Determination of the Dyeing Potential of Mint and Sage Crops Wastes on Wool and Cotton Fibers

ABSTRACT

In the present study, dyeing potential of waste water from distillation process was investigated for fresh and dried herbs of Menthaspicata (MS), Menthapiperita (MP), and Salvia officinalis (SO) species. Meta-mordanting method was used in the dyeing of wool and cotton fabrics in the presence of FeSO₄·7H₂O (iron) and AlK(SO₄)₂·12H₂O (alum) mordants. The color of each dyed material was investigated in terms of the CIELab (L*, a*, b*, C, and h°) and K/S values. The surfaces of the samples were observed using a scanning electron microscope. It was observed that the color strength of fresh and dried plant is depended on the plant species, mordant, and fabric type. Best color intensity (K/S = 16.68) was obtained with iron mordant using fresh SO on cotton fabric. For wool fabric, the highest color strength (K/S = 9.62) was obtained with fresh SO in the presence of alum mordant. Presence of metal mordant for natural dyeing process of cotton with MS, MP, and SO extract has shown remarkable improvement in terms of dye adherence and fastness properties thus metal mordanting could be suitable alternative dyeing method for ecofriendly industrial application.

摘要

本文研究了 洋薄荷 （MS）、 香薄荷 （MP）和 鼠尾草 （SO）等物种的新鲜和干燥植物蒸馏过程的废水染色潜力。在羊毛和棉织物的染色中使用了元媒染法，采用的媒染剂为FeSO₄·7H₂O（铁）和AlK(SO₄)₂·12H₂O（明矾）。每种染色材料的颜色用 CIELab（L*、a*、b*、C和 h°）以及K/S值来进行研究。样品的 表面使用扫描电子显微镜进行观察。根据观察结果，新鲜 和干燥植物的颜色强度取决于植物种类、媒染剂和织物类型 。在棉织物上使用新鲜SO和铁媒染剂可获得最佳颜色强度（K/S = 16.68）。对于羊毛织物，使用新鲜SO和明矾媒染剂可获得最高颜色强度（K/S = 9.62）。研究表明，使用MS、MP和SO提取物以及金属媒染剂对棉布的天然染色过程显著改善了染料的粘附 性和色牢度性能，因此金属媒染可能是适合作为环保工业 应用的替代染色方法。
