Abstract

Provided is an artificial hair having aesthetic properties such as appearance, tactile sensation and texture resembling nature hairs as well as appropriate physical properties resembling nature hairs. Also provided is a wig using the artificial hair. An artificial hair (1) has a sheath/core structure formed with a core portion (1B) and a sheath portion (1A) covering the core portion (1B). The core portion (1B) is formed of a polyamide resin, particularly a semiaromatic polyamide, and the sheath portion (1A) is formed of a polyamide resin having a bending rigidity lower than the core portion (1B), particularly a linear saturated aliphatic polyamide. Thereby, for example, the bending rigidity of the artificial hair can be adjusted to be a value approximate to nature hairs, while behavior thereof also can be controlled to be extremely approximate to nature hairs. Since a wig using said artificial hair as source material has nature aesthetic properties, it has an excellent appearance.

Description

1275360 IX. Description of the invention: [Technical field to which the invention belongs] The physical properties and texture of natural hair. The present invention relates to the use of artificial hair, and the use of the hair. [Previous technique] Since ancient times, wigs have been preferred to use: :: ar years are subject to natural hair material scheduling == Synthetic fibers are manufactured as wigs for wool. In this case, the synthetic fiber to be used is similar to the natural one, and the artificial hair material used for the first selection target is a synthetic fiber such as an acrylic type or an amine type. Generally, the fiber (4) 乂-U is poor. Therefore, the hair style after the latent hair setting is poor, for example, if it touches the warm water, it causes weakness such as curling and the like. Although the polyester fiber is excellent in strength and heat resistance, it has a 'bending rigidity value' which is too high in addition to the low moisture absorption under natural hair*, so it will be presented, for example, in a high-humidity environment. The appearance, touch, and physical properties that are different from those of natural hair, and the use of the « is not a sense of sensation when it is used. The so-called "bending rigidity value" refers to the texture and texture of the fiber. The physical property value of the fiber can be measured by the Kawabata method, and the physical property value widely recognized in the fiber fabric industry (see Non-Patent Document 1) has been developed to measure the bending rigidity value of one fiber or hair. (Refer to Non-Patent Document 2). The bending stiffness value is also called "bending stiffness", and 317860 5 1275360:f is defined as the ship that changes with the (four) change when a unit-sized torque is applied to the artificial hair. The larger the rigid value of the artificial hair (four) material, the less likely it is to bend, that is, the artificial hair that is hard and difficult to bend. On the contrary, the smaller the bending rigidity value, the artificial hair that will be licked. (4) Gu Yi Zun Qu can be described as a soft day." (4) Amine fiber from most points of view, it will provide close to the use of color, the physical and physical properties of the hand, and thus from the past, the actual use for the false heart: especially hunting The manufacturing method proposed by the applicant of the present application to eliminate the unnatural luster by surface treatment (refer to the patent literature!) ^ 'provides a superior false connection: =?

With the help of the Guardian®, it is closer to the real issue of the wig, so that the wig will naturally give birth to the original appearance, and the user will not be found wearing a wig. [Effects of the Invention]

The root is provided with a mirror, a structure, a physical property (especially a bending rigidity), and an artificial hair which is produced by humidity and whose right pole is close to natural hair. In addition, a wig of __two xiao/heart structure artificial hair, Compared with the conventional use of a wig composed of a single δ fiber-forming material, the former can impart a natural feeling to the wearer and the surrounding observer. The artificial hair formation will bend the rigidity lower than the core. The polyamide resin is used as a sheath, and the sputum is a point, and the nickname is a sheath/heart structure. When the squid is obtained, the degree of fit, 、, and degree can be changed to change the laterality of the koji, showing that it is closer to the true issue. Artificial hair, as a result, the artificial hair according to the present invention, even in the state of curling, causes curling and straightening when wetted by water, and when it is naturally placed to remove moisture and return to curl, it can be similar to natural The behavior of the hair. Therefore, according to the wig of the present invention, when the wig is worn in a rainy or high-humidity environment, the artificial hair has a characteristic that the bending rigidity value changes due to moisture absorption (ie, The degree of increase leads to a decrease in bending rigidity.) Artificial 10 317860 1275360: Although the hair will become soft and sag and lose its hair, if it is self-released, it will absorb the moisture of the γ, but it will naturally be placed and dried.

