Description

1353820 • Nine, invention description: [Technical field to which the invention pertains] %, the genus of the hair about the hair, that is, the artificial hair having the texture and physical properties similar to the natural hair, the wig and the artificial hair Manufacturing method. [Prior Art] In general, hair (ie, natural hair) has a diameter of about 8 〇 to 1 〇〇wm, and although it has natural curls or a roll due to a hair treatment, etc., it has a rain or When the shampoo is wet and the forest is wet, the curl will collapse and the elongation will occur. Further, it is known that the level of the degree of sizing also changes the texture property such as the moist feeling or the touch of the hair, or the physical property such as the bending rigidity. Therefore, the hair used in the wig is widely used since ancient times in order to make the ‘characteristics' similar to human natural hair as much as possible, because the natural hair taken from humans or animals is used as a material. However, in recent years, due to limitations in the supply of natural hair materials and other reasons, synthetic fibers have been used as hair styling materials for wigs, for example, synthetic fibers of polyacrylic, polyester, and polyamide. It is mostly used as a material for artificial hair. Since the artificial hair of the polyacrylic acid fiber has a low melting point and a poor heat resistance, the formability after perming is not good. For example, when it is exposed to warm water, processing such as curling of the fiber may be collapsed. weakness. In addition, the texture of the wet feeling or the touch is also different from that of the hair, and the straightness is weak and there is a sense of discomfort. On the other hand, although the polyester fiber is a material having good strength and heat resistance, it has extremely low hygroscopicity compared to natural hair, for example, at a height of 318951 5 1353820 • in a wet environment, it is different from natural hair. The appearance, touch, and physical properties of the wigs will be uncomfortable. When natural hair is exposed to moisture by rain or shampoo, the curl collapses and spreads out. However, since the polyester-based fiber has very low hygroscopicity and moisturizing power, it has a scaly which is rich in curl and maintains its growth, so that the elongation does not occur at all. Therefore, artificial hair is produced from polyester fibers, and after the hot-rolling treatment is temporarily performed, even if the humidity is changed, the curl imparted is not easily collapsed, and the behavior of the natural hair is not the same, and the unnatural feeling becomes conspicuous. As described above, the polyester-based fiber does not exhibit a change in the physical property value such as the texture or the curl holding force, such as the moist feeling or the touch, as the natural hair changes. Further, as with natural hair, a polyester fiber having a diameter of about 8 〇 to about #m is formed, and the bending rigidity value is too high compared to natural hair. The physical property value related to the texture of the fiber, such as the tactile sensation or the texture, is the force necessary for the % koji. It can be numerically converted into the fiber fabric industry by the Kawabata method. Cognitive physical property value (Non-Patent Document 1). There is also a device for measuring the bending rigidity value of one fiber or hair (Non-Patent Document 2). This bending rigidity value is called bending rigidity and is used for artificial hair. When a bending moment of a unit size is applied, it is defined by the reciprocal of the curvature change generated by the artificial hair. The larger the bending rigidity value of the artificial hair, the more resistant to bending and the more difficult to bend 'it is also said to be very hard and Conversely, the smaller the bending rigidity is, the easier it is to bend, and it can be said to be soft artificial hair. 匕/Using a polyether system having a diameter of about 80 to 1 〇〇am as with natural hair. When the fiber is used as artificial hair, its bending rigidity is higher than that of natural hair by 318951 6 1353820. When it is implanted on the wig base, it rises upwards. • The feel of the Japanese hair is high and the height is high. φ heart..., & compared to 蚪 'hard 梆梆 硬 ••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••• In the self-hairs of the self-hairs, the self-hairs of the clothes are used, and the hairs of the hairs are blended with the soft hairs of the body. The tendency to separate the hair is as follows. When the humidity is higher, the artificial hair made of the polystyrene fiber has a similarity to the above-mentioned iron hair than the artificial hair made of the polyacrylic acid or the polyacetate. Appearance and physical properties, in particular, according to the invention of the applicant by the surface treatment to remove the unnatural luster, it is possible to provide an excellent wig (see Patent Document 1). Among the polyamine-based fibers, the processing property of the aliphatic polyamine is particularly excellent. Therefore, it is suitable as artificial hair. However, the fiber made of aliphatic polyamine has a lower bending rigidity than natural hair, so even if the plant 5 is on the wig base, the erection is inferior and will follow. Wig base Therefore, the artificial hair made of aliphatic polyamine has a tendency to lack straightness and a sense of component. The result of intensive research by the applicant of this case, by using 爿B, the polyamine resin And the aromatic polyamine resin forms a sheath-core double structure, which can successfully produce artificial hair that exhibits a similar behavior as the natural hair that changes with the change of the humidity (Japanese Patent Application No. 2005, filed on February 15, 1997) -38415) According to this technique, the hair of the polyamide fiber can achieve the same bending rigidity value as the natural hair. In terms of other techniques related to artificial hair, it is also provided in order to make 7 318951 1353820 - such as a hair dryer (hair) Dryer) or curling iron (curling ir〇n), and artificial hair made of polyester fiber is mixed with artificial hair-bundle made of nylon fiber to make artificial hair bundle, and the number of artificial hair bundles is counted.

