かかるポリエステルは任意の方法によって合成したものでよい。例えばポリエチレンテレフタレートの場合について説明すると、テレフタル酸とエチレングリコールとを直接エステル化反応させるか、テレフタル酸ジメチルのごときテレフタル酸の低級アルキルエステルとエチレングリコールとをエステル交換反応させるかまたはテレフタル酸とエチレンオキサイドとを反応させるかしてテレフタル酸のグリコールエステルおよび／またはその低重合体を生成させる第１段階の反応と、第１段階の反応生成物を減圧下加熱して所望の重合度になるまで重縮合反応させる第２段階の反応によって製造されたものでよい。 Such polyester may be synthesized by any method. For example, in the case of polyethylene terephthalate, terephthalic acid and ethylene glycol are directly esterified, or a lower alkyl ester of terephthalic acid such as dimethyl terephthalate is transesterified with ethylene glycol, or terephthalic acid and ethylene oxide are used. And the first stage reaction to produce a terephthalic acid glycol ester and / or its low polymer, and the first stage reaction product is heated under reduced pressure until the desired degree of polymerization is reached. It may be produced by a second stage reaction for condensation reaction.
かかるポリエステル繊維において、ポリエステル中に有機系紫外線吸収剤がポリエステル重量に対し０．１〜５．０重量％（好ましくは０．５〜３．０重量％）含まれることが肝要である。有機系紫外線吸収剤の含有量が０．１重量％よりも小さいと、十分な紫外線吸収性能が得られず好ましくない。逆に、有機系紫外線吸収剤の含有量が５．０重量％よりも大きいと、有機系紫外線吸収剤を含むポリエステルを紡糸してポリエステル繊維を得る際、紡糸の工程安定性が損なわれたり、時間の経過とともにポリエステル繊維が黄変するおそれがあるので好ましくない。 In such a polyester fiber, it is important that the organic ultraviolet absorber is contained in the polyester in an amount of 0.1 to 5.0% by weight (preferably 0.5 to 3.0% by weight) based on the weight of the polyester. When the content of the organic ultraviolet absorber is less than 0.1% by weight, sufficient ultraviolet absorption performance cannot be obtained, which is not preferable. Conversely, when the content of the organic ultraviolet absorber is greater than 5.0% by weight, the spinning process stability is impaired when spinning polyester containing the organic ultraviolet absorber to obtain a polyester fiber. This is not preferable because the polyester fiber may be yellowed over time.
ポリエステル中に含まれる有機系紫外線吸収剤としては、ベンゾオキサジン系有機紫外線吸収剤、ベンゾフェノン系有機紫外線吸収剤、ベンゾトリアゾール系有機紫外線吸収剤、サリチル酸系有機紫外線吸収剤などが例示される。なかでも、紡糸の段階で分解しないという点からベンゾオキサジン系有機紫外線吸収剤が特に好ましい。 Examples of organic ultraviolet absorbers contained in the polyester include benzoxazine organic ultraviolet absorbers, benzophenone organic ultraviolet absorbers, benzotriazole organic ultraviolet absorbers, and salicylic acid organic ultraviolet absorbers. Of these, benzoxazine-based organic ultraviolet absorbers are particularly preferred because they do not decompose at the spinning stage.
かかるベンゾオキサジン系有機紫外線吸収剤としては、特開昭６２−１１７４４号公報に開示されたものが好適に例示される。すなわち、２−メチル−３，１−ベンゾオキサジン−４−オン、２−ブチル−３，１−ベンゾオキサジン−４−オン、２−フェニル−３，１−ベンゾオキサジン−４−オン、２，２’−エチレンビス（３，１−ベンゾオキサジン−４−オン）、２，２’−テトラメチレンビス（３，１−ベンゾオキサジン−４−オン）、２，２’−ｐ−フェニレンビス（３，１−ベンゾオキサジン−４−オン）、１，３，５−トリ（３，１−ベンゾオキサジン−４−オン−２−イル）ベンゼン、１，３，５−トリ（３，１−ベンゾオキサジン−４−オン−２−イル）ナフタレンなどである。 Suitable examples of such benzoxazine-based organic ultraviolet absorbers are those disclosed in JP-A-62-1744. That is, 2-methyl-3,1-benzoxazin-4-one, 2-butyl-3,1-benzoxazin-4-one, 2-phenyl-3,1-benzoxazin-4-one, 2,2 '-Ethylenebis (3,1-benzoxazin-4-one), 2,2'-tetramethylenebis (3,1-benzoxazin-4-one), 2,2'-p-phenylenebis (3 1-benzoxazin-4-one), 1,3,5-tri (3,1-benzoxazin-4-one-2-yl) benzene, 1,3,5-tri (3,1-benzoxazine- 4-on-2-yl) naphthalene and the like.
