Abstract
Description
本発明は、常圧下でカチオン染料に可染性である常圧カチオン可染ポリエステル糸を使用したスパンライク様2層構造糸及びそれよりなる布帛に関する。 The present invention relates to a spun-like two-layer structure yarn using a normal pressure cationic dyeable polyester yarn that is dyeable to a cationic dye under normal pressure, and a fabric comprising the same.
ポリエステル繊維は、機械的強度、耐薬品性、耐熱性などに優れ、衣料用途で広く用いられている。近年、市場ニーズが多様化してきており、かかるポリエステル繊維、特にポリエステル長繊維で、高級ウールのようなスパンライクな風合や嵩高性をポリエステル繊維に付与する方法として、例えば特公昭60−11130号公報、特開平8−13275号公報、特開2006−169697号公報等に示されるように、2種以上の伸度差を有するポリエステルフィラメントを組み合わせ低伸度糸が外層(鞘)糸、高伸度糸が芯糸を構成するスパンライク様仮撚2層構造糸により嵩高性を向上させることが提案されている。こうした方法により良好な嵩高性でスパンライクなポリエステル織物が得られている(特許文献1〜3参照)。 Polyester fibers are excellent in mechanical strength, chemical resistance, heat resistance and the like, and are widely used in clothing applications. In recent years, market needs have been diversified, and as a method of imparting a spun-like texture and bulkiness to a polyester fiber such as high-grade wool with such a polyester fiber, in particular, a polyester long fiber, for example, Japanese Patent Publication No. 60-11130 As shown in Japanese Patent Laid-Open No. 8-13275, Japanese Patent Laid-Open No. 2006-169697, etc., a low elongation yarn is formed by combining two or more types of polyester filaments having a difference in elongation, and an outer layer (sheath) yarn, a high elongation It has been proposed to improve bulkiness by using a spun-like false twisted two-layer structure yarn in which the warp yarn constitutes the core yarn. By such a method, a good bulky and spun-like polyester fabric is obtained (see Patent Documents 1 to 3).
しかしながら、ポリエステル繊維は、その化学的特性から分散染料、アゾイック染料でしか染色できないため、鮮明且つ深みのある色相が得られにくいという欠点があり、その解決策として、外層糸を構成するポリエステル糸にスルホイソフタル酸の金属塩を2〜3モル%共重合してカチオン可染性にする方法が提案されている。(特許文献4、5参照)
確かにカチオン染料で良好な染色性を有するものの、高温・高圧下でしか染色することができないという問題があった。
However, polyester fibers can only be dyed with disperse dyes and azoic dyes because of their chemical properties, and therefore have a drawback that it is difficult to obtain a clear and deep hue. A method has been proposed in which a metal salt of sulfoisophthalic acid is copolymerized in an amount of 2 to 3 mol% to make it cationically dyeable. (See Patent Documents 4 and 5)
Although it has a good dyeability with a cationic dye, there is a problem that it can be dyed only under high temperature and high pressure.
常圧、100℃付近の温度で十分にカチオン可染性にしようとすれば、スルホイソフタル酸の金属塩を多量に共重合されることが必要となり、その結果スルホネート基による増粘効果から、ポリエステルの重合度を高くすることができず、溶融紡糸にて得られるポリエステル繊維の強度が著しく低下し、仮撚2層構造糸の工程操業性が著しく悪化するという問題があった。 In order to make it sufficiently cationic dyeable at normal pressure and at a temperature of around 100 ° C., it is necessary to copolymerize a large amount of the metal salt of sulfoisophthalic acid. The degree of polymerization cannot be increased, the strength of the polyester fiber obtained by melt spinning is significantly reduced, and the process operability of the false twisted two-layer structure yarn is significantly deteriorated.
