“…From Table is can be concluded that the hue of all samples is in the red–yellow sector of the colour circle, which is in agreement with the positive a and b values and is visually confirmed. The K / S values of the digitally printed cotton samples are satisfactory and higher than those obtained by exhaustion application of natural dyes on cotton . This can be explained by the fact that natural dyes applied from an aqueous medium generally show low affinity and thus low exhaustion, whereas natural dyes applied by digital printing are deposited as required locally on the surface of the substrate through the printing nozzle, allowing more dye on the surface of the samples.…”

Four natural dyes, annatto, cutch, pomegranate fruit rind, and golden dock, were used as colorants for the preparation of water-based ink-jet inks for digital textile printing. The physical and rheological properties (pH, conductivity, surface tension, and viscosity) of the inks were measured over a period of 90 days for the evaluation of ink stability and suitability for ink-jet printing. The inks were found to be suitable and were used for the digital printing of cotton fabrics. The prints were subjected to wash, light, and rub fastness tests and colour measurements. Colour consistency and fastness results, especially after fixation, are comparable with those of synthetic dyes, which paves the way for the production of environmentally friendly ink-jet inks using natural dyes for the digital printing of cotton through the formulation of suitable printing techniques.

Metal mordanting in dyeing with natural colourants

2016

Metal mordanting, or the application of metal salts, is a common method of improving the light fastness in dyeing with natural colourants. This review presents the results from a survey of the literature on metal mordanting to assess what levels of correlation exist between mordant‐induced effects (changes in colour and colour depth) and the changes in light fastness, what is known about the mechanisms of mordant‐induced improvements of light fastness, and how the salt levels used in coloration processes compare with the limits on metal levels in wastewater and on the dyed substrates. No strong interrelationships are found between the mordant‐induced effects and light fastness improvements. Knowledge about mechanisms of mordant effect on light fastness appears, in large part, to be derived from empirical correlations. However, as light fastness is affected by a multitude of factors, the correlations do not always hold true. It is found that residual metal contents in spent dye/mordanting liquors are generally not reported. However, with rough calculations, it is estimated that, with even the lowest reported salt concentrations, the metal contents in spent liquors exceed environmental release limits. The metal contents on dyed substrates are also not generally reported, but similar estimations show that the contents of heavy metal on dyed substrates (when copper and chromium salts are used as mordants) also exceed limits. On the basis of these observations, the authors make suggestions for elements to be included in investigations on furthering the use of natural colourants in textile dyeing.

“…Boyamalar; mordansız, ön-mordanlama, birlikte mordanlama ve son-mordanlama olmak üzere dört yöntem kullanarak gerçekleştirildi. Doğal boyamada yaygın olarak kullanılan mordanlar şap (AlK(SO4)2·12H2O), potasyum dikromat (K2Cr2O7), kalay (II) klorür (SnCl2·2H2O), demir sülfat (FeSO4·7H2O) ve bakır sülfat (CuSO4·5H2O) [22] olmasına rağmen, bu çalışmada, metalik mordanlar arasında en zararsız olarak kabul edilen şap ve demir sülfat mordanları kullanıldı [23,24]. Gölgede kurutulmuş kızılağaç yaprakları, saf su (1:20) ortamında soxhlet cihazı kullanılarak renksizliğe kadar ekstrakte edildi ve etken boyarmaddenin su fazına geçmesi sağlandı.…”

ÖZETBu çalışmada, doğal boyamacılık için sürekli bir kaynak oluşturulması ve ülke ekonomisine önemli ölçüde katkı sağlanması amacıyla kızılağaç yapraklarının tekstil sektöründe doğal boyarmadde kaynağı olarak kullanılabilirliği araştırılmıştır. Bu bağlamda, yün ve pamuklu kumaşlar FeSO4 ve AlK(SO4)2 mordanları eşliğinde ön, birlikte ve son mordanlama işlemlerine tabi tutuldu. Her kumaş türü için 2 farklı pH değerinde çalışıldı. Boyanan materyallerin renk analizleri yapılarak yıkama, sürtme ve ışık haslıkları bakımından değerlendirildi. Yapılan analizler ve test sonuçlarına göre pamuklu kumaşın yün kumaşa göre daha iyi boyandığı ve son mordanlama yönteminin daha iyi sonuç verdiği tespit edilmiştir. Pamuklu kumaşlarda, FeSO4 mordanı ile özellikle bazik ortamda yapılan boyamalarda daha yüksek renk şiddeti elde edilmiştir.Anahtar Kelimeler: Kızılağaç yaprağı, Boyama, Mordan, Haslık EVALUATION OF COMMON ALDER LEAVES AS DYESTUFF SOURCE IN TEXTILE INDUSTRY ABSTRACTIn this study, the usage of common alder leaves as natural source of dyestuff in the textile industry was investigated for the purpose of creation of a constant source of natural dyeing and it provides a significant contribution to the country's economy. In this concept, wool and cotton fibers were subjected to pre-mordanting, meta-mordanting and post-mordanting processes in the presence of FeSO4 and AlK(SO4)2 mordants. The studies were carried out using 2 different pH values for each type of fibers. Color analyses of the dyed materials were done and the results were evaluated in terms of wash, rubbing and light fastness values. According to the test results, it is detected that cotton fabrics exhibited better dyeing potential than wool fabrics and highest color strength values were obtained using post-mordanting method. For cotton fibers, high color strength values were obtained in the presence of FeSO4 mordant, especially in alkali medium.
