Description
本発明は、洗濯耐久性、吸水性、堅牢性に優れる消臭性繊維構造物、および該消臭性繊維構造物を用いてなる繊維製品に関する。 The present invention relates to a deodorant fiber structure excellent in washing durability, water absorption, and fastness, and a fiber product using the deodorant fiber structure.
近年、快適生活を目指した生活環境の多様化に伴い、匂いに対する関心が高まっている。そして、かかるニーズに応えるべく、ポリエステルなどの繊維形成能を有する熱可塑性高分子化合物と臭気を吸着する吸着剤を主成分とする繊維原料を溶融紡糸したものや、後加工においてポリウレタン系樹脂組成物やシリコーン系樹脂組成物を介して、ポリエステル繊維を含む布帛に消臭剤を付与したものなどが提案されている（例えば、特許文献１、２、３参照）。 In recent years, with the diversification of living environments aimed at comfortable living, interest in odors has increased. In order to meet such needs, a melt-spun fiber material mainly composed of a thermoplastic polymer compound having fiber-forming ability such as polyester and an adsorbent that adsorbs odor, and a polyurethane resin composition in post-processing In addition, a fabric including a polyester fiber and a deodorant added thereto via a silicone-based resin composition has been proposed (see, for example, Patent Documents 1, 2, and 3).
しかしながら、後加工により無機系消臭剤を付与した布帛において、消臭剤の汎用性はあるものの、ポリウレタン系樹脂組成物と構成繊維との接着性が弱く耐久性に問題があった。一方、耐久性を上げるためにシリコーン系樹脂を使用すると、洗濯により吸水性が大きく低下するという問題があった。また、消臭剤に含まれる分散剤や活性剤の影響で、分散染料で染色した布帛の染色堅牢度が低下するという問題があった。 However, in a fabric provided with an inorganic deodorant by post-processing, although the deodorant has general versatility, there is a problem in durability because the adhesion between the polyurethane resin composition and the constituent fibers is weak. On the other hand, when a silicone resin is used to increase the durability, there is a problem that the water absorption is greatly reduced by washing. In addition, there is a problem in that the fastness to dyeing of a fabric dyed with a disperse dye decreases due to the influence of a dispersant or an activator contained in the deodorant.
さらには、無機系加工剤で消臭加工を施した布帛は、石鹸で洗濯した際に、消臭剤の主成分である酸化亜鉛と石鹸が反応し布帛が白化するという問題があった。そのため、ユニフォーム、スポーツウエアなど高い耐洗濯性、吸水性、堅牢性を要求される分野に応用することが困難であった。 Furthermore, the fabric that has been deodorized with an inorganic processing agent has a problem that when the soap is washed with soap, zinc oxide, which is the main component of the deodorant, reacts with the soap and the fabric is whitened. For this reason, it has been difficult to apply to fields requiring high washing resistance, water absorption, and fastness, such as uniforms and sportswear.
本発明は上記の背景に鑑みなされたものであり、その目的は、洗濯耐久性、吸水性、堅牢性に優れる消臭性繊維構造物、および該消臭性繊維構造物を用いてなる繊維製品を提供することにある。 The present invention has been made in view of the above background, and its object is to provide a deodorant fiber structure excellent in washing durability, water absorption, and fastness, and a textile product using the deodorant fiber structure. Is to provide.
本発明者らは上記の課題を達成するため鋭意検討した結果、ポリエステル繊維を含む繊維構造物においてポリエステル繊維の単繊維繊度を小さくし、かつ有機系消臭剤を使用することにより、染色堅牢度の低下が少ない、洗濯耐久性、吸水性に優れた消臭性繊維構造物が得られることを見出し、さらに鋭意検討を重ねることにより本発明を完成するに至った。 As a result of intensive studies to achieve the above-mentioned problems, the present inventors have made it possible to reduce the single fiber fineness of the polyester fiber in the fiber structure containing the polyester fiber, and to use an organic deodorant, thereby improving the color fastness. The present inventors have found that a deodorant fiber structure excellent in washing durability and water absorption can be obtained, and has further intensively studied to complete the present invention.

Here, the polyester forming the polyester fiber has terephthalic acid as a main dicarboxylic acid component and at least one glycol, preferably at least one alkylene selected from ethylene glycol, trimethylene glycol, tetramethylene glycol and the like. Polyester containing glycol as the main glycol component. In the polyester, the third component may be modified by copolymerization and / or blending as necessary. Such polyester may be material-recycled or chemical-recycled polyester or polyethylene terephthalate using a monomer component obtained using biomass, that is, a biological material as a raw material. Furthermore, the polyester obtained using the catalyst containing the specific phosphorus compound and titanium compound which are described in Unexamined-Japanese-Patent No. 2004-270097 and 2004-21268 may be sufficient.