In order to eliminate the unnatural death of the surface of such artificial hair 1, a so-called matting treatment can be performed. ‘No, the figure does not change the artificial hair of the present invention, but the lengthwise direction of the upper door 不, 思思®, 1 Α surface will form έ, 图. As shown in the figure, the sheath portion of the artificial hair, the sputum, and the Tiancheng embossed portion lc. When the &% of such fine uneven portions π 317860 12 1275360 is formed, random reflection occurs when light is irradiated onto the artificial hair 10. Therefore, the surface of the artificial hair will have a so-called "matting effect" due to the reflection phenomenon caused by the light irradiation. The fine concavo-convex portion 1C may be formed by spinning the artificial hair i or by spinning the fibers with a fine powder such as sand, ice or dry ice. When the 4 4 ' formed in the spinning of the artificial hair is formed as long as the spherulites are formed on the outermost surface of the artificial hair i. In the case of ^, it is also possible to adopt a spherulite formation and a group of the above-mentioned blasting treatment using a fine powder such as sand, ice or dry ice. ^ ^ ^ ^ ^ 7, and σ-type treatment. Such a recessed _~ portion is formed by a combination of spherulites or a rubbing treatment to scatter light, and it is only necessary to form a concave-convex portion ic having a larger visible light wavelength level. "This U-man's hair UQ system can be used in conjunction with the consumer's preference; the coloring system can be used in the mixing of the raw material polymer during spinning, and the artificial hair is dyed after spinning. According to the artificial hair 1, 10 of the present invention, by using the polyamine which has a high bending rigidity for the core portion 1B, the A 仗 uses the bow to make the sheath portion 1A use a convergence which is lower in bending rigidity than the crotch portion 1B. The amine, which constitutes the sheath/core structure, once changes the bending stiffness, and the thought/span, wet, y, and y is closer to the artificial hair that is actually released. In addition, according to the sheath, 10 will produce matting. The effect is the artificial hair and texture of the face e L. "The physical property value of the artificial hair can be more approximated, and the method of manufacturing the hair of the present invention is shown in the figure 3 of the present invention. Spinning 317860 13 1275360: Machine schematic, Figure 4 is a diagram of the spinning machine. As shown in Fig. 3, the spinning machine 2 () is provided with a second slitting tank 22, a discharge portion 23, a melting tank 21, a tank, a water bath, a 24, and a ramie coiler. 34. Among them, the first! The melting tank 21 is a resin (four) melting tank which is a portion a 2 (four). The second melting tank 2 2 is a core portion B : = amine: =: dazzle: groove. The discharge portion 23 discharges the turbid liquid 21 Α, 22 仏 from the material sump. The warm water bath 24 solidifies the filamentous molten material discharged from the discharge port 23C of the discharge portion 23, and forms uneven portions on the surface. The jet mill 33 is formed by extending the embossing portion by the extension _ 25, 27, 29 and the dry heat groove 26, 28 = type heat treatment step portion, and then further stepping the convex portion 2 on the surface of the wire ^. The winder 34 winds the artificial hair that has been subjected to the required degree of matting by the mill. The melting layer 21, 22 is provided with a heating I for melting the melamine resin particles, and gear pumps 21B and 22B. In the case of the gear, the screw (4) is provided with a screw or the like which is supplied to the discharge portion 23, and the molten liquid 21A, 22A is supplied to the discharge portion 23 by liquid. The fiber discharged from the discharge portion 23 is discharged as shown in the figure, after the overheated water bath, the extension, and the dry heat mechanism, and then passed through the antistatic upper/coating 31 extension roller 32 and the surface treatment spray. The mill 33 is wound around the roll machine 34. The stretching roller 32 relaxes the tension applied to the artificial hair to stabilize the size. As shown in the figure, the "discharge portion 23" has a double-layer discharge port arranged concentrically, and has a semi-aromatic polyamide 14 317860 1275360 tree "melt 22A" from the center circle portion 23β, and from the center circle The structure of the outgoing direct-bonded saturated aliphatic poly-resin molten solution 21A of the portion 23B, the manufacturing of the melt-blown liquid 21A, and the use of the