【発明の属する技術分野】
本発明は、ポリウレタン系弾性繊維材料を含む繊維材料に対して好適な染色異常防止剤、及び該染色異常防止剤を用いるポリウレタン系弾性繊維を含む繊維材料の処理方法に関する。
【０００２】
【従来の技術】
ポリウレタン系弾性繊維材料又はポリウレタン系弾性繊維材料を含む複合繊維材料を加工する際には、湿熱又は乾熱による高温での熱処理が必要である。しかしながら、これらの繊維材料を高温熱処理すると、熱処理時における、繊維材料に付着している油剤、微量金属成分、不飽和脂肪酸などとの相互作用によって、ポリウレタン系弾性繊維に劣化が起こり、染色異常を発生することや、複合されているポリエステル繊維、ナイロン繊維、アクリル繊維などの合成繊維、綿、羊毛などの天然繊維等の非弾性繊維に染色異常が起こるなどの現象が生じ、繊維材料の品質低下が起こることが知られている。従来、染色異常の問題は非弾性繊維のみでも起こりうるが、ポリウレタン系弾性繊維が混在することにより、染色異常が助長される傾向にある。
【０００３】
これらの染色異常を防止する方法として、ポリウレタン系弾性繊維を含有する繊維材料を染色する際に、染色前に酸性浴で前処理する染色方法（特開２００２−６９８６５号公報）が開示されているが、酸性浴で前処理する方法だけでは、上記問題を解決するのに充分ではなく、これらの染色異常を防止する有効な手段が要望されている。

【発明が解決しようとする課題】
本発明は、ポリウレタン系弾性繊維材料を含む繊維材料に対して染色異常を防止する効果を付与する染色異常防止剤、及び該染色異常防止剤を用いたポリウレタン系弾性繊維材料を含む繊維材料の処理方法を提供することを目的とする。
【０００６】

本発明者らは、上記課題を解決するために鋭意検討を重ねた結果、繊維材料に特定のホスホン酸化合物又はその塩を付与することにより、染色異常が防止できることを見い出し、この知見に基づき本発明を完成させた。
【０００７】
すなわち、本発明は、下記式（１）〜（４）のホスホン酸化合物及びそれらの塩からなる群から選ばれる少なくとも１種を含有することを特徴とするポリウレタン系弾性繊維材料を含む繊維材料用の染色異常防止剤を提供する。
【０００８】

【化６】
【化７】
【化８】
また、本発明は、ポリウレタン系弾性繊維材料を含む繊維材料を、前記の染色異常防止剤で処理することを特徴とする繊維材料の処理方法を提供する。
【００１３】
【発明の実施の形態】
本発明に用いられるホスホン酸化合物は、上記式（１）〜（４）のホスホン酸化合物から選ばれる少なくとも１種の化合物である。これらのホスホン酸化合物は合成により又は市販品として入手が可能であり、例えば、キレスト（キレスト（株））、フェリオックス（ライオン（株））、デイクエスト（ソルーシアジャパン社）などの商品名で市販されているものを用いることができる。
【００１４】
また、本発明に用いるホスホン酸塩化合物は、上記式（１）〜（４）のホスホン酸化合物の塩であり、例えば、ナトリウム塩、カリウム塩、アンモニウム塩、有機アミン塩などが挙げられる。そして、これらの塩化合物としては、全ての酸基が中和された完全中和の塩化合物、一部の酸基を残した部分中和の塩化合物が挙げられる。
【００１５】
本発明においては、上記のホスホン酸化合物や部分中和の塩化合物が、染色異常防止の効果の点で、より好ましい。
【００１６】
本発明おいて、染色異常防止剤中の式（１）〜（４）のホスホン酸化合物又はその塩化合物の含有量には特に制限はないが、染色異常防止剤中に５〜１００質量％の量で含有するのが好ましい。含有量が５質量％未満であると加工時の使用量が多くなり、不経済である。
【００１７】
本発明に用いるポリウレタン系弾性繊維材料を含む繊維材料としては、ポリウレタン弾性繊維を含有するポリウレタン系弾性繊維材料又はポリウレタン系弾性繊維材料を含む複合繊維材料である。
【００１８】
本発明に用いられるポリウレタン弾性繊維は、ポリウレタン重合体から紡糸することによって得られる。ここで、ポリウレタン重合体としては、ポリウレタン重合体、ポリウレタン−ウレア共重合体のいずれであってもよいし、ポリウレタン重合体とポリウレタン−ウレア重合体の混合物であってもよい。また、ポリウレタン弾性繊維は、ポリエーテル系ポリウレタン繊維とポリエステル系ポリウレタン繊維のいずれであってもよい。
