- ester derivatives such as dimethyl esters.
- These ester derivatives such as methyl and dimethyl ester are preferably used in that the whiteness of the polymer and the polymerization rate are excellent.
- the polyester fiber preferably contains a metal sulfonate group-containing isophthalic acid component such as 5-sodium sulfoisophthalic acid or 5-potassium sulfoisophthalic acid, and dimethyl 5-sodium sulfoisophthalate is particularly preferred.
- ester-forming sulfonate compound is particularly preferable in the case of ordinary polyester fiber, the terminal is hydrolyzed by alkali treatment, so that the oligomer is hardly formed, whereas the ester-forming sulfonate compound is used.
- the alkali treatment preferentially attacks the S element portion due to the alkali treatment and the cleavage in the middle of the molecular chain occurs, so that the oligomer having a carboxyl group at the terminal increases.
- the polyester fiber according to the present embodiment can be a polyester fiber containing a non-ester-forming sulfonate compound.

If the content of S element is less than 0.005 wt%, the durability effect of water absorption after alkali treatment is small, and if the S fiber is contained in the polyester fiber in an amount of 1 wt% or more, the strength of the fiber is lowered and spinning is difficult. It becomes.

- the weight loss rate can be calculated from the weight of the polyester yarn before and after the alkali treatment. In the case of a polyester fiber containing an ester-forming sulfonate compound in an amount of 0.5 to 5 mol%, the rate of alkali weight loss is faster than that of a normal polyester fiber.
- the weight loss rate is less than 0.6%, the effect of forming the linear oligomer component of the terminal carboxylic acid by the alkali treatment is small and the durability of water absorption is poor. If the weight loss rate is larger than 9%, the alkali weight loss is excessively advanced, resulting in poor water absorption durability. It is presumed that the linear oligomer of the terminal carboxylic acid on the fiber surface once formed falls off due to excessive weight loss. Also, many large and deep pits are generated on the fiber surface, and the fiber strength is lowered. In order to reduce the weight loss ratio to 0.6 to 9%, for example, an alkali treatment method in which sodium hydroxide is treated at a concentration of 1 g / L to 20 g / L at 90 to 100 ° C.

- the temperature raising speed during the alkali treatment is important, and it is preferable to raise the temperature slowly at a rate of 1 to 2 ° C./min. This is presumed to be because oligomer formation is promoted by slowly raising the temperature.
- the alkali treatment is neutralized with an acid and washed with water.
- a cyclic oligomer that inhibits water absorption can be removed by a specific oligomer removal treatment.
- conditions for washing with water for example, it is preferable to carry out for 10 to 30 minutes twice or more.
- “Two or more times” means that water is drained once and the water is replaced two or more times. More preferably, hot water at 40 ° C. to 60 ° C. is used once or more.
- volatile acetic acid etc. are used suitably for the acid at the time of neutralization.
- the alkaline solution may be collected and then neutralized to enhance washing with water.
- alkali treatment is carried out by using a cheese dyeing machine so that the polyester fiber containing 0.005 to 1 wt% of S element has a weight loss rate of 0.6 to 9% in the state of yarn. And a method of forming a fabric using the polyester fiber as a part is preferably used. Even in this case, the weight loss rate is preferably 0.6 to 9%, more preferably 1 to 8%, and still more preferably 1.5 to 7%. In addition, it is preferable to perform sufficient washing as described above.

- the average number of grooves is preferably 1 or less, more preferably 0.1 or less.
- the length means the maximum length of one pit. It is estimated that very small pits are formed on the surface of the polyester fiber of the present embodiment, thereby contributing to durable water absorption.
- a pit having a length of 0.5 ⁇ m or less is not preferable because the water absorption effect is poor, and the presence of a streak-like groove having a length exceeding 5 ⁇ m means that the alkali treatment has proceeded excessively and the decomposition has proceeded excessively. Also, the case where the number of pits having a length of 0.5 to 5 ⁇ m exceeds 30 is not preferable because it means that the alkali treatment has proceeded excessively. In the present embodiment, even if alkali weight reduction is performed, there is no generation of streak-like grooves or communication holes having a length exceeding 5 ⁇ m, so the rate of decrease in strength is small.

Description
例えば、以下の特許文献1では、ポリエステル繊維を吸水剤で処理した後、吸水剤をハイドロゲルで被覆することにより、吸水性等を付与している。この方法では、吸水剤が加工で付与されており、ハイドロゲルによる被覆を施しても吸水性の劣化は避けられず、洗濯を繰り返すと性能が低下してしまい、工業洗濯のような高温の洗濯ではさらに性能が低下する可能性がある。さらにハイドロゲルの被覆により、繊維の柔らかさを損なう恐れもある。
すなわち、本発明は以下の通りのものである。

