　本実施形態の処理剤、水性液、及びビスコースレーヨンの作用及び効果について説明する。 The actions and effects of the treatment agent, aqueous liquid, and viscose rayon of the present embodiment will be described.
　（１）本実施形態の処理剤又は水性液は、亜鉛化合物を含有する。したがって、処理剤から水性液を調製する際及び水性液を使用する際の泡立ち、特に水性液を付着させる工程での泡立ちを低減できる。また、界面活性剤は、処理剤から得られるエマルションの安定性を向上させ、水性液の外観を向上させる。 (1) The treatment agent or aqueous liquid of the present embodiment contains a zinc compound. Therefore, it is possible to reduce foaming when preparing the aqueous liquid from the treatment agent and when using the aqueous liquid, particularly in the step of adhering the aqueous liquid. In addition, the surfactant improves the stability of the emulsion obtained from the treatment agent and improves the appearance of the aqueous liquid.
　（２）本実施形態の処理剤又は水性液は、特に浸漬法、スプレー法、シャワー法、滴下・流下法等の泡立ちやすい使用方法で繊維に付与される場合であっても、泡立ちを低減できる。 (2) The treatment agent or aqueous liquid of the present embodiment can reduce foaming even when it is applied to fibers by a method of use that facilitates foaming, such as a dipping method, a spray method, a shower method, or a dropping / flowing method. ..
　（３）本実施形態の処理剤又は水性液は、エマルションの安定性を向上させ、泡立ちを低減できる。したがって、処理剤又は水性液をビスコースレーヨンに対して均質に付与することができ、不織布製造特性をより向上させる。 (3) The treatment agent or aqueous liquid of the present embodiment can improve the stability of the emulsion and reduce foaming. Therefore, the treatment agent or the aqueous liquid can be uniformly applied to the viscose rayon, and the non-woven fabric manufacturing characteristics are further improved.
　上記実施形態は、以下のように変更して実施できる。上記実施形態、及び、以下の変更例は、技術的に矛盾しない範囲で互いに組み合わせて実施できる。 The above embodiment can be modified and implemented as follows. The above embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
　・上記実施形態の処理剤又は水性液には、本発明の効果を阻害しない範囲内において、処理剤又は水性液の品質保持のための安定化剤や制電剤として、上記以外の界面活性剤、帯電防止剤、つなぎ剤、酸化防止剤、紫外線吸収剤、ｐＨ調整剤等の通常処理剤又は水性液に用いられる成分をさらに配合してもよい。 -The treatment agent or aqueous liquid of the above embodiment includes surfactants other than the above as stabilizers and antistatic agents for maintaining the quality of the treatment agent or aqueous liquid within a range that does not impair the effects of the present invention. , Antistatic agents, binders, antioxidants, UV absorbers, pH adjusters and other conventional treatment agents or components used in aqueous solutions may be further added.
　・上記実施形態の水性液の調製時に用いられる水の種類としては、特に限定されず、不純物をほとんど含まない蒸留水、Ｃａイオン、Ｍｇイオン等を含有する硬水又は軟水であってもよい。Ｃａイオン、Ｍｇイオンによる泡立ち低減効果が得られる観点から軟水又は硬水が好ましく適用される。水性液中におけるＣａイオン等の金属イオン濃度は、泡立ち低減効果の発揮の観点から、０．１ｐｐｍ～１００００ｐｐｍが好ましく、０．１ｐｐｍ～１００ｐｐｍがより好ましい。 -The type of water used when preparing the aqueous liquid of the above embodiment is not particularly limited, and may be distilled water containing almost no impurities, hard water containing Ca ions, Mg ions, or the like, or soft water. Soft water or hard water is preferably applied from the viewpoint of obtaining the effect of reducing foaming by Ca ions and Mg ions. The concentration of metal ions such as Ca ions in the aqueous liquid is preferably 0.1 ppm to 10000 ppm, more preferably 0.1 ppm to 100 ppm, from the viewpoint of exerting the foaming reducing effect.
　また、処理剤には、使用する界面活性剤、油の成分により、遷移金属イオンが含まれることがある。例えば、エステルを合成する際に触媒としてＴｉ、Ｍｏ、Ｍｎ、Ｓｎ等の遷移金属が用いられるため、残留遷移金属イオンが処理剤中に含まれることがある。遷移金属イオンもＣａイオン等と同様に泡立ち低減効果が得られる。水性液中における遷移金属イオン濃度は、泡立ち低減効果の発揮の観点から、０．１ｐｐｍ～１００００ｐｐｍが好ましく、０．１ｐｐｍ～１０００ｐｐｍがより好ましい。 In addition, the treatment agent may contain transition metal ions depending on the surfactant and oil components used. For example, since a transition metal such as Ti, Mo, Mn, or Sn is used as a catalyst when synthesizing an ester, residual transition metal ions may be contained in the treatment agent. Similar to Ca ions, transition metal ions also have a foaming reducing effect. The transition metal ion concentration in the aqueous liquid is preferably 0.1 ppm to 10000 ppm, more preferably 0.1 ppm to 1000 ppm, from the viewpoint of exhibiting the foaming reduction effect.
　以下、本発明の構成及び効果をより具体的に説明するため、実施例等を挙げるが、本発明がこれらの実施例に限定されるというものではない。尚、以下の実施例及び比較例の説明において、部は質量部を、また％は質量％を意味する。 Hereinafter, examples and the like will be given in order to more specifically explain the configuration and effect of the present invention, but the present invention is not limited to these examples.
