Abstract
Description
本発明は、赤外線吸収性繊維、編織物、又は不織布に関する。 The present invention relates to infrared absorbing fibers, knitted fabrics, or nonwoven fabrics.
光を吸収して発熱する性質を有する繊維製品は、公知である。例えば、カーボンブラック等の赤外線吸収性顔料は、赤外線を吸収して発熱する性質を有するため、これを繊維に練り込み、又は塗布することにより、発熱性繊維が得られる。 Textile products that have the property of absorbing light and generating heat are known. For example, infrared absorbing pigments such as carbon black have the property of absorbing infrared rays and generating heat, and therefore, heat-generating fibers can be obtained by kneading or coating this into fibers.
しかし、赤外線吸収性顔料としてカーボンブラックを含む繊維は、カーボンブラックの黒色のために色調が極端に暗くなって、明るい色調の意匠を適用できない問題がある。 However, fibers containing carbon black as an infrared absorbing pigment have a problem in that the color tone becomes extremely dark due to the black color of carbon black, making it impossible to apply designs with bright colors.
この点、特許文献１には、赤外線吸収性顔料として、Ｃｓ０．３３ＷＯ３に代表される複合タングステン酸化物微粒子を含有する繊維であって、当該微粒子の含有量が当該繊維の固形分に対して、０．００１～８０重量％である赤外線吸収性繊維が記載されている。 In this regard, Patent Document 1 describes a fiber containing composite tungsten oxide fine particles typified by Cs 0.33 WO 3 as an infrared absorbing pigment, and in which the content of the fine particles is less than the solid content of the fiber. On the other hand, infrared absorbing fibers having a content of 0.001 to 80% by weight are described.
複合タングステン酸化物は、カーボンブラックの黒色と比較すると、色調が明るい。そのため、複合タングステン酸化物含有の繊維製品は、カーボンブラック含有の繊維製品に比べて、意匠面での自由度が大きい利点を有する。 Composite tungsten oxide has a brighter color than the black color of carbon black. Therefore, fiber products containing composite tungsten oxide have the advantage of greater freedom in design than fiber products containing carbon black.
複合タングステン酸化物、例えばＣｓ０．３３ＷＯ３（以下、ＣｓＷＯという）は、可視光下で視認可能な淡青緑色を呈し、明るい色調の繊維製品に適用した場合には、得られる繊維製品の色調が変更される場合がある。 Composite tungsten oxide, such as Cs 0.33 WO 3 (hereinafter referred to as CsWO), exhibits a light bluish-green color that is visible under visible light, and when applied to bright-toned textile products, the color tone of the resulting textile product changes. may change.
一般に、発熱性の防寒衣料では、衣料の全部を発熱性繊維製品で構成する必要はなく、衣料のうちの、発熱が防寒性に寄与する程度の大きい部分のみに発熱性繊維製品を用い、他の部分は通常の繊維製品で構成される。このとき、発熱性繊維製品として、ＣｓＷＯを含む繊維製品と用いると、ＣｓＷＯを含む部分と、ＣｓＷＯを含まない部分とで色調の差が生じ、意匠上の問題が生じる場合がある。この傾向は、目的の衣料の色調が特に明るい場合に顕著である。 In general, heat-generating cold-weather clothing does not need to be made entirely of heat-generating textiles; instead, heat-generating textiles are used only in the parts of the clothing where heat generation contributes to cold protection, and other The section consists of ordinary textile products. At this time, if a textile product containing CsWO is used as a heat-generating textile product, a difference in color tone may occur between the part containing CsWO and the part not containing CsWO, which may cause problems in terms of design. This tendency is remarkable when the color tone of the target clothing is particularly bright.
また、特許文献１によると、赤外線吸収性繊維中のＣｓＷＯ含有量として、当該繊維の固形分に対して０．００１～８０重量％と、無闇に広い範囲が提示されており、防寒衣料としたときの発熱性が不十分な場合、及び過剰な場合を包含している。 Furthermore, according to Patent Document 1, the CsWO content in infrared absorbing fibers is presented in a wide range from 0.001 to 80% by weight based on the solid content of the fibers, and is used as cold weather clothing. This includes cases where the exothermic property is insufficient and cases where the exothermic property is excessive.
