Description
FIBER BUNDLE FOR HAIR AND HAIR ORNAMENT PRODUCT
BACKGROUND OF THE INVENTION
1. Field of the Invention
The présent invention relates to a fiber bundle for hair capable of being used as an alternative to human hair and a hair ornament product that uses the fiber bundle for hair, Specifically, the présent invention relates to a fiber bundle for hair including a polyesterbased fiber and a polypropylene-based fiber as well as a hair ornament product that uses the fiber bundle for hair.
2. Description of Related Art
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 fîbers for artificial hair, instead of human hair, is increasing. As a fiber material for artificial hair, for example, synthetic fibers such as polyester-based fibers, polypropylene-based fibers, and polyamide-based fibers hâve been used. For example, JP H06-313213A discloses man-made hair including synthetic fibers such as a polyesterbased fiber and a polypropylene-based fiber. JP 2000-303239A discloses a hair weft including synthetic fibers such as a polypropylene-based fiber and a polyesterbased fiber.
SUMMARY OF THE INVENTION
However, synthetic fîbers such as polypropylene-based fibers and polyesterbased fibers hâve a high gloss in comparison with human hair, and furthermore hâve a hard texture and poor combing properties. Thus, when the synthetic fîbers are used for hair ornament products, particularly for hair products attached to human hair such as hair wigs and hairpieces, the whole hair looks unnatural due to the différence in gloss and texture between the human hair and the synthetic fîbers. In addition, in the case of the hair ornament products, the fibers are often curled using hair irons, and there is a demand for artificial hair having curling properties. Furthermore, in the case of the hair ornament products, hair ornament products having excellent voluminousness are favored.
In order to solve the above*described conventional problems, the present invention provides a fiber bundle for hair having a natural gloss and a soft texture that are similar to those of human hair and also having favorable combing properties, voluminousness, and curl holding properties as well as a hair ornament product.
The present invention relates to a fiber bundle for hair including a polyesterbased fiber and a polypropylene*based fiber, wherein the polyesterbased fiber contains 5 to 30 parts by weight of a brominated epoxy flame retardant with respect to 100 parts by weight of a polyester resin, the polyester resin being polyalkylene terephthalate and/or a copolymerized polyester containing polyalkylene terephthalate as the main component, and the fiber bundle for hair includes 10 to 90 parts by weight of the polyester-based fiber with respect to 100 parts by weight of the fiber bundle for hair.
In the fiber bundle for hair of the present invention, it is préférable that a fiber treating agent adhères to the polypropylene-based fiber, the fiber treating agent containing an acrylic resin and/or a colloïdal silica-containing silicone oil as well as an amino-modifîed silicone. It also is préférable that 0.1 to 1.5 parts by weight of the fiber treating agent adhères to the polypropylene-based fiber with respect to 100 parts by weight of the polypropylene-based fiber.
The present invention also relates to a hair ornament product including the above fiber bundle for hair.
According to the present invention, in the fiber bundle for hair including the polyester-based fiber and the polypropylene-based fiber, a spécifie polyester-based fiber is used, and the amount of that polyesterbased fiber included in the fiber bundle for hair is adjusted. Thus, the present invention can provide a fiber bundle for hair having a natural gloss and a soft texture that are similar to those of human hair and also having favorable combing properties, curl holding properties, and voluminousness as well as a hair ornament product.
DETAILED DESCRIPTION OFTHE INVENTION
The inventors of the present invention hâve conducted numerous studies to solve the above problems and found that when, in a fiber bundle for hair including a polyesterbased fiber and a polypropylene-based fiber, a polyester-based fiber containing 5 to 30 parts by weight of a brominated epoxy flame retardant with respect to 100 parts by weight of a polyester resin composed of polyalkylene terephthalate and/or a copolymerized polyester containing polyalkylene terephthalate as the main component is used as the polyesterbased fiber, and the fiber bundle for hair includes 10 to 90 parts by weight of the polyesterbased fiber with respect to 100 parts by weight of the fiber bundle for hair, the fiber bundle for hair has a natural gloss and a soft texture that are similar to those of human hair and also has favorable combing properties, curl holding properties, and voluminousness. Thus, the présent invention was accomplished. Moreover, the inventors of the présent invention also found that when a fiber treating agent containing an acrylic resin and/or a colloïdal silica-containing silicone oil as well as an amino-modified silicone adhères to the polypropylene'based fiber, the fiber bundle for hair has a natural gloss and a soft texture that are more similar to those of human hair and also has more favorable combing properties.
