Description
本発明は、弾性繊維用処理剤及び該処理剤が付与された弾性繊維に関する。 The present invention relates to a treatment agent for elastic fibers and elastic fibers to which the treatment agent is applied.
弾性繊維は、紡糸工程において、処理剤を付与した後、チーズ形状に巻き取られ、捲糸体（以下、チーズということもある）となる。弾性繊維は、粘弾性を有するために膠着し易い繊維である。特に捲糸体の内層部においては、巻き取り時にかかる圧力により膠着が経時的に進行する。そのため、弾性繊維捲糸体を使用する際、解舒不良となり糸切れを引き起こす。この解舒不良を改良するために、種々の弾性繊維用処理剤が開発されている。
例えば、特許文献１には、シリコーンレジン（ＭＱレジン）を含有する弾性繊維用処理剤が記載され、特許文献２には、カルボキシアミド変性シリコーンを含有し、高級脂肪酸マグネシウム塩の凝集や沈降を抑えた弾性繊維用処理剤が記載されている。特許文献３には、平均粒子径０．０１〜５μｍにあり、且つ針状である高級脂肪酸の金属塩を含有した弾性繊維用処理剤が記載されている。In the spinning process, the elastic fiber is wound into a cheese shape after applying a treatment agent to form a wound body (hereinafter, also referred to as cheese). Elastic fibers are fibers that are easily stuck because they have viscoelasticity. In particular, in the inner layer portion of the wound body, sticking progresses over time due to the pressure applied during winding. Therefore, when the elastic fiber wound body is used, the unwinding is poor and the yarn breaks. Various treatment agents for elastic fibers have been developed in order to improve this unwinding defect.
For example, Patent Document 1 describes a treatment agent for elastic fibers containing a silicone resin (MQ resin), and
しかし、これら従来技術に記載された弾性繊維用処理剤は、捲糸体の内層部における繊維の膠着防止性には優れるものの、その処理剤の有する繊維／繊維間摩擦の低下作用により、捲糸体の外層部においては捲き崩れが生じたり、綾落ちなどの解舒性不良を生じたりするという問題が発生する場合があった。
基本的に上記捲糸体の内層部における繊維の膠着防止性と、外層部における捲き崩れ防止性は、一方を重視すると他方が悪化するというトレードオフの関係にあり、従来技術においては両者のバランスを取りつつ適用するというのが実情であり、両者を満足する弾性繊維用処理剤が切望されていた。However, although the treatment agents for elastic fibers described in these prior arts are excellent in preventing fiber sticking in the inner layer portion of the winding body, the treatment agent has a fiber-to-fiber friction reducing action, so that the winding yarn is wound. In the outer layer of the body, there may be a problem that the roll collapses or the unfoldability such as the twill drop occurs.
Basically, there is a trade-off relationship between the fiber sticking prevention property in the inner layer portion of the wound yarn body and the winding collapse prevention property in the outer layer portion, that the other becomes worse when one is emphasized, and in the prior art, the balance between the two. The actual situation is that it is applied while taking the above, and a treatment agent for elastic fibers that satisfies both of them has been eagerly desired.
従って、本発明の目的は、捲糸体の内層部における繊維の膠着防止性と、外層部における捲き崩れ防止性の両方に優れる弾性繊維用処理剤及び該処理剤が付与された弾性繊維を提供することにある。 Therefore, an object of the present invention is to provide an elastic fiber treatment agent having excellent fiber sticking prevention property in the inner layer portion of the wound yarn body and curl collapse prevention property in the outer layer portion, and an elastic fiber to which the treatment agent is applied. To do.
本発明者らは、上記実情に鑑み、捲糸体の内層部における繊維の膠着防止性と、外層部における捲き崩れ防止性を両立できる弾性繊維用処理剤について鋭意検討した結果、特定のベース成分と、特定の成分（Ｂ）を含有する弾性繊維用処理剤であれば上記課題を解決できる事を見出し、本発明に到達した。
すなわち、本発明の弾性繊維用処理剤は、鉱物油（Ａ１）、シリコーン油（Ａ２）及びエステル油（Ａ３）から選ばれる少なくとも１種のベース成分（Ａ）と、塩基性のアルカリ土類金属スルホネートである成分（Ｂ）とを含む。In view of the above circumstances, the present inventors have diligently studied a treatment agent for elastic fibers that can both prevent fiber sticking in the inner layer portion of the wound yarn body and prevent rolling collapse in the outer layer portion, and as a result, a specific base component. Then, they found that the above problem could be solved by a treatment agent for elastic fibers containing a specific component (B), and arrived at the present invention.
That is, the treatment agent for elastic fibers of the present invention contains at least one base component (A) selected from mineral oil (A1), silicone oil (A2) and ester oil (A3), and a basic alkaline earth metal. Includes component (B) which is a sulfonate.