本発明は、上記の事情に鑑みてなされたものである。したがって、本発明の目的は、赤外線吸収性顔料を含有し、赤外線を吸収して発熱する性質を有する繊維、編織物、又は不織布であって、防寒衣料等の衣料品に適用したときに、好ましい意匠性を提供することができる、繊維、編織物、又は不織布を提供することである。 The present invention has been made in view of the above circumstances. Therefore, an object of the present invention is to provide fibers, knitted fabrics, or nonwoven fabrics containing infrared absorbing pigments and having the property of absorbing infrared rays and generating heat, which are preferable when applied to clothing such as winter clothing. An object of the present invention is to provide fibers, knitted fabrics, or nonwoven fabrics that can provide design properties.

The term "nonwoven fabric" refers to a sheet-like material made of intertwined fibers, and does not include woven or knitted fabrics. Hereinafter, fibers, knitted fabrics, and nonwoven fabrics may be collectively referred to as "textile products."
本明細書においては、また、赤外線吸収性繊維製品の、ＣＩＥ１９７６色空間におけるＬ＊が３０以上であることを「Ｌ＊要件」ということがあり、赤外線吸収性繊維製品と、該赤外線吸収性繊維製品が前記赤外線吸収性顔料を含まないときとの、ＣＩＥ１９７６色空間における色差ΔＥが１０以下であることを「ΔＥ要件」ということがある。 In this specification, an infrared absorbing fiber product having an L * of 30 or more in the CIE 1976 color space is sometimes referred to as an "L * requirement", and the infrared absorbing fiber product and the infrared absorbing fiber A color difference ΔE of 10 or less in the CIE 1976 color space compared to when the product does not contain the infrared absorbing pigment is sometimes referred to as "ΔE requirement".

In order to solve the problems of the present invention, the present inventors
The color tone of textile products without infrared absorbing pigments,
The amount of infrared absorbing pigment contained in the infrared absorbing textile product,
Changes in color tone of textile products when containing a predetermined amount of infrared absorbing pigment;
The relationship between the heat generation properties of textile products and the presence of a predetermined amount of infrared absorbing pigment was investigated in detail.
その結果、以下のことが分かった：
（１）暗い色調の繊維製品では、赤外線吸収性顔料を含まないときと、含むときとの繊維製品の色調の変化が、そもそも問題にならないほど小さいこと、
（２）明るい色調の繊維製品のうち、特に明るい色では、彩度の小さい繊維製品の方が、彩度の大きい色鮮やかな繊維製品よりも、赤外線吸収性顔料を含むことによる色調の変化を目視で識別し易いこと、及び
（３）明るい色調の繊維製品が、色調の変化を識別し難い範囲で赤外線吸収性顔料を含むことによって、防寒衣料として快適な発熱性を発揮すること。
As a result, we found the following:
(1) In the case of dark-colored textile products, the change in color of the textile product between when it does not contain an infrared absorbing pigment and when it does contain an infrared absorbing pigment is so small that it does not pose a problem in the first place;
(2) Among brightly colored textile products, especially in bright colors, textile products with low saturation are more susceptible to changes in color tone due to the inclusion of infrared absorbing pigments than textile products with bright colors with high saturation. (3) The brightly colored textile products contain infrared absorbing pigments in a range where it is difficult to discern changes in color tone, thereby exhibiting heat generating properties that are comfortable for cold-weather clothing.
本発明は、以上の知見に基づいてなされたものである。 The present invention has been made based on the above findings.
本発明の赤外線吸収性繊維製品において、ＣＩＥ１９７６色空間におけるＬ＊が３０以上である場合、有意の量の赤外線吸収性顔料を含むことによって、色調の変化が問題になり得る程度に、繊維製品の色調が明るい。したがって、有意の量の赤外線吸収性顔料を含んでいても、色調の変化が識別し難い、Ｌ＊が３０未満の暗い色調の繊維製品は、本発明の範囲から除外される。 In the infrared-absorbing textile product of the present invention, if L * in the CIE 1976 color space is 30 or more, the inclusion of a significant amount of infrared-absorbing pigment may cause the textile product to change to the extent that color tone change may become a problem. Bright colors. Therefore, dark-toned textile products with an L * of less than 30, which contain significant amounts of infrared-absorbing pigments but have difficult to discern changes in tone, are excluded from the scope of the present invention.
