Description

【0001】
【発明の属する技術分野】
本発明は、青色系の反応染料組成物及びそれを用いる繊維材料の染色又は捺染法に関する。
【0002】
【従来の技術】
反応染料は従来から繊維材料の染色及び捺染に多用されているが、セルロース系繊維材料を染色及び捺染するための青色反応染料組成物としては、例えば、アントラキノン系反応染料と銅ホルマザン系反応染料からなる混合物(特開平2−99564号公報、特開平1−103668号公報等)や、ビスアゾ系反応染料からなる組成物(特開平1−170663号公報、特開平8−209021号公報)等が知られている。
【0003】
【発明が解決しようとする課題】
反応染料に関しては、(i)ビルドアップ性、均染性、洗浄性が良好で、染色温度依存性、無機塩濃度依存性及び浴比依存性等が小さい、(ii)耐光堅牢度や汗と日光との複合堅牢度、洗濯堅牢度、塩素堅牢度、NOxガス堅牢度など諸堅牢度が優れており、且つ、使用する染料の堅牢度のレベルが揃っていることが好ましい。特に、(i)項の性能については、近年、工場の自動化、染色時間の短縮化による操作の簡略化及び素材の種類や形態の多様化等に伴い、より均染性や洗浄性に優れ、染色の再現性が良好である反応染料が強く望まれている。そして、(ii)項の性能については、染色に使用する染料の堅牢度のレベルが揃っていない場合は、耐光堅牢度や汗日光堅牢度、洗濯堅牢度及び塩素堅牢度の一部や全てにおいて変色が目立つ等の問題が生じる。特に、青色反応染料については、汗日光堅牢度、塩素堅牢度及びNOxガス堅牢度において満足できるものが少なく、これらの堅牢度が良好な染色物や捺染物を得ることは困難である。
一方、反応染料を用いた染色、特に染色濃度が高い染色の場合には、多量の無機中性塩を必要とするが、多量の無機中性塩の添加は、多大な時間と労力を要するので、染色作業の操作性を著しく低下させる。また、多量の無機中性塩の添加は、染色排水への無機中性塩の含量を増大させ、環境問題を考えると好ましくない。従って、少量の無機中性塩の添加で高濃度の染色物が得られる反応染料が要望されている。
更に、近年の環境問題への関心の高まりから、染色排水の着色負荷に対する規則も厳しくなる傾向にあり、固着率が高く、染色排水の着色度の低い反応染料が強く望まれている。
【0004】
【課題を解決するための手段】
本発明者らは、反応染料の染色及び捺染における上記の問題点を解決すべく、鋭意検討した結果、特定の青色系の反応染料組成物がこの目的を達成することを見出して、本発明を完成した。
【0005】
即ち、本発明は、遊離酸の形が、下記式(I)で示される青色反応染料と、遊離酸の形が、下記式(II)で示される青色反応染料とを含有してなる反応染料組成物を提供し、該組成物を用いる繊維材料の染色又は捺染方法をも提供する。

BACKGROUND OF THE INVENTION
The present invention relates to a blue reactive dye composition and a method for dyeing or printing fiber materials using the same.
[0002]
[Prior art]
Reactive dyes have been widely used for dyeing and printing fiber materials. Blue reactive dye compositions for dyeing and printing cellulosic fiber materials include, for example, anthraquinone reactive dyes and copper formazan reactive dyes. Known mixtures (JP-A-2-99564, JP-A-1-103668, etc.), compositions comprising bisazo reactive dyes (JP-A-1-170663, JP-A-8-209021), etc. It has been.
[0003]
[Problems to be solved by the invention]
As for reactive dyes, (i) good build-up property, level dyeing property, cleanability, dyeing temperature dependency, inorganic salt concentration dependency, bath ratio dependency, etc., (ii) light fastness and sweat It is preferable that various fastnesses such as combined fastness with sunlight, wash fastness, chlorine fastness, and NOx gas fastness are excellent, and that the fastness level of the dye to be used is uniform. In particular, with regard to the performance of the item (i), in recent years, with the automation of factories, the simplification of operations by shortening the dyeing time and the diversification of the types and forms of materials, the leveling and cleaning properties are superior. There is a strong demand for reactive dyes that have good reproducibility of dyeing. As for the performance of item (ii), if the fastness level of the dye used for dyeing is not uniform, the light fastness, sweat sunfastness, wash fastness and chlorine fastness are part or all. Problems such as noticeable discoloration occur. In particular, there are few blue reactive dyes that are satisfactory in terms of fastness to sweat sunlight, fastness to chlorine, and fastness to NOx gas, and it is difficult to obtain a dyed product or printed matter having these fastnesses.
On the other hand, in the case of dyeing using reactive dyes, especially dyeing with high dyeing density, a large amount of inorganic neutral salt is required, but the addition of a large amount of inorganic neutral salt requires a great deal of time and labor. The operability of the dyeing work is significantly reduced. Moreover, the addition of a large amount of inorganic neutral salt increases the content of inorganic neutral salt in the dyeing waste water, which is not preferable in view of environmental problems. Therefore, there is a demand for a reactive dye that can obtain a high-density dyed product by adding a small amount of an inorganic neutral salt.
Furthermore, with the recent increase in interest in environmental problems, the rules for the coloring load of dyeing wastewater tend to be strict, and a reactive dye having a high fixation rate and a low coloring degree of dyeing wastewater is strongly desired.
[0004]

When 500 parts of the dye represented by is mixed, a blue reactive dye composition is obtained.
In a dyeing apparatus (bath ratio is 1:10, bath temperature is 80 ° C.) in which 10 g of knitting made of rayon is set, 0.2 g of the composition and 3.0 g of anhydrous sodium sulfate are added, and the knitting is performed at 80 ° C. for 20 minutes. After processing and adding 2.0 g of sodium carbonate, dyeing and washing at this temperature for 60 minutes gives a uniform, blue, light-resistant, sweaty sunlight, chlorine and dyeing fastness to washing. Moreover, reproducibility is good even if the above dyeing is repeated.

After adding 720 parts of the dye represented by formula (100), 100 g of the dye represented by the formula (5) sufficiently mixed with 0.3 g of the composition and 4.0 g of anhydrous sodium sulfate into the bath by a known method The knitted fabric was treated for 20 minutes at this temperature, and 2.0 g of sodium carbonate was put into the bath by a known method. The knitting was then treated for 60 minutes at this temperature, and the dyeing was finished. The resulting dyed product was washed and finished by a conventional method. The obtained dyed product was a uniform blue with no spots. The dyed product obtained had good light resistance, sweat sunlight, chlorine, and fastness to washing. Further, the above dyeing was repeated, and all of the dyeing reproducibility was good.

When 400 parts of the dye represented by the above formula and 600 parts of the dye represented by the formula (5) are sufficiently mixed, an amber-colored dye composition is obtained.
200 parts of this dye composition is dissolved in hot water, cooled to 25 ° C., 1 part of sodium alginate, 10 parts of sodium metanitrobenzenesulfonate and 20 parts of sodium hydrogen carbonate are added, and water is further added to make the total amount. 1000 parts at 25 ° C., using this solution as a padding solution, padding the cotton fabric, drying the fabric for 2 minutes at 120 ° C., and then steaming for 5 minutes at 100 ° C. A dyed product which is amber and has good light resistance, sweat sunlight, chlorine and fastness to washing can be obtained. Even if the above dyeing is repeated, the reproducibility of the dyeing is good.
