Coloration of flax woven fabrics using Taxus baccata heartwood‐mediated nanosilver

Abstract

Ecological nanosilver-based colours were biosynthesised from the heartwood of European yew (Taxus baccata) trees for the dyeing of flax woven fabrics through the implementation of in situ synthesis protocols. The produced lighter brown yellow to darker brown-yellow coloured nanosilver particles on flax woven fabrics were characterised in terms of morphological observations, metallic compositions, elemental mapping, chemical interactions, the presence of silver nanoparticle (AgNP) concentrations and colour characteristics with associated performances. The presence of AgNPs was clearly observed by morphological studies of the coloured substrates. Quantitative analysis of the products also confirmed the significant presence of AgNPs. The results demonstrate that the uniform dispersions and strong attachments of AgNPs in cellulosic flax woven fabrics are due to surface plasmon resonance characteristics. The incorporation of different concentrations of metallic AgNPs plays a significant role in producing versatile colour appearances on flax woven textiles with improved colour durability. The overall results offer new routes for sustainable structural colourants in the industrial dyeing of cellulosic materials.

Green synthesis of nanosilver using Fomes fomentarius mushroom extract over aramid fabrics with improved coloration effects

“…The circumstances reported above are also in line with some other studies. 33,36,48,49 However, this study provides concrete confirmation regarding the successful synthesis of metallic silver over aramid surfaces. ) and morphological (A2, B2, C2, D2) photographs of the C@A, M@Ag1, M@Ag2, and M@Ag3 specimens, respectively.…”

“…The perceived results are also in agreement with the deposited AgNPs over nylon, cotton, flax, aramid, and glass woven fabrics too, which were reported previously. 33,35,36,41,42 The XRF analysis displays the concrete quantification values of the metallic silver present over the aramid fabrics.…”

“…The reported results here also agree with some previous studies. 36,53,54 Moreover, the significance of all of the colorimetric data was also tested statistically in terms of R 2 values and found to be significant. R 2 values were tested in terms of colorimetric values against nanosilver loading.…”

“…The fastness properties of the colored materials were evaluated according to our previous studies. 32,36 In brief, the washing fastness properties of the colored aramid fabrics were tested as per ISO105C06:1994 standard protocols, 37 whereas rubbing fastness properties were investigated using the ISO105‒X12:2003 standard. 38,39 Distilled water was used for conducting the fastness property investigations.…”

Enhancing mechanical and antibacterial performances of organic cotton materials with greenly synthesized colored silver nanoparticles

“…In this regards, different attempts are taken by the scientists to nourish the sustainable coloration sector through employing different naturally derived materials like as flowers, barks, heartwoods, leaves, roots and so on to synthesize AgNPs (Hasan et al. , 2021c, d, e, f). Besides plant-based stabilizing agents, chitosan could be another excellent example of natural polysaccharides, i.e.…”
