An environmentally friendly approach to textile dyeing with biomaterials

<p style="text-align:justify;line-height:115%"><span lang="EN-US">In recent years, intensive research has beenconducted on natural dyes, which have been rediscovered as a result of thesearch for sustainable, environmentally friendly dyes that do not harm theenvironment or humans in the coloring of textile materials. In this study,rosemary (<i>Salvia rosmarinus</i>) was usedas a natural dye source for the dyeing of woolen fabrics. Rosemary has aneedle-like structure and is generally used for medicinal purposes, as a spice,and as an ornamental plant. The rosemary plant used as the dye was dried andground. The dyeing process was carried out at 95°C for 1 hour using FeSO₄ andCuSO₄ metal salts, or a combination of these, as mordants. After dyeing, a"warm wash-soap wash-warm wash-rinse" process was applied, and thenit was dried at room temperature. Khaki, brown, and beige hues were obtained.The CIE <i>L*a*b*</i> color values ​​and <i>K/S</i> values ​​of the colored samples weredetermined using Konica Minolta spectrophotometry. In addition, the washing andrubbing fastness values ​​of the dyed samples were tested, and a score of 4-5was obtained. As a result, acceptable color tones and fastness tests wereachieved for the dyed samples.<o:p></o:p></span>
