In this study, a series of disazo-3-methyl-1H-pyrazole-5-on derivatives (5a-e) ,which can also be found in previous studies, has been re-synthesized. Their structures were verified with FT-IR results and the melting points. Preliminary dyeing experiments with synthesized dyes had been applied to multifiber fabric. All dyeing experiments to Nylon 6,6 (PA6.6) and Polyester (PES) fabric were made in the laboratory and dyeing properties of textile materials used were investigated. In the end, it was found that the synthesized dyes could be applied to fabric, which is made of PA6.6 and PES.Fastnesses were examined according to ISO standards. The following were the applied fastnesses: water, perspiration, washing at 40o C and 60o C, in pool water with 20 ppm, and wet/dry rubbing. All results were compared with closest commercial dyes (T1 and T2). As the results of the fastness tests have been investigated, it can be summarized that staining values of synthesized 5a, 5b, 5c, 5d and 5e dyes, especially for nylon, acetate and PES fibers, are better than T1 and T2, whereas wet and dry rubbing values are worse being between 0.5 and 3s. Chlorined water fastness and color changes of all dyes are equal to each other.

Öz

Bu çalışmada, literatürde bulunan bir seri disazo-3-metil-1H-pirazol-5-on türevleri (5a-e) yeniden sentezlenmiştir. Yapıları FT-IR ve erime noktası ile doğrulanmıştır. Sentezlenen boyarmaddeler ile multifibre kumaş üzerine boyama ön denemeleri yapılmıştır. Boyarmaddelerin naylon 6,6 ve poliesteri boyayabildiği görülmüştür. Naylon 6,6 ve poliester kumaş üzerine laboratuar ortamında boyamalar yapılmış ve bu tekstil malzemelerini boyama özellikleri incelenmiştir. ISO standartlarına göre, suya karşı, asidik ve bazik tere karşı, 40 o C ve o C yıkamaya karşı, 20 ppm klorlu suya karşı, yaş ve kuru sürtmeye karşı haslıkları incelenmiştir. Bulunan haslık sonuçları bunlara yakın renk veren ticari boyalar (T1 ve T2) ile kıyaslanmıştır. Yapılan haslık testlerinin sonuçları incelendiğinde, sentezlenen 5a, 5b, 5c, 5d ve 5e boyarmaddelerinin özellikle naylon, asetat ve PES elyaflarını kirletme değerleri T1 ve T2’ ye nazaran daha iyi, buna karşın yaş ve kuru sürtme değerlerinin yarım ile 3 puan arası kötü olduğu şeklinde özetlenebilir. Tüm boyaların klorlu su haslıkları ve renk değişimleri birbirine denktir.
