Abstract

The invention relates to a production method of a modified silk fabric. The method comprises the following steps: uniformly mixing quercetin and a reactive ultraviolet absorbent in water, adjusting the pH value of the obtained solution to 9-10.5, and carrying out a reaction to obtain modified quercetin; and adjusting the pH value of the modified quercetin to 3.5, adding a silk fabric, and treating the silk fabric at 75-90 DEG C to obtain the modified silk fabric. The modified quercetin having good water solubility and a good ultraviolet absorbing function is prepared, and is used to treat the silk fabric in order to endow the silk fabric with various functions and a uniform color. The method has the characteristics of simplicity, easiness in implementation, and environmental protection, and the produced silk fabric has excellent bacterium prevention, ultraviolet protection and oxidation prevention functions. The method is a new method provided for solving the problems of poor water solubility of quercetin and inconvenient application in textiles, provides a new idea for the multifunctional finishing of silk fabrics, and has good application prospect.

Description

technical field [0001] The invention relates to the development field of multifunctional textiles, in particular to a modified silk fabric and a preparation method thereof. Background technique [0002] With the improvement of living standards and the change of consumption concept, people pay more and more attention to the living environment and their own health. Based on the consideration of environmental protection and sustainable development and people's pursuit of ecological textiles and green production technology, the development and utilization of natural products have been highly valued. Many natural products have good biodegradability, environmental compatibility and multiple composite functions, so they can be used as green and environmentally friendly colorants and finishing agents for dyeing and functional finishing of textiles. [0003] Natural flavonoids are a class of polyphenolic compounds widely distributed in plants, which have various biological activitie...
