【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、ポリエステル系繊維材料用精練染色助剤に関
し、特に未精練のもしくは精練が不十分なポリエステル
系繊維を分散染料を用いて染色する際に高品位な染色物
をあたえる染色助剤に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a scouring dyeing aid for polyester fiber materials, and particularly for dyeing unscoured or insufficiently scoured polyester fibers using a disperse dye. This relates to dyeing aids that provide high-quality dyed products.
〔従来の技術］
一般に、ポリエステル系繊維の染色は、十分な精練工程
を経た被染色物を用いて、１１０〜１４０°Ｃの高温高
圧の下、弱酸性領域で分散染料を用いて染色する。この
際、分散染料の分散不十分からくる不均染を解消するた
め、さらには緩染効果或は移染効果を促進させて均染性
を向上させるために、分散均染剤を染色浴に添加する。[Prior Art] Generally, polyester fibers are dyed using disperse dyes in a weakly acidic region at high temperatures and pressures of 110 to 140° C. using dyed objects that have undergone a sufficient scouring process. At this time, a dispersion leveling agent is added to the dyeing bath in order to eliminate uneven dyeing caused by insufficient dispersion of the disperse dye, and to promote the slow dyeing effect or dye migration effect and improve the leveling property. Added.
この分散均染剤としては、例えば、ナフタレンスルホン
酸塩のホルムアルデヒド縮合物、ポリオキシアルキレン
アルキルアリールエーテル、ポリオキシアルキレンアル
キルエステル、ポリオキシアルキレンアルキルアリール
エーテル硫酸エステル塩、ポリオキシアルキレンアリー
ルエーテル硫酸エステル塩などが使用されている。Examples of the dispersing and leveling agent include formaldehyde condensates of naphthalene sulfonates, polyoxyalkylene alkylaryl ethers, polyoxyalkylene alkyl esters, polyoxyalkylene alkylaryl ether sulfate salts, and polyoxyalkylene aryl ether sulfate salts. etc. are used.
しかし、最近では、精練が不十分であったり、全く精練
されていないまま被染色物が染色工程に入る場合が多い
。この場合に、前述した通常の染色方法を用いると、不
均染などのトラブルを発生し易い。このトラブルをある
程度解消するために、アルカリ染色と呼ばれる染色方法
がとられることが多い。ここで言うアルカリ染色とは、
染色浴中にアルカリ剤を添加することによって染色をア
ルカリ性領域で行う方法で、染浴をアルカリ性にするこ
とで、ある程度の精練効果を生むというものであるが、
その効果は完全なものではない。However, recently, it is common for objects to be dyed to enter the dyeing process with insufficient scouring or no scouring at all. In this case, if the above-mentioned normal dyeing method is used, troubles such as uneven dyeing are likely to occur. In order to solve this problem to some extent, a dyeing method called alkaline dyeing is often used. What is the alkali dyeing mentioned here?
It is a method of dyeing in an alkaline region by adding an alkaline agent to the dye bath, and by making the dye bath alkaline, it produces a certain degree of scouring effect.
The effect is not complete.
被染色物の精練が十分に威されている場合には前述した
従来の染色法で問題ないが、精練が不十分であったり、
全く精練されていない場合には従来の方法は適当でない
。その理由は、以下のようである。If the object to be dyed has been sufficiently refined, there is no problem with the conventional dyeing method described above, but if the object is not refined enough,
In cases where there is no refining at all, conventional methods are not suitable. The reason is as follows.
最近の染色加工においては、多様な要求に対応すべく多
品種小ロツト化の傾向にあり、加工コストが上昇ぎみで
ある。そこで、加工コスト低減のため加工プロセスの短
縮化或は簡略化がなされつつある。特に、生産性の向上
および省エネルギーを考えた場合、精練工程及び洗浄工
程を簡略化もしくは省略する手段がとられてきている。In the recent dyeing process, there is a trend toward small lots of a wide variety of products in order to meet various demands, and processing costs are on the rise. Therefore, the machining process is being shortened or simplified in order to reduce the machining cost. Particularly, in consideration of improving productivity and saving energy, measures have been taken to simplify or omit the scouring process and the cleaning process.
従って、精練工程で除去されているはずのアクリル糊剤
、澱粉、ポリビニルアルコール、プロセス油剤等が、被
染色物に残存したまま染色工程に入ることになり、この
ことが原因となって不均染になることが多く大きな問題
となってきている。Therefore, the acrylic paste, starch, polyvinyl alcohol, process oil, etc. that should have been removed during the scouring process remain on the dyed object during the dyeing process, causing uneven dyeing. This is becoming a major problem.
そこで、最近はこのトラブルを低減する目的でアルカリ
染色が用いられてきてはいるが、単にアルカリ剤を加え
て染色するというこの方法では効果が薄く、さらに精練
効果を高める染色助剤への要望が高い。Therefore, recently, alkaline dyeing has been used to reduce this problem, but this method of simply adding an alkaline agent and dyeing has little effect, and there is a demand for dyeing aids that further enhance the scouring effect. expensive.
また、通常の分散染料による染色の場合には、染色工程
の後、未固着の染料を取り除き、高堅牢染色物を得るた
めに、還元洗浄工程が必要不可欠となる。しかし、この
工程も、前述した加工コストの問題から、望ましくは省
略したい工程である。Further, in the case of dyeing with ordinary disperse dyes, a reduction washing step is essential after the dyeing step in order to remove unfixed dye and obtain a highly fast dyed product. However, this step is also a step that is desirably omitted due to the problem of processing cost mentioned above.
更に、ポリエステル系繊維を分散染料で染色する場合、
高温高圧の条件下では、ポリエステルオリゴマーやポリ
エステルオリゴマーと染色浴中に含まれる金属イオンと
が結合したスケールが発生する。これらのオリゴマーや
スケールは、被染色物に付着して不均染の原因となる。Furthermore, when dyeing polyester fibers with disperse dyes,
Under conditions of high temperature and high pressure, scale is generated in which polyester oligomers or polyester oligomers are combined with metal ions contained in the dye bath. These oligomers and scales adhere to objects to be dyed and cause uneven dyeing.
そこで、オリゴマーやスケールが発生しても、それを染
色浴中に分散させて、繊維や缶体に付着させないことも
重要である。Therefore, even if oligomers and scales are generated, it is important to disperse them in the dye bath so that they do not adhere to the fibers or the can body.
本発明者は、これらの問題点を解決すべく鋭意研究を重
ねた結果、染色浴中に次のような化合物を染色助剤とし
て添加することにより、高品位な染色物を得るに至った
。As a result of extensive research in order to solve these problems, the present inventors were able to obtain high-quality dyed products by adding the following compounds as dyeing aids to the dye bath.
即ち、本発明は、燐酸系有機化合物を主成分とするポリ
エステル繊維材料用精練染色助剤を提供するものである
。また、本発明を実施する際には、精練均染剤成分と共

