There is a growing interest for producing multifunctional cellulose fabrics using green and sustainable technology. In this study, we explored an eco-friendly procedure for dyeing cotton fabrics with (MS) as a natural colorant and rendering antibacterial cotton fabric by the silver nanoparticles. MS colorants were extracted from dried petals in water using the ultrasound technique, cotton fabrics were dyed with the extracted MS colorant at 100°C for 90 min. The colorimetric data and colorfastness properties were investigated in the absence and presence of tannic acid (TA) as a bio-mordant. Results indicated that MS dye had a high potential for reducing the silver nitrate, so that the silver particle size distribution on cotton fabric was obtained 50-80 nm, and TA had a positive effect on the MS extract and reduced Ag on the cotton. Furthermore, the reduction of bacterial growth of the dyed cotton considerably (up to 99%) improved by AgNPs. The wash-, and light-fastness properties of samples dyed with MS were enhanced from moderate to good-very good by mordanting.
利用绿色可持续技术生产多功能纤维素织物的兴趣与日俱增。在本研究中,我们探索了一种环保工艺,用(MS)作为天然着色剂对棉织物进行染色,并通过银纳米颗粒使棉织物具有抗菌性能。采用超声技术从干燥花瓣中提取MS着色剂,在100℃下用提取的MS着色剂对棉织物染色90分钟。在有无作为生物媒染剂的单宁酸(TA)存在的情况下,研究了比色数据和色牢度性能。结果表明,MS染料具有较高的还原硝酸银的潜力,使得棉织物上银颗粒的粒径分布为50-80nm,TA对MS提取物有积极作用,并减少了棉织物上的银。此外,AgNPs显著提高了染色棉织物的细菌生长抑制率(高达99%)。通过媒染,用MS染色的样品的水洗牢度和耐光牢度性能从中等提高到良好-非常好。
