媒染剂对植物染料在棉麻织物中显色及色牢度的影响
Influence of mordant on the color development and color fastness of plant dyes in cotton and linen fabrics
摘要
Abstract
In view of the common problems encountered when plant dyes are directly applied to cellu-lose fiber substrates,such as low dye-uptake,monochromatic color spectrum,and poor color fastness,this study mainly investigates the mechanism of the dyeing effect on cotton and linen fabrics when several typical plant dyes are combined with metal mordants such as aluminum potassium sulfate,ferrous sulfate,and cop-per sulfate.By measuring the apparent color depth(K/S value),color characteristic values(L*、a*、b*),and color fastness of the dyed fabrics,the influence of coordination complexation between metal ions and dye mole-cules on color development behavior is studied.The results showed that different mordants greatly expand the hue range and increased the color yield by altering the electron cloud distribution of the dye conjugated system,the deposition of metal complexes inside the fibers could improve the wash and rubbing fastness.A comparison of the microscopic adsorption properties of cotton and linen provided theoretical basis and pro-cess reference for the high-quality development of plant dyes on natural cellulose textiles.关键词
