Abstract

In the modern period, scientists are interested in the functional properties of natural materials. The present study is the first report on the use of safflower (Carthamus tinctorius L.) yellow dye extract combined with chitosan bio-mordant for enhancing the anti-bacterial and ultraviolet-protective activities of silk. The presence of flavonoid-based compounds in the dye extract was verified using liquid chromatography–mass spectrometry, Fourier transform-infrared spectroscopy, and ultraviolet-visible techniques. Moreover, alum mordant was also utilised in the silk dyeing process to compare the efficiency of bio and metallic mordanting agents. Experiment outcomes revealed that the chitosan mordanted-dyed silk sustained adequate fastness after being tested by washing, light, wet-rubbing, and dry-rubbing. In addition, superb bacterial inhibition percentages of 89% and 76% against Escherichia coli and Staphylococcus aureus, individually, were accomplished. Furthermore, the ultraviolet-protective behaviour of this silk sample was demonstrated with a 50+ ultraviolet protection factor and low-grade ultraviolet transmittance. This study reveals the great performance of an organic flavonoid dye as a sustainable and environmentally-friendly substance for dyeing and functionalising silk, as well as the efficacy of a green mordant over a metallic mordant in increasing the dyeability and functional activities of silk.

红花（Carthamus tinctorius L.）黄酮类黄色染料提取物与壳聚糖结合用于丝绸的抗菌和紫外线防护功能化

现代科学家对天然材料的功能特性非常感兴趣。本研究首次报道了将红花（Carthamus tinctorius L.）黄色染料提取物与壳聚糖生物协调剂结合使用，以增强蚕丝的抗菌和紫外线防护活性。使用液相色谱-质谱法、傅立叶变换红外光谱法和紫外可见光技术验证了染料提取物中黄酮类化合物的存在。此外，在丝绸染色过程中还使用了明矾媒染剂，以比较生物媒染剂和金属媒染剂的效率。实验结果表明，经过水洗、光照、湿搓和干搓测试后，壳聚糖媒染的丝绸保持了足够的牢度。此外，对大肠杆菌和金黄色葡萄球菌的抑菌率分别为 89% 和 76%。此外，这种蚕丝样品的紫外线防护性能也得到了证明，其紫外线防护系数达到了 50+，紫外线透射率也很低。这项研究揭示了有机黄酮类染料作为一种可持续发展的环保型物质在丝绸染色和功能化方面的卓越性能，以及绿色媒染剂相对于金属媒染剂在提高丝绸染色性和功能活性方面的功效。
