Description
本発明は水溶性の３級アミンオキシドにおけるセルロース水溶液より作られたセルロース成型体，特に，繊維及びこれら繊維を含む繊維品の処理プロセスに関する。このプロセスにおいて成型体は，成型体に優れた特性を与えるために繊維助剤と接触している。 The present invention relates to a cellulose molded body made from an aqueous cellulose solution in a water-soluble tertiary amine oxide, and more particularly to a process for treating fibers and textiles containing these fibers. In this process, the molded body is in contact with a fiber aid to give the molded body excellent properties.
本発明において，“成型体”には特にスポンジも含まれるものとする。 In the present invention, the “molded body” particularly includes a sponge.
ビスコース法に代わるものとして，近年多数のプロセスが挙げられてきた。これらプロセスにおいては，繊維は誘導体を形成することなく，有機溶剤，有機溶剤と無機塩類とが化合したもの，あるいは水溶性の食塩水に溶解する。このような溶液から作られたセルロース繊維は，“溶剤紡糸セルロース繊維”と呼ばれ，ＢＩＳＦＡ（国際化学繊維標準化協会）において一般名リヨセルとされている。ＢＩＳＦＡは，紡糸プロセスにより有機溶剤から得られたセルロース繊維をリヨセルとして定義している。ＢＩＳＦＡは「有機溶剤」を，有機化合物と水の混合物と理解している。「溶剤紡糸」は，誘導体化することのない溶解および紡糸とされている。 Many processes have been mentioned in recent years as alternatives to the viscose method. In these processes, the fiber dissolves in an organic solvent, a combination of an organic solvent and an inorganic salt, or water-soluble saline without forming a derivative. Cellulose fibers made from such a solution are called “solvent-spun cellulose fibers” and are generally named Lyocell in BISFA (International Chemical Fiber Standards Association). BISFA defines a cellulose fiber obtained from an organic solvent by a spinning process as lyocell. BISFA understands an “organic solvent” as a mixture of an organic compound and water. “Solvent spinning” is considered to be dissolution and spinning without derivatization.
しかしこれまでは，工業規模で実現された溶剤紡糸セルロース繊維の製造プロセスはたった一つだけであった。このプロセスにおいては，第３級アミンオキシド，特にＮ−メチルモルホリン−Ｎ酸化物（ＮＭＭＯ）を，溶剤として用いる。このようなプロセスは例えば，米国特許４，２４６，２２１号公報に記載されており，高い引っ張り強さ，高い湿潤弾性率，および高い引っ掛け強さにより区別される繊維が提供される。 Until now, however, only one process for producing solvent-spun cellulose fibers has been realized on an industrial scale. In this process, tertiary amine oxides, particularly N-methylmorpholine-N oxide (NMMO), are used as solvents. Such a process is described, for example, in U.S. Pat. No. 4,246,221, which provides fibers distinguished by high tensile strength, high wet modulus, and high hook strength.
特許文献ＷＯ９９／１９５５５では，溶剤紡糸繊維の処理プロセスが記載されている。このプロセスでは，繊維は２，４−ジクロロ−６−ヒドロキシ−１．３．５−トリアジンあるいはその塩とそれぞれ接触している。このようにして作られた繊維は，繊維攣縮に対しより強い耐性を持つことを特徴とする。 Patent document WO 99/19555 describes a process for treating solvent-spun fibers. In this process, the fibers are in contact with 2,4-dichloro-6-hydroxy-1.3.5-triazine or a salt thereof, respectively. The fibers made in this way are characterized by greater resistance to fiber spasm.
米国特許５，７２８，８２３号公報では，シクロデキストリン誘導体，特に，２−クロロ−４−ヒドロキシ−１．３．５−トリアジニル−シクロデキストリンのナトリウム塩が知られている。この公報にはさらに，シクロデキストリンが結合する薄膜，膜，繊維あるいは皮革についても記載されている。シクロデキストリン誘導体により処理される繊維は，例えば，不快なにおいを吸収するのに適している。 US Pat. No. 5,728,823 discloses cyclodextrin derivatives, in particular the sodium salt of 2-chloro-4-hydroxy-1.3.5-triazinyl-cyclodextrin. This publication further describes thin films, membranes, fibers or leather to which cyclodextrin is bound. Fibers treated with cyclodextrin derivatives are suitable for absorbing unpleasant odors, for example.