本発明の赤外線吸収性繊維製品において、赤外線吸収性顔料を含むときと、含まないときとの、ＣＩＥ１９７６色空間における色差ΔＥが１０以下であるとは、当該繊維製品が、色調の変化を識別し難い範囲で赤外線吸収性顔料を含んでいることを示す。この要件を満たす繊維製品は、防寒衣料として快適な発熱性を有することができるのに併せて、赤外線吸収性顔料を含有しない部分との色調の差を小さくし、それによって好ましい意匠性を発揮することができる。 In the infrared absorbing textile product of the present invention, a color difference ΔE of 10 or less in the CIE 1976 color space between when the infrared absorbing pigment is included and when it is not included means that the textile product can discriminate changes in color tone. Indicates that it contains infrared absorbing pigments to a certain extent. Textile products that meet this requirement not only have heat generation properties that are comfortable for cold-weather clothing, but also reduce the difference in color tone between areas that do not contain infrared absorbing pigments, thereby exhibiting desirable design properties. be able to.
本発明の赤外線吸収性繊維製品の色調の明るさが特に大きい場合には、赤外線吸収性顔料を含むことによって、繊維製品の色調の変化を目視で識別し易くなっている。このことに鑑みると、繊維製品の色調の明るさが特に大きい場合には、彩度が大きい方が、色調の変化の目視による識別を困難化する観点から有利である。したがって、本発明の赤外線吸収性繊維製品の明るさが特に大きい場合、例えば、ＣＩＥ１９７６色空間におけるＬ＊が９０超である場合には、下記の要件（ｉ）～（ｉｖ）：
（ｉ）ＣＩＥ１９７６色空間におけるａ＊が－１０以下であること、
（ｉｉ）ＣＩＥ１９７６色空間におけるａ＊が１０以上であること、
（ｉｉｉ）ＣＩＥ１９７６色空間におけるｂ＊が－１０以下であること、及び
（ｉｖ）ＣＩＥ１９７６色空間におけるｂ＊が１０以上であること
のうちの少なくとも１つを満たすことが好ましい。
When the infrared absorbing textile product of the present invention has a particularly bright color tone, the inclusion of an infrared absorbing pigment makes it easier to visually identify changes in the color tone of the textile product. In view of this, when the brightness of the color tone of the textile product is particularly high, it is advantageous to have a higher chroma from the viewpoint of making it difficult to visually identify changes in color tone. Therefore, if the infrared absorbing textile product of the present invention has particularly high brightness, for example, if L * in the CIE 1976 color space exceeds 90, the following requirements (i) to (iv):
(i) a * in CIE1976 color space is -10 or less;
(ii) a * in the CIE 1976 color space is 10 or more;

《赤外線吸収性繊維製品》
本発明の赤外線吸収性繊維製品は、
赤外線吸収性顔料を含む赤外線吸収性繊維製品であって、
ＣＩＥ１９７６色空間におけるＬ＊が３０以上であり、かつ、

《Infrared absorbing textile products》
The infrared absorbing fiber product of the present invention is
An infrared absorbing textile product containing an infrared absorbing pigment,
L * in CIE1976 color space is 30 or more, and

本発明の赤外線吸収性繊維製品は、
ＣＩＥ１９７６色空間におけるＬ＊が９０超であり、かつ、下記（ｉ）～（ｉｖ）のうちの少なくとも１つを満たす、赤外線吸収性繊維製品であってもよい：
（ｉ）ＣＩＥ１９７６色空間におけるａ＊が－１０以下であること、
（ｉｉ）ＣＩＥ１９７６色空間におけるａ＊が１０以上であること、
（ｉｉｉ）ＣＩＥ１９７６色空間におけるｂ＊が－１０以下であること、及び
（ｉｖ）ＣＩＥ１９７６色空間におけるｂ＊が１０以上であること。
The infrared absorbing fiber product of the present invention is
It may be an infrared absorbing textile product that has L * in the CIE 1976 color space of more than 90 and satisfies at least one of the following (i) to (iv):
(i) a * in CIE1976 color space is -10 or less;
(ii) a * in the CIE 1976 color space is 10 or more;
(iii) b * in the CIE 1976 color space is -10 or less; and (iv) b * in the CIE 1976 color space is 10 or more.
本発明の赤外線吸収性繊維製品は、或いは、
ＣＩＥ１９７６色空間におけるＬ＊が９０以下である、
赤外線吸収性繊維製品であってもよい。
The infrared absorbing fiber product of the present invention, or
L * in CIE1976 color space is 90 or less,
It may also be an infrared absorbing textile product.