[Non-patent document 1] Kawabata Hiroshi, "Mechanical Society of Fiber Machinery, (Fiber Engineering)" 26, 10, ρρ. 721-728, 1973 [Non-Patent Document 2] KATO TECH, KES-SH Single hair bending tester operation manual * [Summary of the invention] [Problems to be solved by the invention] As described above, the artificial hair used in the wig is as close as possible to the day. The way of the touch (appearance, touch, texture) is applied in various ways. Further, it is desirable that the physical property values such as moisture absorption, tensile strength, elastic modulus, and bending rigidity are not inferior to those of natural hair, and it is preferable to have a physical property value superior to that of natural hair. The artificial hair composed of the scabbard core structure of the polyamido-based fiber of the present applicant has a diameter of about 80 to 100 which is about the same as that of natural hair as described above, and is constructed to be close to the texture of natural hair. So it is very good material. However, when the artificial hair composed of the polyamide fiber is attached to the wig base, the artificial hair has a plurality of characteristics which are adhered to each other and bundled over time. Therefore, each time Both must be carefully combed to comb the bundled hair. In addition, since the artificial hair of the polyamide fiber has the same hygroscopicity as the natural hair, when the humidity is high, the fibers are easily adhered to each other. The characteristics of the bundled state are formed. This tends to be 318951 9 1353820 when the humidity is higher. Therefore, when the awakening amine artificial hair is absorbed into the bundle, for example, when it is wet or shampooed, Wearing a wig wants to use a comb or a brush to comb. When the hair in the bundle state is used to organize the hair style, the artificial hair will also be difficult to disperse in a piece of L, and there will be a problem of time consuming when trying to obtain a desired hairstyle. This characteristic is also similar to the use of the artificial hair of the above-mentioned aliphatic and aromatic poly (four) wax to form a double core structure, it is difficult to suppress the bunching property of the artificial hair of the polyamine fiber, and the seat is higher. In the case where the artificial hair _ hairs are intimately connected to each other and bundled into a bundle or a strip shape, it is difficult to avoid the hairs of the polyester fibers made of polyester fibers. In the case of the wig base, although it is possible to prevent the bundles of the dragon fibers from each other, the nylon fibers are placed on the wig base in opposition to the natural hair. In contrast, the polyester artificial hair is incapable of being able to be combined with natural hair. Or the nylon fibers are well mixed, so the appearance of the knife is seen. This tendency is more obvious when the gas is higher, and the gas is more in the state: the nylon fibers are on the same scalp as the natural hair due to the relationship of the moisture absorption. However, because of the bending rigidity of the poly n fiber, the south is not easy to absorb moisture, so that it is erected upward, so that the king cannot feel natural and can easily be seen wearing a wig. The purpose of the project is to provide the touch and physical properties of the species and the natural ones. In particular, the part of the wig that is implanted on the base of the wig will be unnaturally plucked, and the hair style will be excellent. The same effect of the curling effect, there will be no artificial 318951 1353820 which is similar to the natural hair, and has the same feeling of rigidity as the natural hair. The hair, the wig using the artificial hair, and the method of producing the artificial hair. [Means for Solving the Problem] The inventors of the present invention have intensively studied and concluded that the bunching state of the polyamido-based artificial hair is due to the polyamine-based system. The relationship between the molecular structure of the artificial hair is likely to cause bundling, or due to the sub-binding force of the surface of the polyamine-based artificial hair, that is, the so-called van der Waals force. After various experiments, it is known that The polyamine-based artificial hair is used alone, and is mixed with artificial hair containing other synthetic fibers (specifically, polyethylene terephthalate), and then placed on the wig base to solve the bundle state. It is also known that in order to make the polyamido-based artificial hair have a bending rigidity value similar to that of natural hair, the fiber is formed into a double structure of the sheath and the core, and the ratio of the sheath core is adjusted to obtain very excellent characteristics, and in the case of polyparaphenylene. In the case of ethylene glycol diester-based artificial hair, knowledge of its diameter or melt spinning with other synthetic resins can be obtained, and the present invention has been completed. ♦ fibers of diterpene glycolate, in order to achieve the above object, the artificial hair of the present invention contains a pair of stupid and has the same degree of curvature as natural hair.

The stiffness value.

Am's range can have the same degree of curvature as natural hair

The relative stiffness of the piano. In this case, it is preferable that the present T-acid glycol ester and the composition have a range of 50 to 1 m from the natural hair which is perpendicular to the longitudinal direction of the fiber 318951. , when: 65 bending fibers of the bending value is ideally at a humidity of 4 ° • on the surface of the fiber ^ MM · G 々 range. Preferably, fine pores are formed in the longitudinal direction. According to the above configuration, by making the polyethylene terephthalate (4) Φ size the same as the natural hair S, the same degree of bending as the natural hair is the same as the natural hair: == For benzene, ethylene glycol grease and bending rigidity, and can be alcoholic vinegar, it can naturally adjust the bending rigidity of bending just connectable/eight/natural hair, so the color has similar shape to natural hair. The artificial hair of the characteristic is especially similar to: the artificial bending of the artificial hair is similar to that of the natural hair, and the texture of the appearance, the touch, the texture, etc., is similar to that of the natural hair, and the artificial hair is launched from the wig base. Temple: Shows the same movement of natural hair when erected from the scalp, so it can be realized and (4) is seen wearing a wig. When the surface of the artificial hair is in the length direction, there is a microscopic hole, and the light that is irradiated will be diffused. Therefore, the light can be suppressed and the gloss can be as high as that of the natural hair. The artificial hair bundle of the present invention is characterized in that 'the artificial hair composed of the polyester resin is dispersed to the second artificial hair composed of the polyamide resin. The mixture is mixed in a predetermined ratio to form a bundle, and the poly-resin resin contains polyethylene terephthalate, and the second artificial hair has a cross-sectional dimension and a bending rigidity value similar to those of natural hair. In the first artificial hair, it is preferred that the polyester resin contains polypair 318951 12 acetol and poly(p-butylene dicarboxylate si) and has the same bending rigidity value as the natural catalogue. 1 artificial hair length ^: the size of the j-face, the average diameter of the 5 〇 17 〇 quot 埋 上 上 上 上 上 上 上 上 上 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , 2鞠/core structure, and the core is composed of polyamine resin, which is composed of polyamide resin with lower rigidity than the core. The second artificial hair has natural and natural The same length of the length of the section 7 R 2 3 just 14 value ' and the humidity is 40%, the bending rigidity value is in the range of 6.5 to 7.8xl0 - 3gf.cmV. :: 1A made of polyester resin The working hair is appropriately mixed in the second artificial hair composed of the awakening amine resin, so that In the proper bundling property, the second artificial hair of the second artificial hair itself is made of polypyrene diammonium diacetate and polyparaphenylene terephthalate butyl vinegar, so Compared with the case of polyethylene terephthalate, it has the same bending strength value as natural hair, so it can provide a kind of appearance, touch, and the natural proximity of the shell and the natural hair. Artificial hair. A wig of the first structure of the heart and the arm, comprising a wig base and a planting in the hair, characterized in that: the artificial hair is made of poly-artificial hair composed of poly = lunar, and is composed of polyamide resin. The flag, the above-mentioned first person == stupid, " ▲, 曰 - has the same degree of cross-sectional dimensions as natural hair, that is, has the same degree of bending rigidity as natural hair. The wig of the second structure of the present invention comprises a wig base and is implanted in