Furthermore, when carrying out the present invention, it is recommended to simultaneously add an alkaline agent component to enhance the scouring effect and a dispersant component to prevent dye speckling to the dyeing bath together with the scouring leveling agent component. preferable.

By using a surfactant in combination, the sizing agent that has fallen off into the dye bath is dispersed, so that it is possible to prevent the sizing agent from coagulating and re-adhering to the object to be dyed. Examples of surfactants used as the dispersing and leveling agent include formaldehyde condensates of naphthalene sulfonates, polyoxyalkylene alkylaryl ethers, polyoxyalkylene alkyl esters, polyoxyalkylene alkylaryl ether sulfate salts, and Examples include oxyalkylene aryl ether sulfate salts.
本発明の助剤は、通常のポリエステル系繊維の浸染操作

い。The auxiliary agent of the present invention can be applied to all conventional dyeing operations for polyester fibers. The dyeing temperature is preferably 90 to 135°C; if it is lower than this, the desired scouring property will be insufficient, and if it is higher than this, there is a risk that the dye will be decomposed by alkali. Further, the bath ratio is preferably 1:5 or more.

止にも効果があると考えられる。When dyeing poorly refined or unrefined polyester fiber materials, in order to obtain evenly dyed and high-quality dyed products, the first step is to remove acrylic glue and starch, which hinder uniform dyeing. It is important to remove polyvinyl alcohol, process oil, oligomers, etc. from the object to be dyed at least in the first half of the dyeing process. Furthermore, it is necessary to prevent the sludge discharged into the dyeing bath from re-adhering to the object to be dyed due to the scouring effect. The phosphoric acid-based organic compounds typified by phytic acid, which are adopted as the scouring and leveling agent components of the present invention, are effective in promoting the shedding of acrylic pastes etc. due to their excellent chelating ability, and are effective for promoting the removal of acrylic pastes etc. It is also thought to be effective in preventing re-adhesion.

色物への再付着防止にも有効であると考えられる。The effect is stronger in alkaline regions, so an alkaline agent is added. Furthermore, if desired, a surfactant employed as a dispersant component not only provides dye dispersion, slow dyeing effect, and dye migration effect, but is also effective in preventing scale from re-adhering to the dyed object. it is conceivable that.

る。Furthermore, the scouring effect is exerted during the dyeing process.
Makes it very easy to remove unfixed dyes from dyed articles. Normally, after dyeing polyester fibers with disperse dyes, reduction washing is performed to remove unfixed dyes from the dyed material and obtain dyed products with high fastness. If you do, you can achieve your goal with a simple hot water wash.
このような作用により、本発明の染色助剤を使用して得
られた染色物は、均染性および風合に優れるばかりでな
く、還元洗浄を省略しても高堅牢度を有する。Due to this effect, the dyed product obtained using the dyeing aid of the present invention not only has excellent level dyeing properties and texture, but also has high fastness even if reduction washing is omitted.