The polyesterbased fiber as used in the présent invention contains 5 to 30 parts by weight of a brominated epoxy flame retardant with respect to 100 parts by weight of a polyester resin. The lower limit of the content of the brominated epoxy flame retardant with respect to 100 parts by weight of the polyester resin is preferably 6 parts by weight or more, and more preferably 7 parts by weight or more. The upper limit of the content of the brominated epoxy flame retardant with respect to 100 parts by weight of the polyester resin is preferably 25 parts by weight or less, and more preferably 20 parts by weight or less. A brominated epoxy flame retardant content within the above-described range enables the gloss and texture ofthe polyester-based fiber to approximate to those ofthe human hair and also provides excellent combing properties and curl holding properties.
The polyester resin is composed of polyalkylene terephthalate and/or a copolymerized polyester containing polyalkylene terephthalate as the main component.
The polyalkylene terephthalate is not particularly limited and may be, for example, polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, or polycyclohexane dimethylene terephthalate. The copolymerized polyester containing polyalkylene terephthalate as the main component is not particularly limited and may be, for example, a copolymerized polyester containing polyalkylene terephthalate such as polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, or polycyclohexane dimethylene terephthalate as the main component and other copolymerizable components. In the présent invention, the term “main component” means a component that is contained in an amount of 50 mol% or more, Thus, the “copolymerized polyester containing polyalkylene teiOphthalate as the main component” refers to the copolymerized polyester containing 50 mol% or more of polyalkylene terephthalate. Preferably, the copolymerized polyester containing polyalkylene terephthalate as the main component contains 60 mol% or more, more preferably 70 mol% or more, and even more preferably 80 mol% or more of polyalkylene terephthalate.

The polyalkylene terephthalate and/or the copolymerized polyester containing polyalkylene terephthalate as the main component may be used alone or in a combination of two or more.
In the polyester-based fiber, the brominated epoxy flame retardant has the effect of causing the gloss and texture of the polyester-based fiber for artificial hair to approximate to those of human hair and providing a natural gloss and a soft texture that are similar to those ofhuman hair. From the standpoint ofcausing the gloss and texture of the polyesterbased fiber for artificial hair to approximate to those of the human hair, it is préférable that the brominated epoxy flame retardant is présent as aggregates in the fiber.
The brominated epoxy flame retardant may be any brominated epoxy flame retardant that causes the gloss and texture of the polyesterbased fiber for artificial hair to approximate to those of human hair, and is not particularly limited. For example, it is préférable to use as a raw material a brominated epoxy flame retardant having an epoxy group or tribromophenol at the end of the molécule.
The brominated epoxy flame retardant may be, but not limited to, for example, a compound including a structural formula represented by general formula (1) below in the molécule.
Chemical Formula 1
In general formula (1) above, m is 1 to 1000.
Specifically, the compound represented by general formula (1) above may be compounds that are represented by general formulae (2) to (4) below.
Chemical Formula 2
-'m
In general formulae (2) to (4) above, m is 1 to 1000, R1 is an alkyl group having 1 to 10 carbon atoms, and y is 0 to 5.
It is préférable that the polyester-based fiber further contains 0 to 5 parts by weight of an antimony compound with respect to 100 parts by weight of the polyester resin. Containing the antimony compound enhances the flame retardance of the polyesterbased fiber.
The antimony compound may be any antimony compound having antimony atoms and is not particularly limited. Examples of the antimony compound include antimony trioxide, antimony tetraoxide, antimony pentoxide, and sodium antimonate. Those compounds may be used alone or in a combination of two or more. The antimony compound may be a hydrate, and in the case where the antimony compound is a hydrate, it is préférable that the antimony compound content is 0 to 5 parts by weight with respect to 100 parts by weight of the polyester resin in terms of weight excluding the water of hydration.
The polyesterbased fiber is obtained by melt spinning a polyester resin composition containing the polyester resin, the brominated epoxy flame retardant, the antimony compound, and the like by an ordinary melt spinning method. The polyester resin composition can be obtained by dry blending each of the above-described components such as the polyester resin, the brominated epoxy flame retardant, and the antimony compound, and melt kneading the mixture using various general kneading machines. Examples of the kneading machines include a single-screw extruder, a twin-screw extrader, a roll, a Banbury mixer, and a kneader. In particular, the twin-screw extruder is preferred in terms of the adjustment of the degree of kneading and the ease of operation.