【００１９】
本発明に用いるポリウレタン系弾性繊維材料は、上記ポリウレタン弾性繊維をそのまま裸糸として用いてもよいし、又はポリエステル繊維、ナイロン繊維、アクリル繊維などの合成繊維及び綿、羊毛などの天然繊維等の従来より知られている繊維の１種以上により被覆されてたものを用いてもよい。
【００２０】
本発明に用いるポリウレタン系弾性繊維材料を含む複合繊維材料としては、上記のポリウレタン系弾性繊維材料と、ポリエステル繊維、ナイロン繊維、アクリル繊維などの合成繊維及び綿、羊毛などの天然繊維等の従来より知られている繊維の１種以上との混紡糸、複合糸、混繊糸、交編布帛、交織布帛、混合不織布などを挙げることができる。
【００２１】
次に、本発明の染色異常防止剤を用いたポリウレタン系弾性繊維材料を含む繊維材料の処理する方法について説明する。ポリウレタン系弾性繊維材料を含む繊維材料の染色異常を防止するには、ポリウレタン系弾性繊維材料を含む繊維材料に染色異常が発生する程の要因となる熱処理が施される前の段階で、本発明の染色異常防止剤を用いてポリウレタン系弾性繊維材料を含む繊維材料を処理すればよい。その処理条件については特に制限はないが、例えば、オープンソーパーなどの連続精練機を用いる場合には、精練槽と別浴で染色異常防止剤の処理を行うこともできるが、全液槽で精練と一緒に行うと効果的である。この時の処理液の温度は、通常の精練と同じ条件の６０〜１００℃であってよく、２０〜６０℃の低温で処理を行うことも可能である。
【００２２】
更に他の一例として、乾熱のヒートセット工程で本発明の染色異常防止剤を使用する場合には、ヒートセット加工機にポリウレタン系弾性繊維材料を含む繊維材料が投入される前の工程に、染色異常防止剤の連続浴槽をもうけてポリウレタン系弾性繊維材料を含む繊維材料に含浸させたり、もしくは霧状で吹き付けるスプレー処理を行ってもよい。
【００２３】
また、染色異常防止剤を処理する際には、液流染色機、ウインス染色機、ジッガー染色機、ビーム染色機、チーズ染色機などといったバッチ式の染色加工機を用いて処理することもできる。この時、染色異常防止だけを目的とする場合には２０〜６０℃の温度でも行うことが可能だが、精練と染色異常防止とを同時に目的とする場合には温度の高い方が精練効果が良好となるので、７０〜１００℃で行うことが好ましい。
【００２４】
また、本発明の染色異常防止剤は単独で用いても、他の各種薬剤と併用してもよい。この時併用できる薬剤としては、例えば、非イオン界面活性剤、カチオン界面活性剤、アニオン界面活性剤などの界面活性剤が挙げられるが、被処理繊維材料に残留の少ないアニオン界面活性剤が望ましい。
【００２５】
本発明の処理方法において、ポリウレタン系弾性繊維材料を含む繊維材料を処理する際の前記式（１）〜（４）のホスホン酸化合物又はこれらの塩化合物の処理浴中の濃度は、例えば、連続処理（ピックアップ：５０〜５００％）の場合、０．００１〜５ｇ／Ｌが好ましく、より好ましくは０．０１〜２ｇ／Ｌである。濃度が０．００１ｇ／Ｌ未満の場合には劣化に起因する染色異常を防止できないおそれがあり、また濃度が５ｇ／Ｌを超えても使用量に見合うだけの染色異常防止の効果が得られず、不経済となるおそれがある。
【００２６】

以下、実施例及び比較例を挙げて本発明を更に説明するが、本発明はこれらの実施例により何ら限定されるものではない。

【発明の効果】
本発明の染色異常防止剤で処理されたポリウレタン系弾性繊維材料を含む繊維材料においては、熱処理に起因する染色異常が効果的に防止でき、これらの繊維材料の品質向上を達成することができる。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an anti-dyeing agent suitable for a fiber material containing a polyurethane-based elastic fiber material, and a method for treating a fiber material containing a polyurethane-based elastic fiber using the anti-dyeing agent.
