Description
本発明は、紫外線吸収性能を有する網戸用ネットに関するものである。 The present invention relates to a net for screen doors having ultraviolet absorption performance.
従来、網戸は家屋をはじめとする建造物において広く用いられている。網戸は、建造物の窓部等に取り付けられ、窓を開けて内外気の交換を行なう際、虫や塵の室内侵入を防ぐ役割を果たす物である。これまで用いられてきた網戸用ネットとしては、ポリエステル、ポリプロピレン、ポリエチレン、ポリ塩化ビニル等の熱可塑性樹脂、或いはステンレスやアルミといった金属が用いられ、繊径が２００〜３００μｍ程度の比較的太いモノフィラメントを経糸及び緯糸に配し、織密度１４〜２２本／ｉｎｃｈという比較的低い密度で織られたものがよく知られている（例えば、特許文献１、特許文献２参照）。しかし、このような太径のモノフィラメントを用いて低密度で織られた網戸用ネットは、通気性は高いものの、紫外線の透過を抑制することができなかった。 Conventionally, screen doors are widely used in buildings and other buildings. The screen door is attached to a window portion of a building and plays a role of preventing insects and dust from entering the room when opening the window and exchanging the inside and outside air. As nets for screen doors that have been used so far, thermoplastic resins such as polyester, polypropylene, polyethylene, polyvinyl chloride, or metals such as stainless steel and aluminum are used, and relatively thick monofilaments having a fine diameter of about 200 to 300 μm are used. It is well known that it is arranged on warps and wefts and is woven at a relatively low density of 14-22 yarns / inch (for example, see Patent Document 1 and Patent Document 2). However, nets for screen doors woven at a low density using such thick monofilaments have high air permeability but cannot suppress ultraviolet light transmission.
これに対して、紫外線の透過を抑制する網戸として、紫外線をカットするフィルムを貼着した網戸が提案されている（特許文献３参照）。しかしながら、かかる網戸には、フィルムによってメッシュの開口部が塞がれ通気性が低下するという問題があり、網戸本来の機能を有するものではない。 On the other hand, the screen door which stuck the film which cuts off an ultraviolet-ray is proposed as a screen door which suppresses permeation | transmission of an ultraviolet-ray (refer patent document 3). However, the screen door has a problem that the opening of the mesh is blocked by the film and the air permeability is lowered, and does not have the original function of the screen door.
一方、粉塵や花粉等の侵入を防ぎ、これらの微細な有害物質を効果的に捕捉できる網戸用ネットとして、細いモノフィラメントからなる高密度の網戸用ネットが提案されている（特許文献４参照）。しかし、かかる高密度な網戸用ネットは、微細な有害物質を捕捉する効果はあるものの、紫外線の透過までを抑制することはできないものである。 On the other hand, a high-density screen door net composed of thin monofilaments has been proposed as a screen door net that can prevent the entry of dust, pollen, and the like and effectively capture these fine harmful substances (see Patent Document 4). However, such a high-density screen door net has an effect of capturing fine harmful substances, but cannot suppress the transmission of ultraviolet rays.
本発明は、かかる従来技術が有する問題点を解決する為になされたものであり、その目的は、紫外線透過抑制機能を有する網戸用ネットを提供することにある。 The present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide a screen door net having a function of suppressing transmission of ultraviolet rays.
本発明者らが鋭意検討した結果、上記目的は、細い繊径のモノフィラメントからなる織密度の高いメッシュ織物を用い、それに付与する紫外線吸収剤について検討した結果、該剤によっては、モノフィラメントの物性の低下を抑制するだけでなく、屋内への紫外線の侵入を著しく防止できることを見出した。 As a result of intensive studies by the present inventors, the above object is to use a mesh fabric having a high woven density made of monofilaments having a small diameter, and as a result of investigating an ultraviolet absorber to be applied thereto, depending on the agent, the physical properties of the monofilament It has been found that not only the decrease can be suppressed, but also the invasion of ultraviolet rays into the indoor can be remarkably prevented.
