- Abstract
In order to give good antioxidant capacity and dyeing effect to apocynum fiber, chestnut shell brown pigment was carried out and the process optimization of ethanol volume fraction, ultrasonic power, ultrasonic time, extraction temperature and time, experimental analysis were investigated. The antioxidant performance and dyeing effect of the apocynum fiber before and after dyeing were compared. The results showed that the optimum extraction process was 35% ethanol volume fraction, 300 W ultrasonic power, 18 min ultrasonic time, 80 ℃ extraction temperature and 100 min extraction time, and the extraction rate of pigment was increased to 19. 76% once and 26. 97% in five times. The pigment extract showed good antioxidant properties, with the scavenging rate of 21. 56% for hydroxyl radicals and 79. 29% for 1, 1-diphenyl-2-bitter hydrazinyl radicals, and the total antioxidant property was 98.58 μmol / L. The antioxidant and dyeing properties of apocynum fiber dyed with chestnut shell brown pigment were significantly improved, with the scavenging rate of 1,1-diphenyl-2-bitter hydrazinyl radicals up to 51. 21%. The total antioxidant property was 42.95 μmol / L and the color depth value was 2.
