Description
本発明はアルカリ減量や糸加工時の摩擦等における光触媒酸化物粒子の脱落を抑制し、かつ光触媒酸化物粒子の光触媒作用による樹脂の劣化を抑制することで長期間にまたがり、布帛の強力を維持し、ユニフォーム用途等へ応用可能な高耐久性、高品質の消臭性ポリエステル繊維に関するものである。 The present invention maintains the strength of the fabric over a long period of time by suppressing the fall of the photocatalytic oxide particles due to alkali weight loss, friction during yarn processing, etc., and suppressing the deterioration of the resin due to the photocatalytic action of the photocatalytic oxide particles. In addition, the present invention relates to a highly durable and high quality deodorant polyester fiber that can be applied to uniforms and the like.
近年、家庭やオフィス、病院などの生活環境において様々な悪臭や有害成分に対する関心が高まっており、これら臭気・有害成分にはアンモニアやアミン化合物等の窒素含有化合物、メチルメルカプタンや硫化水素等の硫黄含有化合物、そしてホルムアルデヒド、アセトアルデヒド等のアルデヒド類、低級脂肪酸類等がある。 In recent years, there has been an increasing interest in various bad odors and harmful components in living environments such as homes, offices and hospitals. These odors and harmful components include nitrogen-containing compounds such as ammonia and amine compounds, sulfur such as methyl mercaptan and hydrogen sulfide. There are contained compounds, aldehydes such as formaldehyde and acetaldehyde, lower fatty acids and the like.
このような種々異なる臭気成分を有効かつ長期に渡り除去するため、種々の消臭繊維が提案されている。例えば、吸着剤を担持させた繊維が提案されている。しかし、このような消臭繊維は吸着剤の吸着容量に限界があり、飽和状態になると消臭効果が消滅する。 In order to remove such various odor components effectively and over a long period of time, various deodorizing fibers have been proposed. For example, a fiber carrying an adsorbent has been proposed. However, such a deodorizing fiber has a limit in the adsorption capacity of the adsorbent, and the deodorizing effect disappears when saturated.
一方、このような欠点を解消すべく、光触媒粒子を活用して臭気成分を光触媒活性により繰り返し分解させる消臭繊維が提案されている。特開平１０−１８７９号公報にはシリコーン樹脂を架橋剤に用い、光触媒酸化チタンを布帛に固定する方法が提案されている。しかしながら、このように粒子固定した場合は耐久性に乏しく、特に肌着やシャツ、靴下等のインナーやユニフォーム等の洗濯耐久性を要求される用途では安定した消臭性能を長期間得ることは困難である。 On the other hand, in order to eliminate such drawbacks, deodorant fibers have been proposed in which photocatalyst particles are used to repeatedly decompose odor components by photocatalytic activity. Japanese Patent Application Laid-Open No. 10-1879 proposes a method of fixing photocatalytic titanium oxide to a fabric using a silicone resin as a crosslinking agent. However, when particles are fixed in this way, the durability is poor, and it is difficult to obtain a stable deodorizing performance for a long period of time, especially in applications that require washing durability such as underwear, shirts, socks, etc. is there.
また最近では耐久性を付与するために、樹脂の内部へ光触媒粒子を練り込むことが検討されている。更には光照射がない場合にも性能を維持するために吸着剤と併用した消臭繊維が提案されている（特許文献１参照）。しかしながら、光触媒粒子は樹脂自体も分解するため、長期に渡り安定した消臭性能と品質・品位を得ることが出来ず、展開用途を限定せざるを得なかった。
本発明は上述の問題を解決し、高耐久性な消臭性能を有すとともに、樹脂の経時劣化がなく、広範囲において用途展開可能な高耐久性、高品質の消臭性ポリエステル繊維に関するものである。 The present invention relates to a highly durable, high-quality deodorant polyester fiber that solves the above-mentioned problems, has a highly durable deodorizing performance, does not deteriorate with time, and can be used in a wide range of applications. is there.
上記の課題を解決するために鋭意研究した結果、光触媒酸化物粒子を含有するポリエチレンテレフタレート繊維であって、残留伸度が３０〜２００％であることを特徴とする消臭性ポリエステル繊維によって、本発明の目的を達成できる。 As a result of earnest research to solve the above-mentioned problems, the present invention is a polyethylene terephthalate fiber containing photocatalytic oxide particles, which has a residual elongation of 30 to 200%. The object of the invention can be achieved.