また、前記のポリエステル繊維を形成するポリエステル中に、無機系の紫外線吸収および／または反射剤を０．５重量％以下含有することが肝要である。かかる紫外線吸収および／または反射剤は少ないほどよく、ポリエステル繊維中に含有していないことがもっとも好ましい。無機系の紫外線吸収および／または反射剤の含有量が０．５重量％よりも大きいと、可視光線を反射してしまい、採光性が損なわれるので好ましくない。なお、前記の無機系の紫外線吸収および／または反射剤としては、二酸化チタン、酸化亜鉛、アルミナ、酸化マグネシウム、タルク、カリオン、炭酸カルシウム、炭酸ナトリウム等の無機化合物があげられる。 In addition, it is essential that the polyester forming the polyester fiber contains an inorganic ultraviolet absorbing and / or reflecting agent in an amount of 0.5% by weight or less. The smaller the ultraviolet absorption and / or reflection agent is, the better, and most preferably it is not contained in the polyester fiber. When the content of the inorganic ultraviolet ray absorption and / or the reflective agent is larger than 0.5% by weight, visible light is reflected and the daylighting property is impaired. Examples of the inorganic ultraviolet absorbing and / or reflecting agent include inorganic compounds such as titanium dioxide, zinc oxide, alumina, magnesium oxide, talc, carion, calcium carbonate, and sodium carbonate.
本発明において、ポリエステル繊維は、有機系紫外線吸収剤を０．１〜５．０重量％含有し、無機系の紫外線吸収および／または反射剤を０．５重量％以下含有する、固有粘度が０．５５〜０．８０の前記ポリエステルを、常法により紡糸し、２０００〜４３００ｍ／分の速度で未延伸糸（中間配向糸）として一旦巻き取り、延伸したものでもよいし、巻き取る前に延伸したものでもよい。また、中間配向糸を、１８０〜２００℃に加熱されたヒーターを用いて、弛緩状態（オーバーフィード１．５〜１０％）で熱処理することにより、加熱下で自己伸長性を有する未延伸糸（中間配向糸）であってもよい。 In the present invention, the polyester fiber contains 0.1 to 5.0% by weight of an organic UV absorber and 0.5% by weight or less of an inorganic UV absorber and / or reflector, and has an intrinsic viscosity of 0. The polyester of .55 to 0.80 is spun by a conventional method, wound once as an undrawn yarn (intermediate oriented yarn) at a speed of 2000 to 4300 m / min, and may be drawn or drawn before winding. You may have done. In addition, the intermediate oriented yarn is heat-treated in a relaxed state (overfeed 1.5 to 10%) using a heater heated to 180 to 200 ° C., so that an undrawn yarn having self-extensibility under heating ( Intermediately oriented yarn).
かかるポリエステル繊維において、単繊維繊度が０．１〜５．０ｄｔｅｘの範囲内であることが好ましい。また、繊維の形態としては、短繊維でもよいし長繊維（マルチフィラメント）でもよい。なかでも、織編物とした場合の組織間空隙を小さくして紫外線の透過量を少なくする上で長繊維が好ましい。 In such a polyester fiber, the single fiber fineness is preferably in the range of 0.1 to 5.0 dtex. Moreover, as a form of a fiber, a short fiber may be sufficient and a long fiber (multifilament) may be sufficient. Among these, long fibers are preferable in order to reduce the amount of transmitted ultraviolet light by reducing the inter-structure voids in the case of a woven or knitted fabric.
