brominated epoxy flame retardant is formed into aggregates that are dispersed in the polyester resin in the form of islands.
[0031] It is préférable that the polyesterbased fiber for artificial hair has 50 or more aggregates of the brominated epoxy flame retardant, each aggregate having a length-to-width ratio of 2 to 20 and a diagonal width of 0.05 pm or more, per 360 pm2 in the cross section of the fiber parallel to the fîber axis direction. With this configuration, the surface of the polyesterbased fiber for artificial hair can be made uneven appropriately, and thus the gloss of the polyesterbased fîber can be adjusted to resemble the human hair, while a soft texture can be imparted to the polyesterbased fiber. Moreover, good combing properties also can be maintained. It is more préférable that the polyesterbased fiber for artificial hair has 40 or more aggregates of the brominated epoxy flame retardant, each aggregate having a length-to-width ratio of 2.5 to 100/7 and a diagonal width of 0.07 pm or more, per 360 pm2 in the cross section of the fiber parallel to the fiber axis direction. It is further préférable that the polyesterbased fiber for artificial hair has 10 or more aggregates of the biOminated epoxy flame retardant, each aggregate having a length-to-width ratio of 20/7 to 100/9 and a diagonal width of 0.09 pm or more, per 360 pm2 in the cross section of the fiber parallel to the fiber axis direction. In the above description, the length-to-width ratio of 2 to 20 corresponds to a flatness ratio of 0.05 to 0.5, the length-to-width ratio of 2.5 to 100/7 corresponds to a flatness ratio of 0.07 to 0.4, and the length-to-width ratio of 20/7 to 100/9 corresponds to a flatness ratio of 0.09 to 0.35.
[0032] It is préférable that the polyesterbased fiber for artificial hair has 300 or more aggregates of the brominated epoxy flame retardant, each aggregate having a diagonal width of 0.15 pm or more and less than 0.8 pm and a length-to-width ratio of more than 0 and less than 6, per 3036 pm2 in the cross section of the liber parallel to the fiber axis direction, and also has 20 or less aggregates of the brominated epoxy flame retardant, each aggregate having a diagonal width of 0.8 pm or more, per 3036 pm2 in the cross section of the fiber parallel to the fiber axis direction. With this configuration, the surface of the polyesterbased fiber for artificial hair can be made uneven appropriately, and thus the gloss of the polyesterbased fiber can be adjusted to resemble the human hair, while a soft texture can be imparted to the polyesterbased fiber. Moreover, good combing properties also can be maintained. It is more préférable that the polyesterbased fiber for artificial hair has 350 or more aggregates ofthe brominated epoxy flame retardant, each aggregate having a diagonal width of 0.15 pm or more and less than 0.8 pm and a length-to-width ratio of more than 0 and less than 6, per 3036 pm2 in the cross section of the fiber parallel to the fiber axis direction, and also has 15 or less aggregates of the brominated epoxy flame retardant, each aggregate having a diagonal width of 0.8 pm or moiO, per 3036 pm2 in the cross section of the fiber parallel to the fiber axis direction. It is further préférable that the polyesterbased fiber for artificial hair has 400 or more aggregates of the brominated epoxy flame retardant, each aggregate having a diagonal width of 0.15 pm or more and less than 0.8 pm and a length-to-width ratio of more than 0 and less than 6, per 3036 pm2 in the cross section of the fiber parallel to the fiber axis direction, and also has 10 or less aggregates of the brominated epoxy flame retardant, each aggregate having a diagonal width of 0.8 pm or more, per 3036 pm2 in the cross section ofthe fiber parallel to the fiber axis direction. If the number of aggregates of the brominated epoxy flame retardant with a diagonal width of 0.15 pm or more and less than 0.8 pm and a length-to-width ratio of more than 0 and less than 6 is less than 300, a sufficient effect of suppressing the gloss is not likely to be obtained. If the number of aggregates of the brominated epoxy flame retardant with a diagonal width of 0.8 pm or more is more than 20, there is a possibility that the gloss will be suppressed excessively, and the texture and the combing properties will be reduced.
