及びその製造方法 技術分野 本発明は、 染料移行による汚染のないポリエステル繊 維コーティ ング加工布及びその製造方法に関するもので ある。 背景技術 現在、 コーティ ング加工布と しては、 ナイ ロ ン繊維を 主体と した織編物に、 例えば、 撥水 · 防水、 透湿 · 撥水 通気性、 防炎防融コーティ ング等の加工を施したものが 衣料用または産業用に幅広く利用されている。  TECHNICAL FIELD The present invention relates to a polyester fiber coated cloth free from contamination due to dye transfer and a method for producing the same. BACKGROUND ART At present, as a coated fabric, a woven or knitted fabric mainly composed of nylon fiber is subjected to processing such as water-repellent / waterproof, moisture-permeable / water-repellent, air-permeable, and flame-proof / melt-proof coating. The applied materials are widely used for clothing or industrial use.
しかしながら、 近年ナイ ロ ン繊維とポリエステル繊維 との価格差が一段と拡大してきたので、 ポ リ エステル繊 維のコ一ティ ング加工の開発が盛んに行なわれるよ うに なってきた。 ポ リ エステル繊維には、 寸法安定性、 強度- 耐光性、 また素材の多様性等ナイロン繊維より も優れた 点 あ <S> o  However, in recent years, the price difference between nylon fiber and polyester fiber has further expanded, and the development of coating processing for polyester fiber has been actively pursued. Polyester fiber is superior to nylon fiber in terms of dimensional stability, strength-light resistance, and variety of materials <S> o
しかし、 ポリエステル繊維コーティ ング加工布では、 染料のコ一ティ ング膜への移行が著しく、 基布面が染色 された製品のコーティ ング膜自身及び、 それと膜面同士 で接触する他のコーティ ング膜が汚染するという致命的 な問題が有った。 すなわち、 分散染料染めの場合は、 例 えばナイロンの酸性染料染めのように繊維と染料が化学 的に結合されたものでない上、 分散染料が有機溶剤や合 成樹脂に対して溶解性、 親和性を有する特性上、 コーテ ィ ング被膜層に移行しやすいからと考えられる。 However, in the case of polyester fiber-coated cloth, the dye is remarkably transferred to the coating film, and the base fabric surface is dyed. There was a fatal problem that the coated film itself of the product and the other coated film that came into contact with the film surface were contaminated. That is, in the case of disperse dyeing, the fiber and the dye are not chemically bonded, as in the case of acid dyeing of nylon, for example, and the disperse dye is soluble and compatible with organic solvents and synthetic resins. This is considered to be due to the fact that the film easily migrates to the coating film layer due to the properties having the above.
従って、 異色のコーティ ング面が接触すると染料が移 行し、 汚染を生ずることになる。 かかる問題に関しては 現在までに種々検討が行なわれてきたが完全なものはな く、 ポリエステル系コーティ ング加工布の染色品は汎用 されていないのが現状である。  Therefore, contact between different colored coating surfaces will result in migration of the dye and contamination. Various studies have been conducted to date on such problems, but none have been completed, and at present the dyed products of polyester-coated fabrics are not widely used.
従来、 特開昭 5 8 - 4 8 7 3号公報および特公昭 6 2 - 5 3 6 3 2号公報には、 S i 0 2 を主成分とする多孔 性粒子を含むポリ ウレタ ン樹脂皮膜を形成せしめた繊維 構造物に、 パーフルォ口アルキル基を有する撥水剤を付 与する繊維構造物の加工方法が提案されている。 しかし これら両発明の目的とするところは、 ポリ ウレタ ン樹脂 中の粒子の微細孔を空気、 蒸気の流路とすることによつ て、 通気性、 透湿性を持った防水布帛を得よう とするも のであって、 現実に分散染料による汚染を防止し得るコ 一ティ ング膜に関しては示唆されていない。 発明の開示 本発明は、 分散染料を特定孔径の微細孔を有する多孔 性無機微粒子で捕捉し、 布帛面から他の布帛面への染料 の移動 · 汚染が少ないポリエステル繊維コーティ ング加 ェ布及びその製造方法を提供するものである。 Conventionally, JP-5 8 - 4 8 7 3 JP and Sho 6 2 - 5 3 6 3 2 discloses, poly urethanes resin film containing porous particles composed mainly of S i 0 2 There has been proposed a method of processing a fiber structure in which a water repellent having a perfluoroalkyl group is added to the formed fiber structure. However, the purpose of both of these inventions is to obtain a waterproof fabric having air permeability and moisture permeability by using the fine pores of the particles in the polyurethane resin as channels for air and steam. However, there is no suggestion about a coating film that can actually prevent contamination by a disperse dye. DISCLOSURE OF THE INVENTION The present invention relates to a polyester fiber coated fabric which captures a disperse dye with porous inorganic fine particles having fine pores having a specific pore size, transfers the dye from a fabric surface to another fabric surface, and reduces contamination. It is intended to provide a manufacturing method.