318951 13 The artificial hair of the wig base is characterized in that: the artificial hair is a first artificial hair composed of a polyester, and a second artificial hair stylus composed of a polyamide resin, and the polyester resin is contained. The poly(p-citric acid) glycol and the polybutylene terephthalate are cool, and the first artificial hair has the same degree of bending rigidity as the natural hair. Preferably, the second artificial hair has a structure composed of a core portion and a sheath portion covering the core portion, and the core portion is composed of a permanent awakening amine tree, and the saddle portion is lower in bending rigidity than the core portion. Made of polyamine resin. By using the artificial hair of the above configuration in the wig of the present invention, it is possible to provide a wig which exhibits a natural loose feeling and which exhibits a behavior similar to that of natural hair. Therefore, since the i-th artificial hair system composed of the polyester resin and the second artificial hair composed of the polyamide fibers are appropriately mixed, the second artificial hair is bundled, and the hair style of the second artificial hair is not Poor occurrence, wig wear ^ show rhyme (10) naturally grows the appearance of its own hair, so it will not be found to wear a wig. The first constitution of the method is to obtain a polyethylene terephthalate (1) which has a wide bending rigidity value, and a polyparaphenylene group which is a material material, and a raw material for coloring is added, and the step of melting is carried out. 'The solidified filamentary melt is solidified, and the third bovine system extends the solidified filamentary material into a predetermined diameter/second artificial hair, and the characteristic bending rigidity value is , characterized by: the first step, which will be used as a shoulder material, poly 14 31895] ^ S ) 1353820 . P-benzoic acid glycol ester and poly-p-butylene dicarboxylate cool, and coloring raw materials The pre-twisted amount of shelling is smelted and set aside; in the second step, the extruded filamentous smelt is solidified; and in the third step, the solidified filamentary member is stretched into a shape In the first and second configurations, the first and second configurations may be subjected to a test for reducing the amount of fine pores formed on the surface of the artificial hair in any of the second step and the third step.

<According to the above configuration, the polyester resin can also provide artificial hair having the same characteristics as those of natural hair, and the artificial hair of the present invention can be mixed with the polyamide resin. In this case, artificial hair which can suppress the bundling of the artificial hair of the polyamine-containing resin can be provided. According to the present invention, it is possible to provide a polyester resin having a texture (appearance, a touch property, especially a bending rigidity value " 戍) and a work value, which is similar to a natural resin, which can suppress the artificial use of the poly-resin. The hair is bundled, so it is planted with polyamine tree, and the appropriate amount is used as the hair, whereby the heart and hair 1C are mixed with the hair-no...two constitutes the artificial friend's day cluster of the polyamide resin. In a bundle, they will be dispersed one by one. Accordingly, 3 the artificial hair of the polyamide wax can be loosened, and the same behavior as the virtual natural hair can be shown. Therefore, 纟"··, /, /, Fake MArn "In the wig according to the present invention, the burrs implanted on the base of the sputum are displayed with the wearer's own hair (four), so it is difficult to be found that the wig is worn and can exhibit a good appearance. Cow, you have gathered due to the past The artificial hair of vinegar tree wax has the artificial rigidity of the larger wig base from the wig base, and the bending rigidity value of the same artificial hair* is compared with that of the day.

318951 S 15 1353820 The erection of the artificial hair of the sap tree day is very obvious, and it is easy to see that it is impossible to achieve the uniformity of the hairstyle by wearing a fake friend. On the other hand, when the artificial hair of the resin is implanted on the base of the wig, the artificial hair of the resin is lower than the bending rigidity of the natural hair, and the state of lying down along the wig base is formed, so that the bending rigidity value of the hair is close to the sky. The shaft of the shaft resin is more obvious, and the hair from the European and the hair in the lying (four) will mix. As a result, it is easy to be seen = wearing fake 1C, and it is impossible to achieve the uniformity of the hairstyle. In contrast, according to the present invention