特許文献ＷＯ０１／４８０２５では，架橋剤により多糖類と共有結合したシクロデキストリンについて記述されている。 Patent document WO 01/48025 describes a cyclodextrin covalently bonded to a polysaccharide by means of a crosslinking agent.
水溶性の３級アミンオキシドにおけるセルロース水溶液より作られたセルロース成型体は，シクロデキストリン及び／またはシクロデキストリン誘導体を含む繊維助剤により処理されても良く，これにより優れた特性を有する製品を作り出すことが分かっている。 Cellulose moldings made from aqueous cellulose solutions in water-soluble tertiary amine oxides may be treated with fiber aids containing cyclodextrins and / or cyclodextrin derivatives, thereby creating products with superior properties I know.
成型体は，決して乾いていない状態の繊維であることが好ましい。繊維は，生産工場で継続運転された後の処理段階において，決して乾いていない状態で処理されても良い。 The molded body is preferably a fiber that is never dried. The fibers may be processed in a never-dry state in the processing stage after being continuously operated in the production plant.
シクロデキストリンは，長時間にわたり放出可能な物質を含んでも良いことが知られている。本発明によるプロセスでは，シクロデキストリンあるいはシクロデキストリン誘導体それぞれを同時及び／または連続して用いた連続した製造プロセスの過程で，こういった物質により処理された繊維を入れることができる。 It is known that cyclodextrins may contain substances that can be released over a long period of time. In the process according to the invention, fibers treated with these substances can be introduced in the course of a continuous production process using cyclodextrin or cyclodextrin derivatives simultaneously and / or successively.
繊維助剤を用いた処理は，アルカリ環境の下でなされることが好ましい。 The treatment using the fiber aid is preferably performed in an alkaline environment.
また，繊維助剤はさらに，架橋剤を含むことが好ましく，特に，２，４−ジクロロ−６−ヒドロキシ−１．３．５−トリアジンあるいはその塩はそれぞれ，架橋剤として用いられることが好ましい。 Further, the fiber auxiliary further preferably contains a cross-linking agent, and in particular, 2,4-dichloro-6-hydroxy-1.3.5-triazine or a salt thereof is preferably used as the cross-linking agent.
米国特許５，７２８，８２３号公報による最新技術では，まず，シクロデキストリン誘導体，例えば，２−クロロ−４−ヒドロキシ−１．３．５−トリアジニル−シクロデキストリンのナトリウム塩は，続けて前記誘導体を処理物質に加えるため多大な労力の下製造されなくてはならない。 In the state of the art according to U.S. Pat. No. 5,728,823, first a cyclodextrin derivative, for example the sodium salt of 2-chloro-4-hydroxy-1.3.5-triazinyl-cyclodextrin, It must be manufactured with great effort to add to the treated material.
シクロデキストリン及び架橋剤，特に２，４−ジクロロ−６−ヒドロキシ−１．３．５−トリアジンは，最初にこれら２つの物質の化合物を調製しなくても，処理対象の繊維に対し加えられることが示されている。これにより良好な結果が得られる。 Cyclodextrins and crosslinkers, especially 2,4-dichloro-6-hydroxy-1.3.5-triazine, should be added to the fibers to be treated without first preparing compounds of these two materials. It is shown. This gives good results.
本発明によるプロセスのさらなる実施形態では，繊維助剤は２−クロロ−４−ヒドロキシ−１．３．５−トリアジニル−シクロデキストリン（ＭＣＴ−ＣＤ）あるいはその塩をそれぞれ含む。 In a further embodiment of the process according to the invention, the fiber aid comprises 2-chloro-4-hydroxy-1.3.5-triazinyl-cyclodextrin (MCT-CD) or a salt thereof, respectively.
本発明はまた，本発明に記載のプロセスにより得られる溶剤紡糸セルロース繊維，及びこれら繊維を含む繊維品に関する。 The present invention also relates to solvent-spun cellulose fibers obtained by the process described in the present invention, and textiles containing these fibers.
（実施例１）
特許文献ＷＯ９３／１９２３０記載のプロセスにより製造された，力価１．３ｄｔｅｘを有する溶剤紡糸繊維が，決して乾いていない状態で以下のように処理された。
(Example 1)
A solvent-spun fiber having a titer of 1.3 dtex produced by the process described in Patent Document WO 93/19230 was treated as follows without being dried.