本発明におけるポリエステル繊維構造物とは、 ポリエ ステル 1 0 0 %の織編物、 不織布はもとより、 ポリエス テル繊維を必須とする混紡、 混繊、 交撚、 交織、 交編等 いずれに対しても可能であり特に限定されるものではな いが、 分散染料で染色されたもので、 特にポリエステル 1 0 0 %又はポリエステル高率混においてその効果が顕 ¾■ (？ある。  The polyester fiber structure in the present invention is applicable to any of polyester 100% woven and knitted fabrics, non-woven fabrics, blended yarns, blended fibers, twisted twists, twisted weaves, twisted weaves, etc. which require polyester fibers. Although it is not particularly limited, it is dyed with a disperse dye, and its effect is particularly apparent when the content of polyester is 100% or a high percentage of polyester is mixed.
本発明に用いる多孔性無機微粒子と しては、 二酸化ケ ィ素、 酸化チタ ン、 酸化ジルコニウム、 酸化アルミニゥ ム、 活性炭等等が用い得るが、 中でも二酸化ケイ素が効 果 · 実用性の点で最も有効に用いられる。  As the porous inorganic fine particles used in the present invention, silicon dioxide, titanium oxide, zirconium oxide, aluminum oxide, activated carbon, and the like can be used. Among them, silicon dioxide is the most effective and practical. Used effectively.
多孔性無機微粒子中の微細孔径の大きさは、 移行染料 の吸着効果に大き く影響する。 このため、 1 5 0 Aより 小さいものが用いられる。 好ま しく は 1 0 A〜 1 0 O A が効果の点で良い。 1 5 O Aより大きいと、 移行染料の 吸着保持が十分でない。  The size of the fine pores in the porous inorganic fine particles greatly affects the adsorption effect of the migrating dye. For this reason, those smaller than 150 A are used. Preferably, 10 A to 10 O A is good in terms of effect. If it is greater than 15 OA, the retention of the migration dye is not sufficient.
多孔性無機微粒子の有する表面積は 2 0 O nf / g以上 が好ま しく、 更に好ま しく は 5 0 0 nfノ g以上が良い。 表面積が 2 0 0 nf Z g未満では効果が不十分である。 本発明に用いる樹脂としては、 ウレタ ン系、 アク リル 系、 シリ コン系、 塩化ビニル系、 酢酸ビニル系、 など一 般のコ一ティ ング加工に使用される各種樹脂を自由に選 択することができる。 The surface area of the porous inorganic fine particles is preferably 20 Onf / g or more, and more preferably 500 Onf / g or more. If the surface area is less than 200 nf Z g, the effect is insufficient. As the resin to be used in the present invention, various resins used in general coating processing such as urethane, acrylic, silicon, vinyl chloride, and vinyl acetate can be freely selected. Can be.
次に本発明におけるコーティ ング加工布の製造方法に ついて述べる。  Next, a method of manufacturing a coated work cloth according to the present invention will be described.
第 1に、 コーティ ング前に多孔性無機微粒子を繊維表 面に付着させる方法と、 第 2に、 コ一ティ ング樹脂被膜 中に多孔性無機微粒子を含ませる方法がある。  First, there is a method of attaching porous inorganic fine particles to the fiber surface before coating, and second, a method of including porous inorganic fine particles in the coating resin film.
第 1の方法、 つまりコ一ティ ング前に多孔性無機微粒 子を繊維表面に付着させる方法について説明する。 この 方法の効果を十分発揮させるためには、 繊維表面に多孔 性無機微粒子を均一に付着させることが重要で、 取扱い- 作業性の面から水分散系多孔性無機微粒子をパディ ング により付着させるのが好ま しい。 パディ ング後の乾燥温 度は 8 0 °C〜 1 6 0° (：、 好ま しく は 1 0 0°C〜 1 3 0 °C の範囲で行なうのが良く、 1 6 0 °Cを超えると効果が低 下する。 多孔性無機微粒子の付着量は、 布帛重量に対し て 0. 5〜 1 5重量％が好ま しく、 より好ま しく は 1. 5〜 1 0重量％である。  The first method, that is, a method of attaching porous inorganic fine particles to the fiber surface before coating will be described. In order to fully exhibit the effect of this method, it is important to attach the porous inorganic fine particles uniformly to the fiber surface.From the viewpoint of handling and workability, it is necessary to attach the water-dispersed porous inorganic fine particles by padding. Is preferred. Drying temperature after padding should be in the range of 80 ° C to 160 ° C (: preferably in the range of 100 ° C to 130 ° C, if it exceeds 160 ° C The effect of the porous inorganic fine particles is preferably 0.5 to 15% by weight, more preferably 1.5 to 10% by weight, based on the weight of the fabric.