かくして、本発明によれば、繊維形成性熱可塑性ポリマーからなるモノフィラメントが経糸及び緯糸に配されてなる織物からなる網戸用ネットであって、該モノフィラメントの直径が１０〜１００μｍ、該織物の経方向、緯方向の織密度が共に５０〜５００本／ｉｎｃｈであり、かつ該織物に、粒径が０．０１〜０．５μｍの紫外線吸収剤が該織物の重量に対して１．０〜１０．０重量％付着していることを特徴とする網戸用ネットが提供される。また、該織物を黄色染料で、染色することによって、両方の効果が相まって、一段と紫外線抑制効果が高くなることを見出した。 Thus, according to the present invention, there is a net for net doors made of a woven fabric in which monofilaments made of a fiber-forming thermoplastic polymer are arranged on warps and wefts, and the diameter of the monofilament is 10 to 100 μm, the warp direction of the woven fabric The weft density in the weft direction is 50 to 500 / inch, and the UV absorbent having a particle size of 0.01 to 0.5 μm is 1.0 to 10. There is provided a net for net doors characterized by adhering 0% by weight. Further, it has been found that dyeing the woven fabric with a yellow dye increases the effect of suppressing ultraviolet rays by combining both effects.
本発明によれば、通気性を低下させる事無く、優れた紫外線透過抑制機能を有する網戸用ネットが提供される。 ADVANTAGE OF THE INVENTION According to this invention, the net | network for screen doors which has the outstanding ultraviolet-ray transmission suppression function is provided, without reducing air permeability.
本発明の網戸用ネットは、繊維形成性熱可塑性ポリマーからなるモノフィラメントが経糸及び緯糸に配されてなる織物からなる網戸用ネットであって、該モノフィラメントの直径が１０〜１００μｍ、該織物の経方向、緯方向の織密度が共に５０〜５００本／ｉｎｃｈであり、かつ該織物に、粒径が０．０１〜０．５μｍの紫外線吸収剤が該織物の重量に対して１．０〜５．０重量％付着していることを特徴とする網戸用ネットであり、以下、詳細に説明する。 The screen door net of the present invention is a screen door net made of a woven fabric in which monofilaments made of a fiber-forming thermoplastic polymer are arranged on warps and wefts, and the diameter of the monofilament is 10 to 100 μm, the warp direction of the woven fabric The weave density in the weft direction is 50 to 500 yarns / inch, and an ultraviolet absorber having a particle size of 0.01 to 0.5 μm is added to the woven fabric in an amount of 1.0 to 5. This is a net for net doors characterized by adhering to 0% by weight, and will be described in detail below.
まず、本発明の網戸用ネットを構成する、繊維形成性熱可塑性ポリマーからなるモノフィラメントの直径は１０〜１００μｍ、好ましくは２０〜８０μｍである。該直径が１００μｍよりも大きくなると、高い密度で織る事が難しくなる上、通気性も低下する為好ましくない。また逆に、該直径が１０μｍより小さくなると、強度が低下し、製織中或いは使用中にモノフィラメントが切れてしまう恐れがある為好ましくない。係るモノフィラメントの繊径については、経糸と緯糸で同じであっても良いし、異なっていても良い。 First, the diameter of the monofilament which consists of a fiber-forming thermoplastic polymer which comprises the net | network for screen doors of this invention is 10-100 micrometers, Preferably it is 20-80 micrometers. When the diameter is larger than 100 μm, it is difficult to weave at a high density and air permeability is also lowered, which is not preferable. On the other hand, if the diameter is smaller than 10 μm, the strength is lowered, and the monofilament may be broken during weaving or use. The fine diameter of the monofilament may be the same or different between the warp and the weft.
