Description

本発明は、繊維の測色に関する。 The present invention relates to colorimetry of fibers.

繊維（例えば、毛束）を測色する場合、エッジロスエラーによって実際より暗い色として測色されることにより、繊維を目視評価した結果に近い測色結果が得られなくなる。 When measuring the color of fibers (for example, hair bundles), edge loss errors cause the color to be measured as darker than the actual color, making it impossible to obtain color measurement results that are close to the results of visual evaluation of the fibers.

なお、毛束の測色に関しては色々な技術が知られている（例えば、特許文献１、特許文献２および特許文献３を参照）。 Note that various techniques are known regarding color measurement of hair bundles (for example, see Patent Document 1, Patent Document 2, and Patent Document 3).

第一の実施形態にかかる繊維保持具１の平面図（図１（ａ））、正面図（図１（ｂ））である。They are a plan view (FIG. 1(a)) and a front view (FIG. 1(b)) of a fiber holder 1 according to a first embodiment. 第一の実施形態にかかる繊維保持具１に繊維１０を保持させたときの平面図（図２（ａ））、正面図（図２（ｂ））である。They are a plan view (FIG. 2(a)) and a front view (FIG. 2(b)) when the fiber 10 is held by the fiber holder 1 according to the first embodiment.

以下、本発明の実施形態を図面を参照しながら説明する。 Embodiments of the present invention will be described below with reference to the drawings.

第一の実施形態
図１は、第一の実施形態にかかる繊維保持具１の平面図（図１（ａ））、正面図（図１（ｂ））である。図２は、第一の実施形態にかかる繊維保持具１に繊維１０を保持させたときの平面図（図２（ａ））、正面図（図２（ｂ））である。 First Embodiment FIG. 1 is a plan view (FIG. 1(a)) and a front view (FIG. 1(b)) of a fiber holder 1 according to a first embodiment. FIG. 2 is a plan view (FIG. 2(a)) and a front view (FIG. 2(b)) when the fiber 10 is held by the fiber holder 1 according to the first embodiment.

第一の実施形態にかかる繊維保持具１は、支持面４Ｓ、底部４Ｂ、一対の突起２ａ、２ｂを備える。なお、支持面４Ｓおよび底部４Ｂが支持体を構成する。すなわち、支持体は、支持面４Ｓおよび底部４Ｂを有する。支持面４Ｓは、測色対象である繊維１０を支持する。繊維１０は、例えば毛束である。 The fiber holder 1 according to the first embodiment includes a support surface 4S, a bottom portion 4B, and a pair of protrusions 2a and 2b. Note that the support surface 4S and the bottom portion 4B constitute a support body. That is, the support body has a support surface 4S and a bottom portion 4B. The support surface 4S supports the fiber 10 that is the object of colorimetry. The fiber 10 is, for example, a hair bundle.

一対の突起２ａ、２ｂは、底部４Ｂに設けられている。一対の突起２ａ、２ｂは、互いに平行に延伸している。なお、突起２ａおよび突起２ｂは、図１（ａ）を参照して、底部４Ｂを縦断しているが、必ずしも、底部４Ｂを縦断しなくてもよい。例えば、繊維保持具１を平面視したときに（図１（ａ）参照）、突起２ａおよび突起２ｂの縦の長さが、底部４Ｂの縦の長さよりも短くてもよい。 A pair of protrusions 2a and 2b are provided on the bottom portion 4B. The pair of protrusions 2a and 2b extend parallel to each other. In addition, although the protrusion 2a and the protrusion 2b cross the bottom 4B vertically with reference to FIG. 1(a), they do not necessarily need to cross the bottom 4B vertically. For example, when the fiber holder 1 is viewed from above (see FIG. 1(a)), the vertical lengths of the protrusions 2a and 2b may be shorter than the vertical length of the bottom portion 4B.

なお、支持面４Ｓは、一対の突起２ａ、２ｂの間に配置されている。また、支持面４Ｓは、例えば、底部４Ｂの上に置かれた白色紙である。 Note that the support surface 4S is arranged between the pair of protrusions 2a and 2b. Further, the support surface 4S is, for example, white paper placed on the bottom portion 4B.