above-mentioned spinning machine 20: the use of the above-mentioned spinning machine 2, in the melting tank 21, 22 according to the appropriate temperature of the relay, and then sent to the second = round part is now spit out semi-aromatic polyamine resin smelting liquid = coffee department 23A spit out the linear saturated aliphatic polyamine resin melt solution and spit out from the spit ^ 23C The silk of the sheath/core structure is formed, and the artificial hair 1, 10 can be produced. At this time, the linear saturated aliphatic polyamine resin melt 2 i A is carried out by using M21B for a certain period of time, The ratio of the capacity of the semi-aromatic polystyrene ς 曰 曰 曰 曰 Α Α Α Α 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 齿轮 。 。 。 。 。 。 As will be described later, in order to approximate the bending rigidity value of the artificial hair 1 近似 to the bending rigidity value of the natural hair, it is preferable to set the sheath/core weight ratio of the saddle disk φ to the weight ratio in the range of 1 〇 / 9 〇 to 35 / 65. . In order to obtain the sheath-to-core weight ratio, it is preferable to set the sheath/core capacity ratio to a value of two 1/2 to 1/7, which is suitable for physical properties such as bending rigidity of the artificial hair I, " value. If the saddle/core capacity ratio is more than 1/2 (instead of increasing the ratio of the sheath portion 1Α), the effect of increasing the bending strength value of the core portion of the artificial hair u〇 will be small. On the other hand, if the sheath/core capacity ratio is less than 1/7 (in other words, the ratio of the core portion 1B is increased), the bending rigidity value becomes too large to approximate the natural hair, which is not preferable. The stretching ratio of artificial hair 1,1 〇 at the time of spinning can be set to 5 to 6 317860 15 : 1275360 : two is =: times: ! It is known that the ratio of artificial hair of nylon 6 alone is about 2, silk, f Qu Gang = month value white = work for hair man uo towel 'spinning time when spinning. In this case, UP should be set appropriately. ,, Β±,, iic The sheath/core shape of the woo uo can be formed into a slightly concentric shape by appropriately pressing the spinning (4) condition. The spinning for artificial hair of the present invention is made by spinning the straight-chain saturated aliphatic polyamine tree from the discharge port 2 and the crucible in the warm water bath 24 In the spherulites of the 1A ic, the surface of the enamel is grown to have an unnatural luster of the uneven portion, and the appearance of the natural light is the same as that of the natural hair, and the artificial hair 10 can be produced. The method of the second C concavo-convex portion lc 'except for the above-mentioned growth ball ice, dry ice, etc., such as: using a method of sanding, a method of treating the silk surface after the wire is visited, or a method of performing a drug method on the surface of the wire, or These methods are combined as appropriate. UQM can be adjusted to give the appearance of 'color'. When spinning, it can be used to dye the artificial hair itself after the spinning. According to the seventh and the second, because the artificial hair of the present invention has a Le/core structure which is composed of a curved rigid amine tree, and thus the reproducible single-family tr is more rigid than the conventional one. Aliphatic polyamine resin, a single catty, artificial hair uo into artificial hair. Further, by forming the fine uneven portion lc on the surface of the artificial hair: the natural appearance of the natural hair can be imparted, and the natural appearance of the hair can be imparted. The person-to-person will be described with respect to the use of artificial hair 317860 16 1275360 according to the second embodiment of the present invention. Fig. 5 is a perspective view showing the rice ft structure using artificial hair according to the second embodiment of the present invention. Using the artificial hair wig of the present invention, the human hair is planted in the wig substrate 41! The false heart wig substrate 41 constructed of 1Q or the like may be composed of a mesh substrate or an artificial skin substrate. The case of the figure is the state in which the planting is performed in the mesh member mesh of the wig substrate 41. The wig base 41 can also be combined with a mesh-like base and an artificial skin base, and is not particularly limited as long as it is designed and used for the wig. The diameter of the artificial hair 1, 10 is as long as it is about 0 05 to 〇 lmm. Further, it is preferable to use artificial hair 1Q which has a specular gloss of the suppressed surface and