本実施形態の布帛を構成するポリエステル繊維は、表面に末端カルボン酸の直鎖オリゴマー成分が存在することを特徴としている。表面に末端カルボン酸の直鎖オリゴマー成分が存在することで吸水性の繰り返し洗濯耐久性が発現するものである。ここで、末端カルボン酸の直鎖オリゴマー成分は、例えば、以下の式(1):
該オリゴマー成分は、以下に記す、2種の分析手法の組み合わせによって定性、定量することによって存在が確認できる。
かかる末端カルボン酸の直鎖オリゴマー成分のうち、比較的低分子のオリゴマー成分はTHFに溶解し、LC/MS(液体クロマトグラフィー質量分析法)で分析することができる。その代表的成分をn=4とすると、繊維表面に存在するn=4のオリゴマー成分は、以下の方法で測定することができる。
20mL容量のガラスサンプル瓶(AS ONE ラボランパック スクリュー管瓶 9-852-07 NO.5)中に、試料として布帛から取り出したポリエステル糸100mgを入れ、THF3mlを添加する。ヤマト マグミキサー 形式M-41を用いて回転数約800回/分で6時間撹拌した後、4日間静置し、THF溶液のLC/MSを行うことで試料から抽出した成分の分析を行う。THF溶液のサンプリングに際し、固形分が入らないようにして0.495mlの溶液を採取し、内部標準として、Methyl Benzoate 1mg/ml溶液を0.005ml添加し試料とした。LC/MS分析の条件は以下の表1に示すとおりである。
UVクロマトグラムにおいて、前記オリゴマー由来のピークが明確でない場合には、質量数785のマスクロマトグラム(縦軸:特定質量数の検出強度、横軸:保持時間)を表示させ、UVスペクトル例から推定される保持時間(図1では約4.5min.)付近に該質量数の検出強度ピーク(ピークzとする)が存在するか否かで、該オリゴマーが存在するか否かを判断できる。
このように末端カルボン酸の直鎖オリゴマーは、吸水性に寄与するが、例えば、以下の式(2):
具体的には図1のUVクロマトグラム(240nm)のチャートの例において、ピークbがn=3の環状オリゴマー成分のピークである。このピークが該環状オリゴマー成分(分子量576.18)由来であることは、そのピークのESI-質量スペクトル(エレクトロスプレーイオン化、正イオン質量スペクトル)において、質量数(m/z)594のイオン([M+NH4]+)が検出されることにより確認できる。UVクロマトグラムにおいて、前記オリゴマー由来のピークが明確でない場合には、n=4末端カルボン酸直鎖オリゴマーと同様に、質量数594のマスクロマトグラムを表示させ、UVスペクトル例から推定される保持時間(図1では約5.3min.)付近に該質量数の検出強度ピーク(ピークwとする)が存在するか否かで、該オリゴマーが存在するか否かを判断できる。
該オリゴマー成分の存在量は、UVクロマトグラムのピーク面積値で測定でき、内部標準として添加したMethyl BenzoateのUVクロマトグラムのピーク(ピークsとする)のピーク面積値との比率から濃度換算することができる。
THFでオリゴマーを抽出した後の試料を風乾したのち、2mgを採取し、20mL容量のガラスサンプル瓶に入れ、1mlのHFIP(ヘキサフロロイソプロパノール)を加え、試料を溶解させる。また、以下に示すマトリックス溶液も調整する。試料溶液20μLを取り、マトリックス溶液20μLを添加する。溶液を採取するガラス毛細管で撹拌、混合後、すぐに析出分が確認される。上層にある析出分ではなく、下層溶液を採取し、下記条件でMALDI―TOF/MS測定を行う。測定に際して、マトリックスの強度が50mV/Profiles以上2000mV/Profiles未満のレーザー強度で測定を行う。