[0002]
[Prior art]
When processing a polyurethane-based elastic fiber material or a composite fiber material containing a polyurethane-based elastic fiber material, heat treatment at a high temperature by wet heat or dry heat is required. However, when these fiber materials are heat-treated at a high temperature, the polyurethane elastic fibers deteriorate due to the interaction with the oil agent, trace metal components, unsaturated fatty acids, etc. adhering to the fiber material at the time of heat treatment. Deterioration of the quality of fiber materials due to occurrence of abnormalities such as occurrence of dyeing abnormalities in synthetic fibers such as polyester fibers, nylon fibers and acrylic fibers, and natural fibers such as cotton and wool. Is known to happen. Conventionally, the problem of abnormal dyeing can occur only with non-elastic fibers, but the presence of polyurethane-based elastic fibers tends to promote abnormal dyeing.
[0003]
As a method for preventing these abnormal dyeings, a dyeing method (Japanese Patent Laid-Open No. 2002-69865) is disclosed in which a fiber material containing polyurethane-based elastic fibers is pretreated with an acid bath before dyeing. However, the method of pretreatment with an acid bath alone is not sufficient to solve the above problem, and an effective means for preventing these abnormal dyeings is desired.

[Problems to be solved by the invention]
The present invention relates to a dyeing abnormality preventing agent that imparts an effect of preventing a dyeing abnormality to a fiber material including a polyurethane elastic fiber material, and a treatment of the fiber material including the polyurethane elastic fiber material using the dyeing abnormality preventing agent. It aims to provide a method.
[0006]
[Means for Solving the Problems]
As a result of intensive studies in order to solve the above problems, the present inventors have found that a dyeing abnormality can be prevented by applying a specific phosphonic acid compound or a salt thereof to a fiber material. Completed the invention.
[0007]
That is, the present invention is for a fiber material including a polyurethane-based elastic fiber material containing at least one selected from the group consisting of phosphonic acid compounds of the following formulas (1) to (4) and salts thereof: An anti-dyeing agent is provided.
[0008]
[Chemical formula 5]
[Chemical 6]
[Chemical 7]
[Chemical 8]
Moreover, this invention provides the processing method of the fiber material characterized by processing the fiber material containing a polyurethane-type elastic fiber material with the said dyeing | staining abnormality prevention agent.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
The phosphonic acid compound used in the present invention is at least one compound selected from the phosphonic acid compounds of the above formulas (1) to (4). These phosphonic acid compounds can be obtained by synthesis or as a commercial product. For example, under the trade names such as Kyrest (Chillest Co., Ltd.), Feliox (Lion Co., Ltd.), DQuest (Solucia Japan Co., Ltd.), etc. What is marketed can be used.
[0014]
Moreover, the phosphonate compound used for this invention is a salt of the phosphonic acid compound of said formula (1)-(4), For example, sodium salt, potassium salt, ammonium salt, organic amine salt etc. are mentioned. Examples of these salt compounds include completely neutralized salt compounds in which all acid groups have been neutralized, and partially neutralized salt compounds in which some of the acid groups have been left.
[0015]
In the present invention, the above-described phosphonic acid compounds and partially neutralized salt compounds are more preferable in terms of the effect of preventing staining abnormality.
[0016]
In the present invention, the content of the phosphonic acid compounds of the formulas (1) to (4) or the salt compounds thereof in the dyeing abnormality preventing agent is not particularly limited, but 5 to 100% by mass in the dyeing abnormality preventing agent. It is preferable to contain by quantity. If the content is less than 5% by mass, the amount used during processing increases, which is uneconomical.