一方、このような問題に対して、イオン結合性分子間力の小さいカチオン可染モノマーを共重合する技術が開示されている(特許文献6,7参照)。イオン結合性分子間力の小さいカチオン可染モノマーとして、5−スルホイソフタル酸テトラブトキシホスホネートなどが例示されているが、これらのカチオン可染モノマー共重合ポリエステルは熱安定性が悪く、常圧カチオン可染化させるため、共重合量を増加させると重合反応途中で熱分解が進行し、高分子量化させることが困難であった。さらに溶融紡糸する際の熱履歴による分解が大きく、結果として得られる糸の強度が弱くなり、仮撚2層構造糸の工程操業性が著しく悪化するという問題があった。 On the other hand, a technique for copolymerizing a cationic dyeable monomer having a small ion-binding intermolecular force is disclosed for such problems (see Patent Documents 6 and 7). Examples of cationic dyeable monomers having a small ion-binding intermolecular force include 5-sulfoisophthalic acid tetrabutoxyphosphonate. These cationic dyeable monomer copolyesters have poor thermal stability and are capable of cationic cation. When the amount of copolymerization is increased for the purpose of dyeing, thermal decomposition proceeds in the middle of the polymerization reaction, making it difficult to increase the molecular weight. Furthermore, there is a problem that the decomposition due to the heat history during melt spinning is large, the resulting yarn has weak strength, and the process operability of the false twisted two-layer structure yarn is remarkably deteriorated.
更にスルホイソフタル酸の金属塩に分子量が2000以上のポリエチレングリコールを共重合する方法、アジピン酸、セバシン酸などの直鎖炭化水素のジカルボン酸を共重合する方法、あるいはジエチレングリコール、ネオペンチルグリコール、シクロヘキサンジメタノールのようなグリコール成分を共重合する方法等により常圧カチオン可染性を改善する方法が提案されている。(特許文献8、9参照)
しかしながら、これらいずれの方法でも得られたポリエステルを溶融紡糸して得られる常圧カチオン可染性ポリエステル繊維の強度は十分でなく、仮撚2層構造糸の工程操業性が著しく悪化する又布帛の引き裂き強度が低下するという問題があった。
Further, a method of copolymerizing polyethylene glycol having a molecular weight of 2000 or more with a metal salt of sulfoisophthalic acid, a method of copolymerizing a dicarboxylic acid of a linear hydrocarbon such as adipic acid or sebacic acid, or diethylene glycol, neopentyl glycol, cyclohexane di A method for improving the atmospheric pressure cationic dyeability by a method of copolymerizing a glycol component such as methanol has been proposed. (See Patent Documents 8 and 9)
However, the strength of the normal pressure cationic dyeable polyester fiber obtained by melt spinning the polyester obtained by any of these methods is not sufficient, and the process operability of the false twisted two-layer structure yarn is significantly deteriorated. There was a problem that the tear strength was reduced.
また、5−ナトリウムスルホイソフタル酸を共重合したポリエステルを鞘部に、95モル%以上がエチレンテレフタレートの繰返し単位からなるポリエステルを芯部に配した複合繊維が提案されている(特許文献10参照)。しかしながら、鞘部を構成する共重合ポリエステル中のスルホイソフタル酸成分の共重合量には、前述と同様の理由で限界があり、十分なカチオン染着性を得ることが困難であること、並びに複合繊維とすることで紡糸工程での加工コストが増加、または繊維断面形状などに制約が生じるなどの課題があった。
こうした現状に鑑み、ポリエステル糸からなる常圧カチオン可染性仮撚2層構造糸の開発が大いに望まれていた。
Further, a composite fiber has been proposed in which a polyester copolymerized with 5-sodium sulfoisophthalic acid is disposed in a sheath portion and a polyester having 95% by mole or more of ethylene terephthalate repeating units disposed in a core portion (see Patent Document 10). . However, the copolymerization amount of the sulfoisophthalic acid component in the copolymer polyester constituting the sheath part is limited for the same reason as described above, and it is difficult to obtain sufficient cationic dyeing properties. By using fibers, there have been problems such as an increase in processing cost in the spinning process or a restriction on the fiber cross-sectional shape.
In view of the current situation, development of a normal pressure cationic dyeable false twist two-layer structure yarn made of polyester yarn has been highly desired.
本発明は上記の課題を解決するものであり、常圧下でのカチオン染色が可能なスパンライクポリエステル2層構造糸を提供するものである。 The present invention solves the above-described problems and provides a spun-like polyester two-layer structured yarn capable of cationic dyeing under normal pressure.