前記モノフィラメントを形成する繊維形成性熱可塑性ポリマーの具体例としては、ポリエステル、ポリプロピレン、ポリエチレン、ポリ塩化ビニル等が挙げられ、中でも、ポリエステルが最も好ましい。繊維形成性熱可塑性ポリマーとしてポリエステルを採用する事で織物の染色が可能となり、プリント柄の使用、或いは、着色により更なる紫外線透過抑制機能の付与が可能となる。 Specific examples of the fiber-forming thermoplastic polymer that forms the monofilament include polyester, polypropylene, polyethylene, polyvinyl chloride, and the like. Among these, polyester is most preferable. By using polyester as the fiber-forming thermoplastic polymer, it is possible to dye the fabric, and use of a printed pattern or coloring can further impart an ultraviolet transmission suppression function.
上記のポリエステルとしては、主たる繰り返し単位がエチレンテレフタレートであるポリエチレンテレフタレート系ポリエステル、又は、主たる繰り返し単位がブチレンテレフタレートであるポリブチレンテレフタレート系ポリエステル、又は、主たる繰り返し単位がトリメチレンテレフタレートであるポリトリメチレンテレフタレート系ポリエステルが好ましい。 As the above polyester, a polyethylene terephthalate-based polyester whose main repeating unit is ethylene terephthalate, a polybutylene terephthalate-based polyester whose main repeating unit is butylene terephthalate, or a polytrimethylene terephthalate whose main repeating unit is trimethylene terephthalate Polyesters are preferred.
前記の繊維形成性熱可塑性ポリマーには、本発明の目的を損なわない範囲で必要に応じて添加剤を加えても良い。添加剤としては、細細孔形成剤、カチオン可染剤、着色剤、着色防止剤、熱安定剤、難燃剤、蛍光増白剤、艶消し剤、帯電防止剤、吸湿剤、抗菌剤、無機微粒子等が挙げられる。 If necessary, an additive may be added to the fiber-forming thermoplastic polymer as long as the object of the present invention is not impaired. Additives include fine pore forming agents, cationic dyes, colorants, anti-coloring agents, heat stabilizers, flame retardants, fluorescent brighteners, matting agents, antistatic agents, hygroscopic agents, antibacterial agents, inorganic Examples thereof include fine particles.
前記モノフィラメントの繊維形態は、繊維軸方向に連続したモノフィラメントであれば特に限定されず、その断面形状も特に限定されない。断面形状としては、丸、三角、扁平、中空等が挙げられる。尚、モノフィラメントの断面形状が丸以外の場合、繊径は径の最大部を測定するものとする。更に、該モノフィラメントは、常法の紡糸方法により得られるもので良く、強伸度の物性については特に限定されない。 The fiber form of the monofilament is not particularly limited as long as it is a monofilament continuous in the fiber axis direction, and the cross-sectional shape is not particularly limited. Examples of the cross-sectional shape include a circle, a triangle, a flat shape, and a hollow shape. When the cross-sectional shape of the monofilament is other than round, the fine diameter is measured at the maximum portion of the diameter. Furthermore, the monofilament may be obtained by a conventional spinning method, and the physical properties of the high elongation are not particularly limited.