赤外線吸収性繊維製品と、赤外線吸収性繊維製品が前記赤外線吸収性顔料を含まないときとの、ＣＩＥ１９７６色空間における色差ΔＥは、１０以下である。両者間のΔＥが１０以下であれば、繊維製品が赤外線吸収性顔料を含むことによる色調の変化を、目視で識別することが困難となる。ΔＥの値は、９以下、８以下、６以下、５以下、又は４以下であってもよい。また、ΔＥの値は、０以上、０超、０．５以上、１以上、２以上、又は３以上であってよい。 The color difference ΔE in the CIE 1976 color space between the infrared absorbing textile product and when the infrared absorbing textile product does not contain the infrared absorbing pigment is 10 or less. If the ΔE between the two is 10 or less, it will be difficult to visually identify the change in color tone due to the inclusion of the infrared absorbing pigment in the textile product. The value of ΔE may be 9 or less, 8 or less, 6 or less, 5 or less, or 4 or less. Further, the value of ΔE may be 0 or more, more than 0, 0.5 or more, 1 or more, 2 or more, or 3 or more.
赤外線吸収性繊維製品において、ＣＩＥ１９７６色空間におけるＬ＊が９０超であるとき、すなわち、繊維製品の色調が特に明るいときであっても、上記（ｉ）～（ｉｖ）のうちの少なくとも１つを満たせば、繊維製品が赤外線吸収性顔料を含むことによる色調の変化を、目視で識別することを困難とすることができる。Ｌ＊が９０超であるとき、色調変化の目視識別をより困難にする観点から、色差ΔＥは、５以下、４．５以下、４以下、３．５以下、又は３以下であってよく、０以上、０超、０．１以上、０．２以上、０．３以上、０．４以上、又は０．５以上であってよい。 In an infrared absorbing textile product, when L * in the CIE 1976 color space is over 90, that is, even when the color tone of the textile product is particularly bright, at least one of the above (i) to (iv) is applied. If the requirements are met, it will be difficult to visually discern changes in color tone due to the inclusion of infrared absorbing pigments in textile products. When L * is more than 90, the color difference ΔE may be 5 or less, 4.5 or less, 4 or less, 3.5 or less, or 3 or less, from the viewpoint of making visual identification of color tone changes more difficult. It may be 0 or more, more than 0, 0.1 or more, 0.2 or more, 0.3 or more, 0.4 or more, or 0.5 or more.
しかしながら、Ｌ＊が９０超であるとき、色調変化の目視識別の困難性を確実にしようとすると、当該繊維製品中の赤外線吸収性顔料の含有量が制限され、発熱性が制限されることがある。この観点からは、赤外線吸収性繊維製品のＣＩＥ１９７６色空間におけるＬ＊は、９０以下であってよい。 However, when L * is more than 90, the content of infrared absorbing pigment in the textile product may be limited and the heat generation property may be limited in order to ensure the difficulty of visual identification of color change. be. From this point of view, L * in the CIE 1976 color space of the infrared absorbing textile product may be 90 or less.
このＬ＊は、繊維製品の所望の色調に応じて、上述の範囲で適宜に設定されており、例えば、赤系統の色調を有する繊維製品の場合、Ｌ＊は、９０以下であり、８０以下、７０以下、６０以下、又は５０以下であってよい。黄系統の色調を有する繊維製品の場合、Ｌ＊は、９０以下であり、８９以下、８８以下、８７以下、又は８６以下であってよい。青系統の色調を有する繊維製品の場合、Ｌ＊は、９０以下であり、８０以下、６０以下、又は４０以下であってよい。 This L * is appropriately set within the above range depending on the desired color tone of the textile product. For example, in the case of a textile product with a red color tone, L * is 90 or less, and 80 or less. , 70 or less, 60 or less, or 50 or less. In the case of textile products with yellowish tones, L * is 90 or less, and may be 89 or less, 88 or less, 87 or less, or 86 or less. For textile products with blue-based tones, L * is 90 or less, and may be 80 or less, 60 or less, or 40 or less.
Ｌ＊が９０以下であっても、繊維製品の色調が比較的明るいとき、例えば、Ｌ＊が８０超のときには、色調変化の目視識別の困難性を確実にするためには、色差ΔＥを、８以下、７以下、６以下、又は５以下としてよい。一方、Ｌ＊が８０以下のときには、色差ΔＥが１０以下であれば、色調変化の目視識別は極めて困難となる。 Even if L * is 90 or less, when the color tone of the textile product is relatively bright, for example, when L * is greater than 80, in order to ensure the difficulty of visual identification of color tone changes, the color difference ΔE must be It may be 8 or less, 7 or less, 6 or less, or 5 or less. On the other hand, when L * is 80 or less and the color difference ΔE is 10 or less, visual identification of color tone changes becomes extremely difficult.