[0033] In the présent invention, the diagonal width of an aggregate of the brominated epoxy flame retardant means the largest length of the aggregate in the direction perpendicular to the fiber axis direction, as viewed in the cross section of the fiber parallel to the fiber axis direction. In the présent invention, the maximum length of an aggregate of the brominated epoxy flame retardant, means the largest length of the aggregate in the direction parallel to the fiber axis direction, as viewed in the cross section of the fiber parallel to the fiber axis direction. In the présent invention, the length-to-width ratio of an aggregate of the brominated epoxy flame retardant means the ratio of the maximum length to the diagonal width ofthe aggregate. In this case, the ratio of the diagonal width to the maximum length of the aggregate of the brominated epoxy flame retardant indicates the flatness ratio. Hereinafter, a detailed explanation will be given based on FIG. 8 that schematically shows the diagonal width and the maximum length of aggregates of the brominated epoxy flame retardant in the cross section parallel to the fiber axis direction of the polyesterbased fiber for artificial hair of the présent invention. As shown in FIG. 8, the aggregates 20 of the brominated epoxy flame retardant arc dispersed in the polyester resin 10 in the form of islands, as viewed in the cross section 100 of the fiber parallel to the fiber axis direction D. In the cross section 100 of the fiber parallel to the fiber axis direction D, the largest length W of the aggregate 20 of the brominated epoxy flame retardant in the direction perpendicular to the fiber axis direction D is the diagonal width W, and the largest length L of the aggregate 20 of the brominated epoxy flame retardant in the direction parallel to the fiber axis direction D is the maximum length L. The length-to-width ratio of the aggregate 20 of the brominated epoxy' flame retardant is represented by the maximum length L / the diagonal width W. The flatness ratio of the aggregate 20 of the brominated epoxy flame retardant is represented by the diagonal width W / the maximum length L.
[0034] The aggregates of the brominated epoxy flame retardant in the polyesterbased fiber for artificial hair can be confirmed by observing the cross section of the fiber parallel to the fiber axis direction, e.g., with a scanning électron microscope (SEM). FIG. 1 shows an SEM photograph (5000X) of the cross section parallel to the fiber axis direction of the polyesterbased fiber for artificial hair in an example (Example 1) of the présent invention. In FIG. 1, the flat pièces dispersed in the polyester resin in the fonn of islands are aggregates of the brominated epoxy flame retardant. Moreover, in the présent invention, the SEM photograph of the cross section of the fiber parallel to the fiber axis direction can be used to measure the length-tœwidth ratio, the diagonal width, and the number of aggregates in a certain area of the aggregates of the brominated epoxy flame retardant. In the présent invention, the cross section of the fiber parallel to the fiber axis direction can be prepared, e.g., by cross section préparation (ion milling) using a cross section polisher (CP).
[0035] The polyesterbased fiber for artificial haïr may be colored, and preferably colored with a black-based dark color in view of the market demand. In the présent invention, the dark color means a color having an L value of less than 40 in the Lab color system (also simply referred to as “L value” in the following). The L value can be measured with a general colorimeter. Speeifically, e.g., a spectrocolorimeter CM-2600d manufactured by Konica Minolta, Inc. may be used. The polyesterbased fiber for artificial hair may be colored by dope dyeing or piece dyeing.
[0036] In the case of the dope dyeing, the polyester resin composition is prepared by melt kneading a coloring agent along with the components of the polyester resin composition such as the polyester resin and the brominated epoxy flame retardant, and the polyester resin composition including the coloring agent after melt kneading is then melt spun, thereby providing a dope dyed fiber. The coloring agent may be, e.g., a pigment or a dye. Examples of the pigment include a processed pigment that is treated with a dispersing agent or the like, and a masterbatch pigment. Examples of the dye include a processed dye that is treated with a dispersing agent or the like, and a masterbatch dye. These coloring agents may be used individually or in combinations of two or more.