which has a natural hair luster. The color of the artificial hair UG can be matched with the needs of the wearer, and the color such as black, brown, and golden yellow is appropriately selected. ^ With the original hair around the user's bald area, choose the artificial hair with the color to increase the natural feeling. When the fashion wig or the hair extension wig is formed, the artificial hair of the present invention can be colored to a different original color to form a mesh shape, or the artificial hair can be applied from the root to the hair tip, for example. A color change such as a gradation of a color change/infancy change or a gradual change in color. Figure 6 is a magnified view of the behavior of the wig as shown in Figure 5 for humidity changes, (A) is the normal humidity state, and (B) is the high humidity state. In the figure, the straight hair condition in which the artificial hair is straight is exemplified. As shown in Fig. 6(A), the artificial hair 1, 10 implanted in the wig 40 of the present invention has a bending rigidity value similar to that of natural hair. Therefore, in the ordinary environment before and after the humidity of 40 to 60%, artificial hair, the standing condition is good and the wig 40 has a sense of volume. 317860 1275360 In contrast, when the wig 40 of the present invention suffers from (4) or wears a wig under a high-humidity nuclear environment, the artificial hair of the wig is changed by the moisture absorption of the artificial hair. (ie, as the thirst rises, the bending stiffness value will decrease), the artificial hair will become softer, and ^6 and B) will not sag and will lose its sense of volume. However, if the absorbed moisture, or placed or dried to dehumidify, the human jade hair will gradually stand, and the sub-state will return to its original state. • In addition, when the artificial hair H0 is curled, the curling extension of the natural hair is formed, and the method of stretching is performed, and as in the case of straight hair, if the & knife is placed, the knife is placed naturally. Or dry and dehumidify to restore the curl. According to this U, the rice t 4Q 'uses the core system, and the flexural rigidity of the polyammonium is used, and the sheath portion 1A uses the artificial hair uo which is less rigid than the core 1B: the glutinous rice/heart structure. And it is planted in the wig "in the wig" and thus has the temperature and humidity to change the bending rigidity, and the sensation and behavior of the hair will be able to obtain a good appearance. In addition, when the artificial hair is In the case where the fine uneven portion 1C is formed on the surface, the effect of the natural hair can be exhibited by the effect of the day. The rice meal of the rice field of the moon is wet or wet, or the water is absorbed by the wearer's sweat. Japanese sheep, eight $t for artificial hair 1,10 series use hydraulic t-fat, so due to the absorption of water, artificial hair U0 droops with weight = plus, 俾 shows behavior similar to natural hair. In contrast, for example, when When borrowing a Shiva wig, because the bending is just :::: a wig that writes red artificial hair and a combed hair and a blended /C hair', thus wearing the artificial hair of the I/, rice hair, will be due to 317860 18 :1275360 Moisture adhesion, while making the original Hanging on the side of the scalp, but the artificial hair of the polyester remains in a standing state, so that the hair of the wig formed by the polyester will be separated from the original side and exhibit an unnatural appearance. However, in the present invention, if the moisture The hair attached to the wig will also be drooped like the original drooping without causing the hair to separate from the turtle, so the original and artificial hair will maintain a good condition.

This phenomenon is known to be made. The artificial hair of Nitro 6T and Nylon MXD6 will exhibit a higher bending stiffness value than that of artificial hair using nylon 6 or nylon 66. Therefore, it was found that the artificial hair-based core portion 1β of Examples 1 to 10 used 2: a nylon 6Τ or a nylon MXD0 having a relatively rigid rigidity, and the sheath portion 1Α was used to have a bending rigidity value. Lower than the core 1 Β Dragon 6 or nylon 66 composed of polyamine resin, 26 317860 • 1275360 (Table 4) Comparative Example 1 Comparative Example 2 Comparative Example 4 Using resin: Nylon 6 Nylon 6 Τ Nylon MXD6 At 22 ° C, Bending rigidity value in each humidity (xl0'5gfcm2) 40% 510 980 940 60% 340 920 870 80% 250 860 780 Next 'For artificial hair prepared by the above Examples 1 to 1 and Comparative Examples 1 to 5 The characteristics are explained.