なお、かかるポリエステルには、必要に応じて任意の添加剤、例えば触媒、着色防止剤、耐熱剤、難燃剤、酸化防止剤、無機微粒子などが含まれていてもさしつかえない。
前記ポリエステル繊維において、繊維の表面積を大きくして優れた消臭性、洗濯耐久性、吸水性を得る上で、単繊維繊度５．０ｄｔｅｘ以下（好ましくは０．０００１〜１．５ｄｔｅｘ）であることが肝要である。単繊維繊度が５．０ｄｔｅｘよりも大きいと、消臭性、洗濯耐久性、吸水性などが低下するおそれがあり好ましくない。
Such a polyester may contain any additive as required, for example, a catalyst, an anti-coloring agent, a heat-resistant agent, a flame retardant, an antioxidant, inorganic fine particles and the like.
The polyester fiber has a single fiber fineness of 5.0 dtex or less (preferably 0.0001 to 1.5 dtex) in order to increase the surface area of the fiber to obtain excellent deodorant properties, washing durability and water absorption. Is essential. When the single fiber fineness is larger than 5.0 dtex, the deodorizing property, washing durability, water absorption and the like may be lowered, which is not preferable.

The polyester fiber may be a short fiber (spun yarn), but has a total fineness of 10 to 200 dtex and a filament number of 30 to 50,000 (more preferably 30 to 50,000) in order to obtain excellent deodorizing properties, washing durability and water absorption. 200) long fibers (multifilament) are preferable.
Such long fibers (multifilaments) may be subjected to false twist crimping or air processing. For example, a composite yarn composed of two or more types of false twist crimped yarns and having a torque of 30 T / m or less is also preferable.
かかる複合糸は例えば以下の方法により製造することができる。すなわち、糸条を第１ローラ、セット温度が９０〜２２０℃（より好ましくは１００〜１９０℃）の熱処理ヒータを経由して撚り掛け装置によって施撚することによりｏｎｅ ｈｅａｔｅｒ仮撚捲縮加工糸を得てもよいし、必要に応じてさらに第２ヒーター域に導入して弛緩熱処理することによりｓｅｃｏｎｄ ｈｅａｔｅｒ仮撚捲縮加工糸を得てもよい。仮撚加工時の延伸倍率は、０．８〜１．５の範囲が好ましく、仮撚数は、仮撚数（Ｔ／ｍ）＝（３２５００／（Ｄｔｅｘ）１／２）×αの式においてα＝０．５〜１．５が好ましく、通常は０．８〜１．２位とするのがよい。ただし、Ｄｔｅｘとは糸条の総繊度である。用いる撚り掛け装置としては、デイスク式あるいはベルト式の摩擦式撚り掛け装置が糸掛けしやすく、糸切れも少なくて好ましいが、ピン方式の撚り掛け装置であってもよい。また、施撚の方向により、仮撚捲縮加工糸が有するトルクをＳ方向かＺ方向か選択することができる。次いで、２種以上の仮撚捲縮加工糸を合糸することにより前記複合糸が得られる。 Such a composite yarn can be produced, for example, by the following method. That is, a one-heater false twisted crimped yarn is obtained by twisting the yarn with a twisting device via a first roller and a heat treatment heater having a set temperature of 90 to 220 ° C. (more preferably 100 to 190 ° C.). It may be obtained, or a second heater false twisted crimped yarn may be obtained by introducing it into the second heater zone and subjecting it to a relaxation heat treatment if necessary. The draw ratio during false twisting is preferably in the range of 0.8 to 1.5, and the false twist number is the formula of false twist number (T / m) = (32500 / (Dtex) 1/2) × α. α = 0.5 to 1.5 is preferable, and usually 0.8 to 1.2. However, Dtex is the total fineness of the yarn. As the twisting device to be used, a disk-type or belt-type friction-type twisting device is preferable because it is easy to thread and there is little yarn breakage, but a pin-type twisting device may also be used. Further, depending on the direction of twisting, the torque of the false twist crimped yarn can be selected from the S direction or the Z direction. Next, the composite yarn is obtained by combining two or more types of false twist crimped yarn.
かかる複合糸には、インターレース加工により交絡が付与されていることが好ましい。交絡（インターレース）の個数は、ソフトな風合いを損なわないために３０〜９０個／ｍの範囲内であることが好ましい。該個数が９０個／ｍよりも大きいとソフトな風合いが損なわれるおそれがある。逆に、該個数が３０個／ｍよりも小さいと複合糸の集束性が不十分となり、製編織性が損なわれるおそれがある。なお、交絡処理（インターレース加工）は通常のインターレースノズルを用いて処理したものでよい。
なお、ノントルク（０Ｔ／ｍ）とするには、Ｓ方向のトルクを有する仮撚捲縮加工糸とＺ方向の仮撚捲縮加工糸とを合糸する際、トルクの方向が異なること以外は同じトルクを有する２種の仮撚捲縮加工糸を使用するとよい。
It is preferable that the composite yarn is entangled by interlace processing. The number of entanglements (interlaces) is preferably in the range of 30 to 90 / m in order not to impair the soft texture. If the number is greater than 90 / m, the soft texture may be impaired. On the other hand, when the number is less than 30 / m, the converging property of the composite yarn becomes insufficient, and the knitting property may be impaired. In addition, the entanglement process (interlace process) may be performed using a normal interlace nozzle.
For non-torque (0 T / m), when the false twisted crimped yarn having the torque in the S direction and the false twisted crimped yarn in the Z direction are combined, the torque direction is different. Two types of false twist crimped yarns having the same torque may be used.