[0037] It is préférable that the polyesterbased fiber for artificial hair includes 0.1 to 2 wt% of a pigment or a dye in the fiber. If the pigment or the dye is less than 0.1 wt%, the polyesterbased fiber is not colored sufficiently and may look dull in color. If the pigment or the dye is more than 2 wt%, the texture may be reduced. The concentration (content) ofthe pigment or the dye is preferably 0.1 to 2 wt%, and more preferably 0.3 to 1.5 wt% with respect to the polyester resin composition. If the concentration ofthe pigment or the dye is less than 0.1 wt%, the polyesterbased fiber is not colored sufficiently and may look dull in color. If the concentration of the pigment or the dye is more than 2 wt%, the texture may be reduced.
[0038] The pigment is not particularly limited, as long as it is used generally.
Examples of the pigment include organic pigments of black, yellow, red, brown, etc.
and inorganic pigments of black, yellow, red, brown, etc. The dye is not partîcularly limited, as long as it is used generally. Examples of the dye include organic dyes of black, yellow, red, brown, etc. and inorganic dyes of black, yellow, red, brown, etc.
Moreover, two or more types of pigments and dyes may be mixed and toned.
[0039] The spécifie examples of the pigment include carbon black, an anthraquinone'based pigment, and a peiînone'based pigment.
[0040] In the case of the piece dyeing, the polyesterbased fiber for artificial haïr can be dyed in the same manner as the dyeing process for dyeing a general polyesterbased fiber.
[0041] As the dye used for the piece dyeing, e.g., black, yellow, red, and brown dyes may be used as desired. Moreover, two or more types of dyes may be mixed and toned.
[0042] The spécifie examples of the dye include benzene azo-based (monoazo, disazo, etc.) disperse dyes, heterocyclic azo-based (thiazole azo, benzothiazole azo, thiophene azo, etc.) disperse dyes, anthraquinone-based disperse dyes, and condensate'based (quinophthalone, styryl, coumarfn, etc.) disperse dyes.
[0043] The dyeing is performed preferabiy at 90 to 150°C, and more preferabiy at 100 to 140°C. It is préférable that a dye bath containing the dye is adjusted to an appropriate pH.
[0044] In the piece dyeing, a dyeing assistant may be used with the dye in order to improve the fixability of the dye and the dispersibility of the dye. The dyeing assistant may be, e.g., a dispersing agent, a level dyeing agent, or an oligomer removing agent.
[0045] Specifically, examples of the dyeing assistant include the foilowing! a naphthalenesulfonic acid'formaldehyde condensation product; polyoxyalkylene alkylaryl ether; polyoxyalkylene alkyl ester! polyoxyalkylene alkylaryl ether sulfate ester sait; and polyoxyalkylene aryl ether sulfate ester sait. The dyeing assistant is used preferabiy in the range of 0.5 to 2 g/L with respect to the dye bath.
[0046] As a pH adjustor, e.g., a combination of acetic acid and sodium acetate, a combination of acetic acid and sodium pyrophosphate, or a combination of sodium dihydrogen phosphate or organophosphorus compound and polycarboxylic acid may be used. The pH adjustor is used preferably in the range of 0.5 to 2 g/L with respect to the dye bath.
[0047] It is préférable that the dye used for the piece dyeing is exhausted into the polyesterbased fiber for artificial hair in an amount of 0.1 mass% or more. The polyesterbased fiber for artificial hair has many color variations ranging from dark colors such as black haïr, neutral colors such as brown hair and red hair, to light colors such as blonde hair and white (gray) hair, Therefore, the amount of exhaustion of the dye needs to be adjusted appropriately in accordance with the color. The amount of exhaustion of the dye can be adjusted by the concentration of the dye bath, the dyeing température, and the dyeing time.
[0048] It is préférable that the pigment, the dye, the dying assistant, or the like used for coloring of the polyesterbased fiber for artificial hair hâve weathei· résistance and flame retardancy.
[0049] The polyesterbased fiber for artificial hair may include various additives such as a heat-resistant agent, a stabilizer, a fluorescent agent, an antioxidant, and an antistatic agent as needed. The stabilizer may be, e.g., stearyl acid phosphate.