なお、波長450nm,550nmおよび650nmの光の支持面４Ｓにおける反射率は60％以上である。また、支持面４Ｓの視感反射率Yが60以上（ただし、光源はCIE標準光源D65であり、視野を10°とする）である。 Note that the reflectance of light with wavelengths of 450 nm, 550 nm, and 650 nm on the support surface 4S is 60% or more. Further, the luminous reflectance Y of the support surface 4S is 60 or more (provided that the light source is a CIE standard light source D65 and the field of view is 10°).

一対の突起２ａ、２ｂの底部４Ｂに対する高さｔ（以下、「一対の突起２ａ、２ｂの高さｔ」または「高さｔ」と記載することがある）は１ｍｍ以上３ｍｍ以下である。なお、支持面４Ｓの厚さは、一対の突起２ａ、２ｂの高さｔに比べて、無視できる程度に薄い（およそ0.1mm程度）。 The height t of the pair of protrusions 2a, 2b relative to the bottom 4B (hereinafter sometimes referred to as "height t of the pair of protrusions 2a, 2b" or "height t") is 1 mm or more and 3 mm or less. Note that the thickness of the support surface 4S is negligibly thin (approximately 0.1 mm) compared to the height t of the pair of protrusions 2a and 2b.

繊維１０は、一対の突起２ａ、２ｂの間に、一対の突起２ａ、２ｂの頂部２ａＴ、２ｂＴを超えないように配置される（図２（ｂ）参照）。 The fiber 10 is arranged between the pair of protrusions 2a, 2b so as not to exceed the tops 2aT, 2bT of the pair of protrusions 2a, 2b (see FIG. 2(b)).

一対の突起２ａ、２ｂの上部に透明部材８を配置している。透明部材８は、例えば、テンパックスガラスである。 A transparent member 8 is arranged above the pair of projections 2a and 2b. The transparent member 8 is, for example, Tempax glass.

次に、第一の実施形態にかかる繊維保持具１を用いた繊維１０の測色方法を説明する。 Next, a method for measuring the color of the fiber 10 using the fiber holder 1 according to the first embodiment will be described.

まず、繊維１０（例えば、毛束）を支持面４Ｓに支持させながら、一対の突起の間２ａ、２ｂに一対の突起２ａ、２ｂの頂部２ａＴ、２ｂＴを超えないように配置する。その後、透明部材８を、一対の突起２ａ、２ｂの頂部２ａＴ、２ｂＴに載せる（図２参照）。 First, the fiber 10 (for example, a hair bundle) is supported on the support surface 4S and placed between the pair of protrusions 2a, 2b so as not to exceed the tops 2aT, 2bT of the pair of protrusions 2a, 2b. Thereafter, the transparent member 8 is placed on the tops 2aT, 2bT of the pair of protrusions 2a, 2b (see FIG. 2).

さらに、図２に示すような状態で、繊維１０を測色する。測色は、透明部材８よりも上から測定光を繊維１０に向けて照射し、繊維１０から反射されてきた反射光を測定することにより行う。 Furthermore, the color of the fiber 10 is measured in a state as shown in FIG. Colorimetry is performed by irradiating measurement light toward the fibers 10 from above the transparent member 8 and measuring the reflected light reflected from the fibers 10.

なお、繊維１０として２種類の毛束（毛束１および毛束２）を選んで実験を行い、繊維１０を目視評価した結果に近い測色結果を、第一の実施形態にかかる繊維保持具１を用いた測色によって得られるか否かを検証した。 The experiment was conducted by selecting two types of hair bundles (hair bundle 1 and hair bundle 2) as the fibers 10, and the color measurement results close to the results of visual evaluation of the fibers 10 were obtained using the fiber holder according to the first embodiment. It was verified whether or not it could be obtained by colorimetry using 1.