Examples of such infrared absorbing pigments include:
General formula M x W y O z (1)

Composite tungsten oxide represented by
General formula W y O z (2)
{In formula (2), W is tungsten, O is oxygen, y and z are each positive numbers, and 2.45≦z/y≦2.999}
Examples include tungsten oxide having a Magneli phase represented by the following, and one or more selected from these may be appropriately selected and used.
ここで、アルカリ金属元素とは、水素原子を除く周期律表第１族元素である。アルカリ土類金属元素とは、Ｂｅ及びＭｇを除く周期律表第２族元素である。希土類元素とは、Ｓｃ、Ｙ、及びタンタノイド元素である。 Here, the alkali metal elements are Group 1 elements of the periodic table excluding hydrogen atoms. The alkaline earth metal elements are Group 2 elements of the periodic table excluding Be and Mg. Rare earth elements are Sc, Y, and tanthanoid elements.
一般式（１）で表される複合タングステン酸化物は、元素Ｍを含む。そのため、自由電子が生成され、この自由電子由来の吸収帯が近赤外波長領域に発現されるため、波長１，０００ｎｍ付近の近赤外線を吸収して発熱する材料として、好適である。 The composite tungsten oxide represented by general formula (1) contains element M. Therefore, free electrons are generated and an absorption band derived from the free electrons is expressed in the near-infrared wavelength region, so it is suitable as a material that absorbs near-infrared rays with a wavelength of around 1,000 nm and generates heat.
元素Ｍの添加量を示すｘ／ｙの値が０超であれば、十分な量の自由電子が生成され近赤外線吸収効果を十分に得ることができる。元素Ｍの添加量が多いほど、自由電子の供給量が増加し、近赤外線吸収効果も上昇するが、ｘ／ｙの値が１程度で飽和する。ｘ／ｙの値が１以下であれば、微粒子含有層中における不純物相の生成を回避できるので好ましい。ｘ／ｙの値は、０．００１以上、０．２以上又は０．３０以上であることが好ましく、この値は、０．８５以下、０．５以下又は０．３５以下であることが好ましい。ｘ／ｙの値は、理想的には０．３３である。 If the value of x/y indicating the amount of addition of element M exceeds 0, a sufficient amount of free electrons will be generated and a sufficient near-infrared absorption effect can be obtained. As the amount of element M added increases, the amount of free electrons supplied increases and the near-infrared absorption effect also increases, but the value of x/y becomes saturated at about 1. It is preferable that the value of x/y is 1 or less because it is possible to avoid the formation of impurity phases in the fine particle-containing layer. The value of x/y is preferably 0.001 or more, 0.2 or more, or 0.30 or more, and this value is preferably 0.85 or less, 0.5 or less, or 0.35 or less. . The value of x/y is ideally 0.33.
特に、一般式（１）における元素Ｍが、Ｃｓ、Ｒｂ、Ｋ、Ｔｌ、Ｉｎ、Ｂａ、Ｌｉ、Ｃａ、Ｓｒ、Ｆｅ、及びＳｎのうちの１種以上である場合、近赤外線吸収性材料としての光学特性、及び耐候性が向上する観点から好ましく、ＭがＣｓである場合、特に好ましい。 In particular, when the element M in general formula (1) is one or more of Cs, Rb, K, Tl, In, Ba, Li, Ca, Sr, Fe, and Sn, the material can be used as a near-infrared absorbing material. It is preferable from the viewpoint of improving optical properties and weather resistance, and it is particularly preferable when M is Cs.
ＣｓｘＷｙＯｚ（０．２５≦ｘ／ｙ≦０．３５、２．２≦ｚ／Ｙ≦３．０）の場合には、格子定数が、ａ軸は７．４０６０Å以上７．４０８２Å以下、かつｃ軸は７．６１０６Å以上７．６１４９Å以下であることが、近赤外領域の光学特性及び耐候性の面から好ましい。 In the case of Cs x W y O z (0.25≦x/y≦0.35, 2.2≦z/Y≦3.0), the lattice constant is 7.4060 Å or more and 7.4082 Å for the a-axis. From the viewpoint of optical properties in the near-infrared region and weather resistance, it is preferable that the c-axis is 7.6106 Å or more and 7.6149 Å or less.