The artificial hair of the above-mentioned polystyrene resin is erected to the same extent as the natural hair, and is erected to the same extent as the burrs of the polyamide resin deposited on the wig base. As a result, it is difficult. It is seen that wearing a wig. [Embodiment] An embodiment of the present invention will be described in detail based on the drawings. First, the artificial hair of the present invention will be described. The artificial hair of the present invention is composed of a polyester-based synthetic fiber or a polyethylene terephthalate, and has a bending rigidity value similar to that of natural hair. Polyethylene terephthalate is a polymer obtained by polycondensing terephthalic acid with ethylene glycol. Further, the bending rigidity value of the same degree as the natural hair is 6.5 to 7.8 χ 10, ί · cm 2 / strip at a humidity of 4 〇 %, and 3.9 to 5.8 x 1 at a humidity of 8 〇 % ( T3gf · cmV / strip. Artificial hair composed of polyester fibers is dispersed to artificial hair composed of polyamide fibers, and artificial hair composed of polyamide fibers is inhibited when planted on a wig base at a predetermined ratio The bundling property, and because the artificial hair of the polyester fiber has the same bending rigidity value as the artificial hair and natural hair of the polyamide fiber, it can be 318951 16 1353820, and does not come out from the head of the wig. The same action of the artificial bran of the gluten-free base of the gluten-based base:: 植=wig wig wig-based polyamine-based artificial hair: 'with the planting of the main ginseng from the ▲ E text The scalp of the wigs of the cockroach grows out of the sky..., the appearance of the sables is the same, and the appearance of the genitals is the same. =: The embodiments of the artificial hair according to the present invention are described. - The first form of the alcohol hair is Containing polyethylene terephthalate == as needed The fiber of the material, the fiber has the same degree of ridge curvature, and has a pattern of the polyethylene terephthalate of the present invention as the bismuth hair of the natural hair. Artificial hair 1 is as shown in Fig. 1, ;: open: can be circular, or can be flat in any direction, or open: the second aspect of the invention; / is 50 to 7Mm ° because the average diameter of the section of artificial hair 1 is not (four), the bending stiffness value is lower than that of natural hair, and when implanted on the wig base, the wig base is in a state of lying down, so it is not ideal. When the average force of the anti-ground force is more than 7 ,, the bending rigidity value is too higher than the day... When the hair is implanted on the wig base, it is not preferable from the abundance of the wig base. The second form of the artificial hair of the present invention It is composed of a polyester-based synthetic fiber, and the composition of the lysine-based synthetic fiber contains polyglycol-methyl ethoxylate and polybutylene terephthalate in a predetermined ratio, and has a enthalpy Gross f - degree of bending stiffness value. Polybutylene terephthalate ^ In essence, it will be obtained by polycondensation of stearic acid and i,4-butanediol to obtain 318951 1353820, and by poly(p-diacetate) and polybutylene terephthalate. The fiber constituting 'haves a diameter substantially the same as that of the natural hair, and the bending rigidity value is close to that of the gluten. The appearance, the touch, and the quality of the temperament are two, "Bei is in the form of the above-mentioned brothers 1 to 3. Artificial hair (hereinafter referred to as "first artificial hair") is attached to the wig base so as to be mixed with the artificial hair of the amnesium-based fiber structure, whereby the 帛! and the second = strip are dispersed and loosened. Therefore, it is possible to suppress the second person's sex. When combing into a desired hairstyle, it is possible to prevent the unnatural phenomenon caused by the bundle and the wig, and the wig can be made to have a natural appearance. 1〇. • The work hair pattern represents a diagram of the human jade hair bundle iq of the present invention. The human i-artificial hair / wide 3 picture shows the 'multiple strips made up of synthetic polyester fibers = the = after the construction of the disperse amine synthetic fiber' - while making this 苐 and 2: 2 :: bundled, then, bottom, - edge randomly planted. The second embodiment is suitably dispersed in the wig base fiber and has a poly-based value of 2 with the natural hair. Cross-sectional dimension and bending rigidity of the branch phase (10) degrees In the artificial hair bundle, the thermal contraction rate of the 2 1 At ^ Μ 1 , the artificial hair 5 is the same as that of the first artificial hair i. According to this configuration, when the artificial hair walks ln per AU, the heat is processed by the second artificial main t yoke, and the second artificial main t yoke heat is processed, and the same degree of shrinkage can be produced by the anti-twisting t: two. When the second artificial hair 5 is heat-shrinked;:: the first production = factor is as follows. When the artificial hair 1 of the door 1 is applied to the 318951 19 'δζυ artificial hair bundle 10, the i-th artificial hair adjacent to the second artificial hair is contracted in the same manner as the second artificial hair 5. However, since the contraction of the second artificial hair 5 is larger than the contraction of the IA hair 1, the contraction of the third artificial hair is small, or slack, and the predetermined beautiful curl cannot be formed, and the ridge forms a wavy portion. Fig. 4 is a view showing a preferred configuration of the second artificial hair 5 shown in Fig. 3, (A) is a perspective view, and (B) is a vertical sectional view of the second artificial hair 5 in the longitudinal direction. As shown in the figure, the second artificial hair 5 has a sheath/a structure having a sheath portion 5A on its surface and a core portion 5B inside the portion 5A, and is composed of a polyamide resin. Although the sheath/core structure is shown as being arranged in a substantially concentric shape, the core portion 5 B and the portion 5A may have a substantially conical shape other than the concentric shape, and the second artificial hair 5 may be used. The cross section can also be circular, elliptical, eyebrow or the like. The polyamide resin which is a material of the core portion 5B is preferably a semi-aromatic polyamide resin having high strength and rigidity, and may be exemplified by 1,6 of the formula 1: a polymer composed of an amine (a copolymer of hexamethy 16116 (^3111丨116) and terephthalic acid (for example, nylon 6T), or adipic acid and isophthalonitrile diamine represented by Chemical Formula 2 A polymer (e.g., nylon MXD6) which is bonded by a combination of guanamine, etc. The polymer material represented by Chemical Formula 2 is easier to perform hair set than the polymer material represented by Chemical Formula 1. Further, 'Nylon' is a registered trademark of DuPont.

The formation of the spherulites and/or the processing of the spheroidal crystals are as follows: as long as it is larger than the wavelength of the visible light, the concave and convex portions are formed. 2. The artificial hairs 5 and 6 can also be used according to the wearing color. The coloring can also be blended with human pigments and human money in the kneading of the poly-elements as the raw material of the spinning material, or can be dyed after spinning. The second human hair 5, 6 series is used in the material 5 Flexing the rigid south polyamide, using the saddle/heart structure & '' of the polyamine which bends less rigid than the core 5β in the sheath 5', can change the stiffness according to temperature or humidity, and can be used to display the approximate natural hair movement Artificial hair. The mixing ratio of the first artificial hairs 1, 2 and the second artificial hairs 5, 6 of the artificial hair bundle 10 is preferably in the range of 1 〇 to 6 〇 by weight, particularly eight, at 20 to 30% by weight. Right and left is appropriate. Because polyamine fibers are not bundled in this desirable range. When the mixing ratio of the first artificial hair and 2 (i.e., polyester fiber, quasi-) is less than 5% by weight, the polyamide fibers are aggregated, which is less desirable. On the other hand, when the mixing ratio of the polyester fiber (the third artificial hair) exceeds 60% by weight, the polyamide fiber is not bundled, and the polyester fiber (the third artificial hair) is conspicuous. not ideal. This is because the polyester fiber is inferior in hygroscopicity to the polyamide fiber, and therefore the artificial hair bundle 1 composed of the two fibers exhibits different actions due to the difference in hygroscopicity and the change in humidity. 22 318951 I353820 As described above, in the case of polyamine-based human hair, it becomes difficult to assemble, and in the work hair, the mixed polyester-based artificial hair has a different chemical structure and is used in polyamine-based artificial hair. The hair is easy to be positively charged and gathered in the preparation. The ash and polyamines are artificially artificial because of the artificial hair bundle; the hair is easily negatively charged. Work hair 5, "better weight:: 1st artificial hair 2 and 2nd person 5, 6 will not be bundled, and the third is composed, so the 2nd artificial hair 5, 6 can have and the day #毛毛We, 2, and 2 artificial hair... and the same degree of bending rigidity of the hair. Next, the wig of the present invention will be described. Fig. 6 is a schematic representation of the squint of the wig 20, which uses the artificial vehicle 1 of the present invention. The bottom wig 20 of the first person m is attached to the wig base 11 1 artificial hair fc and second artificial hair 5, the proportion of planting. The third person preliminarily ^ t ^ artificial hair 丨, 2 is composed of poly-anthraquinone synthetic fibers as described above, and #1 八 兴 天然 天然 natural hair with the same degree of rigidity. The second artificial hair R is generally composed of t-branched synthetic fibers, and has the same cross-sectional dimension and bending rigidity as the natural hair. As described above, it is preferable that the core is composed of a core. 5β is a highly rigid guanamine resin' and _A is composed of a polyamine resin having a lower rigidity than the core 5B. The mixing ratio of the first artificial hairs 1 and 2 and the second artificial hairs 5 and 6 implanted on the wig base 21 is such that the first artificial hairs 1 and 2 are mixed at about 20 ± 5% by weight in any region. It is better. This is because when the mixture is mixed in the preferred range, the second artificial hairs 5, 6 which are constructed by the polyamide fibers of the wig base 21 are not bundled. When the first! When artificial hair is mixed 318951 23 l353820 When the proportion is less than 20 ± 5% by weight, the polyamide fibers are bundled, which is less desirable. On the other hand, when the mixing ratio of the polyester-based fibers (first artificial hair) exceeds 20 ± 5% by weight, although the polyamide fibers are not bundled, the polyester fibers (different artificial hair) are more conspicuous. not ideal. The wig base 21 may be composed of a mesh substrate or an artificial skin substrate. As shown in the figure, the wig base 21 is composed of a mesh member, and the second artificial hair 2 and the second artificial hair 5' 6 are planted in a vertical and horizontal filament constituting the mesh member.