本実施形態においては、式(1)のn=4~10の末端カルボン酸の直鎖オリゴマー成分を有していることが吸水性の耐久性に非常に効果的である。n=4~10の末端カルボン酸の直鎖オリゴマー成分の定量は以下の方法で行う。
n=4~10の末端カルボン酸の直鎖オリゴマーのピークは、MALDI-TOF/MSの正イオンスペクトルにおいてNa付加体として検出される。該オリゴマー成分量は、該オリゴマーNa付加体のピーク強度をマトリックスピーク強度で規格化した値で評価できる。すなわち、該オリゴマーNa付加体ピーク高さを、マトリックスであるCHCAのNa付加体ピーク(m/z=212)高さで除した値を成分量の指標とし、n=4~n=10のそれぞれのオリゴマーNa付加体ピーク高さをCHCAのNa付加体ピークの高さで除し、それらの総和で評価する。この値が0.07以上であるのが好ましく、0.10以上がさらに好ましい。総和値が0.5を超えると分解が進みすぎているため、好ましくない。
ポリエステル繊維に0.5~5モル%含有させるエステル形成性スルホン酸塩化合物の例としては、5-ナトリウムスルホイソフタル酸、5-カリウムスルホイソフタル酸、4-ナトリウムスルホ-2,6-ナフタレンジカルボン酸、2-ナトリウムスルホ-4-ヒドロキシ安息香酸、3,5-ジカルボン酸ベンゼンスルホン酸テトラメチルホスホニウム塩、3,5-ジカルボン酸ベンゼンスルホン酸テトラブチルホスホニウム塩、3,5-ジカルボン酸ベンゼンスルホン酸トリブチルメチルホスホニウム塩、2,6-ジカルボン酸ナフタレン-4-スルホン酸テトラブチルホスホニウム塩、2,6-ジカルボン酸ナフタレン-4-スルホン酸テトラメチルホスホニウム塩、3,5-ジカルボン酸ベンゼンスルホン酸アンモニウム塩等又はこれらのメチル、ジメチルエステル等のエステル誘導体が挙げられる。これらのメチル、ジメチルエステル等のエステル誘導体はポリマーの白度、重合速度が優れる点で好ましく用いられる。ポリエステル繊維に、5-ナトリウムスルホイソフタル酸、5-カリウムスルホイソフタル酸等金属スルホネート基含有イソフタル酸成分を含有させることが好ましく、中でも5-ナトリウムスルホイソフタル酸ジメチルは特に好ましい。
吸水性を発現させるために、アルカリ処理の条件としては該ポリエステル繊維の減量率を好ましくは0.6~9%、より好ましくは1~8%、さらに好ましくは1.5~7%にすることが好ましい。減量率はアルカリ処理前後のポリエステル糸の重量から算出できる。エステル形成性スルホン酸塩化合物を0.5~5モル%含有するポリエステル繊維の場合は通常のポリエステル繊維に比べアルカリ減量の速度が速いため、アルカリを低濃度に調整し、処理することが好ましい。
通常、アルカリ処理の後には酸で中和し、水洗するが、本発明においては特定のオリゴマー除去処理を行うことが非常に重要である。特定のオリゴマー除去処理により、吸水性を阻害する環状オリゴマーを除去することができる。オリゴマー除去の方法はいくつか挙げられる。たとえばオリゴマー除去剤を使用する方法や水洗を強化する方法などである。このうち、アルカリ処理後の水洗を強化する方法が、吸水性を阻害する環状オリゴマーを除去し、吸水性に寄与するn=4~10の末端カルボン酸の直鎖オリゴマーが除去されにくいことから特に好ましい。水洗の条件としては、例えば、10~30分間を2回以上行うことが好ましい。2回以上とは一度水を排水し、水を入れ替えることを2回以上行うことを意味する。40℃~60℃の温水を1回以上使用することがさらに好ましい。尚、中和時の酸には揮発性の酢酸等が好適に用いられる。設備によってはアルカリ溶液を回収し、その後に中和し、水洗を強化してもよい。
アルカリ処理の他の方法としてはS元素を0.005~1wt%含有するポリエステル繊維を糸の状態で0.6~9%の減量率になるようにチーズ染色機を用いる方法などでアルカリ処理を施し、該ポリエステル繊維を一部に用いて布帛を形成する方法が好適に用いられる。この場合においても減量率は、好ましくは0.6~9%、より好ましくは1~8%、さらに好ましくは1.5~7%にすることが好ましい。また、上述の十分な水洗を行うことが好ましい。
経編地の場合、特定のオリゴマーが付着されたポリエステル繊維のループが繋がるように配置するのが好ましい。
特に、糸にフッ素系処理剤を付着させるなど撥水加工を施した撥水糸との組合せにより、布帛内の水分保持の配置や移動を自在にコントロールすることができる。例えば、肌面に撥水糸を配置し、かつ少量の特定のオリゴマーが付着されたポリエステル繊維を配置し、該ポリエステル繊維を表面側に繋げば、該ポリエステル繊維から水を吸い上げ表側に水を移行することが可能になり、肌面には汗が残らず、汗処理性に優れた布帛を設計することが可能になる。
本実施形態に用いる繊維には、二酸化チタン等の艶消剤、リン酸等の安定剤、ヒドロキシベンゾフェノン誘導体等の紫外線吸収剤、タルク等の結晶化核剤、フュームドシリカ等の易滑剤、ヒンダードフェノール誘導体等の抗酸化剤、難燃剤、制電剤、顔料、蛍光増白剤、赤外線吸収剤、消泡剤等が含有されていてもよい。
捲縮糸の上端を固定し、下端に1.77×10-3cN/dtexの荷重をかけ、30秒後の長さ(A)を測定する。次いで、1.77×10-3cN/dtexの荷重を取り外し、0.088cN/dtexの荷重をかけ、30秒後の長さ(B)を測定し、下記式(3):
捲縮伸長率(%)={(B-A)/A}×100 (3)
により捲縮伸長率を求める。
織物の場合の織組織としては平織組織、綾織組織、朱子織組織、及びそれらから誘導された各種変化組織を適用することができる。肌側に耐久的な吸水性を付与するためには2重織り組織で肌側の25%以上に特定のオリゴマーが付着されたポリエステル繊維を配置するのが好ましい。
編物の場合は丸編、経編のいずれでもよく、編機としては、緯編機やダブル丸編機、トリコット編機、ラッセル編機等を使用できる。使用する編機の編ゲージとしては10~60GGが好ましい。編組織も特に限定されない。肌側に耐久的な吸水性を付与するためには表裏面に異なる糸を配置できる組織で肌側の25%以上に特定のオリゴマーが付着されたポリエステル繊維を配置するのが好ましい。
また、本発明の布帛には吸水加工を施してもよい。
