Comparison of dyeing with cochineal natural dyes on silk fabrics and nylon fabrics
摘要
Abstract
In order to align with the prevailing paradigm of environmentally conscious manufacturing,natural cochineal dyes are employed to impart colour to silk and nylon through the direct dyeing process.The objective of the preliminary experiment was to ascertain the stability of the natural carmine dye.Secondly,the effects of dyeing temperature,dyeing time,dyeing pH and dye concentration on the dyeing performance of silk and nylon fabrics dyed on cochineal dye were investigated,and the dyeing process conditions of the two fabrics were ini-tially explored.The results demonstrated that the optimal conditions for dyeing silk fabrics with cochineal dye were as follows:dyeing temperature 50℃,dyeing time 70 min,pH 3.The optimal process conditions for nylon fabrics were:dyeing temperature 70℃,dyeing time 80 min,pH 5.When the dye concentration reaches 50%,silk fabrics and nylon fabrics have the highest color yield.Subsequently,the colour fastness of the dyed silk and nylon fabrics was evaluated through a performance test.The results demonstrated that both fabrics exhibited ex-cellent colour fastness,with grades exceeding 4.Additionally,the oxidation resistance of nylon fabrics was found to be significantly higher than that of silk fabrics,with an oxidation resistance of up to 63.21%compared to 13.52%for silk fabrics.关键词