(Description of component B)
The compound (B) represented by the chemical formula (1) is quaternary phosphonium salt or quaternary ammonium salt of 5-sulfoisophthalic acid or its lower alkyl ester. As the quaternary phosphonium salt, the quaternary ammonium salt is preferably a quaternary phosphonium salt or a quaternary ammonium salt substituted with an alkyl group, a benzyl group or a phenyl group, and particularly preferably a quaternary phosphonium salt. The four substituents may be the same or different. Specific examples of the compound represented by the chemical formula (1) include 5-sulfoisophthalic acid tetrabutylphosphonium salt, 5-sulfoisophthalic acid ethyltributylphosphonium salt, 5-sulfoisophthalic acid benzyltributylphosphonium salt, and 5-sulfoisophthalic acid. Acid phenyltributylphosphonium salt, 5-sulfoisophthalic acid tetraphenylphosphonium salt, 5-sulfoisophthalic acid butyltriphenylphosphonium salt, 5-sulfoisophthalic acid benzyltriphenylphosphonium salt, or dimethyl ester or diethyl ester of these isophthalic acid derivatives Preferably exemplified.
(数式1の説明)
本発明で使用される常圧カチオン可染性ポリエステルに共重合させる成分Aと成分Bの合計は酸成分を基準として、A+Bが3.0〜5.0モル%の範囲である必要がある。3.0モル%より少ないと、常圧下でのカチオン染色では十分な染着を得ることができない。一方、5.0モル%より多くなると、得られるポリエステル糸の強度が低下するため実用に適さない。さらに染料を過剰に消費するため、コスト面でも不利である。
(Explanation of Formula 1)
The total of component A and component B copolymerized with the normal pressure cationic dyeable polyester used in the present invention needs to be within a range of 3.0 to 5.0 mol% based on the acid component. If it is less than 3.0 mol%, sufficient dyeing cannot be obtained by cationic dyeing under normal pressure. On the other hand, if it exceeds 5.0 mol%, the strength of the resulting polyester yarn is lowered, which is not suitable for practical use. Further, since the dye is consumed excessively, it is disadvantageous in terms of cost.
(数式2の説明)
また、成分Aと成分Bの成分比は、B/(A+B)が0.2〜0.7の範囲にある必要がある。0.2以下、つまり成分Aの割合が多い状態では、スルホイソフタル酸金属塩による増粘効果により、得られるポリエステルの重合度を上げることが困難になる。一方、0.7以上、つまり成分Bの割合が多い状態では、反応が遅くなり、さらに成分Bの比率が多くなると分解が進むため重合度を上げることができない。さらに、成分Bの比率多くなると熱安定性が悪化し、溶融紡糸段階で再溶融した際の熱分解による分子量の低下が大きくなるため、得られるポリエステル糸のタフネスが低下し仮撚での毛羽や断糸が多発するために好ましくない。
(Explanation of Formula 2)
The component ratio between component A and component B must be such that B / (A + B) is in the range of 0.2 to 0.7. When the ratio is 0.2 or less, that is, in a state where the proportion of component A is large, it is difficult to increase the degree of polymerization of the resulting polyester due to the thickening effect of the metal salt of sulfoisophthalic acid. On the other hand, when the ratio is 0.7 or more, that is, the ratio of the component B is large, the reaction is slow, and when the ratio of the component B is further increased, the decomposition proceeds and the degree of polymerization cannot be increased. Further, when the ratio of component B increases, the thermal stability deteriorates, and the molecular weight decreases due to thermal decomposition when remelted in the melt spinning stage. Therefore, the toughness of the resulting polyester yarn decreases, and fuzz in false twisting This is not preferable because many yarn breaks occur.
(DEG量の説明)
本発明で使用される常圧カチオン可染性ポリエステルに含有されるジエチレングリコールは、0.3〜2.5重量%であることが好ましい。2.5重量%を超える場合は工程通過性が低下し、断糸が多発するとともに十分な強度が得られないため好ましくない。0.3%未満の場合は、ポリマーの生産能力を極めて小さくする必要があるため事実上不可能である。好ましくは0.5〜2.5重量%であり、さらに好ましくは1.0〜2.0重量%である。
(Description of DEG amount)
The diethylene glycol contained in the atmospheric pressure cationic dyeable polyester used in the present invention is preferably 0.3 to 2.5% by weight. When the amount exceeds 2.5% by weight, the process passability is lowered, the yarn is broken frequently, and a sufficient strength cannot be obtained. If it is less than 0.3%, it is practically impossible because the polymer production capacity needs to be extremely small. Preferably it is 0.5 to 2.5 weight%, More preferably, it is 1.0 to 2.0 weight%.