[0050] The polyesterbased fiber for artificial hair of the présent invention can be produced by melt spinning the polyester resin composition to form aggregates of the brominated epoxy flame retardant that are dispersed in the polyester resin in the form of islands, as viewed in the cross section of the fiber parallel to the fiber axis direction. For example, the polyester· resin composition, which is obtained by dry blending the above components such as the polyester resin, the brominated epoxy flame retardant, and the antimony oxide, is melt kneaded using various general kneading machines, and then is formed into pellets. Subsequently, these pellets are melt spun so that the polyesterbased fiber for artificial hair can be produced. Examples of the kneading machines include a single*screw extrader, a twin-screw extrader, a roll, a Banbury mixer, and a kneader. In particular, the twin-screw extrader is preferred in tenus of the adjustment of the degree of kneading and the ease of operation.
[0051] The polyesterbased fiber for artificial hair- of the présent invention may be produced by melt spinning the polyester resin composition with a conventional melt spinning method. In such a case, e.g., the polyester resin composition is melt spun into yarns while the températures of an extrader, a gear pump, a spinneret, etc. are set to 250 to 300°C. Then, the spun yams (undrawn yams) are allowed to pass through a heated tube, cooled to a température of not more than the glass transition point of the polyester resin, and wound up at a speed of 50 to 5000 m/min. Moreover, the spun yams may be cooled in a water bath containing cooling water so as to control the fineness. The température and length of the heated tube, the température and amount of the cooling air applied, the température of the cooling water bath, the cooling time, and the winding speed can be adjusted appropriately in accordance with the extrusion rate of the polymer and the number of holes of the spinneret.
[0052] In the présent invention, it is préférable that the résultant spun yams (undrawn yams) are hot drawn. The drawing may be performed by either a two-step method or a direct drawing method. In the two-step method, the spun yams are once wound, and then drawn. In the direct drawing method, the spun yams are drawn continuously without winding. The hot drawing may be performed by a single-stage drawing method or a multi-stage drawing method that includes two or more stages. The heating means for the hot drawing may be, e.g., a heating relier, a heat plate, a steam jet apparatus, or a hot water bath, and they can be used in combination as desired.
[0053] Moreover, oils such as a fiber treatment agent and a softening agent may be added to the polyester-based fiber for artificial haïr, so that the texture and feel of the polyesterbased fiber can be doser to the human hair. The fiber treatment agent may be, e.g., a silicone-based fiber treatment agent or a non-silicone-based fiber treatment agent, which serve to improve the texture and the combing properties.
[0054] The fineness of the polyester-based fiber for artificial hair of the présent invention is preferably 10 to 100 dtex, and more preferably 20 to 90 dtex because the fineness within these ranges is suitable foi- artificial hair.
[0055] The polyesterbased fiber for artificial hair of the présent invention has a gloss and a soft texture that are similar to those of the human hair, and thus can be used suitably as artificial hair. Moreover, the color development and the combing properties are good. The polyesterbased fiber for artificial hair of the présent invention can be used as artificial hair either individually or in combination with other artificial hair fibers and naturel fibers such as human hair and animal hair.
[0056] The hair omament piOducts produced with the use of the polyesterbased fiber for artificial hair of the présent invention are characterized by an excellent gloss and texture. Moreover, the hair omament products also hâve excellent color development and combing properties. The hair omament products are not particularly limited and may include, e.g., hair wigs, hairpieces, weaving hair, hair extensions, braided hair, hair accessories, and doll hair.
[0057] The above hair omament products may be composed of only the polyesterbased fiber for artificial hair of the présent invention. Moreover, the hair omament products may be provided by combining the polyester-based fiber for artificial hair of the présent invention with other artificial hait' fîbers and nat ural fibers such as human hair or animal hair.