In the case where the polyesterbased fiber is produced by melt spinning by an ordinary melt spinning method, for example, the polyester resin composition is melt spun into yarns while the températures of an extrader, a gear pump, a spinneret, and the like are set to 250°C to 300°C. Then, the obtained yarns are cooled to a température of not more than the glass transition point of the polyester resin, and wound up at a speed of 50 m/min to 5000 m/min, and thus spun yarns (undrawn yarns) are obtained. Moreover, the spun yarns may be cooled in a water bath containing cooling water so as to control the fîneness. 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.
It is préférable that the obtained spun yarns (undrawn yarns) 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 yarns are once wound, and then drawn. In the direct drawing method, the spun yarns 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 a heating relier, a heat plate, a steam jet apparatus, or a hot water bath, and they can be used in combination as desired.
The polyesterbased fiber may contain various kinds of additives such as a flame retardant, a heat-resistant agent, a photostabilizer, a fluorescent agent, an antioxidant, an antistatic agent, a pigment, a plasticizer, and a lubricant as desired without impeding the effects of the présent invention.
The polypropylene-based fiber as used in the présent invention may be any polypropylene-based fiber that can be used as a fiber for hair, and is not particularly limited. A polypropylene resin that composes the polypropylene-based fiber is not particularly limited, and may be a homopolymer of propylene or may be a copolymer of propylene and other crolefins such as ethylene.
In the case where the polypropylene-based fiber is melt spun by an ordinary melt spinning method, for example, the polypropylene resin is melt spun into yarns while the températures of an extrader, a geai- pump, a spinneret, and the like are set to 200°C to 260°C. Then, the spun yarns are cooled to a température of not more than the glass transition point of the polypropylene resin, and wound up at a speed of m/min to 5000 m/min, and thus spun yams (undrawn yarns) are obtained. As in the case of the polyesterbased fiber, it is préférable that the obtained spun yarns (undrawn yams) are hot drawn.
Preferably, the above-described polyesterbased fiber and polypropylene-based fiber hâve a fineness of 10 to 100 dtex because the fineness within this range is suitable for artificial hair.

Preferably, 0.1 to 1.5 parts by weight of the fiber treating agent adhères to the polypropylene-based fiber with respect to 100 parts by weight of the polypropylene-based fiber. The lower limit ofthe amount ofadhesion ofthe fiber treating agent with respect to 100 parts by weight of the polypropylene-based fiber is more preferably 0.2 parts by weight or more, even more preferably 0.3 parts by weight or more, and still more preferably 0.4 parts by weight or more. The upper limit of the amount of adhesion of the fiber treating agent with respect to 100 parts by weight of the polypropylene-based fiber is more preferably 1.2 parts by weight or less, even more preferably 0.9 parts by weight or less, and still more preferably 0.8 parts by weight or less. An amount of adhesion ofthe fiber treating agent within the above-described range can provide favorable combing properties and also provide a soft texture and a natural gloss while preventing a significantly sticky texture. In the case where the fiber treating agent contains an acrylic resin, a colloïdal silica-containing silicone oil, and an amino-modified silicone, the weight ratio of the acrylic resin : the colloïdal silica-containing silicone oil : the amino-modified silicone is preferably 1:0.5 :0.5 to 1 : 3:10 and more preferably 1:1:1 to 1 · 2 :7, where the weight of the acrylic resin is taken as 1. In the case where the fiber treating agent contains an acrylic resin and an amino-modified silicone, the weight ratio of the acrylic resin : the amino-modified silicone is preferably 1:0.5 to 1:10 and more preferably 1:1 to 1 - 5, where the weight of the acrylic resin is taken as 1.

Adhesion of the fiber treating agent to the polypropylene-based fiber is not particularly limited and may be performed by, for example, immersing the polypropylene-based fiber in a treatment liquid containing the fiber treating agent. The treatment liquid containing the fiber treating agent may be obtained by dispersing or dissolving, preferably by dispersing, the fiber treating agent in an aqueous medium, The aqueous medium is preferably water, and, for example, distilled water, ion-exchanged water, ultrapure water, and the like may be used.

When necessaiy, one or more kinds of monomers selected from the group consisting of styrene, vinyl acetate, vinyl toluene, (meth)aciylic acid, crotonic acid, maleic acid, and fumaric acid may be added to the aciylic resin. The acrylic resin may be obtained by using the above-described monomers and performing émulsion (co)polymerization with a known method using a surfactant as an emulsifier or using polyvinyl alcohol (PVA) as a protective colloid.