なお、かかる長繊維の総繊度、フィラメント数としては、総繊度３３〜３３０ｄｔｅｘ、フィラメント数１０〜１００の範囲が好ましい。また、単繊維の断面形状は特に限定されず通常の丸断面でもよいし、扁平断面、くびれつき扁平断面、三角断面、四角断面、３〜１４葉断面、中空断面などの異型断面でもよい。特に、織編物とした場合の組織間空隙を小さくする上で異型断面が好ましい。特に、図１に模式的に示すような、２箇所以上のくびれ部を有する断面扁平度２〜６の扁平断面を採用すると、織編物とした場合の組織間空隙を小さくすることができ、かつソフトな風合いが得られ好ましい。なお、断面扁平度とは、図１に示す、長辺の長さ（Ｂ）と短辺の長さ（Ｃ１）との比（Ｂ／Ｃ１）である。また、くびれ部とは図１に模式的に示すように、短辺の長さが短くなっている部分のことである。かかるくびれ部において、凹部の深さとしては、短辺の長さの最大値と最小値の比（Ｃ１／Ｃ２）で、１．０５以上（好ましくは１．１以上）となる深さであることが好ましい。なお、図１は、くびれ部が３個所の場合を例示するものである。 The total fineness and the number of filaments of such long fibers are preferably in the range of a total fineness of 33 to 330 dtex and a number of filaments of 10 to 100. In addition, the cross-sectional shape of the single fiber is not particularly limited, and may be a normal round cross section, or a flat cross section, a constricted flat cross section, a triangular cross section, a square cross section, a 3-14 leaf cross section, a hollow cross section, and the like. In particular, the modified cross section is preferable in order to reduce the inter-structure voids in the case of a woven or knitted fabric. In particular, when a flat cross section having a cross-sectional flatness of 2 to 6 having two or more constricted portions as schematically shown in FIG. 1 is adopted, the inter-tissue gap in the case of a woven or knitted fabric can be reduced, and A soft texture is obtained, which is preferable. The cross-sectional flatness is the ratio (B / C1) between the length (B) of the long side and the length (C1) of the short side shown in FIG. Further, the constricted portion is a portion where the length of the short side is shortened as schematically shown in FIG. In such a constricted portion, the depth of the concave portion is a depth that is 1.05 or more (preferably 1.1 or more) as a ratio (C1 / C2) of the maximum value and the minimum value of the length of the short side. It is preferable. FIG. 1 illustrates the case where there are three constricted portions.
また、かかるポリエステル繊維は無撚であると、布帛の空隙を小さくすることができ、紫外線カット性が向上し好ましい。撚りを施す場合は、下記の撚り係数が６０００以下であることが好ましい。撚り係数が６０００よりも大きいと、布帛の空隙が大きくなり紫外線カット性が低下するおそれがある。また同時に、繊維がコイル状となるため可視光線の乱反射を生じ、採光性が損なわれるおそれがある。 In addition, it is preferable that the polyester fiber is non-twisted because the gap of the fabric can be reduced, and the ultraviolet ray cutting property is improved. When twisting, it is preferable that the following twist coefficient is 6000 or less. When the twisting coefficient is larger than 6000, the gap of the fabric becomes large, and there is a possibility that the ultraviolet ray cutting property is lowered. At the same time, since the fiber is coiled, visible light is irregularly reflected, and there is a possibility that the daylighting property is impaired.
本発明の布帛は、前記のポリエステル繊維を布帛重量に対し３０重量％以上（より好ましくは６０重量％以上、特に好ましくは１００重量％）含む布帛である。前記のポリエステル繊維の含有量が３０重量％よりも小さいと、十分な紫外線カット性が得られず好ましくない。 The fabric of the present invention is a fabric containing 30% by weight or more (more preferably 60% by weight or more, particularly preferably 100% by weight) of the polyester fiber described above with respect to the weight of the fabric. When the content of the polyester fiber is less than 30% by weight, it is not preferable because sufficient UV cut-off property cannot be obtained.
