Effect of Different Mordants on Cotton Cloth Dyed with Aspergillus and Penicillium Dyes

Abstract

Natural dyes are an important alternative to potentially harmful synthetic dyes. This research was conducted using three kinds of Aspergillus dyes and six kinds of Penicillium dyes. In this study, Aspergillus and Penicillium were grown in mineral salts glucose medium. Premordanting technique was followed using different mordants, namely alum, CaCO3, CuSO4 5H2O, FeSO4 7H2O, K2Cr2O7 and MnSO4 H2O on cotton cloth. The colour of filtrate and range of colours developed on dyed materials were measured by RHS colour chart. The results indicated that the colour of dyed cloth was influenced by the addition of mordants, and different shades were obtained from the same dye filtrate using different mordants. FeSO4 7H2O was found as the most influential mordant. The present study shows a new source of fungal dyes, which can be used as an alternative for dyeing cloth.   Â

Combination of culture and dyeing conditions on cloth color dyed with mixed fungi dyes

“…5,6,7,& 8). The results are in accordance with our previous study (Suciatmih and Hidayat, 2017) on cotton cloth dyed with the dyes from each fungus such as Aspergillus sp. strain 1 and 2; and Penicillium sp strain 1, 3a, 3b, and 720 combined with different mordants (alum, CaCO3, and FeSO4.7H2O and control).…”

“…The characteristics of color shadings on the cloth depend on the mordants type used during the dyeing proc ess (Suciatmih and Hidayat, 2017). The different C and N sources, and culture conditions, such as different incubation temperatures and pH with different mordants generated various colors on the cloth (Tab.…”

“…Different shades and tones might be obtained from a single dye source by application of the pH value of its bath (Wang et al, 2014;Ren et al, 2016;Suciatmih and Yuliar, 2018) and mordant (Sangeetha et al, 2015;Suciatmih and Hidayat, 2017;Suciatmih and Yuliar, 2018). The effect of the dyeing pH can be attributed to the correlation between the pigment structure and cotton cloth.…”

The Evaluation of the Combination of Additives and Fungal Dyes to Produce Color for Textile Painting

“…Various dyes from fungi were informed, including yellow dyes by Aspergillus sydowii (CML 2967), two isolates of A. aureolatus (CML 2964 and E.4.1), and two isolates of A. keveii (CML 2964 and E.4.1) (Nirlane da Costa Souza et al 2016); greyed-orange dyes by Asper-gillus terreus and Aspergillus sp. strain 2 (Suciatmih & Hidayat 2017); greyed-purple dyes by Paecilomyces lilacinus (Thom) Samson and Paecilomyces sp. strain 542 (Suciatmih & Yuliar 2018); and red dyes by Aspergillus sp.…”

“…Single dyes source added with different mordant types produced different colors and tones on the dyed cloth (Sangeetha et el. 2015;Suciatmih & Hidayat 2017;Suciatmih et al 2019;Suciatmih 2020). Rohandi and Listian (2015) stated that the paint quality was determined by selecting components, such as appropriate adhesives and additives.…”