本発明はアルカリ減量や糸加工時の摩擦等における光触媒酸化物粒子の脱落を抑制し、かつ光触媒酸化物粒子の光触媒作用による樹脂の劣化を抑制することで長期間にまたがり、布帛の強力を維持し、特に布帛強力を要求されるユニフォーム用途等へも応用可能な高耐久性、高品質の消臭性ポリエステル繊維を得ることが出来る。 The present invention maintains the strength of the fabric over a long period of time by suppressing the fall of the photocatalytic oxide particles due to alkali weight loss, friction during yarn processing, etc., and suppressing the deterioration of the resin due to the photocatalytic action of the photocatalytic oxide particles. In addition, it is possible to obtain a highly durable and high quality deodorant polyester fiber that can be applied to uniforms and the like that require particularly strong fabric strength.
以下、本発明について詳細に説明する。 Hereinafter, the present invention will be described in detail.
本発明の消臭性ポリエステル繊維は、光触媒酸化物粒子を含有するポリエチレンテレフタレートであることが重要である。光触媒酸化物粒子を含有するポリエチレンテレフタレートであることで臭気成分を無臭気物質に分解し、消臭効果を発現する。 It is important that the deodorant polyester fiber of the present invention is polyethylene terephthalate containing photocatalytic oxide particles. By being a polyethylene terephthalate containing photocatalytic oxide particles, the odor component is decomposed into an odorless substance, and an odor eliminating effect is exhibited.
なお、本発明の光触媒酸化物粒子の具体例としては、ＴｉＯ2やＳｒＴｉＯ3、ＺｒＯ、ＳｎＯ2、ＷＯ3、Ｂｉ2Ｏ3、Ｆｅ2Ｏ3等が挙げられるが、特にＴｉＯ2が好ましく、より好ましくはアナターゼ型ＴｉＯ2を含有することが好ましい。 In addition, specific examples of the photocatalytic oxide particles of the present invention include TiO 2 , SrTiO 3 , ZrO, SnO 2 , WO 3 , Bi 2 O 3 , Fe 2 O 3, etc., but TiO 2 is particularly preferable, More preferably, it contains anatase TiO 2 .
本発明の消臭性ポリエステル繊維は残留伸度が３０〜２００％であることが重要である。
残留伸度が３０％以上であることで製糸性の安定化や原糸、布帛を高品位で得ることが出来る。また残留伸度が２００％以下であることで、光触媒酸化物粒子が消臭性ポリエステル繊維表面側に集中し、光触媒酸化物粒子の含有量を極少化することが可能であり、光触媒酸化物粒子のコストダウンのみならず、消臭性能の向上やポリエチレンテレフタレートの経時劣化を抑制することが出来る。より好ましくは４０〜１８０％である。
It is important that the deodorant polyester fiber of the present invention has a residual elongation of 30 to 200%.
When the residual elongation is 30% or more, it is possible to stabilize the spinning property and to obtain the raw yarn and the fabric with high quality. Further, when the residual elongation is 200% or less, the photocatalyst oxide particles are concentrated on the deodorant polyester fiber surface side, and the content of the photocatalyst oxide particles can be minimized. In addition to the cost reduction, it is possible to improve the deodorization performance and suppress the deterioration of polyethylene terephthalate over time. More preferably, it is 40 to 180%.
本発明において残留伸度は紡糸温度と紡糸速度によって制御することが出来、紡速２０００〜５０００ｍ／ｍｉｎで紡糸することが好ましい。 In the present invention, the residual elongation can be controlled by the spinning temperature and spinning speed, and it is preferable to spin at a spinning speed of 2000 to 5000 m / min.
なお、本発明の残留伸度とは紡糸巻き取り糸を測定したものであり、東洋ボールドウィン社製テンシロン引張試験機を用い、測定条件は試料長５ｃｍ、引張速度４０ｃｍ／ｍｉｎで測定し、測定回数５回の平均値で評価した。 The residual elongation of the present invention is a value measured by measuring the wound and wound yarn. Using a Tensilon tensile tester manufactured by Toyo Baldwin, the measurement conditions were a sample length of 5 cm and a tensile speed of 40 cm / min. Evaluation was made with an average value of 5 times.
