Description
【０００１】
【産業上の利用分野】
本発明は解舒性と平滑性に優れる弾性繊維の処理剤および弾性繊維に関する。
【０００２】
【従来の技術】
特開昭６０−８１３７４号公報には、ステアリン酸Ｚｎやステアリン酸Ｍｇなどを用いた弾性糸用油剤が記載されている。特開昭６０−８１３７４号公報には、炭素数が１０〜２０の高級脂肪酸の金属塩を含有した繊維糸状物用ストレート油剤組成物が記載されている。
【０００３】
【発明が解決しようとする課題】
弾性繊維用処理剤は、解舒性および平滑性を付与するためにステアリン酸Ｚｎやステアリン酸Ｍｇを用いてきたが、ステアリン酸の金属塩単独ではその結晶が硬くなりすぎて、解舒性・平滑性が充分に発揮されていないのが実情である。また、ステアリン酸の金属塩は通常２個の水和水を有することにより安定化するが、この水和水はイソシアネートの残存しているポリウレタンウレア糸状に接触すると、イソシアネートを失活させてしまい、糸の物性が充分に出ないといった欠点があった。
【０００４】
【課題を解決するための手段】
本発明の処理剤は、ベース成分が、シリコーンオイル、鉱物油およびエステル油から選択され、炭素数１６の高級脂肪酸の金属塩と炭素数１８の高級脂肪酸の金属塩の混合比が５：９５〜５０：５０の比率で混合され、かつ水和水が０．５〜５．０％に制御された高級脂肪酸金属塩をベース成分に対し０．０１〜１０重量％配合し、３０℃における粘度が３〜３０ｍｍ２／ｓである弾性繊維用処理剤である。また、本発明は上記処理剤が０．１〜１５重量％弾性繊維に対し付与されていることを特徴とする弾性繊維である。
【０００６】
本発明は、ベース成分がシリコーンオイル、鉱物油およびエステル油より選ばれる。シリコーンオイルをベース成分として、１００％用いると本発明に配合する高級脂肪酸の沈降性が悪くなるので、好ましくは、鉱物油またはエステル油を３０重量％以上より好ましくは５０重量％以上使用すると解舒性・平滑性の向上効果が大きい。
【０００７】
本発明の処理剤には、炭素数１６の高級脂肪酸の金属塩と炭素数１８の高級脂肪酸の金属塩が混合比５：９５〜５０：５０の比率で混合される必要がある。
炭素数１８の高級脂肪酸の金属塩に炭素数１６の高級脂肪酸の金属塩を上記割合で混合することにより、高級脂肪酸の金属塩の硬さが程よいレベルになるためか、解舒性および平滑性に優れる処理剤になる。混合比率は２０：８０〜４０；６０がより好ましい。
高級脂肪酸の金属塩の対になる金属としては、２価の金属が好ましく、例えばＣａ、亜鉛、Ｍｇ、Ａｌ、Ｂａ等が挙げられる。
さらに、本発明は、水和水が０．５〜５％に制御された高級脂肪酸金属塩を０．０１〜１０重量％使用する。水和水が５％以上では、水和水によるポリウレタンウレア弾性繊維の糸物性の低下が起こる。水和水が０．５％以下では、高級脂肪酸の吸湿性が高くなり、処理剤中での沈降安定性が悪くなる。好ましくは、水和水が１〜４．０％より好ましくは１．５〜３．５％である。高級脂肪酸金属塩の処理剤中の含有量は０．０１％以下では本発明の効果が発揮されず、１０％以上では、処理剤粘度が高くなりすぎる。好ましくは、０．１〜５％である。使用する高級脂肪酸金属塩の平均粒子径としては、０．０１〜５μｍが好ましい、より好ましくは０．１〜３μｍである。５μｍより大きいと解舒性が充分でない場合があり、０．０１μｍより小さい場合も解舒性の効果が発揮されなくなる場合がある。
本発明の処理剤は３０℃における粘度が通常３〜５０ｍｍ２／ｓが好ましい。３ｍｍ２／ｓ未満では、処理剤の揮発が問題となる場合があり、５０ｍｍ２／ｓを超えると平滑性に劣る場合がある。
また、本発明の処理剤には従来公知の変性シリコーン（アルキル変性シリコーン、エステル変性シリコーン、ポリエーテル変性シリコーン、アミド変性シリコーン、アミノ変性シリコーン、カルビノール変性シリコーン、カルボキシ変性シリコーン、メルカプト変性シリコーン、リン酸変性シリコーン、エポキシ変性シリコーン、ＭＱシリコーンレジン、ＭＱＴシリコーンレジン、Ｔシリコーンレジン等）やつなぎ剤、制電剤、酸化防止剤、紫外線吸収剤、滑剤等、通常弾性繊維の処理剤に用いられる成分を配合することができる。
【０００８】
本発明の処理剤は、通常、弾性繊維に対して０．１〜１５重量％付与される。
本発明に言う弾性繊維とは、ＰＴＭＧやポリエステルジオールと有機ジイソシアネートを反応させ、次いで、１，４ブタンジオール、エチレンジアミン、プロピレンジアミンなどで鎖延長した、ポリウレタンあるいはポリウレタンウレアから構成されるものがある。
【０００９】
【実施例】
以下実施例により本発明を具体的に説明する。
なお具体例における、各処理剤の特性の評価は次の方法に従って行った。
【００１０】
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。 巻き取り速度を一定速度にセットした後、ローラー（３）及び（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ないため解舒点（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（％）＝（巻取速度比−解舒速度）／解舒速度Ｘ１００ （式１）
編成張力：
図２において、チーズ（８）から縦取りした弾性糸（９）をコンペンセーター（１０）を経てローラー（１１）、編み針（１２）を介して、Ｕゲージ（１３）に付したローラー（１４）を経て速度計（１５）、巻き取りローラー（１６）に連結する。速度計（１５）での走行速度が定速（例えば、１０ｍ／分、１００ｍ／分）になるように巻き取りローラーの回転速度を調整して、巻き取りローラーに巻き取り、そのときの編成張力をＵゲージ（１３）で測定し、繊維／編み針間の摩擦（ｇ）を計測する。走行糸条より１ｃｍのところで春日式電位差測定装置（１７）で発生静電気を測定する。
ローラー静電気：
解舒速度比測定機の解舒側にチーズをセットし、５０ｍ／分の周速で回転させ、チーズ上２ｃｍのところにおいて、春日式電位差測定装置で、回転を始めて１時間後の発生静電気を測定する
強度・伸度：ＪＩＳ−１０１３に準じて測定した。