繊維を液比１：１０で，２，４−ジクロロ−６−ヒドロキシ−１．３．５−トリアジンのナトリウム塩２０ｇ／ｌ，ＮａＯＨ１６ｇ／ｌ及びシクロデキストリン（ＣＡＶＡＭＡＸ Ｗ７，Ｍｅｓｓｒｓ． Ｗａｃｋｅｒ−Ｃｈｅｍｉｅ製）１００ｇ／ｌとを含む溶液に，室温で５分間含浸した。続いて，繊維を圧搾機で含水率１００％〜１１０％となるように絞り，飽和蒸気（１００％）で熱処理した（温度１００℃，５分間）。そしてその繊維をすすいで乾かした。 The fiber was in a liquid ratio of 1:10, 2,4-dichloro-6-hydroxy-1.3.5-triazine sodium salt 20 g / l, NaOH 16 g / l and cyclodextrin (CAVAMAX W7, Messrs. Wacker-Chemie). A solution containing 100 g / l was impregnated at room temperature for 5 minutes. Subsequently, the fiber was squeezed to a moisture content of 100% to 110% with a press and heat treated with saturated steam (100%) (temperature 100 ° C., 5 minutes). The fiber was rinsed and dried.
製造された繊維における活性シクロデキストリンの含有量は，フェノールフタレイン溶液（５５２ｎｍ）による脱色によって，光分析を用いて求められた結果，２．３３重量％であった。 The content of active cyclodextrin in the produced fiber was 2.33% by weight as a result of being obtained by decolorization with a phenolphthalein solution (552 nm) and using optical analysis.
繊維攣縮の程度は，個々の繊維の耐湿潤摩耗性（特許文献ＷＯ９９／１９５５５に従ったテスト方法）により決定された。このテスト方法によると，本発明により処理されたサンプルは平均２１０回転の値を呈することが分かる。これに比べ，処理されていない繊維はたったの４０〜６０回転の湿潤摩擦値を呈した。 The degree of fiber spasm was determined by the wet abrasion resistance of each individual fiber (test method according to patent document WO 99/19555). According to this test method, it can be seen that the samples processed according to the invention exhibit an average value of 210 revolutions. In comparison, untreated fibers exhibited a wet friction value of only 40-60 revolutions.
（実施例２）
２，４−ジクロロ−６−ヒドロキシ−１．３．５−トリアジンのナトリウム塩２０ｇ／ｌ，ＮａＯＨ１６ｇ／ｌ，ソーダ３０ｇ／ｌ及びシクロデキストリン（ＣＡＶＡＭＡＸ Ｗ７，Ｍｅｓｓｒｓ． Ｗａｃｋｅｒ−Ｃｈｅｍｉｅ製）５０ｇ／ｌとを含む処理溶液を用い，実施例１と同じ工程を経た。
(Example 2)
2,4-dichloro-6-hydroxy-1.3.5-triazine sodium salt 20 g / l, NaOH 16 g / l, soda 30 g / l and cyclodextrin (CAVAMAX W7, Messrs. Wacker-Chemie) 50 g / l The same process as in Example 1 was performed using a treatment solution containing
こうして得られた活性シクロデキストリンの含有量は，１．６５重量％であり，湿潤摩耗値は４７０回転であった。 The content of active cyclodextrin thus obtained was 1.65% by weight, and the wet wear value was 470 revolutions.
（実施例３）
ソーダ３０ｇ／ｌ及び２−クロロ−４−ヒドロキシ−１．３．５−トリアジニル−シクロデキストリン（ＭＣＴ−ＣＤ；ＣＡＶＡＳＯＬ Ｗ７ ＭＣＴ，Ｍｅｓｓｒｓ． Ｗａｃｋｅｒ−Ｃｈｅｍｉｅ製）１００ｇ／ｌとを含む処理溶液を用い，実施例１と同じ工程を経た。
(Example 3)
A treatment solution containing 30 g / l of soda and 100 g / l of 2-chloro-4-hydroxy-1.3.5-triazinyl-cyclodextrin (MCT-CD; CAVASOL W7 MCT, manufactured by Messrs. Wacker-Chemie), The same process as in Example 1 was performed.
こうして得られた活性ＭＣＴ−ＣＤの含有量は，１．８９重量％であった。 The content of active MCT-CD thus obtained was 1.89% by weight.