（実験手順１）
まず、毛束１および毛束２を目視し、これらの色に合致した色見本１および色見本２を選定する。すると、毛束１の色に合致した色見本１は２９９Ｕ（おおむね青色に似た色）、毛束２の色に合致した色見本２は６０３Ｕ（おおむね黄色に似た色）となった。ただし、２９９Ｕおよび６０３Ｕは、SOLID CHIPS Uncoated THE PLUS SERIES / PANTONE（登録商標）の色見本である。 (Experiment procedure 1)
First, hair bundle 1 and hair bundle 2 are visually observed, and color sample 1 and color sample 2 that match these colors are selected. Then, the color sample 1 that matched the color of the hair bundle 1 was 299U (a color roughly similar to blue), and the color sample 2 that matched the color of the hair bundle 2 was 603U (a color roughly similar to yellow). However, 299U and 603U are color samples of SOLID CHIPS Uncoated THE PLUS SERIES/PANTONE (registered trademark).

（実験手順２）
次に、色見本および毛束を分光光度計で測定した。５回測定を行い、その結果を平均した。ただし、分光光度計は、CM-3600A / コニカミノルタを用いた。 (Experiment procedure 2)
Next, the color sample and hair tresses were measured with a spectrophotometer. Measurements were performed five times and the results were averaged. However, the spectrophotometer used was CM-3600A/Konica Minolta.

また、色見本は、開口径/測定径= 11mmφ/8mmφ、SCE（正反射光を除去した測定）、テンパックスガラス越しに測色を行った。ただし、合成紙を背景とした。 In addition, the color sample was measured using SCE (measurement that removed specular reflection light) using aperture diameter/measurement diameter = 11 mmφ/8 mmφ through Tempax glass. However, the background was synthetic paper.

また、毛束は、開口径/測定径= 30mmφ/25mmφ、SCEで測色を行った。ただし、第一の実施形態にかかる繊維保持具１を用いて繊維１０を測色した。ただし、高さｔを、１、２、３、４および５ｍｍにして、実験を行った。また、透明部材８として、テンパックスガラスを用いた。 Further, the color of the hair bundle was measured using SCE with opening diameter/measurement diameter = 30 mmφ/25 mmφ. However, the color of the fiber 10 was measured using the fiber holder 1 according to the first embodiment. However, experiments were conducted with the height t set to 1, 2, 3, 4, and 5 mm. Further, as the transparent member 8, Tempax glass was used.

（実験手順３）
色見本の測色結果と、毛束の測色結果との色差ΔE00（ただし、光源はCIE標準光源D65であり、視野を10°とする）を求め、ΔE00が５以下であれば、良好と評価した。ΔE00が５を超えれば、不良と評価した。 (Experiment procedure 3)
Calculate the color difference ΔE00 between the color measurement result of the color sample and the color measurement result of the hair bundle (however, the light source is CIE standard light source D65 and the field of view is 10°), and if ΔE00 is 5 or less, it is considered good. evaluated. If ΔE00 exceeded 5, it was evaluated as defective.

ただし、「良好」とは、繊維１０を目視評価した結果（すなわち、色見本の測色結果）に近い測色結果を、第一の実施形態にかかる繊維保持具１を用いた測色によって得られたことを意味する。 However, "good" means that a color measurement result close to the result of visually evaluating the fiber 10 (i.e., a color measurement result of a color sample) was obtained by color measurement using the fiber holder 1 according to the first embodiment. It means that it was given.

一方、「不良」とは、繊維１０を目視評価した結果（すなわち、色見本の測色結果）に近い測色結果を、第一の実施形態にかかる繊維保持具１を用いた測色によって得られなかったことを意味する。 On the other hand, "defective" means that a color measurement result close to the result of visually evaluating the fiber 10 (i.e., a color measurement result of a color sample) was obtained by color measurement using the fiber holder 1 according to the first embodiment. It means that it was not possible.

表１は、毛束１に関する実験結果を示す。なお、色見本１および毛束１の測色結果をＬ＊ａ＊ｂ＊座標系で示した。 Table 1 shows the experimental results for hair bundle 1. Note that the color measurement results for color sample 1 and hair bundle 1 are shown in the L*a*b* coordinate system.