[0060] (Examples 1 to 2, Comparative Examples 1 to 2)
Each of the materials was dried to a moisture content of 100 ppm or less, and then the materials were dry blended in then* respective proportions, as shown in Table
1. The polyester resin composition thus obtained was supplied to a twin-screw extrader (trade name TEX44 manufacturedby Japan Steel Works, LTD.) and melt kneaded at a barrel température of270°C, and then was formed into pellets. The pellets were dried to a moisture content of 100 ppm or less. Next, the dried pellets were supplied to a melt spinning machine (trade name SV30 manufactured by SHINKOIND. LTD.), and a molten polymer was extruded through a spinneret with nozzle holes having a cocoon-shaped cross section (with an aspect ratio of 1.4 -1) at a barrel température of27(TC. The extruded polymer was aircooled with a cooling air at 2(FC and wound up at a speed of 100 m/min, thereby providing undrawn yarns. The résultant undrawn yams were drawn to 3.5 times using a heating roller at 75ÜC, heat’treated using the heating roller at ÎSCTC, and wound up at a speed of 30 m/min. Thus, a polyester-based fiber (multifilament) for artificial hair with a single fiber fineness of about 60 dtex was produced.
[0061] (Examples 3 to 5, Comparative Examples 3 to 6)
The materials were mixed in their lOspective proportions, as shown in Table 1, and the mixture was dried to a moisture content of 100 ppm or less. Then, the above pigments were added to the mixture and dry blended so that the total concentration (content) ofthe pigments was 0.7 wt%, and the weight ratio ofthe black pigment, the yellow pigment, and the red pigment was 60:25 :15. The polyester resin composition thus obtained was supplied to a twin-screw extrader (trade name TEX44 manufactured by Japan Steel Works, LTD.) and melt kneaded at a barrel température of 270°C, and then was formed into pellets. The pellets were dried to a moisture content of 100 ppm or less. Next, the dried pellets were supplied to a melt spinning machine (trade name SV30 manufactured by SHINKO IND. LTD.), and a molten polymer was extruded through a spinneret with nozzle holes having a cocoon-shaped cross section (with an aspect ratio of 1.4:1) at a barrel température of 270°C. The extruded polymer was aircooled with a cooling air at 20”C and wound up at a speed of 100 m/min, thereby providing undrawn yams. The résultant undrawn yams were drawn to 3.5 times using a heating roller at 75°C, heat-treated using the heating roller at 180C, and wound up at a speed of 30 m/min. Thus, a polyesterbased fiber (multifilament) for artificial hair with a single fiber fineness of tV about 65 dtex was produced.

[0064] (Example 8)
A polyesterbased fiber (multifilament) for artificial hair was produced in the same manner as Examples 3 to 5 and Comparative Examples 3 to 6, except that the mixture obtained by mixing the materials in their respective proportions, as shown in Table 1, was dried to a moisture content of 100 ppm or less, and then the above pigments were added to the mixture and diy blended so that the total content of the pigments was 0.02 wt%, and the weight ratio of the black pigment, the yellow pigment, and the red pigment was 10:80 · 10.
[0065] In the polyesterbased fîbers of Examples 1 to 8 and Comparative Examples 1 to 6, the diagonal width, the length-to-width ratio, the number of aggregates per 360 pm2 (standard 1), and the number of aggregates per 3036 pm2 (standard 2) of the aggregates of the brominated epoxy flame retardant in the cross section of the fiber parallel to the fiber axis direction were measured in the following manner, and the results of the measurement were shown in Table 1. Moreover, the gloss, color development, texture, and combing properties of the polyesterbased fibers of vS
Examples 1 to 8 and Comparative Examples 1 to 6 were evaluated in the following manner, and the results of the évaluation were shown in Table 1. With respect to the gloss, the colorless white fibers of Examples 1 to 2 and Comparative Examples 1 to 2 were evaluated based on the following gloss évaluation 1 using white Chïnese hair as a reference. The colored fibers of Examples 3 to 8 and Comparative Examples 3 to 6 were evaluated based on the following gloss évaluation 1 and gloss évaluation 2. First, the L values of black Chinese hair, chestnut Chinese hair, blonde Chinese hair, and white Chinese hair in the Lab color system were measured in the following manner, resulting in 15, 28,42, and 85, respectively. Then, the L values of the colored fibers of Examples 3 to 8 and Comparative Examples 3 to 6 were measured. In light of the above L values of the human hair, the fiber with an L value of less than 40 was evaluated based on the gloss évaluation 2 using the black Chinese hair as a reference, and the fiber with an L value of 40 or more was evaluated based on the gloss évaluation 1 using the white Chinese hair as a reference. The color development of Examples 3 to 8 and Comparative Examples 3 to 6 was evaluated in the following manner, and the results of the évaluation were shown in Table 1.