本発明の消臭性ポリエステル繊維は消臭性能の安定性および製糸性の兼ね合いから光触媒酸化物粒子の平均２次粒子径が０．１〜３．０μｍであることが好ましい。平均２次粒子径が０．１μｍ以上であることで消臭性ポリエステル繊維に含有する光触媒酸化物粒子の凝集を抑制し、安定した製糸が可能となる。一方、平均２次粒子径が３．０μｍ以下であることで粗大粒子混入による製糸性不良を回避でき、また光触媒酸化物粒子の表面積が増大するため光触媒活性が高効率化し、消臭性能を効果的に発現させることが出来る。また、より好ましい平均２次粒子径は０．３〜１．５μｍであり、単糸細繊度製糸の際には製糸性面でより効果的である。なお、本発明の平均２次粒子径とは堀場製作所社製、粒径分布測定器ＬＡ−７００(分散媒：メタノール、透過率８０％になるように濃度を調整)を用いて測定した。 In the deodorant polyester fiber of the present invention, the average secondary particle diameter of the photocatalyst oxide particles is preferably 0.1 to 3.0 μm in view of the stability of the deodorization performance and the yarn forming property. When the average secondary particle diameter is 0.1 μm or more, aggregation of the photocatalyst oxide particles contained in the deodorant polyester fiber is suppressed, and stable yarn production becomes possible. On the other hand, when the average secondary particle size is 3.0 μm or less, it is possible to avoid poor yarn production due to mixing of coarse particles, and the surface area of the photocatalytic oxide particles is increased, so that the photocatalytic activity is highly efficient and the deodorizing performance is effective Can be expressed. Moreover, a more preferable average secondary particle diameter is 0.3 to 1.5 μm, and it is more effective in terms of the yarn-forming property in the case of single yarn fineness yarn production. The average secondary particle size of the present invention was measured using a particle size distribution measuring instrument LA-700 (dispersion medium: methanol, concentration adjusted to 80% transmittance) manufactured by Horiba, Ltd.
本発明の消臭性ポリエステル繊維に含有する光触媒酸化物粒子の含有量は繊維内重量比率で０．５〜５．０重量％であることが好ましい。含有量を０．５重量％以上とすることで消臭効果が安定し、一方５．０重量％以下ですることでポリエチレンテレフタレートの光触媒劣化を緩和することが出来る。より好ましくは光触媒酸化物粒子の含有量は繊維内重量比率で１．０〜３．０重量％である。 The content of the photocatalytic oxide particles contained in the deodorant polyester fiber of the present invention is preferably 0.5 to 5.0% by weight in the fiber. When the content is 0.5% by weight or more, the deodorizing effect is stabilized. On the other hand, when the content is 5.0% by weight or less, photocatalytic deterioration of polyethylene terephthalate can be alleviated. More preferably, the content of the photocatalytic oxide particles is 1.0 to 3.0% by weight in terms of the weight ratio in the fiber.
本発明の消臭性ポリエステル繊維は光触媒酸化物粒子に多孔質物質で皮膜を形成することが好ましい。光触媒酸化物粒子はその光触媒活性によりポリエステル樹脂自体も分解するため、多孔質物質で光触媒酸化物粒子の表面に皮膜を形成し、光触媒酸化物粒子とポリエステル樹脂の接触面積を極小化することで布帛強力の経時劣化を緩和出来る。なお、多孔質物質の具体例としては、Ｃａ3（ＰＯ4）2、ＳｉＯ2、Ａｌ2Ｏ3等の無機化合物やテフロン(Ｒ)樹脂やシリコン樹脂等が挙げられるが、好ましくはＣａ3（ＰＯ4）2である
本発明の消臭性ポリエステル繊維の断面形状は特に限定されるものではなく、丸断面以外に異型断面化しても良い。異型断面化することにより、３葉断面化による光沢感や４葉以上の多葉断面化による吸水性や速乾性能、中空断面化によるハリコシ感や保温性、軽量感などの機能性を付与させることが出来、その上、消臭性ポリエステル繊維の表面積が増大するため、臭気成分との接触面積が増大し、消臭性能が向上する。また、本発明の目的を損なわない限り、必要に応じてイソフタル酸、２，２−ビス｛４−(β−ヒドロキシエトキシ)フェニル｝プロパン等の共重合成分や、ヒンダートフェノール系化合物等の酸化防止剤、その他無機粒子を併有しても良い。
The deodorant polyester fiber of the present invention preferably forms a film on the photocatalytic oxide particles with a porous substance. Since the photocatalytic oxide particles also decompose the polyester resin itself due to the photocatalytic activity, a film is formed on the surface of the photocatalytic oxide particles with a porous material, and the contact area between the photocatalytic oxide particles and the polyester resin is minimized. Powerful deterioration over time can be alleviated. Specific examples of the porous material include inorganic compounds such as Ca 3 (PO 4 ) 2 , SiO 2 , and Al 2 O 3 , Teflon (R) resin, silicon resin, and the like, preferably Ca 3 ( PO 4 ) 2 The cross-sectional shape of the deodorant polyester fiber of the present invention is not particularly limited, and may be an irregular cross-section other than a round cross-section. By making the cross section atypical, functionality such as glossiness due to cross-section of three leaves, water absorption and quick-drying performance due to cross-section of four or more leaves, and crispness, heat retention and lightness due to hollow cross-section are given. Moreover, since the surface area of the deodorant polyester fiber is increased, the contact area with the odor component is increased and the deodorization performance is improved. In addition, as long as the object of the present invention is not impaired, copolymerization components such as isophthalic acid and 2,2-bis {4- (β-hydroxyethoxy) phenyl} propane, and oxidation of hindered phenol compounds, etc. You may have an inhibitor and other inorganic particles together.