Next, the method for producing the artificial hair of the present invention will be described. First, the device system used in the method for producing artificial hair of the present invention will be described. Fig. 8 is a view showing the artificial method of the present invention. A schematic diagram of a vibration system used for the production of hair. As shown in Fig. 8, the manufacturing apparatus 3 includes a particle 〇(1)(4) in which a polyethylene terephthalate resin as a raw material is previously placed, or contains a coloring. A raw material tank 31 of pellets of a raw material polyethylene terephthalate resin; a melt extruder 32 which melts and kneads the raw material; and a melt which is kneaded by the melt extruder 32 is extruded from the extrusion port 32A. The filamentary melt is cured by the warm bath portion 33; then, the artificial hair is wound by a three-stage extension heat treatment step of each of the extension rollers 34, %, 38, 40 and the dry heat grooves 35, 37, 39. Winding machine 41; and used in The surface of the wire is further formed by an alkali reducing portion (not shown) of the fine pores 2a. The smelting and scrambler 3 2 has a pellet of a polyethylene terephthalate resin as a raw material or contains a polybutylene 318951 25 1353820 coloring raw material, a heating device for melting the particles of the acid B-known resin, a kneading device for dispersing and mixing, and a gear for conveying the molten metal to the dial 32 Α Pump (gear puinp) The extrusion port 32A of the extruding portion 32 is provided with a predetermined number of predetermined diameters. The fiber system extruded from the extrusion port 32A of the extrusion portion 32 is as shown in the drawing, and the temperature is 33: the first extension roller 34 The first dry heat tank %, the dry 39 rolling IT, the second dry heat tank, the third extension drum 38, and the third *丨田: After stretching the drum 40, the winding machine 4 is wound up after the winding machine 4: As for the 4th part of the wide 'illustration', the alkali reduction treatment is carried out. The first extension roller. First, = , : the speed of the cylinder relative to the first extension: the speed of the drum with f increases 'by the ith extension of the wire member, and then, the roller drum 3 of the third extension roller 38 is increased in speed By the second gas phase for the extension of the second phase, after the autumn, the third extension of the second extension of the human body member (tension^r^#^, ^ 乂 和 yoke added to the tension of the fiber (fn) to cut the size The stable loose-stretching treatment stretch drum 40 is connected between the winder 41, and may also have (4) a lingling device (not shown). The main oil 苐9 image is a description of the reducing portion 4 5 4 θ Λη AC , 士,式图. The reduction and reduction section 45俜 contains. The liquid storage part 46, the deposit contains the water test; the reading place

