Description
本発明は、抗菌性および消臭性を有する芯鞘型ポリエステル複合繊維に関する。 The present invention relates to a core-sheath type polyester composite fiber having antibacterial and deodorant properties.
従来、抗菌性を有するポリエステル布帛としては、無機系抗菌剤を繊維中に練り込んだ抗菌性ポリエステル繊維で布帛を構成したもの、後加工により無機系抗菌剤を布帛に付与したもの、後加工により天然系抗菌剤を布帛に付与したものなど、種々のものが提案されている（例えば、特許文献１、特許文献２、特許文献３参照）。 Conventionally, as a polyester fabric having antibacterial properties, a fabric composed of an antibacterial polyester fiber in which an inorganic antibacterial agent is kneaded into the fiber, a fabric obtained by applying an inorganic antibacterial agent to the fabric by post-processing, and post-processing Various things, such as what gave a natural system antibacterial agent to cloth, are proposed (for example, refer to patent documents 1, patent documents 2, patent documents 3).
しかしながら、無機系抗菌剤を繊維中に練り込んだものでは繊維の色調が悪くなるという問題があった。また、銀イオンや亜鉛イオンなどを含む無機系抗菌剤やキトサンなどを含む天然系抗菌剤を後加工により布帛に付与したものでは耐久性の問題があった。さらには、銀イオンや亜鉛イオンなどを含む無機系抗菌剤を使用する場合には、環境上の問題もあった。 However, when the inorganic antibacterial agent is kneaded into the fiber, there is a problem that the color tone of the fiber is deteriorated. In addition, there was a problem of durability in the case where an inorganic antibacterial agent containing silver ions or zinc ions or a natural antibacterial agent containing chitosan was applied to the fabric by post-processing. Furthermore, when using an inorganic antibacterial agent containing silver ions, zinc ions, etc., there are also environmental problems.
また、特に近年、織編物の風合い、肌触り、外観等に関する要求がますます高まってきており、単糸繊度が２．０ｄｔｅｘ以下の、細繊度のポリエステル仮撚加工糸を用いて柔らかな風合を有する布帛が製造されているが、上述のような抗菌剤を繊維中に練りこんだものは細繊度化が困難で、毛羽等、品質面の問題があり、これまで、スポーツ衣料、ユニフォーム、防塵衣、等の用途、あるいは、肌に直接触れることの多いブラウスやシャツなどの用途において、充分な抗菌性、消臭性と柔らかな風合を両立する布帛は皆無に等しいといっても過言ではないのが現状であった。 In particular, in recent years, there has been an increasing demand for the texture, texture, appearance, etc. of woven and knitted fabrics, and a soft texture using a fine yarn polyester twisted yarn with a single yarn fineness of 2.0 dtex or less. Fabrics with the above-mentioned antibacterial agents kneaded in the fiber are difficult to make finer, and have problems with quality such as fluff, so far, sports clothing, uniforms, dustproof It is an exaggeration to say that fabrics that have sufficient antibacterial and deodorant properties and a soft texture are almost none in applications such as clothing, or in blouse and shirts that often come into direct contact with the skin. There was no current situation.
このような現状に対し、本出願人は特許文献４、５において、芯鞘型の複合繊維の鞘部に特定のスルホン酸化合物を含むポリエステルを用い、それを酸性化処理することにより抗菌性と消臭性を有しながら耐久性にも優れる繊維を提案しているが、酸性化処理後に芯部と鞘部の剥離が起こり、強度保持が十分でなく品位にも劣るものとなるという欠点があった。 In contrast to this situation, the present applicants in Patent Documents 4 and 5 use a polyester containing a specific sulfonic acid compound in the sheath portion of the core-sheath-type composite fiber, and have an antibacterial property by acidifying it. Although it has proposed a fiber that has deodorant properties and excellent durability, there is a drawback that the core and the sheath are peeled after the acidification treatment, and the strength is not sufficiently maintained and the quality is inferior. there were.

本発明の芯鞘型ポリエステル複合繊維は上記の芯成分ポリエステルＡと鞘成分ポリエステルＢをチップ化し公知の芯鞘複合紡糸装置を用いて製造することができる。
ここで、ポリエステルＡのガラス転移温度（ＴｇＡ）は、ポリエステルＢのガラス転移温度（ＴｇＢ）に対し次式を満足することが必要である。ガラス転移温度はＤＳＣ（示差走査熱量測定）法による測定方法（昇温速度＝２０℃／分）で求めることができる。
ＴｇＡ≧ＴｇＢ−３℃
The core-sheath type polyester composite fiber of the present invention can be produced by converting the core component polyester A and the sheath component polyester B into chips and using a known core-sheath composite spinning device.