一般式（１）で表される複合タングステン酸化物は、六方晶の結晶構造を有するか、又は六方晶の結晶構造から成るとき、赤外線吸収性材料微粒子の可視光波長領域の透過が向上し、かつ近赤外光波長領域の吸収が向上するので好ましい。六方晶の空隙に元素Ｍの陽イオンが添加されて存在するとき、可視光波長領域の透過が向上し、近赤外光波長領域の吸収が向上する。ここで、一般には、イオン半径の大きな元素Ｍを添加したときに、六方晶が形成される。具体的には、Ｃｓ、Ｒｂ、Ｋ、Ｔｌ、Ｉｎ、Ｂａ、Ｓｎ、Ｌｉ、Ｃａ、Ｓｒ、Ｆｅ等のイオン半径の大きい元素を添加したときに、六方晶が形成され易い。しかしながら、これらの元素に限定されるものではなく、これらの元素以外の元素でも、ＷＯ６単位で形成される六角形の空隙に添加元素Ｍが存在すればよい。 When the composite tungsten oxide represented by the general formula (1) has a hexagonal crystal structure or consists of a hexagonal crystal structure, the transmission of the infrared absorbing material fine particles in the visible wavelength region is improved, Moreover, absorption in the near-infrared wavelength region is improved, which is preferable. When cations of element M are added and present in the voids of the hexagonal crystal, transmission in the visible wavelength region is improved and absorption in the near-infrared wavelength region is improved. Generally, when an element M having a large ionic radius is added, hexagonal crystals are formed. Specifically, when an element with a large ionic radius such as Cs, Rb, K, Tl, In, Ba, Sn, Li, Ca, Sr, or Fe is added, hexagonal crystals are likely to be formed. However, the present invention is not limited to these elements, and any element other than these elements may be used as long as the additive element M is present in the hexagonal void formed by 6 units of WO.
六方晶の結晶構造を有する複合タングステン酸化物が均一な結晶構造を有するとき、添加元素Ｍの添加量は、ｘ／ｙの値で０．２以上０．５以下が好ましく、より好ましくは０．３０以上０．３５以下であり、理想的には０．３３である。ｘ／ｙの値が０．３３となることにより、添加元素Ｍが、六角形の空隙のすべてに配置されると考えられる。 When the composite tungsten oxide having a hexagonal crystal structure has a uniform crystal structure, the amount of the additive element M added is preferably 0.2 or more and 0.5 or less in x/y value, more preferably 0. It is 30 or more and 0.35 or less, and ideally 0.33. Since the value of x/y is 0.33, it is considered that the additive element M is arranged in all the hexagonal voids.
一般式（１）で表される複合タングステン酸化物が、シランカップリング剤で処理されていると、分散性、近赤外線吸収性及び可視光波長領域における透明性に優れるので好ましい。 It is preferable that the composite tungsten oxide represented by the general formula (1) is treated with a silane coupling agent because it has excellent dispersibility, near-infrared absorption, and transparency in the visible wavelength region.
一般式（２）で表されるマグネリ相を有するタングステン酸化物において、ｚ／ｙの値が２．４５≦ｚ／ｙ≦２．９９９の関係を満たす組成比を有する所謂「マグネリ相」は、化学的に安定であり、近赤外光波長領域の吸収特性も良いので、近赤外線吸収材料として好ましい。 In a tungsten oxide having a Magneli phase represented by the general formula (2), the so-called "Magneli phase" having a composition ratio where the value of z/y satisfies the relationship of 2.45≦z/y≦2.999 is: It is chemically stable and has good absorption characteristics in the near-infrared wavelength region, so it is preferred as a near-infrared absorbing material.
一般式（１）及び（２）において、ｚ／ｙの値は、酸素量の制御の水準を示す。一般式（１）で表される複合タングステン酸化物は、ｚ／ｙの値が２．２≦ｚ／ｙ≦３．０の関係を満たすので、一般式（２）で表されるタングステン酸化物と同じ酸素制御機構が働くことに加えて、ｚ／ｙ＝３．０の場合でさえも元素Ｍの添加による自由電子の供給がある。一般式（１）において、ｚ／ｙの値が２．４５≦ｚ／ｙ≦３．０の関係を満たすことがより好ましい。 In general formulas (1) and (2), the value of z/y indicates the level of control of the amount of oxygen. The composite tungsten oxide represented by the general formula (1) has a z/y value that satisfies the relationship 2.2≦z/y≦3.0, so the tungsten oxide represented by the general formula (2) In addition to the same oxygen control mechanism working, there is a supply of free electrons due to the addition of element M even in the case of z/y = 3.0. In general formula (1), it is more preferable that the value of z/y satisfies the relationship of 2.45≦z/y≦3.0.