47, in which the portion of __ is partially impregnated, and the W-type suspension fiber 100 is rotated; and the upper portion of the square tubular portion 47 of the spray-storage portion 46 is placed in the rotation of the suspension. The fiber 100 of the same portion 47 is sprayed at 318951 26 1353820 to form a liquid. The liquid storage unit 46 stores the aqueous solution containing the alkali solution and the actin-promoting liquid for promoting the hydrolysis, and the part of the fiber (10) is immersed in the treatment direction of the treatment, and the portion 47 is a three-pair tube. The portion that is extended on the rotating shaft is 4 and the main portion has a substantially triangular cross-sectional shape, and each of the tubes is provided with a plurality of shots on the opposite side of the direction of the rotation axis. A'彳 will flow into the tube portion. The treatment liquid is sprayed in the outer direction of the rotation to the inner portion 45, and the fiber can be treated by stretching and relaxing the fiber 100 Å, that is, by immersing the portion of the fiber 100 in the treatment liquid, the fiber can be made the same. The ground cover (4) makes the fiber diameter smaller. The dream is rotated in the direction indicated by the head, and the rotary cylinder portion 47 is rotated, and (4) the rotation direction is shown in the direction indicated by the line in Fig. 47. At this time, each jet from the rotary 2 The processing liquid sprayed from the port 47a or the shower portion 48 is: on the outer peripheral surface of the fiber (10) suspended from the rotating tubular portion 47. On the right side of the rotation of the 卩47, the moving direction of the fiber 1〇〇 (shown by the solid line) The direction of the arrow) and the direction of movement of the processing liquid itself (dotted line The arrow = "to" is consistent, and along the direction of movement of the fiber (ie, the solid yoke etching process along the flow of the treatment liquid. On the other hand, due to the left side of the rotating cylinder 47, the movement direction and processing of the dimension 100 The direction of the liquid is reversed, so it will be reversed in the direction of the 'private movement. As mentioned above, the 4 fluid attached to the fiber 10 0 = surface will be from the surface of the fiber due to the weight of the treatment liquid: fiber The axial direction (ie, the length direction) flows downward and downward, and the etching process is performed in a manner along the L-direction. In this way, the fiber 100 can be borrowed from 318951 27 1353820 and can be shaped in the axial direction of the fiber. It is made finer into fine pores by the alkali reduction treatment. The manufacture of artificial hair of the device system 30 shown in Fig. 8 is explained: First, the description is made of polyethylene terephthalate as a component, and 3 A method for producing and detecting artificial hair composed of a polyester-based synthetic fiber of the raw material. k. In the manufacturing apparatus 3 of Fig. 8, a polyethylene terephthalate is mixed with P-benzoate-f-acid glycol base as base material and containing coloring pigment The coloring resin particles are mixed in a predetermined ratio and placed in a raw material tank. The mixing ratio of the resin particles for coloring is changed to change the color of the artificial hair of the final product. The resin particles for coloring are compared with the polyethylene terephthalate. The mixing ratio of the formic acid glycol granules is a particle of polyethylene terephthalate. The mass ratio of the resin particles for coloring is at most 4 〇: 6 〇. The particles in the raw material tank 31 are transported to the melt extrusion. The machine 32 kneads the particles by the melt extruder 32, and the molten liquid is taken out from the extrusion port 32A, and the filament melt is solidified by the warm bath portion 3. The temperature of the warm bath portion 3 is in terms of productivity. It is preferably about 40 C. When the temperature of the warm bath portion 3 3 is too low, the molten resin is extruded, and when it comes into contact with the warm bath portion 33, the filamentous melt is first exposed to the outside of the water. In the inside, the internal resin is crystallized by rapid cooling, but the external crystal is not crystallized. As a result, a difference in molecular structure occurs, which is a cause of "wave wavy", which is not preferable. When the temperature of the warm bath portion 33 is too high, the filamentous melt is excessively crystallized, so that the durability of the filamentous melt for elongation is weakened, and the filament is easily broken when stretched, and the productivity is deteriorated. 318951 28 1353820 The first stage extension process is performed by the i-th extension drum 34 and the second extension drum 36 with respect to the solidified wire member, and the second stage extension process is performed by the second extension roll 36 and the third extension roll 38. The relaxation process is performed by the third extension roller 38 and the fourth extension roller 40. By the jth and second extension processes, the total magnification of the stretching ratio can be made six times. Then, the fibers subjected to the elongation treatment are subjected to the inspection and reduction treatment. Specifically, 'the treatment liquid of the accelerator mixed with the alkali solution for promoting the aqueous solution of sodium hydroxide or the like is stored in the liquid 6' as shown in FIG. 9 and will be suspended in a part of the rotating cylinder portion 47. The fiber 1〇〇 is immersed therein. At the same time, the treatment liquid is sprayed from the ejection port or the shower portion 48 of the rotary cylinder portion 47 to a portion of the fiber 1没有 which is not impregnated. The treatment liquid attached to the surface of the fiber (10) flows downward from the surface of the fiber along the axis of the fiber (ie, the length direction) due to the weight of the treatment liquid, and is treated like a sputum along the flow direction. . Accordingly, the fiber (10) can be made finer by the amount of reduction 1, and fine pores can be formed in the axial direction of the surface of the fiber. ^ The treatment liquid is preferably heated to a predetermined temperature in order to promote hydrolysis. Then, post-cleaning treatment for neutralizing the alkali attached to the fibers is carried out to obtain artificial hair. The diameter of the hole provided in the extrusion port 32A, the spinning condition of the temperature of the warm bath portion 33, the speed of the first to fourth extension rollers, and the first! The extension condition of the degree = degree of the ^ = groove, and the conditions of the reduction and reduction, so that the polyester-based synthetic resin having the composition of poly-glycolic acid glycol and color pigment has the same degree as natural hair. The cross-sectional dimension and bending stiffness thereby obtain artificial hair having the same degree of bending stiffness value 318951 29 1353820 as natural hair. For example, the spinning speed is 279 m/min, and the final winding speed is 155 m/min, and the bending rigidity value after alkali reduction is 6. 5 x 1 (T3 gf · cm 2 / strip of artificial hair. A method for producing artificial hair comprising a mixture of poly(p-citric acid) glycol and poly(p-butylene dicarboxylate) as a component and containing a coloring pigment is described. In the manufacturing apparatus 30 shown in FIG. The polyethylene terephthalate, the granules of the fat, and the particles of the polybutylene terephthalate vinegar, and the coloring of the poly-amp; The resin particles are mixed in a predetermined ratio and placed in the raw material tank 31. The particles of the resin for the I color are mixed with the total particles of the polyethylene terephthalate and the polybutylene terephthalate. The ratio is the total particle size of the polyethylene terephthalate and the poly(p-monobutylene monoester): the resin particles for coloring have a mass ratio of up to 40: 60. The temperature of the warm bath is set to 4〇. t: Left and right is better. Secondly, 'the labor with only polyethylene terephthalate and colored pigments In the same manner, the pellets in the raw material tank 31 are transferred to the melt extruder 32, and the melt 31A in which the pellets are kneaded by the melt-casting machine 32 is extruded from the extrusion port 32A, and then the bath is used. 33. The filament-like melt is solidified. In the same manner as described above, the solidified wire member is subjected to the i-th stage elongation treatment, the second-stage extension treatment, and the relaxation treatment, and the amount of the reduction is performed. Artificial hair can be obtained by neutralizing the alkali attached to the fiber and then washing the mixture. The mixing ratio of the particles of the polyethylene terephthalate and the particles of the polybutylene terephthalate , the artificial hair having the bending rigidity value of 318951 30 丄 兆 20 degrees with the natural: hair is obtained. The mass ratio of polyethylene terephthalate. In the range of 15:85 to ^.75, especially in the range of 20:80. When the mass ratio is less than ·5·:85, the value of the bending rigidity is higher, and conversely, when the mass ratio exceeds the bracket: π bending rigidity Artificial hair with a value deviating from the above range for f is used for wigs' When the artificial hair is different from the natural hair of the wig, the spinning condition of the diameter of the hole of the extrusion σ 32A and the temperature of the temperature of the bath portion 33 1 is less than ideal. 4 The extension condition of the speed of the extension drum, the temperature of the jth to the third dry heat sink, and the like, and the artificial hair having the most appropriate bending rigidity value can be obtained. A method of manufacturing the second artificial hair 5 and 6 of the bundle. Fig. 10 is a schematic view of the apparatus 50 used for the production of the second artificial hair 5, 6 'Fig. 11 is used in the manufacturing apparatus of the tenth item. Extrusion. A schematic cross-sectional view of the crucible. As shown in Fig. 1, the manufacturing apparatus 5 includes: as a sheath. a first raw material tank 51 for a polyamide resin of 卩5A, a second raw material tank for a polyamide resin as a core portion 5B, and a melt-kneading of a raw material supplied from the raw material tanks 5 and 52 The machines 51D and 52D are extruded from the smelting liquids 51A and 52A which have been kneaded by the melt extrusion machines 51D and 52D. The filamentous melt extruded from the extrusion port 53c of the P 53 is solidified while being raised to the surface of the embossed portion of the embossed portion; and then formed by the extension rollers, the crucible 59, and the dry heat grooves 56, 58, 60. a three-stage extension heat treatment step portion, a sand blasting machine 63 for forming a concavo-convex portion 5C on the surface of the wire, and a winding for winding up to a desired degree of artificial hair by a spray machine 63 31 318951 Ϊ 353820 machine 6 4 Composition. The melt extruder 51D' 52D has: a heating device for melting particles of the polyamide resin; a kneader for uniformly dispersing the agitation; and a gear pump for conveying the melts 51A, 52A to the extruding portion 53 (gear pump) 51B, 52B. The fiber extruded from the extrusion port 53C of the extruding portion 53 is passed through a warm bath, a dry heat and a hot-drying mechanism, and then passed through an electrostatic oil-repellent oil-filling device 6 and used for dimensional stability. The stretching drum 62 applied to the tension of the artificial hair and the sand blasting machine 63 for surface treatment are relaxed and wound around the winder 64. As shown in Fig. 11, the broadcast portion 53 has a double extrusion port arranged in a concentric shape, and has a semi-aromatic polyamine resin melt 52A extruded from the center circular portion 53B thereof, and The outer ring portion 53A surrounding the center circular portion 53B has a structure in which a linear saturated aliphatic polyamide resin melt 5 丨 A is extruded. Next, a method of manufacturing the second artificial hairs 5 and 6 using the above-described manufacturing apparatus 50 will be described. By using the manufacturing apparatus 50, each of the polyamide resins is melted at an appropriate temperature in the melt extruders 51d and 52D, and is sent to the extrusion unit 53 to semi-aromatically obtain the central portion mb from the extrusion port. The polyamide resin melt 52A and the linear saturated aliphatic polyamide resin melt 51A from the outer ring portion 53A are extruded from the extrusion port 53c to form a sheath/core structure yarn, and artificial hair 5 can be produced. 6, 6. Here, in the present invention, the linearly saturated aliphatic polyamine resin melt 51A is transported by the gear pump 51B for a certain period of time, and the semi-aromatic 318951 32 1353820 family of polyamide resin melt 52A is passed through the crucible. The example delivered by the fruit 52B is referred to as a sheath/core capacity ratio. In order to make the bending rigidity value of the artificial hair 5 close to the bending rigidity value of the natural hair, it is suitable as a weight ratio of a slight weight to a weight of 10/90 to 35/65. For the manufacturing conditions of the weight ratio of the sheath to the core, the core capacity ratio is preferably from 1/7, and the range is suitable for the artificial hair 5, 6 = value and the like. When the volume of the sheath A is larger than 1/2, that is, the effect of (4): the case change is large, and the effect of the core tube curvature of the human hair 5, 6 is increased, and the effect of π is reduced. When the "capacity ratio is less than two: hair = Γ: when the case becomes larger, the bending rigidity value is too large, and it is not similar to the eight '," hair, which is less desirable. The extension of artificial hair 5, 6 during spinning The magnification can be extended: the ratio is only the value of the artificial double of nylon 6: Π times. The second artificial hair 1, 6 two k stretch ratio, silk!, curved local 1 A job 4 can be based on the expected The shape of the sheath/core of the artificial hair 5 and 6 is the condition for spinning, and can be formed into a substantially concentric shape 31. The yarn can be properly squeezed when it is used for spinning. The surface of the chain-saturated aliphatic polyamine resin extracted by the outlet 53C, the matte gloss of ::#5A is removed, and the artificial hair can be produced, and the surface of the '糸" is given a fine ball. In addition to the use of the above-mentioned method, the method of producing a crystal is used in combination with the method of using a microparticle of 3J8951 33 1 1353820 sand, ice, dry ice or the like for chemical treatment. Method. By sandblasting method 'or' the wire table one, or These methods are suitable for imparting a suitable color and appearance to the artificial hairs 5 and 6, and may also be dyed (10) and/or dyed at the time of spinning, and may be dyed 5, 6 itself after the spinning. 'Because the second artificial hair _ 1J D has a sheath and structure formed by a polyaxial resin having different bending rigidity, it can reproduce the bending rigidity more rigidly than the conventional straight-chain saturated fat-polyamide.