前記成分（Ｂ）の全塩基価が１〜７００ＫＯＨｍｇ／ｇであると好ましい。
処理剤に対する前記成分（Ｂ）の重量割合が０．１〜２０重量％であると好ましい。The sulfonic acid constituting the component (B) is preferably an alkyl aromatic sulfonic acid having an average molecular weight of 350 g / mol to 700 g / mol.
The total base value of the component (B) is preferably 1 to 700 KOHmg / g.
The weight ratio of the component (B) to the treatment agent is preferably 0.1 to 20% by weight.
本発明の弾性繊維は、弾性繊維本体に、上記処理剤が付与されてなる。 The elastic fiber of the present invention is obtained by applying the above-mentioned treatment agent to the elastic fiber body.
本発明の弾性繊維用処理剤が付与されてなる弾性繊維は、捲糸体の内層部における繊維の膠着防止性と、外層部における捲き崩れ防止性の両方に優れる。 The elastic fiber to which the treatment agent for elastic fiber of the present invention is applied is excellent in both the anti-sticking property of the fiber in the inner layer portion of the winding body and the anti-rolling property in the outer layer portion.

The component (B) is a component that simultaneously exerts two functions of preventing sticking and suppressing rolling collapse in the inner layer portion of the elastic fiber wound body.
The component (B) is dissolved and dispersed in the base oil.
成分（Ｂ）は、弾性繊維の表面に効率よく吸着し、弾性繊維同士の直接的な接触を妨げるため、捲糸体の内層部における膠着を防止すると考えられる。成分（Ｂ）が弾性繊維の表面に効率よく吸着する理由は定かではないが、高極性であるため、弾性繊維表面に吸着し、被覆するためと推定している。 It is considered that the component (B) efficiently adsorbs to the surface of the elastic fibers and prevents the elastic fibers from directly contacting each other, thereby preventing sticking in the inner layer portion of the wound yarn. The reason why the component (B) is efficiently adsorbed on the surface of the elastic fiber is not clear, but it is presumed that the component (B) is adsorbed on the surface of the elastic fiber and coated because of its high polarity.

以下、実施例及び比較例により本発明を具体的に説明するが、本発明はここに記載した実施例に限定されるものではない。なお、以下の実施例に示される「パーセント（％）」及び「部」は、特に限定しない限り、「重量％」及び「重量部」を示す。なお、実施例及び比較例において、弾性繊維用処理剤の各特性の評価は次の方法に従って行った。 Hereinafter, the present invention will be specifically described with reference to Examples and Comparative Examples, but the present invention is not limited to the Examples described here. In addition, "percent (%)" and "part" shown in the following Examples indicate "% by weight" and "part by weight" unless otherwise specified. In the examples and comparative examples, the evaluation of each property of the elastic fiber treatment agent was carried out according to the following method.
（解舒速度比）
図１において、解舒速度比測定機の解舒側に処理剤を付与した繊維のチーズ（１）をセットし、巻き取り側紙管（２）をセットする。巻取速度を一定速度にセットした後、ローラー（３）および（４）を同時に起動させる。この状態では糸（５）に張力はほとんどかからないため、糸はチーズ上で膠着して離れず、解舒点（６）は図１に示す状態にある。解舒速度を変えることによって、チーズからの糸（５）の解舒点（６）が変わるので、この点がチーズとローラーとの接点（７）と一致するように解舒速度を設定する。解舒速度比は下記式（１）によって求める。この値が小さいほど、解舒性が良いことを示す。
解舒速度比（％）＝（（巻取速度−解舒速度）／解舒速度）×１００（１）
経時後の解舒速度比とは、２０℃６５％ＲＨの条件下で、６ヶ月経時後の解舒速度比を示す。(Unwinding speed ratio)
In FIG. 1, the fiber cheese (1) to which the treatment agent is applied is set on the unwinding side of the unwinding speed ratio measuring machine, and the take-up side paper tube (2) is set. After setting the take-up speed to a constant speed, the rollers (3) and (4) are started at the same time. In this state, almost no tension is applied to the thread (5), so that the thread sticks on the cheese and does not separate, and the unwinding point (6) is in the state shown in FIG. Since the unwinding point (6) of the thread (5) from the cheese changes by changing the unwinding speed, the unwinding speed is set so that this point coincides with the contact point (7) between the cheese and the roller. The unwinding speed ratio is calculated by the following equation (1). The smaller this value is, the better the solvability is.
Unwinding speed ratio (%) = ((winding speed-unwinding speed) / unwinding speed) x 100 (1)
The unwinding rate ratio after aging indicates the unwinding rate ratio after 6 months under the condition of 20 ° C. and 65% RH.
（繊維間摩擦係数（Ｆ／ＦμＳ））
図３において、処理剤が付与されたポリウレタン弾性繊維のモノフィラメントを５０〜６０ｃｍ程取り、一方の端に荷重Ｔ１（２０）を吊り、ローラー（１９）を介して、Ｕゲージ（１８）にもう一方の端を掛けて定速（例えば、３ｃｍ／分）で引っ張り、そのときの２次張力Ｔ２をＵゲージ（１８）で測定し、下式（２）により、繊維間摩擦係数を求める。
摩擦係数（Ｆ／ＦμＳ）＝１／θ・ｌｎ（Ｔ２／Ｔ１）式（２）
（式（２）において、θ＝２π、ｌｎ＝自然対数、Ｔ１は２２ｄｔｅｘ当り１ｇ）(Friction coefficient between fibers (F / FμS))
In FIG. 3, a monofilament of polyurethane elastic fiber to which a treatment agent is applied is taken about 50 to 60 cm, a load T1 (20) is suspended at one end, and the other is attached to a U gauge (18) via a roller (19). The end of the fiber is hung and pulled at a constant speed (for example, 3 cm / min), the secondary tension T2 at that time is measured with a U gauge (18), and the coefficient of friction between fibers is obtained by the following equation (2).
Friction coefficient (F / FμS) = 1 / θ · ln (T2 / T1) equation (2)
(In equation (2), θ = 2π, ln = natural logarithm, T1 is 1 g per 22 dtex)

