Study on the overdyeing properties of mulberry leaf tea and lobular red sandalwood on hemp fibers
In order to expand the chromatographic range of natural dye dyeing,mulberry leaf tea and lobular red sandalwood were used to overdye hemp fibers.The effects of mulberry leaf tea concentration,mordant concentration and lobular red sandalwood concentration on the K/S value of overdyed hemp fiber were analyzed as well the color fastness to rubbing,perspiration and soaping of hemp fiber after overdyeing were analyzed.Studies have shown that the hemp fiber dyed with mulberry leaf tea and lobular red sandalwood can obtain a darker purple color.Based on the results of orthogonal experiment and single factor experiment,the optimal process conditions for the overdyeing of hemp fiber with mulberry leaf tea and lobular red sandalwood were obtained as follows:mul-berry leaf tea red sandalwood dye concentration 60％,mordant concentration 10％,lobular red sandalwood dye concentration 100％.Under this condition,the color fastness to rubbing and perspiration of the dyed hemp fiber meets the national wearability standard,and the color fastness to soaping needs is to be improved.