なお、本発明における複合タングステン酸化物及びタングステン酸化物の製造時に使用する原料化合物に由来して、当該複合タングステン酸化物及びタングステン酸化物を構成する酸素原子の一部が、ハロゲン原子に置換されている場合がある。しかし、このことは、本発明の実施において問題はない。そこで、本発明における複合タングステン酸化物及びタングステン酸化物には、酸素原子の一部がハロゲン原子に置換している場合も含まれる。 Note that some of the oxygen atoms constituting the composite tungsten oxide and tungsten oxide in the present invention are substituted with halogen atoms, originating from the raw material compound used during the production of the composite tungsten oxide and tungsten oxide. There may be cases. However, this is not a problem in implementing the present invention. Therefore, the composite tungsten oxide and tungsten oxide in the present invention include cases where some of the oxygen atoms are replaced with halogen atoms.
本発明における赤外線吸収性顔料は、近赤外光波長領域、特に波長１，０００ｎｍ付近の光を大きく吸収するため、その透過色調が青色系から緑色系となる場合が多い。しかしながらこの発色は淡いため、当該赤外線吸収性顔料を含む本発明の赤外線吸収性繊維製品は、防寒衣料等の衣料品に適用したときに、好ましい意匠性を提供することができる。 The infrared absorbing pigment of the present invention largely absorbs light in the near-infrared wavelength region, particularly around a wavelength of 1,000 nm, so its transmitted color tone often ranges from blue to green. However, since this color development is pale, the infrared absorbing textile product of the present invention containing the infrared absorbing pigment can provide a desirable design when applied to clothing such as winter clothing.
本発明の赤外線吸収性繊維製品における赤外線吸収性顔料の含有量については、後述する。 The content of the infrared absorbing pigment in the infrared absorbing fiber product of the present invention will be described later.

〈赤外線吸収性編織物又は不織布〉
本発明の赤外線吸収性繊維製品は、赤外線吸収性編織物又は不織布を包含する。以下、編織物と不織布とをまとめて、「編織物等」ということがある。
<Infrared absorbing knitted fabric or nonwoven fabric>
The infrared absorbing textile products of the present invention include infrared absorbing knitted fabrics or nonwoven fabrics. Hereinafter, knitted fabrics and nonwoven fabrics may be collectively referred to as "knitted fabrics, etc.".
本発明の赤外線吸収性編織物等は、
赤外線吸収性顔料を含む赤外線吸収性編織物等であって、
ＣＩＥ１９７６色空間におけるＬ＊が３０以上であり、かつ、
赤外線吸収性編織物等と、当該赤外線吸収性編織物等が赤外線吸収性顔料を含まないときとの、ＣＩＥ１９７６色空間における色差ΔＥが１０以下である。
The infrared absorbing knitted fabric of the present invention, etc.
An infrared absorbing knitted fabric etc. containing an infrared absorbing pigment,
L * in CIE1976 color space is 30 or more, and
The color difference ΔE in the CIE 1976 color space between the infrared absorbing knitted fabric, etc. and the case where the infrared absorbing knitted fabric, etc. does not contain an infrared absorbing pigment is 10 or less.
本発明の赤外線吸収性編織物等における赤外線吸収性顔料の含有量は、赤外線吸収性編織物等の面積当たり、０．０５ｇ／ｍ２以上０．５０ｇ／ｍ２以下であってよい。 The content of the infrared absorbing pigment in the infrared absorbing knitted fabric, etc. of the present invention may be 0.05 g/m 2 or more and 0.50 g/m 2 or less per area of the infrared absorbing knitted fabric, etc.
