Abstract

Riboflavin sodium phosphate has been confirmed as a promising biomass product derived from natural plants. In this paper, a novel method of dyeing and multifunctional modification of silk fabric by impregnation with riboflavin sodium phosphate was proposed, such that protein silk fabric can be endowed with bright yellow color and multi-functionality. The results of this paper confirmed that the pH and concentration of riboflavin sodium phosphate solution are critical factors for dyeing and multifunctional modification. Attractively, the photochromic performance was one of the most distinctive features of the modified silk fabric, and the dyed silk fabric turned into fluorescent green from original yellow under 365 nm ultraviolet lamp. Furthermore, the modified silk fabric exhibited good antibacterial properties with a high inhibition rate of 92% for Escherichia coli. Besides, the flame retardancy of silk fabric was significantly improved after modification. The damaged length of modified silk fabric with 40% owf riboflavin sodium phosphate was lower than 10.4 cm and passed the B₁ classification. As revealed by the result of this paper, riboflavin sodium phosphate is sufficiently effective in serving as an ecofriendly multifunctional agent for strengthening the add-value of silk textiles.

生物质核黄素磷酸钠构建可持续着色多功能蛋白丝织物

核黄素磷酸钠是一种从天然植物中提取的有前景的生物质产品。提出了一种用核黄素磷酸钠浸渍对真丝织物进行染色和多功能改性的新方法，使蛋白真丝织物具有明亮的黄色和多功能。结果表明，核黄素磷酸钠溶液的pH和浓度是影响染色和多功能改性的关键因素。令人感兴趣的是，光致变色性能是改性真丝织物最显著的特征之一，在365 nm紫外光下，染色真丝织物由原来的黄色变为荧光绿色。此外，改性真丝织物具有良好的抗菌性能，对大肠杆菌的抑制率高达92%。改性后真丝织物的阻燃性能明显提高。核黄素磷酸钠掺量为40%的改性真丝织物的损伤长度小于10.4 cm，达到B1级。研究结果表明，核黄素磷酸钠作为一种环保型多功能助剂，对提高真丝纺织品的附加值具有充分的作用。