[0066] (Evaluation of aggregate of brominated epoxy flame retardant)
The diagonal width, the length-to-width ratio, and the number of aggregates in a certain area of the aggregates of the brominated epoxy flame retardant were observed and measured in the following analysis method. The préparation (ion milling) of the cross section of the fiber parallel to the fiber axis direction was performed using a cross section polisher (CP) (“SMO9020 CP’ manufactured by JEOL Ltd.) under the processing conditions of an accélération voltage of 6 kV. The morphological observation of the cross section of the fiber parallel to the fiber axis direction was carried out with a field émission scanning électron microscope (FE-SEM) (“ULTRA plus” manufactured by Cari Zeiss Co., Ltd.) at an accélération voltage of 2 kV. Since a composition image of a sample dépends on the average atomic number, the image becomes bright in a portion of the sample that includes heavy éléments and becomes dark in a portion of the sample that includes light éléments. In this example, the sample included the polyethylene terephthalate, the brominated epoxy flame retardant, and the antimony compound. Therefore, the order in which the bright composition image appeared was (1) antimony compound, (2) brominated epoxy flame u?
retardant, and (3) polyethylene terephthalate. For example, as shown in FIG. 1, the brominated epoxy flame retardant was found to be aggregates that were dispersed in the polyethylene terephthalate in the form of islands. Using the image analysis software (WinROOF available from Mitani Corporation), the diagonal width, length-to-width ratio, number of aggregates per 360 pm2 (standard 1), and number of aggregates per 3036 pm2 (standard 2) of the aggregates ofthe brominated epoxy flame retardant were measured from the image obtained. For the standard 1, the number of aggregates of the brominated epoxy flame retardant per 360 pm2 may be counted directly based on the image without using the image analysis software. However, the use ofthe image analysis software is prefeiTed because of its high accuracy.

i.e., a fiber surface treatment agent (trade name “Conditioner Tÿpe-Q” manufactured by MARUBISHI OIL CHEMICAL CO., LTD., molecular weight: 20000) and a cationic antistatic agent (trade name “Processing Oil No. 29” manufactured by MARUBISHI OIL CHEMICAL CO., LTD.) (with a weight ratio of 75 :25) so that 0.1 wt% ofthe PO/EO random copolymer and 0.1 wt% of the cationic antistatic agent were attached to the fiber. Then, the tow filament was dried at 80°C for 5 minutes. The tow filament thus treated was combed at least 30 times by running a comb made of a polyacetal resin (trade name “NEW DELRIN COMB No. 826” manufactured by Uehara Cell) from a point 3 cm below the top of the tow filament down through it at a speed of 0.3 m/s.

[0076] As can be seen from the results of Table 1, the polyesterbased fibers for artificial hair of the examples, in each of which the polyester resin composition including 100 parts by weight ofthe polyester resin, 5 to 40 parts by weight ofthe brominated epoxy flame retardant, and 1.5 parts by weight or more and less than 7 parts by weight of the antimony oxide was melt spun to form aggregates of the brominated epoxy flame retardant that were dispersed in the polyester resin in the form of islands, had a gloss and a texture that were similar to those of the human hair. Moreover, in the polyesterbased fibers for artificial hair of the examples, both the color development and the combing properties were good.
[0077] On the other hand, the polyesterbased fiber of Comparative Example 3 (FIG.