21.5 cm, width: 1.5 cm). Then, an acrylic plate (10 g, length: 21.5 cm, width: 1.4 cm) was put as a weight on the fiber bundle.
(c) The height ofthe fiber bundle sandwiched between the acrylic plates was measured with a vemier caliper at three positions.
(d) The number (n) of the samples was set at 2, and an average value of the height of the fiber bundle at the total of six positions was taken as a bulkiness value of the fiber bundle.
(Combing Properties)
A fiber bundle (length: 32 cm, weight: 20 g) 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 fiber bundle down through it at a speed of 0.3 m/s. Thus, the ease of combing was evaluated.
A: The fiber bundle is combed with almost no résistance, and the combing properties are considerably favorable.
B: Although the fiber bundle is combed with a little résistance, the combing properties are favorable.
C: The fiber bundle is combed with a considérable résistance, or the comb is caught in the middle of the fiber bundle, and the combing properties are poor.
(Stickiness)
A: The stickiness is negligible, and the texture is équivalent to that of the human hair.
B: The stickiness is slightly higher than that of the human hair.
C: The stickiness is significant, and the texture is different from that of the human hair.
(Method for Measuring Amount of Fiber Treating Agent Adhe ring to Polypropylene-Based Fiber)
The amount of the fiber treating agents adhering to the polypropylene*based fiber was measured with a rapid residual fat extraction apparatus (model OC’l heater unit manufactured by Intec Co., Ltd.). Apolypropylene*based fiber to which a fiber treating agent adhered was eut to a fiber length of 12 to 15 cm, and about 2 g of the eut fiber was weighed out. The fiber was lightly kneaded and softened by hand, shaped into a cocoon-like shape, and placed in a dedicated test tube. This dedicated test tube was put in the rapid residual fat extraction apparatus. Then, 35 ml of a mixed solvent of éthanol and çyclohexane (weight ratio 1:1) was fed in the dedicated test tube, and an adjustment was made so that the mixed solvent drips at a rate of 1 to
1.5 drops per second. The solvent dripping from a lower portion of the dedicated test tube was received into a tray that was disposed on a table equipped with a heater. It should be noted the tray before receiving the solvent was weighed, and the weight at that time was taken as Wl. The heater was heated to about 80°C to volatilize the solvent. Even after the dripping of the solvent stopped, the tray was left for a while to volatilize the solvent in the tray. Furthermore, the tray was left in a dryer at 90°C for 5 minutes to completely volatilize the solvent. After that, the tray was taken out, cooled, and then weighed, and the weight at that time was taken as W2. Afterward, the amount of the fiber treating agent adhering to the fiber was calculated based on an équation below:
amount of adhesion of fiber treating agent(%omf) = {(W2 - Wl) / weight of fiber} x
100%.

As can be seen from the results shown in Thble 1, the fiber bundles for hair of Examples 1 to 6, each of which included the polypropylene-based fiber and the polyesterbased fiber containing the brominated epoxy flame retardant, had a natural gloss and a soft texture that were similar to those of the human hair and also had favorable combing properties, voluminousness, and curl holding properties.
As also can be seen from the results shown in Table 1, the fiber bundles for hair of Examples 1 to 6, each of which included the polypropylene-based fiber and the 10 polyester-based fiber containing the brominated epoxy flame retardant, were particularly superior to the fiber bundles for hair of Comparative Examples 1 and 4, each of which was composed only of the polyesterbased fiber, in terms of the voluminousness. Moreover, the fiber bundles for hair of Examples 1 to 6, each of which included the polypropylene-based fiber and the polyester-based fiber containing 15 the brominated epoxy flame retardant, were particularly superior to the fiber bundles for hair of Comparative Examples 2 and 3, each of which was composed only of the polypropylene-based fiber, in terms of the cui-l holding properties. Furthermore, the fiber bundles for hair of Exemples 1 to 6, each of which included the polypropylene-based fiber and the polyester-based fiber containing the brominated epoxy flame retardant, had superior combing properties and had a more natural gloss and a softer texture when compared with the fiber bundle for hair of Comparative Example 3, which was composed only of the polypropylene fiber, the fiber bundle for hair of Comparative Example 4, which was composed only of the polyester-based fiber that did not contain a brominated epoxy flame retardant, and the fiber bundle for hair of Comparative Example 5, which included the polyester-based fiber that did not contain a brominated epoxy flame retardant and the polypropylene-based fiber to which no fiber treating agent adhered.