Before the treatment, the bending rigidity value is about 1.6×10 −2 gf · cm 2 / strip when the mixing ratio is 20%, but if the proportion is increased to 75%, the bending rigidity value is reduced to about 6.7×1 〇gf · cm / bar. After the reduction and treatment, the bending rigidity value is about 1 2x10 2 gf . cm 2 / strip when the mixing ratio is 0/^, but if it is mixed, the case is increased to 2〇%, bending The stiffness value is reduced to about &&& 10 gf · cm / bar, the mixing ratio is about 6 〇, then about 5. 7 parent 1 〇 _3 to · cm / bar. $ poly-p-phenylene T-butylate Profile of 7 artificial hairs with different mixing ratios of glycol esters The diameter is 8 l 3 μm on average before the alkali reduction treatment and 71.1/zra after the alkali reduction treatment. According to the above results, 'the mixing ratio of polybutylene terephthalate is increased by 318951 41 1353820'. The bending rigidity value of the artificial hair is reduced to obtain artificial hair having the same degree of bending rigidity (6 5 to 7.8 x 1 (T3 gf · cm / strip) as the natural hair. For example, if it is known that no reduction and reduction treatment is performed, The mixing ratio of poly(p-butylene phthalate) is set to be about 7 to 80%, and when the alkali reduction treatment is performed, the mixing ratio of polybutylene terephthalate is set to about 20 to 60%. Just fine.

