The study is related to preparing aesthetic textiles using an extract of Acacia arabica wild bark extract. This extract with ferrous sulphate mordant to produce black color on silk fabric using the pad-dry-steam technique of dyeing gave promising results. Aesthetic values of dyed fabric were analyzed in terms of colorimetric parameters i.e. CIE L*a*b* and colorfastness. The attachment of Acacia arabica wild bark compounds with silk substrate has been confirmed by using Infrared Spectroscopy (IR) analysis. The dyed samples exhibit moderate to good washing fastness and very good light-fastness properties. The ultraviolet protection factor (UPF) values ranged from good to excellent for the silk fabrics. The results confirmed that dyeing with natural dyes from Acacia arabica wild bark extract with ferrous sulphate (FeSO₄) as mordant has potential applications in producing black color besides showing good resistance to microorganisms as measured by BPB stain test.

该研究与使用阿拉伯金合欢野生树皮提取物的提取物制备美观纺织品有关。这种含有硫酸亚铁媒染剂的提取物使用轧干蒸汽染色技术在真丝织物上产生黑色，得到了有希望的结果。根据色度参数，即 CIE L*a*b*和色牢度分析染色织物的美学价值。使用红外光谱 (IR) 分析证实了阿拉伯金合欢野生树皮化合物与丝基质的附着。染色样品表现出中等至良好的耐洗牢度和非常好的耐光牢度特性。真丝织物的紫外线防护系数 (UPF) 值范围从良好到极好。结果证实，用天然染料染色以硫酸亚铁 (FeSO ₄ ) 为媒染剂的阿拉伯金合欢野生树皮提取物除了通过 BPB 染色测试显示对微生物的良好抗性外，还具有产生黑色的潜在应用。