本発明所定のΔＥ要件を満たしつつ、快適な発熱性を実現するために好適な赤外線吸収性顔料の含有量は、赤外線吸収性編織物等の色調によって異なる場合がある。明るい暖色系の色調、例えば、赤系及び黄系の色調の編織物等の場合、Ｌ＊値が比較的大きく、編織物等が赤外線吸収性顔料を含むことによる色調の変化が、目視で識別し易い傾向にある。そのため、ΔＥ要件を満たすための赤外線吸収性顔料の含有量は、上限値に限界がある。この場合、赤外線吸収性顔料の面積当たりの含有量は、快適な発熱性を実現するためには、０．０１ｇ／ｍ２以上、０．０３ｇ／ｍ２以上、０．０５ｇ／ｍ２以上、０．０６ｇ／ｍ２以上、０．０８ｇ／ｍ２以上、０．１０ｇ／ｍ２以上、又は０．１２ｇ／ｍ２以上であってよく、ΔＥ要件の充足を確実化するためには、０．５０ｇ／ｍ２以下、０．４０ｇ／ｍ２以下、０．３０ｇ／ｍ２以下、０．２５ｇ／ｍ２以下、又は０．２０ｇ／ｍ２以下であってよい。 The content of the infrared absorbing pigment suitable for realizing comfortable heat generation properties while satisfying the predetermined ΔE requirements of the present invention may vary depending on the color tone of the infrared absorbing knitted fabric, etc. In the case of knitted fabrics with bright warm colors, such as red and yellow tones, the L * value is relatively large, and changes in color tone caused by the knitted fabrics containing infrared absorbing pigments can be visually discerned. It tends to be easy. Therefore, there is a limit to the upper limit of the content of the infrared absorbing pigment to satisfy the ΔE requirement. In this case, the content per area of the infrared absorbing pigment should be 0.01 g/m 2 or more, 0.03 g/m 2 or more, 0.05 g/m 2 or more, in order to achieve comfortable heat generation properties. It may be greater than or equal to 0.06 g/ m2 , greater than or equal to 0.08 g/ m2 , greater than or equal to 0.10 g/ m2 , or greater than or equal to 0.12 g/m2; It may be less than or equal to .50 g/ m2 , less than or equal to 0.40 g/ m2 , less than or equal to 0.30 g/ m2 , less than or equal to 0.25 g/ m2 , or less than or equal to 0.20 g/ m2 .
色調が特に明るく、例えば、Ｌ＊値が８０超、又は９０超の場合には、赤外線吸収性顔料の面積当たりの含有量は、色調変化の目視識別性をより困難にする観点から、０．３０ｇ／ｍ２以下、０．２５ｇ／ｍ２以下、０．２０ｇ／ｍ２以下、０．１５ｇ／ｍ２以下、０．１２ｇ／ｍ２以下、又は０．１０ｇ／ｍ２以下であってよい。 When the color tone is particularly bright, for example, when the L * value is more than 80 or more than 90, the content per area of the infrared absorbing pigment should be 0.0. May be 30 g/m 2 or less, 0.25 g/m 2 or less, 0.20 g/m 2 or less, 0.15 g/m 2 or less, 0.12 g/m 2 or less, or 0.10 g/m 2 or less .
一方、暗めの寒色系の色調、例えば、青系の色調の編織物等の場合、Ｌ＊値が比較的小さく、編織物等が赤外線吸収性顔料を含むことによる色調の変化が、目視で識別し難い傾向にある。そのため、赤外線吸収性顔料を比較的多く含んでも、ΔＥ要件を満たし易い傾向にある。この場合、快適な発熱性を実現するためには、０．０５ｇ／ｍ２以上、０．０６ｇ／ｍ２以上、０．０８ｇ／ｍ２以上、０．１０ｇ／ｍ２以上、又は０．１２ｇ／ｍ２以上であってよく、ΔＥ要件の充足を確実化するためには、０．５０ｇ／ｍ２以下、０．４８ｇ／ｍ２以下、０．４６ｇ／ｍ２以下、０．４４ｇ／ｍ２以下、０．４２ｇ／ｍ２以下、又は０．４０ｇ／ｍ２以下であってよい。 On the other hand, in the case of knitted fabrics with dark, cool tones, for example, bluish tones, the L * value is relatively small, and changes in color tone due to the knitted fabrics containing infrared absorbing pigments can be visually discerned. It tends to be difficult. Therefore, even if it contains a relatively large amount of infrared absorbing pigment, it tends to easily satisfy the ΔE requirement. In this case, in order to achieve comfortable heat generation properties, the temperature must be 0.05 g/m 2 or more, 0.06 g/m 2 or more, 0.08 g/m 2 or more, 0.10 g/m 2 or more, or 0.12 g /m 2 or more, and to ensure fulfillment of the ΔE requirements, 0.50 g/m 2 or less, 0.48 g/m 2 or less, 0.46 g/m 2 or less, 0.44 g/m 2 2 or less, 0.42 g/m 2 or less, or 0.40 g/m 2 or less.