粘度：キャノンフェンスケ粘度計により３０℃で測定した。
平均粒子径：ＨＯＲＩＢＡ ＬＡ−９１０により測定した。

[Industrial applications]
The present invention relates to a treatment agent for an elastic fiber having excellent unwinding properties and smoothness, and an elastic fiber.
[0002]
[Prior art]
JP-A-60-81374 discloses an oil agent for elastic yarns using Zn stearate, Mg stearate, or the like. JP-A-60-81374 discloses a straight oil composition for a fibrous thread containing a metal salt of a higher fatty acid having 10 to 20 carbon atoms.
[0003]
[Problems to be solved by the invention]
The treatment agent for elastic fiber has used Zn stearate or Mg stearate to impart unwinding property and smoothness. However, the metal salt of stearic acid alone becomes too hard for the crystal, and the unwinding property is increased. The fact is that the smoothness is not sufficiently exhibited. In addition, the metal salt of stearic acid is usually stabilized by having two waters of hydration, but this water of hydration deactivates the isocyanate when it comes into contact with the polyurethane urea thread where the isocyanate remains, There was a disadvantage that the physical properties of the yarn were not sufficiently obtained.
[0004]
[Means for Solving the Problems]
In the treating agent of the present invention, the base component is selected from silicone oil, mineral oil, and ester oil, and the mixing ratio of the metal salt of a higher fatty acid having 16 carbon atoms to the metal salt of a higher fatty acid having 18 carbon atoms is 5: 95- A higher fatty acid metal salt mixed at a ratio of 50:50 and water of hydration controlled to 0.5 to 5.0% is blended in an amount of 0.01 to 10% by weight based on the base component, and the viscosity at 30 ° C is adjusted. It is a treatment agent for elastic fibers of 3 to 30 mm 2 / s. Further, the present invention is an elastic fiber characterized in that the above-mentioned treating agent is added to 0.1 to 15% by weight of the elastic fiber.
[0006]
In the present invention, the base component is selected from silicone oil, mineral oil and ester oil. If 100% of silicone oil is used as a base component, the sedimentation of higher fatty acids to be blended in the present invention is deteriorated. Therefore, if mineral oil or ester oil is used at 30% by weight or more, more preferably 50% by weight or more, unwinding is performed. The effect of improving the smoothness and smoothness is great.
[0007]
In the treating agent of the present invention, a metal salt of a higher fatty acid having 16 carbon atoms and a metal salt of a higher fatty acid having 18 carbon atoms need to be mixed at a mixing ratio of 5:95 to 50:50.