The sheath/core capacity ratio is 1/丨, and the wire diameter is 8〇JLim. The stretching ratio is 5·5. As can be seen from the figure, the interface between the core 1Β and the sheath 1Α will be peeled off, and the fiber will appear white, and the color of the colored color will be discolored. The core structure is not suitable for artificial hair.

Next, the measurement results of the artificial hair bending rigidity values of the examples and the comparative examples will be described. The bending rigidity value is a physical property value generally used for fibers and the like as described above, and in the case of hair, it has been determined in recent years to belong to the texture (appearance, touch, and texture of the chest property). For the measurement of the related fabrics, the Kawabata measurement f and its principle are widely known, so the single-bend test & machine (KATO TECH, model Ms_fb2_sh) improved by this method is used to measure the artificial == The rigidity is measured. The measurement method is based on the artificial hair and natural hair of the actual comparative example of the present invention, and the hair is smashed at the same speed for each 1cm spoon. 0 arc until a certain melody: the slight, f-curvature moment generated by this ##曲, and the relationship between the measured moment, the bending moment and the curvature of the curvature~ then the bending moment/curvature change is used to find the usual The flexural value is representative. The typical measurement conditions are as follows: (measurement conditions) Distance between the central claws: lcm 317860 28 1275360: Torque detector: Torsion wire (wire) Torque torque sensitivity: l.〇gf · cm ( Full width 10V) π 'Bei 1 mode curvature: iS^crtT1 Bending displacement speed: 0.5cnrVsec Measurement period: 1 round trip f ''The mechanism of the claws respectively sandwiching the above-mentioned hairs lcm. Figure 12 shows the embodiment 1 to 5 and Comparative Examples i and 2, the humidity dependence of the hair bending rigidity value. In the figure, the horizontal axis is >^^ the vertical axis is the bending rigidity value root). The temperature system 22 was measured. 〇 = ^, 12 In the figure, the artificial hair of the examples and the comparative examples are shown together: the humidity dependence of the sex value, and the natural hair characteristics. Because the individual difference of the day is large, the hair of 25 males and 38 females is taken in all age groups from 2〇 to 5〇, and the T-curvature value of the diameter (10) drop sample is measured. The average value is set to the standard value, and the large value and the minimum value are also shown in the figure. The average value of the bending rigidity of natural hair is root and 51 〇><1〇_5^coffee 2/ root in humidity 40/〇 and 80%, respectively, and it is known that the humidity decreases almost monotonously with the increase of humidity. characteristic. On the other hand, the maximum value of the bending rigidity of the natural hair is 74〇xl〇-5gfcm2/root, 6〇〇xi〇.5gfcm2/root in the humidity of 4〇% and 80%, respectively. Further, the minimum value is 66 〇 x l 〇 5 gfcm 2 / root and 42 〇χ 10 gf cm 2 / root in the humidity of 40% and 80%, respectively, and it is known that the bending rigidity value of the natural hair has a range. The artificial hair 10 of Example 1 has a wire diameter of 80 μm and a sheath/core volume ratio of 1/7'. Under the condition of humidity of 40%, the bending rigidity value is equal to 74 〇 xl0 to 5 gfcm 2 of the maximum value of natural hair of 29 317 860 and 1275360. The root, and with the increase of humidity, the bending rigidity value is gradually reduced, and is reduced to about root at a humidity of 60%, and is reduced to about 65 〇xl 〇 5 gfcm 2 / root at a humidity of 80 ° / °.