Fig. 15 is a view showing the bending rigidity values before and after the alkali reduction treatment when the mixing ratio of poly(p-butylene phthalate) is 2% by weight or 60%. The vertical axis is the bending rigidity value (gf · cm2 / strip), and the horizontal axis is the /3⁄4 D ratio of polybutylene terephthalate. It can be seen from Fig. 15 that by performing the alkali reduction treatment, the bending property value is from about 1.6 x 1 (T2gf · cm 2 / strip minus 4 to about 8 · 3 x 10 3 gf · c strip) at a mixing ratio of 2 G%. When the ratio is 6〇%, it is reduced from about · cmV strip to about 5. 7xi〇_3gf • purlin. The mixing ratio of polybutanic acid butane glycol vinegar is 20% and 60% of the cross-sectional diameter of artificial hair. At the alkali reduction

After processing, it is average. Oblique average 8G.4 (four) 'In the test reduction, it is known from the above that in order to reduce the cross-sectional diameter of the artificial hair, the rigid value of the same degree of natural hair is reduced, and the polyester is synthesized. Resin structure ^ alkali reduction treatment of the Japanese factory & "Fu Zhanzhi artificial hair 劁 [Example 7J 妁衣 w 疋 effective. In the same manner as in Example 1, a value of about 6. 5xl (T3gf · 2/ ', for the artificial hair of the structure of the curved rigid cm / strip, straight 庐, the dry polyester, the polyester fiber The experiment was carried out in such a manner that the hair treated by the artificial hair, and the treatment system was maintained in the environment of 18 ° C for two hours in the environment of the 318951 42 1353820 L of the tube of diameter 3_. In the case of the fineness ratio of the artificial hair, it is Ο.??%. [Example 8] Similarly to Example 1, the alkali reduction treatment was not performed in the same manner as in Example 7, and the bending rigidity value was about 12xl. The artificial hair composed of the polyester fiber of 〇-2gf · cm2 / strip and the diameter of about 75 " m was subjected to the same heat treatment as in Example 7. When the shrinkage rate of the artificial hair after heat treatment was measured, it was 1.55. When comparing Examples 7 and 8, it was found that the alkali reduction treatment can halve the heat shrinkage rate by the heat treatment. _ [Example 9] Next, the second artificial hair of the artificial hair bundle is obtained. A simulation experiment in which a pre-heat treatment is performed and mixed with the first artificial hair to perform a hot stamping process is confirmed. β 忍 弟 2 artificial hair with or without pre-treatment effect.

The i-th heat treatment is equivalent to the pre-treatment, and is in a state where the artificial hair is wound around the tube and extends in an environment of 16 〇t: 30 minutes. The second heat treatment is equivalent to the hot-rolling treatment of the strip processing, and in the same manner as the heat treatment of the third and fourth embodiments, the artificial hair is wound around the tube of the straight pack 30, at 18 (rc0々). The environment was maintained for two hours. 318951 43 1353820 [Comparative Example 4] In 4: = Comparative Example 4 of Example 9. In Comparative Example ", the second artificial heat was applied to the artificial hair similar to the yoke example 9.

Table 4 shows The case rate, and the table of the results of the two results in the heat shrinkage of each artificial hair = and the result is not the result of the example 9; the value after the heat treatment at the heat portion' and the result as the result of the comparative example 4: The value after L treatment. Fig. 16 is a graph showing the heat shrinkage rate of the artificial hair with respect to the bending rigidity value, and the vertical axis heat shrinkage = the bending rigidity value of the shafting system (...heart strip). Further, the plot ♦ is the bending rigidity value after the heat treatment of the crucible 1 , and the plot is the bending rigidity value after the second heat treatment, and the label is the bending rigidity value after the second heat treatment as a result of the comparative example 4. [Table 4] Bending rigidity value Xl〇-3 (gf · cm2/bar)

It is understood from Tables 4 and 16 that even the second heat treatment or the second heat treatment of 318951 44 or the enthalpy treatment of both are carried out. As a result of the embodiment 9, the thermal contraction rate Si caused by the heat treatment of the artificial hair is increased. Thermal hair gf · cm2 / strip of artificial hair 4 value of about 3 · 9x10 3 value of about 7.8xl (T3gi · Cfl] 2, the reduction rate of about 3%, bending stiffness m first and the first hair, heat shrinkage rate For the value of the bending stiffness value, 1 ..., the receiving / again depends on 0 / ^ r ^ , and is below the target range of 0.53 to 0.08 / 6. Relative to this, by μ 9 . From the results of the example 4, it was found that only the first =, 'the heat shrinkage rate is less dependent on the -flexor value, which is about 1.4%. Comparative Example 7 and Example 9 and Comparative Example 4. According to Example 7 As a result, the heat shrinkage rate of the artificial hair of the virgin artificial hair of the i-th artificial hair was 〇·%. According to the result of Comparative Example 4, the heat shrinkage rate of the polyamine-based artificial hair as the second artificial hair was 1%. As a result, the second artificial hair was also shrunk significantly more than the first artificial hair. Therefore, the polyester artificial hair used in Example 7 was mixed with the polyamine-based artificial hair used in Comparative Example 4 to carry out stripping. At the time of treatment, the polyester artificial hair adjacent to the polyamine-based artificial hair shrinks in the same manner as the polyamine-based artificial hair. However, 'no Polyamide-based artificial hair is pre-treated with polyester-based artificial hair for blending with polyester-based artificial hair, and polyester-based artificial hair with less shrinkage than polyamine-based artificial hair cannot be combined with polyamine-based artificial hair. As a result, it is not preferable to produce a wavy step difference in the artificial hair bundle. On the other hand, according to the result of Example 9, the heat shrinkage rate of the polyamine-based artificial hair as the second artificial hair is 〇. 5% or less, according to the result of the implementation of the example of 45 318951 1353820, the difference in heat shrinkage rate between the polyester artificial hairs of the i-th artificial hair is small, and therefore, the amine-based artificial hair is pre-extended by shrinkage. The treatment is heat-shrinked, so that no wavy step is generated. When the artificial hair bundle of the present invention is formed to the same extent, the (four) rate can be obtained by previously performing heat treatment on the polyacrylamide fiber of I.

The method of "Cheng 2 ΐϊ天 = the same degree of size and bending rigidity value, the poly =::= glycol ester and poly-p-phenylene The butane carboxylic acid vinegar forms artificial hair with a predetermined mass of two filaments, and in this way, artificial hair composed of the constitutive hair can be provided. Thus, the poly-I-fiber can not be bundled by itself, and can be suppressed. The bundle of polyamine fibers is the same as the natural hair: it is a property value. In addition, the artificial hair of the polyester fiber is made up of the artificial hair, and the hair is made of polyamine fiber. The second artificial hair having the same size and bending rigidity as the W hair 1c is mixed in a predetermined ratio, and the second can be suppressed.