本発明の網戸用ネットを構成する織物は、前記のモノフィラメントが、経糸及び緯糸に配された織物である。織密度としては、経方向、緯方向共に５０〜５００本／ｉｎｃｈ、好ましくは８０〜４００本／ｉｎｃｈである。織密度が５００本／ｉｎｃｈよりも大きいと、製織が困難となる上、開口部が小さくなり過ぎて通気性が低下する為好ましくない。また逆に、織密度が５０本／ｉｎｃｈよりも小さいと、開口部が大きくなり過ぎて網戸用ネットとしての濾過機能、及び紫外線透過抑制機能が低下する為好ましくない。かかる織物の織密度については、経方向と緯方向で同じであっても良いし、異なっていても良い。かかる織物の織組織については特に限定されない。織組織としては平織、綾織、朱子織等が挙げられるが、中でも、強度を保持し目ズレを低減させる上で平組織が最も好ましい。また、かかる織物は、レピア織機等の織機を用いて常法の製織により得られる。 The woven fabric constituting the screen door net of the present invention is a woven fabric in which the monofilament is arranged on warps and wefts. The weaving density is 50 to 500 / inch, preferably 80 to 400 / inch in both the warp and weft directions. If the weaving density is higher than 500 / inch, weaving becomes difficult, and the opening becomes too small, resulting in a decrease in air permeability. On the contrary, if the weave density is less than 50 / inch, the opening becomes too large, and the filtering function as the net for screen doors and the ultraviolet ray transmission suppressing function are not preferable. The woven density of the woven fabric may be the same in the warp direction and the weft direction, or may be different. The woven structure of the woven fabric is not particularly limited. Examples of the weave structure include plain weave, twill weave, and satin weave. Among these, the plain structure is most preferable in order to maintain strength and reduce misalignment. Such a woven fabric can be obtained by ordinary weaving using a loom such as a rapier loom.
本発明の網戸用ネットにおいては、粒径が０．０１〜０．５μｍ、好ましくは０．０５〜０．４μｍ、より好ましくは０．０５〜０．３μｍの紫外線吸収剤が該織物の重量に対して１．０〜５．０重量％付着していることが肝要である。かかる紫外線吸収剤としては、ベンゾトリアゾール系、ベンゾフェノン系、トリアジン系、サリチル酸系等が挙げられるが、中でも、ベンゾトリアゾール系が好ましい。例えば、通常用いられるベンゾトリアゾール系紫外線吸収剤の粒径は０．７μｍ程度であるが、本発明においては上記粒径に微粒子化された紫外線吸収剤を織物に付着させることで、均一かつ効率的に紫外線吸収性能を付与することができることを見出した。 In the screen door net of the present invention, an ultraviolet absorber having a particle size of 0.01 to 0.5 μm, preferably 0.05 to 0.4 μm, more preferably 0.05 to 0.3 μm is added to the weight of the fabric. On the other hand, it is important that 1.0 to 5.0% by weight is adhered. Examples of the ultraviolet absorber include benzotriazole, benzophenone, triazine, salicylic acid, and the like, among which benzotriazole is preferable. For example, the particle size of a commonly used benzotriazole ultraviolet absorber is about 0.7 μm. In the present invention, the ultraviolet absorber finely divided to the above particle size is attached to a fabric, thereby making it uniform and efficient. It has been found that UV absorption performance can be imparted to.
かかる紫外線吸収剤の付着量としては、織物の重量に対して１．０〜５．０重量％、好ましくは１．０〜３．０重量％である。紫外線吸収剤の添加量が１．０重量％より少ないと、十分な紫外線透過抑制機能を得ることができず、また逆に５．０重量％より多いと、添加した剤の量に比例した紫外線透過抑制機能を得ることができない。 The adhesion amount of the ultraviolet absorber is 1.0 to 5.0% by weight, preferably 1.0 to 3.0% by weight, based on the weight of the fabric. If the added amount of the UV absorber is less than 1.0% by weight, a sufficient UV light transmission inhibiting function cannot be obtained. A permeation suppression function cannot be obtained.