After that, the cheese was wound on a bobbin at a speed of 500 m / min to obtain 44 dtex monofilament cheese (rolling amount 400 g). The obtained cheese was left in an atmosphere of 35 ° C. and 50% RH for 48 hours for evaluation. The evaluation results of the oil agent performance are shown in Tables 2 and 3. The components used in Tables 1 and 2 are as follows.
Regarding the method for measuring the total base value of the basic metal sulfonate component (B), first, the basic metal sulfonate component (B) was separated from the treatment agent by a rubber membrane dialysis method, and the separated basic metal sulfonate component (B) was separated. The total base value of B) was measured by JIS K2501 (hydrochloric acid method).

表１〜３から分かるように、実施例１〜１１の場合は鉱物油（Ａ１）、シリコーン油（Ａ２）及びエステル油（Ａ３）から選ばれる少なくとも１種のベース成分（Ａ）と、塩基性のアルカリ土類金属スルホネートである成分（Ｂ）を含む弾性繊維用処理剤を用いているので、捲糸体の内層部における繊維の膠着防止性、外層部における捲き崩れ防止性に優れる。
比較例１〜１３の場合はチーズの内層部の解舒速度比が大きい、内外層差が大きく均一解舒性が不足している、繊維間摩擦係数が小さいなどの理由から、本願の課題である捲糸体の内層部における繊維の膠着防止性、外層部における捲き崩れ防止性のいずれかが解決できていない。比較例９〜１３については特許文献４に記載のスルホン酸塩系のアニオン界面活性剤を用いているが、いずれも中性の金属スルホネートであり、成分（Ｂ）を用いていないために内外層差が大きく均一解舒性が不足している。As can be seen from Tables 1 to 11, in the case of Examples 1 to 11, at least one base component (A) selected from mineral oil (A1), silicone oil (A2) and ester oil (A3) and basicity. Since the treatment agent for elastic fibers containing the component (B) which is an alkaline earth metal sulfonate is used, it is excellent in the fiber sticking prevention property in the inner layer portion of the winding body and the rolling collapse prevention property in the outer layer portion.
In the case of Comparative Examples 1 to 13, the problem of the present application is that the unwinding rate ratio of the inner layer portion of the cheese is large, the difference between the inner and outer layers is large, the uniform unwinding property is insufficient, and the coefficient of friction between fibers is small. Either the fiber sticking prevention property in the inner layer portion of a certain wound body or the winding collapse prevention property in the outer layer portion has not been solved.