From this result, it was found that the leaf belonging to the artificial hair of Example 1 showed no bending rigidity value higher than the bending rigidity value of the natural hair, and was composed of nylon 6 as compared with the comparative example described later. Artificial hair and Comparative Example 2, under the bending rigidity value of the artificial hair composed of nylon 6T, showed a bending rigidity value and a humidity dependency similar to natural hair. The fine hair of Example 2 is an artificial hair 1 〇 series green diameter 80μηι, sheath / core capacity ratio of 1 / 5, under the condition of humidity 40%, its bending stiffness value is the root, the same as natural hair, and the humidity is rising to 45% Previously, the bending stiffness value gradually decreased to about 65 〇 xl 〇 -5 gf cm 2 / root. Secondly, the humidity rises to 45 to 60%, and the bending rigidity value is about 65 〇 xi (r5gfcmf root is in a fixed state, and then, when the humidity rises to 6 () to 8 ()% _, the f-rigidity value is Gradually, it is reduced to about 60〇xl (r5gfcm2/root when the humidity reaches 8〇%. From this result, it is found that when it is the artificial hair of Example 2, it is natural at 40% humidity. The f-curvature value of the hair is the same, the month increases with the humidity, and the bending rigidity value decreases, and the bending rigidity value and the humidity dependency similar to the natural hair are displayed. The artificial hair of Example 3 is different from the embodiment i. The point is that Le /. Under the condition of humidity 4〇%, the bending rigidity value is -^ 72〇X 1 〇_5 fine 2/root ' is the same as natural hair, and the humidity is 40 to 60% ” The system is gradually reduced, and is reduced to about 52GxiG_5gf(10)2/ 317860 30 1275360. Secondly, the humidity is 6〇5; 80〇/Β-^. to 8〇/°蚪, the bending rigidity value is gradually reduced, and the humidity is about 48〇xi(r5gW/root. From this result, it was found that in the case of only the artificial hair of Example 3, the humidity was 40%. Nowhere / Seven and (3) Love ^ _ A,., , ', the bending stiffness value of the cool hair of the day is the same, the humidity of the array rises, the bending rigidity value causes the k jj r king value to decrease, and even if the thirst shows the pole Close to the 铗 铗 髟 & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & In the 锴 / core 罝 ratio is W2. In the thirsty sound 4η. / & μ, Le / 72 〇 xl 〇 -5gfcm2 / root, * horse "large ..., hair is the same, and the humidity is 4 弯曲 bending stiffness value The gradual decrease in the value of the bending force is reduced to about 51〇xlo-5gfcin2/ root, and the bending stiffness value is gradually reduced when the human/filament is 60 to 80%. When the humidity is 80%, it is about 39〇xl〇_5gfem2/root. Main reason: It is known that when it comes to the artificial hair of Example 4, 'when the humidity is 4〇%, it is the same as the natural hair. The stiffness value of the curve - caused by the increase in humidity, the bending stiffness value decreased, while the humidity of 8〇%, the % curvature value was near the minimum value of the natural hair-curvature value. The reason why the bractling bending rigidity value is lower than the humidity is not lower than the value of the first embodiment, because the capacity of the sheath portion 1A is larger than that of the implementer (that is, the capacity of the core portion 1B is small). Therefore, the artificial hair of the present invention can change the humidity dependence of the bending rigidity value by changing the ratio of the capacity of the core/core. Thus, it can be seen that when the artificial hair of Examples 2 to 4 is in the case of humidity, 40% is consistent with the natural hair bending tolerance value, and with the increase of humidity, the bending rigidity value is reduced, and it shows the similarity of natural hair = 317860 31 1275360; The artificial hair 10 of Example 5 differs from Example 1 in that the sheath / 1A is composed of nylon 66, and the rest are the same. In Example 5, under the condition of 40% humidity, the bending rigidity value is greater than 78〇xl〇gfcm2/root of natural hair, and the bending rigidity value decreases almost linearly before the humidity rises to 4〇%%%. When the humidity is 50%, it is about 65〇xl〇-5gfcm2/root. Then, when the humidity is 50 to 80%, the slope is almost the same as that of the embodiment j, and the bending rigidity value is reduced to about 6〇〇Xl. 