Here, it is necessary for the glass transition temperature (TgA) of polyester A to satisfy the following equation with respect to the glass transition temperature (TgB) of polyester B. The glass transition temperature can be determined by a measurement method (temperature increase rate = 20 ° C./min) by a DSC (differential scanning calorimetry) method.
TgA ≧ TgB-3 ° C
ここでポリエステルＡのガラス転移温度（ＴｇＡ）とポリエステルＢのガラス転移温度（ＴｇＢ）が上記式を満足しない場合は紡糸時に芯鞘の配向度差が顕著となり、後述する酸性化処理における鞘部の劣化が著しく起こる他、芯部の配向度が下がり、結果として芯部と鞘部の剥離を引き起こすこととなる。芯部と鞘部の剥離が起こると布帛とした際に、外観の斑の原因となり、著しく品位が低下する。さらには本発明の複合繊維の強度を担う芯部の配向度が低いと、酸性化処理後の繊維物性も劣るものとなる。 Here, when the glass transition temperature (TgA) of polyester A and the glass transition temperature (TgB) of polyester B do not satisfy the above formula, the difference in the orientation degree of the core-sheath becomes significant at the time of spinning. In addition to significant deterioration, the degree of orientation of the core part decreases, resulting in peeling of the core part and the sheath part. When the core part and the sheath part are peeled off, when used as a fabric, it causes a spot in appearance, and the quality is remarkably lowered. Furthermore, if the orientation degree of the core portion that bears the strength of the composite fiber of the present invention is low, the fiber physical properties after the acidification treatment are also inferior.
また、ポリエステルＡの融点（ｍｐＡ）とポリエステルＢの融点（ｍｐＢ）がｍｐＡ≧ｍｐＢを満足し、且つポリエステルＡの溶融粘度ηＡはポリエステルＢの溶融粘度ηＢの１．１倍以上であることが必要である。ポリエステルＡ、Ｂの融点はガラス転移温度と同様にＤＳＣ法により求めることができる。溶融粘度はフローテスターなど公知の方法で測定可能であり、紡糸時の温度における剪断速度２０００ｓ−１での溶融液の温度を指す。ポリエステルＡの融点とポリエステルＢの融点が上記式を満足しない場合は、芯鞘複合繊維の紡糸時に鞘部が先に固化し、芯部の配向が下がり酸性化処理時の芯部と鞘部の剥離の原因となり、酸性化処理後の繊維物性も劣るものとなる。また、ポリエステルＡの溶融粘度ηＡがポリエステルＢの溶融粘度ηＢの１．１倍未満の場合も同様である。 Further, the melting point (mpA) of polyester A and the melting point (mpB) of polyester B satisfy mpA ≧ mpB, and the melt viscosity ηA of polyester A needs to be 1.1 times or more the melt viscosity ηB of polyester B. It is. The melting points of polyesters A and B can be determined by the DSC method in the same manner as the glass transition temperature. The melt viscosity can be measured by a known method such as a flow tester, and indicates the temperature of the melt at a shear rate of 2000 s -1 at the spinning temperature. When the melting point of polyester A and the melting point of polyester B do not satisfy the above formula, the sheath part solidifies first when spinning the core-sheath composite fiber, the orientation of the core part is lowered, and the core part and sheath part at the time of acidification treatment It becomes a cause of peeling, and the fiber properties after the acidification treatment are also inferior. The same applies when the melt viscosity ηA of polyester A is less than 1.1 times the melt viscosity ηB of polyester B.

また本発明の芯鞘型ポリエステル複合繊維の芯成分と鞘成分の繊維軸に直交する断面における面積比は芯成分面積ＳＡ：鞘成分面積ＳＢ＝９５：５〜５０：５０であることが必要である。芯成分が５０未満の場合繊維強度が低下し好ましくない。また鞘成分が５未満の場合は抗菌性が低下し好ましくない。 Moreover, the area ratio in the cross section orthogonal to the fiber axis of the core component of the core-sheath-type polyester composite fiber of this invention and a sheath component needs to be core component area SA: sheath component area SB = 95: 5-50: 50. is there. When the core component is less than 50, the fiber strength is undesirably lowered. On the other hand, when the sheath component is less than 5, the antibacterial property decreases, which is not preferable.