表２は、毛束２に関する実験結果を示す。なお、色見本２および毛束２の測色結果をＬ＊ａ＊ｂ＊座標系で示した。
Figure 0007397136000002
Table 2 shows the experimental results for hair bundle 2. Note that the color measurement results of color sample 2 and hair bundle 2 are shown in the L*a*b* coordinate system.

Figure 0007397136000003

毛束１および毛束２の実験結果により、高さｔが１ｍｍ以上３ｍｍ以下である場合が、良好であることが分かる。
Figure 0007397136000003
The experimental results for hair bundle 1 and hair bundle 2 show that the height t is good when it is 1 mm or more and 3 mm or less.

高さｔが３ｍｍを超えると、毛束１および毛束２が厚すぎて、測定光が毛束１および毛束２の内部を通って外に逃げてしまうエッジロスエラーにより、反射光が暗くなり過ぎてしまう。また、高さｔを１ｍｍ未満とすることは、毛束１および毛束２の体積からして難しい。よって、上記のように、高さｔが１ｍｍ以上３ｍｍ以下である場合が良好となる。 If the height t exceeds 3 mm, the hair bundles 1 and 2 are too thick, and the reflected light becomes dark due to an edge loss error in which the measurement light passes through the inside of the hair bundles 1 and 2 and escapes to the outside. It becomes too much. Furthermore, it is difficult to make the height t less than 1 mm because of the volumes of the hair bundles 1 and 2. Therefore, as described above, the height t is preferably 1 mm or more and 3 mm or less.

また、比較例として、第一の実施形態にかかる繊維保持具１から支持面４Ｓを除去したものにつき、高さｔ＝１、２ｍｍで実験した結果を示す。表３は、毛束１に関する実験結果を示す。表４は、毛束２に関する実験結果を示す。 Moreover, as a comparative example, the results of an experiment at heights t=1 and 2 mm are shown for the fiber holder 1 according to the first embodiment with the support surface 4S removed. Table 3 shows the experimental results for hair bundle 1. Table 4 shows the experimental results for hair bundle 2.

Figure 0007397136000005

毛束１にせよ毛束２にせよ支持面４Ｓが無い場合は、不良である。
Figure 0007397136000005
If either the hair bundle 1 or the hair bundle 2 does not have the support surface 4S, it is defective.

これは、支持面４Ｓ（例えば、白色紙）があることにより、測定光が支持面４Ｓにより反射され、反射光が明るくなることを意味する。支持面４Ｓが無ければ、測定光の反射が少なくなり、反射光が暗くなり過ぎてしまう。よって、支持面４Ｓがある場合が良好となる。 This means that due to the presence of the support surface 4S (for example, white paper), the measurement light is reflected by the support surface 4S, and the reflected light becomes brighter. Without the support surface 4S, the measurement light would be reflected less and the reflected light would be too dark. Therefore, it is better when the support surface 4S is present.

第一の実施形態にかかる繊維保持具１によれば、高さｔが１ｍｍ以上３ｍｍ以下とし、しかも、支持面４Ｓを設けたことにより、繊維１０を測色して、繊維１０を目視評価した結果に近い測色結果を得ることができる。 According to the fiber holder 1 according to the first embodiment, the height t is 1 mm or more and 3 mm or less, and the supporting surface 4S is provided, so that the fiber 10 can be visually evaluated by color measurement. It is possible to obtain color measurement results that are close to the actual results.

第二の実施形態
第二の実施形態にかかる繊維保持具１は、一対の突起２ａ、２ｂの支持体の底部４Ｂに対する高さｔが１ｍｍ以上２ｍｍ以下である点が、第一の実施形態にかかる繊維保持具１（高さｔが１ｍｍ以上３ｍｍ以下である）と異なる。 Second Embodiment The fiber holder 1 according to the second embodiment is different from the first embodiment in that the height t of the pair of protrusions 2a and 2b relative to the bottom 4B of the support is 1 mm or more and 2 mm or less. This is different from such a fiber holder 1 (height t is 1 mm or more and 3 mm or less).