This is because mixing the metal salt of a higher fatty acid having 16 carbon atoms with the metal salt of a higher fatty acid having 18 carbon atoms at the above-mentioned ratio makes the hardness of the metal salt of the higher fatty acid moderate. It becomes an excellent treatment agent. The mixing ratio is more preferably from 20:80 to 40; 60.
As a metal that forms a pair with the metal salt of a higher fatty acid, a divalent metal is preferable, and examples thereof include Ca, zinc, Mg, Al, and Ba.
Furthermore, the present invention uses 0.01 to 10% by weight of a higher fatty acid metal salt whose hydration water is controlled to 0.5 to 5%. When the hydration water is 5% or more, the thread physical properties of the polyurethane urea elastic fiber are reduced by the hydration water. When the water of hydration is 0.5% or less, the hygroscopicity of the higher fatty acid increases, and the sedimentation stability in the treating agent deteriorates. Preferably, the hydration water is from 1 to 4.0%, more preferably from 1.5 to 3.5%. If the content of the higher fatty acid metal salt in the treating agent is 0.01% or less, the effect of the present invention is not exhibited, and if it is 10% or more, the treating agent viscosity becomes too high. Preferably, it is 0.1 to 5%. The average particle size of the higher fatty acid metal salt used is preferably from 0.01 to 5 μm, more preferably from 0.1 to 3 μm. If it is larger than 5 μm, the unwinding property may not be sufficient, and if it is smaller than 0.01 μm, the unwinding effect may not be exhibited.
The treatment agent of the present invention preferably has a viscosity at 30 ° C. of usually 3 to 50 mm 2 / s. If it is less than 3 mm 2 / s, volatilization of the treating agent may become a problem, and if it exceeds 50 mm 2 / s, the smoothness may be poor.
The treating agent of the present invention includes a conventionally known modified silicone (alkyl-modified silicone, ester-modified silicone, polyether-modified silicone, amide-modified silicone, amino-modified silicone, carbinol-modified silicone, carboxy-modified silicone, mercapto-modified silicone, phosphorus Components usually used for treating elastic fibers, such as acid-modified silicone, epoxy-modified silicone, MQ silicone resin, MQT silicone resin, and T silicone resin), binders, antistatic agents, antioxidants, ultraviolet absorbers, lubricants, and the like. Can be blended.
[0008]
The treating agent of the present invention is usually added in an amount of 0.1 to 15% by weight based on the elastic fiber.
The elastic fibers referred to in the present invention include those made of polyurethane or polyurethane urea obtained by reacting PTMG or polyester diol with an organic diisocyanate, and then chain-extending with 1,4-butanediol, ethylenediamine, propylenediamine, or the like.
[0009]

Hereinafter, the present invention will be described specifically with reference to examples.
In addition, the evaluation of the characteristic of each processing agent in the specific example was performed according to the following method.

In FIG. 1, a fiber cheese (1) provided with a treatment agent is set on the unwinding side of the unwinding speed ratio measuring machine, and a winding paper tube (2) is set. After setting the winding speed to a constant speed, the rollers (3) and (4) are simultaneously activated. In this state, since little tension is applied to the yarn (5), the yarn is stuck on the cheese and does not separate, so that the unwinding point (6) is in the state shown in FIG. By changing the unwinding speed, the unwinding point (6) of the yarn (5) from the cheese changes, and 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 determined by
Unwinding speed ratio (%) = (winding speed ratio-unwinding speed) / unwinding speed X100 (Formula 1)
Knitting tension:
In FIG. 2, a roller (14) attached to a U gauge (13) through a compensator (10), a roller (11), and a knitting needle (12) is applied to an elastic thread (9) taken from the cheese (8). Via a speedometer (15) and a winding roller (16). The rotation speed of the winding roller is adjusted so that the traveling speed on the speedometer (15) becomes a constant speed (for example, 10 m / min, 100 m / min), the winding is performed on the winding roller, and the knitting tension at that time is adjusted. Is measured with a U gauge (13), and the friction (g) between the fiber and the knitting needle is measured. At 1 cm from the running yarn, the generated static electricity is measured by a Kasuga potential difference measuring device (17).
Roller static electricity:
The cheese was set on the unwinding side of the unwinding speed ratio measuring machine, and rotated at a peripheral speed of 50 m / min. At 2 cm above the cheese, the static electricity generated 1 hour after the rotation was started using a Kasuga-type potential difference measuring device was measured. Strength / elongation to be measured: Measured according to JIS-1013.
Viscosity: Measured at 30 ° C. with a Cannon-Fenske viscometer.
Average particle size: Measured by HORIBA LA-910.