本発明の網戸用ネットは、無着色でも良いが、黄色に着色するのが好ましい。黄色に着色することにより、紫外線吸収性能を一層高めることが可能となる。本発明に用いる染料は、アゾ系、アントラキノン系の黄色分散染料を挙げることができ、中でも特にアゾ系染料が望ましい。かかるアゾ系染料としては具体的には、Dianix Yellow AC-E、Dianix Yellow S-6G、Dianix Orange Plus、 Mikeron Polyester Yellow 5G、MikeronPolyester Yellow 5G（以上、ダイスタージャパン株式会社）、CIBASET Yellow 2GC、TERASIL Yellow 4G（以上、チバ・スペシャルティ・ケミカルズ株式会社）、Kayalon Polyester Yellow 4G-E（日本化薬株式会社）を挙げることができる。 The screen door net of the present invention may be uncolored, but is preferably colored yellow. By coloring yellow, the ultraviolet absorption performance can be further enhanced. Examples of the dye used in the present invention include azo and anthraquinone yellow disperse dyes, and azo dyes are particularly preferable. Specific examples of such azo dyes include Dianix Yellow AC-E, Dianix Yellow S-6G, Dianix Orange Plus, Mikeron Polyester Yellow 5G, Mikeron Polyester Yellow 5G (above, Dystar Japan Co., Ltd.), CIBASET Yellow 2GC, TERASIL Examples include Yellow 4G (above, Ciba Specialty Chemicals Co., Ltd.) and Kaylon Polyester Yellow 4G-E (Nippon Kayaku Co., Ltd.).
かかる染料の含有量としては、織物の重量に対して好ましくは１．０〜５．０重量％、より好ましくは１．０〜３．０重量％である。染料の含有量が１．０重量％より少ないと、十分な紫外線透過抑制機能が低下する傾向にあり、また逆に５．０重量％より多いと、それ以上量を多くしても紫外線透過抑制機能が得られず、染色堅牢性が低下し、洗濯等で他の衣料を汚染し易くなり好ましくない。 The content of the dye is preferably 1.0 to 5.0% by weight, more preferably 1.0 to 3.0% by weight, based on the weight of the fabric. If the content of the dye is less than 1.0% by weight, the sufficient UV transmission inhibiting function tends to be lowered. Conversely, if it exceeds 5.0% by weight, the UV transmission is suppressed even if the amount is increased further. The function cannot be obtained, the dyeing fastness is lowered, and other clothes are easily contaminated by washing or the like, which is not preferable.
本発明おいては、屋内への紫外線の侵入を防止する上で、網戸用ネットの、波長２８０〜３８０ｎｍにピークを有する紫外線に対する透過率が５０％未満であることが望ましく、前記の量および粒径の紫外線吸収剤を織物に付着させることにより、これを達成することができる。また、該織物を黄色染料で、染色することによって、両方の効果が相まって、一段と紫外線抑制効果が高くなり、上記透過率を容易に達成することができる。 In the present invention, in order to prevent ultraviolet rays from entering indoors, the screen door net preferably has a transmittance of ultraviolet light having a peak at a wavelength of 280 to 380 nm of less than 50%. This can be achieved by attaching a UV absorber of diameter to the fabric. Further, by dyeing the woven fabric with a yellow dye, both effects are combined, and the ultraviolet light suppressing effect is further enhanced, and the above transmittance can be easily achieved.
本発明において、織物に紫外線抑制剤を付着させる方法としては、染色前加工時に付加する方法、染色浴中に添加する方法、染色後加工時に付加する方法等が挙げられるが、染色浴中に添加する方法が最も好ましい。 In the present invention, as a method of attaching the UV inhibitor to the fabric, there are a method of adding it during the pre-dyeing process, a method of adding it to the dyeing bath, a method of adding it after the dyeing process, etc. The method is most preferable.
染色方法としては、ビーム染色、ジッガー染色、チーズ染色、液流染色等が挙げられるが、目ズレやシワが起こり難いビーム染色が最も好ましい。また、染色加工条件としては、温度１３０〜１３５℃、３０〜６０分間の範囲が好ましい。 Examples of the dyeing method include beam dyeing, jigger dyeing, cheese dyeing, liquid dyeing, and the like, but beam dyeing that hardly causes misalignment and wrinkles is most preferable. Moreover, as dyeing | staining process conditions, the temperature of 130-135 degreeC and the range for 30 to 60 minutes are preferable.