〇-5gfcm2/root. As a result, it was found that when the artificial hair 10 belonging to Example 5 was kept at a humidity of 40%, it showed a value larger than the natural hair bending rigidity value, and the bending rigidity value decreased as the humidity increased. In the case of the artificial hair of Example ^, the bending rigidity value showed a value larger than the values of Examples 丨 to 4 in the same range in the range of humidity 40% to 50%. From this, it can be seen that when the artificial hair of Example 5 is used, the bending rigidity value close to the bending rigidity value of the natural hair is not displayed, and as the humidity increases, the bending rigidity value decreases, and the display is displayed. It is similar to the humidity dependence of natural hair. The artificial hair of Comparative Example 1 was composed of nylon 6, and had a wire diameter of 80 μm and an elongation 彳 σ of 3. 3 . § In the case of artificial hair, the bending at a humidity of 40%, the value of about 51 〇χ 1 〇 -5gfcm2 / root, about 7 % of natural hair. Further, as the humidity rises, the bending rigidity value is almost monotonously reduced, and in the case of humidity, the bending rigidity value is about 25 〇 x 1 〇 -5 gfcm 2 / root. This value is approximately 50 〇/〇 of natural hair. Learn about the comparison! The flexural rigidity values were significantly less than the natural hair and Example i to the working hair in the total measured range of 317860 32:1275360:humidity. The artificial hair of Comparative Example 2 was composed of nylon 6T and had a wire diameter of 80 Å and an elongation of (4) 5.5. In the case of the artificial hair, the flexural rigidity value at a humidity of 4% is about 98 〇 x 〇 -5 gfcm 2 / root, which is about natural hair. Larger value. Further, as the humidity rises, the bending rigidity value is almost monotonously reduced, and at a humidity of 80%, the bending rigidity value is about .._xl 〇 -5 gW/root. This value is about 17% of natural hair. It was found that the flexural rigidity value of Comparative Example 2 was significantly larger than the natural hair and the artificial hair of Examples 1 to 5 in the measured total humidity range. Further, in the case of Comparative Example 3, as described above, the portion ia and the core portion 1B are peeled off and cannot be used as artificial hair, so that the measurement of the bending rigidity value is performed by the helmet method. Next, the humidity dependence of the artificial hair bending rigidity values of Examples 6 to 1 will be described. Fig. 13 is a graph showing the humidity dependence of the artificial hair material rigidity values of Examples 6 to 1 and Comparative Examples 1, 4, and 5. In the figure, the horizontal axis represents humidity (%), and the vertical axis represents f-curvature value (1 〇 -5 gfcm 2 / root). The temperature is measured as hunger. In Fig. 13, as in Fig. 12, the f-rigidity values of natural hair will be combined to mark their average value, maximum value, and minimum value. The artificial hair 10 of the K example 6 is the same as the embodiment in that the core (3) is composed of the nylon IIMXD6, the wire diameter is 8〇μηι, and the sheath/core capacity ratio is 1/7. ^ It can be seen from Fig. 13 that when the artificial hair belonging to the embodiment 6 has a bending rigidity value of 40% under the condition of 40%, almost the average value of the natural hair (four) And as the humidity rises, the bend 317860 33 : 1275360 - the stiffness value gradually decreases. At 60% humidity, it is reduced to about 66〇Xl (r5gfCm2/root, and at 80% humidity, it is reduced to about 60〇xl〇-5gfcm2/root. From this result, it is known that it belongs to Example 6 The artificial hair is the same as the bending rigidity value of the natural hair, and the bending rigidity value is reduced by less, and the bending rigidity value is decreased as the humidity increases. It is similar to the behavior of natural hair. That is, it can be seen that the human hair β 0 system of Example 6 exhibits a bending property similar to that of natural hair and humidity dependence. 2. The artificial hair of Example 7 is different from that of Example 6. The ratio of the sheath core capacity is 1/5, and the rest are the same. ^ Item 13 It can be seen that when the artificial hair 10 belonging to the embodiment 7 is on the day τγ' under the condition of humidity 40%, the bending rigidity value is 73. 