Dyeing, fastness and antimicrobial properties of woolen yarns dyed with gallnut (Quercus infectoria Oliv.) extract

Ecological dyeing of Woolen yarn with Adhatoda vasica natural dye in the presence of biomordants as an alternative copartner to metal mordants

“…Recently discovered properties of natural dyes such as insect repellent [1], deodorizing [2], flame retardant [3], UV protection [4], fluorescence [5,6], and antimicrobial activity [7][8][9], besides being biocompatible, biodegradable, renewable, and nontoxic have revolutionized all industrial sectors especially textile industry for producing more appealing and highly functional value-added textiles [10,11]. This is a result of ecological concerns related with the use of 118 of the azo and benzidine synthetic dyes with 24 carcinogenic aromatic amines as their primary photolytic degradation products, which have motivated researchers all over the globe to explore new eco-friendly substitutes for minimizing their negative environmental impacts [12].…”

Dyeing studies and fastness properties of brown naphtoquinone colorant extracted from Juglans regia L on natural protein fiber using different metal salt mordants

“…In response to that, many European countries have imposed ban on their use (Ali et al 2013;Jothi 2008;Bechtold et al 2003). Enhanced environmental awareness has motivated researchers to reintroduce natural colorants from natural sources like plants (stem, bark, leaves, roots, and flowers), animals, and minerals (Samanta and Agarwal 2009;Shahid et al 2012;Shahid et al 2013). In addition to their biodegradability and compatibility with the environment, natural colorants have been recently discovered to exhibit other functional properties, such as antimicrobial activity Yusuf et al 2015), insect repellent (Ali et al 2013), fluorescence (Rather et al 2015), UV protection (Grifoni et al 2009;Sun and Tang 2011), and deodorizing (Lee et al 2009).…”

Extraction of natural dyes from Curcuma longa, Trigonella foenum graecum and Nerium oleander, plants and their application in antimicrobial fabric

“…India, due to its rich biodiversity and varied climatic zones, is a source of a wide range of natural dyes. Although natural dyes have meritsobtained from renewable resources, non-hazardous, eco-friendly (Mariselvam et al, 2012a,b,b;Hashem et al, 2009;Shahid et al, 2012;Khan et al, 2011;Yusuf et al, 2012;Moiz et al, 2010;Lawhavinit et al, 2010), etc. Their availability is not widespread because of very few organized manufactures, non-standardization of raw material and manufacturing process, and complexity of process involved in application of natural dyes (Prusty et al, 2010;Singh et al, 2005;Ramya et al, 2011;Singh and Jain, 2012).…”
