In order to study the dyeing feasibility of lycopene on fabric,the dyeing experiment of polyester imitation silk fabric with lycopene was carried out using ascorbic acid as pigment stabilizer,in which the dyeing fastness of the dyed fabric was evaluated.In the experiment,the absorbance value was utilized to discuss the effect of the ascorbic acid on the stability of lycopene pigment.The dyeing properties of the dyed fabric were studied according to K/S values and L*,a*,b*values,and the fastness of the dyed fabrics was determined.The results show that ascorbic acid can improve the stability of lycopene pigment and protect the color of lycopene.In dyeing process,the K/S values of dyed fabrics can be improved by addition of ascorbic acid in lycopene dyeing liquor,but the depth values can not be enhanced with the excessive addition of ascorbic acid.The dyed fabrics have certain color fastness.