DEG量を上記の範囲に抑制するためには、DEG抑制剤として少々のアルカリ金属塩、アルカリ土類金属塩、水酸化テトラアルキルホスホニウム、水酸化テトラアルキルアンモニウム、トリアルキルアミンなどの少なくとも1種類を、使用するカチオン可染性モノマー(本発明の場合は化合物(A)及び(B))に対して、1〜20モル%程度を添加することが好ましい。 In order to suppress the amount of DEG within the above range, at least one kind of alkali metal salt, alkaline earth metal salt, tetraalkylphosphonium hydroxide, tetraalkylammonium hydroxide, trialkylamine, etc., is used as a DEG inhibitor. In addition, it is preferable to add about 1 to 20 mol% with respect to the cationic dyeable monomer to be used (in the case of the present invention, the compounds (A) and (B)).
(常圧カチオン可染性ポリエステルの製造)
本発明で使用される常圧カチオン可染性ポリエステルの製造は特に限定されず、通常知られているポリエステルの製造方法が用いられる。すなわち、テレフタル酸とエチレングリコールの直接重縮合反応させる、あるいはテレフタル酸ジメチルに代表されるテレフタル酸のエステル形成性誘導体とエチレングリコールとをエステル交換反応させて低重合体を製造する。次いでこの反応性生物を重縮合触媒の存在下で減圧加熱して所定の重合度になるまで重縮合反応させることにより製造される。スルホイソフタル酸を含有する芳香族ジカルボン酸および/またはそのエステル誘導体を共重合する方法についても通常知られている製造方法を用いる事ができる。
(Manufacture of atmospheric pressure cationic dyeable polyester)
The production of the normal pressure cationic dyeable polyester used in the present invention is not particularly limited, and a conventionally known polyester production method is used. That is, a low polymer is produced by a direct polycondensation reaction between terephthalic acid and ethylene glycol, or an ester exchange reaction between an ester-forming derivative of terephthalic acid typified by dimethyl terephthalate and ethylene glycol. Subsequently, this reactive organism is produced by heating under reduced pressure in the presence of a polycondensation catalyst to carry out a polycondensation reaction until a predetermined polymerization degree is reached. As a method for copolymerizing an aromatic dicarboxylic acid containing sulfoisophthalic acid and / or an ester derivative thereof, a generally known production method can be used.
(その他添加剤)
また、本発明で使用される常圧カチオン可染性ポリエステルは、必要に応じて少量の添加剤、例えば酸化防止剤、蛍光増白剤、帯電防止剤、抗菌剤、紫外線吸収剤、光安定剤、熱安定剤、遮光剤または艶消し剤などを含んでいても良い。特に酸化防止剤、艶消し剤などは特に好ましく添加される。
(Other additives)
Further, the atmospheric pressure cationic dyeable polyester used in the present invention may contain a small amount of additives such as antioxidants, fluorescent whitening agents, antistatic agents, antibacterial agents, ultraviolet absorbers, and light stabilizers as necessary. , A heat stabilizer, a light-shielding agent or a matting agent may be contained. In particular, antioxidants and matting agents are particularly preferably added.
(外層部糸の製糸方法)
上記により得られたポリエステルは公知の方法により製糸する。例えば、得られた常圧カチオン可染性ポリエステルを溶融状態で繊維状に押出し、それを500〜3500m/分の速度で溶融紡糸し、延伸、熱処理する方法、1000〜5000m/分の速度で溶融紡糸し、延伸する方法、5000m/分以上の高速で溶融紡糸し、用途によっては延伸工程を省略する方法などが好ましく挙げられる。
外層部糸の常圧カチオン可染性ポリエステル繊維の伸度は45%以上であることが好ましい。45%未満では2層構造糸の嵩高性が得られず好ましくない。
(Outer layer yarn production method)
The polyester obtained as described above is produced by a known method. For example, the obtained normal pressure cationic dyeable polyester is extruded into a fiber form in a molten state, melt-spun at a speed of 500 to 3500 m / min, drawn and heat treated, and melted at a speed of 1000 to 5000 m / min. A method of spinning and stretching is preferably exemplified by a method in which melt spinning is performed at a high speed of 5000 m / min or more, and a stretching process is omitted depending on applications.
