These synthetic dyes produce skin irritation and toxicity. This study used <em><i>Lawsonia Inermis<\/i><\/em>, commonly called heena leaves,to extract a natural colourant used as a coloring agent for ladies&#8217; hands and feet during festivals and ceremonies. Currently, Metallic mordants such as copper sulphate (CuSO<sub>4<\/sub>), ferrous sulphate (FeSO<sub>4<\/sub>), and ferric chloride (FeCl<sub>3<\/sub>) are used to change the hue of natural dyes and applied on multi-fiber fabric by the exhaust method. Multi-fiber fabric is a special type made from a blend of unlike fibers such as cotton, cellulose acetate, polyacrylonitrile,\u00a0polyamide, polyester, and wool.\u00a0This fiber can be used in various applications as per the industry&#8217;s requirements. Lawson dye was extracted from henna leaves in aqueous medium at room temperature, 30\u00b11<sup>o<\/sup>C. However, the color fastness, color strength (K\/S),\u00a0washing fastness,\u00a0% Reflectance,and colour space (CIEL*a*b*) were observed in acidic and basic media. In colour space of the sample, L<sup>*<\/sup>\u00a0is used to measure light fastness, and a<sup>*<\/sup>,b<sup>*<\/sup>\u00a0are used to measure green-red, blue-red color components, respectively. Colour strength (K\/S) was determined through a colorimeter. The CIE L<sup>*<\/sup>, a<sup>*<\/sup>,b<sup>*<\/sup>\u00a0properties identified in two different lights, such as D65\/10<sup>o<\/sup>, TL84-10. During this work, it was observed that after washing, the value of \u00a0\u00a0L<sup>* <\/sup>and b<sup>*<\/sup>\u00a0increases, and the value of a<sup>*<\/sup>\u00a0decreases, indicating that samples become lighter and yellower. This result revealed that the color strength and fastness properties are higher in alkaline than in acidic medium. Cellulose acetate, cotton, and polyamide show good resistance to light.<\/p><\/div><div class=\"item abstract\"><h3 class=\"label\">How to Cite this paper?<\/h3><div class=\"csl-entry\"><p><strong>APA-Style<\/strong><br \/>A.