6) that did not include the antimony oxide and the polyesterbased fiber of Comparative Example 6 that did not include the brominated epoxy flame retardant did not hâve aggregates of the brominated epoxy flame retardant that were dispersed in the polyester resin in the form of islands, and thus significantly difiered from the human hair in gloss and texture. The polyesterbased fiber of Comparative Example 4 (FIG. 7) that included the sodium antimonate, but did not include the antimony oxide did not hâve aggregates ofthe brominated epoxy flame retardant that were dispersed in the polyester resin in the form of islands, and thus significantly diffeiOd from the human hair in gloss. In Comparative Example 1 that included less than 1.5 parts by weight of the antimony oxide, the gloss was significantly different from that of the human hair. In Comparative Examples 2 and 5 that included 7 parts by weight or more of the antimony oxide, both the gloss and the texture were significantly different from those of the human hair.
[0078] The polyesterbased fibers for artificial hair of Examples 1 to 8, in each of which the polyester resin composition including 100 parts by weight of the polyester resin, 5 to 40 parts by weight of the brominated epoxy flame retardant, and 1.5 parts by weight or more and less than 7 parts by weight of the antimony oxide was melt spun, had 50 or more aggregates of the brominated epoxy flame retardant, each aggregate having a length-to-width ratio of 2 to 20 and a diagonal width of 0.05 μιη or more, per 360 pm2 in the cross section of the fiber parallel to the fiber axis direction. Moreover, the polyesterbased fibers for artificial hair of Examples 1 to 8 had 40 or more aggregates of the brominated epoxy flame retardant, each aggregate having a length-to-width ratio of 2.5 to 100/7 and a diagonal width of 0.07 pm or more, per 360 pm2 in the cross section of the fiber parallel to the fiber axis direction. Further, the polyesterbased fibers for artificial hair of Examples 1 to 8 had 10 or more aggregates of the brominated epoxy flame retardant, each aggregate having a length-to-width ratio of 20/7 to 100/9 and a diagonal width of 0.09 pm or more, per 360 pm2 in the cross section of the fiber parallel to the fiber axis direction. Thus, the polyesterbased fibers for artificial hair of Examples 1 to 8 had a gloss similar to the human hair and a good texture.
[0079] The polyesterbased fibers for artificial hair of Examples 1 to 8 had 300 or more aggregates of the brominated epoxy flame retardant, each aggregate having a diagonal width of 0.15 pm or more and less than 0.8 pm and a lengtlrto-width ratio of more than 0 and less than 6, per 3036 pm2 in the cross section of the fiber parallel to the fiber axis direction, and also had 20 or less aggregates of the brominated epoxy flame retardant, each aggregate having a diagonal width of 0.8 pm or more, per 3036 pm2 in the cross section of the fiber parallel to the fiber axis direction. Thus, the polyesterbased fibers for artificial hair of Examples 1 to 8 had a gloss similar to the human hair and a good texture. In particular, when the polyesterbased fibers were colored with a dark color, they still had a gloss similar to the human hair and a good texture.
[0080] On the other hand, the polyesterbased fibers of Comparative Examples 1 to 6 had less than 50 aggregates of the brominated epoxy flame retardant, each aggregate having a length-to-width ratio of 2 to 20 and a diagonal width of 0.05 pm or more, per 360 pm2 in the cross section of the fiber parallel to the fiber axis direction. Moreover, the polyesterbased fibers of Comparative Examples 1 to 6 had less than 300 aggregates of the brominated epoxy flame retardant, each aggregate having a diagonal width of 0.15 pm or more and less than 0.8 pm and a length-to-width ratio of more than 0 and less than 6, per 3036 pm2 in the cross section of the fiber parallel to the fiber axis direction, or had more than 20 aggregates of the brominated epoxy flame retardant, each aggregate having a diagonal width of 0.8 pm or more, per 3036 pm2 in the cross section of the fiber parallel to the fiber axis direction. Thus, none of the comparative examples provided a polyesterbased fiber for artificial hair having aeloss