また使用する多孔性無機微粒子の粒子の大きさと して は、 1〜 1 0 0 ミ リ mの範囲のものを使う ことができ るが、 通常 1 0〜 5 0 ミ リ のものが好ま しく用いら れ O  The size of the porous inorganic fine particles to be used may be in the range of 1 to 100 millimeters m, but usually 10 to 50 millimeters is preferred. Ore
繊維表面に付着した多孔性無機微粒子の耐久性を向上 させる目的で通常の仕上用樹脂と併用して用いる方法が 好ま しく使用できる。 Improves the durability of porous inorganic fine particles attached to the fiber surface For this purpose, a method used in combination with a normal finishing resin can be preferably used.
第 2の方法は、 予めコーティ ング用の樹脂中に多孔性 無機微粒子を分散せしめるもので、 その場合は使用する 粒子の大きさは最大 1 5 mで小さい方が良い。 この方 法では、 樹脂中の多孔性無機微粒子の分散が良いことが 重要であり、 粒子の凝集は、 汚染防止効果の低下および コ一ティ ング品位を悪化する原因になる。  The second method is to disperse porous inorganic fine particles in a coating resin in advance. In this case, the size of the particles used is preferably as small as 15 m at the maximum. In this method, it is important that the porous inorganic fine particles are well dispersed in the resin, and the aggregation of the particles causes a decrease in the pollution prevention effect and a deterioration in the coating quality.
第 2の方法では、 多孔性無機微粒子を樹脂被膜中に層 状に偏在させる方法もある。 たとえば、 第 1図に示すよ うに多孔性無機微粒子が高濃度に層状分散した樹脂層 A と多孔性無機微粒子が少ないかそれを含まない樹脂層 B からなるような層状構造を有している場合である。  In the second method, there is a method in which porous inorganic fine particles are unevenly distributed in a layer in a resin film. For example, as shown in FIG. 1, a case where the resin has a layered structure composed of a resin layer A in which porous inorganic fine particles are dispersed in a layered manner at a high concentration and a resin layer B containing few or no porous inorganic fine particles. It is.
具体的には、 高濃度の多孔性無機微粒子を含有する樹 脂層と して、 樹脂の固型分重量に対して 1 0 %以上の多 孔性無機微粒子を含有する樹脂液 Aと、 多孔性無機微粒 子が全く含有しないかまたは 1 0 %未満の多孔性無機微 粒子を含有する樹脂液 Bを作成する。 塗布の順序と して は、 第 1図の繊維層 4の 1層目 1 に樹脂液 B、 2層目 2 に樹脂液 Aをコーティ ングするかまたはこの逆の方法が ある。 また、 3層構造にコーティ ングする場合は、 第 1 図の 1， 2， 3層目のいずれかに樹脂液 Aをコーティ ン グし、 他の 2層には樹脂液 Bをコーティ ングする。 なお 上記 2層構造または 3層構造にコーティ ングするに際し、 樹脂液 Aを 1層目 1 にコーティ ングした場合、 繊維との 接着性が低下することがあり、 接着性を特に要求される 場合は、 2層目 2または 3層目 3にコーティ ングするの が望ましい。 更に多孔性無機微粒子が高濃度に層状分散 した樹脂層 Aの厚みは 3 m以上有していることが望ま しい。 コ ーティ ング方法は、 特に限定されるものではな い。 特に、 高濃度の多孔性無機微粒子をコーティ ング用 の樹脂中に層状に介在せしめる方法においては、 高濃度 の多孔性無機微粒子が繊維から樹脂被膜内を移行する染 料をすベて捕集するとともに、 多孔性無機微粒子の微細 孔内に吸着保持するので、 染料の移行を恒久的に防止す る効果を示すのである。 図面の簡単な説明 第 1図は本発明の実施例 4で得られたポリエステル; 維コーティ ング加工布の一例を示す断面図である。 Specifically, as a resin layer containing a high concentration of porous inorganic fine particles, a resin solution A containing 10% or more of porous inorganic fine particles with respect to the solid content of the resin; A liquid resin B containing no inorganic fine particles at all or containing less than 10% of porous inorganic fine particles is prepared. As the order of application, the resin liquid B is coated on the first layer 1 of the fiber layer 4 and the resin liquid A is coated on the second layer 2 of FIG. 1, or the reverse method. When coating in a three-layer structure, apply resin solution A to one of the first, second, and third layers in Fig. 1, and apply resin solution B to the other two layers. When the resin liquid A is coated on the first layer 1 when coating the above two-layer structure or three-layer structure, Adhesion may decrease, and if adhesion is particularly required, it is desirable to coat the second layer 2 or the third layer 3. Further, the thickness of the resin layer A in which the porous inorganic fine particles are dispersed in a layered manner at a high concentration is desirably at least 3 m. The coating method is not particularly limited. In particular, in a method in which high-concentration porous inorganic fine particles are interposed in a resin layer for coating in a layered manner, the high-concentration porous inorganic fine particles collect all dyes that migrate from the fibers into the resin coating. At the same time, since it is adsorbed and held in the fine pores of the porous inorganic fine particles, the effect of permanently preventing the transfer of the dye is exhibited.
