The required characteristics differ depending on the application. For example, in applications such as inner garments, sports garments, and medical-related uniforms that work in light clothing, it is required to satisfy excellent permeation resistance.
特許文献１では、酸化チタン艶消し剤を１．０重量％以上含むポリエステルで芯部を形成し、含金属リン化合物とアルカリ土類金属化合物とを含有するポリエステルで鞘部を形成し該鞘部にアルカリ減量加工を施すことにより微細孔をもうけた複合繊維が提案されている。かかる複合繊維において、酸化チタン艶消し剤と微細孔の効果である程度防透性は改善されるものの尚不十分であった。 In patent document 1, a core part is formed with polyester containing 1.0% by weight or more of a titanium oxide matting agent, and a sheath part is formed with polyester containing a metal-containing phosphorus compound and an alkaline earth metal compound. There has been proposed a composite fiber having fine pores formed by subjecting to an alkali weight reduction process. In such a composite fiber, although the permeability is improved to some extent by the effect of the titanium oxide matting agent and the fine pores, it is still insufficient.
又 特許文献２では芯部に５％以上の酸化チタン等の艶消剤を含む複合ポリエステル繊維を提案しているが、十分な性能を得るためには、結局艶消剤を多量に添加せざるをえず、又芯成分比率を高める必要があるため、糸の脆性が悪化し強伸度の劣ったものとなるばかりでなく、製糸工程での歩留も悪いものとなる。
本発明は、防透性ポリエステル繊維に関し、特に繊維表面の平滑性が良好で、製糸時、得られた繊維の成形加工時あるいは繊維成形品の使用時に接触するローラー、ガイド等の付属品の摩耗を抑制し、また破断強伸度の良好な防透性ポリエステル繊維に関するものである。 The present invention relates to a non-permeable polyester fiber, and in particular, the surface of the fiber has good smoothness, and wear of accessories such as a roller and a guide that are in contact with each other at the time of yarn production, molding of the obtained fiber, or use of a fiber molded product.

以下、本発明の実施の形態について詳細に説明する。
本発明で用いられるポリエステルは、主たる繰り返し単位がエチレンテレフタレートからなるポリエステルを主たる対象とする。しかしながら、テレフタル酸成分及び／又はエチレングリコール成分以外の第３成分を少量（通常はテレフタル酸成分に対して２０モル％以下）共重合したものであっても良い。芯成分、鞘成分ともにポリエステルであることが好ましい。
Hereinafter, embodiments of the present invention will be described in detail.
The polyester used in the present invention is mainly a polyester whose main repeating unit is ethylene terephthalate. However, a small amount (usually 20 mol% or less of the terephthalic acid component) of a third component other than the terephthalic acid component and / or the ethylene glycol component may be copolymerized. Both the core component and the sheath component are preferably polyester.
尚、該ポリエステルは、本発明の効果を阻害しない範囲で、必要に応じて少量の添加剤、例えば滑剤、顔料、染料、酸化防止剤、固相重合促進剤、蛍光増白剤、帯電防止剤、紫外線吸収剤、光安定剤、熱安定剤、遮光剤、又は艶消剤等を含んでも良い。 The polyester has a small amount of additives such as a lubricant, a pigment, a dye, an antioxidant, a solid phase polymerization accelerator, a fluorescent whitening agent, and an antistatic agent as long as the effects of the present invention are not impaired. , UV absorbers, light stabilizers, heat stabilizers, shading agents, matting agents, and the like.
本発明のポリエステル繊維は繊維軸と直交する断面における芯成分の形状が３〜５個の鋭突部を有する異型断面形状である酸化チタンを１０％以上含有する芯成分と、該芯成分を完全に被覆する繊維形成性ポリマーからなる鞘成分とにより構成される事が必要である。本発明のポリエステル繊維は側面から見た際の光の干渉効果を利用するものであり、図３に示すように、側面から見た芯成分の面積比率は、どの側断面から見てもほぼ同様である必要がある。その為芯成分の鋭突部が３個未満であると側面から見た際に大きく透ける角度が必ず生じ糸斑状に見え易くなる。鋭突部が３個以上では実質的に差は少ないが、５個を超える鋭突部があると繊維強度が低下しやすい問題が生じる。また本発明の目的上、特に加工工程での平滑性に問題のない鞘成分によって該芯成分を完全に被覆されていなければならない。一部でも高濃度の酸化チタンを含む芯成分が糸表層に露出していると、その部分に接触した糸ガイドを磨耗させるだけでなく、露出面から剥離を起こし、糸が割れ易くなる。 The polyester fiber of the present invention comprises a core component containing 10% or more of a titanium oxide having a cross-sectional shape of 3 to 5 with a core portion in a cross section perpendicular to the fiber axis, and a complete cross-section of the core component. It is necessary to be constituted by a sheath component made of a fiber-forming polymer to be coated. The polyester fiber of the present invention utilizes the light interference effect when viewed from the side, and as shown in FIG. 3, the area ratio of the core component viewed from the side is substantially the same from any side cross section. Need to be. For this reason, when the number of sharp protrusions of the core component is less than 3, an angle that is greatly transparent when viewed from the side surface is inevitably generated, and it becomes easy to look like a thread spot. If the number of sharp protrusions is three or more, the difference is substantially small, but if there are more than five sharp protrusions, there is a problem that the fiber strength tends to decrease. Further, for the purpose of the present invention, the core component must be completely covered with a sheath component which has no problem in smoothness particularly in the processing step. When a core component containing even a high concentration of titanium oxide is exposed on the yarn surface layer, not only does the yarn guide in contact with the portion wear, but also peeling occurs from the exposed surface and the yarn is easily broken.
