Abstract:
Green products such as plant tints are becoming more and more well-known worldwide due to their superior biological and ayurvedic properties. In this work, colorant from Amba Haldi (Curcuma aromatica) was isolated using microwave (MW), and bio-mordants were added to produce colorfast shades. Response surface methodology was used to develop a central composite design (CCD), which maximizes coloring variables statistically. The findings from 32 series of experiments show that excellent color depth (K/S = 12.595) was established onto MW-treated silk fabric (RS = 4 min) by employing 65 mL of radiated aqueous extract (RE = 4 min) of 5 pH cutting-edge the existence of 1.5 g/100 mL used sodium chloride at 75 °C for 45 min. It was discovered that acacia (keekar) extract (1%), pomegranate extract (2%), and pistachio extract (1.5%) were present before coloring by the use of bio-mordants. On the other hand, upon dyeing, acacia extract (1.5%), pomegranate extract (1.5%), and pistachio extract (2%) have all shown extremely strong colorfast colors. Comparatively, before dyeing, salts of Al3+ (1.5%), Fe2+ (2%), and TA (1.5%) gave good results; after dyeing, salts of Al3+ (1%) and Fe2+ (1.5%) and TA (2%) gave good results. When applied to silk fabric, MW radiation has increased the production of dyes recovered from rhizomes. Additionally, the right amount of chemical and biological mordants have been added, resulting in color fastness ratings ranging from outstanding to good. Therefore, the natural color extracted from Amba Haldi can be a sustainable option for the dyeing of silk fabric in the textile dyeing and finishing industries.
摘要:
由于其优越的生物学和阿育吠陀特性,诸如植物色素之类的绿色产品在世界范围内越来越广为人知。在这项工作中,使用微波(MW)分离来自AmbaHaldi(Curcumaaromatica)的着色剂,并添加生物媒染剂以产生不褪色的色调。响应面法用于开发中心复合设计(CCD),在统计上最大化着色变量。来自32个系列实验的结果表明,通过使用65mL的5pH值的辐射水提取物(RE=4min),在MW处理的丝织物(RS=4min)上建立了出色的颜色深度(K/S=12.595)。边缘存在1.5g/100mL使用氯化钠在75°C下持续45分钟。发现金合欢(keekar)提取物(1%),石榴提取物(2%),在使用生物媒染剂着色之前存在开心果提取物(1.5%)。另一方面,染色后,阿拉伯胶提取物(1.5%),石榴提取物(1.5%),和开心果提取物(2%)都显示出非常强烈的不褪色的颜色。相对而言,染色前,Al3+盐(1.5%),Fe2+(2%),和TA(1.5%)给出了良好的结果;染色后,Al3+(1%)和Fe2+(1.5%)和TA(2%)的盐给出了良好的结果。当应用于丝绸织物时,MW辐射增加了从根茎中回收的染料的产量。此外,添加了适量的化学和生物媒染剂,导致色牢度等级从优秀到良好。因此,从AmbaHaldi中提取的天然颜色可以在纺织染整行业中对真丝织物进行染色的可持续选择。
