Recently, there has been a surge of interest in adopting natural dyes to avoid the environmental difficulties connected with the synthetic coloring compounds. This research focuses on extracting natural dyes from Butea Monosperma plants and on developing sustainable dyeing methods for silk fabric. Natural colorants were extracted using an aqueous and acidic extraction procedure, and the silk fabric was dyed with the extracts using mordanting with a variety of metal and bio mordants. The treatment of fabric and extracts were carried out using microwave irradiation. It was found that after irradiation up to 3 min, the acidic extract shown maximum color strength onto fabric. It was also observed that the acacia and pine-nut hull at 80 °C and before dyeing pomegranate extract at 80 °C and after dyeing of silk fabric at 40 °C using bio-mordants were higher color strength than metallic mordant. For comparative analysis Al salt at 40 °C, Iron salt at 60 °C and tannic acid (T.A.) at 80 °C were provided acceptable results. The color fastness characteristics were also found good to excellent. The bio-mordants not only provide the higher color strength and fastness properties, it was also an environmental friendly approaches. Scanning electron microscopy (SEM) images and Fourier transform infrared spectroscopy (FT-IR) analyses revealed the difference between irradiated and un-irradiated silk fabric. Therefore, it is recommended that MW rays and bio-mordants be used in the natural dyeing of silk fabric because of their deformability and non-toxicity, as well as their high color fastness and color strength properties.

创新地分离单株紫花着色剂用于表面改性丝绸染色

最近，人们对采用天然染料以避免与合成着色化合物相关的环境问题产生了浓厚的兴趣。本研究的重点是从黄豆中提取天然染料植物和开发可持续的丝织物染色方法。使用水性和酸性提取程序提取天然着色剂，并使用多种金属和生物媒染剂将提取物用提取物染色。使用微波辐射对织物和提取物进行处理。发现在照射长达 3 分钟后，酸性提取物在织物上显示出最大的颜色强度。还观察到，在 80 °C 和石榴提取物在 80 °C 染色之前以及在 40 °C 使用生物媒染剂对丝织物染色之后，相思树和松子壳的颜色强度高于金属媒染剂。对于比较分析，40 °C 的铝盐、60 °C 的铁盐和 80 °C 的单宁酸 (TA) 提供了可接受的结果。还发现色牢度特性良好至极好。生物媒染剂不仅提供更高的色强度和牢度性能，也是一种环保的方法。扫描电子显微镜 (SEM) 图像和傅里叶变换红外光谱 (FT-IR) 分析揭示了辐照和未辐照丝织物之间的差异。因此，由于MW射线和生物媒染剂具有易变形、无毒、色牢度和色强度高等特点，建议在真丝织物的天然染色中使用。扫描电子显微镜 (SEM) 图像和傅里叶变换红外光谱 (FT-IR) 分析揭示了辐照和未辐照丝织物之间的差异。因此，由于MW射线和生物媒染剂具有易变形、无毒、色牢度和色强度高等特点，建议在真丝织物的天然染色中使用。扫描电子显微镜 (SEM) 图像和傅里叶变换红外光谱 (FT-IR) 分析揭示了辐照和未辐照丝织物之间的差异。因此，由于MW射线和生物媒染剂具有易变形、无毒、色牢度和色强度高等特点，建议在真丝织物的天然染色中使用。
