Description
本発明は、ポリエステル系繊維構造物の加工剤、およびそれを用いた、耐加水分解性に優れるポリエステル系繊維構造物の製造方法に関するものである。 TECHNICAL FIELD The present invention relates to a processing agent for a polyester fiber structure, and a method for producing a polyester fiber structure having excellent hydrolysis resistance using the same.
近年は環境意識の高まりから、プラスチック廃棄物が問題となり、酵素や微生物による分解が期待される生分解性プラスチックが注目されている。また、地球温暖化の観点から、二酸化炭素の大気中への排気を抑制することが重要になっており、カーボンニュートラルという概念で表されるように、天然資源から作られる材料の使用が推奨される様になってきている。上記の問題から、特に非石油原料のポリ乳酸が脚光を浴びているが、ポリ乳酸は室温や高温の水中における加水分解性が非常に高く、さらには空気中の水分によっても分解されるという性質を持っている。これはポリ乳酸繊維だけの問題ではなく、ポリエステル系繊維に共通の問題であり、末端カルボキシル基から放出されるプロトンがエステルの加水分解の自己触媒として働くために加水分解が促進される。このため、熱水の存在下、高温、高湿度条件化で分解による強度低下が著しく、使用が制限されてきた。 In recent years, due to increasing environmental awareness, plastic waste has become a problem, and biodegradable plastics that are expected to be decomposed by enzymes and microorganisms have attracted attention. In addition, from the viewpoint of global warming, it is important to suppress the emission of carbon dioxide into the atmosphere, and the use of materials made from natural resources is recommended as represented by the concept of carbon neutral. It is becoming like this. Due to the above problems, polylactic acid, which is a non-petroleum raw material, is in the spotlight, but polylactic acid has a very high hydrolyzability in room temperature and high temperature water, and is also decomposed by moisture in the air. have. This is not only a problem with polylactic acid fibers but also a problem common to polyester fibers, and protons released from terminal carboxyl groups act as autocatalysts for ester hydrolysis, so that hydrolysis is accelerated. For this reason, in the presence of hot water, the strength is significantly reduced due to decomposition under high temperature and high humidity conditions, and its use has been limited.
これを解決する方法として、末端封鎖加工剤を添加することより末端カルボキシル基濃度を低下させる方法が特許文献1や特許文献2で開示されている。しかしながら、これらの方法は紡糸前にポリマーチップに混練・添加するため、紡糸時の高温により、末端封鎖加工剤が蒸発や分解による発煙を起こし、悪臭や有毒なガスを発生するという問題点があった。また、このために末端封鎖加工剤を過剰に添加しなければならないという問題もある。さらに紡糸性が悪化し生産性も低下する恐れもある。 As a method for solving this, Patent Document 1 and Patent Document 2 disclose a method of reducing the terminal carboxyl group concentration by adding a terminal blocking agent. However, since these methods are kneaded and added to the polymer chip before spinning, there is a problem in that the end-capping agent causes fuming due to evaporation or decomposition due to high temperature at the time of spinning, generating bad odor or toxic gas. It was. For this reason, there is also a problem that the end-capping agent must be added excessively. Further, the spinnability is deteriorated and the productivity may be lowered.
別の解決する方法としては、末端封鎖加工剤を溶媒を用いて溶解あるいは乳化剤にてエマルジョン化したものを被処理物に直接接触させて、被処理物の表面に末端封鎖を付加する方法が特許文献3で開示されている。しかしながら、この方法は処理物表面近傍にのみ末端封鎖加工剤が存在するため、末端封鎖加工剤の付与量が十分なものではなく、長期間の湿熱に対する耐加水分解性は不十分なものである。 As another method for solving the problem, there is a method in which an end-capping agent dissolved in a solvent or emulsified with an emulsifier is brought into direct contact with the object to be treated and a terminal block is added to the surface of the object to be treated. It is disclosed in Document 3. However, in this method, since the end-capping agent exists only in the vicinity of the treated surface, the amount of the end-capping agent is not sufficient, and the hydrolysis resistance to long-term wet heat is insufficient. .
長期間にわたる湿熱に対する耐加水分解性を向上させる方法としては、湿熱が直接接触する構造物の表面に高濃度で末端封鎖加工剤を付与し、かつ構造物の内部にも一定の濃度で末端封鎖加工剤を付与することが考えられている。構造物の表面近傍に高濃度で末端封鎖加工剤を付加し、かつ構造物内部にも末端封鎖加工剤を一定以上の濃度で付加する方法が特許文献4で開示されている。しかしながら、末端封鎖加工剤の被処理物への吸尽効率が低いため、使用濃度が高く、末端封鎖加工剤に係るコストが高くなるという問題がある。 As a method for improving the hydrolysis resistance against wet heat over a long period of time, a high-concentration end-capping agent is applied to the surface of the structure in direct contact with wet heat, and the end-capping is also performed at a constant concentration inside the structure. It is considered to apply a processing agent. Patent Document 4 discloses a method of adding an end-blocking agent at a high concentration near the surface of a structure and adding an end-blocking agent at a certain concentration or more inside the structure. However, since the exhaustion efficiency of the end-capping agent to the object to be processed is low, there is a problem that the use concentration is high and the cost related to the end-capping agent is increased.
本発明は、かかる従来の背景に鑑み、被処理物に対して効率的に末端封鎖加工剤等の加工剤を吸尽させることが可能なポリエステル系繊維構造物の加工剤およびそれを用いた耐加水分解性に優れるポリエステル系繊維構造物の製造方法を提供せんとするものである。 In view of such a conventional background, the present invention provides a processing agent for a polyester fiber structure capable of efficiently exhausting a processing agent such as an end-capping processing agent to an object to be processed, and a resistance using the same.

