Assessment of the Dyeing Properties of the Pigments Produced by Talaromyces spp.

Abstract

The high production yields of pigments by Talaromyces spp. and their high thermal stability have implied that industrial application interests may emerge in the food and textile industries, as they both involve subjecting the colourants to high temperatures. The present study aimed to assess the potential application of the pigments produced by Talaromyces spp. in the textile area by studying their dyeing properties. Dyeing studies were performed on wool. The dyeing process consisted of three stages: scouring, mordanting, and dyeing. Two different mordants (alum, A; ferric chloride, F) were tested at different concentrations on fabric weight (A: 5, 10, 15%; F: 10, 20, 30%). The mordanting process had a significant effect on the final colour of the dyed fabrics obtained. The values of dyeing rate constant (k), half-time of dyeing (t1/2), and sorption kinetics behaviour were evaluated and discussed. The obtained results showed that pigments produced by Talaromyces spp. could serve as a source for the natural dyeing of wool textiles.

Fungal Pigments and Their Prospects in Different Industries

“…DgCr22.1b Talaroxanthone (yellow) [107] Talaromyces siamensis, Talaromyces sp. Uncharacterized (red) [71,108] Talaromyces sp. N-threonine rubropunctamine (red) [72] Hamigera avellanea (Formerly Known as Talaromyces avellaneus)…”

“…The literature reveals that only a handful of studies have investigated the application of fungal pigments in the textile industry, especially for dyeing different types of fabrics, such as cotton, silk, and wool. Various studies on the dyeing potential of pigments of different species of fungal genera (Monascus, Fusarium, Aspergillus, Penicillium, Talaromyces, Trichoderma, Alternaria, Curvularia, Chlorociboria, Scytalidium, Cordyceps, Acrostalagmus, Bisporomyces, Cunninghamella, Thermomyces, and Phymatotrichum) for different types of fabrics such as wool, cotton yarn, silk, polyester, and nylon have been reported [37,42,47,106,108,124,195,196,[208][209][210][211]. Studies on the dyeing potential of pigments from wood spalting fungi (red pigment from S. cuboideum, yellow pigment from S. ganodermophthorum, and green pigment C. aeruginosa) have shown the possible use of these pigments for deying bleached cotton, spun polyacrylic, spun polyamide (nylon 6.6), worsted wool, spun polyester (Dacron 54), and garment fabrics, because of their high stability and good colorfastness to washing [37,212].…”

A Note on the Dyeing of Wool Fabrics Using Natural Dyes Extracted from Rotten Wood-Inhabiting Fungi

“…Liquid cultures of pigments and dyes producing fungi, including Talaromyces spp. have been used to dye fabrics directly after the filtration of mycelia and spores [14,28,29]. Color obtained by this method of application highly depends on the yield of the colored metabolites in the media.…”

“…Color is an important form of expression in inheriting social civilization by integrating art and reality and expressing complex emotions of human beings [1]. Human fascination and pursuit of color has never stopped.…”