[0017]
The fiber material containing the polyurethane elastic fiber material used in the present invention is a polyurethane elastic fiber material containing a polyurethane elastic fiber or a composite fiber material containing a polyurethane elastic fiber material.
[0018]
The polyurethane elastic fiber used in the present invention is obtained by spinning from a polyurethane polymer. Here, the polyurethane polymer may be either a polyurethane polymer or a polyurethane-urea copolymer, or may be a mixture of a polyurethane polymer and a polyurethane-urea polymer. The polyurethane elastic fiber may be either a polyether-based polyurethane fiber or a polyester-based polyurethane fiber.
[0019]
The polyurethane elastic fiber material used in the present invention may use the polyurethane elastic fiber as a bare yarn as it is, or a conventional synthetic fiber such as polyester fiber, nylon fiber, acrylic fiber, and natural fiber such as cotton and wool. You may use what was coat | covered with 1 or more types of the more well-known fiber.
[0020]
As the composite fiber material including the polyurethane-based elastic fiber material used in the present invention, the above-mentioned polyurethane-based elastic fiber material, synthetic fibers such as polyester fiber, nylon fiber, and acrylic fiber, and natural fibers such as cotton and wool are conventionally used. Mention may be made of blended yarns, composite yarns, blended yarns, knitted fabrics, woven fabrics, mixed nonwoven fabrics and the like with one or more types of known fibers.
[0021]
Next, a method for treating a fiber material containing a polyurethane elastic fiber material using the dyeing abnormality preventing agent of the present invention will be described. In order to prevent the abnormal dyeing of the fiber material containing the polyurethane elastic fiber material, the present invention is performed at a stage before the heat treatment that causes the dyeing abnormality to occur in the fiber material containing the polyurethane elastic fiber material. The fiber material containing the polyurethane-based elastic fiber material may be treated using the dyeing abnormality preventing agent. The treatment conditions are not particularly limited. For example, when a continuous scouring machine such as an open soaper is used, the dyeing abnormality inhibitor can be treated in a separate bath from the scouring tank. It is effective when done together. The temperature of the treatment liquid at this time may be 60 to 100 ° C. under the same conditions as normal scouring, and the treatment can be performed at a low temperature of 20 to 60 ° C.
[0022]
As another example, when using the dyeing abnormality preventing agent of the present invention in a dry heat setting process, before the fiber material containing polyurethane-based elastic fiber material is put into the heat setting machine, A continuous bath of a dyeing abnormality preventing agent may be provided to impregnate a fiber material containing a polyurethane-based elastic fiber material, or spraying may be performed in a mist form.
[0023]
Moreover, when processing the dyeing abnormality preventing agent, it can also be processed using a batch-type dyeing machine such as a liquid dyeing machine, a wins dyeing machine, a jigger dyeing machine, a beam dyeing machine, or a cheese dyeing machine. At this time, if the purpose is only to prevent abnormal dyeing, it can be carried out at a temperature of 20 to 60 ° C. However, if the purpose is to simultaneously refine and prevent abnormal dyeing, the higher the temperature, the better the scouring effect. Therefore, it is preferable to carry out at 70-100 degreeC.
[0024]
Moreover, the staining abnormality preventing agent of the present invention may be used alone or in combination with other various drugs. Examples of agents that can be used at this time include surfactants such as nonionic surfactants, cationic surfactants, and anionic surfactants, and anionic surfactants that have little residue in the fiber material to be treated are desirable.
[0025]
In the treatment method of the present invention, the concentration of the phosphonic acid compounds of the above formulas (1) to (4) or their salt compounds in the treatment bath when treating a fiber material containing a polyurethane-based elastic fiber material is, for example, continuous. In the case of processing (pickup: 50 to 500%), 0.001 to 5 g / L is preferable, and 0.01 to 2 g / L is more preferable. If the concentration is less than 0.001 g / L, it may not be possible to prevent abnormal dyeing due to deterioration, and even if the concentration exceeds 5 g / L, the effect of preventing abnormal dyeing sufficient for the amount used cannot be obtained. There is a risk of becoming uneconomical.
