“…Cotton fabric has a negative charge as well. Since the same charges repel each other, it was apparent that cotton fabric with current conditions would not show sufficient color strength compared to the wool fabric which is positively charged and therefore much more prone to fiber/mordant/dye crosslinking [ 42 , 43 , 44 , 45 ].…”

“…A peak at 1233 cm −1 is assigned to CH 2 and CH 3 bending. Dyed samples showed a little bit lower intensity of peaks characteristic for amide-I and amide-II compared to untreated wool indicating the involvement of amine functional groups within the wool, alum and dye molecules [ 45 ]. Untreated wool shows a peak at 1515 cm −1 (peak characteristic for amide-II) which closely corresponds to the peak at 1513 cm −1 of investigated dye solution.…”

Natural Dyeing of Cellulose and Protein Fibers with the Flower Extract of Spartium junceum L. Plant

et al. 2021

In this study, the natural dye was extracted from Spartium junceum L. (SJL) flowers and applied on cellulose (cotton) and protein (wool) fabric. Fabrics were pre-mordant with alum prior to the dyeing process. Considering the global requirements on zero waste and green policy, the dyeing process was intended to be as much as possible environmentally friendly but still effective. Therefore, mordant concentration was optimized due to the reduction of the negative impact. The efficiency of the dyeing process was investigated by examination of fabrics’ color characteristics and colorfastness to washing properties. In this paper, we have proved that the extracted dye from Spartium junceum L. is an acidic dye (mordant dye) which is more applicable for the treatment of wool fabrics. In this paper, it was proved that phytochemicals responsible for coloring are part of the flavonoids group. The UV absorption spectra of extracted dye show 4 bands in the region of λmax 224, 268, 308 and 346 nm which are ascribed to bands characteristic for flavonoids. Wool fabric pre-mordant with 3% alum and dyed shows great chromatic (C*) properties where C* value is in a range from 47.76 for unwashed samples to 47.50 for samples after 5 washing cycles and color hue (h°) is in a range 82.13 for unwashed samples to 81.52 for samples after 5 washing cycles. The best result regarding the colorfastness properties is shown by the wool sample treated with 3% alum after 5 washing cycles (total difference in color (Delta E*) = 0.87). These results confirm that metal (Al) from alum mordant make strong chemical bonds with wool substrate and dye since Delta E* values decrease in comparison to Delta E* values of the cotton samples treated the same way. The results revealed it is possible to reduce the concentration of mordant up to 3% and obtain satisfactory results regarding the colorfastness. Nevertheless, future research will go in the direction of replacing synthetic mordant with a more environmentally friendly one.

“…Physical properties of treated and untreated cotton fabrics such as absorbency, fabric stiffness, air permeability, and strength were analyzed. To evaluate the laundering effect of stinging nettle leaf finished fabric, samples were subjected to laundry with 5,10,15,20,25,30,35, and 40 washing cycles using standard AATCC test method 61, and bacterial count of treated samples was tested. e results showed gradual decrease in antibacterial property, with a 100 to 44% reduction in the bacterial count for Staphylococcus aureus and a 100 to 30% reduction in the bacterial count for Escherichia coli.…”

Natural organic fibers such as cotton, linen, and wool are readily attacked by microorganisms. Microbial growth on a textile fabric causes loss of strength and elongation, discoloration, and changes in appearance. The antibacterial finishing agents extracted from nettle plant leaf have been used to impart finish to the cotton fabric by using the Pad-Dry-Cure application method. The antibacterial activity of the finish was assessed quantitatively using the AATCC 100:2004 test method, and the antibacterial activity against Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria was measured. There was a 100 to 99.75 percent reduction in the count of test bacteria. Physical properties of treated and untreated cotton fabrics such as absorbency, fabric stiffness, air permeability, and strength were analyzed. To evaluate the laundering effect of stinging nettle leaf finished fabric, samples were subjected to laundry with 5, 10, 15, 20, 25, 30, 35, and 40 washing cycles using standard AATCC test method 61, and bacterial count of treated samples was tested. The results showed gradual decrease in antibacterial property, with a 100 to 44% reduction in the bacterial count for Staphylococcus aureus and a 100 to 30% reduction in the bacterial count for Escherichia coli. The results of this investigation suggested that nettle leaf, a low-cost abundant plant in Ethiopia, can be used for antibacterial activity in woven cotton fabric.

“…No caso dos ensaios executados á úmido, as notas variaram entre 3, 3-4, 4 e 4-5, consideradas de "boas à ótimas". Segundo Singh et al (2019), as notas de fricção à úmido podem ser inferiores em relação ao ensaio à seco, pois o corante presente na superfície do tecido úmido é responsável pela baixa resistência à fricção, causando manchas em tecidos brancos. Além disso, ainda segundo os autores, a baixa resistência também pode ser um indicativo de fraca interação corante-fibra.…”

“…Existem diversas pesquisas que demonstram atividade antibacteriana de tecidos tingidos com corantes naturais (SINGH et al, 2019;LEE et al, 2017;KIM, 2009;TELI, 2014;SILVA et al, 2018) e outras que apontam a atividade do extrato de cascas de romã frente à microrganismos diversos, como ao Staphylococcus aureus (TRINDADE;JUIZ, 2009;PAGLIARULO et al, 2016;AL-ZOREKY, 2009;MACHADO et al, 2003;KHARCHOUFI et al, 2018). Com o intuito de verificar se a ausência de atividade das amostras tingidas foi devido a inconstâncias oriundas do processo de tingimento, o extrato aquoso liofilizado das cascas de romã também foi avaliado.…”