第一の実施形態において説明したように、繊維１０として毛束１（おおむね青色に似た色）および毛束２（おおむね黄色に似た色）を選んだ場合は、高さｔが１ｍｍ以上３ｍｍ以下であると、繊維１０を目視評価した結果に近い測色結果を得ることができる。すなわち、繊維１０の色を適切に選べば、高さｔが１ｍｍ以上３ｍｍ以下であれば良好な評価が得られる。 As explained in the first embodiment, when hair bundle 1 (color roughly similar to blue) and hair bundle 2 (color roughly similar to yellow) are selected as the fibers 10, the height t is 1 mm or more and 3 mm. If it is below, it is possible to obtain a colorimetric result close to the result of visual evaluation of the fiber 10. That is, if the color of the fiber 10 is appropriately selected, a good evaluation can be obtained if the height t is 1 mm or more and 3 mm or less.

しかし、繊維１０として選んだ色によっては、高さｔが１ｍｍ以上２ｍｍ以下でないと、繊維１０を目視評価した結果に近い測色結果を得られない。この場合を、第二の実施形態として説明する。すなわち、繊維１０の色を限定しないのであれば、高さｔが１ｍｍ以上２ｍｍ以下でなければならない。 However, depending on the color selected as the fiber 10, unless the height t is 1 mm or more and 2 mm or less, colorimetric results close to the results of visual evaluation of the fiber 10 cannot be obtained. This case will be described as a second embodiment. That is, if the color of the fiber 10 is not limited, the height t must be 1 mm or more and 2 mm or less.

第二の実施形態にかかる繊維保持具１は、高さｔが１ｍｍ以上２ｍｍ以下であることを除けば、第一の実施形態にかかる繊維保持具１と同様である。 The fiber holder 1 according to the second embodiment is the same as the fiber holder 1 according to the first embodiment, except that the height t is 1 mm or more and 2 mm or less.

また、第二の実施形態にかかる繊維保持具１を用いた繊維１０の測色方法は、第一の実施形態にかかる繊維保持具１を用いた繊維１０の測色方法と同様である。 Further, the method for measuring the color of the fiber 10 using the fiber holder 1 according to the second embodiment is the same as the method for measuring the color of the fiber 10 using the fiber holder 1 according to the first embodiment.

なお、繊維１０として３種類の毛束（毛束３、毛束４および毛束５）を選んで実験を行い、繊維１０を目視評価した結果に近い測色結果を、第二の実施形態にかかる繊維保持具１を用いた測色によって得られるか否かを検証した。 In addition, an experiment was conducted by selecting three types of hair bundles (hair bundle 3, hair bundle 4, and hair bundle 5) as the fiber 10, and color measurement results close to the results of visual evaluation of the fiber 10 were used in the second embodiment. It was verified whether or not it could be obtained by colorimetry using such a fiber holder 1.

First, hair bundle 3, hair bundle 4, and hair bundle 5 are visually observed, and color sample 3, color sample 4, and color sample 5 that match these colors are selected. Then, color sample 3 that matches the color of hair bundle 3 is J25-70A (a color roughly similar to gray), color sample 4 that matches the color of hair bundle 4 is 3252U (a color roughly similar to green), hair bundle Color sample 5 that matched color 5 was 673U (a color roughly similar to pink).

ただし、Ｊ２５－７０Ａは2017年J版塗料用標準色（ポケット版）/ 日本塗料工業会の色見本であり、３２５２Ｕおよび６７３Ｕは、SOLID CHIPS Uncoated THE PLUS SERIES / PANTONE（登録商標）の色見本である。 However, J25-70A is a color sample from the 2017 J Edition Paint Standard Colors (Pocket Edition) / Japan Paint Manufacturers Association, and 3252U and 673U are color samples from SOLID CHIPS Uncoated THE PLUS SERIES / PANTONE (registered trademark). be.