The elongation of the normal pressure cationic dyeable polyester fiber of the outer layer yarn is preferably 45% or more. If it is less than 45%, the bulkiness of the two-layer structured yarn cannot be obtained, which is not preferable.
本発明の外層部糸の単繊維繊度は4dtex以下が好ましい。4dtexを超える場合には、混繊時に芯鞘構造とすることが難しい。一方、単繊維繊度の下限については特に制限はないが、実用的に繊維形成可能で、かつ布帛の耐摩耗性を著しく損なわないという観点から、0.1dtex以上が好ましい。
本発明の外層部糸の常圧カチオン可染性ポリエステル繊維の断面形状は、用途等に応じて任意の形状とすることができ、例えば円形の他、三角、偏平、星型、V型等の異形断面またはそれらの中空断面が例示できる。
The single fiber fineness of the outer layer yarn of the present invention is preferably 4 dtex or less. When it exceeds 4 dtex, it is difficult to obtain a core-sheath structure at the time of fiber mixing. On the other hand, the lower limit of the single fiber fineness is not particularly limited, but is preferably 0.1 dtex or more from the viewpoint that fibers can be formed practically and the wear resistance of the fabric is not significantly impaired.
The cross-sectional shape of the normal pressure cationic dyeable polyester fiber of the outer layer portion yarn of the present invention can be any shape depending on the application, for example, in addition to a circle, such as a triangle, a flat shape, a star shape, a V shape, etc. An irregular cross section or a hollow cross section thereof can be exemplified.
(芯糸)
次に、本発明の2層構造糸の芯糸としては、ポリエステル繊維が好ましく、伸度25%以下であることが好ましい。25%を超える場合2構造糸の嵩高性が取れなくなり好ましくない。
(Core yarn)
Next, as a core yarn of the two-layer structure yarn of the present invention, a polyester fiber is preferable, and an elongation of 25% or less is preferable. If it exceeds 25%, the bulkiness of the two-structure yarn cannot be obtained, which is not preferable.
(2層構造糸の製造方法)
嵩高性の良好な2層構造糸とするためには芯糸と外層部糸とは伸度の差が20%以上あることが好ましい。伸度の差が20%未満の場合、嵩高性が低下し好ましくない。
2層構造糸とするためには上述の芯糸および外層部糸を引きそろえて空気交絡処理に付されその後非接触ヒーターで延伸仮撚加工する工程を経ることにより得られる。この場合、両者の使用割合は芯糸:外層部糸=25:75〜75:25(重量)とすればよい。空気交絡としては、インターレース、タスラン加工の何れであってもよい。 具体的には図1の工程を示すことができる。
ここで、交絡付与後にオーバーフィードをかけながらヒーターで熱処理すると、芯糸は収縮し、外層部糸は殆ど収縮しないかあるいは自己伸張し、芯糸と外層部糸との間に糸足差が生じ、これが布帛とした時の膨らみ、スパンライク性に繋がる。
(Method for producing two-layer structured yarn)
In order to obtain a two-layer structure yarn having good bulkiness, the difference in elongation between the core yarn and the outer layer yarn is preferably 20% or more. If the difference in elongation is less than 20%, the bulkiness is lowered, which is not preferable.
In order to obtain a two-layer structure yarn, the above-described core yarn and outer layer portion yarn are aligned and subjected to an air entanglement treatment, and then subjected to a drawing false twisting process with a non-contact heater. In this case, the use ratio of both may be core yarn: outer layer yarn = 25: 75 to 75:25 (weight). The air entanglement may be either interlaced or Taslan processing. Specifically, the process of FIG. 1 can be shown.
Here, if heat treatment is performed with a heater while applying overfeeding after confounding, the core yarn shrinks and the outer layer yarn hardly shrinks or self-extends, resulting in a difference in yarn foot between the core yarn and the outer layer yarn. This leads to swelling and spun-like properties when used as a fabric.