また本発明のポリエステル繊維の芯成分は、図３に示す繊維軸と直交する断面における芯成分の鋭突部の先端を外周とした直径Ａが糸断面直径Ｂに対して以下の式を満足する必要がある。０．７≦Ａ／Ｂ≦０．９
ここでＡ／Ｂが０．７以下であると側面から見た際に表層側で光が透け易く、透け感が残る事から十分な防透性能があるとはいえない。Ａ／Ｂが０．９以上であると、鞘成分による被覆が十分でなく、洗濯などの機械的力により被覆が破れ、糸が割れやすくなる欠点をもったものとなる。
Further, the core component of the polyester fiber of the present invention has a diameter A with the tip of the sharp protrusion of the core component in the cross section orthogonal to the fiber axis shown in FIG. There is a need. 0.7 ≦ A / B ≦ 0.9
Here, when A / B is 0.7 or less, light is easily transmitted on the surface layer side when viewed from the side surface, and it cannot be said that there is a sufficient anti-permeability performance because a transparent feeling remains. When A / B is 0.9 or more, coating with the sheath component is not sufficient, and the coating is broken by mechanical force such as washing, and the yarn is easily broken.
本発明のポリエステル繊維の芯成分に含まれる酸化チタンは公知の酸化チタンを用いることができるが、一次粒子径が１．０μｍ以下の二酸化チタンが紡糸時の目詰まりが少なく好ましい。 As the titanium oxide contained in the core component of the polyester fiber of the present invention, known titanium oxide can be used, but titanium dioxide having a primary particle diameter of 1.0 μm or less is preferable because clogging during spinning is small.
ポリエステル繊維の芯成分に含まれる酸化チタンの濃度は１０％以上であることが望ましい。一般的に酸化チタンの濃度が高いほど高い防透性を発現することは自明であるが、従来の酸化チタンの混合紡糸方式では摩耗の問題から添加できる量は高々数％程度であり１０％以上添加することは極めて困難であった。本発明では１０％以上の濃度で酸化チタンを用いることができるので従来にない優れた防透性能をもったポリエステル繊維を提供することができる。 The concentration of titanium oxide contained in the core component of the polyester fiber is desirably 10% or more. In general, it is obvious that the higher the titanium oxide concentration, the higher the permeation resistance. However, in the conventional titanium oxide mixed spinning method, the amount that can be added is at most several percent due to wear, and more than 10%. It was very difficult to add. In the present invention, since the titanium oxide can be used at a concentration of 10% or more, it is possible to provide a polyester fiber having an excellent non-permeability performance.
酸化チタンを含有させる方法としてはポリエステル重合時又はチップ化前に酸化チタンを添加する方法、酸化チタンを含むマスターチップを予め作っておき紡糸時にベースポリマーにチップ状態或いは溶融状態でブレンドする方法等一般的な方法で行うことが出来る。 As a method of containing titanium oxide, a method of adding titanium oxide at the time of polyester polymerization or before chip formation, a method of preparing a master chip containing titanium oxide in advance and blending it into a base polymer in a chip state or a molten state at the time of spinning, etc. Can be done in a traditional way.
本発明のポリエステル繊維の芯成分は繊維全体重量に対して０．１〜２０％であることが好ましい。より好ましくは１０〜２０％である。２０％を超える場合、芯成分が高濃度の酸化チタンを含む為、繊維全体として強伸度の低い繊維となる。本発明のポリエステル繊維の芯成分が、図３に示す繊維軸と直交する断面における芯成分の各鋭突部の先端を外周とした直径Ａが繊維断面直径Ｂに対して、０．７≦Ａ／Ｂ≦０．９を満足する場合、芯成分が繊維全体の２０％以下の量であっても芯成分に使用する酸化チタンの良好な白度、防透性は維持される。このようにして繊維強度と防透性を両立させることが出来る。 The core component of the polyester fiber of the present invention is preferably 0.1 to 20% based on the total weight of the fiber. More preferably, it is 10 to 20%. When it exceeds 20%, the core component contains high-concentration titanium oxide, so that the fiber as a whole has low strength and elongation. The core component of the polyester fiber of the present invention has a diameter A with the tip of each sharp protrusion of the core component in the cross section orthogonal to the fiber axis shown in FIG. When /B≦0.9 is satisfied, good whiteness and permeation resistance of the titanium oxide used for the core component are maintained even if the core component is 20% or less of the total fiber. In this way, both fiber strength and permeation resistance can be achieved.
また本発明に用いる鞘成分ポリマーは前述の如く、本発明の目的を阻害しない範囲において 共重合ポリマーを使用しても、滑剤や艶消剤などを添加していても良い。ただし、酸化チタン等 硬質の添加剤の過度な添加は 本発明の目的であるところの耐摩耗性の観点で好ましくなく、濃度は５．０％以下にすることが必要である。 As described above, the sheath component polymer used in the present invention may be a copolymerized polymer or a lubricant or a matting agent may be added as long as the object of the present invention is not impaired. However, excessive addition of hard additives such as titanium oxide is not preferable from the viewpoint of wear resistance, which is the object of the present invention, and the concentration needs to be 5.0% or less.