布帛の織編組織は特に限定されず、通常の方法で製編織されたものでよい。さらには、不織布であってもよい。例えば、織物の織組織としては、平織、綾織、朱子織等の三原組織、変化組織、たて二重織、よこ二重織等の片二重組織、たてビロードなどが例示される。編物の種類は、よこ編物であってもよいしたて編物であってもよい。よこ編組織としては、平編、ゴム編、両面編、パール編、タック編、浮き編、片畔編、レース編、添え毛編等が好ましく例示され、たて編組織としては、シングルデンビー編、シングルアトラス編、ダブルコード編、ハーフトリコット編、裏毛編、ジャガード編等が例示される。層数も単層でもよいし、２層以上の多層でもよい。 The woven or knitted structure of the fabric is not particularly limited, and may be knitted and woven by a normal method. Furthermore, a nonwoven fabric may be sufficient. For example, examples of the woven structure of the woven fabric include a three-layer structure such as plain weave, twill weave and satin weave, a change structure, a single double structure such as a vertical double weave and a horizontal double weave, and a vertical velvet. The type of knitted fabric may be a weft knitted fabric or a newly knitted fabric. Preferred examples of the weft knitting structure include flat knitting, rubber knitting, double-sided knitting, pearl knitting, tuck knitting, float knitting, one-sided knitting, lace knitting, bristle knitting, and the like. Single atlas knitting, double cord knitting, half tricot knitting, back hair knitting, jacquard knitting and the like are exemplified. The number of layers may be a single layer or a multilayer of two or more layers.
ここで、本発明の布帛が織物である場合は、下記式により算出されるカバーファクター（ＣＦ）が１５００〜３０００であることが好ましい。該カバーファクターが１５００よりも小さいと、織物の組織間空隙が大きくなり、紫外線カット性が損なわれるおそれがある。紫外線カット性の点では、該カバーファクターは大きいほどよいが、３０００よりも大きいと布帛のソフト性が損なわれるおそれがある。
ＣＦ＝（ＤＷｐ／１．１）１／２×ＭＷｐ＋（ＤＷｆ／１．１）１／２×ＭＷｆ
ただし、ＤＷｐは経糸総繊度（ｄｔｅｘ）、ＭＷｐは経糸織密度（本／２．５４ｃｍ）、ＤＷｆは緯糸総繊度（ｄｔｅｘ）、ＭＷｆは緯糸織密度（本／２．５４ｃｍ）である。
Here, when the fabric of the present invention is a woven fabric, the cover factor (CF) calculated by the following formula is preferably 1500 to 3000. If the cover factor is less than 1500, the inter-texture voids of the woven fabric become large, and the UV cut ability may be impaired. The larger the cover factor is, the better in terms of UV-cutting properties. However, if it is larger than 3000, the softness of the fabric may be impaired.
CF = (DWp / 1.1) 1/2 × MWp + (DWf / 1.1) 1/2 × MWf
However, DWp is the total warp fineness (dtex), MWp is the warp weave density (main / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (main / 2.54 cm).

Various processings that provide functions such as a retroreflective agent and a negative ion generator may be additionally applied.
本発明の布帛において、紫外線は前記のポリエステル繊維により吸収されるので、紫外線がカットされる。かかる紫外線カット性としては、波長２８０〜４００ｎｍの紫外線の透過率が１５％以下（より好ましくは１〜１０％）であることが好ましい。なお、かかる紫外線カット性は、布帛に含まれる前記ポリエステル繊維の含有量や、織編の組織密度を適宜選定することにより容易に得られる。 In the fabric of the present invention, ultraviolet rays are absorbed by the polyester fiber, so that the ultraviolet rays are cut. As such ultraviolet-cutting property, it is preferable that the transmittance | permeability of the ultraviolet-ray with a wavelength of 280-400 nm is 15% or less (more preferably 1-10%). Such UV-cutting property can be easily obtained by appropriately selecting the content of the polyester fiber contained in the fabric and the texture density of the woven or knitted fabric.
また、本発明の布帛において、可視光線は前記のポリエステル繊維によりあまり反射されずに透過するので、優れた採光性が得られる。かかる採光性としては、波長４００〜７００ｎｍの可視光線の反射率が５５％以下（より好ましくは２０〜５０％）であることが好ましい。 Further, in the fabric of the present invention, visible light is transmitted without being reflected by the polyester fiber so that an excellent daylighting property is obtained. As such daylighting property, the reflectance of visible light having a wavelength of 400 to 700 nm is preferably 55% or less (more preferably 20 to 50%).
本発明の布帛は、優れた紫外線カット性と採光性とを有しているので、カーテン、テント、寝具、障子紙、衣服、帽子などの繊維製品として好適に使用することができる。 Since the fabric of the present invention has excellent ultraviolet cutting properties and daylighting properties, it can be suitably used as textile products such as curtains, tents, bedding, shoji paper, clothes, and hats.
