Extraction and Concentration Comparison of Dyeing Behavior of Orange dye on Lyocell Fabric

Abstract

Natural dyes are widely considered for their environmental properties and ease of use. In this study, Lyocell fabrics were dyed with natural dyes, extracted by peeling oranges, and evaluated comparatively based on color efficiency (K/S), CIE L * a * b * values, and fastness. Re-infer minerals using metal (II) sulfates and copper sulfate (II). In order to extract the dye, the standard technique of water extraction is used. The dyeing effect of Lyocell fabric was checked at 2% and 4% by the method of pre-immersion and post-immersion. The study found that this seasoning affects the efficiency of the color of the fabric dyed with orange peel. All dyed samples showed better, better color efficiency (K/S: 4.57) at 4% concentration levels during the post- mordanting processing (K/S: 4.57), color fastness of washing, light, and friction, and sweat. In general, the post- mordanting method at the 4% concentration level has a significant effect on color efficiency and color fastness characteristics.