However, since the effect of the present invention is reduced when the mixing ratio of the polyester fiber is small, the mixing ratio of the polyester fiber is 30% by weight or more. Preferably, 50% by weight or more is more preferable.
本発明においては、ポリエステル系繊維構造物を特定の加工剤で処理する。すなわち、カルボジイミド化合物および脂肪族炭化水素系相溶化剤を、例えばノニオン系界面活性剤またはアニオン系界面活性剤から選ばれる少なくとも1種の界面活性剤にて水または溶剤へ乳化または分散させた加工剤で処理することにより、カルボジイミド化合物がポリエステル系繊維構造物の内部に吸尽される。 In the present invention, the polyester fiber structure is treated with a specific processing agent. That is, a processing agent obtained by emulsifying or dispersing a carbodiimide compound and an aliphatic hydrocarbon-based compatibilizer in water or a solvent with at least one surfactant selected from, for example, a nonionic surfactant or an anionic surfactant. By treating with, the carbodiimide compound is exhausted inside the polyester fiber structure.
加工剤の製造方法としては、カルボジイミド化合物と脂肪族炭化水素系相溶化剤と界面活性剤及び、必要に応じて、有機溶剤と混合し、加熱して、均一な溶融物とした後、放冷することにより、常温で液状の自己乳化型の加工剤を得ることができる。ポリエステル系繊維構造物の加工を行うに際しては、上記自己乳化型の加工剤に水を加えて、攪拌すれば、分散媒が水である加工剤の乳化物を得ることができる。 As a manufacturing method of the processing agent, a carbodiimide compound, an aliphatic hydrocarbon-based compatibilizer, a surfactant, and, if necessary, an organic solvent are mixed, heated to a uniform melt, and then allowed to cool. By doing so, a liquid self-emulsifying type processing agent can be obtained at room temperature. When processing the polyester fiber structure, if the water is added to the self-emulsifying type processing agent and stirred, an emulsion of the processing agent whose dispersion medium is water can be obtained.

The heat treatment time is preferably 15 seconds to 8 minutes. In the case of aliphatic polyester, it is more preferable to heat-treat at 90 to 130 ° C. for 30 seconds to 5 minutes.

When the end-capping treatment is performed simultaneously with the staining, the staining concentration becomes high. Furthermore, since the frequency | count which passes a wet heat treatment process reduces, the hydrolysis of a polyester-type fiber structure is suppressed.
疎水性染料としては、バット染料、インジゴ染料、ナフトール染料等も用いることができる。 As the hydrophobic dye, vat dyes, indigo dyes, naphthol dyes, and the like can also be used.

カルボジイミド化合物の相溶化剤としては、カルボジイミド化合物の溶解度が比較的低く、一方ポリエステル系繊維構造物との親和性に優れることから、脂肪族炭化水素系相溶化剤が用いられる。一般に用いられる線状または環状のアルコール類、ケトン類、エステル類、エーテル類、芳香族炭化水素系溶剤はカルボジイミド化合物の溶解性が良好であるが、溶剤とカルボジイミド化合物の親和性が強く、カルボジイミド化合物のポリエステルへの移行がスムースに起こらないために、カルボジイミド化合物の吸尽率の低下の原因となる。 As the compatibilizer for the carbodiimide compound, an aliphatic hydrocarbon compatibilizer is used because the solubility of the carbodiimide compound is relatively low, while it is excellent in affinity with the polyester fiber structure. Commonly used linear or cyclic alcohols, ketones, esters, ethers, and aromatic hydrocarbon solvents have good carbodiimide compound solubility, but the affinity between the solvent and carbodiimide compound is strong, and carbodiimide compounds Since the transition to polyester does not occur smoothly, it causes a decrease in the exhaustion rate of the carbodiimide compound.