〇xi〇, fcm2/root., almost the same as the average value of natural hair, and then, as the humidity rises, it decreases to the value of 62〇xl〇_5gfcm2/root. ♦Secondly, Before the humidity rises to 6〇%, the bending rigidity value gradually decreases, and when the humidity is 60%, it decreases to (4) xi -5gW/root. The bending rigidity value gradually decreases when the humidity is 6〇 to 80%, and is 56〇xl (T5gfcm2/root) at a humidity of 8〇%. From this result, it is known that it belongs to the seventh embodiment. In the case of artificial hair, π is a bending rigidity value which is almost the same as the bending rigidity value of natural hair when the humidity is 40%, and the bending rigidity value is decreased as the humidity rises, and there is no behavior similar to natural hair. That is, it is understood that the artificial ash 1 〇 of the embodiment 7 shows a bending rigidity value similar to that of natural hair and a humidity dependency 317860 34 1275360. The artificial hair of Example 8 is different from that of the embodiment 6 in the ratio of the anger capacity. It is 1/4, and the rest are the same. From Fig. 13, it can be seen that 'when it belongs to the artificial hair 10 of the embodiment 8, the bending rigidity value under the condition of humidity 4〇% is 73〇xi 〇-5gfcm2/ = 'Almost the same as the average value of natural hair, when the humidity is 4〇 to 6〇%• The value of bow η] is reduced. 'When the humidity is about 6Q%, the bending rigidity value is reduced to 560x10-^-2/root. When the humidity of the owner is 60 to 80%, the bending rigidity value is gradually decreased, and the humidity is lowered at 80% humidity. Up to 49〇xi〇-5gfcm2/root. From this result, it is found that when the artificial hair 10 belonging to the embodiment 8 is reduced by 4 ()%, it is almost the same as the bending rigidity value of the natural hair. The bending value of the bow is 'and the value of the bending rigidity decreases with the increase of the humidity, and the behavior similar to the natural hair is not shown. :::9 The artificial hair 10 is different from the embodiment 6 in the heart valley 1 ratio is 1/ 3, the rest are the same. Production) two first household 13 map can be informed 'when the artificial hair belonging to the embodiment 9 ^ humidity 4〇% condition bending stiffness value is 73〇xl〇-5gfcm2 / ^ almost The same as the average value of the natural hair, the bending rigidity at the humidity of 4 〇 to 6 〇% (4) is lowered. When the humidity is about 60%, the bending rigidity value is lowered to 1 〇 gfcm / root. Secondly, when the humidity is between 6 〇 and 8 〇%, the bending rigidity 糸 is gradually lowered, and when the humidity is 8 〇%, it is lowered to 44 〇χΐ〇 5 (10) 2 / root. From this result, it is found that when the human hair belonging to the embodiment 9 is in a state of humidity of 4%, the bending rigidity value with the natural hair is almost the same as the moon phase 317860 35 : 1275360 H = the rigidity value 'and the humidity The rise, the bending rigidity value is reduced, and the behavior similar to natural hair is not found.

According to the artificial hair of Examples 1 to 10, The sheath is set to nylon 317860 37 : 1275360 :: or = 66 ' and the core is set to nylon 6T Nylon μ·, by changing the ratio of the capacity, you can get the human jade hair 1Q with the f, the position value and the humidity according to 2, which are similar to the natural hair. The second figure is used by the figure and the fourth (4), ~邛1B or Nylon mxd6, and the sheath/core capacity is close to 1/2. The bending stiffness value of the artificial hair is 附近, which is near the minimum value of the natural hair bending rigidity value, and the artificial energy produced by the yule/core capacity ratio Μ The hair (4) bending stiffness value is near the maximum value of the natural hair bending stiffness value. • It is known that the core (7) is set as a semi-aromatic polyamine resin, and the sheath portion 1A is set as a sheath/sheath structure artificial hair of an aliphatic polyamide resin, and the capacity ratio of the rod/core is 1/2. In the case of the range of 1/7, artificial hair that approximates the behavior of the natural hair bending rigidity value can be obtained. As shown in Table 2 and Table 2, the sheath/core capacity ratio of 10 (10) by weight in the range of 1/2 to 1/7 will be in the range of the touch-to-touch range. In particular, in Examples 6 to 10. When the sheath is set to nylon 0 and the core is reluctantly made into artificial hair 10 of nylon MXD6, at a temperature of 22, the bending rigidity value at 40 to 50% is between the maximum and minimum values of natural hair. And shows behavior close to its average. Further, in the humidity range of humidity of 50% or more, the artificial hair w bending rigidity values of Examples 6 and 7 became behavioral characteristics close to the maximum value of the natural hair bending rigidity value, and the artificial hair 1〇 bending rigidity value of Example 8 was The behavioral characteristics close to the average value of the natural hair bending rigidity value, and the artificial hair 10 bending rigidity values of Examples 9 and 1 are behavioral characteristics close to the minimum value of the natural hair bending rigidity value. 317860 38 : 1275360 : Next, the artificial hair of the embodiment is explained by the change in moisture absorption.
